摘要 目的:探讨镉中毒对血管内皮细胞衰老的影响,为进一步揭示中医病因环境毒邪因素所致血管内皮细胞衰老机制以及中药防护作用,从而为血管衰老的预防和控制提供理论依据。方法:通过人脐静脉内皮细胞培养,分成6组,建立不同浓度氯化镉的模型组和处理西药(硫酸锌)、中药复方(冠心康颗粒剂低、中、高浓度)的治疗组后,继续培养24h、48h,观察SOD、MDA以及端粒酶活性变化。结果:不同浓度氯化镉作用24h、48h后,与对照组比较,各组的端粒酶活性和SOD活力明显下降,MDA含量明显增高(P<0.05)。各治疗组与模型组比较,端粒酶活性和SOD活力增高,MDA含量降低(P<0.05),随着氯化镉浓度不同,各治疗组的表现有差异。结论:镉中毒可造成血管内皮细胞病理损伤,也可引起衰老。硫酸锌和中药复方冠心康颗粒剂对血管内皮细胞镉毒作用具有一定的保护作用,从而可能延缓衰老。
