Hypoglycemia sometimes occurs in patients with diabetes mellitus who receive excessive doses of insulin. Severe hypoglycemia has been known to induce mitochondrial swelling followed by neuronal death in the brain. Since L-carnitine effectively preserves mitochondrial function in various cells both in vitro and in vivo, we investigated its effects on the(More)
The pharmacological properties of AD-5423 [2-(4-ethyl-1-piper-azinyl)-4- (4-fluorophenyl)-5,6,7,8,9,10-hexahydrocycloocta[b]pyridine] were studied in biochemical and behavioral tests. In vitro, AD-5423 bound preferentially to dopamine (DA)-D2 (Ki, 14.8 nM; cf. haloperidol, 8.79 nM; and clozapine, 149 nM) and serotonin (5-HT)-S2 (Ki, 3.98 nM; cf.(More)
The effect of potassium ion and membrane potential on the uptake of L-glutamate in microvilli (brush border) vesicles prepared from human term placenta was studied using a rapid filtration technique. The uptake of L-glutamate into microvilli vesicles is Na+ electrochemical gradient dependent and pre-equilibration of the vesicles with K+ stimulates(More)
