摘　　要：用血管铸型和扫描电镜技术对绵羊肺胸膜下的微血管构筑特征进行观察.结果显示:胸膜面有两层微血管网分布,大部分视野仅见胸膜下微血管网,但局部区域在胸膜下微血管网的表面还匍匐有一层稀疏的微血管网;胸膜下微血管网按照微动脉、终末微动脉、毛细血管前微动脉和毛细血管的形式分支构成,微动脉和终末微动脉的铸型表面可见明显的环状缢痕;小叶间隔内分布的微血管与胸膜面浅层的微血管相互移行.绵羊肺胸膜下微血管的构筑特征与新生牦牛和双峰驼相近,但与文献报道中对人和犬、猴、兔、鼠等动物的描述差别较大.The present study characterized the subpleural pulmonary microvascular architecture of sheep by vascular corrosion cast and scanning electron microscopy.Results show that two-layered vascular networks are found on the pleura,and the subpleural vascular networks are found in most observed areas,while the sparse vascular network overlaid onto the subpleural network in some areas.The subpleural microvascular network is mainly branched by the arteriole,terminal arteriole,precapillary arteriole and capillary in order.The obvious circular imprints are found on the arteriole and terminal arteriole cast surface.The interlobular microvessels and the superficial pleural microvessels are transitional.The subpleural pulmonary microvascular architecture of sheep is similar to that of newborn yak and bactrian camel,but there are the significant differences between sheep and human,canine,monkey,rabbit and rat.
