Abstract
  1. Application of capsaicin solution onto the rat pharyngeal mucosa caused a well-reproducible increase in vascular permeability in the pharynx. 2. Capsaicin-induced pharyngeal inflammation was unaffected by a histamine H1 blocker and non-steroidal anti-inflammatory agents, whereas dexamethasone was effective in its inhibition. 3. FK224, a dual antagonist of tachykinin NK1 and NK2 receptors, and FK888, a selective antagonist of NK1 receptor, significantly inhibited capsaicin-induced plasma exudation in the pharynx. 4. In capsaicinized animals, the application of capsaicin solution in the pharyngeal mucosa did not induce pharyngitis. 5. These results suggest that the mechanism of the capsaicin-induced pharyngitis primarily involves tachykinins.
摘要
  1. 将辣椒素溶液应用于大鼠咽黏膜可导致咽部血管通透性出现可重复的增加。2. 组胺H1受体阻滞剂和非甾体抗炎药对辣椒素诱导的咽炎没有影响,而地塞米松可有效抑制该炎症。3. 速激肽NK1和NK2受体的双重拮抗剂FK224以及NK1受体的选择性拮抗剂FK888可显著抑制辣椒素诱导的咽部血浆渗出。4. 在经辣椒素处理的动物中,在咽黏膜应用辣椒素溶液不会诱发咽炎。5. 这些结果表明,辣椒素诱导咽炎的机制主要涉及速激肽。
