ABSTRACT
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.
