Role of ovarian hormones on hoarding in rats--feedback mechanism.

Role of ovarian hormones in hoarding pattern.

Hoarding pattern studied in 28 adult female albino rats indicated cyclic changes in hoarding corresponding to alterations in estrus cycle. It was observed that the hoarding score was maximum at proestrus and the least at diestrus. Animals ovariectomised at proestrus maintained higher hoarding score and those ovariectomised at diestrus stablised on lower hoarding score. Progesterone administrati...

The Effect of Swimming Training on Serum Levels of Sex Hormones, Antioxidant Enzymes and Oxidative Damage of DNA Ovarian Tissue in Rats with Polycyclic Ovarian Syndrome

Background. Hormone disorders, stress-oxidative and inflammation in ovarian tissue cause no- ovulation in women with polycyclic ovarian syndrome (PCOS). Several studies have shown the role of exercises in control of sex hormones. Objectives. The aim of this study was to investigate the effect of 6 weeks of swimming training (ST) on serum levels of sex hormones, antioxidant enzymes and oxidativ...

Energetic challenges unmask the role of ovarian hormones in orchestrating ingestive and sex behaviors.

Effects of ovarian hormones on sex and ingestive behavior are well studied, and yet, their role in diverting attention from food to sex has not been examined directly, possibly because these functions are masked under conditions of excessive food abundance typical of the laboratory. Female Syrian hamsters were either fed ad libitum or food-restricted to 75% of their ad libitum intake for 8days ...

Can ovariectomy and learning affect prefrontal cortex GABAAα1 receptor distribution in passive avoidance model in rats?

Introduction: The interaction between steroid hormones and neurotransmitters such as GABA has been proved. The regulation of muscimol binding to high-affinity GABAA receptors by estradiol and progesterone has been studied within distinct brain regions using in vitro quantitative autoradiography. There are few studies about the mechanism of the effect of steroid hormones on behaviors such as ...
