The experiments on mice showed that subchronic food restriction to 40 and 8% of unrestricted ration is a strong stressor inducing devastation of lymphoid organs, primarily the thymus and spleen. The mice in the group with severe food restriction (8% of normal ration) demonstrated increased front paw grip force. We also observed an increase in spontaneous motor activity in these animals correlated with food restriction. Food deprivation led to inhibition of proliferative activity of the bone marrow cells and suppression of erythropoiesis. Moreover, severe food restriction was accompanied by a decrease in the number of double-strand DNA breaks evaluated by the release of γH2AX+-cells and the ratio of polychromatophilic erythrocytes.
