  • The functional dyspepsia is a complex disease reaction that ocurs due to the presence of various factors and its pathophysiology has not been clearly verified until now. This disease is diagnosed after the organic diseases are ruled out. Therefore, the main treatments are limited down to compensating for revealed symptoms through exercising the supportive care. The international prevalence of the functional dyspepsia under the Rome I criterior is approximately 25%. For the cases of Koreans, there are very omnifarious symptoms in gastrointestinal disorders and the medical vocabularies which describe the diagnostic standard are not closely associated with the daily vocabularies, thus there would be a lot of restrictions to directly apply the Rome II criterior. However, the Korean Society of Gastrointestinal motility had decided to promote the use of the international standardized Rome II criterior in order for Korea to be comparable to the clinical studies from the other nations. There should be more extensive studies to differentiate the definitions of symptom descriptions from Korea to foreign countries. The extended researches concerning the pathophysiology are highly recommended which in return, would help enabling the reliable treatment techniques for this disease.

  • Motilitone$^{(R)}$ (DA-9701) is a new herbal drug that was launched for the treatment of functional dyspepsia in December 2011 in Korea. The heterogeneous symptom pattern and multiple causes of functional dyspepsia have resulted in multiple drug target strategies for its treatment. DA-9701, a compound consisting of a combination of Corydalis Tuber and Pharbitidis Semen, has being developed for treatment of functional dyspepsia. It has multiple mechanisms of action such as fundus relaxation, visceral analgesia, and prokinetic effects. Furthermore, it was found to significantly enhance meal-induced gastric accommodation and increase gastric compliance in dogs. DA-9701 also showed an analgesic effect in rats with colorectal distension induced visceral hypersensitivity and an antinociceptive effect in beagle dogs with gastric distension-induced nociception. The pharmacological effects of DA-9701 also include conventional effects, such as enhanced gastric emptying and gastrointestinal transit. The safety profile of DA-9701 is also preferable to that of other treatments.

  • 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.

  • Purpose: Malnutrition is a common feature in critically ill children. Enteral nutrition (EN) is the main strategy to nutritionally support critical ill children, but its use can be hindered by the development of intolerance. The study aimed to assess the effectiveness and safety of amoxicillin/clavulanate (A/C) to treat EN intolerance. Methods: We retrospectively evaluated patients admitted to the pediatric intensive care unit from October 2018 to October 2019. We conducted a case-control study: in the first 6 months (October 2018-April 2019) we implemented the nutritional protocol of our Institution with no drug, whereas in the second half (May 2019-October 2019) we employed A/C for 1 week at a dose of 10 mg/kg twice daily. Results: Twelve cases were compared with 12 controls. At the final evaluation, enteral intake was significantly higher than that at baseline in the cases (from 2.1±3.7 to 66.1±27.4% of requirement, p=0.0001 by Wilcoxon matched-pairs signed rank test) but not in the controls (from 0.2±0.8 to 6.0±14.1% of the requirement, p=NS). Final gastric residual volume at the end of the observation was significantly lower in the cases than in the controls (p=0.0398). The drug was well tolerated as shown by the similar safety outcomes in both cases and controls. Conclusion: Malnutrition exposes critically ill children to several complications that affect the severity of disease course, length of stay, and mortality; all may be prevented by early EN. The development of intolerance to EN could be addressed with the use of A/C. Future prospective clinical trials are needed to confirm these conclusions.

  • QT prolongation is an electrocardiographic change that can lead to lethal arrhythmia. Acquired QT prolongation is known to be caused by drugs and electrolyte abnormalities. We report three cases in which the prolonged QT interval was improved at the time of operation by briefly discontinuing the drugs suspected to have caused the QT prolongation observed on preoperative electrocardiography. The QTc of cases 1, 2, and 3 improved from 518 to 429 ms, 463 to 441 ms, and 473 to 443 ms on discontinuing the use of a gastrointestinal prokinetic agent, a proton pump inhibitor, and a molecular targeted drug, respectively. These cases were considered to have drug-induced QT prolongation. We reaffirmed that even drugs administered for conditions unrelated to cardiac diseases can have adverse side effect of QT prolongation. In conclusion, our cases indicate that dental surgeons should be aware of the dangerous and even potentially lethal side effects of QT prolongation. For safe oral and maxillofacial surgery, cooperation with medical departments in various fields is important.

  • 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.

