Inhibition of menstrual uterine motility during water diuresis. 1978

E Cobo, and R Cifuentes, and M de Villamizar

Induced water diuresis blocks the central release of antidiuretic hormone (ADH) which is, in turn, supposed to play a role in the high uterine activity recorded during human menstruation. In order to further explore this possibility, uterine and antidiuretic activities were studied during water diuresis in 27 normal menstruating women, prior to the insertion of an intrauterine device. Shortly after the initiation of the water overload, simultaneous inhibition of both uterine and antidiuretic activities was obtained. Furthermore, the administration of ADH by intravenous infusion re-established the uterine motility to normal values while the administration of oxytocin did not. It is suggested that ADH has a direct role in the control of uterine activity during human menstruation.

UI MeSH Term Description Entries
D008598 Menstruation The periodic shedding of the ENDOMETRIUM and associated menstrual bleeding in the MENSTRUAL CYCLE of humans and primates. Menstruation is due to the decline in circulating PROGESTERONE, and occurs at the late LUTEAL PHASE when LUTEOLYSIS of the CORPUS LUTEUM takes place.
D010121 Oxytocin A nonapeptide hormone released from the neurohypophysis (PITUITARY GLAND, POSTERIOR). It differs from VASOPRESSIN by two amino acids at residues 3 and 8. Oxytocin acts on SMOOTH MUSCLE CELLS, such as causing UTERINE CONTRACTIONS and MILK EJECTION. Ocytocin,Pitocin,Syntocinon

D014599 Uterus The hollow thick-walled muscular organ in the female PELVIS. It consists of the fundus which is the site of EMBRYO IMPLANTATION and FETAL DEVELOPMENT. Beyond the isthmus at the perineal end of fundus, is CERVIX UTERI (the neck) opening into VAGINA. Beyond the isthmi at the upper abdominal end of fundus, are the FALLOPIAN TUBES.

D014667 Vasopressins Antidiuretic hormones released by the NEUROHYPOPHYSIS of all vertebrates (structure varies with species) to regulate water balance and OSMOLARITY. In general, vasopressin is a nonapeptide consisting of a six-amino-acid ring with a cysteine 1 to cysteine 6 disulfide bridge or an octapeptide containing a CYSTINE. All mammals have arginine vasopressin except the pig with a lysine at position 8. Vasopressin, a vasoconstrictor, acts on the KIDNEY COLLECTING DUCTS to increase water reabsorption, increase blood volume and blood pressure.
