According to the absorption spectra of blood and hemoglobin, a photon-bond energy formula is established using physical methods and the effects on hemoglobin of low-level laser at different wavelengths are analyzed. The results show that lasers with the peak wavelengths of 200?240, 275, and 342 nm in the whole blood absorption spectra curve are easy to destroy protein molecules and then lead to hemoglobin lose biological activity. While lasers with wavelengths longer than 800 nm will reduce the oxygen carrying capacity of blood, only lasers with wavelengths between 630 and 670 nm have the best efficacy.
Blue or red: which intravascular laser light has more effects in diabetic patients?
1Department of Medical Genetics, Tehran University of Medical Sciences, Tehran, Iran, email@example.com.
The effects of intravascular laser irradiation of blood (ILIB), with 405 and 632.8 nm on serum blood sugar (BS) level, were comparatively studied. Twenty-four diabetic type 2 patients received 14 sessions of ILIB with blue and red lights. BS was measured before and after therapy. Serum BS decreased highly significant after ILIB with both red and blue lights (p<0.0001), but we did not find significant difference between red and blue lights. The ILIB effect would be of benefit in the clinical treatment of diabetic type 2 patients, irrespective of lasers (blue or red lights) that are used.

The influence of intravenous laser irradiation of the blood on the dynamics of leptin levels and the quality of life of the patients presenting with rheumatoid arthritis.
The objective of the present study was to estimate the influence of intravenous laser irradiation of the blood on the dynamics of leptin levels and the quality of life of the patients presenting with rheumatoid arthritis.
MATERIAL AND METHODS:
A total of 132 patients at the age varying from 18 to 65 (mean 52.9 ± 11.3) years presenting with rheumatoid arthritis (RA) were available for the examination. The diagnosis of RA was based on the results of clinical, laboratory, and instrumental studies in accordance with the criteria of the American College of Rheumatology and European League Against Rheumatism (ACR/EULAR) dated 2010. The patients were divided into two groups. The control group was comprised of the patients who received the traditional medicamental treatment alone (n = 30) while the study group consisted of the patients given a course of intravenous laser irradiation of the blood in addition to the traditional medicamental treatment (n = 102).The course of intravenous laser therapy was performed with the use of a Matrix-VLOK apparatus (“Matrix”, Russia) by means of the VLOK + UBI procedure. Each course consisted of 10 sessions per patient without a break for the weekend.
The data obtained indicate that the patients with rheumatoid arthritis had the increased plasma leptin level suggesting the development of the inflammatory process. Moreover, the quality of the patients’ life was deteriorated.
The results of this study demonstrate that the combined treatment by means of low-intensity laser irradiation is accompanied by the normalization of the plasma leptin level, suppression of the inflammatory process, and a significant improvement of the quality of life of the patients suffering from rheumatoid arthritis.
Effects of Intravascular Low-Level Laser Therapy During Coronary Intervention on Selected Growth Factors Levels.
Abstract Objective: The objective of this study was to evaluate the effect of intravascular low-level laser therapy (LLLT) on selected growth factor levels in subjects undergoing percutaneous coronary interventions (PCI).
Background data: Restenosis remains the main problem with the long-term efficacy of PCI, and growth factors are postulated to play a crucial role in the restenosis cascade.
Materials and methods: In a randomized prospective study, an 808?nm LLLT (100?mW/cm2, continuous wave laser, 9?J/cm2, illuminated area 1.6-2.5?cm2) was delivered intracoronarily to patients during PCI. Fifty-two patients underwent irradiation with laser light, and 49 constituted the control group. In all individuals, serum levels of insulin-like growth factor-1 (IGF-1), vascular endothelial growth factor (VEGF), transforming growth factor-?1 (TGF-?1), and fibroblast growth factor-2 (FGF-2) were measured before angioplasty, then 6 and 12?h and 1 month after the procedure. In all patients, a control angiography was performed 6 months later.
Results: There were no significant differences in IGF-1 and VEGF levels between the groups. While evaluating FGF-2, we observed its significantly lower levels in the irradiated patients during each examination. There was a significant increase in TGF-?1 level in control group after 12?h of observation. In the irradiated individuals, control angiography revealed smaller late lumen loss and smaller late lumen loss index as compared with the control group. The restenosis rate was 15.0% in the treated group, and 32.4% in the control group, respectively.
Conclusions: LLLT decreases levels of TGF-?1 and FGF-2 in patients undergoing coronary intervention, which may explain smaller neointima formation.
Effect of intravenous laser irradiation on some blood biochemical indicators in the acute stage of lacunar infarcts.
To investigate the dynamics of lipid metabolism, C-reactive protein (CRP), lipid peroxidation and antioxidant system in lacunar infarction (LI) in chronic cerebral ischemia.
MATERIAL AND METHODS:
Two groups of patients were studied. The main group included 31 patients who received intravenous laser irradiation ofblood (ILIB) with semiconductor laser (wavelength – 0.67 microns, the power output – 3-2 mW) in addition to standard treatment. Patients of the control group (n=22) received only standard treatment.
A statistically significant decrease in total cholesterol levels to normal values due to the significant reduction of the content of antiatherogenic fraction of cholesterol (high-density lipoprotein and atherogenic low-density lipoprotein cholesterol) was found in the main group after treatment. The reduction in atherogenic cholesterol fractions in both groups was associated with the decrease in apolipoprotein B level. The level of CRP was higher than normal in the main and control groups of patients before and after treatment, which indicated the risk of vascular diseases in patients with LI. After treatment, superoxide dismutase activity returned to normal values. In patients of the main group, the catalase activity increased while the level of reduced glutathione did not change and lipid peroxidation products remained on the high level.
Additional antioxidant therapy is needed for these patients.
[Dynamics of autonomic regulation and daily pH-metry in patients with gastroesophageal reflux disease under the influence of low-intensity laser irradiation of blood].
102 patients with GERD were examined: 70 female (68%) and 32 men (32%). Age of respondents ranged from 20 to 65 years (average of 45.8 ±8,2). All patients were randomly divided into 2 groups. In the first (control) group (30 people) traditional drug treatment were used according to the standard therapy of GERD (proton pump inhibitors, antacids, prokinetics), patients in the second (main) group (70 people) along with drug therapy has received a course of intravenous laser therapy according to the methods ILIB-405. For intravenous laser treatment Russian apparatus “Matrix-ILIB” (“Matrix”, Russia) was used with wavelength 0,405 ?m, output power at the end of the main optical path of 1-1.5 mW. Laser blood irradiation was carried out for 15 minutes in the CW mode, the course of treatment was 10 daily treatments with a break on Saturday and Sunday. Conclusions: 1. Intravenouslaser irradiation of blood in the complex therapy of patients with gastroesophageal reflux disease improved significantly of HRV due to the alignment of parasympathetic regulation circuit and reducing the activity of sympathetic autonomic regulation, 2. the inclusion of intravenous laser irradiation of blood in the complex therapy of patients with GERD was accompanied by reliable normalization of the indicators of the daily pH-metry of the esophagus in patients with GERD.

