Background: This study was aimed to identify the level of awareness and compliance on the nosocomial infection control among clinical nurses. Methods: Data was collected from Sept. 15 to Oct. 10, 2001 and obtained from the nurses working at six general hospitals in Daegu city and Kyungpook province. Five hundred sixteen nurses were answered to the 36 item questionnaire which was composed of the hand washing(5 items), the management of sterile article(7 items), the management of contaminated article(8 Items), the administration of medication(8 items) and the environment management(8 items). Results: The mean score of the awareness about the infection control was 3.59/4. In sub-sections, the mean score of the administration of medication was 3.66, the hand washing was 3.65, the environmental management was 3.60, the sterile article management was 3.57, and the contaminated article management was 3.48. The mean score of the compliance about the infection control was 0.78/1. In sub-sections, the mean score of the administration of medication was 0.88, the sterile article management was 0.80, the hand washing was 0.76 and theenvironment management was 0.76. There was positive correlation between the level of the awareness and the compliance on the nosocomial infection control. Conclusion: Therefore, it should be required that the development of the educational programs and the supportive policy of the hospital about infection control for the nurses.

Over the past 30 years, there has been an increase in the incidence of multifetal pregna-ncies, primarily because of the introduction of ovarian stimulants for ovulation induction and assisted reproductive technology ( ART ) in infertile patients. It is well established that multifetal pregnancies are associated with an increased frequency of the maternal complications and gre-ater perinatal morbidity and mortyality. The adverse outcome of multifetal pregnancies is dire-ctly proportional to the number of fetuses, primarily as an consequence of prterm delivery. Re-duction in the number of fetuses in multifetal pregnancies has been proposed as a way to impr-ove the perinatal outcome in this situation. Therefore, selective fetal reduction ( SFR ) is sugges-ted as a therapeutic option for continuation of pregnancy with fetuses mature enough to survi-ve. In this paper, we report our infertility clinic experiences with 6 patients who carried mult- ifetal pregnancies including 1 quintuplet, 1 quadruplet, and 4 triplets. from January, 1991 to May, 1996, transabdominal SFR was accomplished by fetal intrathoracic KCl injection at 9~10 weeks of gestation. After the prcedure, 4 patients remained as twin pregnancies, and 2 patients as single pregnancy. There have been 3 sets of twin deliveries and the 2 sets of single delivery. One case was aborted. Two patients were delivered after 37 weeks of gestation, 2 patients were at 35 weeks, and 1 patient at 24 weeks. All babies have been healthy after birth in patients after 35 weeks gestation. There was no fetal anomaly related to the procedure in the 6 cases. We concluded that transabdominal SFR is a rather safe and useful procedure that may improve the outcome of multifetal pregnancies.

PURPOSE: The purpose of this study was to investigate the actual condition of the disabled due to Occupational accidents based on the functional evaluation tool. METHOD: The data were collected from 2 Workers Accident Medical Corporation, 311 subjects between February and August, 2007. The tool comprised of six components including physical function, cognitive function, communication, emotional and disturbing behavior, nursing skills and rehabilitation needs. RESULTS: Among the disabled, the average point of physical function of 5 was found in 61.92% and to express and understand were evaluated as normal in 36.69% and 33.44%, respectively. Also, hearing and vision were evaluated as normal in 53.50% and 37.98%, respectively. 19.01% of the disabled had emotional problems and 13.78% had disturbing behavior. Most disabled were in need of nursing skills with 97.73% ROM and activities. The 78.18% and 76.90% of disabled were in need of rehabilitation because of right and left leg in full movement disorders, respectively. CONCLUSION: The evaluation score for the disabled caused by Occupational accidents was diverse showing 10 to 19 points and 140 to 150 points. The result means the care cost should be determined depending on the care needs of the disabled because there is such a diverse range of care needs for them.

