Treatment of oral cancers with chemotherapeutic agents are evaluated as an effective method for remission to reduce cancer proliferation nowadays. But, minimization of side-effects such as bone marrow suppression, gastrointestinal toxicity and renal damage is another problem to be solved. Thus, a possible approach to develop a clinically applicable chemotherapeutic agents is to screen anticancer activity among traditional medicinal plants which have been used for thousands of years with very low side-effects in orient. In this study we focused on anti-oral cancer activities of momordin, which was medicinal plant extracts that was revealed anticancer activities, on KB cell(oral cancer cell). The results were as follow : 1. Momordin showed the excellent anti-oral cancer activity against KB cells. Obtained IC50 value of Momordin was 10.4 microgram/ml. 2. When KB cells were treated with Momordin, dose and time dependent DNA fragmentation of KB cells were observed. DNA fragmentation was initiated on three days at the concentration of 20 microgram/ml Momordin. 3. Flow cytometry showed dose-dependent apoptotic cell increase of KB cells on Momordin. 18.55% apoptotic cell were observed up to 72 hours at the concentration of 20 microgram/ml of Momordin 4. Momordin induced nonspecific apoptosis without specific cell cycle arrest. 5. Through MTT assay, DNA fragmentation assay and flow cytometric analysis. anticancer effect of Momordin against KB cell was induce of apoptotic cell death.

Corneal endothelial damages following Nd: YAG laser application were evaluated rabbits. The first group underwent anterior capsulotomy, while the second group received laser applications at the corneal center and anterior capsule. The rabbits were evaluated with the intraocular pressure, the corneal endothelial cell number, the thickness of the corneal center, and the morphologic change of the cornea, before laser application and at postaplication 1 day, 7 day, and 14 day. But the endothelium was damaged when laser shots were applied at the cornea center and anterior caps ulotomy. In ophthalmologic procedure with Q-switched Nd:YAG laser, the minimal effective poser should be selected, the laser beam should be applicated on extremely fine focus and contact lens should be used to minimize the corneal endothelial injury.

PURPOSE: This study was conducted to identify job experiences of male hospital nurses. METHODS: Data were collected from 20 male nurses working at general hospitals, through semi-structured in-depth interviews. The interviews were recorded and subsequently transcribed verbatim. Using content analysis, data were coded and categorized. RESULTS: The analyzed domains were motivations for choosing nursing, occupational experiences (3 subdomains), and attitudes toward the future. A total of 85 significant statements were selected from the data and classified into 32 categories. The nurses' motivations for choosing nursing were advantages of employment, their aptitude, scarcity value of men, professionalism and job security, good promotion, stable income, and family influence. In occupational experiences, they were assigned to special fields and dissatisfied with vertical relationship, promotion system, their salary, and gaps in military service time; they had difficulties in adapting to female-dominated groups and encountered gender role stereotype and preconception; they were satisfied with their distinguished performance, but had damaged self-esteem, and were stressed and disappointed in their work. In their attitudes toward the future, they considered their career changes, but tried to make professional and personal advancement. CONCLUSION: These findings have implications for recruiting and retaining male nurses in clinical settings.

PURPOSE: To determine the type and degree of effect that a hot footbath has on sleep quality and fatigue level in older Korean adults. METHODS: A non-equivalent control group quasi-experimental design was used. Fifty participants from a long-term care facility in Kwangju, South Korea, were randomly selected and assigned to two groups: experimental group (27 participants) and control group (23 participants). The participants in the experimental group received hot footbaths in a temperature-controlled water tub of 42degrees C. They soaked their feet up to 20cm above the ankles for 30 minutes before going to bed for 3 nights. Actigraphy was used to measure their sleep patterns. The data were analyzed using the SAS program. RESULTS: After the intervention, the total sleep satisfaction rate of the participants increased, while sleep latency and fatigue decreased significantly in the experimental group compared to the control group. CONCLUSION: The study results suggest that hot footbaths are beneficial for older Korean adults in enhancing sleep quality as well as reducing fatigue. Therefore, hot footbaths are recommended as a nursing intervention to improve sleep quality and to reduce fatigue in older Korean adults.
