A study on the optimal drying condition by a vacuum drying oven was done using shredded tobacco lamina and commercial cigarettes ('This'). Changes in the mass of the experimental material were monitored for about 50 hrs at 6 different temperatures (5$0^{\circ}C$~10$0^{\circ}C$, 1$0^{\circ}C$ stepwise) while continuously operating a vacuum pump. After 30 hrs, small amount of samples from each material were taken sequentially to monitor changes in moisture content using a Karl-Fischer method (Metrohm KF 701 Titrino). Absolute moisture contents calculated from the measurements indicated an ideal data distribution could be obtained by drying at temperatures between 7$0^{\circ}C$~8$0^{\circ}C$. Results from cigarette products which contains humectant and tobacco lamina without it were compared.

N/A Objectives: Hyperlipidemia is well-known as one of the major risk factors of atherosclerotic heart disease. Previous reports indicate that reduction of meat and dairy product consumption has reduced development of coronary heart disease. This study was designed to assess prospectively the difference in blood level of various lipids and coronary artery disease risk between vegetarian and non-vegetarian in Korean adults. Methods :100 vegetarians and 82 non-vegetarians were recruited for lipid test including total cholesterol, triglyceride, HDL-cholesterol, Apo A-I and Apo B during annual routine physical examination. Coronary risk and relative risk were analyzed according to the Framingham study data base using computerized calculation with variables including cholesterol, age, sex, blood pressure, smoking history and diabetes. To evaluate the influence of diet to coronary disease risk, 42 vegetarians and 97 non-vegetarians without other coronary risk factors were analyzed same manner, Result: 1) Total cholesterol was significantly lower in vegetarian groups (group A: 161.4mg/d1±6.76, group C: 160.62mg/dl±28.8) compared to non-vegetarians groups(group B: 180.65mg/dl±5.13, group D: 189.05 mg/dl 37.8)(p<0.01). 2) Other lipid values did not show significant difference. 3) Coronary risk was significantly lower in vegetarian groups compared to non-vegetarians(group A : 1.48% vs. group B: 1.78%; group C: 2.0% vs. group D: 6%). 4) Relative risk was also significantly lower in vegetarian groups compared to non-vegetarian groups (group A: 0.75±0.31 vs. group B: 1.00±0.41; group C: 0.74±0.2 vs. group D: 1.09±0.44) Conclusion: This study shows vegetarian group has significantly lower total cholesterol level and reduced coronary heart disease risk compared to non-vegetarian group.

N/A Backgroud/Aims: Helicobacter pylori infection is closely associated with chronic gastritis and peptic ulcer. The recurrence rate of duodenal ulcer within 12 months after treatment is seventy to ninty percent. However, many studies have demonstrated that the eradication of H. pylori infection had reduced the relapse rate of duodenal ulcer significantly. Methods: We have investigated a short term H. pylori eradication regimen consisting of Colloidal Bismuth Subcitrate(CHS) 240 mg b.I.d for two weeks, omeprazole 20 mg s.d for two weeks, amoxacillin 250 mg t.I.d for one week. Our study included 150 patients with duodenal ulcers confirmed by endoscopy. Results: Eight-four percent of those patients were CLO test positive. Following two weeks of therapy, ninty-seven percent of patients had healing ulcers confirmed by endoscopy and 84.7% of patients, previously urease positive, had converted to urease negative. The eradication rate of H. pylori(using the CLO test) determined at four weeks after the treatment was fifty-two percent. Conclusions: During the course of treatment, none of the patients experienced any significant side effects. The triple regimen therapy appears to be safe and well tolerated. We have concluded that the triple regimen therapy is an effective treatment of H. pylori positive duodenal ulcer in our trial group. (Korean J Gastroenterol 1996;28:617 - 622)

The first case report of granular cell tumor was by Abrikossoff in 1926, the tumor has been named with more than 20 different synonyms. It is found usually in the tongue, oral cavity, and the skin. It occurs rarely in the esophagus. Esophageal granular cell tumor is a benign lesion which can be diagnosed by endoscopic biopsy. Large symptomatic lesion can be removed by polypectomy. A 29-year-old female visited our hospital for intermittent epigastric pain and anterior chest discomfort. Endoscopy showed a 0.6 *0.4 cm whitish yellow nodule in the mid-esophagus, 25 cm from the incisor teeth. Endoscopic polypectomy was performed with $quot;O$quot;-type rubber band for endoscopic variceal ligation(EVL). A case of esophageal granular cell tumor conformed by S-100 protein stain is reported with the review of literature.

