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.

CT scans of 23 patients with gallbladder carcinoma were retropectively reviewed to determine the incidence of lymphatic spread and to access the pattern of regional lymph node metastases. The lymphatic spread were noted in 74%(17/23). The involved patterns of regional lymph node metastases were nodes of porta hepatis 65%, portocaval nodes 41%, superior pancreaticoduodenal nodes 47%, posterior pancreaticoduodenal nodes 59%, nodes around the celiac trunk 35%, nodes around the superior mesenteric artery 29% and paraaortic nodes 35%. The findings suggested that the pattern of regional lumph node metastases in gallbladder carcinoma occurred along the normal lymphatic pathway of the gallbladder.

Sacrococcygeal chordoma is a rare malignant tumor which is believed to take its origin from remnants of the fetal notochord, and presents in the sacral hollow or occasionally posteriorly. The growth is leisurely and it is invasive rather than metastatic. In treatment, there is evidence that early diagnosis of sacrococcygeal chordoma followed by radical resection c palliative radiotherapy does provide the opportunity for cure. We have experienced two cases of sacrococcygeal chordoma, which were treated with one case of a complete surgical resection and the other case of only biopsy.

It is not unconimm that the monoclonal gammopathies occur in patients with demyelinating peripheral neuropathy. The IgM.-protein from those patients reacted with peripheral nerve myelin, which was first identified as the MAG (myelinassociated glycoprotein). In this study the authors tried to understand the pathogenetic mechanism of anti-MAG antibod by studying the expression of the anti MAG antibody in Epstein-Barr virus transformed lymphocytes of umbrical cord. The positive bands for anti-NMG antibody were found in 10 out of 320 sera of peripheral neuropathies by the thin layer chromatography of the glycolipids from bovine peripheral myelin. The positive anti-MAG expressions were found in 5 of 31 supernatant wells from EB virus transformed lymphocytes of umbrical cords, which tended to. Develop the antibody activity in the supernatants cultured more than ten days. The study indicates. In part that the anti-MAG antibody may be occurred by the autoimmune mechanism as the antibodies are expressed m the EB virus transformed lymphocytes which have never been exposed to foreign antigens so far However the automimune mechanism can be supported more by knowing the mcreased frequency of CD5 positive B cells in cases with high titer of anti-MAG antibodies.

A 61-year-old man was admitted to the emergency room complaining of a severe left exophthalmos caused by frontal and ethmoid sinus mucoceles that were visualized on a brain computerized tomogram. In addition, he had coexisting ankylosing spondylitis with a 20 year duration that resulted in total fixation of the cervical spine and progressive thoracic kyphosis. An unruptured anterior communicating artery aneurysm was found incidentally on the cerebral angiogram. We report that the anesthetic management for endoscopic sinus surgery of a frontal sinus mucocele in a patient with coexisting severe cervical spine ankylosing spondylitis and an unruptured cerebral aneurysm requires a detailed preoperative assessment of the airway, cardiac, pulmonary, and neurologic system. This case highlights the need for careful measures to avoid rupturing the cerebral aneurysm by the increased blood pressure induced by endotracheal intubation and the infiltration of an epinephrine-containing local anesthetic.

OBJECTIVE: The purpose of this study was to determine the efficacy of short segment fixation following postural reduction for the re-expansion and stabilization of unstable burst fractures in patients with osteoporosis. METHODS: Twenty patients underwent short segment fixation following postural reduction using a soft roll at the involved vertebra in cases of severely collapsed vertebrae of more than half their original height. All patients had unstable burst fracture with canal compromise, but their motor power was intact. The surgical procedure included postural reduction for 2 days and bone cement-augmented pedicle screw fixations at one level above, one level below and the fractured level itself. Imaging and clinical findings, including the level of the vertebra involved, vertebral height restoration, injected cement volume, local kyphosis, clinical outcome and complications were analyzed. RESULTS: The mean follow-up period was 15 months. The mean pain score (visual analogue scale) prior to surgery was 8.1, which decreased to 2.8 at 7 days after surgery. The kyphotic angle improved significantly from 21.6+/-5.8degrees before surgery to 5.2+/-3.7degrees after surgery. The fraction of the height of the vertebra increased from 35% and 40% to 70% in the anterior and middle portion. There were no signs of hardware pull-out, cement leakage into the spinal canal or aggravation of kyphotic deformities. CONCLUSION: In the management of unstable burst fracture in patients with severe osteoporosis, short segment pedicle screw fixation with bone cement augmentation following postural reduction can be used to reduce the total levels of pedicle screw fixation and to correct kyphotic deformities.

