A sensitive radioenzymatic procedure for the simultaneous determination of dihydroxymandelic acid, dihydroxyphenylglycol, and dihydroxyphenylacetic acid has been developed. The catechols were methylated by catechol-O-methyltransferase using S-adenosy

Summary The incubation of isolated medullary granules from cattle causes a spontaneous release of catecholamines along with equivalent amounts of ATP. The sympathomimetic amines : tyramine, phenylethylamine, amphetamine, methamphetamine, and ephedrin

Isolated hearts were perfused in vitro with Tyrode solution at 32°C. α-Methylnorepinephrine was found in the heart after infusion with α-Methylnora or α-methyldopamine, while the norepinephrine content of the heart remained unchanged. By infusion

On isolated electrically driven left atria (32°C, 1 Hz) and papillary muscles (37°C, 0.5 Hz) of the rabbit the mechanism underlying the positive inotropic action of dopamine was investigated. On both preparations the dose-response curve for dopamin

A radioenzymatic assay for determination of normetanephrine in blood plasma is described. It was based on N -methylation of normetanephrine by phenylethanolamine- N -methyltransferase using S -adenosyl[ methyl - 3 H]methionine as the methyl donor. 19
