Abstract
Postoperative ileus (POI) often decreases patients' QOL because of prolonged hospitalization and readmission. Alvimopan, a peripheral μ-opioid receptor antagonist, is currently the only therapeutic drug for POI. The aim of this study was to examine the efficacy of naldemedine (a peripheral μ-opioid receptor antagonist with a non-competitive pharmacological profile different from that of alvimopan) on postoperative intestinal hypomotility and adhesion in rodent models, and compare it with the effects of alvimopan. Oral administration of naldemedine (0.3 mg/kg) and alvimopan (3 mg/kg) significantly inhibited the decrease in intestinal motility induced by mechanical irritation in mice (p < 0.01, for both). Naldemedine (1 mg/kg) significantly shortened the adhesion length in chemical-induced postoperative adhesion model rats (p < 0.05). Alvimopan (3 mg/kg) also significantly reduced the adhesion ratio (p < 0.01). These findings suggest that naldemedine is effective for postoperative intestinal hypomotility and adhesions in rodents (i.e., as for alvimopan). Thus, naldemedine may be a useful option for the treatment of POI.

Abstract
Under physiological or pathological conditions, transient receptor potential (TRP) channel vanilloid type 1 (TRPV1) and TRP ankyrin 1 (TRPA1) possess the ability to detect a vast array of stimuli and execute diverse functions. Interestingly, increasing works have reported that activation of TRPV1 and TRPA1 could also be beneficial for ameliorating postoperative ileus (POI). Increasing research has revealed that the gastrointestinal (GI) tract is rich in TRPV1/TRPA1, which can be stimulated by capsaicin, allicin and other compounds. This activation stimulates a variety of neurotransmitters, leading to increased intestinal motility and providing protective effects against GI injury. POI is the most common emergent complication following abdominal and pelvic surgery, and is characterized by postoperative bowel dysfunction, pain, and inflammatory responses. It is noteworthy that natural herbs are gradually gaining recognition as a potential therapeutic option for POI due to the lack of effective pharmacological interventions. Therefore, the focus of this paper is on the TRPV1/TRPA1 channel, and an analysis and summary of the processes and mechanism by which natural herbs activate TRPV1/TRPA1 to enhance GI motility and relieve pain are provided, which will lay the foundation for the development of natural herb treatments for this disease.

Abstract
Background and Aim A number of basic and clinical studies have confirmed that the traditional Japanese herbal medicine, Daikenchutou (DKT) has a pharmacological effect on cholinergic and serotonergic mechanisms with a favorable safety profile and an improving effect on lower gastrointestinal (GI) symptoms including abdominal pain or bloating. The purpose of this study is to evaluate the efficacy and safety of DKT on chronic constipation. Methods This multicenter, randomized, placebo-controlled, double-blinded clinical trial enrolled 67 patients with chronic constipation fulfilling Rome III criteria. After a 2-week observation period, 63 patients with persistent symptoms were finally randomized to a 4-week course of treatment with DKT or placebo. The primary endpoint consisted of a global assessment of overall treatment effect (OTE), while the secondary endpoints consisted of improvements in stool consistency, spontaneous bowel movements, lower GI symptoms related to constipation, and quality of life. Factors associated with OTE were also investigated. Results After 4 weeks administration of DKT, OTE was significantly higher than placebo. No side effects were observed. Significant improvement in stool consistency and lower GI symptoms was observed in the DKT group. The improvements in lower GI symptoms as well as stool consistency were associated with OTE. OTE was higher in patients with greater improvement in lower GI symptoms with mental component summary scores close to normal before treatment. Conclusion DKT was effective and safe in treating chronic constipation, especially in patients having symptoms related to constipation with no impaired mental component summary score.

Abstract
PURPOSE This randomized crossover trial investigated the effects of Daikenchuto (DKT: TJ-100) on gastrointestinal symptoms of patients after colon and rectosigmoid cancer surgery. METHODS Among patients who had completed surgery for colon cancer, including rectosigmoid cancer, over 6 months ago, 20 who complained of gastrointestinal symptoms were enrolled. Subjects were randomly assigned to two sequences: sequences: A and B. In period 1, sequence A subjects were orally administered DKT, whereas sequence B subjects were untreated for 28 days. After a 5-day interval, in period 2, sequences A and B were reversed. Quality-of-life markers (GSRS and VAS), the Sitzmark transit study, the orocecal transit time (lactulose hydrogen breath test) and Gas volume score were evaluated before and after each period with findings compared between the presence of absence of DKT administration. RESULTS Between sequences, there were no significant differences in clinicopathological characters or any evaluations before randomization. There was no carryover effect in this crossover trial. The administration of DKT significantly ameliorated the GSRS in total, indigestion, and diarrhea, although the planned number of subjects for inclusion in this trial was not reached. CONCLUSIONS DKT may ameliorate subjective symptoms for postoperative patients who complain of gastrointestinal symptoms.

Abstract
We conducted a prospective randomized study to investigate the effect of daikenchuto (DKT) on abdominal symptoms following laparoscopic colectomy in patients with left-sided colon cancer. Patients who suffered from abdominal pain or distention on postoperative day 1 were randomized to either the DKT group or non-DKT group. The primary endpoints were the evaluation of abdominal pain, abdominal distention, and quality of life. The metabolome and gut microbiome analyses were conducted as secondary endpoints. A total of 17 patients were enrolled: 8 patients in the DKT group and 9 patients in the non-DKT group. There were no significant differences in the primary endpoints and postoperative adverse events between the two groups. The metabolome and gut microbiome analyses showed that the levels of plasma lipid mediators associated with the arachidonic acid cascade were lower in the DKT group than in the non-DKT group, and that the relative abundance of genera Serratia and Bilophila were lower in the DKT group than in the non-DKT group. DKT administration did not improve the abdominal symptoms following laparoscopic colectomy. The effects of DKT on metabolites and gut microbiome have to be further investigated.

Abstract
Respiratory-gated four-dimensional phase-contrast vastly undersampled isotropic projection reconstruction (4D PC-VIPR) is magnetic resonance (MR) imaging technique that enables analysis of vascular morphology and hemodynamics in a single examination using cardiac phase resolved 3D phase-contrast magnetic resonance imaging. The present study aimed to assess the usefulness of 4D PC-VIPR for the superior mesenteric artery (SMA) flowmetry before and after flow increase was induced by the herbal medicine Daikenchuto (TJ-100) by comparing it with Doppler ultrasound (DUS) as a current standard. Twenty healthy volunteers were enrolled in this prospective single-arm study. The peak cross-sectionally averaged velocity was measured by 4D PC-VIPR, peak velocity was measured by DUS, and flow volume (FV) of SMA and aorta were measured by 4D PC-VIPR and DUS 25 min before and after the peroral administration of TJ-100. The peak cross-sectionally averaged velocity, peak velocity, and FV of SMA measured by 4D PC-VIPR and DUS significantly increased after administration of TJ-100 (4D PC-VIPR: the peak cross-sectionally averaged velocity; p = 0.004, FV; p = 0.035, DUS: the peak velocity; p = 0.003, FV; p = 0.010). Furthermore, 4D PC-VIPR can analyze multiple blood vessels simultaneously. The ratio of the SMA FV to the aorta, before and after oral administration on the 4D PC-VIPR test also increased (p = 0.015). The rate of change assessed by 4D PC-VIPR and DUS were significantly correlated (the peak cross-sectionally averaged velocity and peak velocity: r = 0.650; p = 0.005, FV: r = 0.659; p = 0.004). Retrospective 4D PC-VIPR was a useful modality for morphological and hemodynamic analysis of SMA.

