The purpose of this study was to analyze and consumption patterns diet/low-calorie food. Ubjects were 353 adult women aged 20s~50s. Ubjects were divided into three groups according to body mass index (BMI): Normal group (BMI>23.0), overweight group (23.0${\leq}$BMI<25.0), and obesity group (BMI${\geq}$25.0). This study collected all information by self-administrated questionnaires. The SPSS version 21.0 was used for analysis of data. The obesity group lower education level (p<0.001), higher age (p<0.001) and higher income (p<0.001) than normal group. However, score of health status was highest in normal group (p<0.001). Proportion of obesity group pill type diet/low-calorie (p<0.034), drug (diuretic, appetite suppressant and riental medicine) (p<0.001), and cosmetic surgery (p<0.001). The main reason for consumption of diet/low-calorie was control without starving (28.0%). Obese group emphasized manufacturer, ingredient and reputation, whereas the normal group emphasized price and expected effectiveness (p<0.001).

The purpose of this study was to investigate the effects of garlic diet on blood coagulation in cholesterol-fed rats. 36 male rats were divided into six groups and fed experimental diet for three weeks. Two-levels (2% and 4%) of fresh and boiled garlic were supplemented to the stock diet with 2% cholesterol and 0.25% bile salt for the experimental diet. After the rats fed with experimental diets during 3 weeks, the whole blood coagulation time, the content of plasma fibrinogen, the fibrinolytic activity and the prothrombin time were measured. The results are summarized as follows; 1. Garlic diet have no influence on body weight and food consumption in rats. 2. In the case of cholesterol-fed group, the whole blood coagulation time was decreased 24.3% compared with the normal group(A). But garlic diet group(C) was similar to the normal group(A) and groupD-F was increased 4.9-11.5%. 3. The content of plasma fibrinogen of cholesterol-fed group was higher 114.5% than that of normal gropu(A). In the garlic diets(C-F) the contents of plasma fibrinogen were increased 33.1-63.8%. 4. The fibrinolytic activity of cholesterol diet was decreased 16.2% compared with the normal group(A) but was increased 10.9-44.5% compared to the garlic diets(C-F). 5. The prothrombin time of cholesterol-fed group was decreased 8.9% compared with normal group(A) but was increased 8.0-46.3% in garlic diets(C-F). As mentioned above, the garlic diets increased whole blood coagulation time, prothrombin time and fibrinolytic activity and decreased the content of fibrinogen. For that reason it is thought that the garlic diets have a anticoagulation effect regulating the fibrinogen synthesis in liver.

Obesity can be defined as a metabolic disease due to an increased fat accumulation in the body caused by an imbalance of calorie intake and output The prevalence of obesity has increased substantially over the past 2-3 decades in developed and developing countries. The health impact of weight gain is so marked that obesity has now been classified as a major global public health problem In order to investigate the effect of diet conversion and oral administration of Platycodon grandiflorum extracts on the treatment of obesity, male Spraque-Dawley rats were divided into four groups: a group converted to normal diet (Control group), a group maintained high fat (30%) diet (H), and two groups with Platycodon grandiflorum extract added to the previously mentioned two groups. All animals were fed high fat diet for 7 weeks to induce the obesity. Then they were divided as mentioned above. Animals were fed experimental diet and Platycodon grandiflorum extract (150 mg/ml/rat/day) for 7 weeks. Body weight, adipose tissue weight (subcutaneous, epididymal, peritoneal fat pads) and serum lipids (total cholesterol and triglyceride) showed some differences among groups. The Platycodon grandiflorum feeding markedly decreased both body weight and adipose tissue weight in control group compared to H, high fat diet maintaining, group. Platycodon grandiflorum extracts significantly decreased the concentrations of serum lipids compared to H group. Fat cell numbers and sizes were significantly reduced in the oriental medicinal herb extract administrated group. Increased fatty acid binding protein (FABP) expression in high fat diet group was decreased by the dietary conversion to normal diet and the oral administration of Platycodon glandiflorum extracts. In contrast, there was no significant effect on FABP expression in the high fat maintenance group. In this study, the conversion from high fat diet to low fat or normal diet had a beneficial effect on body weight loss and serum lipid profiles. Dietary Platycodon glandiflorum extracts had an additive beneficial effect on the prevention and treatment of obesity.

