Thoracoscopic sympathicotomy is effective in treating not only palmar hyperhidrosis, but, also in treating axillary hyperhidrosis. In previous studies in Korea, sympathicotomy was focused on combinations including the 2nd to 4th sympathetic chains (R2,3,4). Using a minimally invasive technique, the results of sympathicotomy of the 4th and 5th chains (R4,5) of five patients, from February to August, 2002, for axillary hyperhidrosis without osmidrosis, were reviewed. All patients had a successful operation, their profuse sweating ceased. Three patients suffered from some degree of compensatory sweating. Among the three patients, only one patient suffered from moderate compensatory sweating over his back and thighs. Thoracoscopic R4,5 sympathicotomy offers a very appealing method in the treatment for axillary hyperhidrosis in patients who have profuse axillary sweating.

It was expected that recombinant Aspergillus niger glucose oxidase could be expressed in Trichoderma reesei with stable activity. T. reesei CBHI promoter--CBHI ss. gene--A. niger glucose oxidase gene--T. reesei CBHI terminator--A. nidulans gpd promoter--E. coli Hygromycin B phosphotransferase gene--A. nidulans trpC terminator--pUC19 (pCBHGOD) vector was constructed in E. coli DH5alpha by PCR application and gene cloning methods. T. reesei QM9414 protoplast was transformed by T. reesei CBHI promoter-CBHI ss. Gene--A. niger glucose oxidase gene--T. reesei CBHI terminator-A. nidulans gpd promoter--E. coli Hygromycin B phosphotransferase gene--A. nidulans trpC terminator linear DNA fragment (CBHGOD fragment) that was made by digestion of pCBHGOD with Kpn I. T. reesei mutant clone with homologous recombinant A. niger glucose oxidase gene was selected by PCR method. Recombinant glucose oxidase was produced by mutant T. reesei strain under induction of wheat straw for 5 days. Recombinant glucose oxidase molecular mass was showed the same as native A. niger glucose oxidase standard from Sigma company by Western blot analysis. Recombinant glucose oxidase activity was 25u/mL in medium. The yield was 0.5 g/L in comparison with Sigma company glucose oxidase standard. There was no recombinant GOD degradation during Trichoderma reesei cultivation that was showed in Western blot analysis. Trichoderma reesei has capability to be a new recombinant host for Aspergillus niger GOD production.

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the world. NAFLD is a hepatic manifestation of insulin resistance, the core pathophysiology of diabetes. Multiple clinical studies show that diabetes increases the risk of liver disease progression and cirrhosis development in patients with NAFLD. Diabetes has causal associations with many different cancers, including hepatocellular carcinoma (HCC). More recent studies demonstrate that diabetes increases the risk of HCC in patients with underlying NAFLD cirrhosis, confirming the direct hepatocarcinogenic effect of diabetes among cirrhosis patients. Diabetes promotes hepatocarcinogenesis via the activation of inflammatory cascades producing reactive oxygen species and proinflammatory cytokines, leading to genomic instability, cellular proliferation, and inhibition of apoptosis. Given the global increase in the burden of NAFLD and HCC, high-risk patients such as older diabetic individuals should be carefully monitored for HCC development. Future larger studies should explore whether the effect of diabetes on HCC risk in NAFLD cirrhosis is modifiable by the type of antidiabetic medication and the effectiveness of diabetes control.

