title: Compensation of the natural magnetic field does not alter N-acetyltransferase activity and melatonin content of rat pineal gland.
abstract: The aim of this study was to investigate if compensation of the natural magnetic field (NMF) influences pineal melatonin production. Rats were exposed to an artificial magnetic field (AMF) that compensated the NMF during the night for 30 min. In another experiment rats were treated with the beta-adrenergic agonist isoproterenol prior to treatment with the same AMF during the day. Pineal N-acetyltransferase activity was determined by a radioenzymatic assay and melatonin content was measured by radioimmunoassay. No statistically significant differences in these parameters were found in rats treated with this AMF when compared to control animals.
