Pirpose: The aim of this study to analyze the association between history of diabetes mellitus (DM) with risk of prostate cancer (PCa) and cancer grade among men undergoing radical prostatectomy for PCa. Materials and Methods: 50 patients with DM and 50 patients without DM who undervent radical prostatectomy (RP) were included in the study. Age at biopsy, height, weight, digital rectal examination (DRE), pre-biopsy PSA levels, prostate volume, histopathologic diagnosis after surgery and gleason scores were collected data from all patients. Histologic material obtained at biopsy was given a Gleason score; tumours with a Gleason score ${\geq}7$ were considered high grade and <7 were considered low grade. Results: The mean age at the time of biopsy was 63.7 in patients with DM and 61.6 in patients without DM. Diabetic men had significantly lower PSA levels (p=0.01). Mean PSA level $7.04{\pm}2.85$ in patients with DM and $8.7{\pm}2.86$ in patients without DM, respectively. Also, diabetic men had higher RP tumor grade than men without DM (p=0.04). We found that HbA1c levels were higher in patients who have high grade prostate cancer (p<0.05). Conclusions: Diabetic men undergoing RP have lower PSA levels and have significantly higher grade PCa. We must be careful for screening PCa in patients with DM. Although the patients had lower PSA levels, they might have high grade disease.

Purpose: The purpose of this study was to identify predictors of depression and quality of life among older adults with osteoarthritis. The predictors included in the model were the client's characteristics(age, pain, disease duration, ADLs), personal resources(hardiness, self-care agency and family support), and depression. Method: 150 subjects who were older than 65 years and had diagnosis of osteoarthritis participated in the study. To answer the research questions, descriptive analysis, Pearson correlation, and hierarchical multiple regression were utilized using SPSS WIN program. Result: Older adults who were younger and had lower levels of pain and dependency on ADLs, and higher levels of self care agency and hardiness reported lower levels of depression($R^2=0.517$). Older adults who had lower levels of depression, pain, and dependency on ADLs, higher levels of family support and hardiness, and who are younger reported higher levels of quality of life($R^2=0.084$). Conclusion: Based on the findings of this study, development of nursing intervention program including pain reduction, enhancing ADL abilities and personal resources (hardiness, family support) can be suggested. Further study is needed to increase the ability of generalization of the study findings to the broader population.

This study was performed to investigate the effect of dietary $\beta$-carotene supplementation on lipid peroxide levels and antioxidant enzyme activities in alcoholic fatty liver rats. Forty five Sprague-Dawley male rats aging 8 weeks were used as experimental animals, which were divided into the control diet (CD) and the ethanol diet (ED) and the ethanol + $0.02\%$ $\beta$-carotene diet (EPD) groups and fed the experimental diet respectively for 5 weeks. After the feeding, rats were sacrificed to get blood and liver to analyze lipid and lipid peroxide levels and antioxidant enzyme activities. The mean body weight and food intake of the ethanol diet group was significantly lower than that of the control diet. The liver index (LI) of the ethanol diet group was significantly higher than those of the control diet and the $\beta$-carotene supplementation group. Serum levels of total lipid, triglyceride of the ethanol diet group were significantly higher than those of the control diet and the $\beta$-carotene supplementation group. Total cholesterol levels were not significantly different among all groups. HDL-cholesterol of the ethanol diet group was significantly lower than those of the control diet and the $\beta$-carotene supplementation group. Liver TBARS of the ethanol diet group was significantly higher than those of the control diet and the $\beta$-carotene supplementation group. Liver lipofuscin and conjugated diene levels were not significantly different among all groups. The superoxide dismutase activity of the ethanol diet group was significantly lower than those of the control diet and the $\beta$-carotene supplementation group. Catalase and glutathione peroxidase activities were not significantly different among all groups. Because v-carotene supplementation significantly decrease the serum total lipid, triglyceride, liver TBARS revels and increase the superoxide dismutase activity in alcoholic ratty liver rats, $\beta$-carotene supplementation seems to give beneficial effect for the alcoholics.

It is known that appropriate exercise changes body composition and improves coronary artery disease. This study was undertaken to evaluate the relationships between aerobic exercise, body composition, and the blood lipid levels in the middle-aged women(33 to 54 years old). The 57 subjects were divided into two groups based on their exercise: the aerobic exercise group(A group: 44) which performed at about $60\%$ of $VO_2max$ during over 6 months and the sedentary one(S group: 13). The percentages of body fat waist/hip ratio(WHR), body mass, and lean body mass of two groups were measured and compared in serum HDLC level and oxidized LDL level, the two most effective factors of coronary artery disease. The subjects in A group showed the lower percentages of body fat and WHR, when compared with the ones in S group. The body mass and lean body mass of A group subjects were higher than those of S group subjects. The serum HDL-C level$(58.6\pm12.7mg/mL)$ was significantly higher for A than S group subjects.(p<0.05) The sem ox-LDL level $(6.64\pm4.11Eu/mL)$ for A group subjects was lower than S group ones. The fat mass showed significantly positive correlations with atherogenic index(AI)(r=0.301, p<0.05), and with blood glucose levels(r=0.334, p<0.05). Also the WHR whowed significantly positive correlations with LDL-C levels(r=0.277, p<0.05), and with AI(r=0.466, p<0.01). In summary, the subjects in A group have the lower percentages of body fat and WHR, when compared with the ones in S group. Also, A group subject showed a tendency that exercise enhances serum HDL-C levels and decreases oxidized LDL levels. And aerobic exercise showed positive results which change body composition and improve blood lipid levels. There were significantly positive correlations among the percentages of body fat At and blood glucose level. These results suggest that moderately intensive exercise is a significant factor in reducing coronary artery disease.

