DSA was done in 133 examinations of 128 patients during 2 years consist of 9 examination of IV DSA and 124examination of selective cardiac DSA after cardiac catheterization. Open heart surgery was performed in 90patients and 12 patients showed discrepancy between pre-and post operative diagnosis, showing a total 86.7% ofdiagnostic accuracy with DSA. We experienced the significant reduction in dose of contrast media, 30-40% of doseof conventional cardiac heart disease. DSA is an accurate simple and safe method in evaluation of cardiac disases.

BACKGROUND: Nitric oxide(NO), a multifunctional mediator, is known as a endothelium-derived relaxing factor, a neurotransmitter, and a killer molecule formed by activated immune cells and participates in tissue destruction via apoptosis. In the skin, an increase in apoptotic cells has been desribed in the epidermis in various lichenoid diseases, in response, to ultraviolet radiation, and in neoplasia. OBJECTIVE: The purpose of this study is to investigate whether a positive correlation occurs between iNOS(inducible nitric oxide synthase) expression and apoptosis index in psoriasis vulgaris(PV), lichen planus(LP), and Bowen's disease(BD). METHODS: TUNEL staining and immunohistochemical staining with anti-iNOS antibody were done in paraffin-embedded tissue sections of 4 cases of PV, 4 cases of LP, and 2 cases of BD.

PURPOSE: To evaluate the relative value of arterial, portal venous and delayed phase images of spiral CT in the detection of metastatic tumor of the liver. MATERIALS AND METHODS: Forty-three metastatic tumors in twelve patients were underwent tri-phasic spiral CT examination with injection of 120 ml ionic contrast material (36 g of iodine) at the rate of 3 ml/sec. Arterial, portal venous and delayed phase CT images were obtained 35, 65, and 360 seconds after the start of contrast injection, respectively. RESULTS: Arterial phase images detected 35(81%), portal venous phase images 43(100%), and delayed phase images 34(79%) lesions, respectively(p<0.05). All masses larger than 2cm(n=23) were detected in all three phases, whereas 60%, 100%, 55%of the masses smaller than 2cm(n=20) were detected in arterial, portal venous and delayed phase CT, respectively. The best contrast between masses and the hepatic parenchyma was in portal venous phase followed by arterial and delayed phase(p<0.01). In two hypervascular masses, the contrast was better in arterial phase. CONCLUSION: Portal venous phase of spiral CT is optimal in the detection of metastatic tumor of the liver. Arterial phase may be helpful for the detection of hypervascular metastasis. Delayed phase should be used restrictively.

A finite element analysis has been utilized to analyze stress and strain fields and design a new configuration in orthopedics and implant dentistry. Load transfer and stress analysis at implant bone interface are important factors from treatment planning to long term success. Bone configuration and quality are different according to anatomy of expecting implantation site. The purpose of this study was to compare the stress distribution in maxilla and mandible according to implant length and bone engagement types. A three dimensional axi-symmetric implant model(Nobel Biocare, Gothenburg, Sweden) with surrounding cortical and cancellous bone were designed to analyzed the effects of bone engagement and implant length on stress distribution ANSYS 5.5 finite element program was utilized as an interpreting tool. Three cases of unicortical anchorage model with 7, 10, 13mm length and four cases of bicortical anchorage model with 5, 7, 10 and 13mm lenght were compared both maxillary and mandibular single implant situatiion. Within the limits of study, following conclusions were drawn. 1. There is difference in stress distribution according to cortical and cancellous bone thickness and shape. 2. Maximum stress was shown at the top of cortical bone area regardless of bone engagement types. 3. Bicortical engagement showed less stress accumulation when compared to unicortical case overall. 4. Longer the implant fixture length, less the stress on cortical bone area, however there is no difference in mandibular bicortical engagement case.

Eccrine nevus is a rare benign cutaneous lesion, frequently present at birth or at an early age. Herein we report on a 1-year-old girl with erythematous papules in a zosteriform arrangement associated with hyperhidrosis on the left side of her trunk.

OBJECTIVES: Developing mental health services and systems to identify children with Attention Deficit/Hyperactivity Disorder (ADHD) and providing early therapeutic interventions for them are important to prevent further impairments or disturbances associated with the disorder. The purpose of this study is to examine the clinical validities and efficiencies of Korean Child Behavior Checklist (K-CBCL) and Korean ADHD Rating Scale (K-ARS) for screening and identifying children with ADHD in community. METHODS: Randomly selected 1st to 3rd graders of the two elementary schools (n=1668) in the City of Gunsan participated in the study. K-CBCL and K-ARS were used as screening instruments. Diagnoses were determined by clinical psychiatric interviews and confirmed by Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version-Korean Version (K-SADS-PL-K) using DSM-IV criteria. RESULTS: The rate of inclusion above the T score of 60 with regard to the attention problems profile of K-CBCL was 4.5%. There was a significant correlation (p<.01) between parent and teacher reports of K-ARS, and the rate of inclusion was 2.5% when 90th percentile cut-off points were applied for both of the reports. Of the 46 subjects who underwent clinical psychiatric interviews, 33 (71.7%) were diagnosed as ADHD. The T score of 60 with regard to the attention problems profile of K-CBCL resulted in a reasonable level of sensitivity or positive predictive value in the diagnosis of ADHD. 90th percentile cut-off scores in both parent and teacher reports of K-ARS resulted in a high level of predictive value. The highest level of specificity and positive predictive value were computed when K-CBCL (T> or =60 in attention problems) and K-ARS (parent/teacher total> or =90th percentile) reports were combined. CONCLUSION: These findings suggest that the K-CBCL and K-ARS together could serve as a rapid and useful screening instrument to identify children with ADHD in epidemiologic case definitions.
