Objective: The mechanism of dryness nature of Aurantii Fructus was clarified
and the effects of different processed products on c-kit and stem cell factor(SCF) mRNA expression of sinuses ventriculi and colon in normal rats were compared. Method: SD rats were divided into blank group
high(10 g·kg-1
similarly hereinafter) and low(1 g·kg-1
similarly hereinafter) dose group of crude Aurantii Fructus
high and low dose group of Aurantii Fructus processed with bran
high and low dose group of Aurantii Fructus processed with honey bran and slow transit constipation(STC) model group.Rats in each medication administration group were given corresponding solution with 1 time for a day
rats in model group were given compound diphenoxylate tablets solution and rats in the blank group were given the same volume of normal saline.All the experimental animal were administered continuously for 30 days.All rats were executed on the 30th day
and the sinuses ventriculi and colon tissues were immediately dissected.After that
the expression levels of c-kit and SCF mRNA in tissues were detected by real-time fluorescence quantitative polymerase chain reaction(PCR) amplifier. Result: Compared with the blank group
the c-kit and SCF mRNA expression of sinuses ventriculi and colon in crude Aurantii Fructus group were significantly decreased(P<0.01).Compared with the model group
there was no significant difference in all indexes of crude Aurantii Fructus group with high dose;and all the indexes of the other two groups were increased significantly(P<0.05
P<0.01). Conclusion: Keeping use high-dose of crude Aurantii Fructus in a long-term can significantly reduce the expression of c-kit and SCF mRNA in normal rat gastrointestinal tract
thus affecting the number and function of interstitial cells of Cajal in gastrointestinal tract
and resulting in intestinal dryness and constipation.Both of Aurantii Fructus processed with bran and honey bran can effectively alleviate the intestinal dryness effect caused by crude Aurantii Fructus
and Aurantii Fructus processed with honey bran has the better effect on reducing dryness than bran products.
