BACKGROUND: In vitro epidermal keratinocytes(EKs) culture systems are widely used in studying skin biology and differentiation. Recently a monolayer culture method of nail matrix cells(NMCs) has been developed. OBJECTIVE: This study was designed to establish a method of culture of NMCs and compared its characteristics with those of EKs. METHODS: Human NMCs were isolated and cultured in a defined medium. Phase contrast microscopic examination, growth rate and ketatin expression were evaluated. RESULTS: In in vitro monolayer culture, NMCs had a similar growth pattern and morphological features as EKs. The synthesis of hard keratins was detected. CONCLUSION: These observations suggest that the NMCs culture model may be useful for the study of nail properties and the effects of drugs.

PURPOSE: With advances in various treatment modalities, limb salvage surgery has been commonly used in osteosarcoma of extremities. An alternative method for skeletal reconstruction is reimplantation of the tumor bearing bone following extracorporeal irradiation (ECI). We report the long-term results of ECI autograft in aspect of the oncological and functional outcomes, and complications. MATERIALS AND METHODS: We retrospectively reviewed 31 osteosarcoma patients who underwent reconstruction with ECI between July 1995 and January 2006. There were 24 males and 7 females with a mean age of 24 (7-74 years) and a mean follow-up of 117 months (17-177 months). Twenty-five cases were reconstructed with ECI autograft, 6 cases with ECI autograft-prosthesis composite. The pathologic subtypes were conventional in 29 cases, periosteal in 1 case, and parosteal in 1 case. The most common location of tumor was distal femur (15 cases) followed by humerus (3), proximal fibula (3) and proximal tibia (3). Musculoskeletal Tumor Society (MSTS) score was used for functional evaluation. The overall survival rate, local recurrence, complications were analyzed. RESULTS: The overall survival rate was 80.6% and the disease-free survival rate was 64.5%. Five patients died of distant metastasis. One patient required above-knee amputation due to local recurrence. All of them, twenty-three complications occurred, which included nonunion in 7 cases, deep infection in 5 cases, joint instability in 4 cases, metal failure in 2 cases, Limb-length discrepancy (LLD) in 2 cases, periprosthetic fracture in 1 case, epiphyseal collapse in 1, local recurrence in 1 case. The mean MSTS functional score was 62.5%. CONCLUSION: Extracorporeal irradiated autograft can be achieved relatively good result in aspect of oncological and functional aspect, but is needed to be additional research about occurring many complications. The reconstruction with ECI after intercalary or fragmentary resection is effective reconstruction in aspect of oncological and functional result, complications.

Hypertrophic cardiomyopathy has been a well-known genetical transmitted disease entity with the advance of echocardiography. We have recently experienced a family with hypertrophic cardiomyopathy proved by noninvasive methods including chest x-ray,, electrocardiography and echocardiography. The propositus of this family was a 21 year-old solier who was admitted because of exertional dyspnea during military exercise. Both he and his sister had severely affected hearts with typical echocardiographic findings, asymmetrical septal hypertrophy(ASH) and systolic anterior motion of the anterior mitral leaflet(SAM). The clinical study is reported with the concerned literatures.

Since the first experimental nerve graft by Philipeaux and Vulpian in 1870, many successful graft have been reported by Bunnell, Boyes, Millesi, Sunderland and Seddon. Advances in microsurgery techniques prompted Millesi to introduce the concepts of interfascicular nerve grafting whereby groups of fascicles, and not whole nerve, are connected together. Hunt and Taylor described a free vasculized nerve graft with microvascular anastomoses and obtained rapid axonal advance and maturation of grafted nerve in a clinical case. It is true that a nerve graft should be inferior to an end-to-end nerve repair, because in the case of nerve grafting the axon have to cross two suture lines instead of one. On the other hand, nerve grafting is indicated whenever a significant gap is produced in a nerve as a result of injury. In a retrospective study of 46 patients, defect of the nerve with treated by nerve graft were analyzed from March, 1983 to January, 1993 and following results were obtained. 1. Nerve graft was useful method to repair nerve whenever a significant gap is produced in a nerve as a result of injury. 2. The sural nerve was used as a donor nerve and vasculized nerve graft can be useful. 3. Postoperative results of cases caused by electric burns were worse than others. 4. There were little significant value in the treatment results between epineural and perineural nerve graft. 5. Recovery of intrinsic function in median and ulnar nerve lesion above the elbow was poor and recovery of the intrinsic function in median nerve graft at the forearm level was better than level for lesion in the ulnar nerve at the same level.