Abstract
Objectives: This study aimed to elucidate the effect of the extract of daikenchuto (DKT), a Japanese Kampo medicine, on the contractile activity of the internal anal sphincter in conscious dogs. Methods: Force transducers were attached to the serosal surface of the rectum and the internal anal sphincter of male beagle dogs. In addition, the contractile activity of the rectum and the internal anal sphincter was continuously measured until 6 h after DKT administration via telemetry in the conscious state. The DKT dose was 1.5 g/body, and the administration route was intrarectal in the expectation of a direct effect on the rectoanal region. DKT was re-administered to the same animal after drug withdrawal, and the plasma concentrations of hydroxy-α-sanshool (HAS) and hydroxy-β-sanshool (HBS) before and after administration were measured. Results: After DKT administration, the contractile activity of the internal anal sphincter immediately increased, peaked at 10 min, continued for ≥1 h, and had almost disappeared after 4 h. Rectal contraction differed from that of the internal anal sphincter, with no significant contraction observed. HAS and HBS were found in the plasma of animals administered with DKT and persisted up to 2 h after the administration. Conclusions: This is the first report on in vivo telemetry demonstrating that DKT exhibited contractile effects on the dog's internal anal sphincter. The increased anal pressure and improvement of fecal incontinence symptoms observed in previous clinical studies may have been based on this sphincter contraction.

Abstract
PURPOSE To investigate the efficacy and safety of Daikenchuto (DKT) for colorectal cancer patients undergoing surgery with the potential risk of postoperative ileus (POI). METHODS Colorectal cancer patients with abdominal pain and distention, scheduled for surgery, were randomly assigned to a DKT group or a control group. Patients assigned to the DKT group were given 15 g of DKT per day during the perioperative period. We then compared the perioperative gastrointestinal symptoms between the two groups. RESULTS The aim for a sample size of 30 patients per group was not reached in time, so we conducted an analysis on 16 patients in each group. The visual Analogue Scale scores for abdominal pain and distention were similar in the two groups. The number of bowel movements per day on postoperative days (PODs) 1, 2, and 6 were significantly lower in the DKT group. The incidence of a sensation of incomplete bowel evacuation on PODs 3 and 28 was also significantly lower in the DKT group. There were no adverse events thought to be related to DKT. CONCLUSIONS DKT could potentially inhibit diarrhea and reduce the number of bowel movements per day and the sensation of incomplete bowel evacuation after colorectal surgery. Thus, the perioperative use of DKT may be safe for colorectal cancer patients with abdominal pain and distention, who undergo surgery.

Abstract
Daikenchuto (DKT), a Japanese Kampo medicine, had been reported to increase small intestinal blood flow after liver resection. The aim of this study was to evaluate the effects of early enteral feeding of DKT on portal venous flow and early bowel movement after living donor liver transplantation (LDLT) in an attempt to clarify whether these effects on bowel motility can prevent bacterial and/or fungal translocation. MATERIALS AND METHODS Our prospective study included the consecutive 16 LDLT recipients at Mie University Hospital between June 2006 and September 2009. Sixteen patients were divided into the 2 groups according to enteral feeding starting postoperative day (POD) 1: 8 patients in DKT (15 g/d) administration (DKT group, for 1 week) and 8 patients in tepid water administration (non-DKT group, for 1 week). Portal venous flow, portal venous pressure, presence of fungal infection (serum level of β-D-glucan and fungal polymerase chain reaction assay), time to first food intake, and time to first defecation were serially examined. RESULTS Portal venous flow (mean [SD] velocity) was significantly increased in DKT group compared with non-DKT group: 47.5 (12.9) vs 31.8 (15.4) (P = .04) on POD 1, 46.8 (11.5) vs 28.8 (12.5) (P = .03) on POD 3, and 42.3 (17.2) vs 25.2 (9.0) (P = .05) on POD 5. However, mean (SD) portal venous pressures did not significantly change between the 2 groups. Between the 2 groups (DKT vs non-DKT), the day of first oral intake was not significantly different: 6.9 (2.5) vs 11.3 (8.7) (P = .061), but the mean (SD) day of first defecation was significantly shorter in the DKT group: 3.9 (1.1) vs 5.5 (2.6) (P = .02). Although fungal polymerase chain reaction assay was not significantly different between the 2 groups (4 vs 4 positive cases), the mean (SD) serum levels of β-D-glucan were significantly lower in the DKT group than in the non-DKT group: 9.0 (7.4) vs 18.4 (15.9) pg/mL (P = .04). CONCLUSION Early enteral feeding of DKT after LDLT increased portal vein blood flow without increasing portal vein pressure and stimulated early bowel movement, which in turn might prevent fungal translocation.

Possible anti-inflammatory role of Zingiberis processum rhizoma, one component of the Kampo formula daikenchuto, against neutrophil infiltration through muscarinic acetylcholine receptor activation. J Pharmacol Sci 2018; 137:379-386. [PMID: 30145033 DOI: 10.1016/j.jphs.2018.08.001] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Revised: 07/23/2018] [Accepted: 07/26/2018] [Indexed: 12/17/2022] Open
Abstract
Zingiberis processum rhizoma (ZPR) is a major active component of daikenchuto (DKT), which induces anti-inflammatory action by inhibiting macrophage infiltration. However, it is unclear whether ZPR is related to DKT-induced anti-inflammatory action via a reduction of neutrophil infiltration against postoperative ileus (POI). In this study, we orally administered individual herbal components of DKT to mice four times before and after intestinal manipulation (IM). The anti-inflammatory action of each crude drug was evaluated by histochemical analysis of relevant molecules. The results showed that treatment with all herbal components of DKT significantly inhibits neutrophil infiltration. This inhibition of neutrophil infiltration by ZPR was significantly reduced in 5-hydroxytryptamine receptor 4 (5-HT4R) knockout (KO) mice but not in alpha-7 nicotinic acetylcholine receptor (α7nAChR) KO mice. Also, transient receptor potential ankyrin 1 (TRPA1) and muscarinic acetylcholine receptor (mAChR) antagonists partly and significantly inhibited the amelioration of neutrophil infiltration by ZPR. Therefore, DKT-induced anti-inflammatory action, mediated by inhibition of neutrophil infiltration in POI, depends, in part, on the effects of ZPR. ZPR activates TRPA1 channels, possibly in enterochromaffin (EC) cells, to release 5-HT. This 5-HT stimulates 5-HT4R in the myenteric plexus neurons to release acetylcholine, which, in turn, activates mAChR to inhibit inflammation in POI.

Abstract
Natural medicines (i.e., herbal medicines, traditional formulas) are useful for treatment of multifactorial and chronic diseases. Here, we present KampoDB (http://wakanmoview.inm.u-toyama.ac.jp/kampo/), a novel platform for the analysis of natural medicines, which provides various useful scientific resources on Japanese traditional formulas Kampo medicines, constituent herbal drugs, constituent compounds, and target proteins of these constituent compounds. Potential target proteins of these constituent compounds were predicted by docking simulations and machine learning methods based on large-scale omics data (e.g., genome, proteome, metabolome, interactome). The current version of KampoDB contains 42 Kampo medicines, 54 crude drugs, 1230 constituent compounds, 460 known target proteins, and 1369 potential target proteins, and has functional annotations for biological pathways and molecular functions. KampoDB is useful for mode-of-action analysis of natural medicines and prediction of new indications for a wide range of diseases.

