摘要(Abstract)：
为了解两栖动物中华大蟾蜍(Bufo gargarizans)视网膜中神经胶质细胞形态结构及分布,利用生物显微技术、投射电镜技术和免疫组化技术显示了中华大蟾蜍视网膜胶质细胞形态结构。观察结果显示,中华大蟾蜍视网膜中仅分布有Müller细胞。光镜下Müller细胞在视网膜中成单层分布,细胞长轴沿着眼球半径成放射状排列,胞体位于内核层,胞体发出至少2个主干突起。电镜下视网膜Müller细胞的胞质及胞核着色较周围细胞深,细胞内有明显的纤维成分,与其他神经成分易于区别。Müller细胞近巩膜侧的主干突起延伸到视杆与视锥细胞的内节与胞核交界处,并彼此相互连接形成外界膜,近玻璃体侧的突起末端形成圆锥形的终足,锥形的底部紧邻玻璃体,且在此处彼此相互连接形成内界膜。
