The narrowing of the lumen of the trachea due to cicatricial stenoses of the trachea is one of the urgent problems of the modern surgery.  The processes taking place in the trachea and lungs lead to a change in the state of the immune system. Assessment of the dynamics of  indices of nonspecific resistance is one of the methods for assessing  the severity of the course of the disease. We studied the indices of  nonspecific resistance of the organism in narrowing the lumen of the  trachea in an experiment in the early postoperative period.  The study was carried out on the basis of the scientific department  of experimental surgery with the vivarium of Irkutsk Scientific  Centre of Surgery and Traumatology, on 24 white male Wistar rats  with a body weight of 300–350 g. We simulated narrowing the lumen of the trachea by placing a silicone tube in the lumen of the trachea  for 14 days. The parameters of phagocytosis, the state of phagocytic activity of blood neutrophils, spontaneous NBT-test, induced NBT- test were studied. The animals were withdrawn from the experiment  on the 3rd, 7th and 14th day. We revealed that as a result of  narrowing of the lumen of the trachea with the original procedure,  the nonspecific resistance of the organism was violated with  inhibition of the phagocytic activity of leukocytes. There was  inhibition of phagocytic activity of leukocytes and depletion of the  functional reserve of leukocytes.

HGF is one of the factors taking part in regeneration and recovery of liver after injury. The article is dedicated to the study of influence of single HGF intake on the indices of non-specific immune response in rats after 70% liver resection in the early postoperative period. Research was conducted on 42 six-months white male Wistar rats of 250–300 g. It was revealed that level of segmentonuclear neutrophils and lymphocytes in the group with HGF intake stand at normal level on the 2nd day and normalizes to the 11th day that testifies to the decrease of inflammatory response. Increased level of leukocytes and monocytes is registered in the group with HGF intake. Also integrity of non-specific resistance in the early postoperative period on the 2nd day is registered. Suppression of phagocytosis indices with preservation of functional activity of phagocytes was registered to the 11th day.

The aim. Evaluation of the TiO2 effect on the phagocytic activity of peripheral blood neutrophils. Materials and methods. 17 people were examined - 10 people with atopic bronchial asthma (m/f - 5/5, mean age - 38 [28, 48]), verified according to the international criteria, the second group (control) - 7 people - healthy controls (m/f - 3/4, mean age - 23 [21; 26] years). The phagocytic index and neutrophil activity in the NBT-test were calculated for all the examined patients. 0.008% solution of TiO2 (based on 1 mg / kg of body weight) was added to the test-samples, control samples were added with the physiological solution, standard samples - with a suspension of killed Staphylococcus aureus. All the samples were incubated for 30 minutes at 37°C, the ready smears were microscopied with counting the amount of formazan-positive granulocytes in the NST-test and cells that absorbed 1 or more Stf particles per 100 granulocytes. Results. TiO2 stimulated phagocytosis of staphylococcus with blood neutrophils in 53% of the examined patients by 8-30% (p = 0.02). Under the influence of TiO2 activity of phagocytes significantly increased, in comparison with that in spontaneous NST-test (p = 0.0001), but was lower than induction by staphylococcus (p = 0.049). In patients with allergopathology, TiO2 stimulated phagocytosis of staphylococcus and neutrophil activity in the NBT-test was also effective, as was the culture of staphylococcus aureus (31.2% compared to 34.3%). In the healthy group, the TiO2 solution increased the activity of neutrophils in the NST-test, compared with the physiological solution (on average and in 71% of cases by 10-18%), but not so than the culture of staphylococcus (24%, compared to 39, 7%). Among healthy people, there was a correlation between the hereditary of allergy and the neutrophil activity in the NBT-test with TiO2 (0.78). Conclusions. It was found that 0.008% solution of TiO2 stimulated the activity of neutrophils in the NBT-test, both in patients with atopic bronchial asthma and healthy people after 30 minutes of incubation in a thermostat. In patients with allergies, TiO2 increased phagocytosis of staphylococcus, as well as metabolic activity of neutrophils so much as staphylococcus. A strong correlation was found between the hereditary allergies and the increased metabolic activity of blood phagocytes in the NBT-test with TiO2 in healthy individuals.

The work is devoted to the study of the effect of interval hypoxic training on the state of microcirculation of the skin in rats in the experiment. The study was conducted on white male Wistar rats weighing 70 g ±10%. In order to study the state of the dynamic characteristics of blood microcirculation, a change in blood perfusion of the tissue was considered. A non-invasive method for quantifying microvascular perfusion was used. The results showed that inhibition of microcirculation up to 50 % was observed in comparison to this value before exposure during the formation of a compensatory reaction of the body to a hypoxic effect on the 7–14th day of the experiment. It was noted that the predominant role in the regulation of the microvasculature belongs to the passive regulation factor of microcirculation which is characterized by the involvement of blood vessels in the microvasculature due to periodic changes in blood volume in the vessel together with an increase in the arithmetic mean perfusion rate. Thus, experimentally modulated hypobaric exposure, changes the volume of blood in arterioles that is determined by a pulse wave.

