title: [The content of cyclic nucleotides, free cytoplasmic Ca2+ and malondialdehyde in the splenic lymphocytes and thymocytes of rats under the action of moderate doses of radiation].
abstract: It has been shown that the malonic dialdehyde (MDA) content in spleen lymphocytes of rats increases after whole-body X irradiation with a dose of 0.5 Gy to reach the maximum level in 24 h. Simultaneously, the concentration of cGMP and free cytosol Ca2+ increases. With a dose of 1 Gy MDA content of cells increases 6 h following irradiation. The maximum drop of the release of viable lymphocytes from the spleen and thymus, observed 24 h and 3 days after irradiation respectively, coincides with the appearance of the second peak of the MDA content. The level of cGMP remains decreased throughout the period of about 6 days. The onset of lymphocyte repopulation in the spleen on day 6 coincides with the decrease in the MDA level and increase in the cytosol Ca2+ concentration.
