摘要: 目的 探讨钙通道阻滞剂(CCEB)对肝缺血一再灌注损伤(HIRI)防治作用的机制。方法 制各家兔HIRI模型,动态观察维拉帕米(VP)和地尔硫卓(DT)对肝组织及血中黄嘌呤氧化酶(XO)、超氧化物歧化酶(SOD)活性及脂质过氡化物(LP0)浓度的影响。结果 VP组和DT组OX活性及MDA含量分别显著低于对照纽(均P<0.01),而SOD活性与对照组比较均无显著性差异(均 P>0.05)。结论 CCEB抗HIRI的机制与其降低XO活性、抑制脂质过氧化反应密切相关。

Abstract: Aim The mechanism of caleium channel entry blockers (CCEB) in protecting the liver from ischemia-reperfusion injury was to be explored. Methods With establishment of hepade ischemia-reperfusion injury (HIRI) model, the effects of verapamil (VP) and diltiazem(DT) on xanthine oxidase (XO), superoxide dismutase (SOD) activities and concentration of lipid peroxides (LPO) in the liver tissue and plasma during HIRI were dynamically observed in rabbits. Results The group treated with VP or DT, as com-pared with the control group, showed that XO activity and LPO content all decreased significantly (all P<0.0l)t but there was no difference for SOD activity between VP group and control group or DT group and control group (all P>0.05),. Conclusion It is indicated that mechanism of the protection afforded by CCEB was closely related to its decreasing XO activity and inhibiting lipid peroxidation during HIRI.

Key words: calcium channel entry blockers, xanthine oxidase, lipid peroxides, is-chemia-reperfusion injury
