Helicobacter pylori infection was the cause of chronic gastritis, duodenal ulcer and gastric MALT lymphoma. The eradication rates of H. pylori using antibiotics are around 80%. Lactobacilli have been demonstrated to have in vivo and in vitro inhibitory effects on H. pylori infection. We aimed to evaluate the inhibitory effect of L. lactis CBT-8 and its extract on H. pylori in human stomach. Thirty-five H. pylori-infected volunteers(30-49 yr)were randomized into two groups which were treated with L. lactis CBT-8 and its extract(Group A n=17) or milk containing L. lactis CBT-8(Group B, n=18). They underwent 13C-urea breath tests before and after treatment. The DOB30 of group A(n=14) was decreased 41.0% after treatment(26.0±4.9 before, 15.3±2.1 after treatment)(p<0.05). the DOB30 of group B(n=13) was decreased 22.3% after treatment(22.0±2.2 before, 17.1±1.7 after treatment)(p<0.05). In conclusion, L. lactis CBT-8 was effective in suppressing H. pylori infection in human stomach.

본 연구에서는 오존의 당일예보모형 2개(중회귀모형, 판별분석모형)를 선정하고 상호 비교·평가함으로써 모형들이 갖는 특성을 대기오염 관리대책에 반영시키기 위한 연구를 수행하였다. 고농도 오존계절의 분석 결과로부터 4월~8월의 5개월(153일)간의 기간을 광화학스모그 발생가능성이 높은 계절로 선정하였고, 오존농도의 일변화 특성은 오전 8시경부터 점점 증가하다가 오후 2~4시경에 최고점에 달하는 것으로 나타났고, 오존농도의 지역특성을 요인분석을 통하여 분석한 결과, 서울시 전체지역(최소한 반경 15km 이내)의 오존농도 변화특성을 하나의 모형으로 설명하는 데 큰 무리가 없음을 알았다. 모형작성 및 검정·검증을 행하고 상호 비교한 결과, 판별분석 모형이 예상했던 바와 같이 임의의 고농도일 만을 주목한 경우에는 중회귀모형 보다 약간 더 좋은 결과를 보여 주었고, 전반적인 경우에는 두 모형이 비슷한 결과를 나타내었다. Based on of analyzing the season of high level of Ox(Oxidant), five months from April to August were selected. As a result of investigating the weather effect on high level of Ox days and the diurnal variation of Ox, it was observed that the temperature was comparatively high, the wind velocity was very low, and the irradiation intensity was very high. It was found that hourly Ox increased from 8 A.M. and reached its peak by 2~4 P.M. As a result of factor analysis, an area characteristic of Ox could be explained by only one model for the whole area of Seoul(at least within 15 km of a radius). It was proved that a discriminant model is better than a multiple regression model in case that a high level of Ox is concerned, but in general two models were alike. Therefore, in view of photochemical Ox control strategy, it is thought that a discriminant model is more useful than a multiple regression model, in case that the excess of a certain warning criteria is important than any other cases.

소나무로부터 직접 배출되는 주요한 모노테르펜 물질로 α-pinene, camphene, myrcene, β -pinene, α-phellandrene, α-terpinene, d-limonene, p-cymene, β-phellandrene 등이 확인되었다. 7년생 소나무에서 직접 배출되는 모노테르펜 물질의 구성비를 분석한 결과 β-pinene이 67.0%로 가장 높았고, 22년생 소나무 경우에 β-phellanone이 37.4%로 가장 높았으며, 32년생 소나무는 α-pinene 구성비가 약 42.9%로 가장 높았다. 소나무는 수령에 따라서 구성비에 큰 차이를 보였으며, 소나무 수령이 높을수록 α-pinene이 구성비가 높았다. 소나무의 수령별 α-pinene과 β-pinene의 비율(α-pinene/β-pinene)을 비교한 결과, 7년생 소나무의 경우 0.16~l.15 범위로 나타났고, 22년생 소나무의 경우 0.64~2.47로 나타났으며, 32년생 소나무의 경우 0.50~18.47 범위로 나타났다. α-pinene과 β-pinene의 비는 수령이 높아질수록 좀 더 높은 값을 보였고, 동일한 수령일지라도 나무에 따라서 차이를 보였다. The major monoterpenes emitted from the Pinus densiflora were α-pinene, camphene, myrcene, β-pinene, α-phellandrene, α-terpinene, d-limonene, p-cymene and β-phellandrene. As a result of comparison of monoterpene composition by tree age for P. densiflora, it was found that β-pinene was a dominant monoterpene for 7-year-old pine(67%). β-Phellandrene(37.4%) and α-pinene(46.1%) were most abound for 22-year-old pine and 32-year-old pine respectively. The ratio of monoterpene composition varied considerably with tree age for the pine, and the percentage of α-pinene composition increased with tree age. The ratio of α-pinene and β-pinene(α-pinene/β-pinene) increased with tree age, and varied tree to tree.

