Abstract: ObjectiveObserving the distribution and the change of the quantity of SP,VIP in the colon tissue of 'cathartic colon'rats.MethodsWe divided the 32 wistar rats weighted (200 ±10)g into 2 groops randomly:the blank group( n =8) and model group( n =8).we induced the 'cathartic colon'rats with the suspension of dahuang.The blank group were given the distilled water for contrast.After one week during the time Dahuang was stopped.We killed them,measured the carbon powder propulsion rates in the intestine and then took Specimen after the 8 rats were fasted 24 hours as well as the blank group,but water were given.We compared the variation of SP,VIP distribution between two groups.ResultsThe carbon powder propulsion rates in the model group were slower than that in the saline control group.The distribution of SP,VIP are all more than that in the blank group.ConclusionThe distribution of SP,VIP are all more than that in the blank group.
