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.

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.

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.

Amyloidosis is the definition for a group of diseases that have, in common, the infiltration of one or more tissues by an abnormal protein material-the amyloid substance, which is detected histologically by their green polarization color after Congo red staining. Despite increased interest on basic nature of amyloidosis by recent immunohistochemical or experimental study, the knowledge about the incidence and neurotoxic effect of cerebral amyloid or concomitant occurrence with brain tumor is still inchoate. We examined the incidence and clinico-pathologic characteristics of the patients with amyloid deposits in supratentorial meningiomas. Particularly about their neurotoxic effect to adjacent brain is considered one of the possible cause of seizure in 33 patients who underwent resection surgery for meningioma at the Keimyung University during the past three years. The pathological review and subgrouping by histologic type were done in all 33 specimens with sufficient size of paraffin block, defined by their morphology and polarization color after Congo red staining for diagnosis of amyloid deposits localized in the tumor. Immunohistochemical studies using monoclonal antibodies for amyloid-A protein(AA) and beta-amyloid(A beta) were evaluated to identify subtypes of amyloidosis. The rate of incidence of amyloid deposit in meningioma was 21%, i.e. seven out of thirty three cases. All laboratory findings and clinical studies did not suggest a systemic form. Seizure occurrence was one out of seven cases(14%), which was of no statistical significance. Immunohistochemical study for AA subtype was all negative, but showed all positive for A beta protein around the vessels. Recent reports has also demonstrated that Amyloid precusor protein(APP) and A beta is related in Alzheimer's disease, hereditary cerebral hemorrhage with amyloidosis-Dutch type(HCHWA-D) and amyloid angiopathy. Our research data indicates that the incidence of amyloid deposit is as high as 21% in supratentorial meningiomas. It seems that it is one of the possible cause of seizure. Nonsystemic microdeposits of amyloid and their subtype and it's relationship to neurotoxic effect in meningiomas remain to be confirmed by immunoelectron microscopic examination or immunohistochemical methods.

A Solitary Fibrous Tumor (Sft) Is A Rare Neoplasm Originated From The Pleura, But They Can Occur In A Variety Of Extrathoracic Regions. Although Many Cases Of Primary Sft Have Been Reported, There Are Extremely Rare Repots To Date Of A Malignant Sft In The Spine Or Skull. A 54-year-woman Visited Our Hospital Due To Low Back Pain And Both Leg Radiating Pain. Several Imaging Studies Including Magnetic Resonance Imaging And Computed Tomography Revealed Expansive Enhanced Lesions In The Occipital Bone, T8, S1-2, And Ilium, With Neural Tissue Compression. We Performed Surgical Resection Of The Tumor In Each Site, And Postoperative Radiosurgery And Chemotherapy Were Performed. However, After Six Months, Tumors Were Recurred And Metastasized In Multiple Regions Including Whole Spine And Lung. The Authors Report Here The First Case Of Patient With Malignant Sft Of Tandem Lesions In The Various Bony Structures, Including Skull, Thoracic Spine, And Sacral Spine, With A Rapid Recurrence And Metastasis. Although Malignant Sft Is Extremely Rare, It Should Be Considered In The Differential Diagnosis And Carful Follow-up Is Needed.

BACKGROUND: The causes of hemolytic disease of the newborn are discrepancies of ABO group, Rh(D) or other RBC antigens. The discrepancies of Rh subgroups except Rh(D) and K typing can be seen rarely. The clinical symptoms of those types are mild and most clinicians have no interest in them. However, there exist some serious cases that need exchange transfusion. For that, we detected Rh subgroup phenotyping and Kell typing in blood obtained from cord and pregnant women and the frequency of discrepancy. METHODS: We examined the cord and mother's blood collected from 317 pregnant women from May to November, 1997. Rh(D) typing was done using slide method with anti-D (Dade, USA), and other Rh subgroup phenotyping using column agglutination test on MicroTyping system with Rh-K gel card (DiaMed, Switzerland). Irregular antibody screening was done in the cases of discrepancy. RESLUTS: The most frequent phenotype of Rh subgroup was CDe (41.3%) and then CcDEe (39.3%), but the K typing showed 0%. 90 cases of 317 pair-samples (28.4%) showed discrepancies between pregnant women and their neonates. The most frequent type of Rh discrepancy was c+E (50%) and then C or E (11.1%). 62 cord samples which obtained from neonates of Kyungpook and Chonnam provinces showed discrepancies, were all negative in the irregular antibody screening test. CONCLUSIONS: Rh subgroup phenotyping and irregular antibody screening in cord blood by column agglutination test is thought to be helpful in early diagnosis and treatment of hemolytic disease of the newborn, as a sufficient amount of cord blood can be collected easily rather than neonatal blood.

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.
