LORDOSIS BEHAVIOUR IN MALE, FEMALE AND ANDROGENIZED FEMALE RATS

Journal of Endocrinology, 1976
SUMMARY Sex differences in the lordosis response of adult rats to ovarian hormones were studied in a series of experiments. Male rats were less sensitive to oestradiol benzoate (OB, a single injection of 10, 100 or 1000 μg/kg or seven daily injections of 2, 10 or 50 μg/kg) than were female rats.

Reproductive effects of hexachlorobenzene in female rats

Journal of Applied Toxicology, 2000
Hexachlorobenzene (HCB) is a polyhalogenated aromatic hydrocarbon widely distributed in the environment. In animal testing, HCB has been shown to be a reproductive toxin. Previous investigations of the effects of HCB on ovarian function have yielded equivocal results. Thus, the effects of chronic administration of HCB (1 g kg(-1) body wt.) on the ovary

Transplacental effect of diethylstilbestrol in female rats

Cancer Letters, 1979
The effect of diethylstilbestrol propionate (DES; 1 mg/kg body wt. was studied in the female offspring of rats exposed subcutaneously on the 19th day of gestation. Examination of vaginal smears showed persistent estrus in adult rats treated prenatally with DES.

Induced Hypersensitivity to Barbital in the Female Rat

Science, 1967
Female rats, treated with two daily anesthetic doses of barbital, exhibit 1 month later a significant increase in sleeping time over that of control animals. Hypersensitive animals, as compared to controls, show no alteration in liver weight (as percentage of body weight), but they manifest a significant shortening of time for induction of anesthesia ...

Sex and the female rat

Trends in Neurosciences, 2001
Dopamine release in the nucleus accumbens (NAcc) correlates with rewarding or reinforcing events, and has been studied extensively in the context of drug abuse, feeding, and sex. Using behavioral indicators and measurements of NAcc dopamine, it appears that sexual activity is rewarding for female rats only if they, rather then the males, are ...

Effects of weight cycling in female rats

Physiology & Behavior, 1989
Recent reports indicate that weight cycling (repeated periods of weight gain and loss) cause an organism to become an energy conserver, meaning that the organism gains weight more quickly and loses weight more slowly during subsequent weight cycles. The effects of weight cycling on rates of weight gain and loss, caloric efficiency, and ad lib wheel ...

The striated urethral sphincter in female rats

Anatomy and Embryology, 2003
The aim of this study was to give a microscopic description of the organization, the innervation and the slow or fast type of the striated fibers of the external urethral sphincter in the female rat. Conventional methods for photonic microscopy and immunochemistry were applied to cross and longitudinal sections of snap-frozen urethra.

Metabolism of Procymidone Derivatives in Female Rats

Journal of Agricultural and Food Chemistry, 2009
PCM-CH2OH [N-(3,5-dichlorophenyl)-1-hydroxymethyl-2-methylcyclopropane-1,2-dicarboximide] and PA-CH2OH [2-carboxyl-N-(3,5-dichlorophenyl)-1-hydroxymethyl-2-methylcyclopropane-1-carboxamide] are metabolites of the fungicide procymidone [N-(3,5-dichlorophenyl)-1,2-dimethylcyclopropane-1,2-dicarboximide] in rat.

Bone marrow in male and female rats

Experientia, 1978
Sex differences of high significance in the marrow weight relative to femur volume, as well as to body weight, were found in adult rats. A positive significant correlation was found between the femur volume and the marrow volume in both sexes, while a negative significant correlation between femur density and the marrow content (mg/mm3) exists only in ...

Chromium induced teratogenicity in female rat

Toxicology Letters, 1996
Exposure to chromium (VI) (250, 500 and 750 ppm as potassium dichromate) via drinking water pregestationally in rats revealed embryo- and fetotoxic effects in the form of a significant reduction in the number of implantations and number of fetuses. An increase in the number of resorptions, pre-implantation and post-implantation loss in chromium (VI ...
