Free radical scavengers or quenching agents for reactive oxygen species(ROS) present in consumable fruits, vegetables, and beverages have received considerable attention as potential antioxidants, and thus uses for treatment of several human diseases. In this study, grapevine shoot extract(GSE) containing high concentration of resveratrol and viniferine was evaluated for antioxidant potential and inhibition of pro-inflam-matory medicator production. Utilizing 1, 1-diphenyl-2-picrylhydrazyl(DPPH) scavenging activity and xanthine oxidase(XOD) inhibition assay the GSE showed inhibitory effects of DPPH radical scavenging and XOD activity with the IC_50 values of 34.5 ad 155㎍/ml, respectively. In addition, GSE also exhibited the inhibition of prostaglandin E_2(PGE_2) and nitric oxide(NO) production in lipopolysaccharide(LPS)-induced mouse macrophage RAW264.7 cells with the IC_50 value of 6.4 and 14.5 ㎍/ml, respectively. This suggests that grapevine shoot extract has the potential activity as a natural antioxidant or antiinflammatory agent.

The study objective was to assess the ulcer healing effects of Teprenone, stimulator of mucus production, given in dose of 50mg tid. We reviewed 25 cases of gastric ulcer proven endoscopically and treated by Teprenone. The results were follows; 1) The healing rate of gastric ulcer was 72% after 8 weeks treatment. 2) Subjective symptoms such as epigastric pain, belching, nausea, anorexia and vomiting were subsided at 86%. 3) There were not developed any symptoms, signs and laboratory abnormality (CBC, liver funtion test, urinalysis) suggesting side effect of drugs. In conclusion, Teprenone was considered an effective and safe drug in the treatment of gastric ulcer diseases.

From January 1987 to October 1991, we performed 14,333 cases of upper gastrointestinal endoscopy and diagnosed 527 cases with U.G.I polyp. We assesed these 527 cases and obtained following results: 1) The overall incidence of U.G.I. polyps was 3.6%, and there was no sexual difference. The peak incidence was in 6th decades(32.4%). 2) The U.G.I. polyps were located chiefly at stomach(415 cases, 78.7%), among which antrum occupied antrum 43.5%, body 24.0% and funds 5.1%. And the others were esophagus(6.5%) and duodenum(12.3%). 3) The size of U.G.I. polyp was below 1cm in 72.3%, from 1cm to 1.9cm in 20.7% and above 2cm in 7.0%. According to Yamada' classification, type Ⅰ, Ⅱ, Ⅲ and Ⅳ was 31.9%, 51.3%, 13.7% and 3.0%. 4) Histological nature of U.I.G. polyp were hyperplastic polyp(85.8%), adenomatous polyps(9.3%), carcinomatous polyps(3.3%) and etc. The size of neoplastic polyp such as adenomatous polyps(mean 1.0±0.7cm) and carcinomatous polyps(niean 2.0±1.8) were larger man hyperplastic polyp(mean 0.6±0.4) (p<0.05) 5) The gastric polyps were associated with peptic ulcer(7.5%), gastric cancer(3.2%), other malignancy(3.5%), hepatobiliary disease(5.5%), post subtotal gastrectomy(5.5%). And others(75%) werenot associated with specific disease.

For the patient with stenosis of upper digestive tract caused by either benign or malignant process, esophageal dilatation is an important therapeutic modality. We reviewed retrospectively 39 cases treated by Savary-Gilliard dilatation for upper digestive tract stenosis, and results were follows : (1) Dysphagia was improved in 95% of the patients. (2) Eight patients(20%) sufferd perforation, five of them were managed with conservative medical measures, others were managed operatively. (3) In the cases with benign stenosis dysphagia was not noticed for 8.8 months, but with malignant stenosis dysphagia was reappeared after 2.8 months despite concomitant chemoradiotherapy. In conclusion, Savary-Gilliard dilatation was an effective measure for symptome due to upper digestive tract stenosis, but more careful attention for perforation should be necessitated. Also another therapeutic modality for treatment of malignant stenosis was inevitable.

