This study was performed to investigate the effects of food habits and life style on the skin health of young Korean females in their late teens and twenties. The study focused on facial skin and used a self-administered questionnaire survey, an examination of skin type, and pH tests. More than half of the females had combination skin type or pH level higher than 5.8 which is regarded as normal. The variables that turned out to significantly (p<0.05) effect their facial skin types were body mass index (BMI), the type of residence, the amount of water intake, whether or not they intake drinks, the frequency and amount of alcohol drinking, favorite foods as side dishes at meals, intake frequency of fruit, the dairy, seaweed, and fast food, the frequency of washing their faces per day, the method of how they used water during face washing, whether or not they had professional skin care, and whether or not they wore color make up. The variables of the females' age, BMI, the amount of alcohol drinking, the frequency and duration of exercise, the controlling methods of stress, their favorite foods as side dishes at meals, and the intake frequency of soy products or animal foods significantly affected their facial pH levels (p<0.05). The results of this study indicate that some food habits and life styles are significantly related with facial skin health. More importantly BMI and favorite foods as side dishes during daily food intake could have remarkable effects on facial skin health.

To assess the dietary therapy compliance of non-insulin-dependent diabetes mellitus (NIDDM) patients living in Daegu, we evaluated diet adequacy levels by index of nutritional quality (INQ), nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and dietary variety score (DVS) with food exchange system and Korean recommended dietary allowances (KRDA). One day dietary intake was measured by 24 hour recall method for 229 subjects over 20 years of age. Average daily energy intake was 1444 kcal. The relative ratio of carbohydrate, protein and fat in terms of energy intake was 69.4：14.5：16.0. The nutrient adequacy ratio (NAR) for Vitamin A, B$_2$, calcium were lower than 0.5 and MAR was 0.65. It appeared that the consumption of each food group as compared to prescribed food exchange unit was insufficient, in the order of dairy group (10.2 $\pm$ 25.2%), fruits group (58.2 $\pm$ 71.2%) and oils & fats group (42.9 $\pm$ 42.0%). The dietary variety score (DVS) was evaluated as an useful tool for diabetes' meal management when we accept minimum intake as 0.3 of food exchange unit. We found significant correlation between food groups and anthropometric indices: cereals group and % total body fat (r = 0.251, p < 0.01), meat group and waist circumference (r = 0.241, p < 0.01), vegetables group and WHR(r = 0.139, p < 0.05), and oils poop and WHR(r = 0.165, p < 0.05). from these results, we concluded that overall status of dietary intake of NIDDM patients in Daegu area was insufficient not only in quality but also in quantity. It is suggested that nutrition education for NIDDM patients should stress on balanced food consumption to meet proscribed amount by six food group to improve the inadequacy of dietary status.

The purpose of this study was to investigate the effects of green tea catechin o n free radical generation system and peroxidative damage in the liver of streptozotocin(STZ)-induced diabetic rats. Spragu-Dawley male rats weighing 150$\pm$10gm were randomly assigned to one normal and three STZ-induced diabetic groups; diabetic groups were classified to catechin free diet(DM-oC group), 0.5% catechin diet(DM-0.5C group) and 1% catechin diet(DM-1C group) according to the levels of dietary catechin supplementation. Diabetes was experimentally induced by intravenous injection of 55mg/kg of body wt of STZ in citrate buffer(pH 4.3) after feeding of three experimental diet for 4 weeks. Animals were sacrificed at the 6th day of diabetic states. Activities of serum glutamic oxaloacetic transaminase(GPT) in DM-oC groups were higher than those of the normal group, and those in catechin supplementation group were similar to those of the normal group. Liver lipid peroxide values increased by 153%, 49%, and 27% in Dm-oC, DM-0.5C and DM-0C and Dm-1C but was not significantly different in catechin supplementation groups compared with the normal group, and liver cytochrome $P_{450}$ contents was similar to result of XOD activity. In electron microscopic examination of liver, lysosome was relatively scattered in Dm-oC and Dm-0.5C group and preserved normal shapes in DM-1C group. The present results indicate that STZ-induced diabetic rats are more sensitive to oxidative stress, leading to the acceleration of lipid peroxidation process, but this was reduced by anti-oxidative effect of high level of dietary catechin. It is concluded that dietary catechin serves as powerful antioxidant against lipid peroxidation in diabetic rats.