The influence of intravenous laser therapy on the endothelial function and the state of microcirculation in the patients presenting with rheumatoid arthritis.
The objective of the present work was to study effects of low-level laser irradiation on the endothelial function and selected parameters of microcirculation in the patients presenting with rheumatoid arthritis.
MATERIAL AND METHODS:
This study included 132 patients at the age varying from 18 to 85 years presenting with rheumatoid arthritis. They were divided into 2 groups. The patients of the main group (n = 102) underwent daily intravenous laser blood irradiation during 10 days. The control group was comprised of 30 patients. Laser therapy was performed with the help of a laser therapeutic device Matrix – VLOK (“Matrix”, Russia) using alternation of two radiating heads: KI-VLOK-63 (wavelength 0.63 pm, for 15 minutes) and KI-VLOK-365 (wavelength 0.365 microm, for 5 minutes) in the continuous emission regime. The parameters of interest were measured before and after the treatment. The overall duration of intravenous laser irradiation of blood was 10 days without a break for the weekend.
The data obtained suggest the improvement of the endothelial function and the microcirculation indices.
The application of intravenous laser irradiation of the blood for the combined treatment of psoriasis.
The objective of the present comparative study was to estimate the efficacy of the treatment of 104 patients presenting with psoriasis with the use of PUVA therapy and intravenous laser irradiation of the blood or the combination of the two methods. It was shown that the latter treatment caused a faster reduction of the inflammatory processes than the former whereas their joint application was especially efficacious in inducing regression of concomitant infiltrative events. Erythrocytes from the patients undergoing intravenous laser irradiation of the blood were characterized by the enhanced activity of antioxidative enzymes that are known to play an important role in the cellular protection from oxidants. At the same time, PUVA therapy caused no appreciable changes in the antioxidtive status. Both treatments increased the levels of antiinflammatory cytokines and decreased those ofproinflammatory ones which suggests their immunomodulatory effect that was especially pronounced in the case of combined therapy. It is concluded that the introduction of intravenous laser irradiation of the blood in the combined treatment of psoriatic patients exerts positive effect on compromised immunoregulation, stimulates the antioxidative system, and improves microcirculation.

The application of supravascular laser irradiation of blood for the treatment of cochleovestibular disorders.
A total of 165 patients presenting with neurosensory impairement of hearing and Meniere’s disease were treated by supravascular (extracorporeal) laser irradiation of blood. The study undertaken to evaluate the efficacy of this treatment confirmed its beneficial effect in patients with acute hearing disorders. It was equally effective as regards elimination of labyrinthine hydropsis in patients presenting with Meniere’s disease. The method proved less efficacious for the management of long-standing hearing impairement and chronic loss of hearing, but it can be used to prevent the development of these conditions.

Light distribution in intravascular low level laser therapy applying mathematical simulation: a comparative study.
Li X, Cheng G, Huang N, Wang L, Liu F, Gu Y.
Department of Laser Medicine, Chinese PLA General Hospital, Beijing 100853, China.
Intravascular low level laser therapy (ILLLT) has been applied in the treatment of many diseases for about twenty years. However, much fundamental work has not been done on its dosimetry. The study was designed to compare the difference of light distribution during ILLLT between using flat end fiber and optical fiber coupled with cylindrical light diffuser. Light distribution of He-Ne laser was processed by Monte Carlo model. The laser output was 5 mW. The diameter of both optical fibers was 400 microm. Four tissue optical parameters were chosen for simulation. The results showed that optical parameters of blood are important to determine the distribution of laser energy. The highest power density could increase to over 5000 mW/cm2 using flat end fiber. And the laser energy was absorbed by the blood cells in very small area before the tip of flat end fiber. But when using optical fiber coupled with cylindrical light diffuser, the highest power density was about 100 mW/cm2. More volume of blood cells could be irradiated by laser light. In summary, optical fiber coupled with cylindrical light diffuser is superior to flat end fiber at the aspect of increasing the volume of irradiated blood and decreasing unwanted damage to blood cells during intravascular low level laser therapy.

Types of microcirculation and laser therapy in chronic pancreatitis.
[Article in Russian]
Burduli NM, Gutnova SK.
The aim of the study was to evaluate effect of low-intensity laser therapy (LILT) on systemic circulation in patients with chronic pancreatitis (CP) in the phase of exacerbation. 65 patients aged 36-77 years were divided into study (n = 20) and control (n = 45) groups. In addition, 30 healthy subjects were examined. Patients of the study group received drug therapy combined with intravenous blood or skin laser irradiation. Controls were treated with medicinal preparations alone. CP was diagnosed based on characteristic pain syndrome, compromised secretory function of the pancreas, results of laboratory and instrumental analysis. Microcirculation was studied by laser Doppler flowmetry with a LAKK-02 apparatus (Lazma, Russia). CP patients had heterogeneous microcirculation with a significantly increased frequency of its pathologic types (spastic, hyperemic, spastic-congestive). Major characteristics of microcirculation were significantly different from those in healthy subjects. Combination of drug therapy and LILT substantially improved microcirculation regardless of its hemodynamic type.

