The isolation of fetal cells from maternal circulation has the potential to allow relativelyself prenatal diagosis for all pregnant women. The present technology, however, has notreached the accuracy required for clinical diagnosis because of maternal cell contaminationSo we published a new method for enrichment of nRBC in a fetal cell isolation(1996).In this study, attempted to FISH analysis of nRBC which was isolated by our ownmethods. We evaluated the efficiency of FISH.As the results, we have successfully used FISH on enriched nRBC.We were able to identified 2 abnormal fetus which were confirmed by conventionalcytogenentic study as Down syndrome(Fig.1) and Klinefeltre syndrome(Fig.2). And thesensitivity and specificity for FISH was 86%(49/57) and 92.3%(36/39), respectively.According to our results, fetal cell analysis by FISH can be reliable used for prenatalaneuploidy diagnosis. However, the problems of enrichment of the fetal cell and FISH probeor condition should be over come before analyze.

Primary epiploic appendagitis (PEA) occurs due to inflammation of an epiploic appendage, which is a peritoneal pouch that arises from the serosal surface of the colon. PEA is often associated with infarction caused by torsion or spontaneous venous thrombosis. PEA is a self-limited disease with a course of approximately 10 days, and it requires only symptomatic management for pain. But it clinically manifests with localized abdominal pain that is often mistaken for appendicitis, diverticulitis, or cholangitis. Therefore, PEA had been diagnosed at surgery for the past few decades. Making the preoperative diagnosis of PEA through ultrasound and computed tomography (CT) has recently become possible. We report here on four cases of PEA that were diagnosed and treated by symptomatic management.

PURPOSE: In acyanotic congenital heart disease of children with left to right shunt, 99mTc- Macroaggregate albumin (MAA) was employed to determine the scintigraphic severity of pulmonary parenchymal damage. METHODS: These data of lung perfusion scan using 99mTc-MAA were compared with hemodynamic values obtained from cardiac catheterization. RESULTS: The mean Pulmonary arterial pressure (> or = 30mmHg), total pulmonary resistance (> or = 2 Wood unit) & ratio of pulmonary vascular resistance/systemic resistance (Rp/Rs > or = 0.2) were proportionally related to higher perfusion ratio of upper and lower lung field. The diagnostic values of perfusion ratio of upper & lower field of both lung (cut off value > or = 0.8) for pulmonary hypertension were as follows : 60-65% of sensitivity, 75-90% of specificity, 72-86% of positive predictive value & 68-69% of negative predictive value. The mottled perfusion defect was frequently found in patients with pulmonary hypertension (mean pulmonary arterial pressure > or = 30mmHg, Rp > or = 2 Wood unit). The degree of perfusion defect as indicator of severe pulmonary parenchymal damage was utilized clinically as determinator of operability and morbidity for acyanotic shunt lesions perioperatively. CONCLUSION: The scintigraphic severity determined by 99mTc-MAA lung perfusion scan could be valid for evaluating the extent of pulmonary parenchymal damage in acyanotic congenital heart disease complicated by pulmonary hypertension.

PURPOSE: We retrospectively investigated to find out the equation of calculating the probability of minimal change nephrotic syndrome (MCNS) using clinical parameters. We prospectively investigated to determine the usefulness of the mathematical model. METHODS: We retrospectively examined 56 patients with nephrotic syndrome (NS) (30 MCNS and 26 non-MCNS) diagnosed by kidney biopsy. A mathematical model for calculating the probability of MCNS was obtained through multiple logistic analysis in SAS statistics package. In addition, we prospectively studied 28 patients with NS. Clinical MCNS and non-MCNS were classified according to the probability of 85% in the mathematical model. Kidney biopsy was performed, and serum albumin and urinalysis were measured after 2 weeks of steroid treatment. RESULTS: In the retrospective study, the mathematical model was P=ea/(1+ea), a=17.2507 - 5.5777xON - 4.2256xALB-0.000579x24PROT - 1.2569xUBL+2.1703xUAL. The mode of onset (ON), 24 hours urine protein (24PROT), serum albumin concentration (ALB), the grade of hematuria (UBL) and proteinuria (UAL) were included as clinical parameters. At the probability of 85%, the sensitivity and specificity for predicting MCNS was 73.3% and 100% respectively. In the prospective study, the result of kidney biopsy was consistent with clinical MCNS and non-MCNS according to a mathematical model. All clinical MCNS showed negative proteinuria on urinalysis and a significant increase in serum albumin after 2 weeks treatment (1.85+/-0.30 g/dL to 2.88+/-0.26 g/dL, p<0.05). CONCLUSION: We conclude that the mathematical model for predicting the probability of MCNS may be useful in diagnosis of the MCNS.

