[Effect of visible light on transformability of lymphocytes in peripheral blood].
Reported in this paper are the possible effects of different light regimes on the transformability of lymphocytes in calf blood. The following results were verified against the background of various indices, such as transformation rate, stimulation index, and lymphocyte number, following culturing with the lymphocyte transformation test and morphological evaluation: --The light regimes tested were natural light day, extremely long day with artificial light (24 hours of lighting, 75-100 lx), and divided artificial light day (seven hours light, five hours darkness, seven hours light, five hours darkness, 82-128 lx). The natural and extremely long artificial light days stimulated transformability of lymphocytes in calf blood. --The divided artificial light day tended to depress transformation of calf lymphocytes. Such light-dependent stimulation of lymphocyte transformability is interpreted as an improvement in defence of the animal organism in terms of an unspecific stimulation.
