설탕의 40%를 프락토올리고당이나 이소말토올리고당으로 대치하여 구운 스폰지 케이크를 2주간 섭취하게 하여 여대생의 변비개선에 대한 효과를 살펴보았다. 두 올리고당 모두 섭취 후 배변 횟수와 변의 경도를 유의적으로 개선시켰다. 프락토올리고당을 첨가한 스폰지 케이크를 섭취한 군에서는 배변시간이 섭취 1주 후부터 유의적으로 감소하였으며, 이소말토올리고당을 첨가한 스폰지 케이크를 섭취한 군에서는 변의 모양, 변색, 배변 시 노력과 배변 후 상쾌함 등이 섭취 전보다 섭취 후에 유의적으로 개선되었다. 섭취 중에 나타난 소화장애 현상으로는 설사, 복통, 메스꺼움, 더부룩함, 방귀, 식욕 감소, 체중감소, 복부 팽만감 등이 나타났고, 프락토올리고당을 첨가한 스폰지 케이크 섭취 군에서는 이들 장애현상 중 복부 팽만감이나, 방귀, 메스꺼움 현상이 섭취 후 1~2시간 안에 나타나기 시작하여, 실험 기간 내내 지속되었다. 반면 이소말토올리고당을 첨가한 스폰지 케이크를 섭취한 군에서는 2~3일 정도 소화장애 현상이 나타났으나, 그 후에는 섭취 후에 장애 현상이 없어졌다. 섭취종료 일주일 후에는 프락토올리고당에 의한 소화장애 현상은 곧 사라졌으나, 대부분의 피검자들은 섭취 전에 나타난 변비현상이 다시 나타났다. 배변상황의 개선여부와 소화장애 현상을 종합적으로 판단하였을 때, 두 올리고당 모두 인체의 장기능 개선에는 효과가 있었으나, 비교적 안전성이 좋은 이소말토올리고당을 첨가한 스폰지 케이크 섭취가 변비 치료에는 더 긍정적으로 나타났다.

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.

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%).

목적: 장막침윤이 없는 위암환자에 있어서 수술 후 서로 다른 보조화학요법이 장기 생존에 미치는 영향에 대해 평가하고자 하였다. 대상 및 방법: 1996년 10월부터 1998년 3월까지 만 15개월간 서울 아산병원 외과에서 근치적 위 절제를 시행한 환자 중, 장막침윤이 없는 317명의 환자를 대상으로 하였다. 이중 수술 후 병기가 IA인 131예, 장막침윤이 있는 34예, 그리고 치료를 거부한 17예를 제외한 135명(1군: 5-FU+cisplatin 정주, 2군: mitomycin C정주+경구용5-FU, 3군: 경구용 5-FU)의 의무기록 분석과 전화추적을 실시하여 재발양상, 생존율, 및 위암관련 사망률을 각 군별로 분석하였다. 결과: 121명에서 추적이 가능해 $89.6\%$의 생존율을 나타냈다. 재발은 1군 4명, 2군 7명, 그리고 3군 6명 이었으며, 세 군의 전체생존율은 1군 $89\%$, 2군 $84\%$, 그리고 3군은 $82\%$이고, 위암관련 사망환자만을 고려한 질병특이 생존율은 1군 $92\%$, 2군 $86\%$, 그리고 3군은 $88\%$로 나타나 이들 세 군간에 전체생존율 및 질병특이 생존율은 차이를 보이지 않았다(전체생존율: P=0.6875, 질병특이 생존율: P=0.7120). 결론: 장막침윤이 없는 위암 환자에서, 치료효과를 향상 시키기 위해 보조요법을 시행할 경우 경구용 항암제를 이용한 방법이면 충분하다고 판단하였다. 그러나 이를 입증하기 위해서는 보조요법을 시행치 않는 대조군을 포함한 대단위 무작위 연구가 필수적일 것이다.

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.
