Clinical study was carried out on the 64 hemodialysis patients(HD) with chronic renal failure who had been treated from December 1992 to July 1993 in Yeungnam University Hospital. The following results were obitained. In hematologic parameters, MCH was 28.8±2.0pg, and MCV was 92.4±4.7fl. Result revealed normochromic and normocytic anemia. Mean values of serum ferritin were 657.4±292.0ng/ml in men and 511.5±370g in women. Mean values of serum iron were 145.5±63.7µg/dl. Mean values of transferrin saturation was 61.6±28.4%. Serum frerritin, serum iron and transferrin saturation were higher in HD group than normal reference. In erythropoeitin treatment group, Hb and Hct were significantly higher than non-erythropoietin treatment group. Amount of transfusion was significantly higher in non-erythropoietin treatment group than erythropoeitin treatment group(p<0.05). Values of iron, transferrin saturation were significantly higher in abnormal liver function test(LFT0 hemodialysis group than normal LFT group(p<0.05). Transfusion amounts revealed positive correlation with ferritin(r=0.4675), transferrin satruation (r=0.3823) and iron(r=0.3386) (p<0.05).

PURPOSE: The purpose of this study is to assess the clinical utility of multiplanar reformation images of helical CT in the evaluation of pancreatic diseases. MATERIALS AND METHODS: Helical CT scans of the pancreas were obtained in 30 patients with pancreatic diseases. Helical CT was performed with 5mm collimation at 5mm/sec table speed during rapid injection of intravenous contrast agent using power injector. After scanning, helical volume data were reconstructed at 2mm interval and then multiplanar reformation of the pancreas and adjacent structures was done. In both prospective reconstructed axial images and multiplanar reformation images, detection of pancreatic lesion, extent of lesion, and vascular and bile ductal changes were analyzed with a grading system of 1,2, 3. RESULTS: The mean grade of detection of pancreatic lesions was 2.37 in the prospective axial image and 2.83 in multiplanar reformation image, extent of diseases was 2.40 in prospective axial image and 2.97 in multiplanar reformation image, and vascular and bile ductal changes was 2.00 in the prospective axial image and 2.97 in multiplanar reformation image. All the differences were statistically significant (P<0.0001). CONCLUSION: Multiplanar reformation images of helical CT are useful in the evaluation of pancreatic diseases and especially in the demonstratibn of complex anatomic relationships between the pancreas and surrounding structures.

BACKGROUND: Diabetic ketoacidosis(DKA) is serious acute metabolic complication and the most important cause of high morbidity and mortality of diabetes. The object of this study is to examine the clinical characteristics of patients with DKA who had a prior history of diabetes or not. METHOD: Authors reviewed retrospectively the medical records of 49 cases adimitted to Kyungpook National University Hospital from January 1991 to June 1997 with a diagnosis of DKA and classified cases as type I, type II and newly diagnosed diabetics according to prior history of diabetes. RESULTS: 1. Of 49 cases of DKA, 24(49%) were classified as type I, 17(35%) as type II from data available in the medical records, and 8(16%) had DKA as the initial manifestation of the disease. 2. The male to female ratio was 0.5 : 1 in type I, 1.1 : 1 in type II and 1.7 : 1 in newly diagnosed diabetics, and the mean age was 24.4 in type I, 57.9 in type II and 23.9 years old in newly diagnosed diabetics. 3. The mean duration between initial diagnosis of diabetes and the occurrence of DKA was 2.6 in type I and 6.9 years in type II diabetes. The occurrence of DKA within 2 years of initial diagnosis of diabetes was 54% in type I and 18% in type II diabetes, but the occurrence of DKA after 5 years of initial diagnosis of diabetes was 17% in type I and 47% in type II diabetes. 4. The precipitating factors of DKA were identified in 88% in type I, 76% in type II and 38% in newly diagnosed diabetics, and the most common precipitating factor was omission of treatment in both type I and type II(type I: 56%, type II: 35%). 5. The altered mental status was correlated with increased osmolality (p<0.05), but not with other laboratory values such as pH, bicabonate, glucose, anion gap and dehydration status(p>0.05). CONCLUSION: It is necessary to conduct early aggressive evaluation for early diagnosis and proper treatment of DKA, because DKA occurs in patients with prior history of type II diabetes and without prior diabetic history as well as patients with prior history of type I diabetes.

