Background and Purpose : We were to investigate whether simple and electric acupuncture can affect the colonic transit time in both normal persons and chronic constipation patients. Methods: Twenty one volunteers were divided into two groups; first, normal control group(N=12) who had normal defecation habits, second, chronic constipation group(N=13). Before acupuncture, colonic transit time was checked using radio-opaque markers. Then simple acupuncture was done at four acupoints(both ST36, LI4) and maintained for 15 minutes during 4 days. Electric acupuncture was done using same methods except for applying 2Hz electrical stimulation. Result : In the normal group, after simple acupuncture, each transit time in the total, right, left was not changed statistic significance compared to pre-acupuncture(P>0.05), but which of rectosigmoid colon shortened statistic significance(P<0.05). After Electric acupuncture, transit time of right colon was shortened(P<0.05), and extended(P>0.05) in rectosigmoid colon compared to pre-acupuncture and simple acupuncture. In constipation group, after simple acupuncture, only rectosigmoid colonic transit time shortened statistic significance compared to pre-acupuncture(P<0.05). After electric acupuncture, also the transit time of rectosigmoid colon was shortened statistic significance compared to pre-acupuncture(P<0.05), but not to simple acupuncture(P>0.05). Conclusion : In normal persons without constipation, acupuncture affect the colonic transit time differently to the methods of it. In chronic constipation group, simple and electric acupuncture only reduces the rectosigmoid colonic transit time statistically significant(P<0.05).

We undertook this study to investigate the effects of acupuncture and electroacupuncture on colonic transit time in old age constipation persons. Twenty three volunteers were old age constipation persons(mean age 69.72±2.43 years, mean defecation rate 1.83±0.41/week). Before acupuncture was only to check the radio-opaque markers transit time all the way through gastrointestinal tract. Simple acupuncture was to apply acupuncture therapy for three days. The fourth acupoints(both ST.25, TE.6) were selected and the needle was kept for 15 minutes. Electroacupuncture was same as the simple acupuncture except for applying 2Hz electrical stimulation. After Then we compare with three method Each transit time in the whole colon, right colon, left colon and rectosigmoid colon were checked in the order of before acupuncture, simple acupuncture, and electroacupuncture stimulation. In the before acupuncture stimulation, the transit time in each part of colon was as follows 19.48±1.76 32.74±2.69 25.61±2.13 76.62±7.95 hours. Simple acupuncture stimulation, the transit time was 17.47±1.10 33.10±1.87 24.12±1.65 74.87±3.91 hours. Compared with before acupuncture stimulation, the transit time was significantly shortened(P<0.05), especially in right colon transit time of simple acupuncture stimulation was significantly shortened(P<0.05). Electroacupuncture stimulation, was 16.32±1.97 32.91±2.48 21.53±1.94 71.59±2.82. Compared with the previous two trial, transit time in right colon and rectosigmoid colon were significantly shortened(P<0.05). Acupuncture and electroacupuncture stimulation change on the right colonic transit time in old age constipation persons and rectosigmoid colonic transit time was changed as electroacupuncture stimulation. In other words, old age constipation persons who suffer chronic constipation, acupuncture and electroacupuncture stimulation reduces the total colonic transit time.

목적: 현재 소화기 증상이 없고 정상적인 배변 양상과 습관을 갖고 있으며 과거력상 만성적인 소화기 계통의 질환이 없었던 정상 성인에게 대장운동과 관계있다고 알려진 천추와 상거허에 침자극하고 대장 통과시간의 변화를 관찰하고자 하였다. 방법: 정상 성인 11명의 침자극전 대장 통과시간을 방사선 비투과성 표지자인 Sitzmarks capsule을 사용하여 우측 및 좌측 대장과 직결장, 전대장 통과시간 등으로 나누어 측정한후 대장의 하합혈인 상거허와 복모혈인 천추에 단순유침 15분 및 전침으로 침자극하고 같은 방법으로 대장 통과시간을 측정하여 비교하였다. 결과: 침자극전의 대장 통과시간 측정은 전대장 통과시간이 $10.60{\pm}12.11$시간 이었으며 우측 및 좌측 대장과 직결장의 통과시간이 각각 $3.92{\pm}7.72,\;3.27{\pm}6.37,\;3.41{\pm}5.57$시간 이었다. 단순 15분 유침후 대장 통과시간의 측정은 전대장 통과시간이 $10.48{\pm}12.35$시간, 우측 및 좌측 대장과 직결장의 대장통과 시간이 각각 $3.72{\pm}7.52,\;3.37{\pm}6.76,\;3.39{\pm}5.84$ 시간으로 유의하지 않았다(P>0.05) 전침 자극후 대장 통과시간의 측정은 전대장 통과시간이 $10.30{\pm}13.21$, 우측 및 좌측 대장과 직결장의 통과 시간이 각각 $3.92{\pm}8.02,\;3.07{\pm}5.41,\;3.31{\pm}5.49$ 시간으로 좌측 대장 통과시간이 유의한(P<0.05) 단축 소견을 보였고 우측, 직결장의 통과시간은 유의하지 않았다(P>0.05). 결론: 본 연구의 결과로서 좌측 대장의 통과시간이 천추와 상거허에 전침 자극시 유의하게 단축되는 것을 확인 할 수 있었다. 이것은 전침이 신경계나 체액성 작용에 의해서 신경의 흥분성을 증가시켜 좌측 대장에서 직결장쪽으로 대장 내용물의 이동을 촉진하는 것으로 생각 할 수 있다. 그러나 단순 유침에서는 침자극전 대장 통과시간과 차이를 보이지 않음으로서 모든 침자극이 정상인의 대장운동이 변화를 일으키지는 않는 것으로 생각되었으며 더욱이 전침자극후 좌측 대장외에 우측 대장, 직결장은 단순 유침과 전침자극에 모두 변화가 없었고 전대장 통과 시간의 변화도 유의성이 없어 천추와 상거허의 침자극은 정상인의 대장운동에 영향을 주지는 않을 것으로 사려되었다.

