BACKGROUND: In animal models of cerebral ischemic-reperfusion has been shown to have a beneficial effect. The object of this study is to compare the effect of pathologic findings between normotheimic and moderate hypothermic group. METHODS: We investigated the effect of moderate hypothermia induced 1 hour after transient(10 min) both carotid artery occlusion on the extent of ischemic-reperfusion cell damage in Mongolian Gerbil model. The terminal deoxyribonucleotidyl transferase (TdT) -mediated biotin-16-dUTP nick-end labelling(TUNEL staning) are used to detect apoptosis. RESULTS: 1. We suggest that Core body temperature is down to moderate hypothermia(30-32degrees C) beyond 10 minite by selective bain cooling method in Mongolian Gerbil model. 2. By light microscopy, ischemic-reperfusion damage were detected in the hippocampal CA1 pyramidal layer on the 3 day after transient ischemic insult, which showed chrosomal condensation and cytoplasmic eosinophilia. Ischemic-reperfusion cells were increased in the CA1 region on the 5 day. Apoptotic cells of the CA1 neurons seen by TUNEL staining than ischemic neurons seen by Hematoxylin-eosin staining were investigate 3 and 5 days after ischemic-reperfusion insult. CONCLUSION: We suggest that is not neuroprotective effects of Intraischemic(1 hour) moderate hypothermia in Gerbil brain global ischemic-reperfusion model.

To determine the effects of central nervous system (CNS) involvement in systemic Lupus erythematosus (SLE) on cerebrospinal fluid (CSF), CSF studies of 35 cases of SLE (22 cases with CNS involvement and 13 cases without CNS involvement) were analyzed and compared with 20 normal CSF studies. The mean values of several CSF parameters were significantly changed in the group of SLE with CNS involvement (increased protein, white blood cell (WBC) counts and pressure, and decreased glucose contents), but not in the group of SLE without CNS involvement. In 22 case of SLE with CNS involvement, 10 cases (45.5%) were more than 4 WBC's in CSF, 12 cases (54.6%) more than 40 mg/dl of CSF protein and 8 cases (36.4%) less than 40 mg/dl of CSF glucose. CSF pressure was increased more than 200 mm CSF in 41.2%. On the other hand, in 13 cases of SLE without CNS involvement, the CSF studies were almost normal except 4 cases (30.8%) of more than 40 mg/dl in CSF protein.

The biocompatibility of the titanium has been estabilished through various experimental studies such as cell culture toxicity test, pyrogen test, mutagen test and others. In order to confirm biocompatibility after fabrication of titanium and to clarify the difference between the bone reaction after insertion of the lathed titanium rods and the bone reaction after insertion of the finished and polished rods, both rods were implanted into the proximal femur of a rabbit. Histologic reactions in the bone were observed according to the ASTM standards at the intervals of 6 weeks, 12 weeks and 26 weeks after implantation. The result were as follows In 6 weeks after implantation of lathed titanium rods, inflammatory reactions, such as minimal degree infiltration of polymorphonuclear leukocytes and lymphocytes were observed in all cases. This was thought to be caused by surgical trauma. However, inflammatory cell infiltration was not seen after implantation of polished and finished rods in all cases. The cellular infiltration and the histologic reaction of the bone after implantation of lathed group were significantly more pronounced than those after implantation of the finished group. In 12 weekt after implantation of lathed rods, two of four cases revealed a minimal degree of cellular infiliration and histologic reaction seemed to be more pronounced in the lathed group, but they were not significant statistically.

PURPOSE: Pancreatic injury is rare in abdominal trauma patients (3%~12%). but it could result in significant morbidity and even mortality. Early and adequate decision making are very important in the management of patients with traumatic pancreatic injury. The purpose of this study was to assess the kinds of management and outcome through the review of our experience of pancreatic injury with multiple trauma. METHODS: We reviewed 17 patients with traumatic pancreas injury via electronic medical records from Jan. 2002 and April. 2011. We collected demographic findings; the type, location and grade of pancreas injury, the treatment modality, and patient's outcomes, such as complications, length of hospital stay (LOS), and mortality. RESULTS: Total 17 patients were reviewed, and man was 13 (88%). Traffic accident was the most common cause of injury. Pancreas neck was the most common injured site, and occured in 5 patients. Ductal injury was detected in 7 cases. Eleven patients were treated by surgical procedure, and in this group, 3 patients underwent the endoscopic retrograde pancreas drainage procedure coincidently. ERPD was tried in 8 patients, and failed in 2 patients. The major complications were post-traumatic fluid collection and abscess which accounted for 70% of all patients. The hospital stay was 35.9 days, and it was longer in patient with ductal injury (38.0+/-18.56 vs. 34.5+/-33.68 days). Only one patient was died due to septic shock associated with an uncontrolled retroperitoneal abscess. CONCLUSION: Early diagnosis is the most important factor to apply the adequate treatment option and to manage the traumatic pancreas injury. Aggressive treatment should be considered in patients with a post-operative abscess.

