Brain membrane lipid in rats were analyzed after being fed either 30 or 100 ppm fluoride for 3, 5, and 7 months. The protein content of brain with fluorosis decreased, whereas the DNA content remained stable during the entire period of investigation. After 7 months of fluoride treatment, the total brain phospholipid content decreased by 10% and 20% in the(More)
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)
To determine whether phospholipid abnormality in Alzheimer's disease is associated with modification of phosphatidylethanolamine-N-methyltransferase, the activity of the enzyme was analysed in the frontal and occipital cortex of the brain from patients with Alzheimer's disease and from aged-matched control. The optimum pH for(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)
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)

65 cases of nerve root sheath cyst of lumbosacral region were found out of 544 cases of myelography, 43 were confirmed by operation. The main radiologic features were: round or oval in shape in 28 cases; cylindrical or fusiform in 14; and mixed form in 13. In 10 cases, the contrast medium was seen to extend in an irregular pattern along nerve root sheath.
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)
