[Post-radiation changes in cyclic nucleotide levels and cAMP and cGMP in chromatin from rat blood lymphocytes].

The change of contents of cyclic nucleotides (cAMP and cGMP) in lymphocyte chromatin of rats blood under norm and after X-ray irradiating in doses 0.5; 1 and 7.76 Gy was established.

[Features of DNA synthesis in chromatin from rat blood lymphocytes upon exposure to varying doses of ionizing radiation].

Changes in the level of chromatin DNA synthesis after the total X-ray irradiation of rats in the dozes 0.5 Gr, 1 Gr and 7.76 Gr were shown.

[Regulatory components of the eukaryotic translation apparatus in normal states and after exposure to ionizing radiation].

The comparative analysis of content prostaglandins E2, F2 alpha and cAMP, cGMP in the compositions of the high-molecular aminoacyl-tRNA synthetase complexes and endoplasmic reticulum vesicules from the rat liver has been carried out. The influence of lethal and sublethal X-ray doses on the levels of cyclic nucleotides and prostaglandins has been studied. Cyclic nucleotides and prostaglandins proved to be rapid and high sensitive transmitters of ionizing radiation influence on the eukaryotic translation apparatus.