Abstract
Purpose Intestinal dysfunction is one of the most common complications in patients after abdominal surgery. Daikenchuto (DKT), a traditional herbal medicine, is recently employed to improve postoperative intestinal dysfunction. The aim of this meta-analysis was to assess the efficacy of DKT in improving intestinal dysfunction after abdominal surgery. Methods PubMed, Embase, and the Cochrane library were systematically searched to identify randomized controlled trails (RCTs) in adult patients undergoing abdominal surgery, who were randomly distributed to administrate DKT and placebo. The primary outcomes included the time to first postoperative flatus or bowel movement. We used random-effects models to calculate summary mean differences (MDs) with 95% confidence intervals (CIs). Results Nine RCTs totaling 1,212 patients (618 in DKT, 594 in control group) were included in our study. Compared with control group, DKT can effectively improve postoperative intestinal dysfunction by shortening the time to first postoperative flatus (MD, −0.41; 95% confidence interval [CI], −0.66 to −0.16; P = 0.001) with significant heterogeneity (I2 = 71%, P = 0.004), and bowel movement (MD, −0.65; 95% CI, −0.97 to −0.32; P < 0.001) without significant heterogeneity (I2 = 40%, P = 0.14). Sensitivity analyses by indication of surgery and type of surgery yielded similar results. Conclusion These data provide limited evidence that DKT shows efficacy on improving intestinal dysfunction after abdominal surgery. However, the results should be interpreted cautiously, due to the heterogeneity of the studies included. Thus, the efficacy of DKT on improving postoperative intestinal dysfunction warrants further investigation.

Abstract
BACKGROUND Postoperative ileus is a major complication for persons undergoing abdominal surgery. Daikenchuto, a Japanese traditional medicine (Kampo), is a drug that may reduce postoperative ileus. OBJECTIVES To assess the efficacy and safety of Daikenchuto for reducing prolonged postoperative ileus in persons undergoing elective abdominal surgery. SEARCH METHODS We searched the following databases on 3 July 2017: CENTRAL, MEDLINE, Embase, ICHUSHI, WHO (World Health Organization) International Clinical Trials Registry Platform (ICTRP), EU Crinical Trials registry (EU-CTR), UMIN Clinical Trials Registry (UMIN-CTR), ClinicalTrials.gov, The Japan Society for Oriental Medicine (JSOM), American Society of Clinical Oncology (ASCO), Society of American Gastrointestinal and Endscopic Surgeons (SAGES). We set no limitations on language or date of publication. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing Daikenchuto with any control condition in adults, 18 years of age or older, undergoing elective abdominal surgery. DATA COLLECTION AND ANALYSIS We applied standard methodological procedures expected by Cochrane. Two review authors independently reviewed the articles identified by literature searches, extracted data, and assessed risk of bias of the included studies using the Cochrane software Review Manager 5. MAIN RESULTS We included seven RCTs with a total of 1202 participants. Overall, we judged the risk of bias as low in four studies and high in three studies. We are uncertain whether Daikenchuto reduced time to first flatus (mean difference (MD) -11.32 hours, 95% confidence interval (CI) -17.45 to -5.19; two RCTs, 83 participants; very low-quality evidence), or time to first bowel movement (MD -9.44 hours, 95% CI -22.22 to 3.35; four RCTs, 500 participants; very low-quality evidence) following surgery. There was little or no difference in time to resumption of regular solid food following surgery (MD 3.64 hours, 95% CI -24.45 to 31.74; two RCTs, 258 participants; low-quality evidence). There were no adverse events in either arm of the five RCTs that reported on drug-related adverse events (risk difference (RD) 0.00, 95% CI -0.02 to 0.02, 568 participants, low-quality evidence). We are uncertain of the effect of Daikenchuto on patient satisfaction (MD 0.09, 95% CI -0.19 to 0.37; one RCT, 81 participants; very low-quality of evidence). There was little or no difference in the incidence of any re-interventions for postoperative ileus before leaving hospital (risk ratio (RR) 0.99, 95% CI 0.06 to 15.62; one RCT, 207 participants; moderate-quality evidence), or length of hospital stay (MD -0.49 days, 95% CI -1.21 to 0.22; three RCTs, 292 participants; low-quality evidence). AUTHORS' CONCLUSIONS Evidence from current literature was unclear whether Daikenchuto reduced postoperative ileus in patients undergoing elective abdominal surgery, due to the small number of participants in the meta-analyses. Very low-quality evidence means we are uncertain whether Daikenchuto improved postoperative flatus or bowel movement. Further well-designed and adequately powered studies are needed to assess the efficacy of Daikenchuto.

Abstract
Daikenchuto (DKT), a traditional Japanese medicine, is widely used to treat various gastrointestinal disorders. This study aimed to investigate whether DKT could promote the anastomotic healing in a rat model. Pedicled colonic segments were made in left colon by ligation of the feeding arteries, and then intestinal continuity was restored. Colonic blood flow was analyzed by using ICG fluorescence imaging: Fmax, Tmax, T1/2, and Slope were calculated. Anastomotic leakage (AL) was found in 6 of 19 rats (31.6%) in the control group, whereas in 1 of 16 rats (6.2%) in the DKT group. The Fmax and Slope of DKT group were significantly higher than those of control group. DKT could promote the anastomotic healing, with the higher bursting pressure on postoperative day (POD) 2 and 5, the larger granulation thickness on POD 5, and neoangiogenesis on POD 5. Histological examination showed DKT exhibited a decreased inflammatory cell infiltration, enhanced fibroblast infiltration, and enhanced collagen density on POD 5. In the DKT group, the levels of TGFβ1 on POD 2 and VEGFα on POD5 were significantly higher, whereas the level of TNFα on POD 2 was significantly lower. Therefore, DKT could be effective for the prevention of AL following colorectal surgery.

Abstract
Dai-kenchu-to (TJ-100) is an herbal medicine used to shorten the duration of intestinal transit by accelerating intestinal movement. However, intestinal movement in itself has not been evaluated in healthy volunteers using radiography, fluoroscopy, and radioisotopes because of exposure to ionizing radiation. The purpose of this study was to evaluate the effect of TJ-100 on intestinal motility using cinematic magnetic resonance imaging (cine MRI) with a steady-state free precession sequence. Ten healthy male volunteers received 5 g of either TJ-100 or lactose without disclosure of the identity of the substance. Each volunteer underwent two MRI examinations after taking the substances (TJ-100 and lactose) on separate days. They drank 1200 mL of tap water and underwent cine MRI after 10 min. A steady-state free precession sequence was used for imaging, which was performed thrice at 0, 10, 20, 30, 40, and 50 min. The bowel contraction frequency and distention score were assessed. Wilcoxon signed-rank test was used, and differences were considered significant at a P-value <0.05. The bowel contraction frequency tended to be greater in the TJ-100 group and was significantly different in the ileum at 20 (TJ-100, 8.95 ± 2.88; lactose, 4.80 ± 2.92; P < 0.05) and 50 min (TJ-100, 9.45 ± 4.49; lactose, 4.45 ± 2.65; P < 0.05) between the groups. No significant differences were observed in the bowel distention scores. Cine MRI demonstrated that TJ-100 activated intestinal motility without dependence on ileum distention.

