Prostaglandins, leukotrienes, and medicine

Endogenous prostaglandin (PG) concentrations (6oxo PGF1 alpha, PGE, PGF2 alpha) have been measured by radioimmunoassay in the endometrium of women with objectively assessed menstrual blood loss (MBL). The concentration of PGE and "total" PG…

In order to investigate prostacyclin production by human myometrium, uterine cervix and leiomyoma, slices of each tissue were incubated. The 6-keto prostaglandin F1 alpha concentration of the incubation medium was measured by radioimmunoass…

The levels of 11-deoxy-13,14-dihydro-15-keto-11 beta, 16 xi-cyclo PGE2 (bicyclo PGEM), 13,14-dihydro-15-keto PGF 2 alpha (PGFM), cortisol and prolactin were measured by radioimmunoassays in five serial plasma samples collected from fourteen…

Prostaglandin release by leiomyomas obtained throughout the menstrual cycle was examined using a superfusion technique. The principal prostaglandin produced was 6-keto-PGF1 alpha, with PGF2 alpha and PGE2 in lesser amounts. No cyclical chan…

The interaction between the prostaglandin production of the human endometrium and myometrium has been further investigated using intact pieces of endometrium in homogenates of myometrium. There was an increase in the production of 6 oxo PGF…

In two independent studies, ibuprofen and naproxen sodium were found to be equi-effective in alleviating dysmenorrheic symptoms. However, the effects of these drugs on menstrual PG release were found to be dissimilar. Ibuprofen primarily in…

A randomized double-blind cross-over study was carried out in 19 young female undergraduates with severe primary dysmenorrhea to compare the efficacy and tolerance of treatment with diflunisal and naproxen. All patients received both substa…

In this study we have obtained endometrium and myometrium from women whose menstrual blood loss had been measured objectively. Samples of tissue were snap frozen in liquid nitrogen for the estimation of PG content and tissue was homogenized…
