1、·356·现代中西医结合杂志ModernJournalofIntegratedTraditionalChineseandWesternMedicine2015Feb,24(4)氮6一环戊基腺苷对大鼠肾缺血再灌注肾细胞凋亡的影响马漫漫,王超,董振明(1.河北省邯郸市中心医院,河北邯郸056000;2.河北医科大学第二医院,河北石家庄050000)[摘要]目的观察氮6一环戊基腺苷(CPA)对大鼠缺血再灌注(I/R)肾细胞凋亡的影响。方法健康SD大鼠32只随机分成4组,每组8只。假手术组(s)组只进行手术操作,不做
2、其他处理;I/R组肾缺血45min再灌注24h;C组给予CPA1.0mg/kg夹闭肾动脉前15min腹腔注射,余操作同I/R组;CD组给予CPA1.0mg/kg和8一环戊基一1,3一二丙基黄嘌呤(DPCPX)1.0mg/kg在夹闭肾蒂前15min腹腔注射,余操作同I/R组。所有动物于再灌注24h处死。肾组织制备肾脏单细胞悬液,经碘化丙啶染色后用流式细胞分析法测定肾脏细胞凋亡率。结果I/R组、C组和CD组肾组织细胞凋亡率明显高于s组(P均<0.05),C组肾组织细胞凋亡率明显低于I/R组及CD组(P均<0.05
3、);1/R组与CD组比较差异无统计学意义(P>0.05)。结论CPA可抑制细胞凋亡,对大鼠肾I/R损伤有一定的保护作用。【关键词]肾;再灌注损伤;氮6一环戊基腺苷;8一环戊基一1,3一二丙基黄嘌呤;细胞凋亡doi:10.3969/j.issn.1008—8849.2015.04.005[中图分类号]R一332[文献标识码]A[文章编号]1008—8849(2015)04—0356—03EfectofN6—-cyclopentyladenosineontheapoptosisofrenalcellsinrats
