This study was performed to investigate the effects of Korean native plant diets on lipid and cadmium (Cd) metabolisms and also antioxidative enzyme activities in rats. Seventy male Sprague-Dawley rats weighing 210.3$\pm$2.7g were blocked into ten groups according to body weight. Rats were raised for four weeks with diets containing 0 or 0.04%(w/w) cadmium chloride and 5%(w/w) plant powder-Ssook(Artemisia princeps var. orientalis HARA), Chamchwi(Aster scaber THUNB), Gomchwi(Lingularia fischeri TUBCZ). or Solbeerum (Portulaca oleracea LINNE). Food intake, weight gain, food efficiency ratio, and weights of liver, kidney, spleen and epididymal fat were significantly lower in Cd-exposed groups, food efficiency ratio, and weights of liver, kidney, spleen and epididymal fat were significanlty lower in Cd-exposed groups. Plasma total lipid level, liver total lipid, cholesterol and triglycerde concentrations, and fecal total lipid, cholesterol and triglyceride excretions were decreased by Cd administration. Total lipid and triglyceride concentration in plasma and liver were lower in Chamchwi groups together with increased fecal total lipid and triglyceride excretions. Cholesterol concentration in plasma and liver were lower in Gomchwi groups with increased fecal cholesterol excretions. Activities of red-blood-cell superoxide dismutase(SOD), and liver catalase, SOD and glutathione peroxidase (GSH-px) were decreased significantly by Cd administration. Thiobarbituric acid reactive substance(TBARS) concentrations of plasma and liver were increased by Cd administration. Thiobarbituric acid reactive substance(TBARS) concentration of plasma and liver were increased by Cd administration. Administration of plant diets decreased plasma and liver catalase, SOD and GSH-px activities in Cd-free diet groups and increased them in Cd-administered groups. Plasma and liver TBARS concentrations were decreased in animals fed plant diets, with Chamchwi showing the most effective antioxidative capacity. The concentration of Cd accumulated in blood and tissue decreased in Cd-exposed groups fed plant diets. Liver Cd concentration were lower in the Chamchwi and Gomchwi groups, and kidney Cd levels were lower in the Ssook and Chamchwi groups. Among them, Chamchwi was the most effective in Cd detoxification. In conclusion, Chamchwi and Gomchwi were effective in lowering tissue lipid levels, with Chamchwi having the greatest antioxidative and detoxifying effects.

This study was conducted to investigate the supplementary effects of Suwon 464 developed by Rural Development Administration, which has over two times of dietary fiber content compared with normal rice (Ilpum), on lipid metabolism in diabetic mice. We supplied 5 kinds of experimental diets (com starch diet as a control (CO), Ilpum polished rice diet (IP), Ilpum brown rice diet (IB), polished rice diet (SP) and brown rice diet (SB) of Suwon 464) to diabetic mice for 8 weeks, after analyzing dietary fiber contents of 5 experimental diets. Diet intake, body weight, organ weights, and lipids levels of serum, liver and feces were measured. The dietary fiber contents in CO, IP, IB, SP, and SB diets were 1.0, 1.2, l.4, 1.4, and 2.0% respectively. Body weight and liver and epididymal fat pad weights were lower in SB group than the other groups though there was no significant difference in diet intake among experimental groups. The concentrations of serum triglyceride was lower in SP and SB groups than CO and IP groups. The levels of hepatic total lipid and total cholesterol were significantly lower in SP and SB groups than CO group, and the level of hepatic triglyceride was lower in IB, SP and SB groups than CO group. The levels of total lipid and triglyceride excreted in feces were higher in IB, SP and SB, and the level of total cholesterol in feces was higher in SP and SB groups than CO group. These results suggested that the high dietary fiber rice (Suwon 464) decrease the triglyceride or total cholesterol concentrations of serum and liver by increasing of fecal lipid excretion in diabetic mice.

The effects of the MeOH and water extracts from the marine algae Pelvetia siliquosa were evaluated on hyperlipidemic rats induced by cholesterol rich diet or poloxamer-407. The MeOH and water extracts, when administered orally for 3 consecutive days in hyperlipidemic rats induced by poloxamer-407 (1 ml of 30%), were found to cause a significant decrease in plasma cholesterol and triglyceride concentrations. Both extracts also showed a significant inhibition of serum total cholesterol and triglyceride level in rats treated with cholesterol rich diet. HDL-cholesterol, however, was increased significantly.

