1、中国循证心血管医学杂志2015年2月第7卷第1期ChinJEviBas!!!!!!,!:!!:!9l··论著·拉西地平对高血压模型大鼠血浆内皮素及血管平滑肌细胞CRT表达的影响葛迎晓,李刚,郭惠欣,王东芝,魏毅东【摘要】目的探讨拉西地平对肾性高血压模型大鼠血浆内皮素(ET)及动脉血管内质网应激相关因子钙网蛋白(CRT)表达的影响。方法选择健康雄~Wistar大鼠40只,7-8周龄,随机分为假手术组、模型组、拉西地平组、阳性对照组,每组1O只。假手术组仅分离血管不行缩窄术,模型组、拉西地平组以及阳性对照组大鼠行肾动脉缩窄术。拉西地平组给予拉西地平(0.72mg/kg/d)
2、,阳性对照组大鼠给予卡托普利(35mg/kg/d),手术前1周开始药物干预,每天1次,持续4周,假手术组和模型组给予等量生理盐水。给药4周后,测量大鼠血压,计算平均动脉压;采用免疫组化法测定CRT表达水平;放免法测定血浆Er水平。结果与假手术组比较,模型组平均动脉压升高f(119.83±9.41)mmHgus.(180.75±11.26)mmHg】,差异有显著统计学意义(P<0.O1)。与模型组比较,阳性对照组[(180.75±11.26)mmHgus.(138.68±10.46)mmHg]和拉西地平组[(180.75-4-11.26)mmHgus.(139.54±10
3、.21)mmHg]平均动脉压均降低,差异有显著统计学意义(P均<0.01)。与假手术组比较,模型组CRT表达的AOD值[(0.125±0.04)眠(0.436±O.05)1增加,差异有显著统计学意义(P<0.01)。与模型组比较,阳性对照组大鼠CRT的AOD值【(0.436±0.05)vs.(0.195±0.04)】降低,拉西地平组大鼠CRT的AOD值[(0.436±0.05)vs.(O.209±0.03)1也降低,差异有显著统计学意义(P均4、(P5、sionsofendothelinandcalreticulinofvascularsmoothmusclecellinratsofhypertensivemodelGEYing-xiao*,LIGang,GUOHui-xin,WANGDong-zhi,WEIYi—dong."DepartmentofCardiology,TenthPeopleHospitalofTong#University,Shanghai200072,China.Correspondingauthor:WEIYi—dong,E—mail:ywei@tongji.edu.cn[Abstract]Ob6、jectiveToinvestigatetheinfluencesoflacidipineonexpressionsofendothelin(ET)andcalreticulin(CRT)ofvascularsmoothmusclecell(VSMC)inratsofrenalhypertensivemode1.MethodsMaleWistarrats(n=40,agedfrom7to8w)wererandomlydividedintosham-operationgroup,modelgroup,lacidipinegroupandpositivecontrolgro7、up(eachn=10).Thesham-operationgroupwasnotgivenandothergroupsweregivenrenalarteryconstriction.Thelacidipinegroupwastreatedwithlacidipine(0.72mg/kg/d),andpositivecontrolgroupwasgivencaptopril(35mg/kg/d)onceadayfor4wbeforesurgery.Thesham-operationgroupandmodelgroupweregivenn
