Bronchoconstriction induced by intratracheal administration of platelet-activating factor (PAF-acether) in baboons
Intratracheal administration of PAF-acether (60 μg.kg−1) was performed in six premedicated, curarized and mechanically ventilated baboons. Whereas intratracheal administration of an equal amount of solvent (200μl...