Effect of intravenous laser blood irradiation on endothelial dysfunction in patients with hypertensive disease.
[Article in Russian]
Burduli NM, Aleksandrova OM.
The aim of this work was to study effect of intravenous laser blood irradiation (ILBI) on endothelial dysfunction in 120 patients (mean age 53.4 +/- 1.3 yr) with grade I-II hypertensive disease (HD) allocated to 2 groups. Traditional drug therapy given to patients of control group was supplemented by ILBI using a Mulat laser therapy device in the study group. Endothelial function was evaluated from the total plasma concentration of stable NOx metabolites, nitrates (NO3-), nitrites (NO2-), and Willebrand’s factor. HD patients were found to have elevated activity of the Willebrand factor and show 3 types of response of the NO generating system: (1) decreased NO synthesis, (2) lack of its changes, and (3) increased NO synthesis. NO production in HD patients negatively correlated with systolic (r = -0.59) and diastolic (r = – 0.64) arterial pressure (AP) which suggests the relationship between decreased NO production and elevated AP. Inclusion of ILBl in the therapy of HD resulted in a significant decrease of Willebrand’s factor activity and normalization of the NO level regardless of its initial value.

Hemoaggregation dynamics in human-operatory during percutaneous laser blood irradiation.
[[Article in Russian]
Subbotina LA, Radchenko SN, Golovkina OL, Bubeev IuA.
The experiment with essentially healthy male subjects no older than 50 involved functional load testing and irradiation by a low-energy helium-neon laser according to the standard therapeutic regimen (0.2 ml/V/ 30 min/10 sessions). Biomedical evaluation of hemoaggregation was made by 30 parameters of a multifunctional diagnostic system characterizing three blood aggregation levels: rheological (biophysical), coagulolytic (biochemical) and system (mathematical). The investigation resulted in delineation of a single-vector hypodynamic transformation of biophysical and biochemical modules, i.e. decrease in the rheological and coagulative potential mediated by a moderate platelets disaggregation (24.6%) and hyperactivation of plasmin proferments in euglobulin fraction (126.76 %). Added sessions of percutaneous laser irradiation of blood were shown to induce a medium imbalance of biophysical and biochemical hemoaggregation. At the same time, low-energy laser did not modulate significantly the general functional state of human operator as the rheological and coagulative protective potential of organism remained reasonably high (88.89 and 87.5 %, respectively).

BACKGROUND: Low-level laser therapy (LLLT) has been reported to relieve pain, free of side effects. However, the mechanisms underlying LLLT are not well understood. Recent studies have also demonstrated that opioid-containing immune cells migrate to inflamed sites and release beta-endorphins to inhibit pain as a mode of peripheral endogenous opioid analgesia. We investigated whether pre-irradiation of blood by LLLT enhances peripheral endogenous opioid analgesia.
METHODS: The effect of LLLT pretreatment of blood on peripheral endogenous opioid analgesia was evaluated in a rat model of inflammation. Additionally, the effect of LLLT on opioid production was also investigated in vitro in rat blood cells. The expression of the beta-endorphin precursors, proopiomelanocortin and corticotrophin releasing factor, were investigated by reverse transcription polymerase chain reaction.
RESULTS: LLLT pretreatment produced an analgesic effect in inflamed peripheral tissue, which was transiently antagonized by naloxone. Correspondingly, beta-endorphin precursor mRNA expression increased with LLLT, both in vivo and in vitro.
CONCLUSION: These findings suggest that that LLLT pretreatment of blood induces analgesia in rats by enhancing peripheral endogenous opioid production, in addition to previously reported mechanisms.

Efficacy of different laser treatments in combined therapy of patients with gastroduodenal ulcer.
[Article in Russian]
Burduli IM, Gutnova SK.
AIM: To investigate efficacy of different methods of low-intensity laser treatment (LILT) in therapy of exacerbated gastroduodenal ulcer.
MATERIAL AND METHODS: A total of 111 gastroduodenal ulcer (GDU) patients were divided into two groups: the study group (81 patients) and control group (30 patients). Patients from the study group received combined treatment with anti-ulcer drugs and LILT performed by three methods: intravenous laser radiation of blood (ILRB), epicutaneous radiation (ER) and combination ILRB+ER. Control patients received medication alone. The efficacy of the treatment was assessed by the time of ulcer defect heeling, duration of hospital stay, clinical symptoms of the disease exacerbation manifesting with three syndromes: pain, dyspepsia, asthenovegetative syndrome.
RESULTS: The shortest heeling of ulcer defect was achieved in the patients treated with ILRB+ER combination: 17.8 +/- 0.8 and 19.3 +/- 3.4 days for gastric and duodenal ulcer, respectively (p < 0.05 and p < 0.01 vs control).
CONCLUSION: Combined treatment of gastric and duodenal ulcer with inclusion of laser radiation (ILRB, ER, ILRB+ER) is effective in therapy of ulcer.

Intravascular laser irradiation of blood in the treatment of patients with chronic bronchial asthma.
[Article in Russian]
AIM: To investigate action of intravascular laser blood irradiation (ILBI) on production of active oxygen forms (AOF) in patients with bronchial asthma (BA).
MATERIAL AND METHODS: The trial included 59 BA patients aged 20 to 60 years (mean age 40.2 +/- 3.1 years). AOF generation in whole blood was registered with luminol-dependent chemiluminescence (CL). Basic therapy was given to 42 patients. ILBI was added to basic therapy in 17 patients.
RESULT:. CL of whole blood in BA patients depended on severity of inflammation. BA patients with intensive CL exposed to ILBI retained free radical oxidation defects and the disease symptoms. In low intensity of blood CL, ILBI activated A OF generation and raised treatment effectiveness. CONCLUSION: ILBI raises AOF production in the whole blood of BA patients. CL registration can be used for validation of ILBI administration in BA patients and control of effectiveness of laser therapy.

