摘要
本实验对12周龄的自发性高血压大鼠(spontaneouslyhypertensiverat,SHR)及其对照组WistarKyoto(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180±093和183±068kPa,无统计学显著差异(P>005);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190±071和230±069kPa(P<0001);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。
The experiments were performed on spontaneously hypertensive rats (SHR) and Wistar Kyoto(WKY) rats of 12 weeks old. Systolic blood pressure in WKY recipients receiving an SHR or WKY rat kidney was observed and the influence of immuoinhibitor cyclosporin (CsA) on blood pressure was investigated. The systolic blood pressure (SBP) of tail artery was measured by tail cuff technique in 6 WKY recipients of one SHR kidney and 6 WKY recipients of a WKY kidney from before transplantation to 5 weeks after transplantation. At the time when kidneys were harvested for transplantation from 12 week old SHR and WKY rats, the SBP in WKY recipients was not significantly different. The SBP in WKY recipients of an SHR kidney was significantly higher than that in WKY recipients of a WKY kidney at 3, 4 and 5 weeks after transplantation. The immunoinhibitor CsA exerted no effect on the arterial blood pressure in either intact or uninephrectomized SHR and WKY rats. The results indicate that the kidney of SHR plays an important role in the pathogenesis of genetic hypertension.
