[Prevention of acute pulmonary edema in irradiated organisms]

Experiments were conducted on 212 albino rats. Preparations giving a marked prophylactic effect in the progress of the lung edema in the nonirradiated animals failed to influence the course of edema and even aggravated it in some of irradiated (650 R) animals. On the contrary, preparations ineffective or negatively influencing the nonirradiated animals were capable of causing a marked prophylactic effect in the irradiated animals. Consequently, the antiedema preventive measures in the irradiated and nonirradiated organisms should be different.
