Atrial myxomas are uncommon, but surgical treatment offers a potential cure. Early diagnosis is essential so that tumors can be promptly removed in order to reduce morbidity or mortality from atrioventricular valve dysfunction and embolic complications. They are intracavitary tumors occurring within any of the cardiac chambers, but they have a predilection for the atria, particulary the left atrium. The development of noninvasive, echocardiogaphic technique has made it possible to screen large numbers of patients with atrial myxoma with ease and safty. Recently the development of diagnostic procedure and cardiac surgery increased the accuracy of diagnosis and the opportunity of successful ereatment. We report the two cases of left artial myxomas which were removed successfully by surgery.

The fracture of femoral neck, the unsolved fracture, is a msjor periphersl fracture of our skeleton, and for more than century its treatment and the results hsve been a matter of controversy and inquiry among surgeons, and although the results obtained today show improvement, they are not at all comparsble to those of other fractures. This study was performed to find the characteristics of femoral neck fractures in Korea and to give the direction of further treatment. Through the review of 30 articles reported on Journal of K.O.A., we suggest the followings are essential for further study. l. Epidemiologic study of femorsl neck fractures based on statistical data needs to be performed. 2. The study should be directed not only the frscture itself but also the prevention of the fracture via the study of osteoporosis. 3. The relationship of severity of fracture, time frorn trauma to treatment, and the result of treatment established by our own data is to be established.

Recent development in thepolymerase chain reaction (PCR) has brought an extraordinary opportunity for the rapid detection of M. tuberculosis in clinical specimens for the diagnosis of tuberculosis. Pneumoconiosis is a sort of pulmonary fibrosis consequent to inhalation of the respirable dust. The association between pulmonary tuberculosis and pneumoconiosis is well recognized. There is a 10-fold increase in the tuberculosis risk among the workers who have pneumoconiosis demonstrated by chest roentgenogram. The physicians managing the patients with pneumoconiosis have to maintain a high index of suspicion for the development of mycobacterial infection, since the diagnosis of tuberculosis is often difficult. Mycobacterium tuberculosis is a very slow growing organism and acid-fast bacillus (AFB) staining frequently shows false negative results, and therefore PCR would be a very rapid, easy and sensitive diagnostic method for the diagnosis of Mycobacterium tuberculosis in pneumoconiotic patients. To compare the PCR method with the conventional methods in diagnosing Mycobacterium tuberculosis in sputum, we used the sputa of 115 pneumoconiosis patients in Munkyeong Cheil Hospital. Of 32 pulmonary tuberculosis in the pneumoconiosis patients, 29 were PCR positive and were higher than 28, 20 positive by culture and AFB stain. Overall sensitivity, specificity, and which were 90.6, 91.5 % respectively for the PCR assay, 87.5, 100 % for the culture method ; 62.5, 98.7 % for the AFB stain. The PCR assay is a rapid, efficient, sensitive method which can detect M. tuberculosis directly in pneumoconiosis patients, and further study should be followed for the development of the easier method.

Genotoxic agents can induce various DNA lesions. DNA-Protein Crosslinks(DPCs) were known as the important DNA lesions which could impair gene expression because DPCs had a high probability of resisting repair and persisting through cell cycle. This repair resistance of DPCs could have biological significance but had not been evaluated clearly yet. Most of the studies that have evaluated the repair of DPCs only compared the extent of DPCs repair with other DNA lesions. We injected K2CrO4, a genotoxic agent, into Sprague-Dawley rats intraperitoneally(5mg/kg) and isolated blood lymphocytes 12 hours later. These lymphocytes were cultured in the mitogen added growth media and mitogen free media separately. The degree of the repair of DPCs was monitored for 4 days by the K-SDS assay. 4 day later, the amount of DPCs decreased by 4.6% in the mitogen added media but in creased by 10.9% in the mitogen free media. These results showed that DPCs induced by K2CrO4 were not repaired easily and the DPCs were biologically significant DNA lesions. We thought the decrease of DPCs in the mitogen added media was not due to the repair of DPCs, but from the increase of normal cell proliferation. Therefore, it is very important to consider the proliferation of normal cells when estimating the repair of DPCs.