Ultrasonography is most commonly utillized diagnostic tool in obstetric and gynecology for the evaluation ofpatient with a pelvic mass or pregancy. For it is characterized by no radiation hazard, noninvasive examinationand high diagnoastic accuracy. Also it affords an accurate assessment of the presence, size, location and internalconsistency of a pelvic mass. The recent availability and improved resolution of realtime scanning have afforded amore flexible and complete approach to evaluation of normal and abnormal structures in the pelvis. We analyzedultrasonographic findings in 154 pathologically proven cases of pelvic mass examined at Korea General hospitalfrom Jan. 1983 to Apr. 1984. The results were as follows; 1. The age distribution was from 12 years to 66 yearsand the majority of patients were between the ages of 21 and 50 yeasrs (91.4%). 2. The incidence of pelvic masswas 27.9% in uterine leiomyoma, 22.7% in ovarian cyst, 13.0% in addenomyosis and 8.4% in serous cystadenoma. 3. Mild to moderately echogenic nodular uterine enlargement with some cystic change(81.5%) of leiomyoma and multiplesmall vesicular pattern of intrauterine contents with uterine enlargement of Homole were the most common ultrasonographic findings. The location and type of leiomyoma were most common in the fundus and body (95.3%), and intramural myoma(53.5%). The most frequent finding of ovarian teratoma was cystic mass with echogenic focus(41.7%) but the echogenic appearance of the lesions was extremely variable. The ultrasonographic findings ofectopic pregnancy were cystic or complelx adnexal mass(80.0%), with or without fluid in cul-de-sac and deviationof uterus by adenxal mass. 4. Accuracy of ultrasonography in detemining the overall correct diagnosis of thepelvic masses compared with proven diagnosis was approximately 61.7%. The diagnostic accuracy was 90.7% inluterine leiomyoma, 100% in H-mole nad 80.0% in ectopic pregnancy.

Morphologically, kyphosis is devided into two groups, pure kyphosis and kyphoscoliosis, according to whether or not scoiiosis is combined. Or kyphosis can be devided into round kyphosis or angular kyphosis. The examples of round kyphosis are Scheuermanns kyphosis or ankylosing spondylitis. Acute angular kyphosis are of congenital kyphosis or old healed tuberculosis. The purpose of surgical correction of fixed kyphosis is to correct deformity as well as to prevent or to recover from paraplegia. The operation also improve respiratory and digestive function by diminishing compression of abdomen. However, the correction of this deformity is more dangerous in eliciting paraplegia than any other spinal deformity. In considering surgical correction of kyphosis we have to decide which approach is the best for that particular patient at that particular time. Usually majority of patient need combined anterior and posterior approach. The extent of fusion depends upon the flexibility of the kyphosis. Anterior fusion should encompass at least the rigid and inflexible portion of the kyphosis as determined by the hyperextension x-ray of the spine. Posterior fusion should encompass the full extent of the kyphosis. The purpose of this study is to report our results for surgical correction and to find the operative procedure which shows the best result. We hereby report surgically corrected 14 cases of fixed kyphosis who were hospitalized here from April 1988 to February 1995.

