Background : Lipoprotein lipase(LPL) is a key enzyme in the metabolism of serum triglycerides(TG) which is utilized in the peripheral tissue as free fatty acid and stored in adipose tissue. LPL gene is consisted of 10 exons which encode 475 amino acids and over 9 LPL gene polymorphisms have been reported. It's polymorphisms are related to the lipid levels and the severity of atherosclerosis in the coronary artery disease. In Korea, LPL polymorphisms has not been reported yet. This study is purposed on the incidences of LPL gene mutations and on it's relationships with blood lipid levels and the severity of atherosclerosis. Methods : Our subjects were consisted of three groups, normal controls(n=50), coronary artery disease(CAD, n=51) and cerebrovascular disease(CVD, n=52). The PCR amplified genomic DNA from peripheral white blood cell were analyzed with restriction fragment length polymorphisms (RFLP by two different restriction enzyme(PVU II, Hind III). Results : Total cholesterol(TC) were higher in CVD than in controls and in CAD (203±60mg/ dl vs 188±37, 167±42, p<0.01). Triglyceride(TG) were also elevated in CAD(166±65mg/dl vs 122±62 in controls, p<0.05). HDL cholesterol(HDL-C) were higher in controls than in CVD and CAD(49±9mg/dl vs 36±10, 44±9, p<0.05). The incidences of Hind III RFLP and PVU II RFLP has no differences among groups. Only HDL-C was elevated in Hind III RFLP(-/-) homozygotes. Conclusions : The LPL gene mutations in intron 6 and 8 have no direct effects on the lipid profiles and the severity of coronary artery disease. Although LPL is a key enzyme in TG metabolism, two mutations in this study could not change the activity of LPL, nor were not a marker of linked other site mutations. The mutation(s) in exon which encode amino acid for enzyme activity should be detected to analyze the pathophysiology of the atherogenesis.

For more effective intraperitoneal chemotherapy, the authers made 5-fluorouracil-polyglycolic acid composite disks(FU-PGA disks) with 5-fluorouracil and polyglycolic acid, a biodegradable polymer. We inserted the FU-PGA disk into the peritoneal cavites of Sprague-Dawley male rats, the control and three experimental groups; one FU-PGA disk insert group(300mg/kg), two FU-PGA disk insert group(600mg/kg), and three FU-PGA disk insert group(900mg/kg). The control group received a similar number of PGA disk inserts. A pharmacokinetic study was performed to measure the 5-fluorouracil concentration in the peritoneal fluid, blood, and tissues(liver, kidney and heart) at 24 hours, 72hours and 168 hours after insertion of the FU-PGA disk. Light and electron microscopic studies were done. The results were as follows: 1) The number of white blood cells and platelets decreased after FU-PGA insertion. The degree was proportional to the duration and amounts inserted. The change in the number of red blood cells varied slightly. 2) Light microscopically, slight changes were noted at 168 hours in the 3 disk insert group (900mg/kg). Mild fatty change and hepatocyte degeneration around the central veins of the liver were noted, with vacuolar degeneration in the proximal convoluted tubules of the kidney. 3) Electron microscopically,the liver showed focal increases of lipid droplets in the hepatocytes, and irregular nuclear membrane with focal nucleolar segregation of the fibrillar and granular elements. Also the double membranous structure of the hepatocytes and Kupffer cells was widened with bleb formation. The kidney showed wide separation of the nuclear double membrane in the proximal convoluted tubular cells and mesangial cells, with vacuolation and myelin figure formation in the mitochondria of the proximal convoluted tubular cells, at 72 hours and 168 hours in the 2 to 3 FU-PGA insert groups. The heart showed focal loss of cristae,vacuolation and myelin figure formation in the mitochondria of the 2 to 3 FU-PGA insert groups. In conclusion, despite the large amont of FU-PGA inserted, the histopathological changes in the liver, kidney and heart were slight, and consonant with the very low amount of 5-fluorouracil concentrations detected in the liver, kidney and heart. The above results suggest that the FU-PGA composite can serve as a new device for releasing drugs in a controlled manner and easily targeted to intraperitoneal organs. This device can improve the efficacy of intraperitoneal chemotherapy for gastric cancer.

Background/Aims: Inflammatory diseasas of the pancreas are not uncommon. The advanced age is one of the significant factors in assessing the severity of acute pancreatitis. It has been shown that the biliary tract disease is a more frequent cause of acute pancreatitis in the elderly than in the young. With the increased life span, the elderly are comprising a large proportion of the population. As a result, physicians are more often being faced with acute pancreatitis in the elderly. The purpose af this study was to evaluate clinical features of acute panereatitis in the elderly. Methods: A total of 188 patients with acute pancreatitis were reviewed. We investigated the differences of clinical characteristics between the elderly patients aged over 60 and the young patients aged under 60. Results: The sex distribution showed male preponderance in the young patients (M:F=2.4:1), but was nearly equal in the elderly patients (M:F=1.1:1). The most common cause of acute pancreatitis in the elderly was biliary tract disease (52.5%), while alcohol abuse was the most common cause in the young patients (38.8%), Local complications of acute pancreatitis, such as psuedocyst, necrosis, abscesses were not differently shown between the elderly (16.9%) and the young (20.2%) patients. Systemic complications including acute puhnonary failure occurred more frequently in the elderly patients than the young patients. The mortality rate of the elderly patients (5.1%) was not significantly different from that of the young patients (3.1%). Conclusions: To detect correctable underlying bihary tract diseases the elderly patients with acute pancreatitis should be completely investigated using endoscopic retrograde cholangiopancreatography (ERCP). In addition, the patient should be closely monitored for the development of the systemic complications during the disease process.