Department of Pulmonology, Clinical Hospital No. 21, Ufa.
The effect of laser radiation on generation of reactive oxygen species in the whole blood from patients with chronic obstructive pulmonary disease was studied by in vitro recording of luminol-dependent chemiluminescence. Laser irradiation of the blood from patients with increased production of reactive oxygen species decreased the microbicidal potential of cells. In patients with low generation of reactive oxygen species and normal potential of cells, laser exposure increased production of O2 metabolites. Laser radiation had little effect on chemiluminescence of the blood in patients with low generation of reactive oxygen species and decreased functional activity of cells.

Effect of low intensive helium-neon laser on superoxide-producing and methemoglobin-restoring activity of cytochrome b558III of rede cell membranes in experiment.
[Article in Russian]
Simonian RM, Simonian GM, Simonian MA, Sekoian ES.
It is established that low-energy He-Ne laser without changes from the side of NADPH-dependent superoxide-producing activity of b558III cytochrome isolated from erythrocytic membranes (EM) promotes b558III activity decrease in EM. The level of metHb-restoring activity increases during irradiation by He-Ne laser. The form of optical spectrum of b558III cytochrome absorption in the visible spectrum area does not undergo essential changes after laser irradiation while optical spectral index (A412/A530) is reduced a little. It is supposed that in the basis of photochemical mechanisms of He-Ne laser protector action in oxidative stress lays its ability to increase EM stability due to a decrease of superoxide-producing and an increase of metHb-restoring activity of b558III cytochrome

Changes of blood paramagnetic centres of animals irradiated with low-intensity laser
[Article in Russian]
Kharaishvili GA, Gogeliia AI.
Therapeutic effects of lasers are based on activation of oxidative process on cellular and subcellular levels. The first photoacceptor of laser beam being mitochondria., which simultaneously represents the source of oxidation products as well as their target and thus, laser exposure can cause numerical effects: inactivation of electron chain components of mitochondria, energy metabolism inhibition, oxidation of lipids and DNA molecule. The aim of the given work is to investigate the influence of submaximal dozes of infrared (0,85 mkm) low-intensity laser on the activity of oxidative processes in laboratory mice blood, which are reflected on the state of paramagnetic centers. For this purpose the condition of blood paramagnetic centers (caeruloplazmin, Fe(3+)-transferin, Fe(2+), Mn(2+), MetHb and NO) has been studied. Results imply that irradiation of mice blood with submaximal dozes of low-intensity laser causes the activation of oxidative process, but those changes do not lead to impairment of blood antioxidant features.

