The complications of Salter's innominate osteotomy in the treatment of congenital dislocation of the hip were avascular necrosis of the femoral head, hematoma, rotation of distal pelvic fragment, infection, fracture of femoral shaft and redislocation. Among them the causes of redislocation were technical failure, immobilization failure and absorption the bone graft, etc. We experienced a case of redislocation after open reduction and Salter s innominate osteotomy in congenital dislocation of the hip which was induced by a foreign body reaction to the suture material.

Thirteen Polio patients with leg length inequality were undergone Ilizarov lengthening procedures and have been followed along for an average two years(range, 1-3.8 years) after removal of the fixator. The age of patients(M:F=7:6) ranged from 18.0 to 32.2 years(average 26.4 years). The difference of true leg length averaged 2.1cm with the tibia being 3.3cm the femur, 1.2cm. The corticotomy was done at the proximal tibia and distal fibula in all case. The fixation period of the Ilizarov apparatus averaged 9.3 months. The length gain averaged 3.0cm for an average 3.8cm inequality. The healing index averaged 3.1mon/cm. Two out of thirteen patients complained of pain in the operated leg. The limping gait was improved in all patients except one. According to Paley's classification, there were ten cases of problems, one obstacle and four true complications. The problems were pin site infection controled with local antibiotics injection. There was one case of obstacle; tibial valgus deformity developed during lengthening. True complications included peroneal nerve injury, aggravation of preexsiting equinovalgus and claw toe deformities, aggravation of preexsiting valgus deformity of ankle and tibial valgus deformity. The complications execpt in one case of peroneal nerve palsy were solved out by the secondary procedures. In summery, the bone healing by distraction osteogenesis with the Ilizarov technique was relatively delayed in polio patients and it seems necessary to modify the technique to shorten the prolonged external fixation period.

Bovine growth hormone (bGH) gene was expressed in an insect spodoptera frugiperda cell line using a Baculovirus, Hyphantria cunea nuclear polyhedrosis virus (HcNPV). The bGH gene in pbGH plasmid was sequenced and amplified by PCR technique with two primers containing NcoI sites. The bGH gene consisted of 654 bp (217 amino acid residues), the 5'-untranslated region of the cloned bGH cDNA contains 56 bp, and the 3'-untranslated region contains 145 bp and two pallindromic regions. The amplified bGH gene DNA fragment (654 bp) was inserted into the NcoI site of the pHcEVII vector, which was named pHcbGH. The pHcbGH transfer vector DNA and the wild type HcNPV DNA were cotransfected into s. frugiperda cells to construct a recombinant virus. Eight recombinant viruses were selected and named HcbGH. One clone, HcbGH-4-1 showed largest plaque size, therefore the recombinant virus was further studied. The multiplication patters of the recombinant HcbGH-4-1 was similar to that of the wild type HcNPV. The bGH gene DNA in the HcbGH-4-1 recombinant was confirmed by Southern lot hybridization. The amount of the bGH (217 amino acid residues, 21 kDa) produced in S. frugiperda cells infected with the HcbGH-4-1 recombinant was approximately 5.5 ng per ml (106 cells) by radioimmunoassay.

Intraoral Vertical Ramus Osteotomy,along with Sagittal Split Ramus Osteotomy,is an popular surgical technique performed on mandibular prognathism. However Intraoral Vertical Ramus Osteotomy has been suspected for an initial mobilization at the healing phase of segment because it does not employ the rigid fixation between segments. To execute a study on the healing phase of seg-ment after Intraoral Vertical Ramus Osteotomy on the horizontal plane, 102 patients (204 parts) who were diagnosed mandibular prog-nathism and took Intraoral Vertical Ramus Osteotomy at the Yonsei University dental hospital were observed during the period of before operation, immediately postoperation, 1 month, 3 months, 6 months, and 12 months. The change in the width of segment and horizontal angle of proximal segment and condylar head on the Submentovertex Cephalogram taken from those patients represented following results. 1. The width of proximal and distal segment decreased with the lapse of time. It decreased into 84.5% between immediate postoperative and 6M and even continued to decrease till 12M. 2. The horizontal angle of the proximal segment did medial rotation according as the lapse of time and rigorously continued till 3M.The rotation angle of condylar head indicated its tendency of recurrence to the original position but the entire recurrence was not allowed. The bigger an initial angle was, the higher was the tendency of recurrence after the operation while the rotation angle remained still bigger. 3. After grouping into group 1, group 2,and group 3 based on the extent of the variation of rotation angle of condylar head at immediate postoperative, the variation of rotation angle was measures in each group. The result presented that the initial rotation angle of condylar head had correlation with that of proximal segment but had no relation with the extent of setback of the mandible. However a quantitative analysis alone is not a sufficient method for analyzing the healing phase of segment on the horizontal plane.Therefore a multilateral analysis using 3 dimensional data such as CT is recommendable for the future study.

