.... This role is associated with increased expression of astrocytic cystathionine-β-synthase (CBS), the key enzyme for H 2 S synthesis. However, it remains unclear whether H 2 S is mainly produced in astrocytes and contributes to the autoregulation of OT neurons. Methods: In hypothalamic slices of male rats, OT...

... stroke. In the present study, we hypothesized that exogenous melatonin may decrease hypoglycemia-induced neuronal death through the prevention of superoxide generation. To test our hypothesis, hypoglycemia was induced by injecting human insulin (10 U/kg, i.p.) in rats. Melatonin injection was started...

... for these studies is an accurate identification of the site(s) where Kiss1 transcription is initiated. Employing 5′-RACE PCR, we detected a transcription start site (TSS1) used by the hypothalamus of rats, mice, nonhuman primates and humans to initiate Kiss1 transcription. In rodents, an exon 1 encoding 5...

... (E 2 V) on brain and plasma β-endorphin (β-END) concentrations in gonadectomized rats of both sexes. Methods: Eight groups of female and 8 groups of male Wistar rats were included. For each sex, 1 group of gonad-intact and 1 group of gonadectomized rats were employed as controls (placebo). The other...

... these tissues express the leptin receptor mRNA by utilizing reverse-transcription polymerase chain reaction (RT-PCR) analysis in selected tissues from the male and female rat. The results revealed that the leptin receptor mRNA transcript is highly expressed in the ovary, uterus and testis, moderately expressed...

...Anna Maria Aloisi; Maria Emanuela Albonetti; Michela Muscettola; Fabio Facchinetti; Carolina Tanganelli; Giancarlo Carli The behavioral and immunoendocrine effects of formalin-induced pain were studied in male rats following a subcutaneous injection of formalin (50 µl; 0.1%, F01 groups, 10%, F10...

...Andreas Kjær; Ulrich Knigge; Hans Vilhardt; Jørgen Warberg Arginine vasopressin (AVP) appears to be involved in the histamine (HA)-and stress-induced prolactin (PRL) release. The present investigation was performed in male rats to clarify whether the role of AVP in HA- and restraint stress-induced...

.... Neurons in the lateral part of the BST were destroyed with bilateral injections of the cell-selective neurotoxin ibotenic acid (1.5 µg in 0.1 µl of solution per side). Two weeks later, the rats were stressed using an immobilization or conditioned stress paradigm. Rats with lesions in the lateral part...

...Delia M. Vázquez; Huda Akil The dynamics of pro-opiomelanocortin (POMC) biosynthesis in the adult rat are altered by demands imposed on the system, such that acute stress increases in the efficiency of anterior pituitary (AP) posttranslational events, while repeated stress increases...

... acute stressors, footshock and immobilization, in male Sprague-Dawley rats. Parameters measured were mean arterial pressure (MAP), heart rate (HR) and plasma levels of oxytocin (OT) and vasopressin (VP). Baseline MAP was elevated in the SAD group (≈25 mm Hg) and footshock stress increased arterial...

...Molly Carnes; Charles M. Barksdale; Ned H. Kalin; Mark S. Brownfield; Stephanie J. Lent To investigate the simultaneous effects of dexamethasone on peripheral and central adrenocorticotropic hormone (ACTH) systems, rats were treated with dexamethasone or saline for 4 days. Pituitary, plasma...

...William B. Wehrenberg; Roger Corder; Rolf C. Gaillard To test the hypothesis that neuropeptide Y(NPY) is involved in the regulation of the estrogen/progesterone-induced luteinizing hormone (LH) surge in ovariectomized rats, we passively immunized animals against NPY by administering purified...

... in adult male rats. Visual scoring of EEG records as well as spectral analysis revealed that CRF (0.0015–0.015 nmol) produced decreases in slow wave sleep concomitant with significant decreases in spectral power in lower frequencies (1–6 Hz) and increases in high frequencies (32–64 Hz). In contrast, GRF...

...William B. Wehrenberg Theeffects of a continuous infusion of growth hormone-releasing factor (GRF) on pulsatile growth hormone (GH) secretion were studied in conscious, freely moving rats. Male Sprague-Dawley rats were prepared with 2 indwelling venous catheters and were then housed individually...

...Jeffrey H. Glaser; Ronald J. Barfield The hypothesis that progesterone (P) activates estrous behavior in estrogen-primed female rats via a protein synthetic mechanism was examined. The protein synthesis inhibitor anisomycin was applied intracerebrally via 28-gauge bilateral implants to neural sites...

... in conscious rats. All the drugs were administered intracerebroventriculary, the antagonists 15 to 30 min prior to the agonists. The histamine-induced increase in serum corticosterone levels of stressed rats was considerably antagonized by prazosin, phenoxybenzamine, phentolamine and yohimbine, α 1 and α 2...

Groups of intact albino and black-eyed rats and albino animals with light-induced photoreceptor damage were studied in the dark period before, and after 15 and 30 min of exposure to either 0.0005, 0.175 or 3.33 µW/cm 2 irradiance of light. In animals with photoreceptor...