This research is aimed to define how the depression, performing ability of IADL and muscular-skeletal pain of the Aged, according to their residential circumstance, sex and age, can affect the subjective health index and how all these are related and associated with. For the period of June 1 to July 31,2000, in order to study and define how the depression, performing ability of IADL and muscular-skeletal pain are related to the subjective health index of the Aged, we have conducted an enquete through a direct interview with 693 persons over age sixty-five (65) in Daejon and in other adjacent areas, divided into three different residential types "The Aged living at home", "The Aged living at welfare facilities" and "The Aged living alone". We have studied all the data and information obtained through this enquete and have analyzed χ2_test, t-test, ANOVA, analysis of simple correlation, analysis of factor. by SPSS10.0/PC+. The results were as follows : Generally, the four (4) factors depression, IADL performing ability, muscular-skeletal pain and the subjective health index of the Aged, are a lot influenced by and related to their residential circumstance, their sex and their age. With regard to the depression of the Aged by their sex, it was analyzed that, on an average, the female-Aged gains 48.3 point which reflects comparatively the higher points and the female-Aged is more depressed. In analyzing depression of the Aged by their age, it appears that the Aged between eighty (80) to eight-four (84) years of age, gains 49.2 point which is the highest points and simultaneously we could realize that depression follows age, - the more the age gets, the more the depression is increased. In analyzing depression of the Aged by their residential type, it shows that "the Aged living alone" gains 50.9 point and is most depressed. With regard to the IADL performance of the Aged by their sex, it was analyzed that, on an average, the female-Aged gains 23.8 point, which shows the performance of the female-Aged is less independent. In addition, it was also found that the IADL performing ability is becoming less and less independent following their age increasing. In analyzing IADL performance by their residential type, it appears that "the Aged living at welfare facilities" gains the lowest 21.5 point and is least independent. We conclude that some assistances from others are required for the Aged living at welfare facilities in their performing IADL. With regard to the muscular-skeletal pain of the Aged by their sex, it was analyzed that, on an average, the female-Aged gains 3.0 point and the female-Aged surfers from this pain more severely. In analyzing this pain by their residential type, it was found that, on an average, the 3.0 point goes for "the Aged living alone", which explains the Aged living alone is having the most serious pain. With regard to the subjective heath index of the all Aged participated in this research, the analysis indicates 8.8 point and this is considered as a general standard (7-10 point). In analyzing this index by their sex, the female-Aged gains 8.6 point only and it explains a lot of female-Aged consider they are not really healthy. In analyzing this index by their residential type, "the Aged living at welfare facilities" and "the Aged living alone" gain the comparatively lower point, - respectively 8.4 point for the Aged living at welfare facilities and 8.8 point for the Aged living alone. The Aged of these two residential types express they are obviously in a bad condition of health, which makes us think a lot. With regard to the factors affecting the subjective health index of the Aged, it was analyzed that this index can significantly be influenced by their depression, their pain, their age and by how much they are satisfied with their current living conditions, and also analyzed that the correlative relation certainly exists between the depression and pain, and the subjective health index, - that is, the more the depression and pain are serious, the lower the subjective health index indicates. As for the IADL, it appears that the IADL's relation with this index is not that significant and even not important.

