title: [Identification of electron spin resonance signals of ribonucleotide reductase in animal tissues with high proliferative activity].
abstract: A new ESR signal (doublet with hyperfine splitting of 20 gauss and g = 2.005) was found for animal tissues having high level of proliferative activity. This signal is shown to be due to radical enzyme ribonucleotide reductase. The results reported for spleen development suggest that there is a correlation between changes in the enzyme activity during the first week of neonatal development and intensity of ESR doublet signal.