Background/Aims Irritable bowel syndrome (IBS) is a common disease characterized by intestinal dysmotility, the mechanism of which remains elusive. We aim to determine whether the high-affinity choline transporter 1 (CHT1), a determinant of cholinergic signaling capacity, modulates intestinal motility associated with stress-induced IBS. Methods A rat IBS model was established using chronic water avoidance stress (WAS). Colonic pathological alterations were evaluated histologically and intestinal motility was assessed by intestinal transit time and fecal water content (FWC). Visceral sensitivity was determined by visceromotor response to colorectal distension. RT-PCR, western blotting, and immunostaining were performed to identify colonic CHT1 expression. Contractility of colonic muscle strips was measured using isometric transducers. enzyme-linked immunosorbent assay was used to measure acetylcholine (ACh). We examined the effects of MKC-231, a choline uptake enhancer, on colonic motility. Results After 10 days of WAS, intestinal transit time was decreased and fecal water content increased. Visceromotor response magnitude in WAS rats in response to colorectal distension was significantly enhanced. Protein and mRNA CHT1 levels in the colon were markedly elevated after WAS. The density of CHT1-positive intramuscular interstitial cells of Cajal and myenteric plexus neurons in WAS rats was higher than in controls. Ammonium pyrrolidine dithiocarbamate partly reversed CHT1 upregulation and alleviated colonic hypermotility in WAS rats. Pharmacological enhancement of CHT1 activity by MKC-231 enhanced colonic motility in control rats via upregulation of CHT1 and elevation of ACh production. Conclusion Upregulation of CHT1 in intramuscular interstitial cells of Cajal and myenteric plexus neurons is implicated in chronic stress-induced colonic hypermotility by modulation of ACh synthesis via nuclear factor-kappa B signaling.

This study was examined the effects of Daesenggi-Tang on intestinal mucosa and gastrointestinal transit time and plasma lipids in rats. Adult male rats were fed four weeks on diets containing no addition(basal diet group), 5% cellulose(cellulose group) and Daesenggi-Tang group(Daesenggi-Tang group). The results were as follows; 1. The gastrointestinal transit times was significantly decreased in Daesenggi-Tang administered group compare to basal diet and cellulose groups. Carmine red mixed with Daesenggi-Tang, as a marker, was administered through a gastric tube for stomach or intracecally by a chronically implanted catheter for colon transit. Small intestinal transit and large intestinal transit time were significantly decreased in Daesenggi-Tang administered group compare to basal diet. 3. The height of jejunal villi was developed in Daesenggi-Tang administered group compare to basal diet. The thickness of mucosa and muscle layer of colonic mucosa were significantly developed in Daesenggi-Tang administered group compare to basal diet group. 4. The numerical change of goblet cell in colonic mucosa was increased acid mucin stained alcian blue in Daesenggi-Tang administered group compare to basal diet and cellulose group. 6. HDL-cholesterol of plasma lipid was increased in Daesenggi-Tang administered group compare to basal diet and cellulose groups. Theses results suggests that Daesenggi-Tang may be used in prevention and treatment of constipation resulting in increase of fecal weight, decrease of gastrointestinal transit time, development of intestinal villi, intensify of stainability of acid mucin in colon.

