OBJECTIVES: This study was conducted in order to examine the reliability and validity of the Children's Color Trails Test (CCTT). The objective of the study was also to provide the Korean normative data for the CCTT. METHODS: Normative samples consisted of 766 children and adolescents living in Seoul and aged from 5 to 15 years. Eighty children who were diagnosed with ADHD, based on the DSM-IV criterion, were recruited from Seoul National University Children's Hospital. Among them, 46 ADHD children were receiving medication, while 34 children were drug-free. RESULTS: The scores of the CCTT were significantly correlated with those of the Stroop test. Three factors were extracted through factor analysis.visual tracking and cognitive flexibility, distractibility and susceptibility to interference, and simple attention and impulsivity. The completion time of the CCTT for all children tended to decrease as age increased. There were significant differences in the CCTT scores between the ADHD group receiving medication, the ADHD-drug free group and the normal groups. The CCTT also showed sound test-retest reliability. These results confirmed the relia-bility and validity of the CCTT. Finally, we provided the Korean normative data for the CCTT. CONCLUSION: These results suggest that the CCTT is a reliable and valid test, which can be used to assess frontal function related to child psychiatric disorders in Korean children.

Clonorchiasis is known to be closely related with the development of recurrent pyogenic cholangitis and carcinoma of the bile ducts. In order to ascertain the cholangiographic signs for recurrent pyogenic cholangitis or carcinoma of the bile ducts arising in patients with clonorchiasis. we reviewed cholangiograms in 42 patients with proven clonorchiasis. The population consisted of 29 patients with clonorchiasis alone, six patients with clonorchiasis and recurrent pyogenic cholangitis, and seven patients with clonorchiasis and carcinoma of the bile ducts. Cholangiographic abnormalities in 29 patients with clonorchiasis alone, six patients with clonorchiasis and recurrent pyogenic cholangitis, and seven patients with clonorchiasis and carcinoma of the bile ducts. Cholangiographic abnormalities in 29 patients with clonorchiasis alone were intrahepatic multiple, oval, or elliptic filling defects measuring 2-10 mm in size, representing adult flukes (n=24). The peripheral bile duct were obstructed (n=18), and the margins were ragged (n=20) and hazy (n=12) the intrahepatic bile ducts were dilated diffusely (n=27), and the dilated peripheral small tributaries gave the impression of "too many ducts appearance" (n=7) and dilatation was mid (n=17) In six patients with clonorchiasis and recurrent pyogenic cholangitis, there were filling defects of stones, and the extrahepatic ducts and larger intrahepatic ducts were predominantly dilated. In seven patients with clonorchiasis and cholangiocarcinoma all the biliary tree proximal to the tumor was markedly and diffusely dilated In the latter two groups, filling defects of flukes and associated findings were less prominent, but there was disproportionately severe dilatation of too many intrahepatic ducts. In patients with recurrent pyogenic cholangitis or cholangiocarcinoma, clonorchiasis should be considered as a underlying cause when cholangiogram shows "disproportionately" severe dilatation of too many intrahepatic ducts. intrahepatic ducts.

It is essential to define the accurate location and extent of tumors for the treatment planning and evaluation of the prognosis of the musculoskeletal tumors. Since Magnetic Resonance Imaging(MRI) provides excellent tissue contrast and multiplsnar image. MRI could be applied to the diagnosis and the treatment planning of musculo-skeletal tumors. Thirty-one patients with bone and soft tissue tumors underwent MRI at Department of Orthopedic Surgery, Seoul National University Hospital, since Jun. 1986, and the applicability of MRI in treatment planning of bone and soft tissue tumors was evaluated. Multiplanar image and excellent tissue contrast between soft tissue made it possible to define the location and the extent of tumor accurately. Tl weighted image was advantageous in intramedullary tumor extent, while T2 weighted image was helpful in soft tissue invasion. It was possible to guess histologic diagnosis of tumor in such cases as hemangioma, aneurysmal bone cyst, lipoma, and desmoid tumor. Above advantages guided the treatment planning and determination of biopsy site. Especially in two cases of osteosarcoma, which were highly malignant, limb salvage operation was performed instead of amputation.

BACKGROUND: It is not clear how much amount is favourable to coronary heart disease, although cardioprotective effects of red wine were reported. Furthermore, there is no report showing the effects of soju, the popular liqour in Korea on endothelial function. We performed this study to know early effects of alcohol on endothelial function in healthy subjects according to the kinds and the amounts of alcohol. METHODS: Endothelial function was measured by using high-resolution ultrasound in 20 healthy subjects. Ten subjects were crossover studied according to the types of alcohol (120 cc of red wine and 45 cc of soju) and the other ten subjects were studied using the half dosage of the same alcohol. RESULTS: The endothelial function can be impaired during 1 to 2 hours after alcohol ingestion (Soju 45 cc and red wine 120 cc, p<0.05), then recovered to baseline level. However, these impaired endothelial functions were associated with an increased brachial artery diameter. The endothelial function was recovered to baseline level more earlier in case of red wine than that of soju 2 hours vs 3 hours. Red wine 60cc and Soju 22.5 cc can improve the endothelial function in healthy subjects 2 and 3 hours after ingestion, respectively. These effects were not related with vasodilatory effects of alcohol. CONCLUSION: This study suggests that small amounts of alcohol can improve the endothelial function in healthy subjects independently with the vasodilatory effects of alcohol.The amounts of alcohol showing beneficial effects on endothelial function were lower than our expectation (a half cup).
