Advancement of Puberty in the Female Rat by Estrogen

Endocrinology, 1965
Puberty, as defined by vaginal opening, ovulation and the initiation of estrous cycles, has been advanced more than a week in the immature female rat by treatment with low, approximately physiological dosages of estrogen (estradiol benzoate, 0.05 μg/100 g body wt/day). These results were achieved either by short-term treatment with estrogen starting at

Ganglioside lateralization in the brain of female rats

Journal of Neuroscience Research, 1997
The ganglioside composition of the cerebral hemispheres of young and adult rats of either sex has been herein assessed for the first time. In females, the total ganglioside content at any age, the content of GM1, GD1a, and GD1b at 8 days, and the content of GM1, GD1b, GT1b, and GQ1b at 60 days were higher in the right than in the left hemisphere.

Carbon tetrachloride hepatotoxicity in female rats

Experimental and Molecular Pathology, 1971
Abstract Intragastric administration of carbon tetrachloride to female rats induces rapid onset of peroxidative decomposition of lipids of the liver endoplasmic reticulum. The effect observed in female rats is indistinguishable from the same effect first observed in male rats.

Sudden bladder distention in a female rat

Lab Animal, 2005
We purchased a batch of 48 female Long-Evans rats, weighing 200–250 g, from an accredited animal supplier for studies on sexual behavior. The animals lived in groups of four in large wire-mesh cages in a colony room maintained on a reversed 12:12 h light/dark cycle at approximately 21o ± 2o C.

GABAergic Control of Receptivity in the Female Rat

Neuroendocrinology, 2008
GABAergic neurotransmission has been implicated in the control of the steroid-dependent behavior, lordosis. GABA has dual effects on lordosis: it facilitates lordosis through actions in the medial hypothalamus (mHYP) and it inhibits lordosis through actions in the preoptic area (POA).

Sexual reflexes in male and female rats

Neuroscience Letters, 1988
A novel preparation for the study of male and female sexual function in anesthetized, acutely spinalized rats is reported. In both sexes, the coitus reflex (the neuromuscular concomitants of sexual climax) could be elicited by mechanical stimulation of the distal urethra.

Receptivity of female rats.

Acta physiologica Academiae Scientiarum Hungaricae, 1979
Receptivity of female rats has been investigated under chronic experimental conditions. A receptivity index has been worked out for quantitative evaluation. It proved suitable for disclosing stimulatory (2.5 mg noretynodrel, oestradiol propionate) as well as inhibitory (etynodiol diacetate) effects. 2.5 mg noretynodrel has a biphasic effect; causing an

The pharmacokinetics of perfluorobutanoic acid in female rats

Environmental Pollution
Perfluorobutanoic acid (PFBA) is of increasing concern due to its widespread occurrence, high environmental mobility, and potential for human exposure. This study investigated the toxicokinetics of PFBA in female Sprague Dawley rats and assessed implications for human exposure. Under repeated oral exposure (0.2 mg/kg/day for 16 days), concentrations of

Effects of pinealectomy in the newborn female rat

American Journal of Anatomy, 1967
AbstractThat pinealectomy in the rat is followed by ovarian hypertrophy is an assumption which is rather widely accepted and which is fundamental to much contemporary pineal research. Nevertheless an analysis of the alleged supporting literature shows it to be surprisingly weak and limited to animals operated at three to four weeks of age.
