摘要
目的 了解甲状腺功能变化对心肌细胞凋亡的影响 ,探讨甲状腺功能异常影响心肌细胞凋亡的机制 .方法 建立实验性甲亢与甲减大鼠模型 (n =2 4) ,检测血清T3 ,T4及促甲状腺激素 (TSH) ,利用末端转移酶介导的缺口末端标记法 (TUNEL)检测心肌细胞凋亡 .结果 正常大鼠及甲亢大鼠未出现心肌细胞凋亡 .甲减大鼠均出现心肌细胞凋亡 ,凋亡程度左心室 >右心室 ,并与血清T3 ,T4 呈负相关 (r =- 0 .834 ,P <0 .0 0 1) ,与TSH呈正相关 (r =0 .941,P <0 .0 0 1) .结论 心肌细胞凋亡与甲状腺功能状态密切相关 ,血液中甲状腺激素参与调控心肌细胞凋亡
