The energy-stabilizing and immunotropic action of immunomodulants trekrezan (25 mg/kg) and polyoxidon (0.75 mg/kg) was compared in rats with a model bronchopulmonary inflammation induced by the introduction of turpentine into trachea. Both drugs exhibited an energy-stabilizing effect, which was manifested by a decrease in the levels of lactate and the ATP-ADP and AMP hydrolysis products and by an increase in the level of pyruvate and ATP in blood lymphocytes and lung tissues. The energy-stabilizing action of polyoxidon was more pronounced in the lung tissue. The action of this drug was generally the same, but less pronounced than the effect of trekrezan. The parallel experiments showed that trekrezan and polyoxidon normalized the immune status of lymphocytes in rats with the model acute bronchopulmonary inflammation.
