Abstract

Histamine (HA) and tele-methylhistamine (t-MH) contents of the brain were assayed in the rats killed by various procedures. Microwave irradiation and freezing in liquid nitrogen caused a significant elevation of brain HA and we obtained evidence that the increased HA was from disintegrated mast cells outside of the brain. The method of near-freezing in liquid nitrogen proved to be most suitable for rapid cooling the brain when attempting to assay brain HA and t-MH.
