This study was done to compare the nutritional status of antioxidant vitamins between college women smokers and nonsmokers. Dietary intakes and serum levels of antioxidant vitamins were determined in 33 smokers and 42 nonsmokers residing in the Seoul area. Dietary intakes of vitamin A and C were determined by a quick and convenient dietary intake method. Serum vitamin C level was measured by 2,4-dinitrophenylhydrazine method and serum levels of vitamin A and E were measured by HPLC. The mean A intake of nonsmokers and smokers was 504.3 microgram R.E./day and 450. 4 microgram R.E./day and the mean vitamic C intake of nonsmokers and smokers was 51.6mg/day and 50.2mg/day, reapectively. There was no difference in the dietary intakes of antioxidant vitamins between smokers and nonsmokers. The serum vitamin A level, 0.71mg/1 in nonsmokers was not significantly different from that of 0.74mg/1 in smokers. However, the serum vitamin C level, 7.94mg/1 in smokers was 15% lower(p<0.05) than that of 9.30mg/1 in nonsmokers. The serum vitamin E level, 18.15mg/1 in smoders was also 34% lower(p<0.05) than that of 27.58mg/1 in nonsmokers. There was no significant correlation between dietary intakes and serum levels of vitamin A and C for both smokers and nonsmokers. These results suggest that cigarette smokers need more dietary intakes of vitamin C and E than do nonsmokers to reach the same serum level.

We have reported general principles of low vision aid prescription. But, we have not reported near vision aid prescription only. So, we analyse prescriptions of near low vision aid(diagnosis, type, magnification, etc) and present new near low vision aids that patients feels comfortable. We reviewed the clinical records of 100 patients who visited our low vision clinic more than twice and was prescribed near low vision aid for low vision. According to the data analysed, optic nerve atrophy was the most common etiology for low vision. Illuminated hand held magnifier(31.3%), telemicroscope with plus cap(27.7%), aspheric doublet sens(Clear Image II)(24.1%) were low vision aids most commonly used for near vision, but we knew new trend that newly prescribed aids(telemicroscope with plus cap, aspheric doublet lens) were prescribed more than illuminated hand held magnifier. After prescription of the low vision aid, visual acuity improved significantly (p<0.05). We examined contrast sensitivity test to measure the functional acuity and predict the visual prognosis after prescription of low visio aid.In addition,we studied the relationship between reading speed and the degree of contrast sensitivity and we knew that the relationship between degree of contrast sensitivity and reading speed was associated(p<0.05). Majority of patients(89%) were benefited from prescribed low vision aids.

In order to investigate the dietary intakes and physical characteristics in college women smokers, interviews using questionnaires were done on 33 smokers and 42 nonsmokers residing in seoul area. General living habits, dietary habits, food consumption frequency and nutrient intake by quick estimation were investigated through direct interviews with subjects. Subjects height, weight and blood pressure were measured, and body fat percentage were statistically analyzed using Bio-electrical Impedence Fatness Analyzer(GIF-891). All data were statistically analyzed by SAS PC package program ; percentage or mean and standard error were examined for each item, and the significant difference was evaluated by chi-square test or Student's t-test at alpha=0.05. In the analysis of taste and food preference, smokers consumed larger amount of alcohol and coffee than nonsmokers ; they also disliked sweet taste. The results of food consumption frequency data also showed that smokers consumed less fish, milk and fruits but consumed more instant foods than nonsmokers. As a result of anthropometric measurements, height, age, and body fat percentage showed no difference, but there was a significant difference in weight, BMI, systolic blood pressure, and diastolic blood pressure. Energy intake in nonsmokers was 1640 kcal/day(CHO : Pro : Fat=66.0 : 14.7 : 19.3), in smokers. Intakes of calcium, iron, vitamin C, vitamin A, vitamin B1, vitamin B2, and niacin in smokers were not significantly different from those of nonsmokers.

