| 摘 要： | 目的观察大鼠脑出血后不同时间点神经行为学和血肿周围脑组织病理学的特点。方法将成年SD大鼠随机分为假手术组和脑出血组;脑出血组大鼠通过立体定向术向脑内注入VII型胶原酶制成脑尾状核出血模型,并按不同时间点（1、3、7、14、28d）分为5个亚组。采用神经功能评分和HE染色分别观察脑出血大鼠神经行为学和脑组织形态学的改变。结果与假手术组相比,脑出血组大鼠的神经行为学评分3d时最明显3d与1、7d无明显差异（P〉0.05）;与14d和28d有显著差异（P〈0.05）]。脑出血后1d在尾壳核区域可见血肿形成,呈椭圆形或不规则形;3d时脑水肿明显;7d时血肿周围脑组织有胶质细胞增生;14d时血肿区逐渐形成不规则囊腔;28d时囊腔仍然存在,出血周边区见胶质细胞进一步增多。结论脑出血后神经行为学的改变、血肿及囊腔的形成与出血时间有关。

| Abstract: | Objective To observe the characteristics of neurological behavior and pathology of perihematoma region of rats following intracerebral hemorrhage.Methods The adult SD rats were randomly assigned into two groups:sham group and intracerebral hemorhage group.The rats of intracerebral hemorrhage group were dealed by stereotaxic method and injected Type VII collagen enzyme was injected into caudate nuclear of rats and they were subdivided into 5 subgroups according to various time(1 d,3 d,7 d,14 d and 28 d).Neur... |
