摘要: 应用免疫组织化学法进行动情周期和妊娠期BDF1雌性小鼠子宫内膜增殖细胞核抗原(proliferating cell nuclear antigen,PCNA)的染色反应。根据对不同时期子宫内膜各部位细胞增殖情况的观察,发现在动情期PCNA标记细胞数量最多,约占子宫内膜细胞总数的21.8%,并主要分布在子宫表面上皮中,约占表面上皮总数的60%.动情间期可见PCNA标记细胞的再次轻度增高,约占子宫内膜总数的9.4%,也主要分布在子宫表面上皮中,约占26%.妊娠期PCNA标记细胞主要以蜕膜上部为多,同时发现妊娠第9dPCNA标记细胞数量最多,约占细胞总数的14%.

Abstract: Sixty BDF1 female mice were divided into two groups: estrus cycle and pregnancy (day 4~10).The endometrium of mice were studied by immunohistochemistry.The proliferating cell nuclear antigen (PCNA) labelling index (%) was studied throughout estrus cycle and pregnancy.The results suggested that:①In estrus the number of PCNA labelling cells was the highest.These cells were 21.8% of all kinds of endometrium cells.They distributed mainly over superficial epithelium (60% of superficial epithelium).There was a slight increase of the PCNA cell in the disestrus (9.4% of all kinds of endoinetrium cells).They also distributed mainly over superficial epithelium (26% of superficial epithelium).②In pregnancy the PCNA labelling cell distributed mainly over upper decidua.They were the highest (14% ) in decidua of 9 th day of pregnancy.

Key words: PCNA cell, endometrium, immunohistochemistry
