Aspirin is one of the popular non -steroid anti -inflammatory drugs used in the management of pain. This study was performed to investigate the effects of aspirin on c -Fos expression in rat CNS after inducing somatic pain with formalin. Male S.D. rats were injected subcutaneously with 0.1 ml of 5% formalin in the plantar surface of right hindpaw. For experimental group, aspirin was administered orally before injection of formalin. Asprin -untreated group was utilized as the control group. Rats were sacrificed at 0.5, 1, 2, 6 and 24 hours after formalin injection. Rat brains were removed and sliced in rat brain matrix. Brain slices were coronally sectioned at interaural 5.70 ~6.70 mm. Serial sections were immunohisto-chemically reacted with polyclonal c -Fos antibody. The numbers of c -Fos protein immunoreactive neurons in the cingulate cortex, primary somatosensory area, and hippocampus were counted and analyzed statistically with Mann - Whitney U test. Results were as follows: 1. Higher numbers of c -Fos immunoreactive neurons were found in the cingulate cortex, primary somatosensory area and hippocampus. 2. Both aspirin -treated and -untreated groups, numbers of c -Fos immunoreactive neurons were significantly higher all time points than formalin -untreated group, which peacked at 2 hours. 3. The numbers of c -Fos immunoreactive neuron of the aspirin -treated group were less compared to the aspirin - untreated group at each time point. In conclusion, these results provide some basic knowledge in understanding the mechanism and control of formalin - induced somatic pain.

An increase in the dose of chemotherapy enhances the response of many experimental and clinical cancers, but the extent of chemotherapy dose escalation and repeated use is often limited by myelosuppression. The side effects of chemotherapy including bleeding and infection due to myelosuppression have resulted in delayed therapy and a reduction in the therapeutic dose, therefore it is necessary to overcome myelosuppression especially leukopenia in patients with gynecologic malignancies who recieved chemotherapy. This study is undertaken to investigate the clinical effects of rhG-CSF(recombinant human Granulocyte-colony stimulating factor) in 29 patients with gynecologic malignancy who recieved chemotherapy. It was given at a dose of 100 microgram bid/day subcutaneously until significantly increase of leukocyte count in leukopenic patient. The results showed, the rhG-CSF has significantly increased the number and function of leukocyte. The use of rhG-CSF was effective and useful to treat chemotherapy induced leukopenia and to accelerate the recovery from this complications.

Dyke-Davidoff-Masson syndrome is a rare disorder which developed hemiatrophy of brain, enlargement of ventricles and prominent pneumatization of petrous pyramid of the temporal bone. It manifests hemiparesis, varying type seizure, and mental retardation. We experienced two cases of Dyke-avidoff-Masson Syndrome, in a 6/12 year-old boy and a 1, 10/12 year-old girl who were admitted to our department of pediatrics, because of convulsion and hemiparesis The brain CT scan showed marked dilatation of lateral ventricle, prominent sylvian fissure and cortical sulci. So we report two cases of Dyke-Davidoff-Masson syndrome with review of literature.

PURPOSE: In a previous report, it took several days for white matter lesions to regress in hypoglycemic encephalopathy. We present a case of rapid diffusion-weighted image (DWI) changes in hypoglycemic encephalopathy. CASE REPORT: A 58-year-old male patient was found semi-comatous with the only abnormality in his laboratory tests showing hypoglycemia (44 mg/dL). After rapid correction of glucose level, immediate brain DWI showed bilateral subcortical white matter lesions. After about 5 hours, follow-up DWI showed resolved subcortical white matter lesions, with newly-appeared bilateral fronto-temporo-parietal cortical lesions. CONCLUSION: Both white matter and cortex involvement in hypoglycemic encephalopathy has been shown in several reports, but rapid regression of white matter changes in hypoglycemic encephalopathy has been rarely reported. It is important to know that MR imaging changes in hypoglycemic encephalopathy can be made as quick as just a few-hour-long.

The intracranial mycotic aneurysms are a rare complication in patients with infective endocarditis, and the management of the aneurysm is controversial. We presented a case of a 50-year-old woman who had infective endocarditis, complicated by an intracranial mycotic aneurysm of distal branch of the right anterior cerebral artery. Endovascular treatment using cyanoacrylate led to a successful result.

