[Electron paramagnetic resonance spectra with g=2.03 of the animal liver tissue treated with butylhydroxytoluene and diethylnitrosamine].

: ESR spectra g=2.03 intensities of rat liver tissues were studied under the action of cancer agent either diethylnitrosamine (DEN) with butylhydroxytoluene (BHT) injected before DEN or without BHT at 77 K. Combined influence of DEN and BHT upon the intensity change of ESR spectra with g=2.03 at animal disease is explained by modified action of DEN metabolism.
