In this study the action of pancuronium given directly into the lateral ventricle on the mean blood pressure, heart rate, respiratory frequency and skeletal muscular contractility of the rabbit were investigated. Pancuronium, which a dose of 10ug/kg and 30kg/kg were given into the lateral ventricle of rabbit. 1) Intraventricular injection of 10ug/kg of pancuronium increased pulse rate, respiratory frequency and muscle contraction and the differences were not statiscally significant. 2) Intraventricular injection of 30ug/kg of pancuronium produced a gradual increase of respiratory frequency which began at 5 minutes after drug injection and continued over a half hour. The difference between control and experimental value was statistically significant (p<0.005) while pulse rate and muscular contractility were increased but not significant. 3) Mean blood pressure was not changed after intraventricular injection of the pancuronium.

Global aphasia without other focal neurologic lateralizing signs (GWLS) is an uncommon stroke syndrome. The pathogenesis of GWLS has been thought as the result of multiple cardioembolism. However, a few cases of GWLS with a single lesion have been reported. We report an unusual case of GWLS with a single left superior temporal infarction. A 73-year-old right handed man was admitted with receptive and expressive language impairment without other focal neurologic lateralizing signs. The patient's global aphasia symptom has being 4 weeks after symptom onset. Brain CT showed only one lesion of left superior temporal lobe. Our case notes that the multiple lesions of the speech area are not only necessary to produce GWLS, and it is not necessarily imply a double lesion or an embolic causes.

Obstructive sleep apnea (OSA), a common comorbidity in patients with stroke, has shown increasing prevalence over the past few decades. OSA is an important risk factor for stroke in addition to other well-known contributors, including hypertension, hyperlipidemia, atrial fibrillation, and diabetes mellitus. Moreover, OSA is an independent predictor of neurological outcomes and mortality. The pathological mechanisms underlying the association between OSA and stroke include autonomic dysfunction, hypertension, cardiac arrhythmia, dyslipidemia, impaired glucose tolerance, hypoxia, and inflammation. Continuous positive airway pressure (CPAP) therapy has proven clinical utility in improvement of neurological symptoms in patients with stroke. Findings from a CPAP withdrawal model have shown increased sympathetic activity in OSA with a consequent significant elevation in blood pressure, relevant cerebral hypoxia, and disturbed cardiac repolarization. In this review, we present an overview of the literature that describes an association between OSA and stroke in addition to the vascular risk factors, including hypertension, hyperlipidemia, atrial fibrillation, and diabetes mellitus. This study highlights the importance of early and accurate diagnosis and management of OSA for stroke prevention and care and will benefit physicians in clinical practice.

PURPOSE: The purpose of this study was to implement a software to visualize tumor and its surrounding fiber tracts simultaneously using diffusion tensor imaging and examine the feasibility of our software for investigating the influence of tumor on its surrounding fiber connectivity. MATERIALS AND METHODS: MR examination including T1-weigted and diffusion tensor images of a patient with brain tumor was performed on a 3.0 T MRI unit. We used the skull-striped brain and segmented tumor images for volume/surface rendering and anatomical information from contrast-enhanced T1-weighted images. Diffusion tensor images for the white matter fiber-tractography were acquired using a SE-EPI with a diffusion scheme of 25 directions. Fiber-tractography was performed using the streamline and tensorline methods. To correct a spatial mismatch between T1- weighted and diffusion tensor images, they were coregistered using a SPM. Our software was implemented under window-based PC system. RESULTS: We successfully implemented the integrated visualization of the fiber tracts with tube-like surfaces, cortical surface and the tumor with volume/surface renderings in a patient with brain tumor. CONCLUSION: Our result showed the feasibility of the integrated visualization of brain tumor and its surrounding fiber tracts. In addition, our implementation for integrated visualization can be utilized to navigate the brain for the quantitative analysis of fractional anisotropy to assess changes in the white matter tract integrity of edematic and peri-edematic regions in a number of tumor patients.

Rectal stricture is an occasional complication of abdominoperineal pull-through and low anterior resection of the rectum and irradiation injury. Although the causes and pathogenesis of this phenomenon are poorly understood, various techniques for stricture dilatation have been described. In this article, we present two cases of severe postoperative rectal stricture that were not amenable to conventional methods of dilation but were succesfully managed by transanal electroresection using endoscopic transurethral electroreectoscope.

PURPOSE: The aim of this study was to clarify the role of VEGF expression as an independent prognostic factor and to identify the patients at high risk for poor prognosis in stage IB cervical cancer. MATERIALS AND METHODS: A total of 118 patients with stage IB cervical cancer who had radical hysterectomy and pelvic lymph node dissection were included in the study. All known high risk factors of the patients were pathologically confirmed from the surgical specimen. Of the 118 patients, 88 patients were treated with postoperative radiotherapy and/or chemotherapy. VEGF expression was examined using immunohistochemistry in formalin-fixed, paraffin-embedded specimens of post-hysterectomy surgical materials. A semiquantitative analysis was made using a scoring system of 0, +, + +, and + + + for increasing intensity of stain. We classified the patients with scores from 0 to + + as low VEGF expression and the patients with a score of + + + as high VEGF expression. RESULTS: Of the 118 patients, 35 patients (29.7%) showed high VEGF expression. Strong correlations were found between the high VEGF expression and both deep stromal invasion (p=0.01) and the positive pelvic node (p=0.03). The 5-year overall and disease-free survival rates for all 118 patients were 95.5% and 93.8%. The 5-year overall (p=0.03) and disease-free survival (p<0.001) rates were 98.5% and 100% for low VEGF expression (0, +, and + +) and 85.5% and 79.7% for high VEGF expression, respectively. Pelvic and distant failures for low versus high VEGF expression were 1.2% versus 17.1%, (p=0.001) and 0% versus 14.3% (p<0.001), respectively. In a Cox multivariate analysis of survival, the high VEGF expression (p=0.02) and the bulky mass (p=0.02) were significant prognostic factors for overall survival. The high VEGF expression (p=0.002), and bulky mass (p=0.01) demonstrated as significant prognostic indicators for disease free survival. CONCLUSION: These results showed that VEGF expression was a highly significant predictor for pelvic and distant failure and the most significant prognostic factor of overall and disease free survival for the patients with stage IB cervix cancer treated with radical surgery. We strongly suggest that the immunohistochemistry for VEGF expression be performed in a routine clinical setting in order to identify the patients at high risk for poor prognosis in early stage cervical cancer. Furthermore, postoperative and/or chemotherapy did not reduce the pelvic failure and distant metastasis. To improve the cure rate for the patients with high VEGF expression in stage IB cervical cancer, antiangiogenic therapy including anti- VEGF Ab may be a new treatment option.
