  • In this study, in order to confirm the ameliorative effects of onion (Allium cepa L.) flesh and peel on amyloidbeta (Aβ)-induced cognitive dysfunction, we evaluated their in vitro neuroprotection and in vivo cognitive functions. As the result of in vitro neuroprotection, the protective effect of the ethyl acetate fraction of onion flesh (EOF) on Aβ-induced cytotoxicity was similar to that of the ethyl acetate fraction of onion peel (EOP). In the behavioral tests, the EOF and EOP effectively improved the Aβ-induced learning and memory impairments. For this reason, it could be concluded that the EOF and EOP improved the antioxidant activities (superoxide dismutase, oxidized glutathione/total glutathione, and malondialdehyde) in brain tissue. In addition, the EOF and EOP effectively activated mitochondrial functions by protecting the mitochondrial membrane potential, ATP, mitochondria-mediated protein (BAX and cytochrome c), and caspase 3/7 activities. The EOF and EOP also improved the cholinergic system (acetylcholinesterase and acetylcholine). Therefore, we suggest that onion could be used for management of Aβ-induced cognitive dysfunction.

  • The Opuntia extract has been traditionally used to treat diabetes, inflammation, and rheumatoid arthritis in oriental medicine. The purpose of this study is to investigate characteristics of biological activity between Opuntia humifusa and Opuntia ficus-indica which is cultivating in korea using cell-free system or cell-based assay. O. humifusa extract effectively inhibited ${\alpha}$-glucosidase activity or improved the immune function, and its biological activity was more effective than O. ficus-indica extract. The scavenging activity of DPPH radical and the inhibitory effect of tyrosinase similarly showed by O. humifusa and O. ficus-indica extract, however neuroprotective effect only showed a tendency to increase compared with control in PC12 cells. Therefore the results suggest that O. humifusa can be a useful agent for treatment of diabetes and immunodeficiency.

  • Purpose; The purpose of this study was to develop an instrument to measure sexual satisfaction in Korean adults. Method: Development of items for the instrument was done by a collecting, reorganizing, reducing and selecting process based on the literature. A total of 19 items were selected in this process. For evaluation of the appropriateness of the 19 items, questionnaires were given to an expert group consisting of 18 professionals (7 men and 11 women). Eighteen items having a response of 70% in 'very good' item or 'good' item were included as items for the instrument. With these 18 items, a 5 point Likert scale was developed, and reliability and validity tests of the scale were done. The subjects for the test were 1,127 Korean adults living in 11 areas in Korea, Data were collected from Dec. 1, 2000 to Feb. 28, 2001 and analyzed with SPSS/PC+ 10.0 program. Item analysis and factor analysis were used to assess the reliability and validity of the scale. Chronbach alpha and corrected item-total correlation were obtained to verify internal consistency, and principal component analysis with the varimax rotation was used to identify structure validity of the developed tool. Result: Reliability of the scale was .9503 and corrected item-total correlations of the items were distributed from .5208 to 7899. As a result of the factor analysis, the items were categorized into three factors. The cumulative variance of the three factors was 67.1%, and all of the variances of the factors were above 5%. Because factor 1 (8 items) indicated a special feeling of psychological satisfaction with sexual activity, it was named 'psychological factor'. Factor 2 (8 items) indicated a feeling of satisfaction in the interaction with sexual partner through communication and variation, therefore it was named 'interactional factor'. Factor 3 (2 items) was about the frequency and duration of sexual intercourse and indicated physical dimensions of satisfaction, so it was named 'physical factor'. The average score for sexual satisfaction of the 1,127 subjects was 65.32 (${\pm}12.71$), and histogram of the score showed a normal distribution with skewness - .425. Conclusion: Finally, a Korean Sexual Satisfaction Scale(KSSS) was accepted as a 5 point Likert scale with 18 items after the statistical test for reliability and validity. In conclusion, KSSS is a useful instrument which is valid and reliable can be used to understand the sexuality of Korean adults.

The Internet standard VR format. VRML(Virtual Reality Modeling Language) is used to represent the 3I) medical image data. The 3D images are reconstructed from medical image data which are enerated by medical imaging systems such ans CT(Computerized Tomography). MRI(Magnetic Resonance Imaging). PET(Positron Emission Tomograph), SPECT(Single Photon Emission Compated Tomography). We implemented the medical image information system shich rses a surface-based rendering method for the econstruction of 3D images from 2D medical image data. In order to reduce the size of image files to be transfered via the Internet. The system can reduce more than 50% for the triangles which represent the surfaces of the generated 3D medical images. When we compress the 3D image file, the size of the file can be redued more than 80%. The users can promptly retrieve 3D medical image data through the Internet and view the 3D medical images without a graphical acceleration card, because the images are represented in VRML. The image data are generated by various types of medical imaging systems such as CT, MRI, PET, and SPECT. Our system can display those different types of medical images in the 2D and the 3D formats. The patient information and the diagnostic information are also provided by the system. The system can be used to implement the "Tele medicaine" systems.

  • The purpose of this study was to find out women's need and level of knowledge about episiotomy, pain and discomfort related to episiotomy on a cross-sectional survey design. The subjects were 102 postpartal women agreed on oral consent. 34 postpartal women admitted at obstetric ward of H university hospital, 34 postpartal women admitted at 2 Sanhujoriwons, and 34 women within one year afterbirth. They were selected in Seoul, Korea. Data were collected from July, 1 to September 30, 2000, by a structured questionnaire. The instrument used for this study was a questionaire consisted of 5 items of general characteristics, 12 items of obstetric characteristics, 10 items of level of knowledge (Chronbach $\alpha$ .8176), 8 items of need of education(Chronbach $\alpha$ .8836), 3 items of pain (Chronbach $\alpha$ .9252), and 3 items of discomfort (Chronbach $\alpha$ .8092). The data were analyzed by the SPSS/PC+ program using t-test, ANOVA and Scheffe test as a post hoc and Pearson Correlation Coefficient. The results of the study were as follows; 1. 63.2% of respondents had right answer on 6-8 items among 10 items. Only 4.4% of women got right answer on 10 items all. 2. The need of education was high(4.45%) on all items and the range of score was $4.25{\sim}4.64$. 3. The strength of pain was the highest within one week afterbirth(5.93/10) and became lower in 8-14 days afterbirth(2.55). And after 15days of postpartum, the pain level became to the lowest level(1.08). However, pain was delayed until more than one month afterbirth. 4. The level of discomfort was the highest one week afterbirth(6.88/10) and became lower in 8-14 days afterbirth(4.20). And after 15days of postpartum, the discomfort level became to the lowest level(2.47). Universally, the degree of discomfort was higher than pain. 5. There was a strong positive correlation between discomforts and pain ($r=.752^{**}$) and weak positive correlation between discomforts and the level of educational need($r=.308^*$). In conclusion, women have a right to choose whether she will have episiotomy or not according to her decision making based on the comprehensive knowledge of episiotomy before they get episiotomy with consent process and explanation in detail. Women health care providers like nurses have a responsibility to do conscious raising and empowerment for women so that they could lead themselves to choose given medical treatments for women's health and wellbeing and the quality of life in her life cycle.
