Amis:ST25(Chonchu) and ST37(Sanggoho) are usually used acupoints to management several disease which induced to abnormal intestinal motility as diarrhea, constipation. Colonic transit time by radio opaque marker is able to study easily and useful method for evaluation of colonic motility. The aim of this study was to assess the effect on colonic transit time by manual acupuncture or electroacupuncture stimulation of ST25, ST37 in normal adult. Method: Colonic transit time, including Rt colon, Lt colon, rectosigmoid colon was measured by radio opaque marker in 11 normal adults. Colon transit time was measured before stimulation and after stimulation on ST25, ST37 by manual acupuncture and electroacupuncture. Each person was treated manual acupuncture or electroacupuncture stimulation for 3 days before colonic transit time measurement with 1 week interval. Result: Colon transit time before stimulation was measured $10.60{\pm}12.11$, $3.92{\pm}7.72$, $3.27{\pm}6.37$, $3.41{\pm}5.57$ hours total colon, Rt colon, Lt colon, rectosigmoid colon, respectively. Colon transit time after manual acupuncture is measured $10.48{\pm}12.35$, $3.72{\pm}7.52$, $3.37{\pm}6.76$, $3.39{\pm}5.84$ hours total colon, Rt colon, Lt colon, rectosigmoid colon, respectively. Colon transit time after electroacupuncture stimulation is measured $10.30{\pm}13.21$, $3.92{\pm}8.02$, $3.07{\pm} $, $3.31{\pm}5.49$ hours total colon, Rt colon, Lt colon, rectosigmoid colon, respectively. Significant change was observed Lt colon transit time after electroacupuncture as compared before acupuncture(P<0.05). Conclusion: Theses results suggest that manual acupuncture and electroacupuncture of ST25, ST37 in normal adults does not change colonic transit time.

본 논문은 딥러닝을 이용하여 대장통과시간(Colon Transit Time, CTT) 검사를 위한 단순복부 X-Ray 영상에서 방사선 비투과성 표지자(Radio-opaque Marker)를 자동으로 검출하는 기법을 제시한다. 대장통과시간 검사는 대장의 운동질환을 평가하는데 있어 가장 기본적인 방법으로 특히 만성 변비증 환자의 병태생리에 따른 유형 분류와 치료 계획을 설정하는데 큰 도움을 주고 있으며, 내과적 또는 외과적 치료 후 평가에도 유용한 검사이다. 대장통과시간 검사는 방사선 비투과성 표지자가 내재되어 있는 캡슐을 복용한 뒤 주기적으로 단순복부 X-Ray 촬영을 통해 구간별로 남아있는 표지자의 수를 세고, 이를 통해 구역별 통과시간을 측정한다. 이 과정에서 판독의가 직접 표지자의 위치 및 개수를 세기 때문에 많은 시간이 필요하게 된다. 따라선 본 논문에서는 이러한 단점을 보완하기 위해 딥러닝 기법을 사용하여 X-Ray 영상 내에서 표지자의 위치를 자동 파악하는 기법을 제시한다.

Colonic transit time plays an important role in creating a disease category and treatment plan in patients with chronic constipation or bowel movement problem. The aim of this study is to establish normal colon transit time using Kolomark, a radiopaque marker in dogs. The transit time of Kolomark in colon was measured every 2, 4, 8, 12, 24, 48 hours in 11 healthy Beagle dogs with oral administration of the marker. Kolomark began to appear in colon after 4 hours from administration and the largest number of Kolomark in colon was observed after 12 hours. Then, after 24 hours, some quantity of Kolomark was found but Kolomarks were all eliminated from the colon after 48 hours. The mean emptying time of Kolomark was 28.36 hours. Based on this study, the normal range of colon transit time in dogs was established by using the Kolomark, and it could be used as reference data for objective evaluation of constipation in canine patients.

This study was performed to investigate effects of raw sea tangle products on idiopathic constipation. A total of thirty-eight women participated voluntarily in this study. They were placed into one of four groups by their total colonic transit time (TCTT) to make the four groups have the same TCTT. In the first trial, the subjects in Control group were fed 3 times of 150 mL of mineral water per day for 2 weeks, those in +Control group were fed a kind of stool softener as well as the same mineral water for 3 times, those in STT group were fed 3 times of 150 mL of sea tangle tea and those in STB group were fed 3 times of 150 mL of sea tangle beverage. After 6 weeks, a second trial was performed for another 2 weeks. Although the TCTT of the group exposed to of KolomarkTM was not significantly reduced, the subjects in STT group answered that their evacuation activities were significantly improved; evacuation frequency was increased, stool hardness was reduced, evacuation straining was lessened, stool amount was increased, incomplete sense of evacuation was lessened, and major evacuation time was improved like those in +Control group. The results imply that it is worthy to develop some products of raw sea tangle such as STT, which are effective in treating or preventing constipation.

