摘要
在兔仔胎龄23～25d行实验性膈疝于29d剖腹取得存活模型8例。同时取19～29d的正常兔胎仔20例。均行光镜检查其肺发育情况。实验性膈疝的肺发育组织形态学显示中央发育较快而周围成熟迟缓。
Experimental diahragmatio hernia was created on fetal rabbits during gestaional day (GD) 23-25d, and 8 rases of the model survived in intrauterin'j life up to the full term -were obtained by hysterotomy for morphologic study on pulmonary hypoplsia. At the samatime 20 normal f^tal rabbits on 19-23d were studied for pulmonary development in scries. Four stages of normal fetal lung development, such as pseudoglandular period (19-23d), canalicular period (23-25d), sacular period (25-28d), and alveolar period (28-23d) were demonstrated. While in the experimental models, the pulmonary development were hindered in various. degrees related to the onset of diaphragmatic hernia on GD, and the extent of compression by herniated intra-abdominal organ