2 week study was conducted to investigate the effects of Interferential Current(IC) and Kaltenborn-Evjenth Orthopedic Manual Therapy(KEOMT) on functional constipation. Interventions were applied to spinal segments between $T_9-L_2$ which provides innervations to the gastrointestinal tract. Subjects(n=24) were randomly allocated to two treatment groups: the IC group or the KEOMT group. Results for the IC therapy demonstrated significant decrease with the colonic transit time(CTT) as well as scores on the constipation assessment scale(CAS). The frequency of defecations per week had increased significantly(p<0.05). The KEOMT displayed decreased CTT in the left colon region. The scores on the CAS were reduced and frequency of defecations per week had increased significantly (p<0.05). This study not only showed that both modes of therapy improved symptoms of constipation, but also optimized gastrointesti. nal content movement, eventuating in a more normalized CTT. In conclusion, both the IC therapy and the Kaltenborn-Evjenth Orthopedic Manual Therapy have shown to be effective interventions for improving functional constipation.

대장통과시간은 소화기관 질환의 병태생리에 따른 유형분류와 치료계획을 설정하는데 매우 중요한 역할을 수행한다. 사람에게는 만성변비환자나 장운동에 문제가 있는 환자를 분류하기도 한다. 본 연구는 국내에서 개발된 비투과 표지자 Kolomark를 이용한 개에서 대장의 통과시간을 측정하여 정상범위에 대한 기준을 제시하고자 한다. 건강한 Beagle 11마리(암컷 10마리, 수컷 1마리)를 대상으로 콜로마크를 이용하여 2, 4, 8, 12, 24, 48시간마다 대장에 대한 잔류 개수와 통과 개수를 측정하였다. 대장에서 시간에 따른 콜로마크의 잔류량은 유의하였다. 콜로마크는 투여 후 4시간 후에 대장에 나타나기 시작하였고 8시간 후부터 잔류량의 유의한 차이가 확인되었다. 12시간 경과 후 대장내 콜로마크가 평균적으로 가장 많이 관찰되었다. 투여 후 24시간 후에는 약간의 잔류량이 확인 되었지만 48시간이 지난 후에는 대장 밖으로 모두 배출되었다. 콜로마크를 섭취후 배출까지 평균배출시간은 28.36시간이었다. 이번 연구를 통하여 콜로마크를 통한 개에서 대장통과시간의 정상 값을 확립하였으며 이러한 결과를 바탕으로 향후 변비환자의 치료 및 생리학적 검사를 보다 적극적으로 이용하는데 기초자료가 되리라 판단된다.

In the present study, we examined whether four grains including adlay (AD), buckwheat (BW), glutinous barley (GB), and white rice (WR) affect the duration of food residence in the gastrointestinal tract and hepatic enzyme activities in rats fed different combinations of the grains. The rats were raised for 4 weeks on a high fat diet based on the American Institute of Nutrition-93 (AIN-93G) diets containing 1% cholesterol and 20% dietary lipids. Forty male rats were divided into four groups and raised for 4 weeks with a diet containing one of the grains. Corresponding to the dietary fiber contents of the experimental grains, gut transit time was shortest in the rats fed GB and increased in the order of BW, AD, and WR. In addition, the accumulated shortest transit time occurred in the GB group. Gut transit time affected weight gain and major organ weight, as it was closely related to the absorption of nutrients. The level of thiobarbituric acid reactive substance (TBARS) in liver was higher in rats fed WR, AD, BW, and GB, indicating that the other grains decreased oxidative stress in vivo more than WR. Glutathione, glutathione peroxidase, and glutathione S-transferase levels in the AD, BW, and GB groups were significantly higher than those in the WR group. In conclusion, reduced colonic transit time has been implicated in reducing the incidence of colon cancer, as evidenced by populations consuming diets rich in fiber. Whole grains such as AD, BW, and GB may contribute to a significant supply of antioxidants to prevent oxidative stress if they are consumed in large amounts.

The effects of indigestible dextrin on serum lipid and glucose concentrations, large intestinal functions, feces states, and gastrointestinal transit time were studied with 90 male Sprague-Dawley rats. Diets contained 0.5% cellulose(0.5CL control), 10% cellulose(10CL), and 10% indigestible dextrin I (10ID-I), respectively and were fed to the rats for 3 weeks. Serum cholesterol and LDL-cholesterol concentrations were lower in rats fed the 10ID-I diet. Serum triglyceride concentration was lower in rats fed the 10CL diet. Cecal content and cecum weight significantly increased in the rats fed the 10ID- I diet. Cecal pH of the rats fed the 10ID-I diet was lower than that of the rats fed the 0.5CL diet. Changes of fecal output were not observed in case of 0.5CL and 10ID-I diets but a significant increase was observed in the case of 10CL. Gastrointestinal transit time of 10ID-I was the longest among the three diets. These results demonstrate that indigestible dextrin delivered to the cecum was not digested and increased the cecal mass. Indigestible dextrin improves colonic health of rats by inducing low pH of the cecum. (Korean J Nutrition 31(6) 991-998, 1998)
