Aneurysmal bone cyst is an uncommon tumor-like lesion of the bone, containing distended channels or cavities filled with blood. This case, a eighteen years old female, complained of pain and swelling in the right lateral aspect of thigh. Roentgenograms showed a ballooned-out distension of the shaft of the femur, eccentric buldging of the cortex and soap-bubble appearance of interior of the lesion. The case was treated with radical curettage and autogenous bone graft with bone chips which were taken from the iliac wing. Pathological examination grossly and microscopically revealed an aneurysmal bone cyst. Patient made an uneventful recovery, and 11 months later she had no complaints and no evidence of recurrence.

We reviewed 90 cases of popliteal cyst in 88 patients, managed at Department of Orthopedic Surgery, Severance Hospital from January 1976 to June 1985 and the following results were obtained. 1. The average age of the 88 patients was 42 years. There were 23 males and 65 females. Of the all patients, 47 were occured in right side and 39 the left. Two patients were both sides. 2. Of the all cysts, 62 were found to be bursa between the semimembranosus and the medial head of the gastrocnemius muscles(68.8%). 3. Associated adnormalities of the knee joint were apparent in 29(33%) and the most common abnormalities were osteoarthritis. 3. Associated adnormalities of the knee joint were apparent in 29(33%) and the most common abnormalities were osteoarthritis. 4. Communication of the cyst with the joint was apparent in 44 cases(49%). 5. Twelve patients were recurred and associated abnormality of the knee joint was osteoarthritis. Three patients were children and they had no abnormality of the knee joint. 6. Recurrence after primary operation was rare when the stalk of the cyst had been opened.

Eleven cases of the free vascularized bone graft have been performed in the Department of Orthopaedic Surgery, Yonsei University Hospital during the period of 30.9 months from February 1981 to December 1985. Follow up ranges from 8 to 62 months. The indication for the procedure was reconstruction of extensive bony defect after acute trauma in 3 cases, osteomyelitis in 3 cases, chronic nonunion 3 cases, bone tumor in one case and congenital pseudoarthrosis in one case. The results were obtained as follows; 1. To reconstruct the lower extremity the vascularzed bone graft has much more advantages than the other conventional method and the technique may be very useful in the management of certain difficult reconstructive problem of the lower extremity. 2. In the defects of bone and skin, even infected, composite bone and soft tissue transfer can be filled by one stage operation and made the infection heal more rapidly. 3. In children the vacularized fibular graft was hypertrophied and similar to thickness of tibia.

Coronary spasm may be induced by a variety of physiologic and pharmacologic stimuli but specific receptor blockade has not been consistently shown to prevent the attacks. Most patients with variant angina respond well to treatment with calcium antagonists and nitrates. A small proportion of patients are refractory to this therapy. We report a case of the patient with a 9-year-history of variant angina who has been refractory to high doses of calcium antagonists and nitrates. The repeated addition of clonidine was consistently effective in abolishing both symptoms and objective evidence of myocardial ischemia in this particular patient.

To clarify the mechanism of the protective effect of hemodialysis on lipid peroxidation in RBC membrane structures, the level of malondialdehyde (MDA) which is the lipid peroxidation product, and the activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase, and glutathione peroxidase (GSH-Px) were determined before and after hemodialysis in the RBCs from 20 patients with end stage renal disease (ESRD), and from 14 healthy subjects. Before dialysis, MDA levels in the RBCs from the patients with ESRD were higher than those from healthy controls. SOD and catalase activities in the RBCs were lower. After hemodialysis, MDA, SOD, and catalase in the RBCs from the patients with ESRD were normalized. These results indicate that hemodialysis treatment is helpful to protect the peroxidative darnage through normalizing the activities of antioxidant enzymes.

BACKGROUND AND OBJECTIVES: Cisplatin (CP), an antitumor agent widely used in the treatment of head and neck cancers, has side effects such as ototoxicity and nephrotoxicity. These side effects are closely related to oxidative stress. In the present study, we attempted to suppress CP-induced ototoxicity in rats by administering melatonin, an antioxidant. MATERIALS AND METHOD: Male Sprague-Dawley rats were divided into different groups and were treated as follows: 1) saline control, 2) CP (16 mg/kg, i.p.), 3) CP plus melatonin (10 mg/kg, i.p.). The rats were sacrificed at the 6th day after CP treatment. RESULTS: CP-treated rats showed increase in cochlear malondialdehyde, hydrogen peroxide, glutathione peroxidase and glutathione reductase levels, and the decrease in cochlear superoxide dismutase (SOD) and catalase levels. CP-treated rats showed markedly decreased in the number of stereocilia on the inner hair cells and mildly decreased in the number of outer hair cells in organ of Corti under the light and scanning electron microscopic examination. Light and electron microscopic findings, and cochlear hydrogen peroxide, malondialdehyde, SOD, catalase, glutathione peroxidase and glutathione reductase levels were restored in the rats injected with CP plus melatonin than those with CP alone. CONCLUSION: These results suggest that melatonin suppresses CP-induced ototoxicity via the suppression of the increased production of reactive oxygen species.
