A、C型子宫内膜种植窗期形态学特征

The morphological characters of pattern C and pattern A endometrium

目的:观察A、C型子宫内膜种植窗期形态学的特征。方法:选择自然周期尿LH峰日A、C型子宫内膜各10例。应用组织形态学方法和图像分析以及扫描电镜技术观察、分析组织形态变化及胞饮突特征。结果:①组织形态特征:C型子宫内膜的腺腔轻度增大,见核下空泡,A型子宫内膜的腺腔增大明显,腺腔内分泌旺盛;图像分析两组子宫内膜组织结构定量分析指标比较差异有显著性(P<0.05)。②扫描电镜:在120倍镜下观察,C型子宫内膜表面皱缩,较A型子宫内膜发育差;在2500倍镜下时,C型子宫内膜胞饮突发育滞后于A型子宫内膜。结论:晚卵泡期C型子宫内膜种植窗期内膜腺体发育和胞饮突发育均滞后于A型子宫内膜。

Objective： To observe the morphological characters of pattern C and pattern A endometrium. Methods： 10 samples of pattern C and pattern A endometriums in natural cycle LH （ ＋ ＋ ） days were chose. Organically morphological variation was observed and analyzed by organic morphology method and pietural analysis technology. Meanwhile, the pinopodes characters of endometrium were observed. Results： ①The characters of organic morphology： the glandular lumen of pattern C endometrium with empty bubbles slightly enlarged, the glandular lumen of pattern A endometrium obviously enlarged, and secretion was thrive in gland lumen. The ration analytic index of two groups of endometrium organised structures was different （ P 〈 0. 05 ）. ②Under SEM ： by 120 times observation, the facial development of pattern C endometrium was frown and the development was weaker than that of pattern A endometrium ; Under 2 500 times, the development of the pattern C endometrium＇s pinopodes was later than that of pattern C endometrium. Conclusion： The development of pattern C endometrium and endometrium＇s pinopodes are later than those of pattern C endometrium during window of the implantation at follicular phase. Possibly.
