PROSTAGLANDIN AND LEUKOTRIENE CONCENTRATION OF THE PERITONEAL-FLUID OF ENDOMETRIOSIS AND OTHER GYNECOLOGIC DISORDERS IN THE SECRETORY PHASE

In order to investigate whether prostanoids are involved in the pathophysiology of endometriosis, prostaglandin and leukotriene concentrations in peritoneal fluid were measured in adenomyosis, ovarian chocolate cyst and uterine leiomyoma. In the secretory phase, there was no significant difference in 6-keto PGF1α concentration in peritoneal fluid between the adenomyosis group and the leiomyoma group. TXB2 concentration did not significantly differ in the three study groups. Leukotriene C4 level in the adenomyosis group was significantly higher than that of leiomyoma in the secretory phase. Leukotriene B4 could not be detected by our assay system. Our results suggest that leukotriene C4 is possibly involved in the pathophysiology of endometriosis. © 1990.
