Measurements of calcium uptake and cyclic GMP production by cerebellar granule cells grown in primary culture demonstrated that ethanol preferentially inhibited N-methyl-D-aspartate (NMDA) receptor-gated cation channel function. Concentrations of ethanol as low as 10 mM inhibited NMDA-stimulated Ca2+ uptake by greater than 30%, and ethanol also inhibited(More)
Cessation of chronic ethanol administration, and elimination of ethanol from the body, results in a withdrawal syndrome in mice characterized by behavioural symptoms and hypothermia. During withdrawal, the accumulation rate of [14C] 5-hydroxytryptamine (5-HT) from [14C]tryptophan, was significantly lower in the brainstem of the ethanol-withdrawn animals(More)
As part of a study of the effects of lithium carbonate on neurochemical function in man, platelet and lymphocyte adenylate cyclase activity and lymphocyte beta-adrenergic receptor binding characteristics were determined before and after 2 weeks of lithium treatment in 10 normal volunteers. Lithium had differential effects on platelet and lymphocyte(More)
BACKGROUND The current Ebola outbreak has proved devastating to vulnerable populations in West Africa. Health needs assessments were conducted in two districts of Sierra Leone to identify and quantify the impact of the outbreak on population health and health systems. METHODS Mixed qualitative and quantitative methods were employed including interviews,(More)
In primary cultures of cerebellar granule cells of the rat, the accumulation of cyclic GMP was stimulated by glutamate, acting at the N-methyl-D-aspartate recognition site, and by atrial natriuretic factor. The response to glutamate was calcium-dependent, while the response to atrial natriuretic factor was not. Ethanol inhibited the accumulation of cyclic(More)
Phosphatidylinositol 4,5-bisphosphate (PIP2) breakdown was stimulated by agonists acting at muscarinic cholinergic and alpha 1-adrenergic receptors in mouse brain. Ethanol, in vitro, inhibited basal cerebral cortical PIP2 breakdown with a threshold concentration of 75-100 mM. Basal PIP2 breakdown in hippocampus and striatum was less sensitive to ethanol.
