Journal ArticleDOI
Platelet activating factor (PAF) involvement in endotoxin-induced hypotension in rats. Studies with PAF-receptor antagonist kadsurenone.
TL;DR: Evidence from three types of experiments indicates that platelet activating factor (PAF)1 is an important mediator of endotoxin-induced hypotension in rats, and these endot toxin-refractory rats do respond to subsequent PAF infusions.
Journal ArticleDOI
Characterization of a platelet-activating factor receptor antagonist isolated from haifenteng (Piper futokadsura): specific inhibition of in vitro and in vivo platelet-activating factor-induced effects.
T. Y. Shen,San-Bao Hwang,Michael N. Chang,Thomas W. Doebber,My-Hanth T. Lam,Margaret Wu,Xui Wang,Gui Qiu Han,Run Zhi Li +8 more
TL;DR: A novel antagonist of PAF is identified in the methylene chloride extract of a Chinese herbal plant, haifenteng, which inhibits PAF-induced increases of hematocrit and circulating N-acetylglucosaminidase in the rat at greater than 10 mg/kg i.p. in a dose-dependent manner.
Journal ArticleDOI
Specific binding sites for platelet activating factor in human lung tissues.
TL;DR: The data indicate that human lung tissues contain PAF specific receptors, and binding of PAF to these receptor sites may be the first step to initiate PAF-induced lung pathophysiology.
Journal Article
Characterization of cutaneous vascular permeability induced by platelet-activating factor in guinea pigs and rats and its inhibition by a platelet-activating factor receptor antagonist.
TL;DR: Kadsurenone, a competitive specific receptor antagonist, inhibits both histamine- and bradykinin-induced rat cutaneous vascular permeability which suggests that PAF may be involved in the vasopermeability induced by histamine and bradaykinin.
Journal ArticleDOI
Novel analgesic-antiinflammatory salicylates.
J. Hannah,William V Ruyle,Howard Jones,A. R. Matzuk,K. W. Kelly,B. E. Witzel,W. J. Holtz,R. A. Houser,T. Y. Shen +8 more
TL;DR: 5-(2,4-Difluorophenyl)salicylic acid, diflunisal, is the best compound, in terms of both efficacy and safety, from over 500 salicylates investigated in the authors' laboratories.
