摘　　要：目的　观察鼠壁胸膜间皮孔的形态结构 ,阐明胸膜腔内物质的吸收途径。方法　向大鼠胸膜腔内注射示踪剂 ,应用扫描电镜方法观察壁胸膜间皮的形态变化。结果　壁胸膜表面覆盖一层连续的间皮细胞 ,其按形态可分为立方形和扁平形两种 ,细胞表面覆盖大量的微绒毛 ,在立方形间皮区可见间皮孔。Objective To explain the routes of absorbing particulates in the pleural cavity by observing the morphosis structure of the mesothelial stomata.Methods The morphosis of the mesothelium of the parietal pleura in rat were investigated by intrapleura injection with tracers and observed by scanning electron microscope.Results The mesothelial cells lining the parietal pleura appeared as both cuboidal and flattened cell bodies.The microvillus were well developed in the cell surface.The mesothelial stomata were observed in the cuboidal-cell regions of the mesothelium.Conclusion The mesothelial stomata of the parietal pleura play an important role in the pleural cavity.
