The aim of this study was to evaluate the effects of 40% sucrose replacement with oligosaccharides (fructo- orisomalto-) in sponge cakes. The 18 female college students were divided into two groups; fructooligosaccharide sponge cake group (FOS) and isomaltooligosaccharide sponge cake group (IMOS). In each group, the subjects received 50 g/d of sponge cake which contained about 8 g oligosaccharides for 2 weeks. The results were as follows: (1) Frequency of stool evacuation tended to increase after 1 week and significantly increased after 2 weeks in both groups. (2) Shape and color of stool did not change in FOS group but the IMOS group showed significant improvement. (3) The stool amounts per defecation were not significantly different in both groups. (4) The time of defecation decreased 50% after 1 week in FOS group and tended to decrease gradually in IMOS group. (5) Consistency of stool was significantly decreased after 1 week in both groups and continuously decreased until 2 weeks. (6) Effort for evacuation and comfort feeling after evacuation were significantly improved only in IMOS group after 2 weeks. (7) Gastrointestinal complaints concerning diarrhea, abdominal pains, nausea, flatulence, loss of appetite and weight and bloating were apparent. The symptoms such as abdominal pains, flatulence, and bloating in FOS group lasted for 2 weeks. However, the complaints appeared only during two or three days in IMOS group. In conclusion, our results suggest that isomaltooligosaccharide was more effective than fructooligosaccharide for preventing constipation because isomaltooligosaccharide worked safely in gastrointestinal lumen.

Two experiments were conducted to compare the effects of feeding organic acids and antibiotic growth promoters in weaned pigs. In Exp. 1, 96 nursery pigs (Large White$\times$Landrace; initial weight $7.80{\pm}0.07kg$) were randomly allotted into one of four dietary treatments. Pigs in treatment 1 were fed a complex starter diet. Treatments 2 to 4 were the same as treatment 1 but supplemented with antibiotics (200 ppm chlortetracycline plus 60 ppm Lincospectin), 0.5% potassium diformate or 0.5% dry organic acid blend ACTIVATE Starter DA (ASD). During the 4-week post-weaning period, pigs fed ASD or antibiotics had better gain (p = 0.03) and feed efficiency (p = 0.04) than pigs fed the control diet. On d 14 post-weaning, pigs fed the control diet had the lowest fecal lactobacilli count among all dietary treatments (p = 0.02), whereas pigs fed ASD or antibiotics had a trend for lower fecal E. coli count compared to the control pigs (p = 0.08). Serum insulin-like growth factor-1 (IGF-1) of pigs fed ASD did not differ from pigs fed the control diet (p>0.05) at d 14 after weaning. In Exp. 2, 24 weaned pigs (Large White$\times$Long White; initial weight $5.94{\pm}0.33kg$) were allotted into four groups and housed individually. Pigs were fed a control diet or diets supplemented with antibiotics (100 ppm colistin sulfate, 50 ppm Kitasamycin plus 60 ppm Olaquindox), 0.5% or 1% ASD. All pigs were orally challenged with E. coli $K88^+$ on d 5. During d 5 to 14 after challenge, pigs fed antibiotics, 0.5% or 1% ASD had better gain (p = 0.01) and feed efficiency (p = 0.03) than pigs fed the control diet. On d 14, compared to the control pigs, pigs fed 0.5% ASD had higher lactobacilli in the duodenum and pigs fed 1% ASD and antibiotics had a trend for higher lactobacilli in the ileum (p = 0.08). Pigs fed antibiotics, 0.5% or 1% ASD diets tended to have decreased ileal E. coli count compared to those fed the control diet (p = 0.08). Serum interleukin-6 and cortisol and digesta pH values were not affected by treatment or time. These results indicate that feeding ASD can improve the growth performance of weaning pigs, mainly via modulating intestinal microflora populations without affecting gastrointestinal pH or immune indices.

