Objective:To study the effect of Shutong Capsule on defecating function with type of dry stagnation in stomach and intestines.Method: Through feeding with rice and prohibition of drinking water three days

we prepared the rat model and mouse model with coprostasis type of dry stagnation in stomach and intestines.And then

using Shutong Capsule（high

medium and low dosage

ig） as the treatment

first time of defecation and grains of defecation in 4 h for normal mice and dry stool constipation mice

and periotalsis of intestine for normal rats and dry stool constipation rats were all observed and recorded.Result:There were no impact on purgation for normal mice and rat.There were significant differences between all the drug groups and model group in first time of defecation and grains of defecation in 4 h of mice（P < 0.01 or P < 0.05）.The effect of Shutong high

medium dosage group was more evident than that in the low one（P < 0.001）.Shutong high

medium dosage group were significantly increased comparing with model group in the pushing length and percentage of rat intestine（P < 0.001 or P < 0.01）.Conclusion:Shutong Capsule can moisten intestines and urge purgation

increase the peristalic rate of intestine for type of dry stagnation in stomach and intestines.
