Zona pellucida denudation, blastocyst proliferation and attachment in the rat.
The mode of zona pellucida denudation and blastocyst proliferation and attachment was investigated in Wistar rats during day 5 of pregnancy and in ovariectomized pregnant animals given 5-0 mg progesterone daily until the 10th day, when 0-2 mug oestradiol was injected together with progesterone. During day 5 of pregnancy, when only 5 empty zonae were detected from 32 animals, zona denudation occ...
متن کاملPlasma Progesterone, Blastocyst Steriodogenesis and Blastocyst Survival in Rats with Altered Thyroid Status
Studies in our laboratory continue to investigate the mechanism by means of which thyroid hormone influences reproductive physiology in the female rat. Thyroid hormone has been reported to exert effects upon the reproductive system and pregnancy in many types of animals, including human beings. These findings have been reviewed by Leathern (11). However, the mechanisms by means of which thyroid...
متن کاملComparison of tamoxifen effects on the actions of triiodothyronine or growth hormone in the ovariectomized-hypothyroid rat.
Recent studies have suggested that a subset of estrogen responses arise via modulation of triiodothyronine (T3) actions, and depend on T3 for expression: other estrogen responses are not T3-dependent. Moreover, tamoxifen acts as a full estrogen agonist in T3-dependent responses but behaves as an antiestrogen in T3-independent responses. T3 directly induces a variety of metabolic enzymes and pro...
متن کاملNavigation problems of ICSI or naive blastocyst can be solved with artificial blastocyst
Embryos have evolved a remarkable capacity to find implantation site. The impressive navigation ability of natural blastocysts may rely on highly sensitive signals arising from embryos and specialized signal processing strategies in the endometrium. Navigation capabilities may be compromised in ICSI embryos because of altered biochemical signaling. The design and delivery of artificial blastocy...
متن کاملThe Effect of Enoxaparin and Clopidogrel on Survival of Random Skin Flap in Rat Animal Model
BACKGROUND Necrosis of skin flaps is considered as an important complication in reconstructive surgery. We conducted an experimental study to investigate the efficacy of low-molecular weight heparin, clopidogrel and their combination to improve the flap survival. METHODS Forty male, adult Sprague-Dawlay rats were divided randomly into 4 groups. Standard rectangular, distally based dorsal ran...
