  • Current scintigraphic tests of gastrointestinal motor function provides relevant pathophysiologic information, but their clinical utility is controversial. Many scintigraphic methods are developed to investigate gastrointestinal motility from oral cavity to colon. These are esophageal transit scintigraphy, oropharyngeal transit study, gastric emptying test, small bowel transit time measurement, colon transit study and gastroesopahgeal reflux scintigraphy. Scintigraphy of gastrointestinal tract is the most physiologic and noninvasive method to evaluate gastrointestinal motility disorders. Stomach emptying test is regarded as a gold standard in motility study. Gastrointestinal transit scintigraphy also has a certain role in assessment of drug effect to GI motility and changes alter therapy of motility disorders. Scintigraphy provides noninvasive and quantitative assessment of physiological transit throughout the gastrointestinal tract, and it is extremely useful for diagnosing gastrointestinal motor dysfunction. This article reviews the current procedures, indications, significance and guidelines for gastrointestinal motility measurements by scintigraphy.

  • Objectives: This study aimed to evaluate the efficacy of Daegunjoong-tang for improvement of gastrointestinal motility after surgery due to gastrointestinal cancer by analyzing the existing clinical research. Methods: Clinical studies about Daegunjoong-tang for improvement of gastrointestinal motility after surgery due to gastrointestinal cancer were identified in a literature search using the search term "Daikenchuto AND cancer AND ileus." The studies were analyzed in terms of design, inclusion and exclusion of participants, intervention, control, outcomes, and results. Results: Nine articles were identified in the literature search. Four trials included colon cancer participants with colectomy, and three studies included gastric cancer with total gastrectomy. The intervention in each case was Daegunjoong-tang, and most interventions were made by a pharmaceutical company with a Good Manufacturing Practice facility. The most frequently used control was a placebo. The methods were diverse, including measuring gastrointestinal function, motility, quality of life, symptom scores with a numeric rating scale, and blood tests. Safety was investigated by recording adverse events. Conclusions: Some issues were discovered by reviewing the existing clinical research about Daegunjoong-tang for improvement of gastrointestinal motility after surgery for gastrointestinal cancer. These results will be utilized as evidence for using Daegunjoong-tang in clinical practice and designing a clinical trial for Korean patients.

  • The knowledge of motility disorders of the gastrointestinal tract has increased over the past decades. The development of newer therapies for bowel motility disorders has been disappointingly slow. Prokinetic agents are medications that enhance coordinated gastrointestinal motility and transit of material in the gastrointestinal tract. These agents are pharmacologically and chemically diverse. However, life-threatening adverse effects of prokinetic agents such as cisapride was present. In this review, pharmacologic effects and use of prokinetic agents in children was introduced.

  • The pharmacological rationale of Agastache rugosa (AR) or Pogostemon cablin (PC), which have been used in traditional Korean medicine to treat dampness pattern or syndrome in gastrointestinal tract, was investigated on the gastrointestinal disorders. In-vivo model studies that examined the effect on the gastrointestinal disorders of AR or PC were collected. They were classified into disease-induced in-vivo models or non-disease in vivo models. The target disease, animal species, induction method, administration, and outcomes (changes in morphological and histological parameter, or blood and fluid) of each study were analyzed. The therapeutic mechanism of AR or PC extract was evaluated by the induced diseases and the changes in outcomes. There were contradictory reports on gastrointestinal motility of AR or PC in disease non-disease in-vivo model. AR or PC inhibited gastrointestinal motility in disease model of increased gastrointestinal motility, while promoted motility in disease model of decreased gastrointestinal motility. AR or PC also inhibited inflammatory changes in gastrointestinal inflammation model. These results suggest that the bidirectional regulation of gastrointestinal motility and the improvement of gastrointestinal inflammatory disorders might underpin traditional therapeutic effect of AR or PC, that is effect to resolve dampness of gastrointestinal tract.

  • Manometry is a noninvasive diagnostic tool for identifying motility dysfunction of the gastrointestinal tract. Despite the great technical advances in monitoring motility, performance of the study in pediatric patients has several limitations that should be considered during the procedure and interpretation of the test results. This article reviews the clinical applications of conventional esophageal and anorectal manometries in children by describing a technique for performing the test. This review will develop the uniformity required for the methods of performance, the parameters for measurement, and interpretation of test results that could be applied in pediatric clinical practice.

