[Role of ATP in the mechanism of serotonin absorption by lung tissue]

Tests set up on the isolated perfused lungs of albino rats and on intact dogs demonstrated that the serotonin absorption by the pulmonary tissue is attended by a drop of the ATP amount in the lungs. The exogenous ATP has no essential effect on the serotonin absorption by the pulmonary tissue, its considerable quantities being metabolized in the pulmonary capillaries.
