.freelatic effects of longxiangpingchuan capsule(LXP).Methods Observation the effect of LXP on the latent period of inducing asthma induced by spraying acetylcholine-histamine in guinea pigs; Observation the antitussive effect of LXP by lung overfloaking isolated tracheal chain of guinea pigs;Observation the effect of LXP on immunological function by carbon particle clearance test in mice; Observation the effect of LXP on delayed anaphylaxis induced by ovum protein in rats;Observation the hypoxia tolerant and anti-tired effects of LXP by hypoxia tolerance test and the anti-tired test of LXP could significantly prolong the latent period of inducing asthma in guinea pigs induced by spraying acetylcholine-histamine,inhibit the increase of lung overfloine in anesthetized guinea pigs,relax the bronchus smooth muscle markedly,reduce the times of cough induced by ammonia protein in and lengthen the survival time of mice in anoxic LXP has the notable antitussive and antiasthmatic effects.
龙香平喘胶囊(longxiangpingchuan capsul)主要由穿山龙、云香草、地龙等几味中药组成,具有止咳、平喘、调节免疫、抗变态反应、抗疲劳、耐缺氧等功效,常用于治疗急、慢性支气管炎引起的咳嗽、喘息。将这些传统的止咳、平喘中草药制成胶囊,既便于患者服用,又有利于药物吸收,增强疗效。笔者力图通过一系列的药理实验,研究该药的止咳、平喘等药理作用。
