Current scintigraphic tests of gastrointestinal motor function provides relevant pathophysiologic information, but their clinical utility is controversial. Many scintigraphic methods are developed to investigate gastrointestinal motility from oral cavity to colon. These are esophageal transit scintigraphy, oropharyngeal transit study, gastric emptying test, small bowel transit time measurement, colon transit study and gastroesopahgeal reflux scintigraphy. Scintigraphy of gastrointestinal tract is the most physiologic and noninvasive method to evaluate gastrointestinal motility disorders. Stomach emptying test is regarded as a gold standard in motility study. Gastrointestinal transit scintigraphy also has a certain role in assessment of drug effect to GI motility and changes alter therapy of motility disorders. Scintigraphy provides noninvasive and quantitative assessment of physiological transit throughout the gastrointestinal tract, and it is extremely useful for diagnosing gastrointestinal motor dysfunction. This article reviews the current procedures, indications, significance and guidelines for gastrointestinal motility measurements by scintigraphy.

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. The height of jejunal villi was developed in Chilsun-Whan administrated group compare to basal diet The thickness of mucosa and muscle layer of colonic mucosa were significantly developed in Chilsun-Whan administrated group compare to basal diet group. 5. The change of goblet cell in colonic mucosa was increased acid mucin stained alcian blue in Chilsun-Whan administrated group compare to basal diet and cellulose group. 6. HDL-cholesterol of plasma lipid was increased in Chilsun-Whan administrated group compare to basal diet and cellulose groups. Theses results suggests that Chilsun-Whan 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.

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)

The effects of ethanol extract from radish seeds on gastrointestinal function in rats were investigated. Rats were divided into 2 groups of 8 rats each, the basal group and the radish seed ethanol extract group. The radish seed ethanol extract group had a significantly decreased gastrointestinal transit time, but a significantly increased fecal weight compared with the basal group. The radish seed ethanol extract group also had significantly higher duodenal villus height and greater colonic mucosal thickness than the basal group. The radish seed ethanol extract group had a greater proliferation of 5-bromo-2-deoxy-uridine (BrdU) immunoreactive cells in the gastric mucosa as well as in the mucosa and submucosa of the small and large intestine than did the basal group. Thus, radish seed ethanol extract may be useful in preventing constipation based on the observation of an increase in fecal weight, a decrease in gastrointestinal transit time, and positive changes in the intestinal mucosa.

The effect of propionylpromazine, acepromazine maleate, ketamine HCI, xylazine HCI, and pentobarbital sodium as chemical restraint drugs on the transit time of barium sulfate through the stomach and duodenum in 24 healthy cats was investigated. In the present study, propionylpromazine, acepromazine maleate, and ketamine HCI did not reveal significant effect on the gastroduodenal transit time, but xylazine HCI and pentobarbital sodium pro-longed the gastroduodenal transit time markedly compared with control group. Therefore it is concluded that propionylpromazine, acepromazine maleate, and ketamine HCI could be selected for upper gastrointestinal radiographs. but xylazine HCI and pentobarbital sodium should be avoided.

This study was performed to investigate the effect of promoting gastrointestinal function and inhibiting of decreasing body temperature of ginger extract(Zingiber officinale) in rats. In order to elucidate the gastrointestinal function and inhibiting effect of body temperature of native ginger and improved ginger, water extracts of ginger were orally administrated into rats. The results are as follows: The gastrointestinal transit time was significantly decreased in native ginger(7.66hrs) and improved ginger(7.72hrs) extract administrated groups compare to control group(8.44hrs). The mean red faecal weight was increased in native ginger(30.6%) and improved ginger(31.1%) extract administrated groups compare to control group(24.9%) for 24hrs. Inhibiting effect of decreasing body temperature induced by serotonin was increased in native ginger($1.116^{\circ}C$) and improved ginger($1.416^{\circ}C$) extract administrated groups compare to positive control group($0.384^{\circ}C$) during 40 minutes. Gastrin and CGRP immunoreactive density was more strongly expressed in native ginger and improved ginger extract administrated groups compare to control group. Serotonin immunoreactive density was more weakly expressed in native ginger and improved ginger extract administrated groups compare to control group. These results suggest that ginger extracts may enhance physiological activity such as gastrointestinal motility, protection of mucosa and gastric acid secretion in gastrointestinal tracts, and inhibits decreasing body temperature

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.

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 object of this study is to measure the transit time and passage rate of capsule endoscopy (CE) in the gastrointestinal tract in medium sized beagle dogs ($7{\sim}13\;kg$). Animals were divided into four groups: only capsule (group 1, n=10), capsule+water (group 2, n=10), mettoclopramide+capsule (group 3, n=10), metoclopramide +capsule+water (group 4, n=10). The capsule transit times through the stomach and small bowel were evaluated by radiography findings. Gastric transit time (GTT), small intestinal transit time (SITT) and complete passage rate were measured in four groups. GTT's for each group were as follows; $45{\pm}20\;min$ (group 1), $117{\pm}35\;min$ (group 2), $150{\pm}40\;min$ (group 3), and $154{\pm}65\;min$ (group 4), while SITT's were $75{\pm}20\;min$ (group 1), $195{\pm}55\;min$ (group 2), $70{\pm}15\;min$ (group 3), and $76{\pm}15\;min$ (group 4). The complete passage rates were 20% (group 1), 40% (group 2), 20% (group 3), 50% (group 4). In all groups, if CE could pass through the pylorus, it passed all small intestinal tracts within 8 hours (battery life). Administration of water helped CE to pass pylori, except in case of metoclopramide administration. These results indicate that CE could be an useful tool for examining gastrointestinal diseases in the veterinary medicine.
