以钾离子透入引起大鼠甩尾的电流强度作为痛反应指标，尾核内微量注射L精氨酸、D精氨酸、硝普钠和血红蛋白等，观察0～30min内大鼠痛阈的变化。

Methods AH dry powder inhalation was prepared by spray-drying method. Following spray-drying, resultant powders were characterized using scanning electron microscopy and laser diffraction, and the aerosolisation performance was determined using twin-stage liquid impinger. The process conditions were optimized with orthogonal design combined with multi-index test. The powder yield, aerodynamic diameter, angle of repose and respirable fraction were used as indices for orthogonal design.
