In order to determine the intensity of infection with the encysted larvae of Metagonimus yokogawai among Plecoglossus altivelis, sweetfish, caught at the rivers in Kyungpook Province, Korea were examined in the period from July to October, 1976. The data were compared with the results obtained from Tribolodon hakonensis, the sea-run dace, caught at the river Hyungsan in the Province. A total of 128 Plecoglossus altivelis were examined. All the fish were infected with the metacercaria of Metagonimus yokogawai. The metacercarial rate for the fluke in the flesh was higher than the rates in the fins and scales. The average number of larvae per sweetfish was 4,333, compared with the average of 1,541 from the sea-run dace. It was found that the highest number of encysted larvae was found in the flesh of sweetfish, whereas it was encountered on the scales of sea-run dace. In the distribution pattern of the cysts, there was no relationship between the size of fish and the intensity of infection.

PURPOSE: To diagnose the coronary artery disease, it is necessary to have a thorough knowledge on coronary anatomy and normal variations. We performed a morphological study on normal variations of coronary artery in Korean adults. MATERIALS AND METHODS: 1012 cases of coronary angiography were analyzed with particular emphasis on the normal variation of three coronary arteries and their major branches, including origin of conus artery, sinus node artery and atrioventricular node artery and the variation in posterior descending artery and ramus medianus. RESULTS: We found right dominance in 895 cases(88.4%), left domainance in 44 cases(4.3%), and balanced dominance in 73 cases(7.2%). Conus artery branched from right coronary artery in 468 cases(47.6%) and originated in right coronary sinus close to the os of right coronary artery in 515 cases(52.4%). Sinus node artery originated from left circumflex artery in 551 cases(54.4%), from right coronary artery in 442 cases(43.7%), and from both coronary arteries in 19 cases(1.9%). Atrioventricular node artery originated from right coronary artery in 943 cases(93.4%), from left circumflex artery in 59 cases(5.8%), and two atriovenricular node arteries from both arteries in 8 cases(0.8%). Posterior descending artery had the normal pattern in 505 cases(58.6%) and some variation in 357 cases(41.4%). We found short left main coronary artery, less than 2--3 mm, making it hard to cannulate in 172 cases(17.0%). Ramus medianus was found in 165 cases(16.5%) with marginal distribution in 84 cases(8.4%), diagonal distribution in 80 cases(8.0%) and coursing interventricular sulcus as double left anterior descending artery in 1 case(0.1%). Left main coronary artery gave off 4 branches in 8 cases(0.8%). Myocardial bridging was found in only 3 cases(0.3%). CONCLUSION: This study could provide basic morphological data on anatomy and normal variations of coronary arteries in Korean adults.

Recently many studies have shown the usefulness of computed tomogram in diagnosing abdominal mass when clinical and conventional radiologic examinations fail to reveal the nature of abdominal mass or the cause of abdominal distension. To evaluate the usefulness of CT in diagnosing neuroblastoma, we retrospectively analyzed computed tomographic findings of 16 neuroblastoma patients, who pathologically proved in Yeungnam University Hospital from 1986 to 1995. The age range of the patients studied were from 8months to 18years. The most frequent sith of origin was adrenal gland and the next was retroperitioneum. The presenting symptoms were palpable mass, abdominal distension, and abdominal pain.- The viewpoints of this analysis were tumoral calcifications, midline cross, shape, margin, internal structure, contrast enhancement patterns, major vessel involvement, and lymph node involvement. ':haracteristic CT findings were 'as follows: Fine dense curvillinear calcification within the tumor(56%), midline cross(50%), lobulation(75%), well-circumscribed margin(56%), cystic degeneration(56%), heterogeneous contrast enhancement(690/o), encasement of major vessels such as aorta, IVC and celiac trunk(50%), and paraaortic lymphadenopathy(87%). We conclude that these CT findings were very common and could be helpful in diagnosting and differentiation neuroblastoma in infant and children.