This experiment was performed to examine the influences of high ambient temperature on milk production, nutrient digestibility, energy and protein sufficiency ratio, and plasma metabolites concentration in lactating cows. In a $2{\times}2$ crossover design, four multiparous lactating Holstein cows were maintained in a chamber under treatment of constant moderate ($18^{\circ}C$) ambient temperature (MT) or high ($28^{\circ}C$) ambient temperatures (HT). The DMI and milk protein yield were significantly lower in HT (p<0.05). The milk yield, milk lactose yield, and milk SNF yield tended to be lower in HT (p<0.10). No statistical differences for 4% fat-corrected milk and milk fat yield were observed. Rectal temperatures were significantly higher in HT than MT (p<0.05). The apparent DM, OM, ether extract, CF, and ash digestibility did not differ between treatments. On the other hand, the apparent CP digestibility was increased significantly (p<0.05) and nitrogen free extract tended to increase (p<0.10) in HT. The sufficiency ratio of ME and DCP intake for each requirement tended to be lower in HT than in MT (p<0.10). Concentrations of total protein (TP), albumin, and urea nitrogen in plasma did not differ between treatments. Plasma 3-methylhistidine (3MH) concentration as a marker of myofibrillar protein degradation tended to be higher in HT (p<0.15). In conclusion, high ambient temperature was associated with a lower energy and protein sufficiency ratio, and decreased milk protein production, even though the body protein mobilization tended to be higher.

Objectives : We observed the possibilities that blue honeysuckle has favorable analgesic or refinement effects on the Primary dysmenorrhea (PD) in rats. Methods : Estradiol benzoate and oxytocin were used to induce the PD rat model. And Blue honeysuckle concentration lyophilized powders (BH) 500, 250 and 125 mg/kg and 500 mg/kg of Lonicerae Flos aqueous extract lyophilized powders (LF) were orally administered, once a day for 10 days at 30 min after each estradiol benzoate treatment. Then the changes on the body weights and gains during experimental periods, abdominal writhing response for analgesic activities, uterine weights, uterus lipid peroxidation, antioxidant defense system - glutathione contents, superoxide dismutase and catalase activities, NF-κB and COX-2 mRNA expressions were monitored with uterus histopathology including immunohistochemistry for tumor necrosis factor (TNF)-α and inducible nitric oxide synthase (iNOS).. Results : Inflammatory and oxidative stress mediated PD signs were favorably and dose-dependently inhibited by 10 days continuous oral administration of three different dosages of BH - 500, 250 and 125 mg/kg as comparable to those of indomethacin(IND) 5 mg/kg treated rats in BH 500 mg/kg administered PD rats, and similar to those of LF 500 mg/kg in BH 125 mg/kg, at least in a condition of the present PD rat model. Conclusions : The results suggest that BH has favorable analgesic and refinement activities on the estradiol benzoate and oxytocin treatment-induced PD signs through anti-inflammatory and antioxidative potentials.

Objectives : In this paper, lung atrophy syndrome[肺痿] in 『Huangdineijin(黃帝內經)』 and 『Jinguiyaolue(金匱要略)』 were compared, followed by examining its relation with upper wasting thirst[上消]. Also, ways in which psychological factors that contribute to lung atrophy syndrome could cause upper wasting thirst were studied. Methods : Verses from 『金匱要略·肺痿肺癰咳嗽上氣病脈證治』 and 『素問·痿論』 were analyzed based on various annotators's opinions to determine the cause and mechanism of lung atrophy syndrome and its relationship with upper wasting thirst. Results : In 『Jinguiyaolue(金匱要略)』, lung atrophy syndrome is described as the heat of the upper body entering the lungs to dry it out. The description in 『Suwen(素問)』 differs in that it accompanies atrophy symptoms, but the mechanism is the same. Lung atrophy syndrome in 『Jinguiyaolue』 could come from wasting thirst, while wasting thirst can be accompanied in deficiency caused by chronic lung atrophy syndrome. Heat in the lungs is caused by psychological factors where the person has lost its subject of possession or was unable to attain what was desired. When expanded to include heart atrophy syndrome[心痿] and lung atrophy syndrome[肝痿], the reason for upper wasting thirst could include immense sadness or excessive indulgence in pleasure due to unmet desires. Conclusions : Although diabetes and wasting thirst are not identical, application of wasting thirst pattern differentiation to diabetes treatment and management could lead to tailored treatment of each patient. Moreover, the five zhang pattern differentiation from the 『Suwen(素問)』 could increase treatment efficacy when applied to conditions caused by stress and emotional disorder, which are increasingly playing larger roles in causing wasting thirst, or diabetes.

