  • Title: Prostaglandins F in uterine and ovarian compartments and in plasma from the uterine vein, ovarian artery and vein, and abdominal aorta of pseudopregnant rats with and without deciduomata.
    Author: Weems CW.
    Journal: Prostaglandins; 1979 Jun; 17(6):873-90. PubMed ID: 504693.
    Abstract:
    Prostaglandins F were measured in uterine and ovarian compartments and in uterine venous, ovarian arterial and venous and abdominal aorta plasma and the uptake of 3H-PGF2 alpha by ovarian compartments of 240 pseudopregnant rats with or without bilateral deciduomata in five experiments. Concentrations of PGF in deciduomal tissue, uterine venous plasma, ovarian arterial and venous plasma, corpora lutea, and remainder of the ovary and 3H-PGF2 alpha in the ovary were consistently as high or higher in pseudopregnant rats with deciduomata as in the endometrium, ovarian compartments, or samples of plasma from the same blood vessels of pseudopregnant rats without deciduomata. Levels of PGF were consistently 3 to 7 fold higher in uterine venous than in plasma from the abdominal aorta. It is concluded that extended luteal maintenance by deciduomal tissue is by some mechanism other than an inhibition of PGF synthesis by the uterus, transfer of PGF locally to the ovary, or uptake of PGF by the ovarian compartments.
