Delayed gastrointestinal (GI) motility is frequent adverse effect associated with chemotherapy, and induced by serotonin releases from enterochromaffin cells. Ijintang-gamibang (IJG) is a digestive polyherbal formula has been traditionally used in Korea and consisted of 8 types of medicinal herbs. This study was conducted to determine whether or not IJG aqueous extracts can prevent delayed GI motility induced by the antineoplastic drug cisplatin chronically administered, once per week for five consecutive weeks (2 mg/kg). 200, 100 and 50 mg/kg of IJG extracts were orally administered, once a day for 14 days from fourth cisplatin treatment, and the changes in body weight gain, fecal parameters, gastrointestinal transit ratio and histopathology were observed. In addition, pylorus gastrin and serotonin contents were also measured with immunohistochemical observations of enterochromaffin cells contains gastrin and serotonin, as compared with ondansetron, a serotonin 5-HT3 receptor antagonist, 1 mg/kg. Cisplatin treatment related body weight decreases, delayed GI motility, decreases of fecal water contents were significantly and dose-dependently inhibited by oral treatment of IJG extracts, and they also inhibited the pylorus gastrin and serotonin changes induced by cisplatin treatment. The overall effects of IJG 100 mg/kg were similar to that of ondansetron 1 mg/kg. The present results supported that IJG aqueous extracts have favorable ameliorating effect on the delayed GI motility induced by chemotheraphy, modulated the GI enterochromaffin cells, serotonin and gastrin-producing cells with antioxidant effects. This effect of IJG may help improve accompanying gastrointestinal symptoms by chemotherapy.

Objectives This study aimed to observe the effect of Taeumjowi-tang on the cisplatin-induced gastrointestinal dysfunctions in rats. Methods Four groups, each of 8 rats per group, were used in this study. Saline and distilled water treated control rats were intact vehicle control group. Delayed gastrointestinal motility was induced by intraperitoneal treatment of cisplatin 2mg/kg, once a week for 5 weeks(Cisplatin control group). Taeumjowi-tang aqueous extracts(TJ) were orally administered in a volume of 5ml/kg, once a day for 14 days from 4th cisplatin treatment(TJ group). Ondansetron 1mg/kg was subcutaneously treated, in a volume of 1ml/kg, as same as TJ(ondansetron group). We measured the body weights, intestinal charcoal transit ratio, fecal parameters, fundus MDA(malondialdehyde), GSH(glutathione) contents and SOD(superoxide dismutase), CAT(catalase) activities, TPH(tryptophanhydroxylase) and MAO(monoamine oxidase) activities, pyloric gastrin and serotonin contents with their immunoreactive cells, colonic serotonin-immunoreactive cells, the histopathology of pylorus, fundus mucosa and colon. Results 1) The body weight gains, the small intestinal charcoal transfer rates, the fecal parameters(numbers, weights and water contents) were increased in TJ, ondansetron group. 2) The inhibit of fundus antioxidant defense systems by cisplatin were decreased in TJ, ondansetron group. 3) The pyloric TPH activities were increased and the pyloric MAO activities were decreased in TJ group. 4) The pyloric gastric contents and the gastrin-immunoreactive cells were increased and the pyloric serotonin contents and the pyloric and colonic serotonin-immunoreactive cells were decreased in TJ group. 5) The pylorus atrophic changes and the gastric surface erosive damage regions by cisplatin were favorably inhibited by treatment of TJ group. Conclusions The results obtained in this study suggest that TJ favorably retarded the cisplatin related GI(gastrointestinal) dysfunctions and constipation through modulations of GI enterochromaffin cells, serotonin and gastrin-producing cells and antioxidative systems.

