[Bronchial mediators and receptors: current data].

This is a very precise study of the mechanisms which intervene in bronchial motility. It is apparent that the most important recent acquisitions in the realm of bronchial mediators, over these last 10 years remains: the demonstration in the animal and in man of the duality between adrenergic bronchoconstriction of alpha nature and adrenergic bronchoconstriction of beta-2 nature, the duality of the effects of prostaglandins (PGF2 alpha broncho-constrictive, and PGE2 bronchodilator), and the role of cyclic AMP at the junction of the action of numerous substances which are active on the bronchial musculature.
