Discoid meniscus has been defined as a morphological anomaly, and several clinical classification has been proposed. Commonly used classification is Watanabes classification; complete, incomplete and Wrisberg ligament type discoid meniscus. It is a relatively more common disease of the knee in Korea and Japan than western countries. Eighty-one discoid meniscal tears which were operated arthroscopically between the period of June, 1991 and August, 1996 were reviewed retrospectively. The purpose of this study is to analyze the pattern of the tear and the extent of arthroscopic resection according to the arthroscopic classification of the discoid meniscus. Thirty-three cases were classified as complete and forty-five cases as incomplete and three cases were Wrisberg ligament type. The major pattern of the tear in the complete type lesions was horizon- tal(in twenty-three) and complex(in seven) tear. Of the knees that had an incomplete type lesion, longitudinal(in ten including six bucket-handle tear) and degenerative tear(in eight) were observed more frequently, and horizontal tear(in ten) less frequently than that of the complete type. The extent of arthroscopic resection of the discoid meniscus was related to the pattern of tear and type of the discoid meniscus. For the majority of the horizontal tear, arthroscopic partial meniscectomy (twentyeight of thirty-four) was performed, but arthroscopic subtotal and total meniscectomy was performed more frequently for longitudinal tear, complex tear, and Wrisberg ligament type.

Purpose: The diagnostic usefulness of fetal echocardiography in congenital heart disease is well known. One of the indications for fetal echocardiography is presence of extracardiac anomalies and such coexistent congenital heart disease may have important implications for obstetric and neonatal management. MATERIALS AND METHODS: 496 women with singleton pegnancies with amgenital anomalies that underwent penatal care and follow-up in Severance Hospital for 5 years from 1991 to 1995 were evaluated for the incidence of congenital heart disease. RESULTS: The incidence of congenital heart disease in fetuses with the associated extracardiac anomalies were as follows; central nervous system 6.9%(11/160), gastro-intestinal system 10.7%(8/75), genito-urinary sysem 4.7%(4/85), others 5.6%(4/72). Thirty-one of eighty-ane fetuses with congenital heart disease were found to have the associated extracardidac anomalies and ten of them chenoscenal abnormalities. CONCLUSION: We recommend that fetuses with congenital extracardiac anomalies sbould be checked for the presence of congenital heart disease and chmmosomal abnormalities, if needed.

Extensive laceration of the lung itself has relatively little attention as a threat to life compared with other intrathoracic organ injuries. The incidence of pulmonary laceration extensive enough to require thoracotomy is rare, but is higher than expected. The diagnosis of extensive pulmonary laceration may be difficult, but this injury should be suspected with attention and early thoracotomy can be carried out in indicated cases. Recently, thoracoscopy has assumed a major role in the management of a variety of surgical diseases of the chest. We experienced a case of extensive pulmonary laceration caused by nonpenetrating trauma, which underwent lobectomy by thoracoscopic surgery. A 21-year-old man who was injured in a motocycle accident was brought to Emergency Room from the scene by an ambulance, and complained of chest pain and dyspnea. A chest roentgenogram showed a hemothorax and fractures of the posterior ends of the right seventh, eighth, and ninth ribs. A chest tube was inserted. Thirteen hundred ml of blood was drained through the chest tube during the next one hour. Emergency right mini-thoracotomy revealed extensive laceration of the lower lobe extending to the pulmonary hilum. The lower lobe was the most badly torn. A lower lobectomy was done by video-assisted thoracic surgery (VATS). He complained less postoperative pain and the postoperative course was uneventful.

PURPOSE: The inhibitory effect of TGFbeta1 on survivals of L1210 and anticancer drug- resistant L1210 sublines was investigated and the gene expression of TGFbeta1 in these cells was examined. MATERIALS AND METHODS: The survivals of L1210, adriamycin-resistant(L1210AdR), vincristine-resistant(L1210VcR) or cisplatin-resistant(L1210Cis) cells were measured by MTT assay after treatment of TGFbeta1. Northern analysis was performed for TGFbeta1 gene expression in L1210, L1210AdR, L1210VcR or L1210Cis. RESULTS: There was no different survival ratio between two groups, control and TGFbeta1(10 ng/ml) treated groups in L1210 cells. However, the survival ratio of L1210AdR was 59% in TGFbeta1 treated group for 96 hours. The survival ratio of L1210VcR was 61% for 96 hours in TGFbeta1 treated group. The survival ratio of L1210Cis was 40% for 96 hours in TGFbeta1 treated group. Expressions of TGFbeta1 gene in drug-resistant sublines were significantly decreased than that of L1210 cells. CONCLUSION: Growth of anticancer drug-resistant L1210 sublines were inhibited by TGFbeta1 but not in L1210 cells. So, it is suggested that TGFbeta1 gene expression may have a part in anticancer drug-resistance.
