THE REACTION AMINE CONTAINING STRUCTURES OF THYMUS ON THE INTRODUCTION OF MELATONIN AT DIFFERENT CONDITIONS OF LIGHTING
The experimental animals were given melatonin in dose of 0,03 mg per day under different conditions of lighting (by daylight and artificial darkening). The content of neuromediators in the structures of the thymus was determined using luminescent-histochemical methods of Falk and Cross. The research showed that the introduction of melaxen leads to a redistribution of biogenic amines in the structures of the thymus. The long introduction of melatonin by artificial darkening it has an immune stimulating influence which is confirmed by increase in the concentration of catecholamines and decrease of serotonin. It was noted that differ serotonin indices of immunocompetent cells in the intact and experimental animals.