Laser Irradiation of the Blood
Levon Gasparyan, MD, PhD, Jerevan, Armenia
Published jointly in Laser Partner and Laser World (www.laser.nu)
Evaluation of the methods of intravenous a transcutaneous irradiation of blood, known especially from scientific papers of Russian and Soviet authors. The article points out positive effects of laser irradiation on strengthening of the entire immune system.
Intravenous Laser Blood Irradiation Therapy
Currently the methods of laser and non-laser (incoherent monochromic, narrow-band or broadband) light blood irradiation therapy – the methods of photo-hemotherapy – are widely applied in the treatment of different pathologies. Direct intravenous and extracorporeal (with red, UV and blue light) as well as transcutaneous (with red and infrared light) irradiation of blood are used. Unlike the treatment mechanisms of local laser therapy, the medical effects of photo-hemotherapy methods are determined by predominance of systemic healing mechanisms above the local ones, increasing the functioning efficacy of vascular, respiratory, immune, other systems and organism as a whole.
The method of HeNe intravenous laser blood irradiation (LBI) was developed in experiment and introduced in clinic in 1981 by Soviet scientists E.N. Meshalkin and V.S. Sergievskiy. Originally the method was applied in the treatment of cardiovascular pathologies. Some authors reported that the treatment possibilities of the method are very large and include the improvement of rheological characteristics of the blood and microcirculation, normalisation of parameters of hormonal, immune, reproductive and many other systems.
HeNe laser (632.8 nm) is generally used for carrying out the intravenous laser blood irradiation (IV LBI). Usual parameters of blood irradiation procedure are: output power at the end of the light-guide inserted into a vein from 1 up to 3mW, exposition 20 – 60 minutes. Procedures are conducted on a daily base, from 3 up to 10 sessions on a course of therapy.
It was shown, that IV HeNe LBI stimulates the immune response of the organism, activates erythrogenesis and improves deformability of erythrocyte membranes, has anti-hypoxic activity on tissues and general antitoxic influence on the organism at different pathological processes. IV LBI is used for its biostimulative, analgetic, antiallergic, immunocorrective, antitoxic, vasodilative, antiarrhythmic, antibacterial, antihypoxic, spasmolytic, anti-inflammatory and some other properties.
IV LBI activates nonspecific mechanisms of anti-infectious immunity. Intensifying of bactericidal activity of serum of the blood and system of the complement, reduction of the degree of C – reactive protein, level of average molecules and toxicity of plasma, increasing the content of IgA, IgM and IgG in the serum of the blood, as well as decreasing of the level of circulating immune complexes are proved. There are studies on boosting effect of IV LBI on the cellular part of immunity (N. F. Gamaleya et al., 1991). Under influence of IV LBI the phagocytic activity of macrophages markedly increases, concentration of microbes in exudate in the abdominal cavity of patients with peritonitis decreases, reduction of inflammatory exhibiting of disease, activation of microcirculation are detected.
The medical effect of IV LBI is stipulated by its immuno-corrective activity by normalisation of intercellular relationships within the subpopulation of T-lymphocytes and increasing the amount of immune cells in a blood. It elevates the function activity of B-lymphocytes, strengthens the immune response, reduces the degree of intoxication and as a result improves the general condition of patients (V. S. Sergievskiy et al., 1991).
IV LBI promotes improving the rheological properties of blood, rising fluidity and activating transport functions. That is accompanied by increasing the oxygen level, as well as decreasing the carbon dioxide partial pressure. The arterio-venous difference by oxygen is enlarged, that testifies the liquidation of a tissue hypoxia and enrichment the oxygenation. It is a sign of normalisation of tissue metabolism. Probably, the basis of activation of oxygen transport function of IV LBI is the influence on hemoglobin with transforming it in more favorable conformation state. The augmentation of oxygen level improves metabolism of the organism tissues. In addition, the laser irradiation activates the ATP synthesis and energy formation in cells (A. S. Krjuk et al., 1986). Application of IV LBI in cardiology has shown that procedures have analgetic effect, show reliable rising tolerance of patients towards physical tolerance test, elongation of the period of remission.
It was proved that IV LBI reduces aggregation ability of thrombocytes, activates fibrinolysis, which results in peripheral blood flow velocity increasing and tissues oxygenation enriching. The improvement of microcirculation and utilisation of oxygen in tissues as a result of IV LBI is intimately linked with positive influence on metabolism: higher level of oxidation of energy-carrying molecules of glucose, pyruvate, and other substances.
The improvement in microcirculation system is also stipulated by vasodilation and change in rheological properties of blood as a result of drop of its viscosity, decrease of aggregation activity of erythrocytes due to changes of their physicochemical properties, in particular rising of negative electric charge. Finally the activation of microcirculation, unblocking of capillaries and collaterals, improvement of tissue trophical activity, normalisation of a nervous excitability take place (N. N. Kapshidze et al., 1993).
IV LBI is recommended to apply before surgical operations as preparation for intervention, as well as in the postoperative stage, because the laser irradiation of blood has not only analgetic effect, but also spasmolytic and sedative activity.
IV LBI procedures on patients with chronic glomerulonephritis allow overcoming resistance towards medicament therapy (glucocorticoid, cytostatic, hypotensive and diuretic drugs).
IV LBI promotes rising of concentration of antibiotics in the focus of inflammation as a result of improvement the microcirculation in the focus of inflammation, as well as normalisation the morphology and functional activity of the affected organ as a whole.
IV LBI procedures have found broad application in obstetrics and gynecology for activation the blood flow in utero-placental and feto-placental basins, for prophylaxis of the pathologies at delivery, for influence on inflammatory processes of inner genital organs. IV LBI normalises production of gonadotropins, improves microcirculation, elevates oxygen pressure in blood and in tissues, and so accelerates the process of regeneration and reparation.
In order to explain the generalised and multifactor effects of IV LBI, its positive influence practically on all tissues and functional systems of the body, clinical effectiveness for the treatment of different diseases, some authors mentioned that the improvement of microcirculation after IV LBI is detected in all structures of central nervous system, but this improvement is most active in the hypothalamus, which has highly developed vascular system. The capillaries of a hypothalamus are remarkable for high permeability for macro-molecular proteins, which should even more amplify influence of the irradiated blood to subthalamic nuclei. So it is supposed, that IV LBI increases the functional activity of hypothalamus and all limbic system, and as a result the activation of energetic, metabolism, immune and vegetative responses, mobilization of adaptive reserves of an organism is reached.
Transcutaneous Laser Blood Irradiation Therapy
The application in clinics of the non-invasive and relatively simple method of infrared (IR) transcutaneous laser irradiation of blood becomes possible after development of suitable IR semiconductor laser diodes. For transcutaneous LBI lasers with red (630-670 nm) or near IR (800-1300 nm) irradiation band are applied. Laser light is delivered to the skin on a projection of large veins or arteries via special nozzles.
Some recent studies suggested that it is possible to achieve the medical effect similar to effect of IV HeNe LBI, without intravenous manipulations – by transcutaneous laser blood irradiation (TLBI).The procedure of TLBI has the greatest application in children’s practice. The method is founded on a relatively high permeability of the skin and hypodermic tissues for radiation of red and especially of IR spectrum. It is supposed, that the efficacy of 20 mW HeNe laser transcutaneous blood irradiation is equal to 1 mW HeNe laser intravenous blood irradiation. In the same time TLBI procedures are non-invasive and painless. Recently non-laser light sources are also applied for transcutaneous blood irradiation.
Unfortunately, there are not enough qualified works on comparing medical and biological effects of IV and transcutaneous LBI to make the final suggestions about clinical equality of these methods. Brill (1994) suggested that the effects of the laser therapy depend on the method of irradiation. He considered, that the term “transcutaneous laser blood irradiation” is disorientating, as it skips the significance in definition of bioeffect of irritation of receptors of the skin and acupuncture points, dermal cells (including mast cells), aditional elements of the vascular wall and other formations, which are subject to the irradiation. Today there are no ground to consider, that the positive therapeutic effect of laser irradiation of skin is a result of influence only of that part of energy, which penetrates the skin and is absorbed by blood and its components. With good reasons it is possible to speak about transcutaneous laser irradiation, with indication of the place of delivery of laser light.
Blue Light Blood Irradiation Therapy
Currently the methods of laser and non-laser (incoherent monochromic, narrow-band or broadband) light blood irradiation therapy – the methods of photohemotherapy – are widely applied in the treatment of different pathologies.
H. Kost et al. (1986) offered blood irradiation with incoherent narrow-band blue light for the treatment of patients with ischemic heart disease and hypertensive disease. The drop in low-density lipoproteins and cholesterol content of the blood serum was determined. Further studies proved the broad therapeutic activity of the blue light blood irradiation procedures.
In studies of medico-biological effects of extracorporeal blue light irradiation of blood V. I. Karandashov et al. (1996, 2000) detected dropping of viscosity of blood immediately after the reinfusion. The viscosity of the blood plasma also was reduced, but to less degree than viscosity of blood, and had correlation with concentration of blood proteins. All these have results in augmentation of flowability of blood and improvement of microcirculation.
The changes of viscosity of blood and hematocrit are determined by intravascular dilution of extravascular fluid with lower concentration of high molecular weight proteins. After the completing the course of irradiation the viscosity of blood was always lower than it was before the treatment. The decrease of concentration of cholesterol, triglycerides, lipoproteins and glucose was also marked. Thus, the phototherapy by blue light did not damage the blood cells, but stipulated dropping of concentration of atherogenous lipids, glucose and bilirubin. The obtained alterations had tendency to increase and stabilisation at carrying out of a course of phototherapy. At the same time studies showed that blue light does not affect the rheological properties of the blood in vitro.
The infusion of the blood irradiated with blue light had immunostimulative activity for patients with chronic asthmatic bronchitis. It was also shown that immediately after the infusion of irradiated blood all main parameters of respiratory function were improved, and the increasing of effect was detected during and after the course of treatment.
Blue light blood irradiation therapy presents very good results in the treatment of different pathologies. It looks like it combines the best properties of both UBI and LBI procedures. Probably in the near future the blue light blood irradiation therapy will be used much more actively, than today.
ROLE OF THE CIRCULATING BLOOD IN INITIATION OF THERAPEUTIC EFFECTS OF VISIBLE LIGHT
K.A.Samoilova Institute of Cytology of the Russian Academy of Sciences, St. Petersburg, Russia
The successful use in Russia of the extracorporeal and intravascular irradiation of the patient`s blood with the laser and non-laser light for the wound healing promotion, immunomodulation, pain relief, etc. suggests that development of these effect in the case of the percutaneous light application also is due to its effect on blood. Such mechanism seems quite possible, as the visible and IR light penetrating the skin at the depth of 2-4 mm reaches a network of small vessels and can affect the blood that circulates here at a low rate. Since during the laser treatment it is possible to irradiate only a small area of the surface body or wound and, correspondingly, of a very small volume of the circulating blood, it is necessary to explain how its photomodification can lead to a wide spectrum of therapeutic effects. For this purpose, we refer to the data obtained at our Laboratory in studying mechanisms of the rapidly developing functional changes induced by retransfusions of a small blood volume (1.5-2.5% of its circulating pool) irradiated extracorporally with the UV or He-Ne laser light. It has been found out that the optical radiation induces structural-functional changes and activation of blood cells, which results in that a small volume of blood acquires properties of an active preparation able to modulate the state of cells of the autologous blood and other tissues. Indeed, when the photomodified blood is added in vitro to the 10-80-fold volume of the intact autologous blood, it “translates” to it the light-induced changes that, in spite of such a pronounced dilution of blood, not only are not reduced but even are enhanced. As a result, the entire volume of the circulating blood acquires properties of an active preparation. The chief “translators” of the light effects are the irradiated mononuclear leukocytes and platelets, and whereas development of some effects (improvement of hemorheology, activation of all types of leucocytes, etc), is necessarily associated with the presence of irradiated cells, the development of other effects (first of all an enhancement of the growth promoting activity of blood) is initiated by soluble factors secreted by these cells. By now we have accumulated an evidence for that after exposure of a small area of the body to visible incoherent polarized light, immediate changes occur of the rheological, transport, gas transport, growth stimulating, immunomodulating properties of the circulating blood and that these changes develop mainly as a consequence of the effect of the transcutaneously photomodified blood.
EXPERIMENTAL STUDY OF LOW LEVEL LASER RADITIATION EFFECTS ON HUMAN BLOOD CELLS
Siposan D, Adalbert L (Bucharest, Roumania).
Fresh blood from 40 apparently healthy individuals has been irradiated with a low level HeNe laser, using EDTA anticoagulant. Doses ranged between 0-54 J/cm2. The authors watched the relative variation to the received doses of hemoreological constants – erythrocytary and leukocytary indices, as well as the variation of some erythrocytary aggreagability indices-viscocity, BSR. Following irradiation a lowering of the erythrocytary aggreagability (viscosity), BSR, and changes of some erythrocytary and leukocytary indices have been observed. The effect of low-level laser radiation on the red cell confirms the non-resonant mechanism of this bio-stimulating radiation effect by the changes in the cell membrane, in our case the blood cells, by revitalizing the red blood cell functional capacities and by several biochemical effects on the membrane level, that are to be studied thoroughly in future studies. It is concluded that the physical-biochemical and biological effects on blood can influence the physical-chemical parameters needed for long storage of blood products as well as the quick revitalization of the erythrocytary membrane aggressed physically and biochemically, in order to perform its oxophoric function in transfusion procedures.

