Abstract

Background. Hepatic encephalopathy (HE) is the most severe complication of both acute and chronic liver failure.
Current pharmacotherapy options for HE being limited, it necessitates the search for alternative treatments of this pathology.
Objective – to evaluate the efficacy of S-adenosylmethionine (SAM) in treatment of experimental HE in rats.
Materials and methods. The domestic drug HeptalNAN (Akadempharm, Belarus) has been used as a source of SAM. Rats with thioacetamide-induced HE (350 mg/kg, intraperitoneally, during 3 days) were used in the experiment. SAM in two doses (200 and 400 mg/kg) was administered 4 times via gastric tube. Behavioral tests, biochemical and histological methods were used to evaluate SAM pharmacological effects.
Results. The administration of SAM improved behavioral reactions of animals with HE, decreased the serum concentrations of ammonia and nitrogenous wastes, demonstrated hepatoprotective and antioxidant effects. A low dose of SAM (200 mg/kg) reduced rat mortality and decreased serum concentration of TNF-α.
Conclusion. SAM showed protective effect in experimental HE by improving behavioral reactions, decreasing blood ammonia concentration and having hepatoprotective and antioxidant effects.
