本文用组织化学方法观察大鼠肝脏缺血不同时间后再灌注时对黄嘌呤脱氢酶(Xanthlne Dehydrogenase简称XDase)活性的影响,同时观察氯丙嗪的保护作用。结果表明,短时间(0.5小时)肝缺血后再灌注,XDase活性和HE染色都无异常改变。长时间(2小时)肝缺血,达到不可逆性损伤后再灌注3小时,可使XDase活性明显减低,再灌注24小时后,HE染色有大面积肝细胞凝固性坏死,氯丙嗪对这种改变有明显的保护作用。
In this paper, the histochemical method was used to observe the effect of xanthine dehydrogenase (XDase) on the reperfusion of rat liver ischemia at different times and the protective effect of chlorpromazine was also observed. The results showed that there was no abnormal change of XDase activity and HE staining in a short time (0.5 hour) after reperfusion. Long-term (2 hours) hepatic ischemia, reperfusion 3 hours after irreversible injury, can significantly reduce the activity of XDase, 24 hours after reperfusion, HE staining with large area hepatocellular coagulation necrosis, chlorpromazine on this Change has obvious protective effect.
