Heaves是马和矮种马的呼吸系统疾病,其特征是急性气道阻塞和气道高反应性发作。我们测量了前列腺素E2(PGE 2)和15-羟基二十碳四烯酸(15-HETE)的生产在体外气管上皮细胞从6个受影响的马在急性气道阻塞的时间相比,6个匹配的对照马。制备上皮和上皮下组织条,并用A23187、组胺和缓激肽刺激。通过放射免疫测定法定量来自条的培养基中的PGE 2和15-HETE。15-仅在两只主要动物的上皮条中发现HETE高于准确检测限,而在对照马中均未发现HETE,并且刺激条时15-HETE的量未增加。从受影响的马的上皮条往往产生较少的PGE 2比从对照组的马,有一个显着的相关性上皮PGE 2的生产和受影响的动物所需的时间,以发展气道阻塞。上皮下组织条从控制马产生显着更多的PGE 2在响应A23187和缓激肽比受影响的马条。我们的结论是,马气管上皮是不是一个显着的来源15-HETE。气喘马的气道粘膜PGE 2产生减少,这表明这种支气管舒张物质的相对减少可能是这种哮喘模型发病机制的一个因素。
Heaves is a respiratory disorder of horses and ponies characterized by bouts of acute airway obstruction and airway hyperresponsiveness. We measured prostaglandin E2 (PGE2) and 15-hydroxyeicosatetraenoic acid (15-HETE) production in vitro in tracheal epithelium obtained from six affected horses at the time of acute airway obstruction as compared with six matched control horses. Strips of epithelium and subepithelial tissue were prepared and stimulated with A23187, histamine, and bradykinin. The PGE2 and 15-HETE in media from strips was quantitated by radioimmunoassay. 15-HETE above the limits of accurate detection was found in epithelial strips of only two principal animals and in none of the control horses, and the amount of 15-HETE was not increased when strips were stimulated. Epithelial strips from affected horses tended to produce less PGE2 than did strips from control horses, and there was a significant correlation between epithelial PGE2 production and the time taken for affected animals to develop airway obstruction. Subepithelial tissue strips from control horses produced significantly more PGE2 in response to A23187 and bradykinin than did strips from affected horses. We conclude that equine tracheal epithelium is not a significant source of 15-HETE. Airway mucosal PGE2 production is reduced in horses with heaves, which suggests that a relative decrease in this bronchorelaxant substance may be a factor in the pathogenesis of this model of asthma.
