Histochemical examinations of localization and activity of DPNH- diaphorase, succinic acid dehydrogenase, ATPase, aikaiine and acid phosphatase, and nonspecific as well as E-600-resistant esterase were performed in the lungs of guinea pigs at various stages of acute radiation sickness and after local irradiation of the lungs. The radiation syndrome was caused by a single exposure of the whole animal body to an x-ray dose of 400 r. Pulmonary tissue was x irradiated with 400 r. Detection of enzymes was done 24 hr, 4 and 11 days after whole-body irradiation and 4 days after local irradiation. Results show a decrease of respiratory ferments in the lung after whole-body as well as local irradiation. This may be significant for the oxidationprocesses. ATP-ase and alkaline phosphatase decreased with the two types of irradiation and this may be related to disturbance s in the active substratum transport from blood to cytoplasm and the reverse. The reaction to acid phosphatase showed an increasing tendency, the cause of which was a quantitative increase of the phagocytal cells of the lung, which contain this enzyme in abundance. Thiolacetesterase decrease could be causally connected with disturbances oi the fat metabolism. A quantitative increase of E -600-resistant esterase is explained with intensified protcolytic processes. (auth)
