1. Nitric oxide (NO), peroxynitrite, formed from NO and superoxide anion, poly (ADP-ribole) synthetase have been implicated as mediators of neuronal damage following focal ischaemia. Here we have investigated the effects of n-acetylcysteine (NAC) treatment in Mongolian gerbils subjected to cerebral ischaemia. 2. Treatment of gerbils with NAC (20 mg kg(-1)(More)
NMDA receptors and Ca2+/calmodulin-dependent kinase II (CaMKII) have been reported to be highly concentrated in the postsynaptic density (PSD). Although the possibility that CaMKII in PSD might be associated with specific proteins has been put forward, the protein or proteins determining the targeting of the kinase in PSD have not yet been identified. Here(More)
A double methylazoxymethanol (MAM) intraperitoneal injection was prenatally administered to pregnant rats at gestational day 15 to induce developmental brain dysgeneses. Thirty adult rats from 8 different progenies were investigated with a combined electrophysiological and neuroanatomical analysis. The offspring of treated dams was characterized by(More)
Large evidence showing an association between depression and tobacco smoking is known. Nicotine is the active chemical responsible for smoking addiction, and its withdrawal may induce in smokers greater sensitivity to stress. Our aim has been to investigate the links between tobacco addiction and depression by studying the long-term effects of repeated(More)
The plant Hypericum perforatum is used in folk medicine to treat several diseases and research attention has been recently focused on its antidepressant action. Hypericin and flavonoids are the most important constituents of the plant, but the exact role of these compounds in the effects of hypericum on mood disorders is not well known. We have investigated(More)
The effect of adjunctive fluoxetine on negative schizophrenic symptoms was evaluated in 34 chronic schizophrenic in-patients on maintenance therapy with neuroleptics. They received randomly, on a double-blind basis, fluoxetine (20 mg/day) or placebo for 12 weeks. In the fluoxetine group, three patients dropped out because of side effects. Negative symptoms,(More)
BACKGROUND Small intestine permeability is frequently altered in inflammatory bowel disease and may be caused by the translocation of intestinal toxins through leaky small intestine tight junctions (TJ) and adherence (1,2). The role of hydrogen peroxide (H2O2), and nitric oxide (NO) and PARS in the permeability and structure of small intestine TJ is not(More)
Leptin administration inhibits diencephalic nitric oxide synthase (NOS) activity and increases brain serotonin (5-HT) metabolism in mice. We evaluated food intake, body-weight gain, diencephalic NOS activity, and diencephalic content of tryptophan (TRP), 5-HT, hydroxyindoleacetic acid (5-HIAA), and 5-HIAA/5-HT ratio after intracerebroventricular (ICV) or(More)
There is evidence that the excessive generation of reactive-oxygen radicals contributes to the brain injury associated with transient, cerebral ischemia. This study investigates the effects of tempol, a small, water-soluble molecule, that crosses biological membranes, on the brain injury caused by bilateral occlusion and reperfusion of both common carotid(More)
