RESUMEN
During and after exposure to a constant magnetic field of 1.6 T mice, showed variations in the size distribution of red blood cells, with their shape remaining unchanged and enlarged cells being predominant. This shift persisted till exposure day 10 and began to return to normal on days 15, 22 and 30. After irradiation the Price-Jones curve varied in a different manner and recovered by day 6. The changes in the curve were not correlated with variations in the reticulocyte and erythrocyte counts or hemoglobin content. It is concluded that an exposure to a constant magnetic field produces insignificant lesions in the red blood cell membrane. Mention should be made of a reduction of the reticulocyte count in the peripheral blood after exposure.

Animal adaptation to a strong magnetic field was investigated. Mice were exposed to 30-day total-body continuous effects of a constant magnetic field (CMF) of 1.6T, and their physiological responses were assessed. Analysis of the data obtained showed that different parameters varied in a dissimilar manner. Red blood changes returned to normal in the course of the experiment. Leucocytosis and increased content of catecholamines and corticosterone of blood and adrenals persisted throughout the exposure. Changes in the spermatogenic epithelium were most distinct after the exposure. The recovery of certain parameters during the CMF exposure is indicative of adaptation of some physiological systems. The adaptation is, however, incomplete as suggested by the long persisting stress manifestation. Reticulocytopenia and spermatogenetic abnormalities found after exposure are of particular importance.
