[Effect of regulatory renal polypeptides on hemocoagulation and lipid peroxidation in fluoride intoxication]

Polypeptide cytomedine, isolated from renal tissues has been studied for its regulatory effect on hemocoagulation and lipid peroxidation with fluoric intoxication (FI). FI was caused by inoculation of laboratory animals (guinea pigs) with sodium fluoride (100 mg/kg) for 14 days. Following it polypeptide (0.1 mg/kg) was introduced intramuscularly for 7 days. The development of FI was expressed by hypercoagulation delay of fibrinolysis with para-coagulation products appearing in blood decrease of antiaggregation activity of the renal tissue. These phenomena were estimated as manifestations of the first phase of disseminated intravascular blood coagulability (DIC-syndrome). The above reactions proceeded simultaneously with lipid peroxidation activation decrease of the antioxidant protection. The necrotic-dystrophic processes developed in renal and hepatic parenchyma. The renal peptide-cytomedine induced the normalization of lipid peroxidation in blood and renal tissues and fibrinolysis, the decrease in the concentration of para-coagulation products. The pathological changes decreased both in the renal and hepatic tissues. It is possibly, a result of the normalization of secretion and reabsorption in the kidneys. Thus, cytomedine of the kidney exerts a pronounced regulatory and protective effect in the case of acute renal pathology. These results correspond to the conception of the peptidergic organism regulation.
