Reduced blood supply to the uterus as a cause for early embryonic death in the mouse

摘要: Limitation of blood supply to the developing embryo mouse was accomplished by electrocoagulation within vessels supplying one horn uterus. When blockage both uterine artery and vein secondary performed before mating, 35.6% ova, as represented corpora lutea (CL), were present implantation sites at autopsy, ten days post coitum (ten days); 91.1% ova (CL) on control side. During time between mating (average, 8.3 days), some reestablishment circulation had usually occurred. unilateral coagulation day five days, 2.6% 14.6% respectively, subsequently formed sites. When alternate branches coagulated day, 40.6% resulted in days. Tertiary arborizations undisturbed appear revascularize portions which been coagulated. ovarian, middle or cervical uterus blocked 6.3%, 42.9% 14.3% sites. It is suggested that ovarian portion critical descending embryo. There a significant correlation number all intact horns.
