为研究育龄妇女输卵管上皮表面结构，应用扫描电镜观察１９例妇科手术取出的处于不同月经周期的输卵管。结果：增生早期，输卵管上皮纤毛细胞数较多，无纤毛细胞粘膜面多向管腔膨隆；增生中晚期，纤毛细胞数最丰富，无纤毛细胞表面多呈球形、半球形突向管腔，突起表面微绒毛极少；分泌早期，纤毛细胞数减少，无纤毛细胞表面略膨隆；分泌中晚期，纤毛细胞数明显减少，无纤毛细胞表面较平坦，微绒毛短而稀疏。提示：育龄妇女输卵管上皮细胞表面存在周期性变化 To study the surface structure of fallopian tube epithelium in women of childbearing age, the oviducts in different menstrual cycles from 19 gynecological surgeries were observed by scanning electron microscopy. Results: In the early stage of proliferation, the number of tubal epithelial epithelial cells was more than that of non-ciliated mucosa, and the most abundant ciliated cells in the middle and late proliferative phase. Most of the ciliated cells were spherical, In the early stage of secretion, the number of ciliated cells decreased and the surface of ciliated cells slightly bulbed. In the middle and late stages of secretion, the number of ciliated cells decreased significantly, and the surface of ciliated cells was relatively flat with short and sparse microvilli. Tip: women of childbearing age fallopian tube epithelial cell surface changes periodically