Purpose: To elucidate the effects of the irradiation and calcium-deficient diet on expression of interleukin (IL)-1 during tooth formation of rat molar. Materials and Methods: The pregnant three-week-old Spague-Dawley rats were used for the study. The control group was non-irradiation/normal diet group, and the experimental groups were irradiation/normal diet group and irradiation/calcium-deficient diet group. The abdomen of the rats on the 9th day of pregnancy were irradiated with single dose of 350 cGy, The rat pups were sacrificed on the 14th day after delivery and the maxillae tooth germs were taken. The specimen were prepared to make sections for light microscopy, and some of tissue sections were stained immunohistochemically with anti-IL-l antibody. Results: In the irradiation/normal diet group, dental follicle showed fewer blood vessels, mononuclear cells, and fusions of mononuclear cells than in non-irradiation/normal diet group. Alveolar bone showed a few osteoblasts and osteoclasts. Periodontal ligament showed collagen fibers and fibroblasts with irregularity. Weak immunoreactivity for IL-l was shown in dental follicle, alveolar bone, and periodontal ligament. In the irradiation/calcium-deficient diet group, dental follicle showed sparse cellularity. Alveolar bone showed diminished number of osteoblasts. Periodontal ligament showed irregular collagen fibers and atrophy of cementoblasts and fibroblasts. No immunoreactivity for IL-1 was shown in dental follicle, alveolar bone, and periodontal ligament. Conclusion: Irradiation and calcium-deficient diet seems to cause disturbance of the expression of interleukin-l during tooth formation of rat molar.

The purpose of this study was to investigate the effects of vitamin E on the oxidative damage and glomerular filteration rates(GFR) of kidney in streptozotocin(STZ) induced diabetic rats. Sprague-Dawley male rats weihing 100$\pm$10gm were randomly assigned to one normal and three STZ-induced diabetic groups which were subdivided into vitamin E free diet(DM-0E group)40mg vitamin E per kg diet(DM-40E group) and 400mg vitamin E per kg diet (DM-400E group), Vitamin E level of normal group was 40mg per kg diet. diabetes was experimentally induced by intravenous injection of 55mg/kg of body weight of STZ in citrate buffer(pH 4.3) after 4 weeks feeding of experimental diets. Animals were sacrificed at the 6th day of diabetic states. Activities of xanthine oxidase(XOD) in DM-0E DM-40 and DM-400E groups were significantly increased by 133%, 110%, and 74% respectively compared to normal group. The contents of microsomal superoxide radical(O2) in kidney were 106% and 119% higher of DM-0E and DM-40E groups than normal group respectively but that of DM-400E group was similar to normal group. The level of urnary microalbumin in DM-0E group was increased as 5 times much as normal group at the 6th day. Those of DM-40E and DM-400E groups were decreased to 16% and 36% respectively compared to DM-0E group. The content of urinary $\beta$2-microglobulin in DM-0E DM-40E and DM-400E group were increased by 268%, 181% and 163% respectively compared to normal group. GFR in DM-0E and DM-40E were significantly increased but was nor significantly different from DM-400E groups compared to normal group. In conclusion the supplementation of dietary vitamin E reduced peroxidative damage of renal glomerular and renal dysfunction in diabetic rats.