Effects of garlic powder supplementation on blood lipid profile and antioxidant system were investigated in rats with and without swimming exercise. Sprague-Dawley rats of four experimental groups were fed for 4 weeks diets containing $15\%$ beef tallow and $1\%$ cholesterol; control without garlic and exercise, Go with $2\%$ garlic alone, Ex with exercise alone, GoEx with $2\%$ garlic and exercise. Rats were trained 40 min a days a days a week. Group Ex and GoEx showed significant lowering in body weight gain and fat accumulation. In Go, Ex and GoEx, plasm TG and LDL-C were lower and HDL-C was higher, although not significantly, compared to levels in control. Total cholesterol was significantly reduced in group Go, and Ex and GoEx were lower than control. The total/HDL cholesterol ratio was also found to be significantly different, decreasing the ratios in Go, Ex and GoEx. The hepatic TBARS increased significantly in group Ex $(51.7{\pm}3.43nM/g\;liver)$, while TBARS in Go and GoEx were low $(35.68{\pm}3.61,\;39.30{\pm}5.55nM/g\;liver)$ and similar to control's one. The activity of hepatic SOD in Go and GoEx tended higher than control and Ex without garlic. The hepatic catalase showed significantly the highest activity in Go. Activity of GSH-px was significantly low in Ex with $0.14{\pm}0.03$ unit/mg protein, and control, Go and GoEx had higher activities of $0.23{\pm}0.08,\;0.20{\pm}0.07,\;0.22{\pm}0.01\;unit/mg$ protein, respectively. Lower activities of antioxidant enzymes in Ex are likely to associated with the highest level of TBARS. It seems that a decrease in TBARS in GoEx relative to Ex was related to the increase in GSHpx and SOD with garlic supplemented, which led to compensate the oxidative stress from exercise. The results suggests that exercise or garlic supplement exerts blood lipid attenuating effect. In adition, garlic supplementation could strengthen the antioxidant potential against exercise-induced oxidants, partly by modulating oxidant enzyme activity. These effects of garlic may make it a beneficial agent on CVD.

BACKGROUND/OBJECTIVES: We investigated the effects of a combination of grape pomace (Vitis labrusca, Campbell Early) and Omija fruit (Schizandra chinensis, Baillon) ethanol extracts on lipid metabolism and antioxidant defense system in diet-induced obese mice. MATERIALS/METHODS: Forty male C57BL/6J mice were divided into four groups and fed high-fat diet (control group, CON) or high-fat diet added 0.5% grape pomace extract (GPE), 0.05% Omija fruit extract (OFE) or 0.5% GPE plus 0.05% OFE (GPE+OFE) for 12 weeks. RESULTS: In contrast to the GPE- or OFE-supplemented groups, the GPE+OFE group showed significantly lower body weight and white adipose tissue weights than the CON group. Moreover, GPE+OFE supplementation significantly decreased plasma total cholesterol and increased the plasma HDL-cholesterol/total-cholesterol ratio (HTR) compared to the control diet. The hepatic triglyceride level was significantly lower in the GPE+OFE and GPE groups by increasing ${\beta}$-oxidation and decreasing lipogenic enzyme compared to the CON group. Furthermore, GPE+OFE supplementation significantly increased antioxidant enzyme activities with a simultaneous decrease in liver $H_2O_2$ content compared to the control diet. CONCLUSIONS: Together our results suggest that supplementation with the GPE+OFE mixture may be more effective in improving adiposity, lipid metabolism and oxidative stress in high-fat diet-fed mice than those with GPE and OFE alone.

The purpose of this study was to analyze and evaluate dietary intake between with and without hypertension. Study subjects were more than 30 years old adults (n = 3,806) who participated in the 2001 Korea National Health and Nutrition Examination Survey. People who have 'self-recognition about hypertension' and 'having diet for hypertension' were excluded. Using the WHO standard, subjects were divided into the hypertensive group (SBP> 140, DBP> 90) and the normal group (SBP< 140, DBP< 90). The Body Mass Index (BMI) and the Waist-Hip Ratio (WHR) of a hypertensive group were higher than those of a normal group (p < 0.01). The distribution of the subjects for smoking, alcohol consumption, exercise, stress, preference of salty food were not significantly different between a normal group and a hypertensive group (p>0.05). Dietary intakes were investigated by the 24-hour recall method. When food and dish intakes analyzed by sociodemographic factors, normal group consumed more fruits than those of a hypertensive group. Statistical significant were shown at female group, residences in metropolitan area and having elementary school education (p<0.05). Hypertensive group consumed more alcoholic beverages than those of a normal group at 'age 39-39', 'aged 50-64', 'high economic status', 'low economic status' and 'residences in metropolitan' (p<0.05) The amount of intakes for fat, potassium, thiamin, vitamin C and alcohol were significantly different between the normal group and the hypertensive group (p<0.05). The highest score of the Dietary diversity score (DDS) was 4 in both normal group and hypertensive group. Normal group showed high Nutrition Density (ND) of vitamin C and hypertensive group showed high ND of sodium. In summary, these results showed that significant difference for people with hypertension were intakes of fruits, alcohol, thiamin, vitamin C. And these results differed by sociodemographic groups. Therefore, the differential approach in each group is demanded for prevention and control of the hypertension.
