title: Pulsed static magnetic field effects on in-vitro pineal indoleamine metabolism.
abstract: In-vitro rat pineal glands stimulated with the beta-adrenergic receptor agonist isoproterenol to induce melatonin synthesis and exposed for 1 h to a pulsed 0.4-G static magnetic field demonstrated significant inhibition of serotonin-N-acetyltransferase activity and melatonin content. 2-h exposure to pulsed magnetic field also resulted in a significant reduction in isoproterenol-induced serotonin-N-acetyltransferase activity. These results support the idea that the cultured pineal gland can be affected directly by artificially generated weak magnetic fields.