Efficiency of laser therapy in patients with nonspecific pulmonary diseases
[Article in Russian]
Farkhutdinov UR, Farkhutdinov RR, Farkhutdinov ShU.
Generation of active oxygen forms (AOF) in whole blood was studied in 63 patients with acute pneumonia and 72 asthmatics by chemiluminescence (CL) registration. CL intensity depended on the intensity of inflammatory process. Groups of patients with high and low blood CL were distinguished. In 35 patients intravascular laser exposure of the blood (ILEB) was added to therapeutic complexes. Disorders of free radical oxidation persisted for a long time in the majority of patients with high CL of the blood, treated by ILEB; in many cases the inflammatory process acquired a protracted pattern. By contrast, in patients with low intensity of blood CL, ILEB stimulated the generation of AOF and increased the treatment efficiency. Hence, whole blood CL can serve as a criterion of ILEB prescription and can be used for monitoring the patient’s status during laser therapy.
Dynamics of lipid metabolism and peripheral blood flow rates in patients with atherosclerosis in conjunction with renal dysfunction after the course of combined laser therapy.
Kovalyova T V et al.
During an 8 year period patients with atherosclerosis and renal dysfunction have been treated with intravenous laser blood irradiation (ILBI). The study has demonstrated a decreased level of total cholesterol, LDL cholesterol and triglycerides with an simultaneous increase of HDL cholesterol levels. No pharmaceuticals were given during the treatment period. The authors state that ILBI results in a stable hypolipidemic situation which prevents atherogenesis in patients with metabolic disorders, particularly in patients with renal pathologies.

