Aplastic anemia is a disease characterized by pancytopenia in the peripheral blood and hypocellular bone marrow with the fatty infiltration. The causes of the acquired aplastic anemia were usually related to drugs and immune-related diseases. A 34-years old man was admitted due to general weakness. He has been going hemodialysis for 2 years because of end stage renal disease (ESRD) due to chronic glomerulonephritis. At admission, laboratory tests showed hemoglobin 6.2 g/dL, hematocrit 18.0 %, WBC 5,710mm (neutrophil 71.8%, lymphocyte 19.1%, monocyte 5.9%), reticulocyte 1.9%, platelet 93,000/mm, Fe 12.8 ug/dL, TIBC 204 ug/dL, ferritin 941.47 ng /ml, haptoglobin 0.72 g/L, vitamin B12 508.17 pmol/L, folate 24 ng/mL, total protein 6.54 g/dL, albumin 3.76 g/dL, Alk. pohsphatase 79 IU/L, AST 30.0 IU/L, ALT 39.7 IU/L, total bilirubin 0.57 mg/dl, BUN 79.4 mg/dl and creatinine 10.18 mg/dl. Peripheral blood smear showed the normocytic normochromic anemia with anisocytosis. Anemia was diagnosed but it was irresponsive to the recombinant human erythropoietin (EPO) and blood transfusion. In the bone marrow aspiration smear were there the hypoplastic myeloid and erythroid precursors. The bone marrow biopsy section showed the hypoplasia of all components (10-20%) and the fatty infiltration. We have experienced one case of the idiopathic aplastic anemia in a patient going through hemodialysis and we just report it with documentary records. 저자들은 혈액 투석 중인 환자에서 약물, 면역계 이상등의 원인을 발견할 수 없었음에도 재생 불량성 빈혈이 발생한 1예를 경험하여 문헌 고찰과 함께 보고하는 바이다.

In Korea, the proportion of 65-year-old elderly population were gradually increased and over 7 percentage in 2000. To care elderly properly, various type of healthcare institutions is needed. There is general hospital and long-term care hospital among medical institution. In this study, difference of functional status and severity between elderly inpatients in general hospital and those in long-term care hospital was investigated. Comprehensive functional status of 577 patients that were hospitalized in 3 long-term care hospitals and 2 general hospitals was examined. On the contrary to our expectation, patients in long-term care hospital had lower activities of daily livings and more severe medical conditions than those in hospital. These results suggested that healthcare system and healthcare resource distribution for elderly patients are not worked efficiently.

Background: Some cases of QT interval, corrected QT interval (QTc), QT dispersion (QTd) and corrected QT dispersion (QTcd) have been reported in ESRD, but these results are variable and the influence of a hemodialysis is still controversial, In this study, we investigated the effect of hemodialysis on QT and QTc interval and QT and QTc dispersion in patients with ESRD 15 min before and 15 minute after each hemodialysis. Methods: Sixty-seven patients with ESRD (men 33 & women 34) on three-times stable hemodialysis (>3 months) were randomly enrolled. Fifty control subjects with a similar age and normal renal function were enrolled from this hospital. Routine biochemical studies were measured pre- and post dialysis, at the time of the ECG. Plasma Na+, K+, BUN, creatinine, ionized calcium and phosphate were checked. Twelve-lead electrocardiographs were performed at 10㎜/mv and 50㎜/s using a HewIett-Packard Pagewriter 100, before and after a single hemodialysis session.The QT interval was measured from the onset of the QRS complex to the end of the T wave. If the end of the T wave was not clear in a particular lead then it was excluded from analysis. When U waves were present, the end of the T wave was taken as the nadir between the T and U waves. Each QT interval was corrected for heart rate using Bazett's formula (QTc==QT/√(RR)) (ms). The difference between maximal and minimal QT interval duration was defined as QT dispersion (QTd) in each of the 12 leads. Result: This study demonstrates that QT, QTd, QTcd is higher in hemodialysis patients compared with control subjects, and QT and QTd rise postdialysis to levels comparable to those seen acutely following myocardial infarction, when patients are at greatly increased risk of potentially fatal ventricular arrhythmias, Conclusions: QT interval and QT dispersion, markers of risk for arrhythmias and sudden death, are elevated in hemodialysis patients, and rise postdialysis. QT interval and QT dispersion is an easily obtainable, noninvasive, simple, inexpensive, and widely available method of risk stratification in uremic patients receiving chronic dialysis. Additional studies are needed to clarity whether increased postdialysis QT dispersion results in an increased occurrence of arrhythmias.

