[Detection of new metabolic paramagnetic centers in the lung tissue by ESR method]. / Obnaruzhenie metodom EPR novykh metabolicheskikh paramagnitnykh tsentrov v tkaniakh legkogo.

ABSTRACT

An ESR signal with g = 2.0025 and delta H = 0.2 mT was recorded at 77 K in lung tissues of guinea-pigs, mouse and rats. The signal intensity changed in the lung tissues of animals exposed to some chemicals. A relationship between new paramagnetic centres and the lung surfactant system is suggested to exist.