Departments of Internal Disease and Pathophysiology, Russian State Medical University, Moscow, Russia
We investigated the immunocorrective and clinical effect in 75 rheumatoid patients treated with intravenous laser blood irradiation. A relation between the positive immunotropic (as well as therapeutic) effect and the pre-existent immune status of each patient was revealed. A well-defined effect was found in patients with a low level of CIC and a normal count of functional-competent T-cells. ILIB provided some symptomatic but unstable relief in patients with a high level of CIC and a high functional activity of T-lymphocytes. There was no effect in patients with a high level of CIC and decreased number of lymphocytes.

Cytological parameters of bronchoalveolar lavage in patients with chronic obstructive bronchitis exposed to laser radiation of blood.
Ananchenko V G, Khanin A G, Gostishcheva O V.
Clinicocytological evaluation of the efficacy of combined treatment of chronic obstructive bronchitis (COB) in exacerbation with application of laser radiation of blood was performed. Combined treatment with the use of He-Ne intravenous and transcutaneous radiation of blood was given to 32 patients with COB. 27 COB patients treated without blood irradiation served as control. In addition to conventional methods of examination and control of the treatment effect, cytological and bacteriological tests of BAL precipitate smears were made. Combined COB treatment with the use of laser blood radiation has an antiinflammatory action, promotes normalization of mucociliary transport, activation of phagocytosis and immune defense, cleansing of bronchial tree, reduction of obstruction effective management of exacerbations. Hospitalization decreased 3-4 days. Blood irradiation has the advantages as a noninvasive method.
AN IN VITRO STUDY OF THE EFFECTS OF LOW-LEVEL LASER RADIATION ON HUMAN BLOOD
Dan G. Siposan
In the last time the study of the effects of Low-Level Laser Radiation (LLLR) on the blood is considered to be a subject of great importance in elucidating the mechanisms of action between LLLR and biologic tissues. Different methods of blood phototherapy have been developed and used in clinical purposes with benefic effects. This study investigates some in Vitro effects of LLLR on some selected rheologic indices of human blood. After establishing whether or not damaging effects could appear due to laser irradiation of the blood, we tried to find a new method for rejuvenating the blood preserved in haemonetics-type bags. Blood samples were obtained from adult regular donors (volunteers). HeNe laser and laser diodes were used as radiation source, in a wide range of wavelengths, power densities, doses and other parameters of irradiation protocol. In the first series of experiments we established that LLLR does not alter the fresh blood from healthy donors, for doses between 0 and 10 J/cm3 and power densities between 30 and 180 mW/cm3. In the second series of experiments we established that LLLR does have, in some specific conditions, a revitalizing effect on the erythrocytes in preserved blood. We concluded that laser irradiation of the preserved blood, following a selected protocol of irradiation, could be used as a new method to improve the performances of preservation: prolonging the period of storage and blood rejuvenation before transfusion.

The mechanisms of action of extracorporeal helium-neon laser irradiation in acute exogenous poisonings.
Nemtsev I Z; Luzhnikov E A; Lapshin V P; Gol’dfarb I S; Badalian A V.
Extracorporeal exposure to HeNe laser of 12 mW power was used in 57 patients hospitalised at the intoxication reanimation department with acute poisonings with psychotropic drugs. The clinical result was a decrease of the incidence of pneumonia in the patients with x-ray signs of venous congestion from 52% among those administered to physiochemotherapy to 24% after this treatment modality. Laser hemotherapy brought about a temporary normalization of the erythrocyte membrane permeability, which was changed biophysically by means of a diffractometer. Red cell aggregation was approximating the norm, decreasing by 20%, and platelet aggregation decreased by 17%. Analysis of the results brought as to a conclusion that He-Ne laser exposure is an effective source of singlet stimulation of molecular O2 evenly dissolved in the blood, which causes resonance oscillations of water difields. This leads to membrane depolarization, which is probably responsible for purification of polarised membranes from toxic agents fixed by them.
CHANGES IN SOME FUNCTIONAL AND BIOCHEMICAL PARAMETERS OF THE CIRCULATING HUMAN BLOOD AFTER PERCUTANEOUS APPLICATION OF VISIBLE POLARIZED LIGHT AT A THERAPEUTIC DOSE

Three years ago, our clinics started application of a Swiss phototherapeutic device BIOPTRON that allows an exposure of a small body area to visible incoherent polarized (VIP) light, whose spectrum and power density are close to the Sun visible radiation (400-2000 nm, 95% of polarization, 12 J/cm2). To elucidate physiological mechanisms and to specify indications for this type of phototherapy,we analyzed some biochemcal parameters in 26 healthy volunteers during the course of 10 daily irradiations of a body area, 400 cm2.In the Placebo group (n=16) the irradiation was imitated and 5 exfusions of 140 ml blood for 10 days for study was performed, like in the main group. A rapid statistically significant decrease of the glucose level in 65% of VIP-exposed volunteers (on average, by 10%) has been observed in 0.5 hr after VIP-session but no significant changes in the Placebo group. Subsequently, strongly depending on the initial level, there was a decrease or an increase of this parameter in most VIP-irradiated subjects. The correlation and dispersion analysis has revealed regulatory and normalizing effect of the VIP-sessions on the glucose content. In the Placebo group, this regularity was not detected. Deep changes were in parameters of lipid metabolism: an immediate decrease of triglyceride content, (from 1.14 to 1.00 mmole/l) and its gradual, statistically significant decrease by the end of the course. The analysis indicated both a regulatory and normalizing effect of the VIP-course on the content of these atherogenic lipids The increase in b-lypoproteins’ level was observed in 24 hr as well as by the end of course in both groups. Hence, this effect was due to the hemoexfusion rather than the effect of light.A statistically significant increase of the level of anti-atherogenic lipid a-cholesterol (from 1,76 to 1.98 mmol/l), was found out at all periods of the VIP-course, whereas in the Placebo group this parameter decreased. The data obtained have allowed us to apply the VIP-therapy in 10 patients with X-syndrome. For comparison 10 other patients as well as 12 volunteers were irradiated with therapeutic doses of He-Ne laser light. A small number of examined subjects allows only preliminary conclusions. Unlike volunteers no significant decrease was revealed in the sugar and triglyceride levels, whereas b-lipoproteins’ content decreased soon after the 1st session and by the end of the course of both VIP-therapy and laser treatment (by 32%). As to a-cholesterol, it increased in patients with initially low values and decreased in subjects with high level both after a single exposure to light and by the end of course. There were no significant differences in the studied parameters between the VIP- and laser-treated volunteers.

