Pagets disease has been well known disease in western countries, but it is extremely rare in orient and no case has been reported in Korea yet. It is a chronic osseous disease affecting middle and late life, characterized by progressive skeletal deformities which consist of excessive resorption and abnormal regeneration. We experienced a case of Paget's disease in a 57-year old man with involvement of pelvis, femur and skull, and confirmed with open biopsy.

Two cases of synovial hemangioma have been experienced at the Department of Orthopedic surgery, Seoul National University Hospital. In the first case, synovial hemangioma about 1.5cm in diameter was found to be attached to the anterior aspect of the medial condyle of the left femur, which was excised completely with good follow-up result. In another case, cavernous hemangioma was observed diffusely invading tendon sheaths, lower one third of the tibia and also synovium of the ankle joint. Because of diffuse involvement, complete removal was not possible. After partial removal, a total 800 r Roentgen therapy was taken.

The acute anterior cruciate ligament injury is one of the most common ligament injury of the knee joint and there are many controversies in its treatment. Warren reported that the primary repair for the acute anterior cruciate ligament injuries was good, but some had opposite oppinions. Authors studied 23 patients of actue anterior cruciate ligament injury who were treated by primary repair from January, 1982 to December, 1984. The results were as followings: 1. The most common associated injury was MCL injury and posteromedial capsular injury(13 cases; 56.5%). 2. The most common detachment site of ACL was femoral attachment(11 cases; 47.8%) . 3. A medial Hocky Stick incision was found good in repairing the combined MCL and posteromedial capsular tear with ACL injury. 4. The results were good in 74% by Cincinnati score and in 87% by objective score. It is concluded that primary repair of the acute anterior cruciate ligament tear is cosidered successful.

There are many problems in treatment of intertrochanteric fractures due to osteoporosis and unstable pattern of fractures in old ages and they are different from those in young ages, for example, type of fracture, degree of osteoporosis, and general condition, ect. Anthors studied about the prognostic factors of 42 cases among 88 patients with intertrochanteric fractures, who were treated and followed up from Jan. 1982 to Dec. 1987. 1. The patients under 50 years old were mainly males(94.4%) and its chief cause of injury was traffic accident or fall down(72.2%). The cause of injury over 50 years old was slip down on ground(62.9%). 2. The osteoporosis was increased according to increased age of patients and then the unstable type of fracture was increased. In yaung patients, the unstable intertrochanteric fracture was rare despite of high violent injury. 3. The bone union of the follow-up patients was gained at average 13.8 weeks. 4. The sliding degree of lag screw was increased with unstable fracture and the incidence of metal protrusion into joint cavity was increased in the patients of eccentric fixation of lag screw into femoral head. 5. The all cases of complication were occured in osteoporotic patients over 50 years old and their causes were inadequate fixation of unstable fracture. 6. The most important factors in prognosis of intertrochanteric fractures are initial pattern of fractures, degree of osteoporosis and adequacy of reduction state(postop.).

There are several methods available to check bone masses. One of them is Singhs index which is singlest way with grading trabecular pattern of the proximal femur on anteroposterior X-ray film and the other is recently developed Dual Photon X-ray Absorptiometry which measures bone mineral contents. Some authors proclaim that Singh's index has low accuracy, objectiveness and reproducibility. So we studied for reliability of Singh's index and correlation between Singh's index and bone mineral contents measured by Dual Photon X-ray Absorptiometry in 65 patients. There are significant differences between 3 orthopedic surgeons in interpreting Singh's index (interpersonal difference). There are significant differences between first and second interpretation out of same surgeons (intrapersonal difference). There are significant differences interpretating among interpreted Singh's indices from films of different radiological exposures in the same radiograph. There are fair correlations(0.60-0.66) between Singhs index and bone mineral density. The Singh's index was overestimated in low bone mineral density with under-exposed radiograph, but Singh's index was under-estimated in high bone mineral density with over-exposed radiograph. Singh's index can be useful in clinical application by some modification.

