The effects of β2-agonists and methylxanthines on neutrophil function in vitro. C.G. Llewellyn-Jones, R.A. Stockley. ERS Journals Ltd 1994. ABSTRACT: Therapeutic agents which affect polymorphonuclear neutrophil (PMN) functions have the potential to reduce or increase PMN activation and, hence, influence the progression of lung inflammation. We have assessed the effects of the β2-agonist, terbu...

The study was aimed to compare the effects of pentoxyphylline, aminophylline, choline theophyllinate and ethymizol on guinea pig and dog trachea with those of theophylline, papaverine and ephedrine. The effects of these drugs on the basal tension, on dose-response curves for muscle contraction produced by histamine and on cAMP level were investigated in guinea pig trachea, together with their i...

In this study, we compared leaf morphology and the phenolic and methylxanthine contents of different teas (Camellia sinensis (L.) Kuntze). Different tea types in loose leaf form available in the Italian market were investigated. The presence of numerous fine silvery-white hairs on the young leaves and buds, and the small-clavate glands on the leaf margins, light-colored and gelatinous in young ...
