Objective To investigate the protective effect of Gabexate mesilate(GM)on D-galactosamine- lipopolysaccharide-indneed acute liver failure in rats.Methods The model of acute liver failure in rats was produced by injection of D-galactosamine(D-GalN)and lipopolysaccharide(LPS).The alanine aminotransferase(ALT),aspartate aminotransferase(AST)in serum and malondiadehyde(MDA)content,superoxide dismutase(SOD)and glutathione peroxidase(GSH-PX)activities in liver homogenate were assayed by spectrophotometry.The levels of turnout necrosis factor-?(TNF-?),interleukin-?(IL-?)and interleukin-6(IL-6)were determined by ELISA method.Hepatic pathological examination was observed.Results 25 mg?kg~(-1),50mg?kg~(1),100 mg?kg~(-1) of GM significantly decreased the serum transaminase activities,the infiltration of inflammatory cells,and MDA content,hut didn't reduce SOD and GSH- PX activities in liver homogenate.GM significantly reduced TNF-?,IL-1?and IL-6 levels in serum.Conclusions GM showed significant protective effects on acute liver failure in rats.
