多西他赛对野百合碱诱导的大鼠肺动脉高压的治疗作用
【目的】研究多西他赛对野百合碱诱导的大鼠肺动脉高压的作用及可能机制。【方法】50只雄性SD大鼠随机分为5 组:正常对照组(control)、多西他赛组(control+DTX)、野百合碱组(MCT)、野百合碱+溶媒组(MCT+SOL)和野百合碱+多西他赛组(MCT+DTX)。后3组大鼠一次性腹腔注射野百合碱(60 mg/kg)建立肺动脉高压模型。野百合碱注射后第21天和第28天,经尾静脉注射多西他赛(5 mg/kg)或溶媒进行干预。多导生理记录仪测定大鼠右心血流动力学,计算右心室肥厚指数(RVHI);左肺病理切片行van Geison染色,光镜下观察肺内小动脉病理改变,并计算肺小动脉中膜厚度与...
