PURPOSE: The purpose of this study was to identify the roles of empowerment and emotional intelligence in the relationship between job embeddedness and turnover intension among general hospital nurses. METHODS: The sample for this study consisted of 224 nurses from four general hospitals of less than 500 beds located in Seoul and Gyunggi Province. Data were analyzed using frequency, percentage, mean, standard deviation, t-test, ANOVA, Scheffe test, Pearson Correlation and Hierarchical Multiple Regression. RESULTS: It was found that: (a) Job embeddedness and emotional intelligence had negative effects on turnover intension; (b) Emotional intelligence moderated the relationship between job embeddedness and turnover intension, but empowerment did not. CONCLUSION: Findings indicate a need to reduce the degree of turnover by enhancing job embeddedness among general hospital nurses. Further research needs to be done to refine this study.

Pigmented lesions of palmar and plantar skin may cause diagnostic problems, because some features of benign lesions in these sites may raise the suspicion of melanoma if considered alone. Transepidermal elimlnation is a mechanism by which a substance is eliminated through the epidermis, and it is apt to be confused with a feature of melanoma that tumor cells are located at all layers of the epidermis. We report a case of transepidermal elimination of nevus cells in acral letiginous nevus which needs a differential dignosis of melanoma.

One of the complication during or after subclavian vein cannulation is intravascular catheter or wire embolization. Although some studies have reported safety of retaining foreign body embolization, and even death. The intravascular foreign body can be removed surgically or non-surgically. With improvement in instrument technology and technique, percutaneous retrieval of intravascular foreign bodies has become a relatively common procedure. Commonly used methods to remove intravascular foreign bodies are loop snare and basket technique. Sometimes biopy forcep can be used. We have experienced 2 cases of non-surgical removal of intravascular foreign bodies. One of the foreign bodies was 7cm wire fragment in right atrium(RA), the other was a 50cm guide wire. We used the standard loop snare technique for removal of 7cm wire fragment in RA and stone removal basket and 3.0mm ACS PTCA balloon to remove the 50cm short guide wire.

BACKGROUND: CSF can be leaked from the nose or ear due to fractures, tumors or surgical procedures in the skull base region, and the threat of impending meningitis necessitates early identification of it. Since 2-transferrin occurs practically in cerebrospinal fluid (CSF) and not in other body fluid, its detection from the rhinorrhea or otorrhea can be used for the diagnosis of CSF leakage. We carried out immunofixation-silver stain (IF-SS) method for detection of 2-transferrin in the CSF in order to know optimal identification condition of specific cerebrogenic marker. METHODS: The fresh CSF sample was collected by spinal tapping. 2-Transferrin was estimated by quantifying the total transferrin by nephelomertry (Behring, Germany). 2-Transferrin of CSF was identified by electrophoresis using Titan gel high resolution protein system (Beckman, USA), immunofixation with anti-human transferrin antibody (Dako, Denmark) and then stained with silver nitrate. Serial dilutions of CSF were performed to know the detection limit of 2-transferrin. To know the influence of blood mixing, tests for mixed specimen of serum and hemolysate in CSF were performed. To evaluate the specimen storage condition, tests for different temperature and storage time were performed . RESULTS: By IF-SS method, identification limit of 2-transferrin was 0.5 mg/dL in 1:4 diluted CSF with distilled water. And 2-transferrin could be detected in condition of mixing serum protein (7.5 g/dL) or hemoglobin (13 g/dL) with CSF up to 6 : 4. At various sample storage condition, such as 37degrees C, room temperature, and 4degrees C, band intensity decreased abruptly after 1 day, and it was not detected 5 days later. Mean while, in -20degrees C and -70degrees C, 2-transferin band was detected after 10 days. CONCLUSIONS: IF-SS method was sufficiently sensitive and specific for invalidation by blood contamination, and seems to be used as effective identification of 2-transferrin in the CSF without sample concentration, less diagnostic test for CSF leakage.

Congenital adrenal hyperplasia is inherited disorder of adrenal steroidogenesis. 21-hydroxylase deficiency is the most commone enzymatic defect and is divided into classic and late-onset or nonclassic forms. Both classic non-classic 21-hydrozylase deficiencies are inherited in a recessive manner as allelic variants. But it is rare that happened in twin infants. Chief complaints of affected twins in our case were ambiguous genitalia, hyperpigmentation and dehydrations. They were revealed into hyponatremia, hyperkalemia and increased amount of serum progesterone, 17-hydroxyprogesterone and urinary 17-ketosteroid excretion and were administered with DOCA, 9alpha-fluorohydrocortisone, hydrocortisone to control the electrolyte imbalance. And now, both of them are going to normal ratio of weight gain and body growth.

The present study was attempted to investigate and compare the antioxidant potency of several well-know flavonoids, antioxidant vitamin and commercially available popular beverages. The antioxidant potency was assessed by the effect on reducing oxidative DNA damage of human lymphocytes. Cellular oxidative DNA damage was measured by SCGE (single-cell gel electrophoresis), also known as comet assay. Lymphocytes were pre-treated for 30 minutes with wide ranges of doses of apigenin, kaempferol, luteolin, myricetin, rutin, quercetin, alpha-tocopherol (10,25,50,100,200,500,1000 micrometer) ,green tea extract or grape juice (10,50,100,250,500,1000 microgram/mL) followed by a H2O2(100 micrometer) treatment for 5 min as an oxidative stimulus. The physiological function of each antioxidant substance on oxidative DNA damage was analyzed as tail moment (tail length X percentage migrated DNA in tail) and expressed as relative DNA damage score after adjusting by the level of control treatment. Cells treated with H2O2 alone (positive control) had an extensive DNA damage compared with cells treated with phosphate buffered saline (PBS, negative control) or pre-treated with all the tested samples. Of all the six flavonoids, quercetin was the most potent antioxidant showing the lowest ED50 of 8.5 microgram/mL (concentration to produce 50% protection of relative DNA damage). The antoxidant potency of individual flavonoids were ranked as follows in a decreasing order; luteolin (18.4 microgram/mL), myricetin (19.0 microgram/mL) , rutin (22.2 microgram/mL) , apigenin (24,3 microgram/mL) , kaempferol (25.5 microgram/mL). The protective effect of alpha-tocopherol was substantially lower (highest ED50 value of 55.0 microgram/mL) than all the other flavonoids, while the protective effect was highest in green tea and grape juice with low ED5O value of 7.6 and 5.3, respectively. These results suggest that flavonoids, especially quercetin, and natural compounds from food product, green tea and grape juice, produced powerful anti-oxidative activities, even stronger than alpha-tocopherol. Taken together, supplementation of antioxidants to lymphocytes followed by oxidative stimulus inhibited damage to cellular DNA, supporting a protective effect against oxidative damage induced by reactive oxygen species.

The diagnosis of soft tissue osteochondroma should be considered when a well-defined osseous mass is located in the soft tissues. The differential diagnosis includes myositis ossificans, tumoral calcinosis, synovial chondromatosis, and soft tissue osteosarcoma, true osteochondroma which arises from bone. One case of soft tissue osteochondroma in the knee, a lesion of uncertain pathogenesis is reported.
