Prostaglandins E and F in the uterine tissue of cyclic rats.
Prostaglandins E and F (PGE and PGF) levels and the biosynthetic ability of rat uterine tissue have been estimated in the various phases of oestrous cycle by radioimmunoassay technique. Significantly high PGF concentration was found during metaoestrous phase. In comparison, PGE levels did not show as high elevation. The metaoestrous phase also showed significantly higher biosynthesis of prostaglandins E and F. Our experimental findings support the role of prstaglandins in ovulation and luteolysis of the corpus luteum.
