2 cases of Sprengel s deformity are presented as the first report of the country. This relatively uncommon congenital deformity was found not only scapula involved but also the adjacent spine and ribs as well. Even the patients are adult surgical intervention was tried because the disability was prominent with high scapula, and good range of the shoulder joint motions is restored.

Continued improvements in treatments of the thoracolumber spine have occured in the last several years. The operative treatment of choice currently is short segment fusion(instrumentation one level above to one level below the injury). The development of pedicle screw systems has brought short segment fusion into clinical reality from the posterior approach. We analysed the clinical results of 20 patients with unstable fracture and fracture-dislocation of thoracolumbar spine who were treated with the posterior transpedicular screw system. The mean fol- low-up was 18 month. Ll was the most common injury level and the bursting fracture was the most common fracure type by Denis classification. The mean preoperative sagital index was 21.5。 and improved 8.1。 postoperatively. The mean preoperative anterior and posterior height of the vertebral height were 56.9% and 88.8% and improved postoperatively 94.7 and 88.8 respectively. The mean preoperative neural canal impingement in neural defici: patient was 47.2% and was improved 30.65% postoperatively. The mean prooperative ASIA motor was 34.1 and improved 41.7 postoperatively. There was no metal failure. These data suggested that the posterior transpedicular screw fixation, transpedicle bone graft, decompression and posterolateral bone graft was able to porvide sufficient stability and to achieve the neurologic improvement.

Agrobacterium tumefaciens induces cancerous growths called crown galls at wound sites on dicotyledonous plants. A large plasmid called T1 plasmid is responsible for virulence. Upon tumor induction, part of the plasmid, termed T-DNA, becomes integrated into plant genome and its genetic sequences are expressed. These properties allow T1 plasmids to be used as gene vectors in plants. Several in vitro methods for the transfer of T1 plasmid into plant cell have been developed. One of them is the treatment of bacterial spheroplasts and plant protoplasts mixture with polyethylene glycol that is generally used as fusogen in cell-to-cell fusion. Several workers investigated the interaction of bacterial spheroplasts with plant protoplasts in the presence of polyethylene glycol and suggested that the interaction is not fusion but endocytosis. In this report we observed the interaction of Agrobacterium tumefaciens spheroplasts with Nicotiana tabacum protoplasts by electron microscope. Agrobacterium tumefaciens spheroplasts with Nicotiana tabacum protoplasts were prepared and mixed in the presence of polyethylene glycol and high pH-high Ca²⁺ buffer. Then the interaction of the spheroplasts with the protoplasts was examined by transmission electron microscope. After the treatment of polyethylene glycol the spheroplasts adhered to the surface of the protoplasts and then they were engulfed by the protoplasts. After the high pH-high Ca²⁺ buffer treatment the engulfed spheroplasts lost their cell integrity. No fusion process was observed. Thus all these observation suggest that the introduction process of Agrobacterium tumefaciens spheroplasts into Nicotiana tabacum protoplasts with the aid of polyethylene glycol is endocytosis.

Replacement of cardiac valves in the pediatric patients is infrequent compared with in adult for the treatment of diseased heart valve. Furthermore, uncertainties regarding the long term fate of prosthetic value and effects of a fixed-orifice walve in the growing children are the main concern in pedriatric patients. Between January 1974 and October 1979, in 10 children, 15years or younger, cardiac valves were replaced becasuse of congenital or acquired valvular heart diseases in the Department of Thoracic & Cardiovascular Surgery, Seoul National University Hospital. There were 8 mitral valves, one aortic valve and one mitral and aortic valve replaced. Indications for valve replacement were intractable congestive heart failure or apperently progressing cardiac symptoms and signs. Early postoperative death was noticed in one due to arrythmia, and late postoperative death in one due to cerebral thromboembolism after 9 months of double valve replacement. All Survlvors showed clinical improvement and good cardiac condition during postoperative and follow-up period till now.

Lymphomatous involvement of the gallbladder is rarely identified and manifests mostly as a local involvement of disseminated disease. There have been reported only about 20 primary malignant lymphomas of the gallbladder without involvement of other sites. A 63-year-old woman presented with jaundice, epigastric pain, and weight olss of two months duration. There was no systemic lymphadenopathy elsewhere. Abdominal computed tomograph revealed a focal thickening of the gallbladder wall. The removed gallbladder contained a well circumscribed, 5x3 cm-sized, slightly elevated firm area with accentuated mucosal papillary excrescences near the neck protion. The lesion involved whole thickness of the wall, and was made up of diffuse atypical lymphoid cell infiltrates of variable size accompanying plasmacytoid differentiation in areas. Some large tumor cells were pleomorphic and contained prominent nucleoli. To our knowledge, this is the first case of primary malignant lymphoma of the gallbladder in Korean literature.