Purpose: To investigate the clinicopathlogical characteristics and the surgical methods for gastric submucosal tumors in Korea, the Information Committee of the Korean Gastric Cancer Association performed a nationwide survey. Materials and Methods: Data on 878 patients who underwent resection from 2005 to 2006 were collected from medical records obtained from 47 institutes. Diagnosis, demographics, symptoms, tumor factors (location, size, degree of malignancy) and operative factors (surgicalmethod and approach, mortality) were analyzed. Results: Gastrointestinal stromal tumors (GISTs) were the most common cancers (n=586, 66.8%), followed by leiomyomas (n=97, 11.1%), schwannomas (n=70, 8.0%), ectopic pancreas (n=67, 7.8%) and carcinoids (n=16, 1.8%). The mean age of patients was 56.0 years and the male to female ratio was 1:1.18. Only 40.9% of the patients had symptoms at the time of diagnosis, such as abdominal pain, dyspepsia and bleeding. Gastric submucosal tumors were most frequently located in the upper third of the stomach and 55.4% of the GISTs (n=319) and 84.5% of the leiomyomas (n=84.5%) were located in the upper third of the stomach. Wedge resection (n=726, 82.8%) was the most common operative method, and laparoscopic surgery was performed in 388 patients (44.2%). Only one patient (0.1%) died within 30 days of surgery. A total of 115 patients withGISTs (21.1%, 115/544) had a high risk of malignancy and 41 patients (8.3%, 45/495) received adjuvant imatinib mesylate therapy. Conclusion: The survey showed that about two-thirds of the patients with a gastric submuscoal tumor (SMT) had a GIST, and about one-half of the patients underwent laparoscopic resection. These data presented in the nationwide survey could be used as a fundamental resource for gastric submucosal tumors in Korea.

In order to elucidate the influence of intestinal and hepatic first-pass effect on the pharmacokinetics of triflusal, the biotransformation of triflusal in the gastrointestinal tract and liver was designed. Moreover, we tried to establish an HPLC method applicable for bioassay and available to pharmacokinetics, not only with the simultaneous determination of triflusal and its active metabolite, 2-hydroxy-4-trifluoromethyl benzoic acid (HTB), but also with improving sensitivity. After the administration of triflusal (10 mg/kg) and HTB (10 mg/kg) into femoral vein, portal vein (only triflusal) and oral route (only triflusal), pharmacokinetic parameters were investigated from the plasma concentration-time profiles of triflusal and HTB in rats. An HPLC method was developed for the simultaneous determination of triflusal and HTB in rat plasma, urine and bile. The HPLC analysis was carried out using a C18 column and acetonitrile-methanol-water (25:10:65, v/v/v) as the mobile phase and UV detection at 234 nm. Furosemide was used as the internal standard. The calibration curves were linear over the concentration range $0.05-5.0\;{\mu}g/ml$ for triflusal and $0.2-200.0\;{\mu}g/ml$ for HTB with correlation coefficients greater than 0.999 and with intra-day or inter-day coefficients of variation not exceeding 10.0%. This assay procedure was applied to the study of metabolite pharmacokinetics of triflusal and HTB in rats. It was supposed that triflusal was almost metabolized in vivo because urinary and biliary excreted amounts of triflusal could be ignored as it was lower than 1.2% of the administered dose. According to the gastrointestinal and hepatic biotransformation pathways of triflusal, it was found that triflusal was hydrolyzed by about 5% in intestine and metabolized by about 53% in liver, and that the bioavailability of triflusal after oral administration of triflusal was 0.44, and also that the fraction of total elimination rate of triflusal which formed HTB in liver $(F_{mi},\;%)$ was about 98%. These results showed that triflusal was almost metabolized in liver, and the total elimination of triflusal in the body was dependent to the formation rate of HTB from triflusal in liver.

The purpose of this stady was to investigate division cells by in vivo bromodeoxyuridine(Brdur) immunohistochemistry for labeling the proliferative epithelial cells in the gastrointestinal tracts of rats. Rats were administrated intraperitonially by twice consecutive injections of 24 hr interval with Brdur(0.05mg/g BW/time) and then were sacrificied at 1 hour after last injection. The specimens were taken from the stomach, small intestine(ileum), and large intestine(colon). The well-oriented crypts and villi in the preparations were examined, The crypt columns and villi were devided into 10 segments from crypt base to surface of the lumen or to villis top. Labeling index(LI) was measured by counting the number of Brdur-positive cells against the total number of crypt column cells in the stomach and large intestine and also against the total numbers of crypt column and it's villi epiterial cells in the small intestine. 1. In the stomach, the LI in each part from segment 1 to segment 10 of the crypt column were 4.2%, 5.0%. 6.6%, 9.0%, 11.3%, 15.3%, 9.3%, 15.6%, 11.3%, 0%, respectively and it's mean LI were 8.7%. The Brdur-positive epithelial cells were predominantly located in the middle regions and middle-upper regions of the crypt columns. 2. In the small intestine, the LI in each part from segment 1 to segment 10 of were 62.4%, 50.9%, 27.8%, 22.5%, 18.6%, 12.1%, 7.5%, 4.3%, 2.5%, 1.4%, respectively and it's mean LI were 21.0%. The Brdur-positive epithelial cells were predominantly located in the lower regions of the crypt columns and tended to be less in the higher regions of the villi than that in the crypt column. 3. In the large intestine, the LI in each part from segment 1 to segment 10 of the crypt column were 19.4%, 29.9%, 34.1%, 41.6%, 41.2%, 32.4%, 25.4%, 15.4%, 10.8%, 1.2%, respectively and it's mean LI were 25.1%, The Brdur-positive epithelial cells were predominantly in the middle and middle-lower regions of the crypt columns. 4. The organs with higher LI were ordered as the large intestine(25.1%), small intestine(21.0%) and stomach(8.7%).

