  • 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.

  • 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.

  • Sennoside A (erythro) and sennoside B (threo) are dianthrone glycosides and diastereomers. We investigated their abilities to prevent the gastric lesions associated with diseases, such as, gastritis and gastric ulcer. To elucidate their gastroprotective effects, the inhibitions of $HCl{\cdot}tOH$-induced gastritis and indomethacin-induced gastric ulcers were assessed in rats. It was observed that both sennoside A and sennoside B increased prostaglandin $E_2$ ($PGE_2$) levels and inhibited $H^+/K^+$-ATPase (proton pump). In a rat model, both compounds reduced gastric juice, total acidity and increased pH, indicating that proton pump inhibition reduces gastric acid secretion. Furthermore, sennoside A and B increased $PGE_2$ in a concentration-dependent manner. In a gastric emptying and intestinal transporting rate experiment, both sennoside A and sennoside B accelerated motility. Our results thus suggest that sennoside A and sennoside B possess significant gastroprotective activities and they might be useful for the treatment of gastric disease.

  • P-methoxycinnamic acid and 3,4,5-trimethoxycinnamic acid are the compounds found in Polygalae Radix, the root of Polygala tenuifolia Willdenow, and have been reported to have hepatoprotective and anti-neurodegenerative effects. On the other hand, there are no reports of their effects on gastric lesions. This study examined the inhibitory effects of cinnamic acids, including p-methoxycinnamic acid, 3,4,5-trimethoxycinnamic acid, and 8 compounds (cinnamic acid, 2-(trifluoromethyl) cinnamic acid, 3-(trifluoromethyl) cinnamic acid, trans-4-(trifluoromethyl) cinnamic acid, 4-(dimethylamino) cinnamic acid, 3,4-(methylenedioxy) cinnamic acid and 3,4-dihydroxycinnamic acid), which were selected based on their presence in medicinal herbs and molecular weight, against gastric lesions. Animal models were used to confirm the protective effects on acute gastritis caused by the administration of HCl/EtOH. Gastric acid inhibition was examined by an acid-neutralizing test and the proton pump ($H^+/K^+$-ATPase) inhibiting activity. In addition, antioxidant tests were performed and the gastric emptying rate was determined. The results showed that cinnamic acid, p-methoxycinnamic acid, and 3,4,5-trimethoxycinnamic acid had an inhibitory effect on gastric lesions.

  • This study was performed to evaluate the effect of acupuncture on gastric motility in dogs with radiography and ultrasonography. All experimental dogs were fed with the soup with barium (3% W/V), and thereafter gastric emptying time(GET) was measured with radiography and ultrasonography with Bolondi's method. The acupoints were CV-12, PC-6, ST-36 and BL-21 in this experiment. On these acupoints, electroacupunctral stimulation(15 MHz, continous wave) was applied for 20 minutes. The results were as follows: In the control group, normal GET was 70-85 minutes with ultrasonography, and 110-130 minutes with radiography. In acupuncture stimulation groups, there was no effect of gastric motility in CV-12, PC-6, and 57-36, whereas there was significant stimulating effect of gastric movement in BL-21 with ultrasonography (P < 0.05) and radiography (P < 0.01). Above these results, it is concluded that acupunctural stimulation of BL-21 was more effective in gastric motility compared to those of CV-l2, PC-6 and ST-36.

  • 개에서 이물, 신생물, 유문동비후, 위수술, 전해질불균형, 위확장성 염전 등에 의한 비정상적인 위 배출시간은 임상에서 소화기 질환으로 중요하다. 그러므로 위장관 운동이상에 대한 정확한 진단을 위하여 정상적인 위장관 운동시간에 대한 자료가 필요하다. 이 연구의 목적은 개에서 기존의 BIPS를 이용하는 검사 방식이 아닌 국내에서 개발한 방사선 비투과성 Kolomark를 이용한 위배출시간 검사에 대한 임상적 유용성에 대한 기초자료를 제공하기 위한 것이다. Beagle 9마리가 이번 실험에 사용되었으며 평균 체중 평균 10.3kg이며 평균 2.5살이었다. 검사를 위해 12시간 금식을 시행하였으며 화학적 보정은 하지 않은 채 검사 직전 하루 사료급여량의 25%용량에 Kolomark 1개의 capsule과 함께 급여하였고 2, 4, 8, 12시간 때 Ventrodorsal, Right lateral자세로 촬영하였다. 관심판독부분은 분문에서 위유문부까지의 위장 전체를 관찰하였으며 분석방법으로는 각 시간대별로 위장 내에 남아있는 Kolomark를 카운트하여 비모수검정인 Friedman 검정방법을 이용하여 P값이 0.05 미만인 경우를 유의한 것으로 판정하였다. 구강으로 Kolomark를 섭식 후 위에서 소장으로 완전히 Kolomark가 빠져나가는데 걸리는 평균시간은 7.55시간이었다. 이번 연구에서 성숙한 개에서 음식물 투여 후에 나타나는 위장관 통과시간을 Kolomark를 이용하여 정상적인 위장관 운동시간에 대한 기초자료가 되리라 판단된다.

