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.

This study was designed to confirm the effect of dietary protein level and oral administration of tryptophan on brain serotonin metabolism. Two animal experiments were conducted. The objectives and results of research were as follows : In the first experiment, it was investigated whether administration of reserpine to Sprague-Dawley rats fed 6% or 20% casein diet induced decrease in serum tryptophan and large neutral amino acid(LNAA) concentrations, tryptophan/LNAA concentration ratio, brain tryptophan, serotonin and 5-hydroxyindoleacetic acid(5-HIAA) contents. Brain serotonin content of 6% casein diet group was lower than those of 20% casein diet group. Both 6% and 20% casein diet groups administered with reserpine to induce the analogous depression, showed the notable decrease in brain serotonin content when they were compared with 20% casein diet group not administered with reserpine. Serum tryptophan/LNAA ration and brain 5-HIAA content showed a tendency similar to the change of serotonin content, but the mean difference among all groups was not significant. From these results, it could be said that when the dietary protein level was low, brain serotonin content was decrease. The second experimnt was to see the change in serum tryptophan concentration and tryptophan/LNAA ratio and brain tryptophan, serotonin and 5-HIAA content when tryptophan was administered orally to the animals treated with reserpine. Serum tryptophan concentration tended to increase in both reserpine-treated 6% and 20% casein diet groups administered with tryptophan, especially in the 6% casein diet group. Serum tryptophan/LNAA concentration ratio tended to incrase in reserpine-tteated 6% casein diet group, while decrease in reserpine-treated 20% casein diet group. Brain tryptophan content was increased in both reserpine-treated 6% and 20% casein diet groups. However, brain serotonin content of reserpine-treated 6% casein diet group showed a tendency to decrease, while that of reserpine-treated 20% casein group increase. Consequently, the effect of tryptophan administration on increase of brain tryptophan and serotonin content in animals treated with reserpine was far more excellent in 20% casein diet groups. It was concluded that dietary protein intake and tryptophan administration increase brain serotonin level. Accordingly, it was possible to confirm that brain function, particularly in aspect of behavior related to the serotonin, was changed with manipulation of dietary composition.

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.

We compared impulsive behaviors in Wistar rats and in Wistar-Kyoto rats. There was no significant difference in locomotor activity between them. However, Wistar rats showed high activity in 5-choice serial reaction time track. When Wistar rats were treated with atomoxetin (3 mg/kg), methylphenidate (2 mg/kg) or amphetamine (2 mg/kg), they showed less impulsive behavior. Serotonin contents in prefrontal cortex and brain stem also increased. In conclusion, we suggest that Wistar rats could be used as animal model for impulsive behavior analysis. In addition, serotonin might be related with this impulsivity.
