C57B1/6 inbred mice were placed in hypomagnetic condition during 14 days constantly. Degree of relaxation of geomagnetic field was 10(4). The increase of the number of eosinophil granulocytes was discovered in peripheral blood of mice. Measures of circadian rhythms of blood's absolute lymphocytosis, absolute number of cells in bone marrow, thymus, spleen and inguinal lymph nodes were safe. Adaptation of lymphoid system to hypomagnetic condition was manifested by desynchronization of circadian rhythmicity on the basis of different sensitivity of lymphoid organs, that realized in strengthening of ultradian rhythms with periods of 15 hours. There are indirect data, that show the increase of speed and/or volume of recirculation of lymphoid cells.
