| 摘 要： | 用扫描电镜观察以甲基丙烯酸甲酯灌注鼠的肺微血管和肺泡。胸膜下毛细血管较稀疏,网孔粗大。毛细血管部分成锐角折返,亦可见毛细血管盲端。肺泡隔毛细血管均成扁平状膨大,且相互吻合成单层密集网。肺泡铸型为大小不等、不规则的多面体,表面可见肺泡Ⅱ型细胞核之压迹。两肺泡之间可见呈桥式连接的肺泡孔,亦可见部分呈三通管样相连。

| Abstract: | The pulmonary capillary vessels and alveoli of rats were injected by methyl methacrylate and investigated by means of a scanning electron microscope. The network of subpleural capillary was sparse and the holes of vascular rings were large. Some vessels turned back to be acute angles and some were observed as blind channels.The ne-twork of alveolar capillary enlarged flatly and fused together as a dense sheetlike network.The alveolar casts were polyhedrons and different in size and shape.There were markes of alveolar type cell in the surface of alveolar casts.The alveolar holes connected with two alveoli were like bridges or three-connectd tubes |
