中文摘要
目的研究Bosentan预防低氧诱导的肺动脉高压发生的药效作用,探讨内皮素-1(ET-1)在慢性高原病发病中的作用。方法30只Wistar大鼠随机均分为常氧对照组、低氧对照组和Bosentan组,将低氧对照组和Bosentan组放入模拟海拔为5.5 km的低氧、低压环境中。常氧对照组和低氧对照组ig 0.9%生理盐水,Bosentan组ig 100 mg.ml-1Bosentan水剂,每天2次。饲养15 d后,测量大鼠平均肺动脉高压(PAP)、左右心室比重[RV/(LV+S)]比值。结果Bosentan组大鼠血红蛋白(Hb)、红细胞压积(Hct),ET-1与低氧对照组相比无差异,而PAP、RV/(LV+S)均显著低于低氧对照组(P