  • Although there is a wide range of diseases caused by gastric acid reflux and the number of cases is on the rise, it is difficult for the laryngologist to make the correct diagnosis. The treatment for laryngopharyngeal reflux can be grouped into 3 categories - changes in lifestyle, medication, and surgery. The medication used to treat laryngopharyngeal reflux are prokinetic agents and acid supressive agents such as antacids, H2 blockers, and PPIs(Proton pump inhibitor). Rabeprazole sodium($Pariet^{\circledR}$) is a newly developed agent belonging to the PPI group, but in contrast with the existing drugs such as omeprazole, lansoprazole, pantoprazole, has a low dependency on CYP2C19 during the metabolic cycle. Thus, it is known to have a quick but fixed antiacid effect and less individual differences. We analyzed 2166 patients from 32 hospitals who were prescribed $Pariet^{\circledR}$ from May, 2001 to April, 2002. The patients were divided into 4 groups according to the duration of treatment - Group 1: 1-14 days, Group 2: 15-28 days, group 3: 29-56 days, Group 4: more than 56 days. The cases were then analyzed for improvement of 8 symptoms(heart bum, regurgitation, chronic cough, hoarseness, globus sensation, chronic throat clearing, sore throat, and dysphagia), improvement on laryngoscope, usefulness to the doctor, and complication development. Of the total of 2116 patients, 1627(75.1%) cases showed at least 50% improvement of symptoms and the amount of improvement increased according to the duration of medical treatment. Most of the patients showed objective improvement on the laryngoscope, with 32.9% showing significant improvement and 38.7% showing moderate improvement. 37.6% of the doctors questioned replied that $Pariet^{\circledR}$ was very useful and 50.3% said it was useful, showing that most were satisfied with the treatment results. The complications known to develop after taking PPI are headache, nausea, diarrhea, abdominal pain, constipation, dizziness, fatigue, and of these, only a small percentage of the patients complained of mild headache. $Pariet^{\circledR}$ has shown to be a relatively safe and effective drug for the treatment of laryngopharyngeal reflux.

  • Obejectives : The purpose of this study was to investigate the effects of Yijin-tang on pacemaker potentials of small intestinal interstitial Cells of Cajal (ICC). Methods : To dissociate the ICC, we used enzymatic digestions from the small intestine in mice. The electrophysiological whole-cell patch-clamp configuration was used to record pacemaker potentials in the cultured ICC and the in vivo effects of Yijin-tang on GI motility were investigated by calculating percent intestinal transit rates (ITR). Results : 1. The ICC generated pacemaker potentials in the murine small intestine. Yijin-tang produced membrane depolarization with concentration-dependent manners in the current clamp mode. 2. Pretreatment with a Ca2+ free solution and thapsigargin, a Ca2+-ATPase inhibitor in the endoplasmic reticulum, stopped the pacemaker potentials. In the case of Ca2+-free solutions and thapsigargin, Yijin-tang did not induce membrane potential depolarizations. 3. U73122, a phospholipase C (PLC) inhibitors, blocked the Yijin-tang-induced membrane potential depolarizations. However, U73343, an inactive PLC inhibitors, did not block. 4. In the presence of protein kinase C (PKC) inhibitors, staurosporine or Rottlerin, Yijin-tang depolarized the pacemaker potentials. However, in the presence of Go6976, Yijin-tang did not depolarize the pacemaker potentials. 5. In mice, intestinal transit rate (ITR) values were significantly and dose-dependently increased by the intragastric administration of Yijin-tang. Conclusions : These results suggest that Yijin-tang can modulate the pacemaker activity of ICC through an internal/external Ca2+ and PLC/PKC-dependent pathway in ICC. In addition, Yijin-tang is a good candidate for the development of a prokinetic agent.

  • 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.

  • 이비인후과 영역에 있어서 위산 역류에 의한 질환의 진단은 쉽지 않고 분명하지 않은 점이 많지만, 병변의 영향은 광범위하며, 실제로 역류에 의한 증상을 가지고 내원하는 환자도 증가하는 추세이다. 인후두역류질환의 치료는 크게 생활습관의 변경, 약물복용, 항역류수술로 나눌 수 있으며, 사용약제는 크게 두 부류로 나누는데, 제산제, H2 수용체 차단제, PPI(Proton Pump Inhibitor) 제제와 같은 산억제 약물군과 Prokinetic 약물군이다. Rabeprazole sodium(Pariet(R))은 PPI 제제에 해당하는 약제로 기존의 omeprazole, lansoprazole, pantoprazole과는 달리 대사 과정 중 CYP2C19에 대한 의존도가 낮아, 개체 간 차이가 적고 빠르고 일정하게 산분비 억제 효과를 나타내는 것으로 알려져 있은 약물이다. 2001년 5월부터 2002년 4월까지 32개 병원에서 Pariet(R) 를 복용한 2166명의 환자를 대상으로 분석하였다. 복용기간에 따라 4군(1군;1-14일, 2군;15-28일, 3군;29-56일, 4군:57일 이상)으로 나누었으며, 8가지 증상(Heart burn, Regurgitation, Chronic cough, Hoarseness, Globus sensation, Chronic throat clearing, Sore throat, Dysphagia)에 대한 호전 여부 및 후두내시경상 개선 정도, 의사에 의한 유용도 평가, 부작용 발생 여부에 대해 연구하였다. 증상개선율 50%이상을 치료 반응군으로 했을때 전체 2166명중 1627명(75.1%)에서 증상의 호전을 보았으며, 이는 복용기간이 길수록 증가하였다. 후두 내시경상 개선 정도는 현저한 개선이 32.9%, 중등도 개선이 38.7%로 대부분 환자에서 객관적인 병변의 호전을 보였으며, 유용도 평가에서는 매우 유용이 37.6%, 유용이 50.3%로 치료효과에 대한 만족도도 높은 것을 알수 있었다. PPI 제제의 부작용으로 보고되고 있는 두통, 오심, 설사, 복통. 변비, 어지럼증. 피곤 중. 소수의 환자가 두통을 호소하였으나, 그다지 심각한 정도는 아니었다. 인후두역류증 치료제로서 Pariet(R) 는 비교적 안전하고 효과가 높은 약물임이 임상 연구 결과 밝혀졌기에 보고하는 바이다.