BACKGROUND: Rhabdomyolysis is a well known cause of the exercise induced acute renal failure (ARF), but the patch renal vasoconstriction with severe loin pain which developed after the anaerobic exercise is not. Although there are a few cases about ARF resulted from the patchy renal vasoconstriction in Korea, there are only a few reports about comparisons of their clinical manifestations. METHODS: Eight patients of ARF with severe loin pain after the exercise, were admitted to Chungbuk national university hospital from April 1994 to March 2004. For all patients, we obtained basic clinical findings and laboratory studies, and performed an enhanced computed tomography (CT) initially and delayed CT without contrast media at least 6 hours after. RESULTS: All the patients were previously healthy young men. The main symptom was loin pain in five patients and all patients experienced the anaerobic exercise before. Six patients took analgesics and fever was observed in seven patients. There was no marked elevation of creatinine phosphokinase (CPK). The initial mean creatinine (Cr) was 3.50+/-1.49 mg/dL and the maximum Cr was 8.8 mg/dL. All the patients fully recovered their renal function. We observed the typical patchy wedge-shaped contrast enhancement CT findings in seven patients. CONCLUSION: Differential diagnosis between rhabdomyolysis and the patchy renal vasoconstriction in newly developed ARF after exercise is important. Our eight patients showed typical clinical manifestations. In cases which implicate the pathy renal vasoconstriction by their typical clinical findings, the enhanced CT and the delayed postcontrast CT are helpful for diagnosis.

Objectives ; This study was conducted to reveal the health effects of aircraft noise on the residents live near the military airport. METHODS: We sampled systematically 87 residents as the high exposed group, 58 residents as the low exposed group according to the geographical distance from the airport. We also sampled 67 residents as the control group lived far from the airport. Noise levels were measured for conform the exposures. Self-administered questionnaires for symptoms, air conduction hearing threshold level, blood pressure blood cholesterol with health examinations, and SCL-90-R were introduced to get the data from the residents. RESULTS: The Ld/n at the area near the airport was 72.4 dB, however that of control area was 67. 7 dB. The value of pure tone average, high pure tone average, and threshold of 4,000 Hz were decreased with exposure level significantly. Linear regression analysis showed that the noise exposure level of the airport was related to the hearing threshold at pure tone average, threshold of 4,000 Hz, and high pure tone average. The systemic and diastolic blood pressure showed dose-response relationship with noise exposure. The prevalence of hypertension was higher in exposed group, but not statistically significant. In linear regression, noise level was related to systolic and diastolic blood pressure with other variables such as age, sex, BMI (Body Mass Index), and family history of hypertension. SCL-90-R showed that exposed group had higher score significantly in neurotic and psychologic variable and felt the various somatic symptoms. CONCLUSIONS: These results suggest that aircraft noise would influence hearing loss at low frequencies as well as 4,000 Hz and higher frequencies, systolic and diastolic blood pressure, and psychological response.

BACKGROUND: Recently, G1 cells, characterized by distinctive doughnut-like shape with blebs have been reported as a reliable marker for glomerular hematuria. We investigated the validity of the urinary G1 cells in distingushing glomerular from non-glomerular hematuria. In addition, we evaluate the influence of urine osmolality, pH and proteinuria on dysmorphic erythrocytes and G1 cells. METHODS: One hundred and twenty patients with hematuria including 60 glomerular (GH) and 60 non- glomerular hematuria (NGH) were examined. The percentage of urinary dysmorphic erythrocytes and G1 cells using phase-contrast microscopy was determined. Urine osmolality, pH, and spot urine protein/ creatinine ratio were examined. RESULTS: The proportion of G1 cells differed significantly between the two group (7.8+/-16.0% in GH vs. 0% in NGH, p<0.05). At the cut-off value of 50 % dysmorphic erythrocytes, the sensitivity and specificity for the detection of GH was 88.3% and 93.3%, respectively. At the cut-off value of 1% G1 cells, sensitivity and specificity were 60.0% and 100%, respectively. When both of 50% dysmorphic erythrocytes and 1% G1 cells were considered as the cut-off value, the sensitivity and specificity were 91.0% and 100%, respectively. There was a significant difference in the percentage of dysmorphic erythrocytes and G1 cells at different urine pH. There was a significant correlation between urine osmolality and dysmorphic erythrocytes (r=0.41, p< 0.05), but not for G1 cells. No significant correlations were observed between G1 cells and proteinuria or pH. CONCLUSION: Evaluation of both urinary G1 cell and dysmorphic erythrocytes at the same time could improve the diagnostic value for differentiating glomerular hematuria.

Terlipressin has splanchnic vasoconstrictive effects, and is generally used for the management of gastroesophageal variceal bleeding secondary to liver cirrhosis. Terlipressin is a synthetic arginine vasopressin (AVP) analog containing a nonapeptide sequence. Terlipressin has increased selectivity for the V1 receptor, compared with AVP; hence, it is considered to be a safe vasoconstrictor. However, side effects such as hyponatremia and seizure, although very rare, have been reported. Hyponatremia related to terlipressin may be caused by the syndrome of inappropriate antidiuresis (SIAD), which is a disorder of sodium and water balance characterized by hypotonic hyponatremia without elevation of the antidiuretic hormone level. Here, we report a case of hyponatremic seizure induced by an infusion of terlipressin in a 52-year-old female who had isolated gastric variceal bleeding secondary to alcoholic liver cirrhosis.
