Ulcerative colitis is diffuse inflammatory condition at mucosal lining of the colon & rectum and rare in Korea but there are no pathognomonic features or specific diagnostic tests. However, recently the diagnostic methods for ulcerative colitis are much developed and the incidence of ulcerative colitis is increased in Korea. Therefor, an analysis of 31 cases of ulcerative colitis which was diagnosed and treated in the department of the YeungNam University Hospital from May l983 to April 1991 was reviewed. The results were as following: 1) The sex distribution assumed a ratio of 1 to 2.1 and the age distribution was vqriable but the most prevalent age group was 5th decade(29.0%). 2) The most common clinical manifestations were abdominal pain & bloody diarrhea. 3) As to the extent of disease determined by the barium enema & endoscopy, rectum or rectosigmoid colon was involved in majority of the cases 22.6%, 41.9 (respectively). 4) Significant laboratory findings were elevated ESR, anemia, leukocytosis, hypoalbuminemia. 5) The endoscopic examination was performed in all 31 cases and showed sinificant findings such as hyperemia, mucosai edema, superficial ulceration & mucosal friability. 6) 23 of 26 cases treated by sulfasalazine medication showed improved, and 3 cases were improved by steriod medication and the surgical operation was indicated in 1 case.

PURPOSE: To describe radiologic findings of burn-associated persistent candidemia of the thorax. MATERIALS AND METHODS: This study included 42 patients with major burns in whom blood culture had shown the presence for more than 24 hours of persistent candidemia. The duration of positive culture for candidiasis ranged from two to 67 days(mean, 15 days). Radiographic(n=42) and thin-section CT findings(n=13) were retrospectively analyzed. The onset, pattern, size, distribution and persistence of parenchymal abnormalities as well as the presence or absence of pleural effusions, mediastinal lymphadenopathy and cardiomegaly were assessed. RESULTS: On chest radiographs, positive findings were noticed in 61.9%(26/42) and on thin-section CT, in 76.9%(10/13). The most frequent radiographic finding was pulmonary nodule(s), observed in 14 patients(33.3%). in 13, these were bilateral. Bronchovascular bundle thickening(n=6, 14.3%), consolidation(n=4, 9.5%), cardiomegaly(n=6, 14.3%) and pleural effusion(n=4, 9.5%) were also observed. Those lesions appeared eight to 129 days(mean, 33days) after the burn. Radiographic abnormalities persisted for seven to 115 (mean, 35) days, regardless of the treatment. Thin-section CT showed parenchymal abnormalities in 10/13 patients(76.9%) and subpleural nodules of less than 1cm in diameter and without halo in all patients. Cardiomegaly, pleural effusion and mediastinal adenopathy were observed on CT in 5(38.5%), 4(30.8%) and 2(15.4%) of the 13 patients, respectively. CONCLUSION: In a high proportion of patients with burn-associated candidemia, chest radiograph and thin-section CT findings were positive. The most frequent radiographic parenchymal abnormality was multiple bilateral nodules.

Plummer-Vinson syndrome is a clinical entity characterized by dysphagia, iron deficiency anemia, cheilosis, glossitis, and cervical esophageal web, especially in middle aged women. Recently, the authors experienced a case of Plummer-Vinson syndrome. A 53-year-old female was admitted due to intermittent solid food dysphagia for 18 months. She had a 2 years history of iron deficiency anemia. On admission glossitis, fissures at the angle of the mouth, spoon nails, and iron deficiency anemia were noted. Esophagogram and esophagoscopic examination revealed thin walled concentric web at upper esophagus. Esophageal web was succefully teared by endoscopic balloon dilatation with subseguant improvement of dysphagia. Skin manifestations as well as anemia were markedly improved after oral iron replacement therapy.

OBJECTIVES: Hemodynamic measurements of chronic portal hypertension were done to study the mechanisms that maintain high portal pressure despite well developed collateral circulations. METHODS: A prehepatic portal hypertensive rat model was produced by partial portal vein ligation. Cardiac output, organ blood flow and porto-systemic shunt were measured by radioisotope labeled microsphere methods, and vascular resistance was calculated by standard equation. RESULTS: There was a significant reduction in the weight of the liver and increase in the weight of the spleen in the portal stenotic rats. Porto-systemic shunting, representing development of the collateral circulations, was 96.7+/-0.6% in the portal stenosis group compared with 0.9+/-0.2% in the control group (p<0.01). Portal pressure was significantly increased in the portal stenosis group compared with the control group(12.8+/-1.4 vs. 6.5+/-0.6mmHg; p<0.01). Mean arterial pressure was significantly decreased in portal stenosis group compared with control group(101.4+/-2.5 vs, 129.9+/-3.9mmHg; p<0.01). In the portal stenosis group, cardiac output(135.7+/-8.0 vs. 111.0+/-4.2ml/min; p<0.01) and splanchnic organ blood flow (28.97+/-2.03 vs. 17.90+/-1.27ml/min, p<0.01) were significantly increased, with concomitant decrease in total peripheral vascular resistance(58.0+/-3.3 vs. 88.2+/-4.8 dyne sec/cm5 X 105; p<0.01) and splanchnic vascular resistance(2.54+/-0.20 vs. 5.47+/-0.33 dyne sec/cm5 X 105; p<0.01), However, the portal venous resistance was not significantly different in both groups of rats (3.57+/-0.31 vs. 3.03+/-0.38 dyne sec/cm5 X 105; p>0.05). CONCLUSION: The hemodynamic results of this study indicate that hyperdynamic status of systemic and splanchnic circulation was present in chronic portal hypertension and that the primary factor contributing to the persistently elevated portal venous pressure was the markedly increased portal venous inflow.