Abstract
BACKGROUND Postoperative paralytic ileus can be a difficult complication for both surgeons and patients. Causes and treatments have been discussed for more than two centuries, but have not yet been fully resolved. Daikenchuto (TJ-100, DKT) is a traditional Japanese herbal medicine. Recently, some beneficial mechanisms of DKT to relieve paralytic ileus have been reported. DKT can suppress inflammation, increase intestinal blood flow, and accelerate bowel movements. Therefore, we have designed a randomized controlled trial to investigate the effects of DKT on postoperative gastrointestinal symptoms following laparoscopic colectomy in patients with left-sided colon cancer at a single institution. METHODS/DESIGN As primary endpoints, the following outcomes will be evaluated: (i) grade of abdominal pain determined using the numeric rating scale (NRS), (ii) grade of abdominal distention determined using the NRS, and (iii) quality of life determined using the Gastrointestinal Quality Life Index (GIQLI). As secondary endpoints, the following will be evaluated: (i) postoperative nutritional status (Onodera's Prognostic Nutritional Index (PNI) and the Controlling Nutritional Status score (CONUT score)), (ii) duration to initial flatus, (iii) duration to initial defecation, (iv) bowel gas volume, (v) character of stool (Bristol Stool Form Scale), (vi) defecation frequency per day, (vii) postoperative complications (Clavien-Dindo classification), (viii) length of postoperative hospital stay, and (ix) metabolites in the stool and blood. This trial is an open-label study, and needs to include 40 patients (20 patients per group) and is expected to span 2 years. DISCUSSION To our knowledge, this is the first randomized controlled trial to investigate the effects of DKT on postoperative subjective outcomes (i.e., postoperative quality of life) following laparoscopic colectomy as primary endpoints. Exploratory metabolomics analysis of metabolites in stool and blood will be conducted in this trial, which previously has only been performed in a few human studies. The study aims to guide a future full-scale pragmatic randomized trial to assess the overall effectiveness of DKT to improve the postoperative quality of life following laparoscopic colectomy.

Abstract
PURPOSE Daikenchuto (DKT) has a stimulant effect on intestinal motility and reportedly has a positive effect on postoperative intestinal motility in patients with sigmoid colon cancer. In this study, we investigated the effects of DKT in patients with right-side colon cancer. METHODS This retrospective study included 88 patients with right-side colon cancer. We orally administered 7.5 g of DKT in the DKT group and did not administer any DKT to patients in the no-DKT group. All patients ingested radiopaque markers 2 h before surgery, which were used to assess intestinal motility. The postoperative intestinal motility was radiologically assessed by counting the numbers of residual markers in the large and small intestines. RESULTS The DKT and no-DKT groups showed no marked differences in the total number of residual markers or number of residual markers in the small intestine. However, in the elderly subgroup, the total number of residual markers in the DKT group was significantly less than in the no-DKT group. CONCLUSION Although DKT had some small effect on the postoperative intestinal motility for most patients, it may have positive effects in elderly patients.

Abstract
Background/Aims Dai-kenchu-to (DKT), a traditional Japanese herbal medicine, is known to increase gastrointestinal motility and improve ileal function. We tested our hypotheses that (1) pretreatment with DKT would block the colorectal distention-induced visceromotor response in rats, and (2) pretreatment with DKT would attenuate colorectal distention-induced adrenocorticotropic hormone (ACTH) release and anxiety-related behavior. Methods Rats were pretreated with vehicle or DKT (300 mg/kg/5 mL, per os). Visceromotor responses were analyzed using electromyography in response to colorectal distention (10, 20, 40, 60, and 80 mmHg for 20 seconds at 3-minutes intervals). Anxiety-related behavior was measured during exposure to an elevated-plus maze after colorectal distention. Plasma ACTH and serum corticosterone levels were measured after exposure to the elevated-plus maze. Results Colorectal distention produced robust contractions of the abdominal musculature, graded according to stimulus intensity, in vehicle-treated rats. At 40, 60, and 80 mmHg of colorectal distention, the visceromotor responses of DKT-treated rats was significantly lower than that of vehicle-treated rats. At 80 mmHg, the amplitude was suppressed to approximately one-third in DKT-treated rats, compared with that in vehicle-treated rats. Smooth muscle compliance and the velocity of accommodation to 60 mmHg of stretching did not significantly differ between the vehicle-treated and DKT-treated rats. Similarly, the DKT did not influence colorectal distention-induced ACTH release, corticosterone levels, or anxiety-related behavior in rats. Conclusions Our results suggest that DKT attenuates the colorectal distention-induced visceromotor responses, without increasing smooth muscle compliance, ACTH release or anxiety-related behavior in rats.

Abstract
Here we analyzed whether Daikenchuto (DKT) suppresses postoperative inflammatory reactions in patients who have undergone elective colorectal surgery. DKT is one of the most frequently prescribed traditional (Kampo) medicines in Japan. DKT is reported to have various beneficial effects on bowel disorders. It was recently reported that DKT also has an anti-inflammatory effect. Consecutive patients with colorectal cancer who underwent elective colorectal resection were separated into two groups. A total of 67 patients began a DKT regimen after surgery (DKT group) and 53 patients did not begin the DKT regimen after surgery (control group). We observed a steady postsurgery increase in the white blood cell (WBC) count of all patients on postoperative day 1 (POD 1), whereas the WBC count decreased at PODs 3 and 7. When we compared the WBC values of the DKT group (6147.2 ± 2217.3 per microliter) and control (7071.1 ± 2828.0 per microliter) groups on POD 7, we found significant differences (P = 0.038). There was no significant side effect due to DKT, except for one case of mildly impaired liver function. Our results suggest that DKT administration may have an anti-inflammatory effect during the postoperative period. Further studies are warranted to investigate the possibility of using DKT as a therapeutic agent based on its anti-inflammatory effect.

Abstract
Objective This exploratory trial was performed to determine whether Daikenchuto accelerates recovery of gastrointestinal function in patients undergoing open colectomy for colon cancer. Methods A total of 386 patients undergoing colectomy at 1 of the 51 clinical trial sites in Japan from January 2009 to June 2011 were registered for the study (JFMC39-0902). Patients received either placebo or Daikenchuto (15.0 g/day, t.i.d) between post-operative day 2 and post-operative day 8. Primary end-points included time to first bowel movement, frequency of bowel movement and stool form. The incidence of intestinal obstruction was evaluated post-operatively. The safety profile of Daikenchuto until post-operative day 8 was also evaluated. Results The results for 336 patients (Daikenchuto, n = 174; placebo, n = 162) were available for statistical analysis. The time to first bowel movement did not differ significantly between the two groups. All patients reported having diarrhea or soft stools immediately after surgery, and the time until stool normalization (50th percentile) in the Daikenchuto and placebo groups was 6 days and 7 days, respectively. The placebo group had a significantly greater number of hard stools at post-operative day 8 (P = 0.016), and bowel movement frequency continued to increase until post-operative day 8 as well. In contrast, bowel movement frequency in the Daikenchuto group increased until post-operative day 6, however decreased from post-operative day 7 and was significantly lower at post-operative day 8 compared with the placebo group (P = 0.024). Conclusion The moderate effects of Daikenchuto were observed ∼1 week after the operation. Although Daikenchuto had an effect on gastrointestinal function after open surgery in patients with colon cancer, this study did not show its clinical benefits adequately.

Abstract
Various colonic motor activities are thought to mediate propulsion and mixing/absorption of colonic content. The Japanese traditional medicine daikenchuto (TU-100), which is widely used for postoperative ileus in Japan, accelerates colonic emptying in healthy humans. Hydroxy-α sanshool (HAS), a readily absorbable active ingredient of TU-100 and a KCNK3/KCNK9/KCNK18 blocker as well as TRPV1/TRPA1 agonist, has been investigated for its effects on colonic motility. Motility was evaluated by intraluminal pressure and video imaging of rat proximal colons in an organ bath. Distribution of KCNKs was investigated by RT-PCR, in situ hybridization, and immunohistochemistry. Current and membrane potential were evaluated with use of recombinant KCNK3- or KCNK9-expressing Xenopus oocytes and Chinese hamster ovary cells. Defecation frequency in rats was measured. HAS dose dependently induced strong propulsive "squeezing" motility, presumably as long-distance contraction (LDC). TRPV1/TRPA1 agonists induced different motility patterns. The effect of HAS was unaltered by TRPV1/TRPA1 antagonists and desensitization. Lidocaine (a nonselective KCNK blocker) and hydroxy-β sanshool (a geometrical isomer of HAS and KCNK3 blocker) also induced colonic motility as a rhythmic propagating ripple (RPR) and a LDC-like motion, respectively. HAS-induced "LDC," but not lidocaine-induced "RPR," was abrogated by a neuroleptic agent tetrodotoxin. KCNK3 and KCNK9 were located mainly in longitudinal smooth muscle cells and in neural cells in the myenteric plexus, respectively. Administration of HAS or TU-100 increased defecation frequency in normal and laparotomy rats. HAS may evoke strong LDC possibly via blockage of the neural KCNK9 channel in the colonic myenteric plexus.

