 The aim: to study the content of a-amylase in oral fluid in healthy young people (mean age 18 years), depending on the presence of a predictor of inflammatory diseases of the oral cavity in physiologically adjusted drinking behavior against the background of educational stress. Material and Methods. For three months, we studied three groups: the main group (30 people, consumed water 30-35 ml per 1 kg of body weight treated with the electromagnetic device), a placebo group (30 people used water 30-35 ml per 1 kg of body weight, but consumed water with a placebo device that does not have an electromagnetic base) and a control one (25 people who do not change their water drinking behavior). To identify the features of sAA oscillations, all groups were divided into subpopulations with predictors of inflammatory diseases of the oral cavity (IL-1(3>212 pg/ml) and without such status (IL-1(3<212 pg/ml). The level of a-amylase activity was determined by a colorimetric method on Cobas C111 automated equipment (Roche), the concentration of IL-1J3 was detected by ELISA on an Infinity F50 photometer (Tecan). Results. Secretory alpha-amylase activity by the end of the study decreased in the main group; in the placebo and control groups, baseline values were exceeded. In the subpopulations with predictors of inflammatory dental diseases (IL-1(3<212 pg/ml) of the main group, the sAA activity decreased by 2.5 times; in the subpopulations without predicates of inflammatory changes (IL-1(3 <212 pg/ml), a significant decrease in enzyme activity in the main group was observed and an increase in the control. The percentage of sympathotonics at the end of the experiment in the main group was lower than in the placebo and control groups. Conclusion. A relation was found between a decrease in the level of a-amylase activity in the oral fluid and corrected water drinking behavior in a subgroup of people without predictors of inflammatory diseases of the oral cavity, using water in an amount of at least 30-35 ml/kg body weight that was purified by an electromagnetic method.

Aim: comparative assessment of the state of joint (hyaline) cartilage, pro-inflammatory component of cytokine profile and enzyme element of blood antioxidant system in healthy individuals and patients at the early stages of gonarthrosis. Materials and Methods. The content of cartilage oligomeric matrixprotein (COMP), superoxide dismutase-2 (mitochondrial) (SOD-2) and interleukin-1 (3 (IL-1 (3) was studied in 34 individuals with initial signs of gonarthrosis (main group) and in 20 conventionally healthy individuals (control group) in blood serum by ELISA. Results. In the serum of patients with GA, the content of COMP (Me=20.67 pg/ml; 25% quartile 14.70; 75% quartile 27.15) and IL-1(3 (Me=4.74 pg/ml; 25% quartile 3.93; 75% quartile 5.90) was statistically significantly higher (p<0.05) than in the control group: COMP (Me=15.27 pg/ml; 25% quartile 8.86; 75% quartile 20.76 and IL-1(3 (Me=3.59 pg/ml; 25% quartile 2.75; 75% quartile 3/83). A correlation analysis in the control group revealed a positive strong correlation between COMP and IL-113 (r=+0.70; p=0.01) and a tendency toward a negative moderate association between COMP and SOD2 (r=-0.43; p=0.08); in the main group between these indicators, the connections were weak, statistically insignificant. Conclusion. Patients in the early stages of primary GA compared with healthy individuals confirmed the presence of destructive processes in the articular (hyaline) cartilage and the activation of the proinflammatory element of the cytokine profile and the enzyme level of the antioxidant system of the blood. The correlation analysis revealed a decrease in the strength of functional links in patients with GA, between the indicators of COMP — IL-1 (3 and COMP — SOD2, which indicated a change in the regulatory effects of proinflammatory cytokines and the enzyme element of the antioxidant system of the blood on the structural-metabolic state of the articular (hyaline) cartilage in the initial stage process.

The cytokine status and the levels of thyroid hormones in children with acute respiratory viral infections

The research goal is to study the performance of INF-а, INF-y and IL-1(3 in children with acute respiratory viral infection (ARVI) depending on etiology, the presence of mixed infection, disease severity, presence of complications, the concentration of thyroid hormones. Material and Methods. Examined 147 patients aged from 1 to 10 years at the outbreak of the ARVI and 15 healthy children. Patients in the midst of acute respiratory infections was conducted to determine levels of IL-1(3, INF-а, INF-y, triiodothyronine (T3) and free thyroxine free (T4) by ELISA using standard test kits JSC "Vector-best" (Koltsovo, Novosibirsk region). Results. It was showed elevated level of INF-y in patients with PC-infection in comparison with the same indicator in healthy children. Set the increased level of INF-а in severe ARVI and the level of INF-y at medium severe form. It was showed increased levels of INF-y in patients with mixed infection. In children with complications, the level of IL-1 (3 was lower almost in 2.4 times, than in children without complications. Among patients with complications, the highest numbers of INF-а were detected in children with pneumonia and INF-y increased in patients with bronchitis. When conducting correlation analysis, the highest rates of INF-а were observed in children with the syndrome of "low T3", and INF-y in children as low T3 and low T4. Conclusion. An increase in the level of INF-y in patients with RS infection was found. Revealed that in children in acute period of SARS levels IL-1 IS, INF-а do not depend on the etiological factor of SARS. These indicators are influenced by the severity of the disease, which in our study was due to the development of mixed infection, the presence and nature of complications. High rates of INF-а and INF-y have significant inverse correlation with the level of T3, which reflects the degree of intoxication in the acute period of infectious diseases.

The aim of the study is to determine the diagnostic value of urine biomarkers of inflammation (interleukin-1p, tumor necrosis factor-a), angiogenesis (vascular endothelial growth factor) and fibrogenesis (monocyte chemoattractant protein-1, matrix metalloproteinase-9) to assess the severity of urodynamic obstruction of the ureter. Materials and Methods — Complex investigation of 47 children with congenital nonrefluxing megaureter at the age from 1 month till 11 years is carried. Results. The correlation between the urine level of IL-1p and main laboratory criteria of inflammation occurred, so IL-1p as an integrative indicator of pyelonephritis activity was appeared. The relation between levels of VEGF and MCP-1 and indicators of renal hemodynamics allowed to consider increased levels of these factors as markers of irreversible nephrosclerosis. The urine level of MMP-9 was strongly correlated with parameters of peristalyic activity of the ureter. The group of children with lower peristalyic activity of the megaureter was significantly different from group with normal ureteral peristalsis by the high urine level of MMP-9. We do not have reliable data about the diagnostic value of determination of the urine level of TNF-a in children with congenital megaureter. Conclusion: The urine level of biological markers investigations are very important for clinical practice for determination of pyelonephritis activity (IL-1p), severity of ischemic deterioration of renal parenchyma (VEGF, MCP-1). Further studies are needed to clarify the pathogenic role of MMP-9 in the regulation of peristalyic activity of the ureter during embryonic and postnatal development in patients with congenital nonrefluxing megaureter.
