    This study examined the effect of dietary lipids and guar gum on lipid metabolism in ovariectomized rats. The experimental animals received ovarietomy (OVX). Lipids sources were divided into 3 groups (soybean oil(SB), beef tallow(BT)) and fish oil(FO)) and guar gum was supplemented to each lipid diet (SBG, BTG, FOG). Experimental diets were fed to therats for 16 weeks. Serum triglyceride (TG) levels were higher in the BT group and lower in the FO group as compared to the SB group .Serum total cholesterol (Tc) and HDL-C levels were lower in the FO group as compared to the SB group. Serum LDL-C and phospholipid levels were lower in the FO group as compared to the SB group. Serum lipids levels were lowered by guar gum supplement. Serum SFA(saturated fatty acids) contents were not significantly influenced by dietary lipids and guar gum. Serum MUFA(monounsaturated fatty acids) contents were the lowest in the SB group. Fecal weight was highest in the beef tallow group and lowest in the fish oil group. Fecal weight was increased by guar gum supplement in all lipid groups. Total bile acid content in feces was increased by guar gum supplement in the soybean oil and beef tallow groups. The endothelial cells of the beef tallow group changed from a flat shape to distorted round and enlarged shapes. The subendothelial layer was the thickness the thickest in the beef tallow group ; the interspace between elastic lamina was widened and elastic lamina was straightened and partly disrupted . The fish oil group showed more porminient endothelial cells and subendothelial layer. Internal elastic membrane and elastic lamina exhibited regularly wavy shapes. Guar gum supplement showed positive effects in all lipids groups. Based on the above results , it is suggested that beef tallow increased serum TG levels and injured the wall of the aorta. On the other hand, fish oil , which decreased serum lipid levels, has a positive effect on the walls of the aorta. Guar gum protects the aorta from injury by reducing the serum lipid levels. Therefore, it is suggested that soybean oil and beef tallow consumed with guar gum is beneficial.

    Serum and liver lipid levels and fatty acid composition of liver phospolipids (PL) were investigated in 36 rats which consumed either one of five different dietary fats or a high carbohydrate diet for 4 weeks. As the sources of five dietary fats, concentrated cicosapentaenoic acid(EPA), fish oil (FO), perilla oil(PO), corn oil(CO) and beef tallow (BT) were provided to the rats. As a control group, cron starch (CS) replaced dietary fat. The FO group showed lower serum total cholesterol (TC), high density lipiprotein cholesterol(HDL-C) and serum PL levels than those of the CO group(p

    We investigated the effects of vitamin E supplementation on lipid peroxidation and on the activities of antioxidative enzymes in kidney of KK mice of various age and duration of diabetes. Weaned KK mice were fed high fat a diet containing 20% corn oil(wt/wt), and were sacrificed at 4, 6, and 9 months of age. The high vitamin E diet consisted of the high fat diet supplemented with an excessive amount of dl- $\alpha$ -tocopheryl acetate (2080 IU/kg diet) . In the diabetic groups, we found an increase in lipofuscin and decrease in antioxidative enzyme activities with aging. Treatment with vitamin E did not modify the level of fasting blood glucose. However, a significant decrease in lipofuscin and increase in antioxidative enzyme acitvities were observed in diabetic mice.

    The purpose of this research was to investigate the effects of caffeine and calcium levels on calcium utilization in female rats of different ages. Calcium utilization was compared in female rats of different age( 4 weeks and 12 months) fed various levels of caffeine(0 and 7 mg/100g body weight) and calcium (50, 100 and 200% of requirement) for 3 weeks. Feed intake of the caffeine groups were lower than that of the no-caffeine groups. body weight gain was lowest in the high-caffeine and low-calcium group. Serum calcium levels of young rats were higher than those of adult rats. There were no significant differences in tibial calcium content among the caffeine and calcium -groups. Fecal calcium excretion increased as the level of dietary calcium was increased. Urinary calcium excretion increased as the levels of caffeine and dietary calcium were increased. With increasing levels of dietary calcium , daily calcium retention was accelerated, but apparent calcium absorbability was diminished. The results of this study suggest that caffeine consumption promotes urinary calcium excretion. However, increase in dietary calcium resulted in higher calcium retention . These findings indicate that high caffeine consumption may increase dietary calcium requirements. Therefore, it could be suggested that the supplementation of dietary calcium may counteract the negative effect of caffeine intake on calcium utilization.

    This study was designed to determine blood glucose responses to some cereals produced in Korea. The levels of blood glucose were measured over 2 hours after feeding healthy vounteers with 50g carbohydrate portions. The glycemic index(GI)k and glycemic index-rice(GI-rice) of a food has been defined as : GI=mean of (blood glucose response area of test food/ blood glucose response area of glucose taken by the same indicidual) $\times$ 100 and GI-rice=mean of (blood glucose response area of test food/blood glucose response area of rice taken by the same individual) $\times$ 100. The area under the curve is taken to be the area above the fasting value calculated geometrically from blood glucose increments. The GI of barely to glucose as the standard(57 $\pm$ 7) was significantly (p $\pm$ 8) was significantly (p $\pm$ 6 for barley, 79 $\pm$ 5 for buckwheat, 85 $\pm$ 6 for foxtail millet, 90 $\pm$ 12 for unpolished rice, 100 $\pm$ 0 for rice, 102 $\pm$ 7 for glutinous rice, 106 $\pm$ 6 for unpolished glutinous rice, 115 $\pm$ 13 for glutinous millet, 116 $\pm$ 13 fro job's tear, and 122 $\pm$ 4 glutinous sorghum.