The Journal of the Korean Orthopaedic Association 1987;22(3):729-737
Since Luque introduced new posterior instrumentation by segmental sublaminar wiring for neuromuscular scoliosis in 1976, preliminary reports have been published regarding its use with Harrington rod or Luque rod for other types of scoliosis, traumatic lesions of the spine, and spondylolisthesis as well as for degenerative disorders and tumors. Its advantage includes rigid internal fixation which often obviates the requirement for postoperative immobilization and the significant correction of deformity. Disadvantages are longer operation time, increased blood loss and the risk of neurologic damage. Segmental spinal instrumentation was carried out using either Harrington rod or Luque rod in 30 cases of scoliosis; 16 in idiopathic scoliosis, 12 in paralytic scoliosis and 1 each in congenital scoliosis and neurofibromatosis, at the Department of Orthopedic Surgery, Seoul National University Hospital, for 3 years from January 1984 to December 1986, Twenty six cases had been followed for more than 1 year and following results were obtained. 1. In idiopathic scoliosis, average preoperative curve was 65.0 degrees and immediate postoperative curve was 27.9 degrees with 57.4% correction. There was 1.2 degrees loss of correction with an average follow-up of 19.5 months (14–28 months). 2. In papalytic scoliosis, average preoperative curve was 108.5 degrees and immediate postoperative curve was 55.5 degrees with 49.5% correction. There was little loss of correction with anaverage follow-up 24.5 months (13–38 months). 3. No neurological complication occurred as a result of sublaminar wiring. 4. Segmental spinal instrumentation is an effective method with an advantage of better correction, greater contouring of the spine to avoid flat back, and less external immobilization in the treatment of idiopathic or paralytic scoliosis without increased complication.

BACKGROUND AND PURPOSE: Radioopaque lesions are commonly seen in patients who received thoracic radiotherapy for various kinds of thoracic neoplasm, But therir exact diagnos are sometimes uncertain. PATIENTS AND METHODS: We examined simple chest radiograph and computed tomogram(CT) of 69 patients who received thoracic radiotherapy for lung cancer and were follow up at least 6 months in Yeungnam University Medical Center. RESULTS: Of the 69 patients. thirty-eight patients showed radioopaque lesions in their chest radiographs except radiation fibrosis; radiation pneumonitis was witnessed in 24 patients. infectious pneumonia in 8 patients, and recurrence in 6 patients. In radiateionpneumonitis patients, the pneumonitis occurred usually between 50 to 130 days after receiving radiation therapy, and interval between pneumonitis and fibrosis is 21 to 104 days. Simple chest radiographs of radiation pneumonitis(24 patients) represented ground glass opacities or consolidation in 4 cases(type I, 17%), reticular of reticulonodular opacities in 10 cases(type II, 42%), irregular patichy consolidations in 2 cases( type III, 8%), and consolidation with fibrosis in 8 cases(type IV, 33%), CT represent ground glass opacities or consolidation in 5 cases(type I, 29%), irregular nodular opacities in 3 cases(type II, 19%), irregular opacity beyond radiation fields in 3 cases(type III, 18%), and consolidation with fibrosis in 6 cased(typeIV, 35%). The CT of four patients who represented type II on simple chest radiographs reveal type I and III, and CT of two patients with clinical symptoms who had no abnormal finding on simple radiograph revealed type I. CONCLUSIONS: In conclusion, computed tomogram is superior to the simple radiograph when trying to understand the pathologic process of radiation pneumonitis and provide confidence in the diagnosis of radiation induced lung disease.

10.The Effect of Diabetes Mellitus on the Amount of Human Cataractous Lens Protein.
Journal of the Korean Ophthalmological Society 1986;27(4):587-590
We have quantified human cataractous lens protein in 10 diabetic patients and 10 non-diabetic patients by using a colorimetric method, to investigate the effect of diabetes mellitus on the amount of human cataractous lens prorein. Protein amount of the diabetic lens cortex(1.26 +/- 0.48mg/ml) was significantly smaller than that of the non-diabetic lens cortex(1.83 +/- 0.44mg/ml) (t=3.36, p<0.005). On the other hand, protein amount of the lens nucleus did not reveal a significant difference between the diabetic(3.06 +/- 0.61mg/ml) and the non-diabetic(3.08 +/- 0.96mg/ml) cataract patients.
