It is now proven that RC-stressed mice exhibit tolerance to LPS, we examined thermal responses to LPS challenge in RC-stressed mice by monitoring core...

Thiorphan and DALA, administered centrally (4 µg i.c.v./rat) or peripherally (400 µg/kg), induced a significant gastric protection. Prior treatment with naloxone s.c. (1...

...Hakan Tıkız; Neşe Tunçel; Firdevs Gürer; Cengiz Baycu Various stressful stimuli cause mast cell degranulation. Hemorrhagic shock is one such stressful stimulus which may cause mast cell degranulation and histamine release. Histamine may be involved in the pathophysiology of hemorrhage...

... and chronic defeat stress in male mice aged 6 weeks, 7 months and 1 year. Specific uptake in 6-week-old mice was increased from control values only in the cerebellum following acute but not chronic stress. Specific uptake in the cortex and hypothalamus was unchanged from control values following both acute...

...B.H. Ali The protective effect of dimethylsulphoxide (DMSO) against stress- and indo-metacin-induced gastrointestinal ulcers was assessed in rats. It was found that stress (restraint at 4 ° C for 3 h) produced mucosal lesions in the stomach antrum and corpus, and the small intestine. DMSO given...

...Gary B. Glavin Rats were starved for 24 h. Morphine sulphate (1.0, 2.0 or 4.0 mg/kg i.p.) or naloxone-HCl (12.5, 25 or 50 mg/kg i.p.) was administered prior to 3 h of cold-restraint stress. Morphine at 4.0 mg/kg significantly reduced the ulcer severity relative to saline-injected controls...

...A. Armario; L. Campmany; J. Hidalgo The present experiment was undertaken to study the metabolic response to stress of single or chronic ACTH-treated male rats. It was found that chronic ACTH-treated rats showed a slight reduction in food intake and a decrease in body weight gain. This treatment...

...Soter Dai; Mo-Yin Chan In rats subjected to restraint and exposure to cold, naloxone did not significantly influence the increased serum concentrations of corticosterone or the incidence of stress ulceration, but it significantly reduced the severity of gastric lesions. These findings suggest...

... placed under either stress or when they were treated with ETOH and stress simultaneously. The adrenalectomized rats showed a similar response when they were treated with ETOH and DXM simultaneously. The liver TG levels were significantly different from control in all treated animals. The ETOH-treated...

...Ottorino Fanelli; Francesco Tenuta A cardiac stress was performed in the isolated perfused rabbit heart by means of four injections of 0.5 µg epinephrine in the coronary vessels. The endogenous (–)carnitine/acetyl(–)carnitine ratio was also determined. The two exogenous optical isomers of carnitine...
