The results showed that the inhibiting action of the indomethacin releasing copper IUD (FICu IUD) on the PGI 2 was stronger than that on the TXA 2, the ratio of 6 keto PGF 1α /TXB 2 was reduced with the increase of the doses. There were significant differences between the groups. The FICu IUD could inhibit the rising of the ET level and lighten the endometrial impairment caused by the FCu IUD, and promote copper ion release. It was suggested that indomethacin released by FICu IUD could effectively reduce abnormal uterine bleeding.展开更多