Purpose: We reported our preliminary result in 2001. At that time, the follow-up period was too short to evaluate the survival benefit of adjuvant chemotherapy in gastric cancer without serosal invasion. Therefore, we followed those patients for 66 months to determine the long-term effects of adjuvant chemotherapy. Materials and Methods: We analyzed the recurrence pattern, the survival rate, and the disease-specific survival of 135 patients by reviewing their medical records and calling the patients or their relatives. All enrolled patients were included in the intention-to-treat analysis of efficacy. Results: The follow-up rate was $89.6\%$ (121/135), and the median follow-up duration was 66 months. Among the 135 patients, 4 relapsed in group 1 (5-FU+cisplatin), 7 in group 2 (mitomycin C+oral 5-FU), and 6 in group 3 (oral 5-FU only). The overall survival rate was $89\%$ in group 1, $84\%$ in group 2, and $82\%$ in group 3. There were no differences in the overall survival rates and the disease-specific survival rates among the three groups. Conclusion: Oral chemotherapeutic agents have an acceptable effect for adjuvant chemotherapy compared with intravenous agent. However, a large-scale, prospective, randomized study, including a control group, is needed for an exact evaluation.

Behest's disease is manifested as ulcers present in oral cavity, on external genital organ, orbital area, and skin. This disease could also cause other symptoms by invading the cardiovascular system, respiratory system, gastrointestinal system, central nervous system, and urogenital system. It is very rare for Behcet's disease to be accompanied by carotid artery aneurysm and intestinal perforation. We report a patient with Behcet's disease, who is diagnosed with symptoms and pathological findings as haying carotid artery aneurysm and intestinal perforation at the same time. The patient underwent operation for the aneurysm and the intestinal perforation.

Migraine is a very common unilateral and throbbing headache, and a chronic relapsing and remitting disorder characterised by neurological, gastrointestinal, and autonomic changes. It has a high prevalence, often recurs at the time of being in full activity of life, and has a serious impact on patients personally and socially. So we need to develop a oriental medicine for migraine. I have treated two migraine patients using Zhuapiandutongbang (Zuopiantoutongfang) of Dongyibogam. The impression of first case is migraine with aura, and that of second case is probable migraine. We just give Zhuapiandutongbang (Zuopiantoutongfang)'s medicine to two patients, but don't apply acupucture and anything to treat. We reported that Zhuapiandutongbang (Zuopiantoutongfang) has a good effect on not only the improvement of symptoms but also the prevention of relapse.

Ketoprofen is one of the propionic acid class of nonsteroidal anti-inflammatory drug with analgesic and antipyretic effects. The most common side effects from ketoprofen after oral administration are gastrointestinal irritation, diarrhea, abdominal pain and retention of fluid. Ketoprofen was formulated as water-soluble gels to reduce these side effects. To increase the skin permeability of ketoprofen, microsphere containing ketoprofen was prepared with chitosan and ploy-$\varepsilon$-caprolactone. And then prepared microsphere was manufactured as an adhesive hydrogel with polyvinylpyrrolidone K-25, polyethylene glycol 4000, and various permeation enhancers. The flux and permeability of ketoprofen were evaluated. As the concentration of tween 80 and enhancers increased, the flux of ketroprofen was accelerated. Also the permeation rate was facilitated by enhancers, but did not affect the lag time. From these results, the adhesive hydrogel using microsphere could be a good delivery system for ketoprofen to improve the skin permeation.

DA-5018(N-(3-(3, 4-dimethylphenyl)propyl)-4-(2-aminoethoxy)-3-methoxyphenylacetamide) is a new capsaicin derivative under development as topical analgesic agent. The general pharmacological properties of DA-5018 on central nervous, cardiovascular, gastrointestinal and other organ systems were studied in experimental animals. DA-5018 cream (0.3%) had no effects on behavior, hexobarbital-induced sleeping time, body temperature, spontaneous activity, blood pressure, heart rate, intestinal charcoal propulsion, urine volume and electrolyte excretion even at a high dose of 2000 mg/kg in rats. In addition, DA-5Ol8 cream had little skin irritation compared to Zostrix-HP (capsaicin, 0.075%) cream in rabbits. In isolated guinea pig tissue studies, DA-5018 increased the contractility of trachea and ileum and also increased sinus rate of atrium in a range of 10^{-8}-10^{-5}$$ M, but its efficacy as a agonist was weak. These results suggest that DA-5018 cream might be used topically without serious side effects.
