Modification of reproductive function in the rat by 3-methylcholanthrene
Repeated exposure of adult female Wistar rats to 3-methylcholanthrene (MC) (25 mg kg-1 b.w., i.p., 2 x wk, 1 mo) was associated with a significant increase in estrus cycle length. In addition, an increased frequency of ...
Suppression of the acquisition of conditioned avoidance behavior in the rat by 3-methylcholanthrene
Repeated treatment with 3-methylcholanthrene (MC; 25 mg/kg body weight, IP, two times per week, 1 month) in both male and female Wistar rats resulted in decreased performance in two sessions of a two-way active avoidance ...
Effects of peripheral benzodiazepine receptor ligands on hypothalamic-pituitary-adrenal axis function in the rat
High concentrations of the 'peripheral' benzodiazepine (pBZD) binding site ('receptor') have been described in the hypothalamus, the pituitary and the adrenal glands. This study was undertaken to examine the effects of ...
Glucocorticoids inhibit estradiol-mediated uterine growth: Possible role of the uterine estradiol receptor
Stress-related activation of the hypothalamic-pituitary-adrenal axis (HPA) is associated with suppression of the reproductive axis. This effect has been explained by findings indicating that corticotropin-releasing hormone ...
Mechanisms of stress: A dynamic overview of hormonal and behavioral homeostasis
Environmental events, both physical and emotional, can produce stress reactions to widely varying degrees. Stress can affect many aspects of physiology, and levels of stress, emotional status, and means of coping with ...

Increased serum interleukin‐1bT during treatment of zhyperthyroidism with antithyroid drugs
Serum interleukin‐1bT (IL‐1bT) and soluble interleukin‐2 receptor (sIL‐2R) levels were examined in patients with hyperthyroidism due to Graves' disease (GD) and toxic nodular goitre (TNG) before and during antithyroid drug ...
Distribution of hippocampal mineralocorticoid and glucocorticoid receptor mRNA in a glucocorticoid resistant nonhuman primate
Glucocorticoids regulate the activity of the hypothalamic-pituitary- adrenal axis through both mineralocorticoid (MR) and glucocorticoid (GR) receptors in the hippocampus. In addition, glucocorticoids down-regulate hippocampal ...
The biobehavioral consequences of psychogenic stress in a small, social primate (Callithrix jacchus jacchus)
The biobehavioral consequences of psychogenic stress were examined using neuroendocrine and ethological methods in a captive colony of common marmosets (Callithrix jacchus jacchus). Specifically, hypothalamic-pituitary-adrenal ...
Effects of early parenting on growth and development in a small primate
We report here a study of the impact of caregiver-infant relationships on physical growth and behavioral development in a small primate, the common marmoset. Somatic growth was assessed from measurements of body weight, ...
