... Imaging Corp., Downingtown, Pa., USA). Total numbers of ERα-ir neurons in each structure were counted and averaged. Mean blood glucose levels were analyzed by two-way ANOVA and Duncan’s multiple range test. Differences of p < 0.05 were considered significant. Estradiol benzoate Ovariectomy...

... elicited no change in ARH GK transcription, but decreased GK-ir in the rostral ARH. Acute NPH injection had no impact on GK gene profiles in estradiol benzoate (EB)- or oil-implanted ovariectomized (OVX) female rats, but diminished GK-ir cell counts in the OVX + EB caudal ARH. Precedent NPH treatment did...

... the photoperiodic modulation of female sexual behavior. Animals exposed to a nonstimulatory photoperiod were less behaviorally sensitive to treatment with estradiol benzoate (EB) alone, but did not differ from animals maintained under a stimulatory photoperiod when EB was combined with progesterone. The effect...

... period or longer. In contrast, infusion of 5.7 and 11.5 μ g EPIN/h had no effect on blood LH levels in unprimed rats. In OVX rats primed 3 days prior to infusion with 50 μ g estradiol benzoate and 25 mg progesterone (OEP), administration of CSF or the same doses of DA that previously inhibited episodic...

...-induced suppression did not show a decreased LH pulse amplitude. Rather, in control and metergoline-treated animals this parameter increased during stimulation, suggesting a buildup of readily releasable LHRH and/or pituitary LH. Lastly, estradiol benzoate suppressed pulsatile LH secretion but did...

..., was studied in ovariectomized (OVX) rats at different times of the day. The concentration of 5-HT and 5-HIAA and the total decline of 5-HIAA levels were higher in the morning than in the afternoon in OVX rats. Three days after the injection of 20 μg estradiol benzoate (EB), the concentration of 5-HT and its...

...K.P. Gunaga; A. Kawano; K.M.J. Menon The effect of an intraperitoneal injection of estradiol benzoate (EB) upon cyclic AMP accumulation in the hypothalamus of 21-day-old rats was studied. Clomiphene citrate administration prior to EB neutralized the estrogen-induced accumulation of hypothalamic...

... on these hormones of various doses (0.05–50 µ g) of estradiol benzoate (EB) given for 4 days was evaluated. Serum concentrations of LH were not significantly different in AF and males and were unchanged by any dose of EB; sex accessory organ weights in the males were reduced, however. Pituitary LH concentration...

...-induced hypoglycemia (IIH) and that adaptive modifications in transcriptional reactivity during recurring exposure are steroid dependent. ARH tissue was obtained by micropunch dissection from estradiol benzoate- and oil-implanted ovariectomized (OVX) rats that were treated by subcutaneous injection of one...

... to examine the hypothesis that this hormone regulates neural adaptability to recurring hypoglycemia. Groups of OVX rats were implanted with subcutaneous silastic capsules containing estradiol benzoate (E) or oil alone, and injected subcutaneously with one or four doses of the intermediate-acting insulin...