PURPOSE: To characterize MRI findings of central nervous system(CNS) granulocytic sarcoma (chloroma) and to analyse the points which differentiate it from other CNS tumors. MATERIALS AND METHODS: We evaluated MRI in six patients with CNS granulocytic sarcoma proven by surgery or bone marrow biopsy (intracranical, one case and spine five cases). A 0.5T superconductive MR machine was used for diagnosis and, axial, coronal and sagittal T1- and T2-weighted spin echo images and Gd-DTPA enhanced T1-weighted images were obtained. We retrospectively analized the location, signal intensity, margin, contrast enhancement and homogeneity, and bony change around the tumor. RESULTS: MRI findings of CNS granulocytic sarcomas were as follows : one tumor was seen to be an extra-axial mass in the posterior fossa of the brain, four were epidural, and one was an epidural and presacral masses in the spine ; tumor magins were lobulated and three were smooth. On T1-weighted images, all tumors were of isoignal intensity; on T2-weighted images, four were of isosignal intersity and two were of high signal intensity. Contrast enhancement was inhomogeneous in five of six cases. Bony change around the tumor was seen in two cases. CONCLUSION: On T1-weighted images, CNS granulocytic sarcomas (chloromas) were of isosignal intensity, relative to brain parenchyma or spinal cord ; on T2-weighted images, they were of iso or high signal intensity, with relative contrast enhancement. These points could be useful in differentiating them from other CNS tumors.

BACKGROUND: Although current dietary guidelines recommend to increase the consumption of whole grain, these recommendations are mainly derived from the belief that replacing fats with carbohydrate may reduce risk of coronary artery disease (CAD) by improving serum lipids. Our objective was to evaluate whether the isocalorical replacement of refined rice with whole grain reduce CAD risk factors such as insulin demand and lipid peroxidation in CAD patients. METHODS: Thirty-eight male patients with CAD were provided with 70 g powder of whole grain (220 kcal) for 16 weeks, replacing cooked refined rice as a carbohydrate source of breakfast. An oral glucose tolerance test (OGTT) was performed in all subjects to determine the effect of whole grain consumption on serum concentrations of insulin and glucose in CAD patients with different degree of glucose tolerance. RESULTS: With the substitution of whole grain for refined rice, serum glucose concentrations decreased by 24% without altering body weight and energy intake. Estimates of daily fiber and vitamin E intakes increased by 24% and 50%, respectively. Whole grain consumption in CAD patients without diabetes decreased fasting glucose (22%) and the area under the curve (AUC) for insulin (26%) and glucose (19%) during an OGTT. CAD patients with diabetes also showed reductions in fasting glucose (27%) and AUC for glucose (25%) during the OGTT, compared with baseline values. Whole grain consumption reduced plasma malondialdehyde and homocysteine and urinary 8-epi-prostaglandin F 2alpha concentrations by about 30%. Lipid-corrected concentrations of alpha-carotene, retinol, alpha- and gamma-tocopherol and lycopene increased by 22-46%, compared with baseline values. Whole grain consumption decreased the percentage composition of w6 fatty acids of serum phospholipid increased by 14%. CONCLUSION: The replacement of refined rice with whole grain as a carbohydrate source of a meal showed significant beneficial effects on glucose, insulin and homocysteine concentrations and lipid peroxidation in CAD patients. These effects are likely to substantially reduce the risk factors of CAD and diabetes in CAD patients.

From January 1988 to December 1994, endoscopic sphincterotomy with stone extraction was attempted in 395 patients with common duct stones at Yeungnam University Hospital. Endoscopic sphincterotomy was successful in 389 patients(98.5 %), and clearance of the duct was achieved in 364 patients with an overall success rate of 92.2%. After sphincterotomy, stone extraction by basket or balloon was undertaken in 298 patients without lithotripsy, and stones could be extracted after fragmentation of stones in 19 patients. In 47 patients, stones were passed into duo denum spontaneously. There were 6 cases of sphincterotomy failure due to large periampullary diverticulum or previous gastrojejunostomy. In patients with success ful sphincterotomy, endoscopic stone extraction was failed in 25 cases due to 14 large stones, 5 bile duct strictures, 4 impacted stones, and 2 cases of technical fail ure. Complications were developed in 13 patients(3.3%); 8 pancreatitis and 5 bleedings. All of them were improved with medical therapy only. Despite relatively high success rate and low complications of the endoscopic management of choledocholithiasis, there were significant difficulties in removing large stones. Developement of more effective and inexpensive methods of lithotripsy, and the search for rapidly effective solvent dissolving stones were needed.

We report a case of cystic adenocarcinoma of the prostate in a 67-year-old man who showed severe obstructive voiding symptoms. In this case, the mechanism of the cyst formation from the prostate cancer is thought to be related to the secondary cystic formation, which was due to either the central necrosis of the cancer tissue or intracancerous tissue hemorrhage. Prostate cystic adenocarcinoma is a rare disease, and there are only a few cases reported in the literature. A cyst of the prostate may be either congenital or acquired. A congenital cyst arises from the mesonephric (Wolffian) or paramesonephric (Mullerian) duct system, while an acquired cyst is subdivided into the retention, malignant, and parasitic cyst. A huge prostatic cyst was found in a 67-year-old man. The lesion was presumed to be a prostate cystic adenocarcinoma.
