각질형성세포의 배양법이 개발 후 피부 결손 부위의 치료에 인체 각질형성세포를 배양하여 얻어진 표피를 이식하거나 세포부유물을 도포하는 기존의 방법들은 trypsin 처리 과정을 거치면서 배양된 세포의 부착능력을 가진 단백질이 손상되어 성공적인 피부 재생이 불가능하다. 이 연구에서는 면역결핍 생쥐 모델에서 인간 피부 각질형성에포와 EGF-피브린 고분자 혼합물을 분사하여 피부의 전층 상처를 재생하였다. 조직학 검사와 면역화학검사를 통하여 각질형성세포와 EGF-피브린 고분자를 함께 분사한 경우 이식된 인간 표피세포에 의한 빠른 표피재생을 확인할 수 있었다. 이 피부 재생술은 기존의 배양된 인공피부 sheet의 이식을 이용한 피부재생법에 비해 여러 가지 장점을 가지고 있으므로, 앞으로 화상이나 피부궤양과 같은 피부결손의 효율적인 새로운 치료법으로 사용되어질 수 있을 것이다.

Propolis, a natural resinous compound collected from honey bees, contains many biochemical constituents(wax, flavonoids, phenolic compounds, etc.) and has been used in traditional medicines as early as 300 B.C. It was been demonstrated that ethanol, acetylsalicylic acid, ischemia reperfusion, non-steroidal antiin-flammatory drugs and stress induce gastric lesions by promoting the generation of reactive oxygen metabolites. Therefore, some drugs that are capable of scavenging or inhibiting the generation of reactive oxygen radicals might be expected to prevent the gastric mucosal injury. The aim of this study was 1) to examine the antiulcer effect of propolis, 2) to investigate the mechanism of action by determining gastric acid secretion, lipid per-oxidation, mucus content and proton pump ($H^+$/$K^+$-ATPase) activity on gastric mucus in varios experimental models, and finally, 3) to isolate and identify the pure compounds that exert antiulcer activity. Step 2-1 and 2-3 sub-sub fraction shoed a significant reduction of severity of gastirc damage at the dose of 25 mg/kg in various experimental models. We isolated 4 sub-sub-sub fractions by flash column chromatography of Step 2-1 sub-sub fraction and one sub-sub-sub fraction by recrystalization of Step 2-3 sub-sub fraction. The protective effects of propolis sub-sub-sub fraction manifested sifnificant effects in HCl-ethanol induced gastric erosion model and aspirin induced gastric ulcer model. These results showed that the gastric mucosal protective effect of propolis might result from the increase of mucus secretion, free radical scavenging effect as well as the reduction of acid secretion in accordance with the reduction of $H^+$/$K^+$-ATPase activitv. Three compounds were isolated and identified from sub-sub fraction of propolis which showed antiulcer effects. Subsequently, these compounds were identified as a flavonoid, namely, 2-acetoxy-5,7,-dihydroxy-flavanone, galangin and chrysin.

Background: The over-prescription of acid-suppressive therapy for the provision of stress ulcer prophylaxis (SUP) in hospitalized patients has been identified in a proceeding study. Objective: This study was conducted to evaluate clinicians' beliefs, knowledge and other factors that influence the over-prescribing of SUP in low-risk, non-intensive care unit (non-ICU) patients. Method: A cross-sectional survey consisting of multiple-choice queries and close-ended questions was distributed to healthcare personnel at a major teaching hospital in Korea. Results: More than half of total respondents reported that they would continue SUP following patients discharge from the ICU (77.8%, 43.5%, and 39.7% in the physician, pharmacist, and nurse groups, respectively). Over 55% of physicians would also initiate non-ICU patients on SUP upon hospital admission, and 42.6% of physicians would even continue prophylaxis post hospital discharge. The mean knowledge score regarding SUP indications and side effects was higher in pharmacists compared to physicians and nurses (12.44, 7.40, and 7.28, respectively; p<0.001). High-prescribing behavior was associated with a prescriber's belief that SUP is effective for preventing bleeding (odds ratio 7.40; 95% confidence interval 1.57 to 31.94; p=0.012). Low knowledge score and computerized order set also showed statistically significant association with the overutilization of SUP.

각질세포의 배양법이 개발 후 피부 결손 부위의 치료에 인체 각질세포를 배양하여 얻어진 표피를 이식하는 방법부터 세포부유물을 도포하는 방법들은 Trypsin 처리 과정을 거치면서배양된 세포의 부착능력을 가진 단백질이 손상되어 성공적인 피부 재생이 불가능하다. 본 실험에서는 이러한 효소처리의 단점을 보완하기 위해서 고분자 미립구에 세포를 효소처리 과정없이 동물실험을 한 결과 21일 후에는 대조군에 비해서 표피가 완벽하게 재생되었고 이식 후 세포의 부착면적을 늘리고 생착율을 높일 수 있었다. 이 연구에서 효소처리 없이 고분자 미립구에서 배양된 세포를 이용한 인공피부 재생이 효과적인 것을 보여주었다. 이러한 모델은 앞으로 화상이나 궤양으로 인한 피부 손실 부위 치료에 사용될 수 있을 것으로 생각된다.