This study was designed to determine whether acute fructose or sucrose administration at different levels (0.05 g/kg, 0.1 g/kg or 0.4 g/kg body weight) might affect oral glucose tolerance test (OGTT) in normal and type 2 diabetic rats. In OGTT, there were no significant differences in glucose responses between acute fructose- and sucrose-administered groups. However, in normal rats, the AUCs of the blood glucose response for the fructose-administered groups tended to be lower than those of the control and sucrose-administered groups. The AUCs of the lower levels fructose- or sucrose-administered groups tended to be smaller than those of higher levels fructose- or sucrose-administered groups. In type 2 diabetic rats, only the AUC of the lowest level of fructose-administered (0.05 g/kg body weight) group was slightly smaller than that of the control group. The AUCs of fructose-administered groups tended to be smaller than those of the sucrose-administered groups, and the AUCs of lower levels fructose-administered groups tended to be smaller than those fed higher levels of fructose. We concluded from this experiment that fructose has tendency to be more effective in blood glucose regulation than sucrose, and moreover, that smaller amount of fructose is preferred to larger amount. Specifically, our experiments indicated that the fructose level of 0.05 g/kg body weight as dietary supplement was the most effective amount for blood glucose regulation from the pool of 0.05 g/kg, 0.1 g/kg and 0.4 g/kg body weights. Therefore, our results suggest the use of fructose as the substitute sweetener for sucrose, which may be beneficial for blood glucose regulation.

Objective: This study aimed to examine the effects of adult children's marriage-delay on their parents' mental health. Furthermore, this study investigated how the influence of adult children's marriage-delay on parents' mental health could vary depending on the coresidence and employment status of the marriage-delayed adult children. Method: Two waves of Korean Longitudinal Study of Ageing (KLoSA) were used for the analyses. Multiple regression models were conducted with 2,938 Korean parents who had at least one child, regardless of gender (aged 33~44). Results: First, adult children's marriage-delay was related to lower levels of parents' life satisfaction. Second, the levels of parents' life satisfaction were low regardless of residing with their marriage-delayed adult children, and the parents who were not living with their marriage-delayed adult children showed lower levels of life satisfaction than parents living with marriage-delayed adult children. Third, only the parents with unemployed marriage-delayed adult children showed significantly higher levels of depression. However, the levels of parents' life satisfaction were low regardless of the employment of marriage-delayed adult children, and the parents of unemployed marriage-delayed adult children showed lower levels of life satisfaction than the parents of employed marriage-delayed adult children. Conclusions: It is necessary to consider the effects of marriage, employment and coresidence of adult children on their parents in order to enhance the mental health of the parents. Also, the effects of marriage-delay on intimate relationships, such as family dynamics, need to be explored more in further research.

This study was conducted to investigate the effects of dandelion (Teraxacum platycarpum) extracts obtained by only water and with ultrasonification on antioxidative system and lipid metabolism in high cholesterol-fed rats. Five groups of rats were given high cholesterol diets for 8 weeks. The control group received without dandelion extracts and the other four groups received with one of dandelion extracts for 4 weeks respectively ; TP-N-1(100 mg/kg/day of Teraxacum platycarpum water extract), TP-N-2(200 mg/kg/day of Teraxacum platycarpum water extract), TP-S-1(100 mg/kg/day of Teraxacum platycarpum water-ultrasonification extract), TP-S-2(200 mg/kg/day of Teraxacum platycarpum water-ultrasonification extract). The results are summarized as follows; The hepatic and plasma TBARS levels significantly decreased in the dandelion extracts groups compared to those of no treatment group. Especially the group TP-N-2 was comparatively best among those. TP-N-2 groups had significantly higher levels of glutathione peroxidase (GSH-Px) and catalase activities. There was no significant difference between dandelion extracts groups and no treatment group in SOD levels. In plasma triglyceride level, plasma FFA level, TP-S-2 group had significantly lower levels than that of the other groups. In plasma glucose levels, dandelion extracts group were similar to those of normal rats. Plasma total cholesterol levels significantly decreased in the TP-S-2 group compared to those of the other groups. HDL levels were also significantly higher than those of the other groups. Compared with those of no treatment group, dandelion extract groups had significantly higher levels of LDL. In liver total cholesterol level, TP-S-2 groups had significantly lower levels than that of the other groups. Compared with those of no treatment group, dandelion extracts groups had significantly lower levels of liver triglyceride, but especially the TP-S-2 group showed comparatively the best significant effect among those. TBARS, triglyceride, LDL, FFA levels significantly decreased in TP-S-2 groups compared to the other four groups. HDL levels was also significantly higher than the other four groups. According to the above result, it could be suggested that ultrasonic extraction have the upper hand in lipid metabolism and water extraction have the advantage of antioxidative system.

