The present study is to culture otocyst cells in fetal, cochlear sensory epithelial cells of neonatal and mature respectively in vitro with refinement of culture media and techniques. Immunocytochemistry and Bromodeoxyuridine labeling are used to detect properties and mitotic status of cultured cells. With the observations about proliferation and differentiation in cultured cells, we want to find the origin of regenerative cells and to understand how these progenitors proliferate and differentiate.

Results Of the 11 cases, radical nephrectomy was done in eight, and partial in three; multilocular cystic RCC was confirmed in eight cases, unilocular cystic RCC in three. Histologically, clear cell carcinoma in nine cases, and Chromophobe carcinoma in two. All were followed for 3-61 months (27.9). Ten patients survived with tumorfree.

Purpose: 1. Zonular fibers are a specific form of extracellular matrix composed mainly of fibrillin what believed to be secreted by non-pigmented ciliary epithelium. The variation of fibrillin-1 distribution in lens capsule after zonule rupture was investigated in the research.

目的：1。晶状体悬韧带是一种特殊的细胞外基质，主要由睫状体非色素上皮细胞分泌产生的fibrillin-1（微纤维蛋白-1）所组成，本研究的目的是观察悬韧带离断后，晶状体囊膜中fibrillin-1的变化，探讨悬韧带离断对晶状体囊膜组成的影响；2。

Results With the expression in normal salivary gland as a standard, low C-erbB-2 mRNA expression was seen in adenolymphoma, basal cell adenoma. However, various degrees of over-expression of C-erbB-2 oncogene mRNA were detected in pleomorphic adenoma, mucoepidermoid carcinoma,acinic cell carcinoma ,adenoid cystic carcinoma ,papillary cystic carcinoma,and myoethelial cell carcinoma.

结果 正常涎腺和涎腺肿瘤中发现不同程度C-erbB-2mRNA的表达，以正常涎腺组织的表达水平为基准，在腺淋巴瘤、基底细胞腺瘤呈现低表达、无表达或与正常涎腺组织表达水平相似，多形性腺瘤、粘液表皮样癌、腺泡细胞癌、腺样囊性癌、乳头状囊腺癌和肌上皮癌则呈现不同程度的过表达。

Pox formation increased from 13.3%-20% to 33.3%-40% after passaging through 9 days old chicken embryo. Typical virus particles were observed under transmission electronic microscope in ultrathin sections of pathological tissues, allantochorion membrane of chicken embryos and affected cells.

用待检病料感染的BHK-21细胞培养物接种9日龄鸡胚绒毛尿囊膜，随着传代次数的增加，痘斑病变的出现率从13.3%~20%上升至33.3%~40%；用山羊痘病变皮肤、鸡胚绒毛尿囊膜和感染细胞进行超薄切片，在电子显微镜下可以观察到典型的山羊痘病毒粒子。

In fish and amphibia, the transition from maternal gene transcription to zygotic transcription happens during the time of midblastula formation, this stage is named by midblastula transition, at this period, embryo cell cycle composition changes, it is the first time to G1 time appearance, the cell cycle timelimit lengthens and the cell division synchronism loses, the large quantities of zygotic gene transcription starts.

鱼类和两栖类由母型调控向合子型调控过渡发生在中囊胚形成阶段，称为中囊胚过渡(midblastula transition，MBT)，胚胎细胞周期时相的组成在此期间发生变化，首次出现G1期，周期时限延长，细胞分裂的同步性丧失，大批合子型基因活化转录也在此时开始。
