哮喘病人化学介质的释放例如:组织胺,过敏性慢反应物质和前列腺素促使支气管平滑肌的收缩和腺体的分泌。此过程为钙离子从细胞外进入肥大细胞和嗜碱细胞的细胞体内的结果。心痛定抑制钙依赖的作用和最近发现心痛定能治疗运动诱发的哮喘(EIA)。关于EIA的预防问题作者研究了心痛定的这一方面的作用,和色甘酸钠作比较,心痛定同样有对肥大细胞的稳定作用和预防EIA。
The release of chemical mediators from asthmatic patients such as histamine, allergenic slow-acting substances, and prostaglandins promote bronchial smooth muscle contraction and glandular secretion. This process is the result of calcium ions entering the cells of mast cells and basophils from the outside of the cell. Cardiac pain inhibits the effects of calcium dependence and recently found that nifedipine is able to treat exercise-induced asthma (EIA). On the prevention of EIA The author studied the role of nifedipine in this respect, compared with cromolyn, nifedipine also have the same effect on the stability of mast cells and the prevention of EIA.