Objectives A neural circuit including amygdala, the hippocampal complex and prefrontal cortex was associated with deficits in facial processing in schizophrenia. These deficits have a significant impact on social functioning in schizophrenia. Both neuropsychological deficits and brain structural abnormalities in first-degree relatives of schizophrenia patients suggest that they may also have the deficit in facial information processing as genetic factors. The purpose of this study was to explore the dysfunction of facial information processing in first-degree relatives of schizophrenia patients using functional magnetic neuroimaging (fMRI). Methods Ten non-affected siblings of schizophrenic patients and 10 normal comparison subjects having no schizophrenic siblings underwent fMRI during the dynamic facial change procedure consisting of presentations of facial emotion and gender discrimination stimuli. The emotion discrimination condition consisted of the presentation of 12 happy faces and 12 disgust/fear faces. The gender discrimnation condition consisted of the presentation of 12 male faces and 12 female faces. Condition-specific brain activations were compared between non-affected siblings and normal comparison subjects Results The facial information processing related brain regions including fusiform gyrus, several areas of frontal, temporal, occipital, and cerebellar regions exhibited more activation during gender discrimination than emotion discrimination tasks in each group. During gender discrimination task, siblings of schizophrenic patients showed less activation in right fusiform gyrus, both middle and superior frontal gyrus, left cuneus, and left inferior frontal gyrus, compared with normal comparison subjects. Conclusion Dysfunctional facial information processing, such as a deficit in gender discrimination, might be an endophenotype of schizophrenia.

Background: Hyperkalemia is a commonly encountered problem in dialysis patients with end-stage renal disease. In this study we evaluated the effect of mineralocorticoid therapy (fludrocortisono acetate) on serum potassium level in the serum of hyperkalemic end-stage renal disease patients. Methods: Fourteen patients on hemodialysis receiving fludrocortisone acetate (FCA) 0.1 mg/day were observed for 2 months periods. Consecutive monthly biochemical profiles were compared for the druration of the pre-and post-treatment of FCA. Result: Fourteen patients with mean age (±SE) of 51.5 years (4 males and 10 females) and mean hemodialysis period of 51.9 months were studied. Mean serum potassium levels significantly fell (p<0.05) during the post-FCA period (5.2±0.66 mEq/L) compared with potassium levels during the pre-FCA (5.8±0.43 mEq/L) period. Pre-and post-FCA values were not different for sodium, chloride, protein, albumin, AST/ALT, glucose, blood nitrogen, creatinine, phosphate and calcium. Conclusions: FCA appears to decrease serum potassium value in patients with end-stage renal disease. These results suggested that FCA could be effective to treat hyperkalemia without any adverse effect in patients undergoing hemodialysis.

The purpose of this study was to estimate the microbial quality of some raw vegetables, and suggest a safer method for their sanitization and pre-preparation in foodservice operations. Baechu-geotjeori was monitored from the ingredient to the final product, during different holding temperature. Three sanitization methods were performed during the pre-preparation (tap water, chlorine water and electrolyzed water). The largest reduction in the microbial counts was shown with the electrolyzed water pre-preparation (after treatment; the total plate counts decreased to 3.34-4.06 Log CFU/g, coliform counts decreased to 1.40-1.45 CFU/g). Prior to immersion in the chlorine water, washing was first performed to see if the was a larger effective reduction in the microbial counts.