Abstract
PURPOSE This study aimed to assess the efficacy of daikenchuto (DKT), a commonly prescribed, traditional Japanese herbal medicine, on postoperative intestinal dysfunction after gastric cancer surgery. METHODS Patients with gastric cancer scheduled for a total gastrectomy were randomly assigned before surgery to receive either no treatment (n = 40; control group) or DKT (7.5 g/day, t.i.d.) for 3 months (n = 41) postoperatively. We examined gastrointestinal motility, stool attributes, the quantity of bowel gas, the quality of life, and the incidence of postoperative ileus. RESULTS During the hospital stay, significant differences were observed between the DKT group and controls in the number of stools per day (1.1 ± 0.6 vs 0.8 ± 0.4, respectively; P = 0.037) and stool consistencies (Bristol scale ratings were 3.7 ± 0.8 vs 3.1 ± 0.8, respectively; P = 0.041). The DKT group showed significant reductions in gas volume scores, calculated from abdominal radiographs, at 7 days, 1 month, and 3 months after surgery. The groups did not show significant differences in quality of life scores (based on the Gastrointestinal Symptom Rating Scale) or in the incidence of postoperative ileus. CONCLUSION DKT improved bowel movements, stool properties, and bowel gas. These results suggested that DKT promoted early postoperative bowel functions after total gastrectomy.

Abstract
BACKGROUND This multi-center, phase III trial assesses the efficacy of daikenchuto (TU-100) on gastrointestinal disorders after hepatic resection (UMIN Registration No. 000003103). MATERIALS AND METHODS A total of 231 patients, who underwent hepatic resection at 26 Japanese centers, were enrolled. Patients were randomly assigned to receive either oral doses (15 g/day, three times a day) of TU-100 or placebo control from preoperative day 3 to postoperative day 10, except on the day of surgery. Primary end points were the time from extubation until the first postoperative bowel movement (FBM-T), serum C-reactive protein (CRP) and ammonia levels. RESULTS Finally, 209 patients (TU-100: n = 108, placebo: n = 101) were included in the statistical analysis. The median FBM-T was 88.2 h (95 % CI 74.0-94.1) in the TU-100 group and 93.1 h (95 % CI 83.3-99.4) in the placebo group, demonstrating that TU-100 accelerated the time to first bowel movement significantly more than placebo control. Serum CRP levels did not differ significantly during the study period, although serum CRP levels in the TU-100 group tended to be lower than those in the placebo group in patients with grade B liver damage. Meanwhile, the two groups had similar serum ammonia levels. TU-100-related serious adverse events did not occur during the study. CONCLUSIONS TU-100 appears to improve gastrointestinal dysmotility and reduce serum CRP levels in patients with grade B liver damage after hepatectomy. TU-100 is an effective treatment option after hepatic resection in patients with liver cancer.

Abstract
BACKGROUND Daikenchuto (DKT), a gastrointestinal prokinetic Japanese herbal medicine, is prescribed for patients with postoperative ileus (POI) and adhesive bowel obstruction following abdominal surgery. Several mechanisms for the amelioration of POI by DKT have been suggested; however, it has remained unclear whether DKT shows anti-inflammatory effects in POI. In the present study, we investigated the effects of DKT in a mouse POI model and attempted to clarify the detailed mechanisms of action. METHOD Intestinal manipulation (IM) was applied to the distal ileum of mice. DKT was administered orally to the animals 4 times before and after IM. Gastrointestinal transit in vivo, leukocyte infiltration, cytokine mRNA expression and gastrointestinal motility were analyzed. We also investigated the effects of the α7nAChR antagonist methyllycaconitine citrate (MLA) on the DKT-mediated ameliorative action against POI, and we studied the effects of DKT on inflammatory activity in α7nAChR knockout mice. RESULTS DKT treatment led to recovery of the delayed intestinal transit induced by IM. DKT significantly inhibited the infiltration of neutrophils and CD68-positive macrophages, and inhibited mRNA expressions of TNF-α and MCP-1. MLA significantly reduced the anti-inflammatory action of DKT, and the amelioration of macrophage infiltration by DKT was partially suppressed in α7nAChR knockout mice. CONCLUSIONS In conclusion, in addition to the gastrointestinal prokinetic action, DKT serves as a novel therapeutic agent for POI characterized by its anti-inflammatory potency. The DKT-induced anti-inflammatory activity may be partly mediated by activation of α7nAChR.

Abstract
Treatment with kampo, the Japanese traditional medicine, is a form of pharmacological therapy that combines modern Western and traditional Asian medical practices. In Japan, various traditional medicines are often combined with Western medicines and prescribed for patients with diseases such as gastroesophageal reflux disease, functional dyspepsia, chronic gastritis, irritable bowel syndrome, and post-operative ileus. Based on numerous past observations, Japanese traditional medicines are thought to be particularly useful in the treatment of medically unexplained physical symptoms such as nausea, abdominal discomfort, and anorexia. However, the detailed mechanism by which they mediate their pharmacological action is yet unknown. In addition, the clinical evidence to support their use is insufficient. This review focuses on the basic evidence of the pharmacological action and the clinical efficacies of kampo medicines accumulated over several past decades. In addition, we introduce both the current novel insights into kampo medicines and the therapeutic approach employed when they are used to treat various disorders of the gastrointestinal tract.

Abstract
The functional roles of transient receptor potential (TRP) channels in the gastrointestinal tract have garnered considerable attention in recent years. We previously reported that daikenchuto (TU-100), a traditional Japanese herbal medicine, increased intestinal blood flow (IBF) via adrenomedullin (ADM) release from intestinal epithelial (IE) cells (Kono T et al. J Crohns Colitis 4: 161-170, 2010). TU-100 contains multiple TRP activators. In the present study, therefore, we examined the involvement of TRP channels in the ADM-mediated vasodilatatory effect of TU-100. Rats were treated intraduodenally with the TRP vanilloid type 1 (TRPV1) agonist capsaicin (CAP), the TRP ankyrin 1 (TRPA1) agonist allyl-isothiocyanate (AITC), or TU-100, and jejunum IBF was evaluated using laser-Doppler blood flowmetry. All three compounds resulted in vasodilatation, and the vasodilatory effect of TU-100 was abolished by a TRPA1 antagonist but not by a TRPV1 antagonist. Vasodilatation induced by AITC and TU-100 was abrogated by anti-ADM antibody treatment. RT-PCR and flow cytometry revealed that an IEC-6 cell line originated from the small intestine and purified IE cells expressed ADM and TRPA1 but not TRPV1. AITC increased ADM release in IEC cells remarkably, while CAP had no effect. TU-100 and its ingredient 6-shogaol (6SG) increased ADM release dose-dependently, and the effects were abrogated by a TRPA1 antagonist. 6SG showed similar TRPA1-dependent vasodilatation in vivo. These results indicate that TRPA1 in IE cells may play an important role in controlling bowel microcirculation via ADM release. Epithelial TRPA1 appears to be a promising target for the development of novel strategies for the treatment of various gastrointestinal disorders.