Chronic eosinophilic pneumonia(CEP) is a rare disease of unknown etiology characterized by chronic infiltration of the lung with eosinophils. It presents with profound systemic symptoms comprising fever, night sweats, weight loss, dyspnea and blood eosinophilia with nonsegmental air-space consolidation confined to the outer third of the lung, the "photographic negative of pulmonary edema". Histopathologic features of chronic eosinophilic pneumonia are intraalveolar and interstitial infiltrations with eosinophils, histiocytes, giant cells, scattered lymphocytes and plasma cells. Glucocorticoid therapy cause prompt resolution of symptoms as well as disappearans of blood eosinophils, elevated serum Ig E levels and the roentgenographic lesions. Infrequent radiographic findings include nodular infiltrates, consolidations, cavitations, atelectasis and pleural effusions. Deaths from CEP although rare, have been reported, but the majorities of CEP have benign courses and do not need a therapy with ventilator. We report a case of chronic eosinophilic pneumonia, which had a sudden course associated with diffuse pneumonic consolidations on the both lung and bilateral pleural effusion.

Objectives : To figure out the factors related to the failure of primary pulmonary tuberculosis(Tb) treatment and to enhance the efficiency of the treatment. Methods and Materials : The subjects were 137 Tb patients composed of the two groups; 44 failure cases and 93 success cases who admitted in National Masan Tuberculosis Hospital during 2001. The failure means no improvement with the standard short term regimen of INH and RFP. Patients' informations were gathered through medical records and face-to-face interview survey, and, the data were analyzed with SPSS(ver 10.0). Results : Mean age of the subjects were 47.6 years. Most cases were diagnosed at clinics or hospitals at first, due to the symptoms. No difference in smoking and alcohol habits between the two groups. The cases who got the informations about the whole process of treatment, and following regular regimens were more in the success group. The proportion of multi-drug resistance to the regular primary Tb regimen was higher in the failure group 8 cases out of 25 detectable failure cases. 0 case among 46 successful cases. And the four regular regimen(INH, RFP, EMB, PZA) was popular type of the resistance. In chest X-ray, multiply involved lesion(≥ two lobes), atelectasis and pleurisy were more frequent in the failure group. Conclusion : The major factors that enhance the efficiency of Tb treatment were the informations and compliance. Enough explanation about the whole process would be essential during Tb treatment, and, in case of MDR-Tb, susceptible regimen and surgical therapy should be considered.

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.

