【摘要】 本试验选用纯种日本大耳白兔，随机分为平原组（海拔３９７米），高原组和高原给药组（海拔３９００米），分别检测实验动物外周血液的三项指标。得知；高原给药组的红细胞（ＲＢＣ）计数，明显低于高原组（Ｐ＜０．０５）。此外，高原给药组血红蛋白（Ｈｂ）含量、红细胞比积（Ｈｃｔ）均值都低于高原组。结果提示：异叶青兰对家免造血系统的低氧性改变有肯定的保护作用。更多还原

【Abstract】 he rabbits born Xian city(397m) were chosen and randomly divided into plain group, plateau group and plateau-herb group.After the rabbits were sent to high altitude area(3900m)and took Dracoceph-alum heterophyllum benth. Several blood indexes of three groups were measured.The result showed that the RBC count of plateau-herb group was obviously lower than that of plateau group and the difference was significant (p<M0.05).Moreover, both the Hb mean and the Hct mean of plateau herb group were less than those of plateau. The result indexes that Dracocephalum heterophyllum Benth has certain protective effect on the hematopoietic system of the experiment rabbits in plateau.更多还原
