...Jeffrey H. Glaser; Ronald J. Barfield The hypothesis that progesterone (P) activates estrous behavior in estrogen-primed female rats via a protein synthetic mechanism was examined. The protein synthesis inhibitor anisomycin was applied intracerebrally via 28-gauge bilateral implants to neural sites...

...Beverly S. Rubin; Ronald J. Barfield The present experiment was designed to determine whether sequential replacement of estrogen and progesterone to the ventromedial hypothalamus (VMH) would be sufficient to induce estrous behavior in ovariectomized rats. Bilateral cannulae containing 17β-estradiol...

...Susan D. Dudley; Israel Ramirez; George N. Wade Chronic insulin deficiency, produced by administration of 60 mg/kg streptozotocin, leads to reduced estrous behavior and lower estradiol uptake in both whole homogenate and cell nuclear fractions of hypothalamus-preoptic area and pituitary gland...

...L.A. Ciaccio; R.D. Lisk Following a period of estrogen priming, the spayeds hamster displays normal estrous behavior within 2–3 h after subcutaneous placement of progesterone. To determine the locus of the estrogen priming effect, a single midline implant of estradiol, fused within the lumen...