The aim of this study was to evaluate the effects of soyoligosaccharides on intestinal microflora transit time lipid profiles and immune responses. Forty-eight male rats of Sprague-Dawley strain were divided into six groups(SYS: soybean oil-sucrose SYO: soybean oil-oligo SES; esame oil-sucrose SEO:sesame oil-oligo BFS : beef tallow-sucrose BFO : beef tallow-oligo) soyoligo-groups(SYO, SEO, BEO) were fed the diet containing 5% soyoligosaccharides but control groups not fed them and all groups were fed 20% fats for 4 weeks. The number of fecal bifidobacteria tended to increase after soyoligosaccharides feeding. The significant increase was found in SEO group compared to SES in that of fecal bifidobacteria,. Stool wet weight dry fecal weight and stool water content were increased significantly in soyoligo-group(SYO, SEO, BFO) compared to control groups(SYS, SES, BFS) and gastrointestinal transit time(TT) tended to increase. Soyoligosaccharides lowered plasma cholesterol in SEO group significantly more than did other groups. soyoligo-groups(SYO, SEO, BFO) tended to decrease liver triglycerides compared to control groups. Plasma IgG concentration increased in beef tallow groups(BFS, BFO) than that in other dietary fat groups. Soyoligosaccharides and kinds of fats had effects on plasma C3 concentration and mitogenesis of the spleen cells. Soyoligosaccharides had no effects on plasma leptin and insulin concentration but kinds of fats did so that sesame groups were decreased significantly in plasma leptin concentration but increased significantly in plasma insulin concentration compared to other dietary fat groups. In conclusion dietary soyoligosaccharides changed the composition of the intestinal microflora beneficially with sesame oil and partially had effect on plasma and liver lipid profiles .(Korean J Nutrition 33(6) : 597∼612, 2000)

This study examined the laxative effects of mulberry leaf extract (MLE) fermented by lactic acid bacteria (LAB), which contains high levels of polyphenolic and flavonoid compounds, against loperamide-induced constipation in rats. Sprague-Dawley rats were divided into a normal group (N) and three experimental groups; loperamide treated group (C), loperamide and LAB-fermented MLE 300 mg/kg treated group (MLEL), and loperamide and LAB-fermented MLE 600 mg/kg treated group (MLEH). After 33 d, fecal pellet amount, fecal weight, water content of fecal, gastrointestinal transit time and length, and serum lipid profiles were measured. Constipation was induced via subcutaneous injection of loperamide (2.0 mg/kg b. w., twice a day) for the final 5 d of the experiment. After loperamide administration, the LAB-fermented MLE groups showed a significantly increase in the fecal pellets number, wet weight, and water content in rats compared with the C group. Moreover, increases in the intestinal length and viable Lactobacillus numbers in the feces were observed in the LAB-fermented MLE groups. The intestinal transit time was shorter in the LAB-fermented MLE groups than in the C group. In addition, the LAB-fermented MLE groups showed a significant decrease in triglyceride and total cholesterol levels and an increase in HDL-cholesterol level. These results indicated that oral administration of LAB-fermented MLE shows laxative effect in loperamide-induced constipated rats.

The purpose of this study was to investigate the effects of dietary xylooligosaccharide on lipid levels of serum in rats fed high cholesterol diet. Male Sprage-Dawley rats weiging 100$\pm$10g were randomly assigned to groups of two normal(N, N+10X) and four high cholesterol diets which contained 1%(w/w) cholesterol. High cholesterol diet groups were classified to xylooligosaccharide free diet (C group), 5% xylooligosaccharide diet(C+5X group), 10% xylooligosaccharide diet(C+10X group) and 15% xylooligosaccharide diet(C+15X group) according to the level of dietary xylooligosaccharide supplementation. These experimental diets were fed ad libidum for 4 weeks. The weight gain of high cholesterol diet group were significantly increased more than that of normal group, but those of 10% and 15% dietary xylooligosaccharide groups were significantly decreased more than that of high cholesterol diet(C)group. The higher content of xylooligosaccharide, the more food intake was increased. The food efficiencies of 10%, 15% cholesterol diet groups were lower than that of high cholesterol diet(C)group. The levels of serum triglyceride(TG) and total cholestoral were significantly high in cholesterol diet groups compared with normal diet group but were decreased in groups fed 5% and 10% dietary xylooligosaccharide. Especially, the lowest level showed in group fed high cholesterol diet containing 10% xylooligosacchride. High cholesterol diet group containing 10% xylooligosaccharide increased HDL-cholesterol level and then decreased LDL-cholesterol level and atherogenic index compared with other groups. The level of TBARS(thiobarbituric acid reactive substances) in serum was decreased in rat group fed xylooligosaccharide in high cholesterol diet. The higher content of xylooligosacchride, the more gastrointestinal transit time was decreased. The results indicate that dietary xylooligosaccharide can improve status of TG and total cholesterol and repress lipid peroxidation in serum lipid at hypercholesterolemia induced by high cholesterol diet.

