[Effects of a membrane modulator derived from 3-hydroxypyridine class on the development of pulmonary edema].

The experiment on white rats has revealed that water-soluble antioxidant-emoxipin, having obvious membrane modulating effect, does not influence the rate of watering and congestion of the lungs, the speed of reabsorption of fluid from lung tissue, the permeability of the capillary-alveolar barrier both in the blood-tissue direction and vice versa. Preliminary introduction of emoxipin increased the amount of edema fluid in the lungs when noradrenaline, centrogenic and especially vasopressin pulmonary edema developed, but in did not influence the development of vagotomic pulmonary edema. Stimulation of adenylcyclase or introduction of prostacyclin slowed down the development of centrogenic and vasopressin edema of the lungs. On the basis of these data it can be concluded that the intensification of pulmonary edema after emoxipin introduction is connected with its antioxidant activity.
