Pineal and Hypophyseal Responses to Selenium Treatments in Light Deprived Adult Female Wistar Rats

Role of Bradykinin and Mas Receptor Blockade in Renal Vascular Responses to Angiotensin 1-7 in Adult Female Rats

Background and purpose: Chronic kidney disease is among the common diseases in the world. Studies show that women are more protected against renal diseases compared to men. On the other hand, vasodilatory axises of renin angiotensin system (angiotensin 1-7 (Ang 1-7)- Mas receptor (MasR)), kallikrein-kinin, and nitric oxide (NO) play key roles in kidney function and circulation in females. There...

Interactions of the pineal and exposure to continuous light on organ weights of female rats.

Either exposure to constant light for 80 days or pinealectomy produced similar changes in the weights of the ovaries and adrenals of female rats. These were not additive when both procedures were employed. Pinealectomy did not share with light-exposure the capacity to induce uterine hypertrophy. Rats exposed to constant light for 56 days had lighter pineals than animals kept in darkness; this d...

The Perinatal Effects of Lithium Carbonate on Hypothalamic-Pituitary-Gonadal in Adult Female Wistar Rats

Background & Objectives: Lithium is the metal used in bipolar disorder treatment.  As for the prevalence of the disorder infertility (childbearing) age and the use of lithium, this study aimed at studying the effects of drugs on histological changes, and the ovarian function in the first generation of adult female offspring was performed. Materials & Methods: In this experimental study, 40 pre...

Change in body weight and composition of adult nongravid female rats deprived of dietary protein.

Affective and adrenocorticotrophic responses to photoperiod in Wistar rats.

The present study tested the hypothesis that seasonal intervals of exposure to modest changes in photoperiod, typical of those experienced by humans living in temperate latitudes (10-14 h light/day), engage changes in emotional behaviour of Wistar rats, a commonly-used animal model for investigations of affective physiology. Short day lengths (<or= 12 h light/day) induced behavioural despair in...

Wistar-Kyoto Female Rats Are More Susceptible to Develop Sugar Binging: A Comparison with Wistar Rats

The hedonic component of the feeding behavior involves the mesolimbic reward system and resembles addictions. Nowadays, the excessive consumption of sucrose is considered addictive. The Wistar-Kyoto (WKY) rat strain is prone to develop anxiety and addiction-like behavior; nevertheless, a lack of information regarding their vulnerability to develop sugar binging-like behavior (SBLB) and how it a...
