Objectives : This study was conducted to compare Chaenomelis Sinensis Fructus with Chaenomelis Lagenariae Fructus, and to examine Fructus chaenomelis having an influence on Intestinal Motility. Methods : We compared Chaenomelis Sinensis Fructus with Chaenomelis Lagenariae Fructus, by observing their effects on Intestinal Motility. Oral administration of water extracts of Chaenomelis Sinensis Fructus and Chaenomelis Lagenariae Fructus into albino rats was followed by dealing with carbachol or loperamide, injecting charcoal meal and measuring the moving length in the intestine. Results : By Chaenomelis Sinensis Fructus and Chaenomelis Lagenariae Fructus, the Intestinal Motility of normal albino rats did not change significantly. Chaenomelis Sinensis Fructus and Chaenomelis Lagenariae Fructus controled the accelerated Intestinal Motility of albino rats. Chaenomelis Sinensis Fructus was not different from the extracting method, Chaenomelis Lagenariae Fructus had effects of control on extracting by methanol significantly. When Chaenomelis Sinensis Fructus was compared with Chaenomelis Lagenariae Fructus, the former was proved to have control effects on Intestinal Motility in decoction extracts and extracts by ethyl ether higher than the latter. By both Chaenomelis Sinensis Fructus and Chaenomelis Lagenariae Fructus, the declined Intestinal Motility was not changed significantly. Conclusion : Chaenomelis Fructus suppressed the exasperated Intestinal Motility by carbachol, but did not influence the dropped Intestinal Motility by loperamide. In addition, Chaenomelis Sinensis Fructus was more excellent than Chaenomelis Lagenariae Fructus in its control effects of Intestinal Motility. inhibitory effects by DKT represent a potential therapeutic approach to the treatment of inflammatory diseases.
