Evaluation of biochemical indicators in blood plasma of rats with tetracycline-induced hepatosis and their correction by milk phospholipids

Abstract

Tetracycline is a drug with direct cytotoxic action on the liver, and therefore it is widely used in pharmaceutical studies of therapeutic effectiveness of hepatoprotective preparations. The aim of the present work was to determine the biochemical indicators in blood plasma of rats with tetracycline-induced hepatosis and correction properties of milk phospholipids under tetracycline-induced hepatosis in rats. To achieve this, Wistar rats were administered 250 mg/kg of 4% tetracycline hydrochloride suspension once a day intragastrically. As the corrective therapy, 1% solution of BAS “FLP-MD” was administered in liposomal form based on milk phospholipids. Under modeled steatohepatitis, significant destructive changes were observed in the cell membranes of hepatocytes in experimental rats. It was confirmed by higher activity of transaminase (in particular, activity of АSТ increased 4 times, that of ALT 1.7 times and the AST/ALT ratio was increased 2.4 times in blood plasma). The synthesis of clotting factors in livers of animals with hepatosis was inhibited. The content of fibrinogen in blood plasma decreased by 21%, factor II (prothrombin) by 27.8%, Xa-factor by 27.9%, and protein C by 40.6%. The animals also had hypochromic anemia, azotemia and bilirubinemia. The calcium-phosphor metabolism and hyperkalemia were observed. The liposomal BAS “FLP-MD” based on milk phospholipids diminished harmful effects of tetracycline, in particular supporting blood coagulation factors’ level restoration, and also by the activity of transaminases. According to the results, it may be used in prophylactics and pharmaceutical correction of steatohepatitis.
