游蛇和沙蜥肺微血管铸型的比较观察

研究动物肺的微血管构筑情况，对于呼吸生理学和比较解剖学研究都有重要意义．Kemdall．Hajiya＆Okada，侯广棋和真炳攸等报道了人和鼠、犬等兽类肺微血管构筑情况，Duncher，West ＆ Bamford et al 研究了鸟类三级支气管和毛细血管的排列关系，刘代成等对家鸽肺毛细血管做了铸型观察，Smith ＆ Campbell，Smhh ＆ Rapson，Barrel ＆ Lamestchwandtner研究了爪蟾的肺微血管构筑及发育情况，笔者报道了川金丝猴和黄脊游蛇、菜花烙铁头、榆林沙蜥、麻蜥、花背蟾蜍等动物的肺微血管构筑情况，有关沙蜥肺微血管构筑与蛇类肺微血管的比较研究国内还未见报道，为了搞清沙蜥肺微血管构筑与游蛇肺微血管构筑的特点和差异，笔者对榆林沙蜥（Phrynocephalus frontalis Strauch）和虎斑游蛇（Rhabdophis tigrina lateralis）的肺微血管作了铸型扫描电镜观察．

Compare Observation on the Microvascular Casts of the Lungs of Rhabdophis tigrina lateralis and Phrynocephalus frontalis Strauch

The microvasculatures of the lungs of the Rhabdophis tigrina lateralis and the Phrynocephalus frontalis Strauch are studied by scanning electron microscopy using corrosion casts.The pulmonary microvascular anatomy is distinctly different in these two species.There were many reticular,secondary and third septa and alveolar septa on the inner surface of the lung wall of the Rhabdophis tigrina lateralis,which separated the inner surface of the lung wall into a lot of sac room,small room,subordinate small rooms...
