Antidepressants are reported to display anti-inflammatory effects. Nitric oxide (NO), in turn, has a key role in inflammation. The objective of the present study was to evaluate the effect of amitriptyline co-administered with L-NAME (a NO synthase inhibitor) on certain parameters of acute inflammatory response in rats, as a form to investigate a possible(More)
The present study was designed to evaluate the effects of cohabitation for 11 days with a sick conspecific on hypothalamic levels and turnover of noradrenaline NA (experiment 1) and on neutrophil oxidative burst and phagocytosis in mice (experiment 2). Female mice were divided into two groups: control and experimental. One mouse of each control pair was(More)
This study was undertaken to evaluate the acute effects of single low doses of melatonin given to healthy volunteers in the evening. Six healthy male volunteers (age range 22-24 years) participated in this study, after signing an informed consent form. They received in a double-blind fashion placebo or 0.3 or 1.0 mg melatonin at three fixed times: 18:00,(More)
Cohabitation for 14 days with an Ehrlich tumor-bearing mice was shown, among others, to increase locomotor activity, and hypothalamic noradrenaline levels and turnover, to decrease the innate immune responses and animal resistance to tumor growth. The present experiment was designed to access the relevance of tactile, olfactory, and visual communication to(More)
The present study was designed to evaluate the effects of mice cohabitation with a sick conspecific cage mate on peritoneal macrophage activity and on resistance to Ehrlich tumor growth. Female mice housed in pairs were divided into control and experimental groups. One mouse of each control pair was inoculated with NaCl (0.1 ml/10 g) intraperitoneally and(More)
BACKGROUND/AIMS Antidepressants are reported to exhibit antiinflammatory effects. However, mechanisms involved in this action have not been elucidated. Thus, the objectives of the present study were (a) to evaluate the effects of amitriptyline on the acute inflammatory process, and (b) to investigate the participation of α(1)-adrenergic receptors and(More)