  • 목적: 최근 조기위암 환자가 증가하기 때문에 수술 후 환자의 영양상태 개선을 포함한 삶의 질에 많은 관심이 모아지고 있다. 그러나 원위부 위절제 후 많이 이용되고 있는 Billroth-I, II 및 Roux-en-Y 술식은 남은 위의 작은 용량과 십이지장 우회에 따른 철분, 지방, 칼슘, 카로틴 등의 흡수 장애 등의 단점이 있다. 이를 보완하고자 저자들은 위 원위부 절제 후 소장낭을 저장소 역할을 하게 하고, 또한 십이지장과 문합하여 음식물이 생리적 방향으로 통과하도록 공장낭 간치술을 시행하였다. 대상 및 방법: 2001년 3월부터 2004년 2월까지 가톨릭의과대학 성가병원 외과에서 위암으로 원위부 절제를 시행한 196예를 공장낭 공장낭 간치술(JPI 군, n=100), B-I 군(n=29), B-II군(n=67)으로 나누어, 혈액 및 생화학적 검사의 변화, 몸무게를 포함한 영양학적 변화 및 위내시경 소견과 위 배출시간을 분석하였다. 결과: 환자들의 체중은 3군 모두 술 후 6개월에 최대로 감소된 후 회복되는 경향을 보였으며, 술 후 6개월, 1년, 2년째의 체중 감소율이 JPI군이 $5.14\%,\;3.01\%,\;2.37\%$로 B-I 군의 $8.41\%,\;6.69\%,\;5.90\%$B-II 군의 $7.50\%,\;7.65\%\;5.86\%$에 비해 의의있게 작았다(P=0.011, P=0.000, P=0.013). 검사실 소견은 술 후 6개월에 총 단백이 JPI 군이 B-I과 B-II 군보다 더 높았으며, 특히 1,2기 위암 환자의 경우 술 후 1년째 총 단백과 알부민이 JPI군에서 의의있게 높았다. 그러나 빈혈과 관련된 검사 칼슘, 인, 콜레스테롤, 트리글리세라이드 등에서는 3군 간의 차이는 관찰되지 않았다. 술 후 6개월, 1년, 2년째의 $\^{99m}$Tc-반 고형식(샌드위치)를 이용한 위 배출시간은 JPI 군이 102.5분, 83.1분, 58.1분, B-I 군이 95.5분, 92.0분, 58.5분, B-II 군이 53.9분, 69.1분, 50.2분으로 B-II 군이 가장 빠르고, JPI군이 가장 느리게 관찰되었다. 또한 위 내시경 검사 상 술 후 6개월째 정밀관찰이 불가능한 음식 저류가 JPI 군에서 가장 많았으나 시간이 지나면서 호전되는 것을 관찰하였다. 결론: 공장낭을 이용한 간치술은 기존 술식보다 1시간 정도 수술시간이 더 걸리고, 수술 후 초기에 위 배출시간이 지연되는 경향이 있지만, 몸무게를 포함한 영양학적인 면을 고려할 때, 장기 생존이 기대되는 제 I, II기 위암 환자에게 적용될 수 있는 또 하나의 좋은 재건 술식이라고 생각한다.

  • Purpose: Delayed gastric emptying usually manifests as gastric food retention. This study aimed to evaluate the incidence of gastric food retention after distal gastrectomy with gastrojejunostomy in gastric cancer patients and identify the risk factors for its development. Materials and Methods: We retrospectively enrolled 245 patients who underwent distal gastrectomy with gastrojejunostomy for gastric cancer at Boramae Medical Center between March 2017 and December 2019. We analyzed the presence of gastric food residue via computed tomography (CT) scans at 3 and 12 months postoperatively and analyzed the risk factors that may influence the development of gastric food retention. Results: CT scans were performed on 235 patients at 3 months and on 217 patients at 12 months postoperatively. In the group that received closure of Petersen's space, the incidence of gastric food retention was significantly low as per the 3- and 12-month postoperative follow-up CT scans (P=0.028 and 0.003, respectively). In addition, hypertension was related to gastric food retention as per the 12-month postoperative follow-up CT scans (P=0.011). No other factors were related to the development of gastric food retention. In the multivariate analysis, non-closure of Petersen's space (hazard ratio [HR], 2.54; 95% confidence interval [CI], 1.20-5.38; P=0.010) was the only significant risk factor for gastric food retention at 3 months postoperatively, while non-closure of Petersen's space (HR, 2.81; 95% CI, 1.40-5.64; P=0.004) and hypertension (HR, 2.30; 95% CI, 1.14-4.63; P=0.020) were both significant risk factors for gastric food retention at 12 months postoperatively. Conclusions: Closure of Petersen's space has an effect on decrease the incidence of gastric food retention after distal gastrectomy with gastrojejunostomy in gastric cancer patients.

  • Transhiatal gastric transposition was performed in two case of long gap esophageal atresia without tracheoesophageal fistula. The patients were a 12 months old female and an 18 months old male. Stamm type gastrostomies were performed at other hospitals in both cases. The stomach was mobilized preserving the right gastric artery, the right gastroepiploic artery and spleen. A portion of the proximal and the distal esophageal segment were excised by transcervical and transhiatal route, respectively. The mobilized stomach was pulled up to the neck through the esophageal hiatus and posterior mediastinum. The esophagogastrostomy, the only one anastomosis of this procedure, was performed in the neck. There was no clinical evidence of anastomotic leakage, stricture, regurgitation, difficulty of gastric emptying, hoarseness or respiratory problem. Transhiatal gastric transposition seems to be a safe and easy alternative surgical procedure for esophageal replacement in long gap esophageal atresia.
