Hepatoprotective effect of superfine particles of herbal medicine against CCl4-induced acute liver damage in rats.

This study aimed to examine the hepatoprotective effects of the superfine particles of Radix Tetrastigma (SPRT) against CCl4-induced acute liver damage in rats. Animals were treated with SPRT (0.3, 0.6, and 1.2 g/kg) and showed remarkable hepatoprotection against CCl4-induced hepatotoxicity. CCl4 altered various biochemical parameters in rat liver, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), malondialdehyde (MDA), superoxide dismutase (SOD), histopathological changes, and Bax and caspase-3 expressions. SPRT significantly prevented increases in ALT and AST levels, reduced MDA level, decreased Bax and caspase-3 protein expression, enhanced SOD activity, and provided significant amelioration in the histopathological lesions. These findings suggested that SPRT has significant protective effect against acute hepatotoxicity induced by CCl4 in rats.