We conducted a retrospective study of 20 penetrating keratoplasty (19patients) for corneal opacity due to herpes simplex keratitis from January 1992 to February 1997 at National Medical Center. We exaniined f requeuey of graft rejection and recurrence of herpetic keratitis after penetrating keratoplasty. The patients were grouped into control & treatinent, group according to the use of antivirial drug after penetrating keratoplasty and we examined the difference in rate of recurrence between two groups. The follow-up period was from 8 months to 68 months, mean follow-up period being 29.6 months. Graft rejection was seen in 3 eyes out of 20 eyes (15.0%) and recurrence was developed 3 eyes out of 20 eyes (15.0%). Recurrent herpetic keratitis developed in 15.4%(2 of 13) of the eyes in control group and 14.3% (1 of 7) of the eyes in treatment group. There was no statistically significant difference in recurrence rate between two groups (p)0.05). Postoperative prophylactic antiviral treatment is not associated with decreased rate of herpes simplex keratitis recurrence.

The authors have evaluated the effect of topically applied 1% cyclosporine A for four weeks after limbal allograft transplantation for ocular surface stability in severely ocular surface damaged rabbits. A total eleven severely damaged rabbits were subdivided into three groups of four limbal autograft (AUTO), three limbal allograft (ALLO), four limbal allograft with topical application of 1% cyclosporine A five times daily for four weeks (ALLO-C). We examined ocular surface smoothness, clarity, corneal vascularization before surgery and three months after surgery, and classified three grade (success, partial success, failure) according to result. In AUTO, three eyes were success, one eye was failure. In ALLO, one eye showed inferior graft detachment and one eye was success, two eyes were failire. In ALLO-C, no graft detachment detected and one eye was success, two eyes were partial success, one eye was failure. We knew that. ALLO-C show more effective ocular surface stability than ALLO. These result suggest ALLO-C can be used as alternative treatment of AUTO in ocular surface reconstruction. But, rnore study for duration and concentration of cyclosporin A will be need.

PURPOSE: The purpose of this study was to identify the level of knowledge about dementia and to find the related factors in middle-aged adults. METHOD: The research design was a descriptive study by using a constructive self-report questionnaire with 34 items. Data were collected from 397 middle-aged adults using structured questionnaire. Data analysis was done by SPSS/WIN Programs using frequency, range from minimum to maximum, percentage, mean, SD, chi-square-test, t-test, ANOVA, and Duncan's Multiple Range test. RESULTS: The rate of correct answer of middle-aged adults was 68.7%, showing the mid-level of knowledge about dementia. There were significant differences according to age, education, marital status, job, income, information and information sources for dementia in middle-aged adults. CONCLUSION: These results indicate that Korean middle-aged adults need more education and counseling on dementia. Further studies are needed to overcome regionalism in sampling of this study and to develop standard measuring tools for the level of knowledge about dementia.

OBJECTIVE: To investigate the effect of steroid administration on the apoptosis and heat shock protein 70 (HSP70) expression after exercise in the animal model of Duchenne muscular dystrophy. METHOD: We measured Bcl-2, BAX and HSP70 expression by western blotting. 20 control and 20 mdx mice were divided into free-living (n=10) and exercise (n=10) groups. Free-living and exercise groups were further divided into steroid-treated and sham-treated groups to evaluate the effect of steroid administration. RESULTS: Apoptosis was most prominent in the sham-treated exercise group, while apoptosis was significantly reduced in the steroid-treated exercise group. HSP70 expression was maximized in sham-treated exercise group, whereas steroid administration inhibited HSP70 expression after exercise in muscular dystrophy animal model. Exercise loading was found to cause severe apoptosis but steroid administration alleviated apoptotic damage in mdx mice. CONCLUSION: HSP70 expression was suppressed in the steroid-treated exercise group, which suggests steroid might have major preventive effect in exercise-induced apoptosis of muscular dystrophy animal model.