Abstract
Heat shock protein (HSP) 47 may play an important role in the pathogenesis of intestinal fibrosis. Daikenchuto (DKT), a traditional Japanese herbal (Kampo) medicine, has been reported to ameliorate intestinal inflammation. The aims of this study were to determine time-course profiles of several parameters of fibrosis in a rat model, to confirm the HSP47-expressing cells in the colon, and finally to evaluate DKT's effects on intestinal fibrosis. Colitis was induced in male Wistar rats weighing 200 g using an enema of trinitrobenzene sulfonic acid (TNBS). HSP47 localization was determined by immunohistochemistry. Colonic inflammation and fibrosis were assessed by macroscopic, histological, morphometric, and immunohistochemical analyses. Colonic mRNA expression of transforming growth factor β1 (TGF-β1), HSP47, and collagen type I were assessed by real time-polymerase chain reaction (PCR). DKT was administered orally once a day from 8 to 14 d after TNBS administration. The colon was removed on the 15th day. HSP47 immunoreactivity was coexpressed with α-smooth muscle actin-positive cells located in the subepithelial space. Intracolonic administration of TNBS resulted in grossly visible ulcers. Colonic inflammation persisted for 6 weeks, and fibrosis persisted for 4 weeks after cessation of TNBS treatment. The expression levels of mRNA and proteins for TGF-β1, HSP47, and collagen I were elevated in colonic mucosa treated with TNBS. These fibrosis markers indicated that DKT treatment significantly inhibited TNBS-induced fibrosis. These findings suggest that DKT reduces intestinal fibrosis associated with decreasing expression of HSP47 and collagen content in the intestine.

This study focused on the localization of transient receptor potential vanilloid type 1 (TRPV1) in the intestines in postoperative adhesion model rats and investigated the underlying mechanism for the anti-adhesion action of daikenchuto (DKT), especially in relation to TRPV1. Postoperative intestinal adhesion was induced by sprinkling talc in the small intestine. The expression of TRPV1 mRNA was examined by in situ hybridization and real-time RT-PCR. The effects of DKT and its major ingredient, hydroxy sanshool, with or without ruthenium red, a TRP-channel antagonist, on talc-induced intestinal adhesions were evaluated. The level of TRPV1 mRNA was higher in the adhesion regions of talc-treated rats than in normal small intestine of sham-operated rats. Localization of TRPV1 mRNA expression was identified in the submucosal plexus of both sham-operated and talc-treated rats; and in talc-treated rats, it was observed also in the myenteric plexus and regions of adhesion. Capsaicin, DKT, and hydroxy sanshool significantly prevented formation of intestinal adhesions. The effects of DKT and hydroxy sanshool were abrogated by subcutaneous injection of ruthenium red. These results suggest that pharmacological modulation of TRPV1 might be a possible therapeutic option in postoperative intestinal adhesion, which might be relevant to the prevention of postoperative adhesive obstruction by DKT.

The effect of traditional Japanese medicine (Kampo) on gastrointestinal function. Surg Today 2010; 40:1105-11.

Abstract
Traditional Japanese medicine (Kampo) is used to treat various disorders of the gastrointestinal tract in Japan, where it is fully integrated into the modern healthcare system. Recently, scientific research on herbal medicine in Japan has been reported in English journals. The objective of the current review is to introduce two traditional Japanese medicines and to provide evidenced-based information regarding their use. Daikenchuto, which consists of three different herbs, is the most frequently prescribed traditional Japanese medicine in Japan. Daikenchuto stimulates gastrointestinal motility though a neural reflex involving presynaptic cholinergic and 5-HT3 receptors. Daikenchuto improves postoperative bowel motility and postoperative ileus. Furthermore, it is reported to cause an increase in gastrointestinal hormones (motilin, vasoactive intestinal peptide, and calcitonin gene-related peptide) and intestinal blood flow. Rikkunshito, a traditional Japanese medicine consisting of eight herbs, is thought to stimulate gastrointestinal motility and ghrelin secretion. Rikkunshito is effective for improving the symptoms of functional dyspepsia, gastroesophageal reflux disease, and cisplatin-induced anorexia and vomiting. Traditional Japanese medicine has the potential to be used successfully in the treatment of gastrointestinal disorders. Details regarding the physiological and clinical effects of traditional Japanese medicine must be further examined in order to become more widely accepted in other countries.

Abstract
Daikenchuto (DKT), a pharmaceutical-grade traditional Japanese (Kampo) medicine, has been widely used for the treatment of various gastrointestinal disorders including postoperative ileus and has been integrated into the modern medical care system in Japan as a prescription drug. DKT is a multiherbal medicine consisting of Japanese pepper (zanthoxylum fruit), processed ginger, and ginseng with maltose as an additive. Despite substantial research on the pharmacological activities of DKT and its ingredients, the lack of studies on absorption, distribution, metabolism, and excretion of DKT has made it difficult to obtain a consistent picture of its mechanism of action. In the present study, we constructed an analysis procedure consisting of seven conditions of liquid chromatography and mass spectrometric analysis, which enabled the identification of 44 ingredients of DKT component herbs. We investigated the plasma and urine profiles of these ingredients 0.5 to 8 h after oral administration of 15.0 g of DKT in four healthy volunteers. The results indicated that 1) hydroxy-α-sanshool and [6]-shogaol, the prominent peaks in plasma derived from Japanese pepper and ginger, respectively, were detected at 0.5 h and thereafter decreased throughout the sampling period; 2) ginsenoside Rb(1), a prominent peak derived from ginseng, increased gradually during the sampling period; 3) glucuronide conjugates of hydroxy-sanshools, shogaols, and gingerols were detected in plasma and urine; and 4) no obvious differences between samples from the two male and the two female individuals were observed. These results provide a strong basis for future studies on pharmacokinetics and pharmacology of DKT.

Abstract
BACKGROUND AND AIMS Adrenomedullin (ADM) is a member of the calcitonin family of regulatory peptides, and is reported to have anti-inflammatory effects in animal models of Crohn's disease (CD). We investigated the therapeutic effects of daikenchuto (DKT), an extracted Japanese herbal medicine, on the regulation of endogenous ADM in the gastrointestinal tract in a CD mouse model. METHODS Colitis was induced in mice by intrarectal instillation of 2,4,6-trinitrobenzenesulfonic acid (TNBS); afterwards, DKT was given orally. Colonic damage was assessed on day 3 by macroscopic and microscopic observation, enzyme immunoassays of proinflammatory cytokines in the colonic mucosa, and serum amyloid A (SAA), a hepatic acute-phase protein. To determine the involvement of ADM, an ADM antagonist was instilled intrarectally before DKT administration. The effect of DKT on ADM production by intestinal epithelial cells was evaluated by enzyme immunoassay and real-time PCR. RESULTS DKT significantly attenuated mucosal damage and colonic inflammatory adhesions, and inhibited elevations of SAA in plasma and the proinflammatory cytokines TNFα and IFNγ in the colon. Small and large intestinal epithelial cells produced higher levels of ADM after DKT stimulation. A DKT-treated IEC-6 cell line also showed enhanced ADM production at protein and mRNA levels. Abolition of this effect by pretreatment with an ADM antagonist shows that DKT appears to exert its anti-colitis effect via up-regulation of endogenous ADM in the intestinal tract. CONCLUSION DKT exerts beneficial effects in a CD mouse model through endogenous release and production of ADM. Endogenous ADM may be a therapeutic target for CD.

