title: The protective effect of Alstonia scholaris R. Br. on hepatotoxin-induced acute liver damage.
abstract: The hepatoprotective effect of Alstonia scholaris R. Br. on liver injuries induced by carbon tetrachloride (CCl4). beta-D-galactosamine, acetaminophen and ethanol were investigated by means of serum-biochemical and histopathological examinations. Post treatment of A scholaris reduced dose-dependently the elevation of serum transaminases level and histopathological changes such as cell necrosis, inflammatory cell infiltration, which were caused by the single administration of 32 microliters/kg CCl4 or 600 mg/kg acetaminophen in mice. A. scholaris significantly lowered 288 mg/kg beta-D-galactosamine induced serum transaminases elevation in the serum-biochemical analysis in rats. A tendency was also shown to inhibit cell necrosis and inflammatory cell infiltration caused by beta-D-galactosamine in histopathological examination. All serological and histopathological effects of A. scholaris were compared with those of Bupleurum chinense, which has been reported previously as a treatment criteria of hepatitis.
