title: [Age related changes in rat blood leucocyte count and morpho-metrical parameters of large granular lymphocytes under different light regimens].
abstract: The effect of different light conditions on the age related level of blood leucocytes, leucocytes differential count and the morpho-metrical parameters of large granular lymphocytes in rats was investigated. It has been found that the senescent animals demonstrate disturbance in typical lymphocytes/ neutrophils ratio under condition with light and darkness changes natural and regular illumination. The total leucocytes number, the level of neutrophilic bands, eosynophils and large granular lymphocytes increased under continuous light illumination and natural photoperiod in Karelia. The comparatively lower level of lymphocytes and higher of neutrophils was formed earlier under light conditions without light and dark interchange, i.e. under long time light deprivation (DP) and under constant illumination (LL).
