本研究观察了家兔妊娠早期（1-4天）输卵管不同部位（伞部、漏斗部、壶腹和峡部）的组织形态学变化。据观察，分泌细胞（PAS阳性细胞）的数量减少，在前4天的怀孕期间的伞与非分泌细胞（PAS阴性细胞）的数量相应增加。与此相反，有PAS阳性细胞在峡部在怀孕早期的数量增加。在漏斗部和壶腹中，PAS阳性细胞的数量在第3天增加。一个显着的下降，上皮细胞的高度观察到在菌毛在妊娠早期。相反，在怀孕的前3天，在峡部观察到该参数的显着增加。在漏斗部的上皮细胞的高度略有下降，观察到怀孕的第4天，而在壶腹部，它是显着增加的第1和第3天。总体结果表明，在妊娠早期，兔输卵管不同区域的组织形态学特征存在选择性改变。
In this study, we determined the histomorphological changes in different regions of the oviduct (fimbriae, infundibulum, ampullae and isthmus) during early pregnancy (days 1-4) of the rabbit. It was observed that the number of secretory cells (PAS-positive cells) diminished in the fimbriae during the first 4 days of pregnancy with the corresponding increase in the number of non-secretory cells (PAS-negative cells). In contrast, there was an increase in the number of PAS-positive cells in the isthmus during early pregnancy. In both the infundibulum and the ampullae the number of PAS-positive cells was increased on day 3. A significant decrease in the height of the epithelium was observed in the fimbriae during early pregnancy. On the contrary, a significant increase in this parameter was observed in the isthmus during the first 3 days of pregnancy. A slight decrease in the height of the epithelium was observed in the infundibulum on day 4 of pregnancy, while in the ampullae it was significantly increased on days 1 and 3. The overall results indicate that during early pregnancy there is a selective modification in the histomorphological characteristics of the different regions of the rabbit oviduct.
