There was BMP4 expression at E10 in epithelium of otic capsule. Later, BMP4 expressions were affluent in condensed mesenchyme, vestibular cartilage capsule and sense epithelium. 3. The expression pattern of Smad4 in vestibule is different from BMP4. It was not conspicuous until E15 that Smad4 expressed in macula and crista ampullaris and until E16 in periotic cartilage capsule.

BMP4从E10开始，在间充质浓聚前就有表达；间充质一开始浓聚，BMP4在其中就有较丰富的表达；早期主要表达在前庭囊及前庭囊周围的间充质，在胚胎发育的后期，其在软骨囊及前庭上皮里有广泛阳性表达。3。

In TPN group, some pathological alterations could be seen in jejunal mucosa epithelial cells on 14th post-operative day, such as mitochondrial edema, crista swelling, dilation of rough endoplasmic reticulum and nucleolus, and the appearance of abnormal substances in intercellular attachments. However, none of above these pathological changes could be seen in EN group.

在TPN组术后14d还观察到空肠粘膜上皮细胞内线粒体肿胀、脊变粗、粗面内质网和核仁肿胀，细胞紧密联结处出现异物沉淀等病理学改变，而EN组则无上述现象。

Objective To investigate in vitro interaction of Cryptococcus neoformans and human lung epithelial cells and to compare the interaction of different varieties of Cryptococcus neoformans.

目的研究新型隐球菌与肺泡上皮细胞的体外相互作用，探讨隐球菌肺部感染的发病机制。

结论活的隐球菌黏附与侵袭肺泡上皮细胞是隐球菌感染肺部的重要条件，不同变种对肺部的易感性可能不存在差异。

Results: The incidence of cryptorchidism of male offsprings in group C and D was 10.8% and 63.5% respectively. The organ/weight of cryptorchid testis and epididymis significantly decreased compared with the control. Abnormal pathological and micro-structural alternations of seminiferous epithelium and sertoli cells were also observed.

结果：C、D组雄仔鼠隐睾发生率为10.8%和63.5%；隐睾睾丸、附睾的脏器系数显著减轻；睾丸生精上皮萎缩，生精细胞层减少甚至消失，曲精小管体积减小；同时附睾管腔中精子缺如。
