Abstract: | Under conditions of local administration of uridine-H3 solution a study was made of the dynamics of the isotope incorporation into the RNA of the nuclei and the cytoplasm of the perikarion of the hyperchromic motor neurons of the ventro-lateral nucleus of mouse spinal cord. An increase in the content of hyperchromic neurocytes in the population under study was reached in mice as a result of swimming for four hours. A different character of the label regression curves for the hyperchromic and normochromic motor neurons was shown. |
