A method for the quantitation of L-glutamic acid in the picomole range was developed by finding conditions which allowed the production of NADH by the action of the L-glutamate dehydrogenase (EC 1.4.1.3) and its subsequent transformation to a highly fluorescent derivative. The method measures linearly glutamate from 250 pmol to 5 nmol. For its simplicity(More)
The glutamate decarboxylase activity in the rat cerebellum, frontal cerebral cortex, hypothalamus, substantia nigra and nucleus caudatus, was measured after either acute or chronic administration of (+)-amphetamine (1.35 and 5.4 mg/kg, i.p.). It was found that following 45 days of treatment the highest dose of the drug induced a selective increase of(More)
