摘　　要：用HE、尼氏染色和Holmes银染法对长鬣蜥脑垂体的显微结构进行了观察。发现其脑垂体分腺垂体、神经垂体两部分,为背腹型。HE染色观察到腺垂体分为嗜酸性细胞、嗜碱性细胞和嫌色细胞3种类型,另外还观察到室管膜细胞和神经垂体内的垂体裂;尼氏染色显示神经垂体的赫令氏体以及排列致密的腺垂体中间部细胞;Holmes银染法显示神经垂体的无髓神经纤维、垂体门脉系统的血管。首次发现垂体裂与中脑视叶的水管系统相连通。These methods,including HE staining,Nissl staining,and Holmes silver staining,were employed to reveal the histological structure of each part of the hypophysis gland of the lizard,Physignathus cocincinus.There were two major portions in the hypophysis,the adenohypophysis and neurohypophysis.The hypophysis of the lizard belonged to the dorsal-pelvic type.Results of HE staining showed that the adenohypophysis cells could be divided into three types：eosinophilic cells,basophilic cells,and chromophobe cells.Additionally,the ependymal cells and the hypophysis cleft of neurohypophysis were also observed.Results of Nissl staining showed there were Herring body of neurohypophysis and the pars intermedia cells of adenohypophysis which were compactly arranged.Results of Holmes silver staining revealed the existence of the unmyelinated nerve fiber of neurohypophysis and the vascular of hypophyseal portal system.The connection of the hypophysis cleft with aqueduct in the optic lobe was first reported here.
