本研究采用14只成年和幼年家兔的各节脊髓,作脊髓灰质分层研究。所用的脊髓切片为80μm、60μm和15μm的横或矢状切片以及2μm的半薄切片。对细胞体和髓鞘染色分别采用甲苯胺蓝、坚牢焦油紫、LuXol Fast Blue及对苯二胺。此外,还用显示...本研究采用14只成年和幼年家兔的各节脊髓,作脊髓灰质分层研究。所用的脊髓切片为80μm、60μm和15μm的横或矢状切片以及2μm的半薄切片。对细胞体和髓鞘染色分别采用甲苯胺蓝、坚牢焦油紫、LuXol Fast Blue及对苯二胺。此外,还用显示灰质乙酰胆碱酯酶活性的方法协助分层研究。分层研究是根据Rexed对猫脊髓灰质分层的原则。研究结果发现家兔脊髓分层基本类似于猫,但在各层的范围及结构方面仍有一定不同。展开更多