In Korea, malignant lymphoma is a common cancer, comprising about 2.7% of all malignant neoplasm. Diffuse large B cell lymphoma is the most common lymphoma, representing about 50% of all Non-Hodgkin's lymphoma. Diffuse large B-cell lymphoma is usually considered as heterogeneous group of neoplasms rather than a single clinicopathological entity. Clinical prognostic systems, including the International Prognostic Index (IPI), although useful to assess overall prognosis, embrace patients with heterogeneous prognoses. But International Prognostic Index scoring system is not sufficiently predict the prognosis. It is likely that the prognostic assessment of patients with diffuse large B-cell lymphomamight be improved by using biological features. Bcl-2 protein and p16 protein expression is recognized as useful biologic markers predicting the prognosis of patients with diffuse large B-cell lymphoma. To determine the clinical significance and prognostic value of bcl-2 and p16 proteins expression patterns, we studied 18 patients with de novo DLBL, whose archival pathology specimen were available for immunohistochemistry studies, atChungnam National University Hospital from September 1992 to December 2000. Archival specimens from each patient were immunostained with respective antibodies for bcl-2, p16. The results are as follows; 1) The median age was 54(rage : 37-69). There were 12 male patients(66.7%) and 6 female patients(33.3%) The 'B' symptom was abscentin all patients. The stages were as follows : Ⅰ, 2 patient(11.1%), Ⅱ, 10 patient(55.6%), Ⅲ, 4patient(22.2%) and Ⅳ, 2patient(11.1%). 3 patients(16.8%) had the elevated LDH level, 14 patients(77.8%) had the normal LDH level and 1 patients(5.6%) was not identified the LDH level. 2 patients(11.1%) had the bulky disease and 16 patients(88.7%) had no bulky diease. The distribution of ECOG status were O, 2 patients(11.1%c), 1, 14patients(77.8%) and 2, 2patients(11.1%). 2) Theimmunohistochemistry results are as follows bcl-2:+,10 patients(55.6%), bcl-2:-, 8patinets(44.4%), p16:+,3 patients(16.7%), p16:-, 15patients(83.3%) 3) After a median follow UP durations of 67 months, the median survival time was 57 months with a rage of 7-100+ months. 5-years overall survival rates was 44% by Kaplan-Meier method. 4) Reduced overall survival was demonstrated in the patients who expressed bcl-2 protein(P=0.0174). 5-year overall survivial rate was 12%(bcl-2 expression) versus 88%(no bcl-2 expression) 5) Among diffuse large B-cell lymphoma patients with IPI score 0-1, reduced overall survival was demonstrated with bcl-2 expression(P=0.023). 5-year overall survival rate was 18%(bcl-2 expression group) versus 100%(no bcl-2 expressiongroup) 6) Median survival durtation of diffuse large B-cell lymphoma patients negative for p16 expression was 57 months whereas p16 postive patients' median survival duration was not reached(P=0.4478). In diffuse large B-cell lymphoma patients with identical IPI scores, bcl-2 expression had additional prognostic value.

Helicobacter pylori is the major cause of histologic chronic gastritis and is strongly associated with peptic ulcer disease, gastric cancer and lymphoma. Several recommendations for the management of the Helicobacter pylori infection have been developed. However, there has been no clear therapeutic regimen for the optimal treatment of Helicobacter pylori infection. This study was desinged to evaluate the eradication rate and the ulcer healing rate of the triple regimen with low-dose clarithromycin(0.5g/day) in peptic ulcer patients. Forty three patients with gastric ulcer(n=15) and duodenal ulcer(n=28) were enrolled. The patients were treated either with omeprazole 20mg b.i.d. amoxicillin 0.5g b.i.d. and clarithromycin 250mg b.i.d. (low-dose regimen group, n=29) or with omeprazole 20mg b.i.d., amoxicillin 1.0g b.i.d. and clarithromycin 0.5g b.i.d.(high-dose regimen group, n= 14) for 2 weeks. After 4 weeks, the patients were evaluated for the eradication of Helicobacter pylori and the healing of ulcer. And gastritis scores according to the Sydney system were evaluated before and after 4 weeks from the end of the triple regimen. There was no significant difference in the eradication rate and the ulcer healing rate between the low-dose regimen group, group and the high-does regimen group. In the low-does regimen group, the mean initial scores of chronic inflammation and activity were decreased after the eradication of Helicobacter pylori. In conclusion, the low-dose triple regimen is as effective as the high-dose triple regimen on the eradication of Helicobacter pylori and the ulcer healing rate in peptic ulcer disease.

Hypereosinophilic syndrome is characterized by persistent blood eosinophilia of 1,500/ul or more in the absence of known causes and multiorgan dysfunction by eosinophil-related tissue damage. In Korea, some cases of hypereosinophilic syndrome with hepatic involvement have been described with prolonged benign clinical courses. Most of them were diffuse or multifocal lesions in imaging studies, and a few case presenting as a single mass has been described. Here we report a case of hypereosinophilic syndrome with hepatic involvement in a 65-year-old man who presented with multifocal mass lesions. By abdominal US and CT scan, multiple, ill-defined nodules were detected in throughout the liver. Liver biopsy revealed severe eosinophilic hepatitis, suggestive of hypereosinophilic syndrome. Hepatic mass lesions improved after steroid administration for several weeks.
