[The catecholamine content of the mast cell system in rats exposed to a permanent magnetic field]

Influence of constant magnetic field (CMF-60 mT induction) on catecholamine content of the serous coats mast cell system was studied in 60 outbred albino rats by luminescent histochemical method. CMF exposition made twenty minutes daily during 70 days. Three days long one leaded to reduction of catecholamine content level in mast cell system. At the same time, CMF action from 6 to 10 days long caused increase of catecholamine level as compared to normal state in the structures studied. The data obtained were considered as a protective reaction of the organism, aimed to maintain the general homeostage balance.
