The effect of low-intensity laser radiation on the biochemical, immune and clinicalstatus of hypotrophic calves was studied. The studies were carried out in 2 groups(test and control ones) of 12 animals with symmetric moderate hypotrophy. Thecalves in the test group underwent low-intensity laser irradiation of blood withinthe red spectral range (wave length of 630 nm). The animals of the control group(intact) were not treated. Clinical observations of the calves were carried out during2 months, taking into account the incidence, duration and severity of the course ofthe disease, as well as the calves’ weight gain. Blood sampling for biochemical andimmunological studies was performed on the 1st and the 21st days of the calves’life. On the first day the biochemical status and natural resistance in the animals ofthe both groups did not differ. On the 21st day, the calves of the test group hadhigher levels of glucose, pyruvic acid, vitamin E, Blood Serum ComplementActivity (SCA), Blood Serum Lysozyme Activity (SLA), Leucocyte PhagocyticActivity (LPA), Phagocytic Number (PN), Phagocytic Intensivity (PI), and lowerlevels of lactic acid, middle molecules and ectoglobular hemoglobin in comparisonwith the control group. The treatment of the animals with low-intensity laserradiation positively affected their clinical state and productivity. The calves in thetest group had mild forms of gastrointestinal diseases with a shorter courseduration, and the increase in body weight was significantly higher compared withthe control group. The positive effects of low-intensity laser radiation onbiochemical status, natural resistance and clinical condition of hypotrophic calveswere established, which allows us to recommend it for their rehabilitation.

The effect of low-intensity laser radiation on the biochemical, immune and clinical status of calf-malnutrition was studied. The studies were carried out in 2 groups (experimental and control) for 12 animals with symmetric hypotrophy 2 (medium) severity. The calves of the experimental group underwent irradiation of blood with low-intensity laser radiation in the red spectral range (wavelength 630 nm). The animals of the control group were not treated (intact). Clinical observations of the calves were conducted for 2 months, taking into account the incidence, duration and severity of the disease, as well as weight gain. Blood sampling for biochemical and immunological studies was performed on the 1st and 21st days of life. Treatment of animals with low-intensity laser radiation positively affected their clinical state and productivity. Calves of the experimental group compared with the control were ill with gastrointestinal diseases in mild form with shorter duration of their course, and weight gain was significantly higher. The positive effects of low-intensity laser radiation on biochemical status, natural resistance and clinical condition of hypotrophic calves have been established, which allows us to recommend it for their rehabilitation.

Low-intensity laser therapy aims at pain suppression, edema reduction and acceleration of wound healing. The main goal of this study was to clinically evaluate the effects of Aluminum Gallium Arsenate laser - 670nm in wound healing after gingivoplasty in 11 patients. Surgery was performed in anterior superior and/or inferior regions. The right side of the patient (test group) received a laser energy density of 4J/cm², in a 48-hour interval, during one week, totalizing four sessions. The irradiation was punctual in a contact mode in three points. The left side did not receive irradiation (control group). Clinical evaluation was performed by five specialists in periodontology through photography of the treated areas at post-surgical periods of 7, 15, 21,30,60 days. The observers pointed the best healed side. The Sign test was used for statistical analysis with a confidence level of 5% (P<0.05). The examiners found a better pattern of healing sometimes in the test and sometimes in the control group until 21 days after surgery. After this period there was no apparent difference between them. There was no statistical difference between the sides (p>0.05). These results have shown that low-intensity laser therapy did not accelerate oral mucosa healing after gingivoplasty.

Objective. The study presents results of the low-intensity intravenous (IV) laser radiation effect on some indicators of the hemostasis system and respiratory function of 83 patients with a chronic lung disease (COPD), stable phase, II-III (after GOLD scale), including 51 men and 32 women. The average COPD duration was 9.6±4.4 years. Materials and methods. All patients with COPD were randomly divided into 2 groups - comparison (30 people) and main (53 people). The control group consisted of 20 practically healthy people, matched by sex and age. Patients in the control group received only standard drug therapy with IGCC/DBA combination (budesonide/formoterol, salmeterol/fluticasone propionate inhalation at a therapeutic dose corresponding to the COPD clinical symptoms severity). Result and Discussion. In addition to the basic treatment, the main group received a course of intravenous lowintensity laser radiation. As established before the treatment initiation, patients with COPD experienced a decrease in FEV1, Tiffno index, SaO2. Conclusion. The respiratory function disruption was accompanied by a significant activation of plasma hemostasis ( prothrombin time shortening, thrombin time, activated partial thromboplastin time) and a significant increase in platelet aggregation (increase in the aggregation degree, aggregation rate, decrease in the aggregation time). At the same time, in patients with COPD, a significant decrease in anticoagulant activity was observed before treatment, particularly antithrombin III decrease when compared with the control group (p <0.05) and CRP (main group: 0.86±0.02; control group: 0.85±0.02). The introduction of low-intensity laser radiation into the patients complex with COPD led to the these parameters normalization. Bangladesh Journal of Medical Science Vol.18(3) 2019 p.586-592

