The effects of the prostaglandin (PG) precursor, arachidonic acid (AA), and the primary PG's, PGF2alpha, and PGD2, on lung function were compared in 39 intact-chest, paralyzed, artificially ventilated dogs. Intravenous AA decreased dynamic compliance (Cdyn) and functional residual capacity and increased airway resistance (Rl) and transpulmonary pressure at end-passive expiration. The decrease in Cdyn correlated closely with a rise in pulmonary arterial pressure (Ppa). Indomethacin abolished airway and vascular responses to AA, but did not attenuate responses to the PG's. The effects of AA, PGD2, and PGF2alpha on lung function and Ppa were similar, whereas PGE2 had little effect. Vagotomy attentuated the RL increase in response to AA, PGE2alpha, and PGD2 and the Cdyn decrease in response to the PG's. The effects of the PG's on compliance were greater than those produced by mechanically increasing pulmonary venous pressure. The present studies suggest that the PG precursor is rapidly converted to agents that have marked effect on both pulmonary vessels and airways, particularly peripheral airways, in the dog.
