  • 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.

  • The genus Aerva is distributed is temperate and stropical Asia and Africa. Aerva species, Aerva lanata and Aerva javanica have been used for antidiarrhoeal activity in Indian traditional medicine. A.lanata and A.javanica were screened separately for their. anti-diarrhoeal activity and their action on intestinal transit on their vacuum dried ethanolic and aqueous extracts at the dose of 800 mg/kg by standard methods. All the extracts showed significant antidairrhoeal activity and significantly reduced intestinal transit in charcoal meal test. The results illustrate that the ethanolic and aqueous extracts of A.lanata and the ethanolic and aqueous extracts of A.javanica have significant antidiarrhoeal activity and the activity may be attributed to its effect on intestinal transit. The present study supports the claim of Aerva lanata and Aerva javanica as antidiarrhoeal drugs in the Indian system of medicine.

  • Objectives: To clarify the effects of Jungri-tang Gamibang on accelerating small intestinal movement induced by the stimulation of cholinergic neurotransmission. Methods: 500, 250 and 125mg Jungri-Tang Gamibang or 20mg domperidone were dissolved or suspended in distilled water and orally pretreated on the carbachol-accelerated small intestinal transit mice once a day for 7 days at a volume of 10ml/kg (of body weight) using a Zonde needle attached to 1 ml syringes containing test drugs. Result: Significantly (p<0.01) increase of % regions of activated charcoal transit in the small intestine was detected in carbachol control compared to that of intact control. However, significant (p<0.01) decreases of % regions of activated charcoal transit were dose-dependently observed in all Jungri-Tang Gamibang extracts or domperidone-pretreated groups. Conclusions: it was concluded that Jungri-tang Gamibang enhancement in the normal intestinal motility and normalization in the accelerated intestinal motility might interfere with a variety of muscarinic, adrenergic and histaminic receptor activities or with the mobilization of calcium ions required for smooth muscle contraction non-specifically.

  • This study was performed to investigate the role of glutamate neurotransmitter system on gastrointestinal motility in a middle cerebral artery occlusion (MCAO) model of rats. The right middle cerebral artery was occluded by surgical operation, and intestinal transit and geometric center as a parameter of gastrointestinal motility and expression of c-Fos protein in the insular cortex and cingulate cortex were measured at 2 and 12 h after MCAO. Intestinal transit was $66.3{\pm}7.5%$ and $62.3{\pm}5.7%$ 2 and 12 h after sham operation, respectively, and MCAO significantly decreased intestinal transit to $39.0{\pm}3.5%$ and $47.0{\pm}5.1%$ at 2 and 12 h after the occlusion, respectively (p<0.01). The geometric center was $5.6{\pm}0.4$ and $5.2{\pm}0.9$ at 2 and 12 h after sham operation, respectively, and MCAO significantly decreased geometric center to $2.9{\pm}0.8$ and $3.0{\pm}0.3$ at 2 and 12 h after the occlusion, respectively (p<0.01). In control animals, injection of atropine decreased intestinal transit to $35.9{\pm}5.2%$, and injection of glutamate NMDA receptor antagonist, MK-801, decreased intestinal transit to $28.8{\pm}9.5%$. Pretreatment with MK-801, a glutamate NMDA receptor antagonist, in the MCAO group decreased intestinal transit to $11.8{\pm}3.2%$, which was significantly decreased compared to MCAO group (p<0.01). MCAO markedly increased the expression of c-Fos protein in the insular cortex and cingulate cortex ipsilateral to the occlusion 2 h after MCAO, and pretreatment with MK-801 produced marked reduction of c-Fos protein expression compared to MCAO group (p<0.01). These results suggest that modulation of gastrointestinal motility after MCAO might be partially mediated through a glutamate NMDA receptor system.

