Methods The experimental arrhythmia models were induced with barium chloride (BaCl2),uabaina and aconitine in rats and cobayaes.The incidence rate and mortality rate of arrhythmia,the emergence time and the duration of arrhythmia induced with BaCl2 were recorded in rats pretreated with CASI (in dosages of 25,50, and 100 mg·kg-1 sublingual vein injection).At the same time,the dosages of uabaina and aconitine were observed when the ventricular premature contraction,ventricular tachycardia,ventricular fibrillation and cardiac asystole were appeard in rats and cobayaes pretreated with CASI (in dosages of 25,50, and 100 mg·kg-1 sublingual vein injection).

制备氯化钡(BaCl2)、哇巴因及乌头碱诱导的大鼠及豚鼠实验性心律失常模型，CASI按25、50、100 mg·kg-1分为3个剂量组，舌下静脉给药1次，不给CASI作为对照组，记录大鼠给BaCl2后心律失常的发生率、出现时间、持续时间及动物的死亡率；观察豚鼠及大鼠出现室性早搏、室性心动过速、心室颤动及心脏停搏时哇巴因及乌头碱的用量。

Further study found that Cyperus could antagonist the excitation effect of Ach and BaCl2 on the intestinal smooth muscle.

Results ①Five days after abdominal application of Xiaoji power(0.1 g per mouce),the medicine showed a very significant effect in enhancing gastrointestinal propulsive function.② Xiaoji powder not only had relaxing effect on the normal smooth muscle in vitro,but also had a strong spasmolytic effect on acetylcholine,green bariuminduced spasm of intestinal smooth muscle.The experiment was based on 10 μg atropine sulfate as a positive control to carry out control experiments.It showed the graphics of atropine sulfate in spasmolytic role.③Xiaoji powder navel paste therapy played a positive role in adjusting the gastrointestinal electric disorder caused by deficiency of spleen Qi,and could restore it to its normal state.

结果 （1）以0.1 g/只消积散给予小鼠腹部用药5 d，即显示非常显著的增强胃肠推进功能作用；（2）消积散不仅对正常离体平滑肌有舒张作用，同时对由于乙酰胆碱、氯化钡引起的肠平滑肌痉挛也有强的解痉作用，该实验是以硫酸阿托品10 μg作为阳性对照药进行对照实验，显示了硫酸阿托品的解痉作用图形；（3）消积散敷脐对脾虚引起的胃肠电紊乱有明显的调节作用，使脾虚大鼠的胃肠电基本恢复到正常状态。
