title: Effect of the beta-2 adrenergic agonist fenoterol on the release of leukotrienes and prostaglandin D2 from human lung parenchyma.
abstract: Ca++-ionophore and antigen challenge of human lung fragments caused a massive release of leukotrienes, whose relative proportions varied considerably and were dependent on the experimental conditions. A broncho-selective beta 2-adrenoceptor agonist fenoterol was able to prevent the antigen-induced leukotriene release completely, whereas the Ca++-ionophore induced leukotriene release was only moderately inhibited. The HPLC data were confirmed by SRS-A bioassay.