Allergic reaction to different fruits and vegetables has frequently been described, but an allergic reaction to mango fruit, including its sap, pericarp, stems and leaves, has rarely reported in the literature. Mango dermatitis, although not common, is the term for allergic contact dermatitis caused by mango. The Mango plant is found worldwide, and the plant shares chemical compounds that are similar to other substances of the Anacardiaceae plant. The substances uroshiol and cardol cause the allergic contact dermatitis. Any case of allergic contact dermatitis with eating mango fruit has not been reported in the Korean dermatologic literature. Here we report the first case of mango contact dermatitis in a 20-years-old female and this happened when she drank mango juice.

PURPOSE: To evaluate the efficacies and toxicities of concurrent chemoradiotherapy (CCRT), with or without intraluminal brachytherapy (ILB), using a retrospective analysis in esophageal carcinomas with respect to survival. MATERIALS AND METHODS: From April 1995 to July 2001, a total of 65 patients, diagnosed with an esophageal carcinoma, were treated by CCRT, with 21 also treated by ILB after CCRT. External radiotherapy was performed using 6 or 10 MV X-rays, with a dose range of 46.8~69.6 Gy (median; 59.4). The ILB was performed using high-dose-rate brachytherapy with Ir-192. The fractionation of ILB was 3 Gy by 4, or 5 Gy by 2 fractions. Cisplatin (75 mg/m2) was given on each first day of weeks 1, 5, 9 and 13, and 5-FU (1,000 mg/m2) as a continuous infusion for the first 4 days of each course. RESULTS: The median survival time of all patients was 15 months, and the 1, 2 and 3-year survival rates were 55.4, 29.2 and 20.7%, respectively. The 2-year survival rates of the patients with and without ILB were 33.3 and 27.3%, respectively (p=0.80). The 2-year survival rates of the patients with a complete, partial and no response were 44.1, 13.8 and 0%, respectively (p=0.02). The response to treatment was the only significant factor affecting the overall survival from a multivariate analysis. CONCLUSIONS: This study has shown that the survival outcomes of CCRT were much better than previous results with radiotherapy alone. However, the addition of ILB after CCRT showed no advantage over that of CCRT alone.

PURPOSE: It is accepted universally that correction of the cleft lip nasal deformity requires multiple stages of surgery. Following primary lip repair in infancy or early childhood, secondary surgery to improve the deformity of the lip and nose is frequently necessary. A suitable surgical procedure to correct the accompanying deformity, such as cleft palate and alveolus, must be carried out at an appropriate age. In developing countries, it is common for patients with cleft lip nasal deformity to present severe secondary deformities in adolescence, because of poor follow-up and inappropriate surgery. METHODS: The first patient was a 12 year old Mongolian boy. He presented prominent lip scar, short lip, wide columella, asymmetric nostril, palatal fistula, cleft alveolus, and velopharyngeal incompetence. He underwent cheilorhinoplasty, transpositional flap, alveoloplasty by iliac bone graft, and sphincter pharyngoplasty. On follow-up, a bilateral maxillary hypoplasia and a class III malocclusion developed. He underwent LeFort I osteotomy and maxillary advancement at the age of 16 years. The second patient was an 18 year old Eastern Russian girl. She presented with a deviated nose, right alar base depression, short lip, protrusion on vermilion, large palatal fistula, and severe VPI due to short palate. She underwent the combined procedure of cheilorhinoplasty, corrective rhinoplasty, tongue flap for palatal fistula, and superiorly based pharyngeal flap. And the tongue flap was detached at postoperative 3 weeks. RESULTS: The overall results have been extremely pleasing and satisfactory to patients. There were no postoperative complications. CONCLUSION: We discovered the one stage operation for radical correction was sufficient procedure to provide excellent clinical outcomes in patients with severe cleft lip nose deformity.
