Abstract： 本实验对12周龄的自发性高血压大鼠(spontaneously hypertensive rat,SHR)及其对照组Wistar Kyoto (WKY)大鼠进行了肾脏移植的研究, 并观察受肾移植大鼠动脉血压的变化以及免疫抑制剂对动脉血压的影响.用尾套法对接受同窝另一同胞WKY大鼠肾脏移植且存活5周的6只WKY大鼠(A组)及接受SHR肾脏移植且存活5周的6只WKY大鼠(B组)的尾动脉收缩压进行检测, 移植前A、 B两组受肾移植大鼠的尾动脉收缩压分别为18.0±0.93 和18.3±0.68 kPa,无统计学显著差异(P>0.05); 移植后3、 4、 5周时, B组大鼠的尾动脉收缩压显著高于A组大鼠, 移植后5周时, A, B两组大鼠的收缩压分别为19.0±0.71 和23.0±0.69 kPa (P<0.001); 所用剂量的免疫抑制剂CsA对双侧肾脏完整以及右侧肾脏切除的SHR、 WKY大鼠的动脉血压无显著影响.以上结果表明, SHR的肾脏在高血压的形成中可能起重要作用.
