This study was undertaken to investigate the effects of Yijintang and Gami-Yijintang on the gastrointestinal functions of the rats. Sprague-Dawley rats were used for experimental animals, each animal was administrated Yijintang(Sample Ⅰ group, 47.5 mg/ml) and Gami-Yijintang(Sample Ⅱ group, 38.37 mg/ml, Sample Ⅲ group, 85.3 mg/ml) water extract once a day. The changes of the gastric juice volume and the intestinal mobility index were measured. And It was observed the effects on colitis induced by dextran sulfate sodium in the rats.
The following results were obtained ;
1. The gastric juice volume was decreased significantly in the sample Ⅰ group (P<0.05) compared to the control group. But there was not siginificant effect in the sample Ⅱ and sample Ⅲ groups.
2. The moving distance of carbon bolus was increased siginificantly in the sample Ⅱ (P<0.05) and sample Ⅲ (P<0.05) groups compared to the control group. But there was not siginificant effect in the sample Ⅰ group.
3. The intestinal mobility index was increased significantly only in the sample Ⅲ group (P<0.05) compared to the control group.
4. The feces consistency was increased significantly on the 3rd and 5th day of the sample Ⅰ group (P<0.05), on 3rd, 4th, and 5th day of the sample Ⅱ (P<0.05) and the sample Ⅲ (P<0.05) groups compared to the control group.
5. The feces property index was increased significantly only on the 5th day of the sample Ⅲ group (P<0.05) compared to the control group.
6. The number of WBC and RBC, levels of hemoglobin and hematocrit were not changed in all sample groups compared to the control group.
7. The number of the type B Goblet cells were increased significantly in the sample Ⅱ (P<0.05) and the sample Ⅲ (P<0.05) groups, the number of the type C Goblet cells were decreased significantly only in the sample Ⅲ group (P<0.05) compared to the control group.