Purpose: The aim of this study was to evaluate the correlation among descriptions regarding one's stool, Bristol stool form scale and colon transit time (CTT) in children with gastrointestinal symptoms, along with the clinical significance of Bristol stool form scale. Methods: 489 patients treated in the pediatric department of Severance hospital with gastrointestinal symptoms between May 2002 to May 2004 were included. We analyzed their age, sex, verbal descriptions of stool, Bristol stool form types, and CTT measured by Metcalf's method. Results: 116 children were under 5 years of age, 202 children between 5.1~10, and 171 children 10 years of age or older. Their mean age was $8.2{\pm}3.9years$. Stools were described as loose in 65 children (13.3%), normal in 221 (45.2%), hard in 188 (38.4%), and mixed (loose+hard) in 15 (3.1%). According to Bristol stool form scale, 57 children(11.7%) were classified as type 1, 66 (13.5%) as type 2, 203 (41.5%) as type 3, 109 (22.3%) as type 4, 36 (7.4%) as type 5, 18 (3.7%) as type 6, and 1 (0.2%) as type 7. Their mean CTT was checked $35.9{\pm}19.5hours$. Though no significant relationship was observed between age and CTT (p=0.4), a significant relationship was noted among patient's stool description, Bristol stool form scale and CTT (p<0.001). However, concordance between stool description and Bristol stool form was relatively low in the loose stool group (29%) and normal stool group (37%) while high in the hard stool group (87%). Conclusion: Bristol stool form scale could be used in the estimation of CTT in clinical practice.

The simulation of electric field distribution of discharge tube with globular $Al_2O_3$ and the removal characteristic of Escherichia coli by the discharge tube with globular $Al_2O_3$ were estimated. The removal characteristic of Escherichia coli was related to the input voltage because the electric field is increased according to input voltage. As the passing amount of test water in discharge tube is increased, the removal ratio of Escherichia coli was increased because passing numbers of electric field section is increased. As the particle size of globular $Al_2O_3$ increased, the removal time of Escherichia coli was shortened due to the dielectric polarization of globular dielectric $Al_2O_3$. Also, the removal efficiency of Escherichia coli for the discharge tube with globular dielectric $Al_2O_3$ was higher than that of the discharge tube without it.

In this study, we aimed to investigate the effect of Chinese gooseberry (kiwi)-based products on the improvement of intestinal function and constipation. In this study, 21 participants with no underlying disease and complaining of subjective constipation symptoms were selected. Through a pre-experimental design, the main effects, including the colon stagnation score and colon transit time, were assessed after the consumption of Chinese gooseberry (kiwi)-based products. To evaluate the side effects of this product, a subjective constipation assessment test was performed to analyze the degree of constipation improvement at an individual level. The results for the main effects revealed that the number of constipation groups was statistically significantly decreased, and the colon stagnation score and colon transit time were also reduced. Additionally, the participants' subjective constipation assessment test revealed a significant improvement in both intestinal function and bowel activity before and after the consumption of Chinese gooseberry (kiwi)-based products. Similar to the previously known kelp-, lactobacillus-, and fiber-based products, we showed that Chinese gooseberry (kiwi)-based products exert a significant effect on the improvement of the intestinal function and constipation. Furthermore, the results of this study provide valuable information for the development of healthy food products in the future that can help improve bowel movement. Moreover, Chinese gooseberry (kiwi) used in this study is not a functional food and is easily accessible. However, this study has several limitations as it is based on a pre-experimental design. Therefore, studies on randomized experimental and control groups are needed in the future.

The effects of single cells of carrot or radish on the fecal excretion, mineral absorption rate and structure of small intestine and colon were investigated in rats fed 5% single cell diet for 4 weeks. Carrot contained 28.76% of total dietary fiber and 21.45% of insoluble dietary fiber, and radish contained 23.14% of total dietary fiber and 16.77% of insoluble dietary fiber on a dry weight basis. Total dietary fiber contents of the single cell were 44.68% for carrot, 48.0% for radish. Absorption rates of magnesium were higher in the carrot and radish single cell groups than the other groups. Cellulose significantly increased fecal weight and weight of small intestine. The consumption of cellulose and single cells decreased digestibility of lipid. The length of colon were longer in the carrot and the radish group than the other groups. Scanning electron microscopy studies showed that small intestine microvilli with leaf-shaped were seen in cellulose and single cell fed groups. These results suggest that the diet containing 5% single cells of carrot or radish increases the digestibility of dietary fiber, weight gain, and fecal output and shorten the gastrointestinal transit time.

I. Introduction : The constipation is one of the common gastrointestinal symptoms seen in the clinical practice. When people come to the clinic complaining of the constipation, it is generally one of the cases of infrequent, painful or difficult evacuation as well as the hardened feces and unsatisfactory evacuation sense. Since the constipation is heavily influenced by dietary habit as well as the social and medical environment, the diagnostic radiology is useful to establish the objective and standardized definition in consideration of those various factors before diagnosis and treatment of the constipation patient. This paper describes the study of such diagnosis. II. Main Subject : Testing of CTT (colon transit time) is key study of the colon performance. CTT is very helpful in classifying the pathologic physiological types and defining the treatment plan for the chronic constipation. The study methods include using the radipaque marker, multiple marker technique and scintigraphic measurement. The defecography is the functional radiologic examination a that provides not only the anatomical information of anorectal but also performance of the pelvic floor and rectal change during evacuation. Study of dynamic movement of the anorectal during evacuation is helpful for diagnosis and treatment planning as well as follow-up testing for the constipation patient. One of the issues essential for the case history is the thorough observation of whether the patient shows the psychic psychological symptoms such as the behavior disorder or emotional disturbance. In that case, the decision must be made whether or which type of medication is needed for such psychiatric problem. III. Conclusion : The main causes of the constipation are insufficient intake of fiber or liquid. The key objective of such tests is to check etiology of the constipation. In general, the radiological examination does not provde the colon or anorectal performance information. It is envisaged that this study will provide the information to decide the testing and treatment plans and predict the prognosis of the patient by classifying the pathologic physiological types.
