摘要
目的 观察实验性脑出血血肿周围组织的细胞凋亡情况。方法 采用犬脑内注入非肝素化的自体动脉血建立实验性脑出血动物模型。分别在术后 6 h、2 4 h、4 8h、72 h和 7d处死动物 ,取脑 ,制成单细胞悬液 ,流式细胞仪检测凋亡细胞的百分率。结果 注血后实验动物有类似于自发性脑出血的行为变化 ,大体和光镜下符合脑出血后的病理改变。血肿形成后上述各时间点凋亡细胞所占百分率分别为 :9.6 9%、15 .4 7%、2 5 .6 7%、2 9.0 6 %和37.4 6 %。结论 犬脑内注入非肝素化的自体动脉血可建立实验性脑出血的动物模型。血肿形成后 6 h即可检测到凋亡细胞的存在 ,血肿周围组织中凋亡细胞所占的比例在 7d内随时间延长逐渐增加。