Purpose: To analyze the cytokines that appear after a spinal cord injury in rats and to determine the agonists that regulate apoptosis. Materials and Methods: Sixty female Sprague-Dawley rats were anesthetized, and a laminectomy was performed at the 9th thoracic vertebra. The spinal cord injury was induced by dropping a 10 gm weight at a height of 20 mm. The subjects were divided into 5 groups. Group I was administered aminoguanidine, group II was administered GM-CSF, group III was administered riluzole, group IV was administered erythropoietin, and group V was administered methylprednisolone. A control group was administered normal saline. The results were assessed using the Tarlov motor grading method. In 1, 3, 5 and 7 days after the spinal cord injury, the rats were sacrificed and evaluated using the syringomyelic cavity size. Immunohistochemical staining for e-NOS and RT-PCR for XIAP were also performed. Results: Groups I, III, and V showed significantly different results in terms of the motor recovery and inhibition of increase in the syringomyelic cavity compared with the other groups (p<0.05). The e-NOS activity was observed in groups I, III, and V. The other groups showed almost no e-NOS activity. On the RT-PCR, groups I, III, and V showed significantly different results in terms of XIAP expression with time compared with the other groups. Conclusion: Steroids, NOS inhibitors and sodium channel inhibitors appear to be important factors for regulating apoptosis in the early stage of a spinal cord injury. Further study will be needed to develop new pharmaceuticals with synergic effects on spinal cord injuries.

BACKGROUND: Worldwide, approximately 2% of new cancers are of the brain. Five-year survival rates among brain cancer patients have been reported as a little over a third. Differences in clinical outcomes between brain tumor patients of different races remain poorly understood. METHODS: A retrospective chart review was performed on brain tumor resection patients≥18 years old. Demographics, treatment variables, and survival outcomes were collected. Primary outcomes were length of stay, recurrence rate, progression-free survival (PFS), and overall survival (OS). RESULTS: A total of 452 patients were included in analysis. Females and males had nearly a 1:1 ratio (n=242 and n=220, respectively). Mean age was 54.8 years (SD: 14.5 range: 18–90). Females composed 69% (n=48) of Asian patients; males constituted 31% (n=22). Mean age of the Asian patients was 55.9 years (SD: 14.6 range: 26–89). Asian-only cohort tumor pathologies included glioblastoma (GBM) (n=14), high-grade glioma (n=7), low-grade glioma (n=4), meningioma (n=38), and metastases (n=7). Of the 185 meningioma patients, non-Asian patients comprised 79% of the group (n=146). Of the 65 GBM patients in total, non-Asian patients made up 89% of the GBM cohort (n=58). There were no statistically significant differences between these groups of both cohorts in recurrence (p=0.1580 and p=0.6294, respectively), PFS (p=0.9662 and p=0.4048, respectively), or OS (p=0.3711 and p=0.8183, respectively). CONCLUSION: Studies evaluating the survival between patients of different racial backgrounds against several tumor varieties are rare. Patients of certain racial backgrounds may need additional consideration when being attended to despite the same mutational composition as their counterparts. Repeated studies using national databases may yield more conclusive results.

INTRODUCTION: This study examined the effect of a conservative neck dissection in patients with head and neck cancer. MATERIALS AND METHODS: A total of 24 patients, who underwent a conservative neck dissection for the treatment of oral cancer from January 2002 to December 2007, were included. All procedures were performed by one oral and maxillofacial surgeon. The mean age was 58.2 years (range, 19 to 79 years). The medical recordings, pathologic findings, and radiographic findings were evaluated. The mean follow up period was 41.1 months (range, 4 to 88 months). RESULTS: 1. Oral cancer was more common in men than women with a 3:1 ratio. 2. Histopathologically, squamous cell carcinoma(83%) was the most prevalent oral cancer in this study. 3. The most common primary site was the tongue(6 cases, 25%) followed by the mouth floor (5 cases, 21%), buccal mucosa (3 cases, 13%), lower lip, mandible, palate (2 cases, respectively) and salivary gland, retromolar area, oropharynx, alveolus (1 case, each). 4. Three out of the 24 (13%) subjects had a recurrence at the primary sites. 5. Two out of 24 (8%) subjects had a distant metastasis. 6. All 24 patients survived and there were eleven patients who passed 5 years postoperatively. CONCLUSION: A conservative neck dissection is a reliable and effective method for controlling neck node metastases in patients with oral cancer of the N0 or N1 neck node without serious complications.