Background : Coronary disease is highly prevalent in patient with end stage renal disease (ESRD) and account for much of their observed morbidity and mortality. Troponin-I consistently maintains a high sensitivity and specificity and is most sensitive marker for ischemic heart disease (IHD). Method : We examed 49 hernodialyzed patients (22 male, 27 female) without evidence of acute coronary syndrome (ACS) for 6 months. Biochemical markers were measured in serial predialysis blood samples. For analysis, we used two cardio-specific assays for troponin-T (cTnT) as well as for troponin-I (cTnI) and compared the results with CK-MB (reference value ≤ 4.0 ng/mL) concentration. Results : Myocardial ischemia was observed in 47% (23/49) of patients. cTnT level above 0.1 ng/mL. and cTnI level above 0.5 ng/mL, were observed in 22% (11/49) and 20% (10/49) of patients respectively. cTnI revealed significantly higher positive rate in patients with myocardial ischemia than the patients without myocardial ischemia (43 % vs 30%) (p<0.05). cTnT and CK-MB revealed no difference in positive rate between the patients with and without myocardial ischemia (cTnT : 30% vs 15% and CK-MB : 30% vs 19%). The sensitivity and specificity of cTnI to myocardial ischemia were higher than those of cTnT and CK-MB (sensitivity 43% vs 30% and 30%. specificity 100% vs 85% and 81%). Conclusion: Both cTnT and cTnI are useful in ruling out myocardial injury in chronic renal failure patients. But. cTnI is a more sensitivity and excellent specificity of ischemic heart disease than cTnT and CK-MB in hemodialyzed patients. In patients with ischemic heart disease, the presences of DM and advanced age were higher than those in patients without ischemic heart disease (p<0.05). Among the baseline characteristics old age, elevated LDH and diabeties were significant more frequent in the patients with elevation of cardiac troponin-I (p>0.5 ng/mL) than those with cardiac troponin-I (p<0.5 ng/mL), p=0.038, p=0.049, and p=0.045, respectively. Our results suggest that these cTnI is the potential diagnostic marker for the prediction of IHD in ESRD patients.

N/A Clinical studies on patients with duodenal ulcer who visited endoscopy room of Kyungpook National University Hospital since 1976 were performed. Among these patients, we compared the number of patients with gastric or duodenal ulcer yearly, and some aspects of difference between 57 cases of old age(above 60 years) and 129 cases of young age(under 30 years) patients with duodenal ulcer. The results obtained were as follows. 1) In examined cases, number of patients with duodenal ulcer was progressively increased year by year and number of gastric ulcer was more prevalent than that of duodenal ulcer unti11979 when the ratio of gastric and duodenal ulcer became nearly same, and thereafter duodenal ulcer cases were begun more predominant about 2 times that of gastric ulcer in 1981 2) Comparing the sex distribution of old and young age group, male was predominant about 12 times of female cases in young age group and about 2.5 times in old. 3) Overall complications including bleeding, perforation, obstruction and others were seen in 63. 2% of old age group and in 48.1% of young. 4) In 8 weeks follow up cases that was possible although it was least in number, 8 cases were improved or healed in old age group but 5 cases out of 18 cases in young revealed no improvement by ordinary regimen.

The purpose of this study is to improve listening and speaking ability in English, and to help low-level students learn English more effectively through cooperative learning in small groups in high school English classes. For that purpose, the following hypotheses were established on the basis of the effectiveness of the cooperative learning in small groups. Hypothesis 1 : cooperative learning in small groups will have a positive effect on the students' interest in English learning and 4 skills of English. Hypothesis 2 : Cooperative learning in small group will help the students improve their listening and speaking ability in English by mutual activities. Hypothesis 3 : Cooperative learning in small groups will get the low-level students to learn English more effectively by the help of their fellow students. Subjects for the study were 50 students in the first grade of a high school in the Changwon city of area of Kyoungsangnamdo. The treatment group was made up of 50 students, and the normal group was made up of 48 students. The two groups were considered as equal groups in three achievement tests and the questionnaire about their interest in English. For about 9 months, the treatment group has been assigned to the cooperative learning in small groups, while the normal group has been assigned to the teacher directed whole-class learning. The effects of cooperative learning in small groups were examined in three areas : interest in English, listening and speaking ability, and the number of low-level students in achievement tests. Questionnaires about their interest in English were asked twice, before and after the experiment. Listening and speaking ability tests were given 3 times for each. General achievement tests were given 4 times to find out the low-level students^1). The results above indicated the cooperative learning in small groups turned out to be effective in improving the students' communicative ability and decreasing the number of low-level students. Therefore, it seems to be a very helpful teaching method worth applying in high school English classes. In conclusion, for beginners to improve their communicative ability, they should have enough opportunities to speak in class. And their teacher should not be the center of the class. I hope that further research will be systematically conducted in this area, and applied in high school English classes. It is also expected that this study can be helpful for the new curriculum starting from 2.002.
