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.

Purpose: The Oral-anal Transit Test (OTT) is a simple method of obtaining information about colonic transit. We aim to assess the correlation of OTT with the neuromuscular integrity of the colon determined by colonic manometry (CM). Methods: All patients who had OTT followed by CM were evaluated. Less than 6 of 24 markers remaining on OTT was considered normal. CM was performed per previously published guidelines. A normal CM was defined as at least one High Amplitude Propagating Contraction progressing from the most proximal sensor through the sigmoid colon. Results: A total of 34 patients underwent both OTT and CM (44% male, age 4-18 years, mean 11.5 years, 97% functional constipation +/- soiling, Hirschsprung's Disease). Of normal and abnormal OTT patients, 85.7% (6/7) and 18.5% (5/27) respectively had normal CM. When all markers progressed to at least the sigmoid colon, this was 100% predictive against colonic inertia. Greater than 50% of patients with manometric isolated sigmoid dysfunction had markers proximal to the recto-sigmoid. Conclusion: OTT and CM are both valuable studies that assess different aspects of colonic function. OTT can be used as a screening test to rule out colonic inertia. However, the most proximal extent of remaining markers does not predict the anatomical extent of the manometric abnormality, particularly in isolated sigmoid dysfunction.

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.

Functional constipation is regarded as a long-standing symptomatic manifestation of abnormal defecation expressed by either a reduced frequency of bowel movements and /or an altered act of evacuation. Patients with constipation can be treated with laxatives, diets and regular habits. Thorough evaluation of functional constipation is considered in those in whom conservative treatment with dietary advice and use of laxatives fails. Patients with normal colonic transit and normal anorectal function may only need reassurance, education and dietary advice with fiber supplementation. For constipated patients in whom such treatment modalities fail, laxatives including bulk-forming and osmotic agents may be used Although most laxatives, if used intermittently, are relatively safe, they must be chosen bearing in mind possible side effects, patient compliance and their action mechanisms. A subgroup of patients with slow transit through the colon ay be unresponsive to conventional laxatives, and, in these subjects, a trial with enteroprokinetics and sometimes stimulant laxatives should be attempted. This article presents our view of the assessment and pharmacologic treatment of functional constipation.

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.

Constipation is a common clinical problem that comprises of symptoms that include excessive straining, hard feces, feeling of incomplete evacuation and infrequent defecation. Although many conditions, such as metabolic problems, fiber deficiency, anorectal problem, an drug, can cause constipation. This study was examined the effects of Chilsun-Whan on intestinal mucosa and gastrointestinal transit time and plasma lipids in rats. Adult male rats were fed for weeks on diets containing no addition(basal diet group), 5% cellulose(cellulose group) and 2.5% . Chilsun-Whan group(Chilsun-Whan group). The results were as follows; 1. The fecal weght was significantly increased 2 times in Chilsun-Whan administrated group compare to basal diet group. 2. The gastrointestinal transit times was significantly decreased in Chilsun-Whan administrated group compare to basal diet. 3. Carmine red mixed with Chilsun-Whan, 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 Chilsun-Whan administrated group compare to basal diet. 4.