  • The present study was undertaken to determine whether combined treatment with prokinetic trimebutine and mosapride has a synergic effect on gastrointestinal motility and visceral pain associated with gastrointestinal dysfunction. To develop effective gastroprokinetic agents with greater potencies than trimebutine or mosapride for the treatment of gastrointestinal tract disease, a mixture of trimebutine and mosapride was designed and prepared. In the present study, treatment with trimebutine alone showed a dose-dependent effect on propelling movements of normal small and large intestine in mice, whereas mosapride effected only small intestine motility. Co-administration of trimebutine with mosapride, a well-established prokinetic drug, produced a synergistic influence on normal small intestine motility, but demonstrated an unclear effect on large intestine motility, with a slight tendency to reduce the propelling time. In a stress model, the small and large intestine motilities were significantly decreased. The reduction of intestine motility was restored to a normal level and the restoring effect was more pronounced in the combined treatment with trimebutine plus mosapride than treatment with trimebutine or mosapride alone. Furthermore, treatment with trimebutine plus mosapride significantly decreased acute visceral pain which was not controlled by trimebutine or mosapride alone. These data suggest that combination therapy with trimebutine plus mosapride has a synergic effect on small and large intestine motility and visceral pain control in gastrointestinal disorders.

  • 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: The purpose of this study was to investigate the effects of Shengmai-san and Pyungwi-san, a herbal product used in traditional Chinese medicine, on gastrointestinal (GI) motility in mice. Methods: The in vivo effects of Shengmai-san and Pyungwi-san on GI motility were investigated by measuring the intestinal transit rates (ITRs) using Evans blue in normal mice and in mice with experimentally induced GI motility dysfunction (GMD). GMD was induced by injecting acetic acid or streptozotocin intraperitoneally. Results: In normal Institute of Cancer Research mice, ITRs were significantly and dose-dependently increased by Shengmaisan (0.01~1 g/kg) and Pyungwi-san (0.01~1 g/kg). The ITRs of acetic acid induced peritoneal irritation model and streptozotocin-induced diabetic model mice were significantly reduced compared to normal mice, and these reductions were significantly and dose-dependently inhibited by Shengmai-san (0.01~1 g/kg) and Pyungwi-san (0.01~1 g/kg). Conclusions: These results suggest that both Shengmai-san and Pyungwi-san are a good candidate for the development of a prokinetic agent that may prevent or alleviate GMD.

  • Objectives: The purpose of this study was to investigate the effects of Socheongryong-tang, a traditional herbal medicine, on gastrointestinal (GI) motility disorders (inflammatory and diabetic models) in mice. Methods: The in vivo effects of Socheongryong-tang on GI motility were investigated by calculating percent intestinal transit rates (ITR) and gastric emptying (GE) values using Evans Blue and phenol red, respectively, in normal mice and in mice with experimentally induced GI motility dysfunction (GMD). GMD models were induced by acetic acid and streptozotocin. Results: In normal ICR mice, ITR and GE values were significantly and dose-dependently increased by the intragastric administration of Socheongryong-tang (0.0025~0.25 g/kg). The ITR values (%) of GMD mice were significantly lower than those of normal mice, and these reductions were significantly and dose-dependently inhibited by Socheongryong-tang. Conclusions: These results suggest that Socheongryong-tang is a good candidate for the development of a prokinetic agent that may prevent or alleviate GMD.

  • Gastrointestinal motility consists of phasic slow-wave contractions and the migrating motor complex (MMC). Eupatilin (Stillen$^{(R)}$) has been widely used to treat gastritis and peptic ulcers, and various cytokines and neuropeptides are thought to be involved, which can affect gastrointestinal motility. We performed a study to identify the effects of eupatilin on lower gastrointestinal motility with electromechanical recordings of smooth muscles in the human ileum and colon. Ileum and colon samples were obtained from patients undergoing bowel resection. The tissues were immediately stored in oxygenated Krebs-Ringer's bicarbonate solution, and conventional microelectrode recordings from muscle cells and tension recordings from muscle strips and ileal or colonic segments were performed. Eupatilin was perfused into the tissue chamber, and changes in membrane potentials and contractions were measured. Hyperpolarization of resting membrane potential (RMP) was observed after administration of eupatilin. The amplitude, AUC, and frequency of tension recordings from circular and longitudinal smooth muscle strips and bowel segments of the ileum and colon were significantly decreased after admission of eupatilin. Eupatilin elicited dose-dependent decreases during segmental tension recordings. In conclusion, eupatilin (Stillen$^{(R)}$) showed inhibitory effects on the human ileum and colon. We propose that this drug may be useful for treating diseases that increase bowel motility, but further studies are necessary.