The promotion of wound healing and immunomodulation are the cardinal indications for laser therapy. Since these complex phenomena involve participation of immunomodulators and growth factors circulating in blood, it is necessary to study effects of phototherapy their level. Using an ELISA, we determined the plasma levels of Il-b, TNF-a, INF-g, Il-10, and transforming growth factor (TGF-b) in healthy volunteers (n=15-20) in 0, 0.5, and 24 hr after exposures of their back (400 cm2) to a therapeutic dose of visible incoherent polarized (VIP) light (Swiss BIOPTRON-2 device, 400-2000 nm, 95% polarization, 12 J/cm2). As a control (Placebo) group, unexposed people were similarly tested after 2 exfusions of blood for study (30-40 ml for 24 hr). There were no changes of the IL-1b level in 0.5 and 24 hr after the VIP-exposure of 17 volunteers, however, the TNF-a content in 0.5 hr changed in 85% of the subjects: a very slight increase was revealed in persons with a low initial cytokine level (50% of all tested) and a more marked decrease, in volunteers with a high initial cytokine level. The inverse dependence of the light-induced effects on the initial TNF-a levels is confirmed by a negative correlation coefficient r (-0.67). In other 22 volunteers a statistically significant increase in the INF-g level was found in 0.5 and 24 hr: its mean amount changed by 44 pg/ml (from 21 to 65 pg/ml), in some people, by 102-308 pg/ml. Meanwhile, in the Placebo group (n=7) a decrease in the INF-g content was observed, which presumably resulted from the hemoexfusion. There also were changes of the Il-10 and TGF-b levels in 78-85% of volunteers, a high dependence of these changes being found on the initial level: r=-0.96 (Il-10) and r=-0.60 (TGF-b). Indeed, in subjects with the low values of Il-10 (40% of cases) its level increased in 0.5 hr (from 9 to 49 pg/m) and, to a lesser degree, in 24 hr, while in the group with the high Il-10 content it fell markedly (from 150 to 5 pg/ml); in the Placebo group a significant increase of Il-10 was observed (from 67 to 126 pg/ml in 24 h). As to TGF-b, its content within 0.5 hr decreased almost twice in 40% of cases (from 20.4 to 11 ng/ml) and rose in the 40% of volunteers 1.5 times (from 7.9 to 11.8 ng/ml). In the Placebo group there was an elevation of the TGF-b level in 60% of the people, while a decrease, only in 27% of the tested persons (by 25%). However, in 24 hr the 2-fold fall of the TGF-b content was revealed already in 71% of the control group persons, whereas among the irradiated volunteers, it was revealed only in 40%. Thus, a single VIP-exposure of healthy people immediately increases the plasma INF-g level and produces a regulatory effect on the TNF-b, Il-10, and TGF-b content.

Effect of intravascular low level laser irradiation used in avulsion injury.
Luo-Q, Xiong-M-G, Gu-H.. Chung-kuo hsiu fu ch’ung chien wai k’o tsa chih
The aim of this study was to explore the effect of intravascular He-Ne laser irradiation on skin flap survival after orthotopic transplantation in avulsion injuries. 58 cases suffering from avulsion injuries were treated by debridement and orthotopic transplantation of the avulsed flap within 6 hours, 31 of them received intravascular He-Ne laser irradiation and routine treatment, 27 received routine treatment as control group. The survival area and quality of avulsed flaps in the experimental group were superior to that of the control group after 15 days of operation, and the hemorheological items were markedly changed at 5 days after operation. The better flap survival after orthotopic transplantation in avulsion injury can be improved by intravascular He-Ne laser irradiation, through changed superoxide dismutase activity and hemorheological items in an optimal irradiation intensity.

Podil’chak MD, Nevzhoda OA.
The plasmapheresis (PP) with the help of the PP-05 apparatus was applied in the treatment of 70 patients with the low extremities diabetic angiopathy. The optimal plasma exfusion dose is from 600 to 1100 ml. Under the PP influence the blood glucose level reduced proportionally to the excreted plasma quantity, the rheovasographic index on the low extremities increased from 0.41 +/- 0.15 to 0.64 +/- 0.6; the bloodflow velocity in the peripheral arteries of low extremities have got the 2.2-fold rise according to the dopplerography data. In comparison with a control group of patients the exarticulation conduction frequency decreased from 20 to 8, and extremities amputation–from 14 to 5.

Intravenous laser irradiation of the blood in severe forms of chronic venous insufficiency
[Article in Russian]
Shval’b PG, Kachinski? AE, Kolobaev VI, Kataev MI.
Based on an analysis of results of treatment of 86 patients the authors have shown that the intravenous laser irradiation of blood results in hypocoagulation, lower hematocrit index. In 52 patients good results of treatment were obtained, in 26 patients results were satisfactory. No complications were noted.
