PURPOSE: To describe the characteristic CT findings of ameloblastomas in the mandibleand maxilla. MATERIALS AND METHODS: CT findings of 11 patients with ameloblastoma (9 cases in the mandible and 2 cases in the maxilla) proved by excisional biopsy were evaluated retrospectively with regard to the location, size, multilocularity, solid and cystic component, cortical destruction, soft tissue invasion, and contrast enhancement RESULTS: These were 8 multilculer expansile and I unicystic (developed in a dentigerous cyst) mandibler ameloblasftomas, and 2 unilocular maxillary ameloblasftomas. All cases showed inhomogenously enhancing solid component, nine of which were larger than cystic component. Nine cases, larger than 5 cm in diameter, revealed either a focal or extensive cortical destruction with various degree of invasion into the adjacent structures. One maxillary ameloblastoma contained a thick calcification along the margin of the lesion. CONCLUSION: Maxillomandibular ameloblastomas appeared as expansile lesion containing enhancing solid component relatively larger than cystic portion and having cortical destruction in large lesions(5cm>). Maxillary ameloblastomas were unilocular in appearance in spite of multilocularity in mandibular counterparts.

The etiology of nephrotic syndrome in unknown. The characterization were proteinuria, hypoalbuminemia, generalized edema and hyperlipidemia. To assess the recurrence factors in the nephrotic syncrome, we measured serum immunoglobulin (IgG, IgA, IgM), albumin, complement, cholesterol and the 24-hour total urine protein at the initial relapse of nephrotic syndrome. Each data of frequent and infrequent relapsed nephrotic syndrome were compared. In total 67 cases, 18 cases were frequent relapsers and 26 cases were infrequent relapsers and 23 cases were normal control without renal disease. The levels of IgG and albumin in frequent relapser were 304 mg/dl and 1.59 g/dl as compared with 440 mg/dl and 2.06 g/dl in infrequent relapsers. The levels of IgG and albumin were signifecantly lower in frequent relapser than infrequent relapsers (p<0.05). This study might be useful to predict that very low levels of IgG and albumin at the first relapse might be related to high risk chances of frequent relapse in children with nephorotic syncrome.

Various techniques for treatment of large bone defects have been reported, instead of using autogenous bone graft. The author have applied and explored for bone repair with polyglactin 910 mesh and fresh fascia late. Full thickness 8x8mm bone defects were made on the frontoparietal bone of rabbits and group 1 defect was covered with polyglactin 910 and group 2 defects with fresh fascia late, but group 3 and 4 were not covered. However the periosteum was left on group 4 but it was not left on group 3. Samples were taken from the operation site for clinical and histological examinations on 2, 4, 8 and 12 weeks after operation, repetitively. The results were as follows ; 1. On the group 1, where ployglactin 910 mesh had been placed, the defects taken in 2, 4 ,8, 12 weeks after operation disclosed osseous regeneration with newly formed bone but the thickness was much less than the original bone. 2. On the group 2, where fresh fascia rata had been placed, the defects taken in 2, 4, 8, 12 weeks after operation disclosed same pattern of group 1. 3. On the group 3 and 4, where membrane had not been placed, the majority of the defects consisted of connective tissue and muscles. 4. On the group 1, resorption of polyglactin 910 mesh was completed after 4 weeks, but on the group 2, the fascial rata still remained intact.

Intra-Arterial Digital Subtraction Angiography(IADSA) was performed in 128 patients during 13-month period. Weexperienced the same advantages of IADSA over conventional film-screen angiography:(1) significant reduction incontrast material dose: 1/3 of the dose of conventional angiography, (2) reduced film cost: 18% of the cost ofconventional technique, (3) decreased need for selective catherization,(4) shortened examination time, and (5)more ready detection of cnntrast material.

Holoprosencephaly is a rare and complex malformation affecting the cleavage of the developing forebrain and is usually associated with defects of the mid Face. We have experienced a case of holoprosencephaly, diagnosed prenatally by ultrasound examination at 31 weeks of pregnancy in a 31-year-old primigravida woman. This case is characterized by holoprosencephaly, cleft palate, cleft lip, left renal aplasia and right renal hypertrophy. The chromosomal study showed a deletion of the long arm of chromosome 7, 46, XX, del(7)(q32), We report with a terminal deletion of chromosome 7q associated with atypical clinical picture and holoprosencephaly.

A total 73 cases of primary malignant bone tumors was reviewed and analysed clinically at the department of orthopaedic surgery, Kosin medicsl center, Pusan, Kores for 11 years from January, 1975 to December, 1985. The results were obtained as follows ; l. In the 73 cases of primsry malignant bone tumors, osteogenic sarcoma was the most common primary malignant bone tumor (57%) and followed by chondrossrcoma (10%), multiple myeloma (8%). 2. Average survival times according to each primary malignant bone tumors was more than 3 years in chondrosarcoma, reticulum cell sarcoma, and synovial sarcoma, 28 months in osteogenic sarcoma, and 7 months in Ewings sarcoma. Ewings sarcoma had the worse prognosis and the slowly progressing tumors-chondrosarcoma, reticulum cell sarcoma and synovial sarcoma are needed long term follow up. 3. In osteogenic sarcoma, the prognosis was better when developed in their 3rd decsde than when developed in their 2nd decade. 4. There is a slight difference in average survival time on the location of the site, for example when tumor is located in the distal femur, the prognosis was worst. 5. There is no difference in the prognosis. The mode of treatment did not effect to their prognosis. 6. It was clear that the tumors which had not been responded to chemotherapy or radiation therapy had poorer prognosis. Chondrosarcoma, fibrosarcoma and synovisl sarcoma were considered as slowly progressed tumors, and so it may be benefit to the patients that chemotherapy and/or radiotherapy were prescribed.