PURPOSE: This study was done to identify the relationship between self-efficacy and clinical skill competence of nursing students. METHOD: The participants in the study were 375 student nurses enrolled in 3rd & 4th year of a BSN program in Seoul and Gyeongi province, Korea. Data were collected from December 12, 2004 to November 30, 2005 using a structured questionnaire. Data were analyzed using SPSS 11.0 Win program. RESULTS: The average score for self-efficacy was 3.21+/-0.60, and for clinical skill competence 2.80+/-0.42. The self-efficacy score showed a significant difference according to student's year in college (t=2.494, p=0.013), and GPA score (t=4.299, p=0.000). The clinical skill competence score showed a significant difference according to year in college (t=5.351, p=0.000), GPA score (t=2.997, p=0.003) and satisfaction with course (F=5.214, p=0.006). There was a significant positive correlation between self-efficacy and clinical skill competence (r=0.224, p=0.000). CONCLUSION: These findings show that there is a need to develop strategies to improve self-efficacy for student nurses in Korea. And also, it is recommended that programs to improve clinical skill competence need to be included in nursing curricula.

The aim of this report is to show that treadmill running exercise under well-controlled conditions is to improve of regeneration in rat gastrocnemius muscles after physical injury. For this, rats were submitted to bouts of exercise on a treadmill up a 10 degrees decline for 60 min and gastrocnemius muscles were analysed at different exercise periods by immunohistochemistry in comparison with injured nonexercised muscles. Rats were used with guidelines for experimental procedures as set forth in the Declaration of Helsinki. We analysed the regenerative processes by detection of immunoreactivity for the two intermediate filaments, desmin and vimentin. Desmin and vimentin are specific components of the cytoskeleton of striated muscle fibers and of mononuclear cells of mesenchymal origin including myoblasts, respectively. We found that non-exercised rats had more desmin-and vimentin-positive myofibers than that of exercised rats at 9th, 16th, 23th, 30th day after physical injury. At 30th day, non-exercised rats had several desmin-and vimentinpositive myofibers, but exercised rats had numerous normal myofibers. These results show that exercise is able to improve regeneration processes in physical injured gastrocnemius muscles of rats.

Syndrome of inappropriate antidiutetic hormone(SIADH) secretion is the most common cause of hyponatremia in clinical medicine. Before diagnosis of the SIADH is made, other causes for a decreased diluting capacity and nonosmotic stimuli for AVP release need to be rule out. Disorders associated with SIADH can be divided into 4 major etiologic groups: malignancies, pulmonary diseases, central nervous disorders, and drugs. A 45-year-old woman was admitted due to maculopapular skin eruption and fever after taking medications for fever and myalgia. Generalized tonic clonic seizure was developed nine days later, and laboratory results showed marked hyponatremia. During the evaluation, treatment, and subsequent follow-up, the diagnosis of SIADH was confirmed, but the definitive cause was obscure. With fluid restriction, sodium replacement and demeclocycline therapy, she recovered completely 6 months later. We suggest that the SIADH might be related to drug-induced generalized maculopapular rash via menmgitis-like reaction in CSF as one of systemic adverse side effects to drugs rather than direct effect of related drugs.

INTRODUCTION: Distant metastases of mucoepidermoid carcinoma (MEC) are reported with the most common sites being the soft tissue of skin, lung, liver, and bone. We report here a very rare case of MEC with multiple metastases to the kidney, adrenal gland, skull and gluteus maximus muscle. CASE REPORT: A 63-year-old male patient presented with left-sided headache. Radiologic evaluations including CT and MRI showed ill-defined soft tissue lesion involving the left infratemporal fossa and left sphenoid sinus, and multiple enlarged lymph nodes in neck and mediastinum. PET-CT demonstrated multiple hypermetabolic lesions in and around the left kidney, left adrenal gland, right ischium, right gluteus maximus and skull base. These lesions were confirmed as MEC with multiple metastases through biopsy. DISCUSSION: Only one case of metastasis to the skull has been previously reported, and moreover, there has not been a case of metastatic MEC to the kidney, adrenal gland and gluteus maximus muscle so far in the medical literature. It is important to acknowledge the possibility of every unusual MEC metastases, since the presence of metastasis has statistically significant influence on the survival of MEC.

Glossopharyngeal neuralgia (GPN) is a rare condition characterized by paroxysms of lancinating pain in the regions of the tonsil, ear, larynx and tongue. The pain is typically triggered by activities such as swallowing, speaking or coughing. Fifty-seven years old female patient had suffered paroxysms of severe pain in the unilateral region of the glossopharyngeal innervation for several years, and long term drug therapy result in serious pancytopenia probably due to carbamazepine. The patient with idiopathic glossopharyngeal neuralgia received glossopharyngeal nerve block and her symptoms were relieved completely. Glossopharyngeal nerve block with alcohol was done by extraoral approach and satisfactory results were obtained.