The aim of the study was to determine the frequency of occurrence and to assess the significance of markers of pneumocystosis in frequently ill children (FIC) during inpatient treatment and during rehabilitation in a sanatorium. Materials and methods of research: 115 children with recurrent respiratory diseases were observed: 52 were treated in a hospital and 63 underwent rehabilitation in a sanatorium. Biological samples (oropharyngeal swabs, saliva, feces and blood serum) were examined for pneumocystosis. Laboratory techniques used: a polymerase chain reaction (PCR) to detect DNA pathogens, an indirect immunofluorescence reaction (NRIF) – antigens, and immunoforment analysis (IFA) – specific antibodies of immunoglobulins (Ig) of classes M (IgM) and G (IgG). The material for laboratory research was smears from the posterior pharyngeal wall (PCR, NRIF) and blood serum (IFA). Microbiological studies included seeding, isolation of cultures with quantitative counting of colony-forming units in samples of oropharyngeal swabs, feces. Determination of the functional activity of the oropharynx microbiocenosis by the concentration of short-chain fatty acids in saliva by means of GLC method. Phagocytic activity of blood neutrophils was also investigated. Results: in hospital patients, markers for pneumocystis were found in 60% of cases, including the active form (40%) and pneumocystis (13%); in the sanatorium – 33% of cases, with active infection (26%) and detection of pneumocystis (17%). Inpatients were diagnosed with clinical variants of pneumocystis infection: pneumonia, obstructive bronchitis, acute respiratory infections; schoolchildren have been diagnosed with active pneumocystis infection and carriage. Dysbiotic disorders of the loci of the oropharynx and intestines were identified in all examined subjects, inhibition of the phagocytic activity of blood neutrophils and shifts in the concentration of short-chain fatty acids have been observed. Conclusion: a high proportion of active pneumocystis infection (40% and 27% of cases) was revealed in FIC treated in the hospital and in the sanatorium, which represents a risk group for infection/reinfection with pneumocystosis in the premises.

The sufferers of Diabetes Mellitus (DM) in Indonesia is the highest with fourth number in the world, with a mortality rate of 1.2 million in 2012. Because of it, DM research using antihyperglycemic green tea is needed. This study aims to determine the effectiveness of green tea extracts on decreasing fasting blood glucose (KGDP) levels in alloxan-induced white male Wistar rats. Samples were 30 male rats, aged 8-12 weeks, weight ± 200 grams. Rats were grouped into 6 groups with the first group (K1) as a control, the second group (K2) induced alloxan, the third group (K3) induced alloxan with glibenclamide, the fourth group (K4), the fifth group (K5), and the sixth group (K6) induced alloxan with green tea extract as the treatment with dose of green tea extract, 200 mg/kg, 400 mg/kg, and 800 mg/kg. The first, FBG level examination is done 3 days after induction of alloxan using a glucometer. Giving green tea extract was given for 16 days orally, then FBG level re-examined from the tail of rats. One Way ANOVA Test Results, there is the effectiveness of green tea extract on reducing FBG level (p = 0,000). The post hoc Bonferroni test showed that giving 800 mg/kg of green tea extract was the best dose in reducing KGDP close to normal (p = 0,000).

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

The aim of the work was to estimate a wound-healing effect of soft drug products from the Pentaphylloides fruticosa L. shoots on the model of planar skin-fascial wound. The liniment was developed with the use of the NanoDeBee 30 device and the ointment was developed with the use of pharmaceutical technology. Experiments were carried out on white male Wistar rats. The skin injury was simulated by inflicting planar wounds 2.0×2.0 cm in size. The 5%-liniment and 5% ointment from P. fruticosa were put on the wounds of the first and second experimental groups respectively. In the third group the wounds were treated with glycerin-vaseline ointment. Bioptate of the wound surface was taken on the 7th, 14th and 21st day. Histological preparations were studied using standard methods. Cell elements of the first group animals were displayed as fibroblasts and fibrocytes; it was noted high level of collagen organization that testified the effective staging of the wound process in this case. The amount of fibrocytes and fibroblasts and ratio between juvenile and mature forms of collagen-producing cells vary in the first and second groups. Biopsy material obtained from the animals of the third group only on the 21st day corresponded to the picture observed in animals of the 1st group on the 14th day. The findings of the study verify that the use of the product obtained on NanoDeBee device provides the earlier forming of the scar as compared with the ointment developed using pharmaceutical technology.
