The article presents the results of studies on the effect of commercial food on the processes of free radical oxidation of lipids in the body of cats with urinary tract pathology. It has been found that the concentration of diene conjugates in the blood serum of sick animals increases significantly by 15.1 - 36.7% relative to healthy ones. The MDA content in the blood serum of healthy animals was 6.05 ± 0.28 nmol / g. In animals with urolithiasis, this indicator increased by about 2 times. When feeding with commercial food and homemade food, LPO processes normalize, which is most pronounced on the 21st day. The average activity of catalase in the blood serum of sick animals was increased from 30.6% to 40.2% relative to healthy ones (15.15 ± 0.61 ?mol / ml). After feeding with therapeutic and prophylactic fodders, by the 7th day, the catalase activity did not significantly decrease compared to the initial level, but remained higher than in control animals by 19.6% - 37.1%. On the 14th day, the catalase activity did not change significantly compared with the 7th day and was higher than the control values by 21.5% - 27.5%.

Aim: To evaluate the intensity of lipid peroxidation and the activity of catalase in patients with laryngeal cancer. Materials and Methods: Samples of blood serum and erythrocytes from 40 patients with laryngeal cancer of stages II and III and 20 healthy volunteers were investigated. Results: The level of TBA-positive products and diene conjugates in blood serum samples of stage II and III patients with laryngeal cancer was increased than that of control. In the same time catalase activity was significantly reduced. In the erythrocytes of patients in both groups the level of diene conjugates and catalase activity was higher than that of control. The level of TBA-positive products increased only in patients with III stage disease. Our results indicate the intensification of free-radical oxidation against the background of the functional stress of the antioxidant defense system in patients with laryngeal cancer, as well as the violation of the structural and functional state of erythrocyte plasma membranes, which is manifested in the activation of lipid peroxidation. This indicates about the formation of a complex of disorders, which can play a significant role in the development and deepening of the pathological process.

Introduction: Production of ethylbenzene and styrene (EBS) is one of the most important stages in organic synthesis. The products have general toxic, hepatotoxic, irritating and narcotic effects on the human body. Severe exposures to EВS can induce pronounced disorders of the central nervous system such as styrene sickness and encephalopathy and of peripheral blood such as leukopenia and lymphocytosis. Materials and methods: We studied homeostasis indices in 376 workers of the main professional groups engaged in the production of EBS including equipment operators, repairmen, and instrumentation and automation fitters. Results: We established an increase in lipid peroxidation by the level of malondialdehyde amid an increase in catalase activity and a decrease in blood retinol and α-tocopherol levels. We also noted an increased activity of indicator enzymes including ALT, AST, GGT, and alkaline phosphatase. Significant changes in lipid metabolism in the form of cholesterolemia, triglyceridemia, a higher atherogenic index, and lower cholesterol of non-atherogenic blood serum lipids demonstrating atherogenic changes in the body were revealed. Conclusions: The earliest prenosological disorders in the body of the examined workers included an impaired hepatic protein synthesis, the development of cytolysis processes and a change in the integrity and functional activity of the liver cell in individuals, an imbalance in the oxidant-antioxidant system, one of the reasons of which was the adverse occupational exposure to hazardous chemicals. An increase in catalase activity is a protective compensatory reaction during the activation of free radical oxidation processes.

Relevance. Optimization of the conservative tactics of acute inflammation of the kidney in nephrolithiasis makes it advisable to use non-traditional methods of detoxification low-intensity laser radiation (LILR) in particular. Aim. To evaluate the effectiveness of laser therapy (LT) in the complex correction of acute secondary pyelonephritis (ASP) in patients with single kidney stones according to the basic adaptation criteria of oxidative-antioxidant clinical medicine КЛИНИЧЕСКАЯ МЕДИЦИНА homeostasis of the organism. Materials and methods. Indices of endogenous intoxication (EI), characterizing the oxidative-antioxidant homeostasis of the body in ASP, were studied in 96 patients with nephrolithiasis aged 19 to 40 years. Patients of the comparison group (48 people) underwent basic (according to the standards) treatment aimed at controlling of calculous pyelonephritis. Patients of the main group (48 people) in the traditional conservative therapy from the second day of hospitalization daily received additional LT sessions with apparatus LTA “Uzor-3KS” with a frequency of 0.6 kHz, a power of 1.5 watts within 4 minutes (total for treatment course is eight procedures). The effectiveness of therapy was assessed on the 5th and 9th day of the inpatient stay. Results. It was found that endotoxicosis in non-destructive forms of ASP is caused by the increase in the concentration of malonic dialdehyde of plasma (by 20.3%) and erythrocytes (by 35.5%), decrease in catalase activity (by 14.2%) and the amount of total (by 11.8%) and free (21.1%) thiol groups with a decrease in the detoxification index (DI) by 24,1%. Compared with the baseline therapy (BT), the effectiveness of LT in the complex treatment of ASP in the analyzed parameters of metabolic homeostasis against the background of the increase in catalase capacity from 6.9 to 10.2%, the detoxification index from 5 to 12.5% was 7.5% (on the 5th day) and 17.5% (on the 9th day of treatment). Conclusions. ASP leads to activation of ROS, suppression of antioxidant and catalase activity of blood, reduction of DI, indicating a subcompensated syndrome of EI. Standard therapy contributes to the normalization of ROS and SLA values of body protection and reduces the level of endotoxicosis caused by ASP. Additional inclusion in the complex treatment of LT sessions more significantly normalizes redox metabolic homeostasis and EI parameters, improving the effectiveness of basic therapy.

