【摘要】 为了观察模拟失重对血管内皮细胞（ＶＥＣ）的影响，对尾悬吊２ｌｄ大鼠的循环内皮细胞（ＣＥＣ）进行了检测。ＣＥＣ用免疫荧光方法鉴定。实验中发现悬吊组ＣＥＣ数量（４．５８±０．５４个／０(９μｌ）明显高于对照组（２．８０±０．８９个／０．９μｌ）（Ｐ＜０．００１），并且悬吊组有较多年轻细胞的脱落。提示模拟失重对血管内皮细胞有一定的损伤作用．更多还原

【Abstract】 In order to study the effects of simulated weightlessness on vascular endothelial cells(VEC).the numbers of circulating endothelial cells(CEC) were counted in rats after 21 d tail suspension. CECs were identified with fluoescein-labeled anti-human antibody to factor VIII related antigen.The results showed that numbers of CECs in tail-suspended rats were increased significantly as compared with thase in the control rats(P< 0.001).It suggested that stimulated weighlessness might be harmful to VEC.更多还原
