PURPOSE: There have been global initiatives and efforts over the last decade to manage patient safety. Thus aims of this study were to examine university hospital nurses' perceptions of patient safety culture and levels of safety control, and to identify factors that affect patient safety management activities. METHODS: Participants were 222 nurses who had worked as nurses for more than one year and who conducted patient safety management activities at a university hospital. Data were collected using structured questionnaires and were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson correlation coefficient, and multiple regression analysis with SPSS/WIN 20.0 computer program. RESULTS: General factors which positively impacted nurses' patient safety management were total length of work in nursing, total length of work in present hospital, and experience of a patient safety accident along with safety factors of perception of communication about accident related events and frequency of reporting accident events. These variables explained 45% of the variance in patient safety management activities. CONCLUSION: The findings from this study suggest solutions to promote patient safety management activities in hospitals and provide basic background for nursing education intervention strategies to promote safety control and patient safety management activities intended for nurses.

With the aim of establishing bio-indices for the development of multistep hepatotumorigenesis, rats were fed water containing 0.01% diethylnitrosamine (DEN) ad libitum for 13 weeks. This treatment with DEN only made it possible to induce hepatic tumors in 100%. After the DEN administration, several clinical symptoms were observed including minor behavioral changes, brittleness of hair and a decrease in water and food intake. The concentration of total serum protein and albumin in all treated groups was significantly lower than in non-treated controls (p<0.05). Increase of specific enzyme (AST, ALT and GGT) activity (p<0.05), variable tumor size and hepatomegaly of the liver was observed in all rats treated with DEN for 10 weeks. Both hepatocellular carcinoma and cholangiocarcinoma were found in the same livers at the same time, and were prominently developed after 12 weeks. In case of carcinoma, some of the livers showed more or less advanced states over the 12-15 weeks period. In the present study, hepatocellular carcinoma was developed by treating DEN in only the drinking water, without any other carcinogens or without partial hepatectomy. These results indicate that DEN is a new carcinogen that acts directly on it the liver, moreover, it might be very useful for investigating hepatotumorigenesis.

Vanadate is a trace element in animal tissues and has been known to inhibit NA(+)-K(+) ATPase in various tissues including skeletal and cardiac muscles and smooth muscles. Vanadate shows contractile actions on various types of smooth muscles. Prolonged dietary administration of vanadate has been shown to cause arterial hypertension, increased peripheral resistance, and a marked reduction of coronary, visceral and renal blood flow.In isolated vascular smooth muscle of aorta, application of vanadate caused contraction. These studies have been conducted the preparation of vascular smooth muscles from which endothelial cell were removed. It has been reported that endothelial cell releases relaxing factor(s) (endothelium-derived relaxing factor, EDRF) in response to acetylcholine and a number of other stimuli and also produces vasoconstrictor substances (endothelium-derived contracting factor, EDCF). The aim of this present experiment is to elucidate whether vascular response of isolated rabbit aorta induced by vanadate are endothelium dependent or not. The result obtained were summarized as follows ; 1) When endothelium was intact, vanadate induced vascular relaxation of aorta precontracted with norepinephrine. But K+ induced contraction was augmented by vanadate in the aorta with or without endothelium. Whereas relaxation produced by vanadate precontracted with angiotensin II was endothelium-independent. 2) Hemoglobin, methylene blue, hydroquinone, and verapamil inhibited vanadate-induced vascular relaxation. But indomethacin and quinacrine had no effect on vanadate induced vascular relaxation. From the above results, it is speculated the vanadate act on endothelium, modifies the synthesis or release of endothelium-dependent relaxing factor and thus changes the contractile responses to norepinephrine in rabbit aorta.

Hyperventilation is a common form of anesthetic management in neurosurgical patients with increased intracranial pressure. Acute hypocapnia through hyperventilation causes an increase in cerebrovascular resistance which decreases the cerebral blood flow within one minute. When the hyperventilation is sustained, the cerebral blood flow gradually rises toward normal. We performed this study for evaluation of the changes of acid-base balance in cerebrospinal fluid (CSF) according to duration of acute hyperventilation. We have studied 12 patients for elective surgery for cerebral aneurysm with a relatively clear mental state. The patients underwent induction of anesthesia with thiopental, fentanyl and vecuronium. After intubation, their ventilation was controlled and maintained at a PaCO2 of about 30 mmHg. Samples in arterial and lumbar CSF were obtained at hourly intervals for 6 hours after the onset of hyperventilation. The results were as follows: 1) The PaCO2 was low 30s mmHg and all arterial blood values were not changed throughout the period of observation. 2) The values of CSF were changed; the pH of CSF was increased for 3 hours and then gradually decreased after 4 hours, carbon dioxide tension was a steady state after an initial fall for 2 hours, HCO3-, was decreased from 2 hours and more significantly decreased after 5 hours, and the base excess was more significantly negative after 5 hours of hyperventilation. From the above data, we conclude that prolonged hyperventilation produces first a rise in CSF pH by decreased CSF PCO2 and then gradually a fall in CSF pH by decreasing CSF HCO3-, concentration, and measurable compensated acidosis in CSF was initiated within 5 hours after onset of hyperventilation.

PURPOSE: This study was done to examine the effects of oral care with essential oil in improving the oral health status of hospice patients with terminal cancer. METHODS: The participants were 43 patients with terminal cancer admitted to K hospital in G city, Korea. Twenty-two patients were assigned to the experimental group and 21 to the control group. Participants in the experimental group received special mouth care with essential oil (application of essential oil mixture consisting of geranium, lavender, tea tree, and peppermint). The control group received special mouth care with 0.9% saline. The special mouth care was performed twice daily for one week in both groups. The scores for subjective oral comfortness, objective oral state, and numbers of colonizing Candida albicans were measured before and after the treatment. RESULTS: The score for subjective oral comfortness and objective oral state were significantly higher in the experimental group compared to the control group. The numbers of colonizing Candida albicans significantly decreased in the experimental group compared to the control group. CONCLUSION: Oral care with essential oil could be an effective oral health nursing intervention for hospice patients with terminal cancer.
