Sodium ion concentrations in uterine flushings from "implanting" and "delayed implanting" mice. 1983

L J Van Winkle, and A L Campione, and D P Webster

The uteri of mice were flushed with isotonic mannitol (1) on the day of implantation during normal pregnancy or (2) during delay of implantation. The Na+ concentration in flushings was reduced during diapause but had increased by 65% 24 h after progesterone-treated ovariectomized mice received estrogen injections. The results suggest that the apparent metabolic quiescence of diapausing blastocysts may, in part, be a consequence of lower (Na+) in the uterus during delay of implantation.

D010065	Embryo Implantation, Delayed	Delay in the attachment and implantation of BLASTOCYST to the uterine ENDOMETRIUM. The blastocyst remains unattached beyond the normal duration thus delaying embryonic development.

D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D011374	Progesterone	The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.

D005260	Female		Females
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

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.
