Aim. The article deals with the assessment of the lipid profile, lipid peroxidation, and antioxidant protection in freestyle wrestlers belonging to different ethnic groups. Materials and methods. The study involved freestyle male wrestlers aged 18–22 with the rank of the Candidate for Master of Sport and Master of Sport regularly practicing freestyle wrestling. We studied a serum consisting of blood plasma and erythrocyte hemolysate. Lipid exchange was studied with the help of the BTS-350 analyzer (Spain) and BioSystems (Spain) reagents. To establish aminotransferase in blood serum, we used Vital (Russia) reagents. The components of lipid peroxidation and antioxidant protection were established with the help of spectrophotometric and fluorometric methods. Results. Freestyle athletes of the Russian ethnic group are characterized by a significantly lower TG concentrations compared to Buryat athletes. In the system of lipid peroxidation and antioxidant protection, in athletes of the Russian ethnic group, we revealed a significant AOA, reduced glutathione and retinol compared to Buryat athletes. Conclusion. The data obtained prove a different degree of metabolic activity in athletes from various ethnic groups. The balance between lipid oxidation and antioxidant protection mostly determines metabolic intensity as well as adaptation capacities of the body. The study of metabolic changes in highly-skilled athletes from different ethnic groups can contribute to the deepening of knowledge about the physiological basis and pathogenetic effects of stress on the human body. This will be one of the factors for optimizing training and providing the search for the ways of increasing physical activity as a mean of preserving the nation and sports development.

Controlled Clinical Study

Dyslipidemia and oxidative modifications of lipid are frequently associated in patients with chronic kidney diseases (CKD) and considered the most important risk factors for cardiovascular events. Melatonin is a well-known potent antioxidant and has beneficial effect on lipid metabolism. the study was designed to evaluate if Melatonin could improve lipid profile and ameliorates lipid peroxidation. This single blind placebo controlled clinical study carried out on 41 patients with CKD who were randomized into two groups, control groups (n=20) those who received placebo cap and melatonin group those who received 5mg melatonin (n=21). Lipid profile [total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL-C), low-density lipoprotein (LDL-C)] and parameters of lipid peroxidation [oxidized LDL (oxLDL) and malondialdehyde (MDA) were measured before and after 12 weeks of the treatment. After 12 weeks of treatment, melatonin significantly increased HDL-C and decreased LDL-C compared to the initial value. The elevation in HDL-C and reduction in LDL-C were significantly different from that in placebo group. Also, both oxLDL and MDA levels significantly lowered by melatonin compared to the baseline and to the placebo group. Collectively, the results of our study showed that melatonin has advantageous effect on lipid profile and inhibit lipid peroxidation in patients with CKD.

Inflammatory Autoimmune Disease

Rheumatoid arthritis (RA) is a highly debilitating chronic inflammatory autoimmune disease most prevalent in women. The true etiology of this disease is complex, multifactorial, and is yet to be completely elucidated. However, oxidative stress and lipid peroxidation are associated with the development and pathogenesis of RA. In this case, oxidative damage biomarkers have been found to be significantly higher in RA patients, associated with the oxidation of biomolecules and the stimulation of inflammatory responses. Lipid peroxidation is one of the major consequences of oxidative stress, with the formation of deleterious lipid hydroperoxides and electrophilic reactive lipid species. Additionally, changes in the lipoprotein profile seem to be common in RA, contributing to cardiovascular diseases and a chronic inflammatory environment. Nevertheless, changes in the lipid profile at a molecular level in RA are still poorly understood. Therefore, the goal of this review was to gather all the information regarding lipid alterations in RA analyzed by mass spectrometry. Studies on the variation of lipid profile in RA using lipidomics showed that fatty acid and phospholipid metabolisms, especially in phosphatidylcholine and phosphatidylethanolamine, are affected in this disease. These promising results could lead to the discovery of new diagnostic lipid biomarkers for early diagnosis of RA and targets for personalized medicine.

The article contains the research results of the effect of cadmium chloride on the indexes of enzyme and nonenzyme systems of  antioxidant defense system in young cattle, such as the activity of catalase, superoxide dismutase, glutathione peroxidase, glutathione levels of vitamins A and E. It is established that feeding calves at a dose of toxicant 0.04 mg / kg activity of catalase, superoxide dismutase, glutathione peroxidase, glutathione levels of vitamins A and E in the blood of experimental animals decreased throughout the experiment. The lowest indicators of antioxidant in the blood of young cattle is set on the twenty -fourth day of the experiment, which is associated with increased activation of lipid peroxidation and the balance between antioxidant system and lipid peroxidation intensity. Given the cadmium load of young cattle it is used a new integrated drug with antioxidant action «Metisevit», which includes metifen, sodium selenite and vitamin E wich is founded as stimulating effects on the activity of antioxidant protection. In particular,it is established probable increase in activity of catalase, superoxide dismutase, glutathione peroxidase, glutathione levels, vitamin A and vitamin E in the blood of young cattle, which has performed cadmium stress. These changes occur through comprehensive action components of the drug «Metisevit» that leads to the normalization of metabolic processes and free radical in the body of the bull. The results of the research indicate antioxidant drug «Metisevit» in the application of its young cattle and the validity of his administration to improve the body's antioxidant status of chronic cadmium toxicosis.

Background: The use of plants known to possess significant antioxidant activities have been widely recommended in the complementary and alternate system of medicine in the treatment of diabetes mellitus. Among the many plant used in Nigeria for the management of DM are Vernonia amygdalina and Ficus exasperata. This study was designed to assess the effect of the combination of the aqueous extract of Vernonia amygdalina and Ficus exasperata on blood glucose level, lipid profile, hepatic enzymes, lipid peroxidation and antioxidant status in alloxan-induced diabetes in rats. Method: Twenty five rats were divided into five groups. Four groups were made diabetic by the intra-peritoneal administration of alloxan monohydrate (150mg/kg body weight) while the fifth group served as normal control. Serum, hepatic and renal concentrations of reduced glutathione (GSH) and thiobarbituric acid reactive substances (TBARS) as well as the catalase activity were determined. The blood lipid profile and some hepatic enzymes were also studied. Result: The combined extract lowered lipid peroxidation, increase glutathione concentration and catalase activity in all the tissues of diabetic rats. The individual extract lowered the total cholesterol LDL-Cholesterol, coronary risk index (CRI), and atherogenic index (AI) while increasing the concentration of HDL cholesterol in alloxan-induced diabetic rats. Diabetes lowered hepatic enzymes’ activities but the leaf extract significantly increased it. Conclusion: It can be concluded that combination of the extracts showed additive effect on each other and it is highly recommended for the management of diabetes.