  • In Vivo and In vitro antispasmodic effects of Jun-Si-Baek-Chul-San, a Traditional Korean Polyherbal Medicineconsisted of 7 types of herbs were observed in the present study. To clarify the effects of Jun-Si-Baek-Chul-San, on accelerating small intestinal movement induced by the stimulation of cholinergic neurotransmission, we evaluated the effects of Jun-Si-Baek-Chul-San on In vivo carbachol (an acetylcholinergic agent)-accelerated mice small intestinal transit and on In vitro contractions induced by low-frequency electrostimulation, KCl, histamine or acetylcholine using isolated guinea pig ileum. To induce the acceleration of mice small intestinal transit, Carbachol 1 mg/kg was once subcutaneously dosed 15min before last administration of the test drugs. In the present study, Jun-Si-Baek-Chul-San 500, 250 and 125 mg/kg or domperidone 20 mg/kg were orally pretreated on the carbachol-accelerated mice small intestinal transit once a day for 7 days and the small intestinal transit rateof activated charcoal powder were monitored. In vitro assays, Jun-Si-Baek-Chul-San1, 0.1, 0.01 and 0.001 mg/ml or domperidone $2{\times}10^{-5}M$ were treated 10min before ileal contraction was induced by filed stimulation, acetylcholine, KCl and histamine, and the % changes of contractions were observed compared to the treatment of inducer alone. In spontaneous contraction, the % changes of contractions were observed compared to treatment of vehicle alone at 10min after Jun-Si-Baek-Chul-San or domperidone treatment. The efficacy of Jun-Si-Baek-Chul-San was compared to those of domperidone. High concentration, 1 mg/ml of Jun-Si-Baek-Chul-San was found to decrease the spontaneous contraction of the isolated guinea-pig ileum. In addition, Jun-Si-Baek-Chul-San decrease contractions induced by electrostimulation, acetylcholine, histamine and KCl in the isolated guinea-pig ileum. In addition, Jun-Si-Baek-Chul-San effectively inhibited the accelerated small intestinal movement induced by carbachol stimulation of cholinergic neurotransmission in In vivo. Based on the results, although the exact molecular or action mechanism and which herbs or compound in Jun-Si-Baek-Chul-San are responsible for actions, it was concluded that Jun-Si-Baek-Chul-San normalization in the accelerated intestinal motility might be interfere with a variety of muscarinic, adrenergic and histaminic receptor activities or with the mobilization of calcium ions required for smooth muscle contraction non-specificly. Therefore, it is expected that Jun-Si-Baek-Chul-San will be promising as a prescription of clinical treatment of digestive tract disorders such as accelerated the motility of intestine, diarrhea or intestinal painful contractions.

  • Small intestinal transit (SIT) has often been regarded as an index of pathophysiological state of postoperative ileus (PI) in rats. The reliability of SIT as an index of PI was examined in the present study. PI was induced via abdominal surgery (i.e., laparotomy with evisceration and manipulation) in rats. For one group of PI-induced rats, SIT of a charcoal test meal was measured. When necessary, the physical state (i.e., severity and site of distension) of the gastrointestinal (GI) tract in each rat was visually examined. For another group of PI-induced rats, abdominal X-ray radiographs were obtained after introducing the barium sulfate suspension. The abdomen was then opened and the physical state of the GI tract was visually examined. The SIT was decreased in most of the PI-induced rats, and the GI distension was observed, with substantial intersubject variations, in all of the PI-induced rats. However, no linear relationship was evident between the SIT and the severity of GI distension (e.g., at 20 h after PI induction). Instead, the severity and site of GI distension could be monitored by the X-ray radiology. Therefore, the use of SIT as an index of PI should be substantially limited.

  • 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)

  • Objectives: The purpose of the present study was to investigate the antidiarrheal effects of Anjang-san in mice and rats. Methods: We measured the content of condensed tannin in Anjang-san extract, and observed the effects of Anjang-san on the small intestinal and colonic transport of mice, as well as on mice models of diarrhea induced by castor oil and $MgSO_4$, and on rat models of castor oil-induced enteropooling. Results: Anjang-san showed significant inhibitory effects on abnormally increased small intestinal transit induced by pyridostigmine and neostigmine, and inhibitory effects on large intestinal transit. Anjang-san also exhibited antidiarrheal effects on diarrhea induced by $MgSO_4$, and inhibitory effects on castor oil-induced enteropooling. Anjang-san also improved castor oil-induced diarrhea based on simple numbers without statistical significance. Conclusion: These results demonstrate that Anjang-san has significant antidiarrheal properties and attests to its possible utility in functional diarrheas, irritable bowel syndrome and other gastrointestinal disorders based upon further studies.