The prevalence of antibody against hepatitis C virus (anti-HCV) was investigated in 331 patients with various liver diseases from April 1992 to September 1992. The presence of anti-HCV was detected by Lucky HCD EIA test in 331 cases and by (Ortho HCV Antibody ELISA test 148 patients) The results are summarized as follows: 1. Overall, antibody to HCV(anti-HCV) was positive in 37(11%) of 331 patients with various liver diseases. 2. 16(11%) of 144 patients with chronic hepatitis, 2(5%) of 37 patients with alcoholic liver disease, 17(22%) of 76 patients with liver cirrhosis and 2(5%) of 38 HBsAg carriers were positive for anti-HCV.None of 12 patients with acute hepatitis, 11 patients with drug induced hepatitis and 13 patients with hepatocellular carcinoma was anti-HCV positive. 3. HBsAg positivity in patients who had anti-HCV was 24%(9/37). 4. A positive correlation was found between Lucky HCD and Ortho HCV test. Of 128 Lucky HCD negative cases, 124 cases were negative for Ortho HCV ELISA and 4 cases were positive for Ortho HCV ELISA Of 20 Lucky HCD positive cases, 11 cases were positive for Ortho HCV ELISA and 9 cases were negative for Ortho HCV ELISA. These results suggest that hepatitis C virus has an important etiologic role in HBsAg negative chronic hepatitis and liver cirrhosis in Korea. The diagnostic value of Lucky HCD EIA test may be slightly better or equivalent to Ortho HCV ELISA test in the diagnosis of Hepatitis C virus infection.

Background : More than 90% of acute stroke patients have measurable cardiovascular sequelae, but we have been often overlooked in formal discussions of treatment. If we estimate the incidence of myocardial injury in patients with spontaneous SAH, we may figure the possibility of cardiac dysfunction in such patients. This study was designed to investigate the incidence of myocardial injury in patients with spontaneous SAH using cardiac troponin I(cTnI). Methods : A prospective single emergency center study was performed to determined preoperative incidence of unrecognized cardiac injury in patients suffering spontaneous SAH. We include the spontaneous SAH patients who underwent serum measurements of the cardic troponin I immediately upon admission last six month period. ECG, CK, CK-MB and myoglobin were also performed at admission. We excluded the spontaneous SAH patients who had past history of myocardial ischemia and ECG abnormality. Results : Fifty-two patients(34 females, 18 males) with spontaneous SAH were studied prospectively. 18 patients(34.6% of the total study population) had cTnI level above 0.5ng/ml. ECG was performed in 52 patients and was abnormal in 15 of the 52 patients(28.8%). Conclusion : The measurement of cTnI has provided physicians with a myocardial marker that has a cardiac sensitivity for cardiac injury equal to that of CK-MB yet with greater specificity. So, cardiac troponin I is useful to estimate the incidence of myocardial injury in patients with spontaneous SAH. And we may estimate the possibility of cardiac dysfunction in such patients. This knowledge will hopefully aid in the care and improve the outcome.

40세 이전에 폐경이 되는 조기 폐경의 원인으로 자가면역질혼, 방사선 치료, 항암제 투여, 난소 제거, 염색체 이상 등이 잇지만 대부분 그 원인을 알 수 없으며 최근 들어 조기 폐경의 가족성 발병에 근거한 유전학적인 원인이 주목받고 있다. 특히 취약 X 증후군 (FRAXA)의 보인자와 조기 폐경이 관련이 있다는 보고가 있어, 특발성 조기 폐경 환자에서 유전학적인 원인 인자로서 FRAXA premutation의 중요성을 입증하기 위해 본 연구를 시행하였다. 염색체 검사상 염색체 이상 소견이 없으며, 조기 폐경의 원인이 밝혀지지 않은 83명의 조기 폐경 환자를 대상으로 실험을 시행하였다. 이들 환자 83명을 대상으로 FMR1 유전자에 대한 PCR과 Southern blot analysis를 시행한 결과 3명 (3.6%)이 취약 X 증후군의 보인자임을 확인하였다. 이는 원인 불명 조기 폐경 환자에서 취약 X 증후군 보인자의 빈도가 일반인에서보다 현저히 높음을 의미하며, FMR1 유전자와 난소 기능과의 연고나성을 나타내는 결과이며, 나아가 취약 X 증후군의 예방적인 차원에서 원인 불명 조기 폐경 환자에서 취약 X 증후군 보인자의 선별 검사의 필요성을 나타내는 실험 결과라고 할 수 있다. Objective : To explore the incidence of fragile X premutation in patients with idiopathic premature ovarian failure, particularly in the Korean population. Design : A prospective study. Materials and Methods : Eighty-three women affected by idiopathic premature ovarian failure were recruited for this study. Patient with known causes of premature ovarian failure were excluded : cytogenetic abnormalities, prior chemotherapy, prior bilateral oophorectomy. DNA was extracted from peripheral blood. Fragile X (FRAXA) premutation was evaluated by PCR amplification of and Southern blot analysis for FMR1 gene. Results : The FRAXA premutation was detected in three (3.6%) out of 83 patients with idiopathic premature ovarian failure. Conclusion : This result suggests that fragile X premutation screening is indicated in patients with idiopathic premature ovarian failure, particularly in the Korean population.
