포배가 자궁내막간질에 미치는 영향에 관한 실험적 연구
An Experimental Study on the Effect of the Blastocyst to the Endometrial Stroma
ABSTRACT
The present study was undertaken to investigate the developing mechanism and its biological significance of the decidua. Unilateral salpingeal ligation was performed on mature female Sprogue-Dawley rats. Mating was proceeded. On the 3rd, 5th, 7th, and 9th days of the pregnancy, morphological changes of both ligated (non-pregnant horn) and non-ligated (pregnant horn) salpinges were observed. Gradual change of the decidualization was observed already by the 5th day of the pregnancy in the non-ligated horn, but was not in ligated. Marked change of the decidualization was observed by the 7th and 9th days of pregnancy in the non-ligated horn, but little change was in the ligated. The results suggest that decidualization is contributed not only by endocrinological factors but also obviously by some factors of the blastocyst.