Objectives: This study reports on the efficacy of using Korean medical treatment for suspected gastric ulcer. Methods: We treated a patient with suspected gastric ulcer using Korean medical treatments (herbal medicines, acupuncture, and herbal acupuncture therapy). We evaluated the results using a numerical rating scale (NRS) to measure abdominal pain. The degree of gastrointestinal symptoms was also evaluated using the Korean Gastrointestinal Symptom Rating Scale (KGSRS). The generic health status was evaluated using the European Quality of Life-5 Dimensions (EQ-5D) scale. Results: The NRS and EQ-5D scale scores were improved after the treatments. The change in the KGSRS scores showed that the patient's abdominal pain was relieved. Conclusions: The results of this case study suggest that Korean medicine therapies may be effective in the treatment of suspected gastric ulcer.

헤노흐-쇤라인 자반증(HSP)은 소아에서 가장 흔한 혈관염으로 피부 자반증, 관절염, 복통, 그리고 신염 등을 특징으로 한다. HSP 소아에서 물집을 동반하는 경우는 매우 드물다. 관절염을 동반한 HSP를 보인 9세 여아에서 경구용 스테로이드 치료를 시작했음에도 불구하고 피부 자반이 빠르게 출혈성 물집 병변으로 진행되었다. 치료 7일 후 몇몇 궤양성 병변은 경미한 흉터로 남았으나 관찰 6개월 후 흉터는 완전히 소멸되었다. 현미경적 혈뇨는 관찰 6개월간 지속되었으나 단백뇨는 관찰되지 않았다. HSP 소아에서 물집이 동반되었을 경우, 신장의 예후에는 직접적인 연관은 없었다. 임상적으로 HSP 진단기준을 만족한다면 HSP 진단을 위해 피부조직검사는 필요 없을 것으로 보이며, 더 많은 증례가 모이면 정확한 결론을 내릴 수 있을 것으로 사료된다. 관절염을 동반한 HSP 9세 여자 소아에서 경구용 스테로이드 치료를 시작했음에도 불구하고 피부 자반이 빠르게 출혈성 물집 병변으로 진행되는 HSP 증례를 경험하였기에 보고하는 바이다.

Objectives: This study was conducted to determine, by reviewing the literature, whether treatment of Helicobacter pylori infection in patients with non-ulcer dyspepsia affects symptoms. Methods: We retrieved the literature using MEDLINE search, with nonulcer dyspepsia and Hericobacter pylori and treatment as key words, which were reported from 1984 to 1998, and manual literature search. The criteria for inclusion was as follows; 1) The paper should have confirmed nonulcer dyspepsia as case definition. 2) The paper should have peformed a randomized, blind trial. 3) Confirmation of Helicobacter pylori eradication should be done 4 weeks after treatment. 4) studies with no information on measurement of symptoms after treatment were not accepted. The percentage of patients with symptom improvement after eradication therapy for Helicobacter pylori infection was calculated. Cumulative odds ratio was compared by fixed effect model and random effect model as sensitivity and funnel plot was used to evaluate publication bias. Results: The overall effect size of symptom improvement was calculated by cumulative odds ratio. Cumulative odds ratio of random effect model was 4.16(95% CI: 1.55-11.19). Before integrating each effect sizes into common effect size, the homogeneity test was conducted and random effect model was selected(Cochran's Q=41.08 (d.f=10, p<0.001)). The heterogeneity across studies was evaluated and the different methodological aspects of studies led to differences between study results Conclusions: The results suggest that the eradication of Helicobacter pylori in patients with non-ulcer dyspepsia results more symptom improvement. In studios that shows the opposite results there are methodological aspects explaining the heterogeneity.

A total of 30 cases of the peptic ulcer in children, who underwent operations from January 1981 to December 1995 because of complications at Department of the Surgery, Chonbuk National University Medical School, is reviewed. Twenty-three were males (76.7%), 7 females (23.3%) and male was preponderant at 3.3:1. There were 25 cases (83.3%) age 10 to 15 years, 3(10.0%) between 2 and 9 years, and 2 (6.7%) below 2. The ulcer was located at duodenum in 27(90.0%), and at stomach in 3 cases (10.0%). Complications were perforation in 19 cases (63.3%), pyloric obstruction in 9 (30.0%) and bleeding in 2 (6.7%). For perforation, truncal vagotomy with pyloroplasty was done in 11 cases, truncal vagotomy with hemigastrectomy and gastrojejunostomy in 6, and simple closure in 2 cases. For obstruction, truncal vagotomy with hemigastrectomy and gastrojejunostomy was done in 5, and truncal vagotomy and pyloroplasty in 3 cases. For bleeding lesions, truncal vagotomy and pyloroplasty was performed in 2 cases. Ten postoperative complications developed in 9 patients: adhesive ileus in 5, recurrence in 2, pneumonia 2, and wound seroma 1 case. One patient developed a primary duodenal perforation and another a recurrent obstruction. Both of patients had symptoms for more than 3 years and were treated with truncal vagotomy and pyloroplasty for the primary operations. Hospital stay was 11.5 days for the patient with perforated ulcer, 11.0 days for the patient with pyloric obstruction, and 14.5 days for the child with bleeding. Average hospital period was 11.6 days. To reduce recurrences after operation, extensive procedure such as distal gastrectomy with vagotomy at the first operation should be considered in case with severe complication or with patients who have been symptomatic for long periods.