Abstract
Management of functional gastrointestinal disorders is hindered by both poor efficacy and adverse effects of traditional pharmacological therapy. Herbal medicine may be an attractive alternative based on the perception of its 'natural' approach and low risk of side effects; however, the lack of standardization of drug components has limited the ability to perform rigorous clinical studies in Western countries. Japanese herbal medicine (JHM) is a standardized form of herbal medicine with regards to the quality and quantities of ingredients. While extensively studied and widely used in Asia, there is a paucity of data upon which physicians in other parts of the world may draw conclusions regarding the effectiveness of herbal medicine for gastrointestinal disorders. The aim of this study was to summarize the most recent developments in JHM for treatment of functional gastrointestinal disorders. Animal and human studies were systematically reviewed to identify published data of JHM used for treatment of gastrointestinal disorders. The herbal components of JHM were examined. Results describing the physiological and clinical effects of JHM were abstracted, with an emphasis on functional gastrointestinal disorders. JHM are associated with a variety of beneficial physiological on the gastrointestinal system. Patient-based clinical outcomes are improved in several conditions. Rikkunnshi-to reduces symptoms and reverses physiological abnormalities associated with functional dyspepsia, while dai-kenchu-to improves symptoms of postoperative ileus and constipation in children. This updated summary of JHM in the field of gastrointestinal disorders illustrates the potential for herbal medication to serve a valuable role in the management of patients with functional gastrointestinal disorders.

Abstract
Kampo medicine "Dai-kenchu-to" (DKT) has been used for treatment of ileus. The aim of this study was to evaluate the role of DKT on the bacterial translocation (BT) model in rats. Rats were divided into the following four groups: group 1, receiving only water, and groups 2, 3, and 4, receiving 100, 300, and 1,000 mg/kg/day of DKT. Rats were sacrificed 6 days after the beginning of the fast, and then the mesenteric lymph node was cultured. Inflammatory cytokines, intestinal integrity, and apoptosis were assessed. Incidence of BT in groups 3 (33%) and 4 (16%) was lower than in group 1 (66%). Interferon-gamma expression in groups 2, 3, and 4 was significantly lower than in group 1. Villous height and number of villus in groups 2, 3, and 4 were significantly taller and greater than in group 1. Apoptotic index in groups 2, 3, and 4 was significantly lower than in group 1. This is the first evidence that DKT prevents BT by reducing inflammatory reaction and maintaining intestinal integrity.

Abstract
The effects of Dai-kenchu-to (DKT), a Chinese medicine, on spontaneous activity of mouse small intestine were investigated. Experiments were carried out with tension recording and intracellular recording. DKT contracted mouse longitudinal smooth muscles in a dose dependent manner (0.1-10 mg/ml). Low concentration of DKT (0.1 mg/ml) did not contract the longitudinal muscles of mouse small intestine. DKT (0.1 mg/ml) inhibited contraction elicited by transmural nerve stimulation (TNS). DKT (1 mg/ml) evoked relaxation before contraction. The initial relaxation was abolished by Nomega-nitro-L-arginine (L-NNA). DKT (10 mg/ml)-induced contraction had two components: a transient rapid contraction and a following slow contraction. Atropine inhibited DKT (1 mg/ml)-induced contraction to about 50% of control. In the presence of atropine, tetrodotoxin (TTX) inhibited the contraction elicited by DKT (1 mg/ml) to about 80%. DKT depolarized the membrane and decreased the amplitude of pacemaker potentials recorded from in situ myenteric interstitial cells of Cajal (ICC-MY) with no alteration to the frequency, duration and maximum rates of rise in the presence of nifedipine and TTX. The same results were obtained in slow waves recorded from circular smooth muscle cells. These results indicate that DKT evoked both contraction and relaxation by releasing acetylcholine, nitric oxide and other excitatory neurotransmitters in mouse small intestine. DKT had no effects on pacemaker mechanisms and electrical coupling between ICC-MY and smooth muscle cells in mouse small intestine. The results also suggest that DKT may contract smooth muscles by depolarizing the membrane directly.

Abstract
BACKGROUND Postoperative intraperitoneal adhesions are the leading cause of intestinal obstruction, but the underlying mechanisms remain incompletely understood. The aim of the current study was to investigate the involvement of intestinal ischemia/reperfusion (I/R) injury in adhesion formation in rats. MATERIALS AND METHODS Rats were subjected to either a dusting of talc (15 mg/rat) over the entire small intestine or ischemia induced by clamping the superior mesenteric artery (SMA) for 30 min followed by reperfusion with or without talc dusting. On postoperative days 4, 7, and 14, the scores, lengths, and incidence of adhesions were evaluated. In addition, the contractile force of the jejunal muscle was measured at 0, 24, 48, and 96 h after the treatments using organ bath techniques under bethanechol-stimulated conditions. RESULTS Talc induced mild adhesions in rats. Although I/R injury alone did not produce adhesions, it markedly aggravated the talc-induced adhesions, with higher scores and longer adhesions on postoperative days 4, 7, and 14. In addition, I/R injury caused 75-88% suppression of the circular muscle contractile force and 35-52% suppression of the longitudinal muscle contractile force at 24 h after SMA occlusion. However, talc did not affect the contractions. CONCLUSIONS Intestinal I/R injury aggravated the talc-induced adhesions, and this consequence might be due to the functional suppression of jejunal muscle contractions. This finding suggests that intestinal ischemia is an important factor in the etiology of postoperative adhesions.

Abstract
BACKGROUND Post-operative ileus (POI) is a transient bowel dysmotility after operation. We have previously shown that laparotomy alone significantly delayed gastrointestinal (GI) transit, compared to anesthesia alone. The GI transit was further delayed after laparotomy plus intestinal manipulation. Dai-Kenchu-to (DKT), an herbal medicine, has been used for treating adhesive bowel obstruction in Japan. We studied whether DKT improves delayed GI transit after the operation, with or without morphine administration in rats. MATERIALS AND METHODS Under isoflurane anesthesia, POI was induced by laparotomy with intestinal manipulation. Immediately after the operation, the rats received 51Cr by gavage. Three hours after the operation, the rats were sacrificed and GI transit was estimated by calculating the geometric center (GC). DKT (120, 360, and 1,200 mg/kg) were administered by gavage after the operation, with or without morphine administration (1 mg/kg s.c.). A muscarinic receptor antagonist (atropine; 50 mug/kg), a 5HT3 receptor antagonist (ondansetron; 1 mg/kg) and a 5HT4 receptor antagonist (GR113,808; 3 mg/kg) were administered before the operation. Truncal vagotomy was performed preceding the operation. RESULTS Laparotomy with intestinal manipulation produced a significant delay in GI transit (GC = 2.93 +/- 0.16), compared to that of anesthesia alone (9.51 +/- 0.45). DKT at the dose of 360 mg/kg (GC = 3.77 +/- 0.10, P < 0.01) and 1,200 mg/kg (GC = 3.77 +/- 0.20, P < 0.01) significantly accelerated delayed GI transit induced by operation. Ondansetron, GR113,808, atropine, and truncal vagotomy abolished the stimulatory effect of DKT (360 mg/kg). When morphine was administered, GI transit was further reduced (GC = 1.97 +/- 0.10). DKT at the dose of 360 mg/kg (GC = 2.81 +/- 0.22, P < 0.05) and 1,200 mg/kg (GC = 2.87 +/- 0.23, P < 0.05) significantly improved delayed GI transit in morphine treated rats. CONCLUSIONS DKT accelerates delayed GI transit induced by intestinal manipulation with and without concomitant morphine administration. DKT treatment may be useful for the patients with POI.