PURPOSE: Glucose uptake and glycolytic metabolism are enhanced in cancer cells, and increased expression of glucose transporter 1 (GLUT1) has also been reported. The aim of this study was to investigate GLUT1 expression in human breast tissues and invasive ductal carcinomas. METHODS: We used tissue microarrays consisting of normal breast tissue, ductal hyperplasia, ductal carcinoma in situ, invasive ductal carcinoma, and lymph node metastases. We examined GLUT1 expression in the microarrays by immunohistochemistry, reviewed the medical records and performed a clinicopathological analysis. RESULTS: Membranous GLUT1 expression was observed in normal and tumor cells. GLUT1 expression was higher in ductal carcinoma in situ, invasive ductal carcinoma, and lymph node metastasis than in normal tissue and ductal hyperplasia (p=0.002). Of 276 invasive ductal carcinomas, 106 (38.4%) showed GLUT1 expression. GLUT1 expression was correlated with higher histologic grade (p<0.001), larger tumor size (p=0.025), absence of estrogen receptor (p<0.001), absence of progesterone receptor (p<0.001), and triple-negative phenotype (p<0.001). In univariate survival analysis, patients with GLUT1 expression had poorer overall survival and disease-free survival (p=0.017 and p=0.021, respectively, log-rank test). In multivariate survival analysis with the Cox proportional hazards model, GLUT1 expression was an independent prognostic factor of poorer overall survival and disease-free survival (p=0.017 and p=0.019, respectively). CONCLUSION: GLUT1 expression seems to play an important role in malignant transformation, and the glycolytic phenotype in invasive ductal carcinoma may indicate aggressive biological behavior and a worse prognosis.

Sensory neuropathy is characterized by pure sensory dysfunction, ultimately evolving into areflexia and severe sensory ataxia in spite of the preservation of the other functions in the nervous system such as motor function. This disorder is known to be commonly found in cancer patients as a paraneoplastic syndrome, but nowadays many reports are made that sensory neuropathy is not merely related to malignancy but also with autoimmune disorders such as Sjogren's syndrome or polyclonal gammopathy, etc. Hence we report two patients who have been diagnosed as chronic idiopathic ataxic sensory neuropathy through electrophysiological and histopathological studies without any evidence of cancer or any other known cause.

BACKGROUND: Though caudal block is a relative simple technique, it has not been widely used in adults because of a high failure rate. We assumed that any tests to quantify the changes of sympathetic tone in the affected areas would be excellent indicators of successful block. We tested the usefulness of two candidates (pulse oximetry plethysmographic waveform amplitude measured at 5th toe and calf minus 5th toe skin temperature gradient) as indicators of successful caudal block. METHODS: In 45 adult patients undergoing anal surgery with caudal block, these two variables were simultaneously measured at 2-min intervals for 20 min. A two-fold increase in the plethysmographic waveform amplitude from baseline and skin temperature gradient of 0oC were predefined as test criteria of successful block. RESULTS: While the sensitivity, specificity, positive predictive value, and negative predictive value of the skin temperature gradient test were 45.9%, 100%, 100%, and 9.1%, those of the plethysmographic waveform test were 86.5%, 100%, 100%, and 28.6%. The plethysmographic waveform test showed a significantly higher discriminative capacity than the skin temperature gradient test (94.9% vs. 48.7%, P < 0.05) CONCLUSIONS: Unlike the skin temperature gradient test, the plethysmographic waveform test showed a considerably high validity in detecting successful block. Considering its simple and real time monitoring potentials together with a high failure rate of caudal block in adults, we cautiously recommend it as a supplemental diagnostic tool to predict successful block, especially when verbal communication with patient is difficult.
