近几年来,由于受体学说研究的不断进展,对α受体在哮喘发病中的作用有了进一步的认识。一系列实验和临床报告都指出;哮喘患者的β受体功能低下,而气管和支气管的α受体功能却亢进,使用α受体阻断剂或并用β受体兴奋剂治疗哮喘,可取得较好的疗效(一)气管和支气管的受体:现已证明,人的气管和支气管上不但 In recent years, due to the continuous progress of receptor theory, the role of α receptor in the pathogenesis of asthma has been further recognized. A series of experiments and clinical reports have pointed out that asthmatic patients with β receptor dysfunction, and trachea and bronchial α receptor function is hyperactive, the use of α-blockers or β-receptor agonists and asthma treatment can be obtained more Good effect (A) trachea and bronchial receptors: It has been shown that the human trachea and bronchus not only
