A study has been carried out on the effect of the domestic pharmacological armadin long preparation (2-ethyl-6-methyl-3-hydroxypyridine succinate) on the physical working capacity of athletes under the maximum in-tensity force loads characteristic of modern sports. Since pharmacology in sports is constantly searching for non-toxic drugs of the metabolithotropic origin that would have the ability to promote physical efficiency and slow down fatigue without toxic effects on the body, we have chosen for our research a drug based on succinic acid, which is a natural metabolite of the Krebs cycle. It has been shown that the armadin long preparation, when applied on a course for three weeks, positively affects the parameters of special working capacity associated with the improvement of the oxygen-transport function of blood. The metabolic basis of this phenomenon is the inhibition of a decrease in the pH of the internal environment of the body with the subsequent development of lactate-acidosis and the ability of the armadin long drug to accelerate the processes of angiogenesis, and, accordingly, the transport of oxygen to the athlete’s working muscles. The intensity of the formation of new growth factor (VEGF). Such data substantiate the expediency of the use of succinic acid-based agents to prevent negative metabolic changes and to slow down the onset of fatigue in athletes under intense physical loads

Today, sports anemia occurs in elite sports quite often, although it is not a disease (does not apply to ICD-10), but only a pathological condition. Sports anemia is characterized by changes in the red link of the blood, and it is associated with a decrease in the content of erythrocytes and / or hemoglobin. However, this condition leads to a significant decrease in physical performance, and, consequently, the effectiveness of the competitive activity of representatives, first of all, of cyclic sports. Athletes are more sensitive to the effects of anemia and iron deficiency than people who are not constantly exposed to intense physical activity, since performance depends on the maximum oxygen consumption and utilization of active muscles. Sports anemia is often iron deficient, as well as B12 and folate deficient. Therefore, the assessment of various factors accompanying the development of anemia and the development of technologies for the correction of this pathological condition is an important task of sports laboratory diagnostics, as well as pharmacology and nutritional science of sports. Material and methods. We conducted a randomized, double-blind, placebo-controlled study to assess the safety and effectiveness of the effect of a course use of the Santeferra dietary supplement containing liposomal ferric iron in the form of pyrophosphate, vitamins B9, B12 and ascorbic acid on the results of training activities of representatives of cyclic sports with predominantly an aerobic energy supply mechanism. In the course of a dynamic study, which lasted 60 days, the parameters of hematological homeostasis and accumulation, metabolism and transport of iron (content of serum iron, transferrin, ferritin, folic acid, iron binding capacity of serum, saturation of transferrin with iron), as well as the level of serum erythropoietin and the severity of oxidative stress were assessed directly in the membranes of erythrocytes. In parallel, we determined the indicators of aerobic endurance: the absolute and relative values of the maximum oxygen consumption and the PWC170 value. Results and discussion. We found out that in the study sample of 67 athletes who specialized in sports with aerobic energy supply (running disciplines of athletics, rowing and canoeing, triathlon, cross-country skiing), 19 (28.35%) had manifestations of sports anemia, and 23 (34.32%) had latent iron deficiency, which also negatively effect on their physical performance. The course application of Santefrerra, 1 capsule per day for 60 days, helped to normalize the accumulation, transport and metabolism of iron, as well as to significantly reduce the manifestations of oxidative stress that occurs under the influence of prolonged physical exertion. In athletes with anemia and latent iron deficiency, practically no changes in the content of erythropoietin in the blood serum were found. At the end of the course of taking a dietary supplement, the indicators of the relative maximum oxygen consumption in the athletes of the main group increased by 11.5% (P

A retrospective analysis was performed of case histories and of results of sonographic investigations in liquidators of the Chernobyl accident suffering from chronic abnormalities of the biliary ducts. Patients with cholecystitis were studied for the biochemical composition of their bile. The incidence of the gallbladder disorders (chronic cholecystitis, angiocholitis, dyskinesias of the biliary ducts) has not changed much over the last 10 years having elapsed since the accident. The biochemical composition of bile was found to have been changed to a greater extent in the liquidators of the Chernobyl accident than it was in those having avoided danger of exposure to ionizing radiation. Mechanisms of origination of cholelithiasis are discussed on the basis of investigations designed to study biochemical properties of bile and findings secured with the aid of the ultrasound techniques.

Activity was studied of blood serum plasmic enzymes L-serine and L-threonine dehydrogenazes (SDG and ThDG) in 92 liquidators of aftermath of the Chernobyl atomic power plant breakdown, presenting with chronic non-calculous cholecystitis during the stage of moderately severe exacerbation with no clinical and laboratory and sonographic signs of affection of the liver. A quarter of the examinees demonstrated an increased activity of the enzymes under study, which fact is regarded by the authors as a preclinical sign of reactive hepatitis. Recommendations are given as to the outpatient registration and prophylactic management and therapy of those persons having taken part in the elimination of the effects of the Chernobyl accident, presenting with biliary pathologies.
