Abstract
探讨加味二陈汤对脾虚痰湿证模型大鼠肺表面活性物质(pulmonary surfactan,PS)相关蛋白A(pulmonary surfactant-associa ted protein A,SP-A)、相关蛋白B(pulmonary surfactant-associa ted protein B,SP-B)表达的影响.采用甘蓝饲喂、猪脂灌服和香烟烟熏的方法建立脾虚痰湿证大鼠模型,加味二陈汤进行治疗,免疫组化法检测SP-A、SP-B表达的变化.结果表明,与健康组比较,模型组大鼠SP-A和SP-B阳性面积明显减少,平均光密度值显著降低,有显著差异(P<0.01);与模型组比较,各治疗组SP-A和SP-B阳性面积显著增加(P<0.01),平均光密度值有不同程度增加,以治疗Ⅱ组大鼠最为明显(P<0.01).说明加味二陈汤可显著提高模型大鼠SP-A和SP-B表达,对脾虚痰湿证的发生起到改善作用.
