CT was proved to be the most accurate diagnostic tool in the analysis of brain metastasis than any otherclassical methods. The authors studied CT findings of intracranial metastasis in 31 cases proven clinically andhistologically. The results were as follows; 1. Age distribution of the cases was 15 males and 16 females withpeak age of 6th decade in males and 4th decade in females. 2. Metastatic lesions were multiple in 18 cases andsingle in 13 cases. 3. The most common degree of edema was grade III, 43% of total metastatic foci. Markededematous low densities with relatively small nodular high densities in precontrast scan and variable contrastenhancement of the nodular densities were the most frequent CT findings. 4. No specific characterstics accordingto the primary cancer was noted. All four cases of choriocarcinoma showed hemorrhagic tendency.

We report a case of giant cell tumor of the tendon sheath involving the foot, in a 21-year-old female patient, who presented with an asymptomatic tumor on the dorsum of her right foot. Histopathologically the tumor is surrounded by thin fibrous connective tissue. The characteristic findings of the excised specimen revealed a typical mixture of abundunt round or polygonal histocyte-like cells with varying portions of spindle-shaped fibroblast-like cells and multinucleated giant cells. Variable amounts of hyalinized fibrous stromal tissue were also present. After excision, local recurrence has not been observed for 3 months.

Hereditary myopathy with early respiratory failure (HMERF) is characterized by early respiratory insufficiency which is inappropriate to the degree of limb muscle weakness. Recently, mutation in TTN gene was found in HMERF patients with the aid of gene sequencing. We describe the first case presenting with distal leg weakness and early respiratory failure confirmed by TTN gene mutation in Korea.

The present study was undertaken to investigate serum carboxyhemoglobin levels in smokers according to the amount of cigarrettes. many studies have shown definite and consistent relations between smoking and ischemic heart disease. The purpose of this study is to show that COHb levels can be used to discriminate between persons having certain ischemic heart disease and persons without these disease more accurately than is possible by using smoking history alone, and thus to suggest that this may be a good indicators of risk. The results of this study are as follow : 1) The incidence of ischemic heart disease in smoker is higher than that in non-smoker. 2) For a given COHb level there is no clear increasing trend in the population of affected subjects with increasing cigarette consumption and there is no significant change cigarette consumption under duration of 10 year's smoking history. 3) For a moderate and a heavy smoking categories there is a consistent effect of an increasing proportion of affected subjects as the COHb level rises and there is a significant change with COHb level under duration of 10 year's smoking history. 4) The same results are as over duration of 10 year's history. 5) There were no significant interaction between under duration of 10 year's smoking history and over duration of 10 year's smoking history. In conclusion, it seemed that cigarette smoking may play an important factor in development of ischemic heart disease by increasing serum carboxyhemoglobin level.

PURPOSE: The purpose of this study is to evaluate and compare the shear bond strength of the gingiva-colored composite resin and the tooth-colored composite resin to porcelain, metal and zirconia. MATERIALS AND METHODS: Sixty cylindrical specimens were fabricated and divided into the following 6 groups (Group 1-W: tooth-colored composite bonded to porcelain, Group 1-P: gingiva-colored composite bonded to porcelain, Group 2-W: tooth-colored composite bonded to base metal, Group 2-P: gingiva-colored composite bonded to base metal, Group 3-W: toothcolored composite bonded to zirconia, Group 3-P: gingiva-colored composite bonded to zirconia). The shear bond strength was measured with a universal testing machine after thermocycling and the failure mode was noted. All data were analyzed using the two-way analysis of variance test and the Bonferroni post-hoc test at a significance level of 0.05. RESULTS: The mean shear bond strength values in MPa were 12.39, 13.42, 8.78, 7.98, 4.64 and 3.74 for Group 1-W, 1-P, 2-W, 2-P, 3-W and 3-P, respectively. The difference between the two kinds of composite resin was not significant. The shear bond strength of Group 1 was the highest and that of Group 3 was the lowest. The differences among Group 1, 2 and 3 were all significant (P<.05). CONCLUSION: The shear bond strength of the gingiva-colored composite was not less than that of the tooth-colored composite. Thus, repairing or fabricating ceramic restorations using the gingiva-colored composite resin can be regarded as a practical method. Especially, the prognosis would be fine when applied on porcelain surfaces.

A case of extrapulmonary silicosis involving abdominal lymph nodes in a 62-year-old man is presented. The patient underwent subtotal gastrectomy and regional lymph nodes dissection for gastric adenocarcinoma of clinical stage III. On gross examination, two separate gastric adenocarcinomas and multiple enlarged lymph nodes mimicking metastatic lesion were noted. Microscopic examination of the enlaged lymph nodes revealed characteristic sclerohyaline silicotic nodules without metastatic adenocarcinoma. Chest roentgenogram showed diffusely scattered multiple tiny nodular lesions in the entire lung fields, particularly the posterior side of both upper lung fields. He had worked in a mine for 18 years and had been exposed to silica for 5 of those years. We report incidentally found, unusual case of extrapulmonary silicosis.
