Leukotriene inhibitors preferentially inhibit hypoxic pulmonary vasoconstriction in isolated rat lungs. If lipoxygenase products are involved in the hypoxic pressor response they might be produced during acute alveolar hypoxia and a leukotriene inhibitor should block both the vasoconstriction and leukotriene production that occurs in response to hypoxia. We investigated in isolated blood perfused rat lungs whether leukotriene C4 (LTC4) could be recovered from whole lung lavage fluid during ongoing hypoxic vasoconstriction. Lung lavage from individual rats had slow reacting substance (SRS)-like myotropic activity by guinea pig ileum bioassay. Pooled lavage (10 lungs) as analyzed by reverse phase high performance liquid chromatography had an ultraviolet absorbing component at the retention time for LTC4. At radioimmunoassay, and SRS myotropic activity by bioassay. LTC4 was not found during normoxic ventilation, during normoxic ventilation after a hypoxic pressor response, or during vasoconstriction elicited by KCl. Diethylcarbamazine citrate, a leukotriene synthesis blocker, concomitantly inhibited the hypoxic vasoconstriction and LTC4 production. Thus 5-lipoxygenase products may play a role in the sequence of events leading to hypoxic pulmonary vasoconstriction.
