摘 要：AIM To study the effect of hepatocyteapoptosis and necrosis induced by TNF-α on thepathogenesis of acute severe hepatitis(ASH).METHODS The model of ASH was prepared inD-galactosamine(GAIN)sensitized BALB/c miceby injection of either endotoxin(ET)or tumornecrosis factor-α(TNF-α).Morphologicalchanges of apoptotic hepatocytes were studiedby both light and electron microscope and in siteend labeling method(ISEL).Molecular biologicalchanges of DNA ladder were observed byelectrophoresis of extract from liver *** changes were measured by alanineaminotransferase(ALT),asparticaminotransferase(AST)and TNF-α.The relationbetween apoptosis and necrosis was *** The sequence of hepatocyteapoptosis,necrosis,and final death from ASHwas observed both in GAIN/ET and GAIN/*** was prominent at 3.5 h and 5 hafter injection of inducer,while necrosis becamedominant at 9 h after *** appearanceof apoptosis was earlier in GAIN/TNF-α groupthan that in GAIN/ ET *** ofmice with antiTNF IgG1 may completely preventthe liver injury induced by GalN/*** TNF-α can cause liver damageby inducing hepatic apoptosis and necrosis inmice with endotoxemia.
