WAYS TO IMPROVE NATURAL FERTILITY.

OBJECTIVE: The aim: Based on the study of the results of retrospective analysis, optimize ways to improve natural fertility. PATIENTS AND METHODS: Materials and methods: Data from the American Society for Reproductive Medicine and the Society for Reproductive Endocrinology and Infertility were used to study this problem. CONCLUSION: Conclusions: With a body mass index > 35, the time reguired for conception increases by 2 times. At the same time, when the body mass index <19, the time reguired for conception increases by 4 times. Increased levels of mercury in seafood are associated with infertility. Smoking accelerates the rate of exhaustion of the ovarian follicular apparatus. When trying to become pregnant, it is advisable to avoid drinking more than 2 servings per day. Caffeine intake over 5 cups/day in women correlates with reduced fertility.

THE EFFECTS OF L-ORNITINE AND L-ARGININE ON THE PROCESSES OF LIPID PEROXIDATION IN THE FUNCTIONAL LAYERS OF KIDNEYS ON THE BACKGROUND OF ACUTE TOXIC HEPATITIS.

OBJECTIVE: The aim is to evaluate the effects of L-arginine and L-ornithine on the processes of lipid peroxidation in homogenates of renal cortex, renal medulla and renal papilla under conditions of acute toxic hepatitis. PATIENTS AND METHODS: Materials and methods: The study was performed on 40 outbred white male rats with experimental hepatitis, caused by carbon tetrachloride. The animals were divided into five groups: control group (the rats were simulated carbon tetrachloride poisoning and its correction by administering of olive oil and normal saline in equivalent doses), acute carbon tetrachloride hepatitis (single intraperitoneal injection of 50% carbon tetrachloride oil solution at the dose of 2 mlxkg-1 of body weight and simulation of treatment by administration of normal saline in equivalent doses), acute carbon tetrachloride hepatitis + L-ornithine (1000 mgxkg-1), acute carbon tetrachloride hepatitis + L-arginine (500 mgxkg-1) and acute carbon tetrachloride hepatitis + combination of substances. RESULTS: Results: On the background of acute carbon tetrachloride intoxication it was observed the development of renal failure in experimental animals, manifested by activation of lipid peroxidation processes in homogenates of renal cortex, renal medulla and renal papilla. The administration of L-ornithine and L-arginine demonstrates positive impact on renal function and hepato-renal syndrome by stabilization of cell membranes and regeneration of functional capacity of injured renal cells. CONCLUSION: Conclusions: The results of our study confirm both the presence of unidirectional effects and absence of toxic influences of L-ornithine and L-arginine on renal cells under the conditions of acute carbon tetrachloride intoxication, which are the most important requirements for modern drugs for the treatment of hepato-renal syndrome.
