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.

Take the blood specimen to measure the hepatic and renal function and the tissue biopsy after the active and motive abnormities called toxical manifestation such as posture changes, abnormal sound, uneasiness, quiet, thrill, ataxia, convulsion and so on with toxic dose. Measure the tissue biopsy after death with lethiferous dose. If no toxicity or death occur after the experiment of 12 weeks, measure the hepatic and renal function and the tissue biopsy. There was no rat which had the toxical manifestation such as active or motive abnormities and 3 rats died because of environment or others after the experiment of 12 weeks.

实验中分别测定治疗剂量组小鼠在用药4周，8周，12周后的肝肾功能，并进行组织病理检查；中毒剂量组小鼠在出现行为、动作异常，如改变姿势、叫声异常、不安、安静、震颤、运动失调、惊厥等中毒表现时，取血液标本测定肝肾功能，并进行组织病理检查；致死剂量组小鼠发生死亡后进行组织病理检查；若12周实验结束时无小鼠出现中毒表现或死亡，则取血液标本测定肝肾功能，并进行组织病理检查。12周实验结束时，无小鼠出现动作、行为异常等中毒表现，有3只小鼠因为环境或其它原因发生死亡，病理检查结果正常。

The method has been applied to the determination of polysaccharide content in Ligusticum Chuanxiong Hort., and the result agrees with Dubois' method.
