摘要
实验用甲苯胺蓝染色法,对64例中性甲醛固定的健康妇女输卵管肥大细胞的数量和分布进行了观察.结果表明,肥大细胞主要分布在输卵管肌层;粘膜层和外膜中较少(P<0.01).宫内放置节育环的妇女,输卵管肥大细胞数量比哺乳闭经期多(P<0.05),但和月经周期的增生期,分泌期及妊娠期比较,均无显著们差异(P>0.05).结果提示,人输卵管肥大细胞的数量并不受宫内节育环、妊娠和月约周期的影响.因此,肥大细胞可能参与输卵管血流量、血管通透性和平滑肌运动的调节.
The number and distribution of mast cells in the oviducts of 64 healthy women wereinvestigated after they were fixed in 4% neutral buffered formaldehyde and stained with toluidineblue. The results indicated that the mast cells in the oviduct were mainly distributed in the muscular layer, and were comparatively less in the lamina propria and the serosa (P<0.01). The mastcell concentration was higher in women using an intrauterine contraceptive device (IUCD) than thatin bresat feeding peroid (P<0.05), but there was no statistical difference when it was comparedwith that in pregnancy proliferative phase or secretory phase of menstrual cycle (P>0.05). Thesefindings suggest that the insertion of intrauterine contraceptive device, normal menstrual cycle andpregnancy have no effects on human oviduct mast cell count. Therefore it is reasonable to assumethat mast cells may play a role in the regulation of vascular permeability, muscular dynamics, andthe volume of blood flow in the oviduct.