PURPOSE: It has been reported that retinoic acid, one of the most popular agents for chemoprevention could inhibit the proliferation of many cancer cells including neuroblastoma and glioblastoma. However, there is increasing demand reaccessing its in vitro inhibitory effect on the tumor proliferation because of the poor results from recent clinical trials of retinoic acid in the malignant brain tumor. Retinoicacid ptomoted the diffferentiation and apoptosis of tumor cell so that its effect might be obvious in the pediatric brain tumor. Therefore we are going to confirm the effectiveness of retinoic acid to inhibit the proliferation of the tumor cells; glioblastoma and medulloblastoma in childhood. METHODS: Medulloblastoma cells were derived from the primary culture of the patient's specimen, and glioblastoma cells were cell lines of 373-MG and 87-MG. We estimated growth inhibition rate of each tumor cells using MTT assay in the concentration from 10 M to 10((-5))M of all-trans and 13-cis retinoic acid. RESULTS: 13-cis retinoic acid in the concentration of 10 6M inhibited cell growth rate 10-22% on the 4th day of incubation, 10% on the 7th day, and 0-12% on the 14th day in the concentration from 10((-6))M to 10((-5))M. All-trans retinoic acid inhibited cell growth rate less than 5% in the concentration less than 10((-5))M though the whole incubation period, but 42% on the 4th day, 37% on the 7th day, and 0% on the 14th day in the concentration of 10((-5))M. 13-cis retinoic acid inhibited cell growth rate 30% on the 4th day, 20% on the 7th and 14th day in the concentration between 10((-6))M and 10((-5))M. Alltrans retinoic acid inhibited cell growth rate less than 5% on the 4th and 7th day. Medulloblastoma cells showed growth inhibition more than 25% by all-trans and 13-cis retinoic acid in the concentration less than 10((-6))M. 13-cis retinoic acid showed 25% growth inhibition in the concentration above 10((-6))M, but all-trans retinoic acid showed 40% growht inhibition in the same concentration. CONCLUSION: We could not find the effect of retinoic acid in the glioblastoma cells due to variable responses of the tumor cell growth inhibition in the concentration of maximum tolerable dose. However, there ia a significant inhibitory effect of medulloblastoma cell proliferation both in the 13-cis and all-trans retinoic acid.

BACKGROUND: Procaine binds to DNA and reduces cisplatin nephrotoxicity, but the mechanism is poorly understood. We explored whether procaine amelioration of cisplatin nephrotoxicity was related to down-and/or up-regulation of inflammatory response gene tumor necrosis factor-alpha (TNF-alpha), oxidative stress indicator gene heme oxygenase-1 (HO-1) or cell cycle inhibitor gene p21. METHODS: Cisplatin and procaine were intraperitoneally injected to mice at a single dosage of 16 and 80 mg/kg, respectively. Renal evaluation was performed 72 hours after cisplatin administration. The expression of transcripts and proteins was analyzed using real time RT-PCR and Western blot, respectively. RESULTS: Procaine treatment moderately attenuated necrotic changes of renal proximal tubules and increases in BUN and creatinine concentration by cisplatin administration. Kidney platinum level between the cisplatin (cis) group and the cisplatin + procaine (CisPro) group was not different. Although the level of TNF-alpha mRNA increased 4-fold higher in the Cis group than in the control, this increase was not attenuated by procaine treatment. Gene expression of p21 and HO-1 was elevated 175 and 4-times higher in the Cis group than in the control, respectively. But their expression was no further elevated, rather significantly reduced in the CisPro group compared to the Cis group. Protein abundance of p21 and HO-1 was paralleled by their respective mRNA expression. CONCLUSIONS: Procaine amelioration of cisplatin nephrotoxicity is likely to be achieved through processes other than the regulation of TNF-alpha, HO-1 or p21 gene expression.