Purpose: In addition to regulating calcium and phosphorus homeostasis and bone metabolism, vitamin D is known as an immune modulator. Recently, there has been increased worldwide interest in the association between low levels of vitamin D and allergic diseases. The purpose of this study was to assess the relationship between serum vitamin D levels and allergic/vasomotor rhinitis (AR/VR) in children. Methods: This study included 164 patients. The sample included 59 patients with AR, 42 patients with VR, and 63 controls. Their ages ranged from 0 to 16 years. We examined the levels of 25-hydroxyvitamin D, Immunoglobulin E, specific IgE, and eosinophil cationic protein; peripheral blood eosinophil count; and the results of a skin prick test. Results: Serum 25-hydroxyvitamin D levels were $19.0{\pm}8.5ng/mL$ in the AR group, $25.5{\pm}10.9ng/mL$ in the VR group, and $26.9{\pm}10.7ng/mL$ in the control group. After adjustment for body mass index and season at the time of blood sampling, vitamin D levels in the AR group were lower than those of the VR group (P=0.003) and control group (P<0.001). Vitamin D levels were inversely correlated with Immunoglobulin E levels (r=-0.317, P<0.001). AR patients with food allergy or atopic dermatitis did not have lower levels of 25-hydroxyvitamin D than AR patients without these diseases. Conclusion: This study demonstrates a possible relationship between vitamin D levels and allergic rhinitis in Korean children.

The purpose of this study was to investigate daily nutrient intakes, serum minerals and lipids in university students majoring in physical education. Anthropometric measurement, dietary survey, and blood analysis were conducted and compared between physical education major (PM) and other major (OM) students. Average age was 21.3 years for PM students and 20.8 years for OM students. Body weight and BMI of PM students were significantly higher than those of OM students (p<0.05). Systolic blood pressure of PM students was significantly lower than that of OM students (p<0.05). Daily energy intake was 2,047.4 kcal for PM students and 2,393.9 kcal for OM students, indicating a significant difference. Carbohydrate and vitamin B1 intakes of PM students were significantly lower than those of OM students. Serum calcium was significantly higher in PM students while serum phosphorus and magnesium levels were higher in OM students. Serum total cholesterol and LDL-cholesterol were significantly lower in PM students while HDL-cholesterol was lower in OM students. In conclusion, university students who major in physical education showed higher serum calcium, lower serum phosphorus and magnesium, and lower systolic blood pressure and serum cholesterol levels than other major students. These results show that physical activity as a major course of study is associated with decreased blood pressure and blood lipids as well as altered serum mineral levels.

The purpose of this study was to investigate the potential hypolipidemic effect of adlay extract in streptozotocin-induced diabetic rats. Fifty six rats were fed either a control diet or adlay extract diets of : Methanol 1%(Ml%) ; Methanol 2%(M2%) ; Methanol 4%(M4%) ; Chloroform-Methanol 1%(CMl%) ; Chloroform-Methanol 2%(CM2%) ; Chloroform-Methanol 4%(CM4%) for 3 weeks. The amount of extracts added was 1%, 2% or 4% by diet weight respectively. The levels of glucose, total cholesterol(TC), high-density-lipoprotein cholesterol (HDL-C), free-fatty acid(FFA) and triglyceride(TG) in plasma, liver and skeletal muscle were compared. Among diabetic rats, there were no significant differences in the plasma level of glucose and TC regardless of a different extraction procedure or different amount of extracts added. While the plasma 7G level tended to increase with times passed in diabetic control group, was not increased with times passed in CM groups and was significantly lower in CM groups at 3rd week. Compared to the diabetic control group, the levels of FFA tended to be lower in all M groups and were not different in all CM groups. The levels of HDL-cholesterol were not different in all M groups and were significantly lower in all CM groups than diabetic control group. Compared to diabetic control group, liver triglyceride level was lower in M4% group and no significant difference was seen in Ml%, M2% and all CM groups. Muscle triglyceride level tended to be lower in Ml%, M2% and CM2% group and significantly was lower in M4% and CM4% group. Thus, it can be suggested that a CM extract of adllay could have a potential hypotriglyceridemic effect on diabetic subjects. (Korean J Nutrition 31(5) : 921∼926, 1998)