This experiment was carried out to investigate the effects of dietary mulberry leaf power on gastrointestinal function of rats. Plot containing one and ten percent mulberry leaf powder was supplied with rats. The food efficiency ratio (FER) of rat fed with 10% mulberry leaf powder was decreased 14%. the transit time of rat fed with 1% and 10% mulberry leaf was faster 16% and 21% than that of control respectively. Intestine length was increased 10% and 11% at 1% and 10% dietary mulberry leaf respectively. The transit speed was faster 30% at 1% dieatry mulberry leaf than that of control. The pH of rat's feces supplied with mulberry leaf was lower than that of control. The amount of daily rat's feces fed mulberry leaf was much than that of control. As above results, we suggest that mulberry leaf was evaluated to improve the function of rat's gastrointestine.

2 week study was conducted to investigate the effects of Interferential Current(IC) and Kaltenborn-Evjenth Orthopedic Manual Therapy(KEOMT) on functional constipation. Interventions were applied to spinal segments between $T_9-L_2$ which provides innervations to the gastrointestinal tract. Subjects(n=24) were randomly allocated to two treatment groups: the IC group or the KEOMT group. Results for the IC therapy demonstrated significant decrease with the colonic transit time(CTT) as well as scores on the constipation assessment scale(CAS). The frequency of defecations per week had increased significantly(p<0.05). The KEOMT displayed decreased CTT in the left colon region. The scores on the CAS were reduced and frequency of defecations per week had increased significantly (p<0.05). This study not only showed that both modes of therapy improved symptoms of constipation, but also optimized gastrointesti. nal content movement, eventuating in a more normalized CTT. In conclusion, both the IC therapy and the Kaltenborn-Evjenth Orthopedic Manual Therapy have shown to be effective interventions for improving functional constipation.

Upper gastrointestinal contrast studies were performed to compare the quality of images using two different commercialized barium products in 10 healthy beagle dogs of each group; 30% barium suspension in group 1, and 35% dilute barium suspension in group 2. Contrast media were administered through gastric tube at a dose rate of 10 ml/kg in all groups. All procedures were evaluated by three criteria: the quality of the images obtained, the transit time and the distensibility of the bowel. The imaging in group 1 showed good image quality, a rapid transit time, and good distensibility of bowel loop.

This study was conducted to evaluate the potential of the transformed Lactobacillus reuteri Pg4 (T-Pg4) harboring the ${\beta}$-glucanase gene as a poultry probiotic. The probiotic properties of the T-Pg4 strain were evaluated in vitro by their adherence capability and acid and bile salt tolerance, and were evaluated in vivo by their survival and adhesion in the gastrointestinal tract (GIT) of specific-pathogen-free (SPF) chickens. The results showed that the T-Pg4 strain exhibited resistance to acidic conditions and contact with bile salt, and adhered efficiently to the crop and intestinal epithelial cells of chickens in vitro. The T-Pg4 strain also could survive and colonize the gastrointestinal epithelium of the experimental SPF chickens in vivo. In addition, radial enzyme diffusion was used to demonstrate that the Lactobacillus spp. randomly isolated from the GIT of the SPF chickens fed T-Pg4 possessed ${\beta}$-glucanase secretion capability. These findings have demonstrated that the transformed L. reuteri Pg4 survives transit through the stomach and intestine, and may secrete ${\beta}$-glucanase in the chicken GIT. Therefore, it is suggested that this organism could be used as a multifunctional poultry probiotic.

Although major advances have been achieved in our understanding and treatment of diseases in many areas of medicine, relatively few improvements have been made in the area of gastrointestinal (GI) motor function. The dried root of Codonopsis pilosula (Franch.) Nannf. (CP) has been used as a traditional folk medicine for improving poor GI function in East Asia, including China and Korea. In the present study, neither aqueous (CP-W) nor ethanolic (CP-E) extracts of CP showed significant toxicity, even at an oral dose of 5 g/kg to mice. The effects of CP-W and CP-E on GI motor function were investigated by measuring in vivo the gastric emptying rate (GER) and intestinal transit rate (ITR) in mice. In normal mice, the ITR was significantly increased by CP-W in a dose-dependent manner, whereas the GER was not significantly affected by any CP extracts. The ITR was significantly retarded in the mice with experimental GI motility dysfunction (i.e., peritoneal irritation by acetic acid) compared with that in normal mice. However, the retardation was significantly recovered by the pre-treatment of CP-W in a dose-dependent manner. The above results suggest that CP-W might be a potential prokinetic agent preventing or alleviating GI motility dysfunctions in human patients.