PURPOSE: To evaluate the early clinical results of lumbar microdiscectomy using minimally invasive tubular retractor (METRx-MD system, Medtronic Sofamor Danek, Memphis, TN), and to validate the merits of minimally invasive spinal surgery. MATERIALS AND METHODS: From April, 2003 to April 2004 we retrospectively studied a consecutive series of 45 patients who underwent lumbar microdiscectomy using minimally invasive tubular retractor. In all cases, minimally invasive approach using the tubular retractor were performed with a 2 cm sized paramedian incision. The following data were collected: clinical outcomes, operative time, intraoperative blood loss, need for blood replacement, time needed before ambulation, length of hospital stay, and complications. The clinical outcomes were assessed by the modified MacNab criteria. RESULTS: Minimally invasive tubular microdiscectomy was performed in 45 patients over a 12-month period with an average follow-up of approximately 8 months. The clinical outcomes assessed by MacNab criteria were excellent in 33 patients (73%), good in 10 patients (22%). The average operative time was 63 minutes (range, 35 to 95 minutes). The average blood loss was 62 mL (range, 50 to 110 mL). None of the patients needed blood replacement. With the exception of 2 patients, all patients could walk at the day of surgery. The average hospital stay was 2.3 days. None of the patients had dural tear, wound problem, or other complications. CONCLUSION: Lumbar microdiscectomy using tubular retractor can offer a useful modality for the treatment of lumbar herniated disc with the merits of minimally invasive spinal surgery. Further long-term, randomized, prospective investigations are needed to fully evaluate the impact of this technique.

Malformations of umbilicus are a feature of many dysmorphic syndromes and the measurement of periumbilical skin length should be considered as the basic step in the description of the umbilical malformations. So, we measured the periumbilical skin length in the 103 normal neonates and obtained the following results. 1) The means (+SD) of the periumbilical skin length were the 11.7mm (+3.0) in the cranial site and the 8.2mm (+2.5) in the caudal site, and the cranial length was 3.5mm longer than the caudal length. 2) No difference was observed between the male and female groups in the periumbilical skin length. 3) Age was the only statistically significant variable associated with the periumbilical skin length and it was observed that the periumbilical skin length decreased according to the advance of age (hour).

Journal of the Korean Surgical Society 2000;59(4):532-538
PURPOSE: Intestinal atresia is a well-recognized cause of bowel obstruction in the newborn. The management of neonates with intestinal atresia has improved in recent decades due to refinements in neonatal intensive care, operative techniques, use of total parenteral nutrition (TPN), and neonatal anesthesia. More recently, the survival rate has risen rapidly up to 90%. METHODS: Twenty-five (25) cases of intestinal atresia were encountered at Kwangju-Christian Hospital between January 1985 and December 1998. We reviewed sex, gestational age, body weight, clinical manifestations, associated ano malies, causes, interval to operation, preoperative complications, operative methods, and postoperative complications. RESULTS: Sites involved were the duodenum (n=10; 40%), the jejunum (n=5; 20%), and the ileum (n=10; 40%). The sex distribution was male predominant (1.8:1). The overall survival rate in our hospital was 76%. CONCLUSION: Refinements in neonatal intensive care and perioperative management were important in decreasing postoperative mortality.

10.Impression Cytology of Herpetic Simplex Keratitis in Rabbits.
Korean Journal of Ophthalmology 2005;19(2):96-100
PURPOSE: To use impression cytology to examine the structural changes in corneal epithelial cells infected with the herpes simplex virus in rabbit eyes. METHODS: Corneal surfaces of 7 rabbits were scratched using a 25-gauge needle. Herpes simplex virus (type 1, Kos strain) was inoculated to the injured cornea. As the corneal diseases were observed using slit lamp biomicroscopy, impression cytology was performed for 18 days after inoculation. Specimens were stained with hematoxylin-eosin and examined using optical microscopy. RESULTS: Corneal lesions consisted mainly of round epithelial cells, inflammatory cells, ballooning cells, multinucleated giant cells, and various inclusion bodies. Over time, the corneal epithelial cells peeled away as a result of corneal edema in the corneal lesions. Dendritic lesions were also observed. In the recovery phase, the number of detached cells and infiltrated inflammatory cells decreased. CONCLUSIONS: It was presumed that dendritic lesions might have been formed at the scratched cornea region, thereby aggravating the epithelial cells falling off as a result of the infiltration of inflammatory cells. These cytopathologic effects occur in experimental herpes simplex keratitis.