BACKGROUND: This study aimed to empirically investigate the determinants on oxygen free radical degree which causes biological damage focusing on smoking habit and health behaviors in daily life. METHODS: In this cross-sectional study, the subjects were adult males who submitted free radical tests among the examinees of the comprehensive medical testings at an university hospital in Suwon from 2008 to 2010. Total 497 samples were used in analyses for clarifying the relations of free radical degree to age, smoking, obesity, and other health behaviors. RESULTS: First, the degree of oxygen free radical increases by 0.164 as the age group increases (P<0.05). Second, the degree of oxygen free radical increases by 0.547 as the smoking habit increases (P<0.001). Third, the degree of oxygen free radical increases by 0.087 as the exposure to hazardous factors in workplace increases (P<0.001). CONCLUSIONS: The findings of the study imply that the smoking habit has more great influence on the increase of oxygen free radical in body than any other health behaviors. The causality of free radical to smoking and health behavior was not identified due to the limit of the cross-sectional study so it needs to be studied prospectively in the future.

Neuromyelitis optica (Devic disease) is a rare demyelinating disorder of unknown etiology in which unilateral or bilateral optic neuritis and transverse myelitis occur within 8 weeks. The disease has no clinical involvement beyond the spinal cord or optic nerves. This illness occurs more commonly in adults than in children. The prognosis is better in children than in adults. The authors experienced a case of neuromyelitis optica (Devic disease) in a 5-year-old female who developed acute visual loss of the left eye, paraplegia, sensory change above the 4th thoracic dermatome, nuchal rigidity and fever. We diagnosed this case through neurologic features, magnetic resonance imaging, ophthalmoscopy and cerebrospinal fluid findings. The patient improved with conservative treatment without sequelae.

In the course of immunoscreening of Clonorchis sinensis cDNA library, a cDNA CsRP12 containing a tandem repeat was isolated. The cDNA CsRP12 encodes two putative peptides of open reading frames (ORFs) 1 and 2 (CsRP12-1 and -2). The repetitive region is composed of 15 repeats of 10 amino acids. Of the two putative peptides, CsRP12-1 was proline-rich and found to have homologues in several organisms. Recombinant proteins of the putative peptides were bacterially produced and purified by an affinity chromatography. Recombinant CsRP12-1 protein was recognized by sera of clonorchiasis patients and experimental rabbits, but recombinant CsRP12-2 was not. One of the putative peptide, CsRP12-1, is designated CsPRA, proline-rich antigen of C. sinensis. Both the C-termini of CsRP12-1 and -2 were bacterially produced and analysed to show no antigenicity. Recombinant CsPRA protein showed high sensitivity and specificity. In experimental rabbits, IgG antibodies to CsPRA was produced between 4 and 8 weeks after the infection and decreased thereafter over one year. These results indicate that CsPRA is equivalent to a natural protein and a useful antigenic protein for serodiagnosis of human clonorchiasis.

BACKGROUND: Fundus photographs performed during health check-up were reviewed to determine the usefulness in mass screening. METHODS: Subjects consistine of 3017 people who had undergone physical health check up at the Health Clinic, Dong-Eui Medical Center in 1997 and whose fundus photographs of both eyes were taken showing clearly visible posterior pole and optic disc were chosen as subjects. Medical records which included cases of reported close exam and causes, actual cases of close exam and final diagnoses. RESULTS: Of the 3017 people, reported close exam was performed in 665 (22.0%). Among them glaucoma was suspected in 460 retinal hemorrhagic lesion in 63, retinal degenerative lesion in 67 and others in 75. There were 187 actual cases(28.1%) of close exam including glaucoma suspect in 79, retinal hemorrhagic lesion 47, retinal degenerative lesion 34 and others 27. Among 187 actual cases of close exam, 140 people (1.3%) were eventually diagnosed as glaucoma suspect (60), retinal hemorrhagic lesion (38), retinal degenerative lesion (21) and others (21). CONCLUSIONS: Fundus photographs are useful in mass screening, but performing close exam to enhance the usefulness of the fundus photographs is necessary.

BACKGROUND: There has been a change in the causes of aortic stenosis when comparence of rheumatioc aortic stenosis in recent year. Therefore, we studied the etiology factor of pure aortic stenosis. METHODS: The gross surgical pathologic features of the aortic valves were reviewed in 92 patients with pure aotic stenosis whom underwent aortic valve replacement at Yonsei University, Cardiovascular center between July 1989 and June 1994. RESULTS: The three most frequent causes were 1) calcification of congenital bicuspid valve in 30%, 2) degenerative calcification of aortic valve in 22%, 3) rheumatioc valvular change in 48%. The mean age at the time of aortic valve replacement for the entire series of patients was 54.4 years. The range of age was from 18 years to 77 years. Males predominated for degenerative disease and congenital bicuspid valves, but there were reversed rheumatic origin. One or more complications occured in 17% of patients undergoing operation. The surgical mortality was 3.3%. CONCLUSION: Our data suggest that more common cause of aortic stenosis is non-rheumatic disease rather than rheumatinc origin.
