The effect of RCMF-magnetic therapy apparatus on signal substances was studied. The radioimmunoassay (RIA) suggested that the magnetic field increased p-endorphin markedly in plasma. ELISA indicated that the magnetic field inhibited vomiting reaction induced by chemotherapy drug, with reversible decrease of serotonin (5-HT) level in brains, small intestine tissue and serum. Furthermore, the bioeffect of magnetic fields on 5-HT level presented a typical window effect and post-effect, and the inhibitory effect of magnetic field on the emesis was parallel to the decrease level of 5-HT. This result implied that the decrease of 5-HT might be the basis of rotating constant magnetic field (RCMF) inhibiting drug-induced emesis. The nitric acid reductase-spec-trophotometry and nicotinamide adenine dinucleotide-diaphorase/arginine-vasopressin (AVP) cytochemistry technique showed that the magnetic field induced nitric oxide (NO) increase in hypo-thalamus and the high NO(A) level lasted for 3 hours.