Abstract
This study was conducted to evaluate the effect of Dai-kenchu-to on chlorpromazine-induced hypoperistalsis in mice. Oral administration of Dai-kenchu-to (30-300 mg/kg) dose-dependently improved small intestinal and distal colonic propulsion decreased by chlorpromazine (3 mg/kg, p.o.). Although the improvement of small intestinal propulsion due to Dai-kenchu-to was partially inhibited by atropine (1 mg/kg, s.c.), this action was completely inhibited by the concomitant administration of lorglumide (10 mg/kg, i.p.), a CCKA receptor antagonist. The distal colonic propulsion-improving effect of Dai-kenchu-to was abolished by atropine (1 mg/kg, s.c.). When the effects of the respective components of Dai-kenchu-to were evaluated, oral administration of Zanthoxylum Fruit improved both delayed small intestinal and distal colonic propulsion caused by chlorpromazine. On the other hand, Malt Sugar was effective against only delayed small intestinal propulsion. The action of Zanthoxylum Fruit was completely inhibited by atropine (1 mg/kg, s.c.), and the effect of Malt Sugar was inhibited by lorglumide (10 mg/kg, i.p.). These results demonstrated that Dai-kenchu-to improves chlorpromazine-induced hypoperistalsis via cholinergic systems and that Zanthoxylum Fruit is the main contributor to this action of Dai-kenchu-to. In addition, endogenous CCK due to Malt Sugar may also contribute to this effect of Dai-kenchu-to.

Abstract
The present study investigated the effects of the herbal medicine Dai-kenchu-to (DKCT) and its 4 individual ingredients on intestinal blood flow (IBF) in rats by laser Doppler flowmetry. Intraduodenal administration of DKCT (30, 100 and 300 mg/kg) increased IBF in a dose-dependent manner, whereas the mean arterial blood pressure was not affected. One of the ingredients in DKCT is dried ginger rhizome (150 mg/kg), whose main component is [6]-shogaol (2 mg/kg), both of which showed similar effects to those shown by DKCT, while the other ingredients in DKCT only slightly increased IBF or had no effect. The calcitonin gene-related peptide (CGRP) receptor antagonist, CGRP (8-37), completely abolished the hyperemia induced by DKCT, dried ginger rhizome and [6]-shogaol. However, the vasoactive intestinal polypeptide (VIP) receptor antagonist, [4-Cl-DPhe6, Leul7]-VIP, and atropine were less inhibitory than CGRP (8-37), and the substance P (SP) receptor antagonist, spantide, had no effect. The present study demonstrated that DKCT and one of its active components, [6]-shogaol, produced an increase in IBF which was mainly mediated by CGRP and suggests that DKCT may be useful in the treatment of intestinal ischemia-related diseases.

Abstract
The present study was conducted to clarify the effects of Dai-kenchu-to on accelerated small intestinal movement. We evaluated the effects of Dai-kenchu-to and its constituent herbs (dried ginger root, ginseng, zanthoxylum fruit, and malt sugar) on carbachol-accelerated mouse small intestinal transit, and contractions induced by low-frequency electrostimulation (ESC), KCl, or acetylcholine (ACh) using isolated guinea pig ileum. Dai-kenchu-to (10-300 mg/kg, p.o.) significantly improved carbachol-accelerated small intestinal transit in a dose-dependent manner. Using a concentration with the compounded rate for Dai-kenchu-to 300 mg/kg, carbachol-accelerated small intestinal transit was also significantly improved with a single dose of dried ginger root or ginseng. At a concentration of 3 x 10(-5) g/ml or less, Dai-kenchu-to, dried ginger root, and ginseng all inhibited ESC but not KCl- or ACh-induced contractions. However, at a higher concentration of Dai-kenchu-to (10(-4) g/ml) or zanthoxylum fruit (10(-5) g/ml or more) the ESC were enhanced. Both Dai-kenchu-to and dried ginger root at 10(-3) g/ml remarkably inhibited the KCl-induced contractions. These results indicate that Dai-kenchu-to improves accelerated small intestinal movement and that dried ginger root and ginseng may be involved in this effect. It is also thought that the mechanisms mainly involve the direct inhibition of smooth muscle but with a contribution from neural inhibition.

Abstract
The effects of both Dai-kenchu-to and PGF(2alpha) on intestinal and uterine motility were studied in anaesthetized rabbits with force transducers implanted in the jejunum, ileum and uterus. A single intraduodenal administration of Dai-kenchu-to (300 mg/kg) enhanced the intestinal motility but not the uterine motility. However, intravenous administration of PGF(2alpha) (20 microg/kg) enhanced both intestinal and uterine motility. The effects of Dai-kenchu-to on the spontaneous contraction and contractile response of the isolated rat uterine strips to oxytocin, PGF(2alpha) or ACh were also studied. Oral administration of Dai-kenchu-to at 300 mg/kg for one week had no effect on either the spontaneous contraction or the contractile response of the uterus. These results indicate that Dai-kenchu-to may exert stimulatory effects on intestinal motility, as PGF(2alpha), but has no effect on the uterine motility, suggesting a selective effect on the gastrointestinal tract. Hence, Dai-kenchu-to may be safer than PGF(2alpha) in the treatment of postoperative adhesive ileus in women. However, more studies are needed to determine whether Dai-kenchu-to could be administered to pregnant women.

Abstract
To clarify the contractile mechanism of Dai-kenchu-to, the effects of hydroxy beta-sanshool (an ingredient of Zanthoxylum fruit), Zanthoxylum fruit (a constituent herb of Dai-kenchu-to) and Dai-kenchu-to were studied in mucosa-free longitudinal muscle of guinea pig ileum. Hydroxy beta-sanshool at 10(-7)-10(-5) g/ml induced dose-related contractions accompanied by autonomous contraction and produced an initial contraction at a concentration of 10(-4) g/ml or more. The contraction induced by hydroxy beta-sanshool (10(-5) g/ml) was significantly inhibited by tetrodotoxin or the capsaicin-receptor antagonist capsazepine. Although atropine or the substance P antagonist spantide tended to inhibit the contraction, a combination of atropine and spantide almost abolished the contraction by hydroxy beta-sanshool. The P2-purinoceptor antagonist pyridoxal-phosphate-6-azophenyl-2',4'-disulphonic acid did not affect hydroxy beta-sanshool-induced contraction in the presence or absence of spantide. The tonic contractions by Zanthoxylum fruit (2 x 10(-4) g/ml) and Dai-kenchu-to (10(-3) g/ml) were significantly inhibited or tended to be inhibited by atropine, spantide, tetrodotoxin or capsazepine and were remarkably suppressed by the combination of atropine and spantide. These results suggested that acetylcholine release from intrinsic cholinergic nerves and tachykinins from sensory neurons are involved in the contractions induced by hydroxy beta-sanshool and that tachykinins may be involved in the atropine-resistant contraction by Dai-kenchu-to.

Abstract
The mechanisms by which Dai-kenchu-to (TJ-100), a kampo medicine, enhances gastrointestinal motility was investigated using isolated guinea pig ileum. TJ-100 induced contractions accompanied by autonomous contraction at a concentration of more than 3 x 10(-4) g/ml in a dose-related manner. The TJ-100-induced ileal contraction was suppressed by atropine and tetrodotoxin, but not by hexamethonium. This effect was partially suppressed in the presence of high concentrations of ICS 205-930, a serotonin 4 (5-HT4) receptor antagonist. In addition, TJ-100 showed an acetylcholine (ACh)-releasing action in the smooth muscle tissues of ileum. These results suggest that contractile response induced by TJ-100 is partially mediated by ACh released from the cholinergic nerve endings and that 5-HT4 receptors would be involved in the effect of TJ-100.
