Plain radrographs of thirty nine patients with giant cell tumor of long bone and CT scans of twenty patients among the thirty patients were reviewed retrospectively to evaluate the frequency and significance of sclerosis of the tumor margin. The sclerosis of the tumor margin was observed on plain radiographs in thirteen patients(33.3%) and they were located either on epiphyseal or on both epiphyseal or metaphyseal portion of the tumor. The authors concluded that the giant cell tumor should not be excluded from the differential entities eventhough the tumor has the marginal sclerosis.

A retrospective analysis of survival data of 52 cases with brain astrocytomas was presented. All patients received post-perative radiotherapy in the period of 1973~1983 at YUMC, Yonsei Cancer Center. There were 24 patients with Grade II, 12 patients with Grade III and 16 patients with Grade IV astrocytomas. Survival rates were analyzed according to histologic grade of malignancy, age, tumor location. radiation dose and extent of surgical tumor resection. 5 year actuarial survival for patients with Grade II astrocytomas was 32.9% ad Grade III was 42.9%. The 1 year and 2 year survival rate of Grade IV astrocytomas were 46.7% and 0%. Histologic grade of tumor was important prognostic factor in brain astrocytomas. Age and extent of surgical resection were significant prognostic factors in all grades of astrocytomas and tumor location and radiation dose were significant in Grade II astrocytomas.

The effect of Atenolol on the blood pressure were studied in 31 cases of essential hypertension and on the effect of plasma renin activity in 8 cases. There were 8 cases of male with age 49.5(42-70) and 23 cases of female with age 49(35-71) years. 27 cases of 31 cases were untreated hypertensive patients and 4 cases were refractory to hypotensive drugs of diuretics and vasodilators. The Atenolol 50mg once-daily was given to all patients orally for 3 weeks. The blood pressure, heart rate, ECG and symptoms were checked in one week interval. In 8 cases, the plasma renin activity was measured by Dainabot Kit before and after one week medication. The results were as follows: 1. In 27 cases of untreated hypertension, the control blood pressure was 182.9/11.4mmHg in average. The blood pressure decreased in average by 18.3/11mmHg in one week, 23.7/15.9mmHg in two week and 21.5/10.5mmHg in three week. The heart rate also decreased by 7.4/min. in one week, 14.9/min. in two week and 7.8/min. in three week. These data showed considerable reduction of blood pressure and heart rate with 50mg Atenolol once-daily. 2. The basal plasma renin activity after one week medication was reduced by 46% in 8 cases and this data showed considerable reduction regardless control level of basal plasma renin activity. 3. There were considerable blood pressure reduction by adding Atenolol 50mg once-daily to diuretics and vasodilator to which patient's blood pressures were refractory. 4. There was no orthostatic hypotension or serious side effect by Atenolol medication.

A retrospective analysis on the MRI findings of 24 pathologically contirmed craniopharyngiomas was performed with emphasis on signal intensity of cystic portion and its chemical components. Axial, coronal MR scans were ontained, and in six patients, post-contrast study was done with Gadopentetate Dimeglumine(Gd-DTPA). In 14 cystic portions were aspirated to correlate the amount of chemical components such as calcium, glucose, protein, cholesterol, lipid, and iron with the signal intensity GT scans were also performed in 20 patients. In eight cases, tumors extended to subfrontal, third ventricle, and retrosellar area the extensions were well demonstrated in sagittal and coronal images. The signal intensity of cystic lesions on T2WI were variable but tended to be higher in high protein and iron contents. Calcifications were present in 20 cases and out of these, MRI detected calcification as very low signal intensity or signal void on T1WI and T2WI in 12 cases. Multiplanar imaging of MRI was very useful for the evaluation of tumor extension and the signal intensity of the cystic lesion tended to be higher on T1WI when the contents had high protein or iron components.
