[Antioxidant system of the rat brain in toxic lung edema].

The state of enzymatic and nonenzymatic components of antioxidant system and also lipid peroxidation processes were studied in brain of rats with toxic pulmonary edema induced by inhalation of nitric oxides. The changes in the state of antioxidant system components in brain accompanied the development of toxic pulmonary edema. The main changes were found in nonenzymatic components of the antioxidant system, particularly in thiol and disulfide groups.

[Antihypoxic and antiedemic activity of new condensed indole derivatives].

The antihypoxic and antiedemic activity of a series of new indole derivatives and condensed systems, including pyrimido-, thiazolo-, and triazinoindoles, was studied on the hypobaric hypoxic hypoxia ad toxic lung edema models. Several thiazoloindole and formylindole derivatives prevented the loss of experimental animals under hypoxia conditions and significantly reduced the toxic lung edema development. The pharmacological activity of these compounds was comparable with or exceeded that of the standard antihypoxic and antiedemic drugs.

[Status of the blood and lung antioxidant system of the rat in toxic pulmonary edema].

The state of enzymatic and non-enzymatic components of antioxidant system and also lipid peroxidation processes in blood and lungs of rats with toxic pulmonary edema induced by inhalation of nitric oxides were investigated. The changes in the state of blood and lung antioxidant system components accompany the development of toxic pulmonary edema and coincide in time-course of edema manifestation. The determined changes were more pronounced in blood than in lungs.
