ABSTRACT
The hepatoprotective effect of carnosine was investigated against cadmium-induced acute liver injury in mice. Hepatotoxicity was induced by a single i.p. injection of cadmium chloride (6.5mg/kg). Carnosine treatment (10mg/kg/day, i.p.) was applied for three consecutive days, starting one day before cadmium administration. Carnosine significantly decreased the cadmium-induced elevations in serum aminotransferases. Carnosine suppressed lipid peroxidation and restored the deficits in the antioxidant defense mechanisms (reduced glutathione level, and catalase and superoxide dismutase activities) in liver tissue resulted from cadmium administration. Also, the reductions in hepatic nitric oxide and zinc ion levels, and the increases in hepatic cadmium ion concentration, and myeloperoxidase and caspase-3 activities following cadmium exposure were significantly attenuated by carnosine treatment. In addition, carnosine markedly ameliorated cadmium-induced liver tissue damage as evidenced by light and electron microscopic examinations. It was concluded that carnosine can be considered a potential candidate to protect the liver against the deleterious effect of acute cadmium intoxication.