Chronic lymphocytic leukemia (CLL) of T cell origin (T-CLL) is extremely rare but one case has reported in Korea. We have experienced a case of T4-CLL, which was confirmed by immunophenotyping panel and monoclonal antibody of lymphocytes and we want to present the case with a review of the literature. A 86-year-old woman admitted to the department of internal medicine Seoul Adventist Hospital on September 9th, 1993 with febrile sensation end multiple itchy eruptions on face and both extremities. Homoglobin was 10.2g/dl, hematocrit 32.2%, reticulocyte count 2.7%, platelet 221,000/㎣ and white blood cell count was, 71,000/㎣ with 5% segments and 79% lymphocytes. Albumin was 3.5g/dl and total globulins were 8.2g/dl. Quantitative immunoglobulins were within normal limits. Bone marrow aspiration and biopsy was done. Myeloid series showed normal distribution, erythroid series revealed normoblastic erythropoiesis. Lymphocytes were increased in number (40%). Marrow cellularity was 50% and mature lymphocytes were increased in number by interstitial type. The results of surface marker studies of leukemic cells were SmIg: IgG 16%, SmIg: IgM 7%, SmIg: Lambda 17%, Smig: Kappa 10%, Monoclonal antibody tests of leukemic cells were T1: 96%, T3:93%, T4:98%, T11:99%, Ia:74%, 3A1:93% and J5, b1, B4 were negative.

Background/Aims: The clinical severity of gallstone pancreatitis is known to be more intense than that of alcoholic pancreatitis. However, it is still controversial whether the etiology is risk factors for the pronosis of acute pancreatitis (AP). This study was designed to elucidate the role of etiological factors on the prognosis and severity in AP. Methods: We have retrospectively evaluated 216 patients (M:137, F:79) with AP during recent 6 years. The diagnosis of AP was based on the typical symptoms and signs, enzyme elevation and radiologic findings. Acute physiology and chronic health evaluation (APACHE II) and Ranson score at admission were used for grading the severity. Etiological groups were subdivided into alcohol, gallstone, idiopathic and others. Results: The causes of AP were alcohol (32.4%), gallstone (26.9%), idiopathic (23.1%) and others (17.6%). The clinical severity was not different between alcohol and gallstone pancreatitis. The mortality rate was 10% in patients with alcoholic pancreatitis, but no death was seen in patients with gallstone pancreatitis. Conclusions: The alcoholic pancreatitis was not severe than the gallstone pancreatitis in clinical severity, but the complication and mortality of the alcoholic pancreatitis were higher than those of the gallstone pancreatitis. The prognosis and mortality were influenced by etiological factors in AP.

Background/Aims: The usefulness of serum pancreatic enzyme deterrninations in the diagnosis of acute pancreatitis is well established. There are differences between clinical course and outcome due to the underlying etiological factors in acute pancreatitis. In this study we assess the ability of the serurn lipase/amylase ratio to differentiate the etiologies and to predict the severity of it. Methods: We evaluated retrospectively the records of 104 patients (M:64, F:40) with acute pancreatitis. The diagnosis of acute pancreatitis was based on the typical symptoms, signs, pancreatic enzyme elevation and radiological findings. Ranson, Glasgow and APACHE II at admission were used for grading of clinical severity. The patients were classified into four etiologic groups: alcohol, gallstone, idiopathic and others. Results: The ratio of underlying cause of acute pancreatitis were as follows: alcohol, 35.6%; gallstone, 27.9%; idiopathic, 22.1%; others, 14.4%. There were no differences in the serum amylase, lipase and lipase/amylase ratio among the etiological groups. The clinical severities of pancreatitis according to the Ranson, Glasgow and APACHE II were not related with the lipase/amylase ratio in pancreatitis. Conclusions: Evaluation of serum lipase/amylase ratio is not useful for assessing etiology and severity of acute pancreatitis.