PURPOSE: This study aims to develop a tool to predict occupational health patients' nursing needs or nursing time. METHOD: A tool was composed based on the materials and opinion of experts, and to verify the reliability and validity of the tool, nursing time of total 311 inpatients in 2 occupational health hospitals were surveyed. RESULTS: The developed tool was total 151 items and composed of physical function, cognitive function, communication, emotional and disturbance behavior, nursing skill, and rehabilitation need. The reliability of the tool was high, showing Cronbach's alpha coefficient of 0.95. But several items should be deleted for low corrected item-total correlation. According to the multiple regression analysis, physical function and rehabilitation need were shown to be the most powerful predictive variables for nursing time. CONCLUSION: The developed tool was appeared to have high reliability and validity. But further refinement of the tool is needed.

Isoliquiritigenin (ISL), a phenolic compound derived from licorice, exhibits various biological activities, including anti-inflammatory, anti-viral, anti-tumor, and antioxidant effects. However, the molecular mechanisms underlying its anti-cancer effects are not well understood in SK-MEL-28 melanoma cells. Melanoma, a highly aggressive and treatment-resistant cancer, remains a significant health challenge. This study investigates the anti-cancer effects of ISL, focusing on identifying reactive oxygen species (ROS)-mediated apoptosis mechanisms on SK-MEL-28 melanoma cells. Our results show that ISL treatment induces apoptosis in SK-MEL-28 cells, as evidenced by the cleavage of caspase-9, -7, -3, and PARP. ISL increased Bax expression, decreased Bcl-2 expression, and promoted cytochrome C release into the cytosol. ISL also reduced the expression of cell cycle markers, including cyclin D1, D3, and survivin. Notably, ISL treatment markedly increased intracellular ROS levels and pretreatment with N-acetyl cysteine, a ROS scavenger, abrogated the ISL-induced inhibition of the p38/mTOR/STAT3 pathway and prevented apoptosis.Moreover, ISL significantly diminished the constitutive phosphorylation of mTOR and STAT3 in SK-MEL-28 cells by blocking the phosphorylation of p38 MAPK, an upstream kinase of mTOR. Pharmacological inhibition of mTOR attenuated the STAT3 signaling, indicating that mTOR acts as an upstream kinase of STAT3 in these cells. Collectively, these findings demonstrate that ISL inhibits SK-MEL-28 cell growth by downregulating cell survival proteins and inducing apoptosis through ROS generation.

N-acetylcysteine (NAC) is widely recognized as the antidote of choice for acetaminophen overdose. Acetaminophen is a commonly used analgesic and antipyretic agent, and its use is one of the most common causes of poisoning worldwide. Acetaminophen toxicity may occur acutely when supratherapeutic amounts are ingested purposefully or unintentionally. Liver failure may occur in severe toxicity. However, if treated early, patients with acetaminophen poisoning generally recover uneventfully. Acetaminophen is metabolized to N-acetyl-p-benzoquinone imine (NAPQI), which is detoxified by conjugation with glutathione. In overdose, hepatic stores of glutathione are depleted and NAPQI binding to hepatocytes induces cell death and hepatic necrosis. NAC replenishes hepatic glutathione and may also act as a glutathione substitute, combining directly with the toxic metabolite. Intravenous NAC is indicated in patients who present with a history of acetaminophen overdose within the previous 8 to 10 hours, patients unable to tolerate oral NAC, and patients who present with evidence of fulminant hepatic failure. However, caution should be used in patients who have experienced previous hypersensitivity or anaphylactoid reactions to intravenous NAC, as well as in patients with asthma. The most common anaphylactoid reactions include rash, flushing, and bronchospasm. Adults should receive 150 mg/kg administered for 45 minutes, followed by 50 mg/kg administered for 4 hours, followed by 100 mg/kg administered for 16 hours. The total dose is 300 mg/kg delivered over 21 hours. Additionally, caution should always be used when intravenous NAC is prescribed and the amount of diluent is calculated. Monitoring of patients with a should include repeated neurologic and hemodynamic assessment.