Korean safflower seed has been known to have healing effects on both bone fracture and osteoporosis. On the base of such a notice, this experiment was carried out to explore the effects of safflower seed on bone formation and bone repair. The toxicity test and the effect of Korean safflower seed were evaluated with 60 rats, 3-month old. Forty Sprague-Dawley rats composed of 20 male and 20 female were underwent unilateral tibial defect and then fastened with unilateral fixators. The operated rats were divided into two groups depending on the composition of diet, such as positive control group fed normal diet(C-OP group) and safflower seed group fed 30% of safflower seed diet and 70% of normal diet(S-OP group). Another 20 rats without operation were maintained, each 10 rats were fed either normal diet or 30% of safflower seed diet and 70% of normal diet, and observed the toxicity of safflower seed by measuring weight and urine parameters. Postoperative radiography were taken once in 2 weeks to evaluate callus formation for operated groups and blood collection via heart puncture were carried out once in 3 weeks for 3 groups. The concentration of Ca and Pi in serum were measured using both auto Kit and $^{31}$ P Nuclear Magnetic Resonance(NMR). At present study, no toxic effect was observed from both weight increment and urine index after feeding the safflower seed diet. The comparison of the radiography between C-OP and S-OP group were showed that the safflower seed diet appeared to stimulate the formation of callus in the rat. The ratio of Ca/P in serum was low in S-OP group compared to C-OP group with the auto Kit, but there were no significant differences between two groups (p < 0.05). In addition, the variations of Pi values in NMR examination were also confirmed based on the result of auto Kit. In conclusion, this study implied that safflower seed might influence to bone formation and shorten the periods of remedy by stimulating the calcification of bone

This study was performed to investigate the effect of a raw diet (RD) on blood glucose and immune function in non-diabetic (normal) and streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were assigned to four groups (normal control, normal RD, diabetic control and diabetic RD). The control groups and the RD groups were fed an AIN-diet and RD for four weeks, respectively. Weight gain was statistically lower in the RD groups than in the controls. Fasting plasma glucose was significantly lower in the diabetic RD group than in the diabetic control group. The $CD4^+$ T-cell population was higher along with the $CD4^+/CD8^+$ ratio of the mesenteric lymph nodes in the normal RD group compared to the other groups. It can be concluded that RD may reduce the plasma fasting glucose concentration in diabetic rats and improve mesenteric lymph node immune function in normal rats.

The effect of lycopene supplementation on the antioxidant system was investigated by analyzing lipid peroxide levels, glutathione contents, and antioxidant enzyme activities in Mongolian gerbils fed a high fat diet. Gerbils were fed on each experimental diet for 6 weeks; normal diet (NC), normal diet with 0.05% lycopene (NL), high fat diet (HF), and a high fat diet with 0.05% lycopene (HFL). Dietary supplementation of lycopene increased hepatic lycopene level in gerbils fed a normal or high fat diet (P < 0.05). Liver and erythrocyte concentrations of lipid peroxide increased in gerbils fed a high fat diet, whereas lycopene supplementation decreased liver and erythrocyte concentrations of lipid peroxide (P < 0.05). Hepatic total glutathione content was higher in the NL group than that in the NC group (P < 0.05). Total antioxidant status in plasma increased following lycopene supplementation compared with that of the non-lycopene supplemented groups (P < 0.05). Hepatic catalase activity increased following dietary lycopene supplementation (P < 0.05). Superoxide dismutase activity in liver remained unchanged with lycopene supplementation, but erythrocyte superoxide dismutase activity increased in NL group compared with NC group (P < 0.05). Glutathione-S-transferase activity increased in the NL group compared to NC group (P < 0.05). Liver and erythrocyte glutathione peroxidase activity increased significantly in the NL group compared to that in the HF group (P < 0.05). Liver glutathione reductase activity was higher in the NL group than that in the NC group (P < 0.05). These results suggest that lycopene supplementation may be efficient for preventing chronic diseases induced by oxidative stress related to high fat diet.

The effect of ginseng components on the potassium depleted cardiomyopathic rat heart was investigated. In the perfused heart experiment using Langendorff apparatus, the deterioration rate of contriactile force of potassium depleted rat heart (low potassium diet group) was faster than that of normal rat heart and ginseng components showed the ability to slow the deterioration rate of potassium depleted hearts. Both sialic acid contents in carcolemmal ghost and sialyltransferase activity of 40,000 * g subcellular fraction prepared from cardiac ventricular tissue of low potassium diet group were significantly decreased compared to those of normal group. The decrease of the sialic acid content and sialyltransferase activity in sarcolemma of low potassium diet group was inhibited when ginseng was concomitantly administered. Calcium uptake of sarcoplasmic reticulum prepared from low potassium diet group was significantly greaterthan that of normal group. Ginseng extract or total saponin showed the tendency to inhibit the increase of cacium uptake.
