摘要
给25只成年雌兔子宫内放置三种不同类型宫内节育器(IUD),6个月后,在检查IUD位置固定良好并有抗生育作用的基础上观察输卵管形态、分泌活动、肌肉活动及组织内Cu^(++)、PGs含量等变化。本文观察到兔子宫内放置金属单环、VCu200IUD及消炎痛VCu200IUD后输卵管组织内Cu^(++)含量均未明显增加;PGE/F比值呈上升趋势;峡部平滑肌收缩频率明显增加(P<0.05或0.01),未观察到紧张性阵发收缩波,粘膜皱襞完好,固有膜及乳头间质内可见不同程度充血、水肿及炎细胞浸润,上皮细胞内PAS阳性物质减弱,而分泌液葡萄糖含量无明显增减,结果表明兔子宫内放置惰性和活性IUD均能影响输卵管粘膜形态而输卵管肌肉活动及组织内Cu^(++)含量及分泌液中葡萄糖浓度则未发生明显变化。
Three types of intiauterine devices (IUDS) were placed in the uterus of 25 rabbits in this study. After 6 months, examination the lUDs were found in good position within the uterus and the efficacy of antifertility was good. The oviductal morphology) muscular, activity. Cu+ and PGs contents in the oviductal tissues were investigated. The results indicated that the Cu++ contents in oviductal tissue after SSR-IUD, VCu220 or indomethacin VCu20 IUD did not show any significant changes, but the PG EIF ratio tended to increases the contractile frequency of isthmic smooth musle increased markedly. The endometrial folds appeared intact. The basement membrane and the stroma exhibited congestion, edema and infiltration of the inflammatory cells. The PAS reaction of the epitelia became weaker and the glucose content in the oviductal fluid showed no change.
