Ghrelin, an orexigenic brain-gut hormone promoting feeding and regulating energy metabolism in human and rodents, was reported to enhance both adult neurogenesis and hippocampus-dependent memory formation. However, it is still unclear whether ghrelin-induced hippocampus neurogenesis is responsible for its memory improvement. Using 5-bromo-2' deoxyuridien(More)
Ghrelin is an orexigenic brain-gut hormone promoting feeding and regulating energy metabolism in human and rodents. An increasing number of studies have reported that ghrelin and its identified receptor, the growth hormone secretagogue receptor 1a (GHS-R1a), produces remarkably wide and complex functions and biological effects on specific populations of(More)
The effects of L-sulpiride and SCH 23390 on ethanol-induced striatal ascorbic acid (AA) release in normal and 6-hydroxydopamine-lesioned rats were studied by using microdialysis coupled to high performance liquid chromatography with electrochemical detection. Ethanol (3.0 g/kg i.p.) significantly stimulated striatal AA release by 200% above the baseline in(More)
Ghrelin and nesfatin-1 are two recently discovered peptide hormones that play opposite roles in the food intake, body-weight control and energy homeostasis in both human and rodents. Beyond its appetite-control function, increasing evidence has shown that ghrelin affects multiple advanced activities in the central nervous system, including memory and(More)
Antipsychotic drugs were initially considered to act predominantly through their antagonism at dopamine D(2)-like receptors. However, reports have demonstrated that the typical neuroleptic drug haloperidol and the atypical neuroleptic drug clozapine showed differential actions in clinical, behavioral and biochemical studies. Since ascorbic acid has a(More)