    Cigarette smoking is a major risk factor of atherosclerosis and has been reported to contain an abundance of free radical species which could be expected to deplete antioxidants such as vitamin C . The present study was designed to investigate the relationship between smoking, plasma lipid and lipoprotein concentration, and plasma vitamin C level. Fifty-five healthy male smokers and 32 non-smokers were investigated in the study. Mean age, body weight , BMI and blood pressure made no differences in both smokers and non-smokers. Significantly, smokers has higher plasma total cholesterol and LDL-C , and lower HDL-C /LDL-C ratio compared with non-smokers. Plasma level of thiobartiturin acid reactive substances(TBARS), indicator of lipid peroxidation and increased susceptibility of LDL towards lipid perosidation, were elevated in smokers(p

    Iodine-rich seaweed soup has been traditionally supplied to postpartum women in Korea. This dietary habit might introduce over-intake of iodine above the recommended requirements, and might provoke postpartum thyroid dysfunction. Although the response to excess iodine intake is highly variable, goiter, hyperthyroidism, hypothyroidism, and thyroiditis could follow the daily intake of 1,500 $\mu\textrm{g}$ of iodine. A few studies are available concerning iodine toxicity in Korea. The purpose of this study was to investigate the relationships between the dietary intake of iodine and thyroid function change as well as the incidence of postpartum thyroiditis. One hundred and thirty-seven postpartum women who had experienced normal deliveries were studied. Dietary intake of iodine and excretion concentration of iodine in breast milk and maternal urine were measured . Serum T $_3$ , T $_4$ , TSH, anti-thyroglobulin antibody, and anti-microsomal antibody were anlayzed 1 week before delivery and 1, 6, 12, and24 weeks after delivery. Iodine intake was analyzed by one-to-one interviews using 24-hr recall and a food frequncy questionnaire. The result showed that the intake of dietary iodine before delivery and 1 and24 weeks after delivery were 483 $\mu\textrm{g}$ /day, 3367 $\mu\textrm{g}$ /day, and 1069 $\mu\textrm{g}$ /day, respectively. The concentration of iodine in urine at the first week after delivery was 63 $\mu\textrm{g}$ /dL, and 23.9 $\mu\textrm{g}$ /dL in breast milk . The levels of serum T $_3$ and T $_4$ before delivery were 2.01ng/mL and 11.49 $\mu\textrm{g}$ U/dL, respectively, showing that the levels were gradually dropping to normal values after delivery. Positive serum anti-thyroglobulin antibody and anti-microsomal antibody appeared in 3 cases. After a 24 week follow-up period , 6 women(10.3%) experienced cases of postpartum thyroiditis, 5 of which were cases of hyperthyroidism and one of which was a case of hypothyroidism. These figures of postpartum thyroiditis are similar to those of other countries.

    This study was performed from March to June 1994 in ANsung Medical Center. We investigated serum components of 78 diabetics in the center, in addition to the nutrient intake status and anthrophometric status of 60 diabetics among them. We separated the latter into 2 groups(ⅰ) less tan 5 years of diabetic duration and ⅱ) more than 6 years of diabetic duration) and analyzed the clinical characteristics of each group. The results are as follows : \circled1 The average ages of male and female subjects were 57.1 and 58.9 years, respectively. The average diabetic duration of male subjects was 4.8 years and that of female subjects was 5.9 . The major occupational field of both male and female subjects was agriculture(33.3%, 36.1%). 50% of male and 75% of female subject's monthly incomes were less than 600, 000 won and 75% of male and 94.4% of female subjects had weekly food expense less than 40, 000 won. The nutrient intake status of the subjects was lower than RDA on the whole. There was no big differences between 2 the male groups of different diabetic duration , but calorie, protein , fat carbohydrate, phosphorus, iron and Vit B $_1$ intakes of the above 6 year female group were appearently higher than those of the under 5 year female group (p $_1$ , Vit B $_2$ , and niacin were observed. Furthermore, the longer the diabetic duration in females , the more intakes of energy and nutrients, except Vit C were observed. Fasting blood glucose levels were 155mg/dl and 164mg/dl and Postprandial glucose levels were 242mg/dl and 247mg/dl for males and females respectively. Hb of both males and females , and Ht of males met the lower limit of normal status, The serum TG level was higher than normal , so that they seemed to suffer from hyperlipidemia ; their high HbAIC status indicated that the management of diabetes mellitus was poor. The total protein level of female subject was higher when compared with that of males(p