Aim. Study the effect of low-intensity laser radiation on the genotype's young sheep (poll Dorset x North Caucasian meat-wool) and their exterior. Material and Methods. Zootechnical, biophysical, statistical and other methods were used in research. Experimental animals were exposed to an STP laser apparatus, the action of which is based on the use of low-intensity laser radiation in the infrared region of the spectrum. The study of measurements of animals at the age of 5 and 7 months was carried out and physique indices were calculated. Results. Comparing measurements in the studied animals at 5 months of age revealed the advantage of lambs of groups II and III over the control, in almost all main parameters. However, the experimental groups' young animals were characterized by higher rates of breast measurements. Thus, the superiority of lambs of groups II and III over animals of the control group were: in chest depth 2.1-3.3%, width – 4.4-7.1%, girth – 1.2-4.1% (P < 0.001). A similar trend was established due to measurements of the studied animals' physique at the age of 7 months. At the same time, a clear advantage in terms of measurements characterizing breast development was found in young animals of the second and, especially, in the third group: in chest depth by 3.8-7.4%, width by 4.8-9.1%, girth – 3,7-9.0%, with a significant difference (P < 0.05; P < 0.001). It was also found that the greatest value of the breast index at 5 months of age was typical for animals of groups II and III (77.6-78.6%), which is 1.8-2.8 abs. percent (P < 0.001). However, with age, the difference in the value of this indicator between the groups decreased. Therefore, at the age of 7 months, young animals of groups II and III surpassed animals of group I in this indicator by 0.8-1.5 abs. percent. Conclusion. Thus, it was found that the best ratio of most body articles and body build indices, characterizing them as animals with well-pronounced meat forms, were animal groups II and III.

A clinical and immunological examination of 140 women with verified cipher B 37.3-inflammatory disease caused by yeast-like fungi of the genus Candida, characterized by the presence of 4 or more episodes during the year, is carried out. Before the start of therapy, an imbalance of cellular and humoral factors of innate immunity, the content of cytokines in the vaginal secretion, was detected. The optical radiation of a low-intensity laser was included in the scheme of therapeutic measures, starting from the first day of treatment. The results of the study demonstrate that local exposure on the vulva and vagina with laser radiation with a wavelength of 635 nm, with the power of 5 mW, for 10 minutes per area for a 10-day period reliably reduce the severity of objective and subjective symptoms of vaginal candidiasis, reduce the number of relapses, forming a long interrecurrent period, and normalizes the state of factors of local antimicrobial protection on the surface of the mucous membranes of the lower part of the urogenital system.

The immune system is central to ensuring the consistency of the body's homeostasis. The state of the body's natural resistance is determined by a set of non-specific protective mechanisms. Lymphocytes and phagocytes are actively involved in maintaining immunity. Lymphocytes recognize the antigens of pathogenic microorganisms, and phagocytes absorb and destroy the pathogens themselves. During the weaning of piglets from sows there is a decrease in the protective forces of their body. During this period, the natural resistance of the piglets is reduced due to the stressful situation caused by changing conditions of confinement, the transition to full feed and lack of sows. The immune system of weaning pigs is relatively weak, so when exposed to environmental and technological stressors, they become susceptible to various diseases. The use of probiotic drugs stimulates the activity of the immune system, prevents stress and immunodeficiency. One of these probiotics is the probiotic of domestic production Protecto-active. It w observed the the influence of the probiotic Protecto-active on the indices of nonspecific resistance of the young pigs organism to the growth. An increase in bactericidal activity of blood serum by 12.10% (P <0.05) and lysozyme activity of blood in the piglets of the experimental group was increased by 3.71% compared to control, which indicates the activation of the body's defenses and the increase in adaptive capacity. An important step in the study of the influence of the probiotic Protekto-active on the state of the immune system is to determine the phagocytic activity of neutrophils, phagocytic index and phagocytic number. In the experimental group of piglets that were fed the probiotic Protecto-active, we found an increase in leukocyte phagocytic activity by 9.0% (P <0.001), a phagocytic index by 51.7% (P<0.001) and a phagocytic number by 24.8% ( P <0.01) compared with the control group. Thus, using a probiotic Protecto-active, all indicators of phagocytosis increase: the number of phagocytes increases, their ability to capture microorganisms and increases their digestive capacity, it increases the bacterial and lysozyme activity of blood serum, which is positively reflected in the immunobiosity. Key words: probiotic, phagocytosis, phagocytic index, phagocytic number, phagocytic activity of leukocytes, cellular immunity, piglets
