【Abstract】 Objective To observe the influence of cyclophosphamide(CTX) on primary cultured hepatocytes and the protective effects of hepatic stimulator substance(HSS). Methods The lactic dehydrogenase(LDH) activities, glutathione(GSH) and malonaldchyde(MDA) contents of cultured hepatocytes were measured. Results CTX increased the leakage of LDH from hepatocytes, at the same time, the content of GSH decreased and MDA increased. These changes were ameliorated partly by HSS. {Conclusion} CTX can induce hepatocytes damage and HSS can protect them by decrease of MDA.;更多还原