Experimental studies were performed on male Wistar rats. Single exposure of animals at doses of 1.0, 5.0, and 9.0 Gy was performed from a source with dose rates of 0.001, 0.01 0.1, and 1.0 Gy/min. The content of diene conjugates was determined at 0.5, 1, 2, 4, 6, 8, 10, 15, 20, and 30 days after exposure. It was found that the content of diene conjugates of blood varied wavy. The relative change in early products per 1 Gy irradiated at doses of 5.0 and 9.0 Gy was 1.5-2.0 and 4-5 times lower, respectively, than in animals irradiated at dose 1.0 Gy. After 4, 6, 8, 10 days, a clear dependence of the indicator on the magnitude of the radiation dose rate was not observed. The dynamics of accumulation of early LPO R products in the blood of rats, irradiated over a wide range of doses and capacities, indicates the nature of the development or inhibition of free radical oxidation processes.

The work purpose was research of degree of free-radical processes intensity and catalase activity in blood serum of patients with a thyreotoxicosis syndrome at traditional treatment and the combined therapy with epifamin. Patients (n=25) have been divided into 2 groups: the first group of patients - 12 persons who are on traditional treatment (antithyreoid drugs, β-adrenoblockers); the second group - 13 persons, are padding to basic therapy received epifamin on 1 tablet (10 mg) 3 times a day 10-15 minutes prior to meal within 7 days. Patients with thyreotoxicosis syndrome had an intensification of free-radical oxidation that was traced at measurement of biochemiluminescence parameters in blood serum. At the combined therapy with epifamin less expressed intensity of free-radical processes, and also increasing of the general antioxidant activity of an organism that did not descend at traditional treatment was observed. At carrying out of standard therapy of thyreotoxicosis syndrome, including application of antithyreoid drugs and β-adrenoblockers, catalase activity decreased, that unfavorable affected antioxidant potential of an organism. At the combined therapy with epifamin level of catalase activity, on the contrary, increased, that could influence positively on antioxidant protection of an organism.

The article presents the results of research on the peculiarities of the functioning of the pro-and antioxidant system of cattle in postnatal ontogenesis in the biogeochemical conditions of the Astrakhan region. The territory of the Astrakhan region is considered to be deficient in the content of selenium in the soil, water and feed, which is confirmed by our research. This is displayed on the body of animals. It was found that the content of selenium in the blood serum is 0.58 mcg/k, which is lower than the physiological value, which leads to the inhibition of the processes of lipid peroxidation in the body of cattle. In the age aspect, the level of diene conjugates and malondialdehyde increases by 7.4-11.4 % and 11.3-16.1 %, respectively. A correlation was established between catalase activity and age (by 19.6% by the 5th year of life). The correlation coefficient is 0.95.

Radical Oxidation

One of the reasons for the increase in disability and mortality among the working population is cardiovascular diseases. Long-term studies of the nature of diseases belonging to this group hypertension, renovascular and malignant arterial hypertension, dyslipidemia, diabetic and dilatational cardiomyopathy, atherosclerosis, ischemic heart disease show that the main cause of pathogenesis is the formation of oxidative stress under the influence of internal and external environmental factors. Mismatch between the processes of free-radical oxidation caused by such active oxygen species as superoxide-anion radical, hydroxide-radical radical, lipid radical, hydrogen peroxide, peroxynitrite, chloric acid and the capabilities of the antioxidant system leads to a disruption of the functional activity of cell structures, displacement of homeostatic balance in the body. Despite the rather deep study of cardiovascular system pathologies, data on the functional activity of myocardial cells under destructive effects and oxidative stress are still insufficient.The article presents the study of the interrelation of the concentration distribution of enzymes of the lipidantioxidant peroxidation system in blood serum and skeletal muscle tissue of white non-pedigree rats. By means of Spearman, Gamma and Kendel Tau correlation coefficients it was revealed a reliable presence of a weak force of inverse correlation between the concentration of catalase in blood serum and skeletal muscle (Spearman R = -0.21 at p < 0.011749, Gamma = -0.14 at p < 0.010977; Kendall Tau = -0.14 at p < 0.010977).