The effect of habitual alcohol consumption on the nutrient intake. body weight and serum values were studied in 194 upper middle class men aged 35-55yr. living in Seoul. Each subject was interviewed to get information of alcohol and nutrients intake. Blood samples were taken. Mean values for each variable were compared by fertile of alcohol intake. The average alcohol consumption of the subject was 32.2g/day. Most of times foods were taken along with drinks. The subjects preferred food items such as meat. fish, nuts. dry fishes when they drink. High alcohol consumers had a significantly higher intake of calorie. protein, fat. Fe, and riboflavin compared to nondrinkers and moderate drinkers. Body weight was significantly higher in high alcohol drinkers followed by moderate and nondrinker groups. They also showed the higher serum values of triglyceride and r-GTP. High alcohol consumption resulted in an increased intakes of most nutrients especially calorie and fat which leads to higher body weight and higher serum concentrations of triglyceride and r-GTP. Therefore it seems that heavy alcohol drinkers are more prone to obesity and related chronic diseases.

The objective of this study was to examine the effects of seven dietary oils on the serum lipid patterns of rats. Seventy weanling Wistar Kyoto rats were divided into seven groups of ten rats each. Walnut oil (rich in PUFA), wheat germ oil (rich in PUFA), corn oil (rich in PUFA), canola oil (rich in monounsaturated fatty acids), fish oil (rich in PUFA), primrose oil (rich in PUFA), and palm oil (rich in saturated fatty acids) were employed for 21 days. Serum total cholesterol concentrations for rats fed palm oil, walnut oil, and wheat germ oil were significantly higher than were concentrations for rats receiving corn oil. fish oil, and primrose oil. The mean serum LDL cholesterol values for rats fed fish oil, primrose oil, and corn oil were significantly lower than those for rats fed walnut oil, wheat germ oil, canola oil, and palm oil. HDL cholesterol concentrations were the highest when wheat germ oil was fed and the lowest when fish oil was fed. The feeding of wheat germ oil and palm oil to rats resulted in considerably higher serum triglyceride levels than did all other treatments. The feeding of wheat germ oil to rats resulted in considerably higher serum phospholipid levels. Serum phospholipid concentrations were significantly lower in rats fed the canola oil, fish oil, ,and primrose oil diets, when compared to concentrations achieved with the feeding of walnut oil, wheat germ oil, corn oil, and palm oil. Palm oil, which has a high ratio of saturated to polyunsaturated fatty acids, resulted in the highest serum total cholesterol and highest LDL cholesterol levels, while fish oil, primrose oil, and corn oil produced the lowest total cholesterol and LDL cholesterol. Wheat germ oil produced the highest values for HDL cholesterol, triglycerides, and phospholipids. In general, feeding oils rich in polyunsaturated fatty acids produced more favorable responses than feeding oils containing large amounts of monounsaturated or saturated fatty acids.

Leptin, the product of the ob gene, is a small peptide molecule synthesized by white adipocytes with an important role in the regulation of body fat and food intake. Based on the evidence that synthesis of leptin is regulated by female sex hormone, estrogen, this present study was investigated whether sex hormone precursor DHEA, can regulate obese gene expression in lean and genetically obese (ob/ob) mice. Antiobesity activity of DHEA was evaluated by determining body weight, food consumption, epididymal fat weight and serum levels of cholesterol and triglyceride in ICR, C57BL/6J, and ob/ob mice. The treatment of C57BL/6J lean and obese mice with a diet containing 0.3% and 0.6% DHEA resulted in lowered rates of weight gain in comparison to non-treated mice, although much greater response was found in the obese mice. All other concentrations of DHEA (0.015%, 0.06%, 0.15%, 0.3%) except the highest one(0.6%) showed no significant effects on weight gain in ICR mice. Food consumption was significantly decreased in all mice treated with 0.6% DHEA, whereas it was not decreased in ICR mice at lower concentrations than 0.6% DHEA. DHEA decreased significantly epididymal adipose tissue weight and serum triglyceride levels dose dependently in lean and obese mice. However serum cholesterol levels were decreased at lower concentrations than 0.15% DHEA and increased at concentrations of 0.3% and 0.6% DHEA in lean and obese mice. These increases in serum cholestrol levels at high concentrations of DHEA might result from the fact that DHEA has a cholesterol moiety thereby interfered the assay system. As an approach to elucidate the mechanism for antiobesity activity of DHEA, we examined mRNA levels of obese gene in the adipocyte and obese gene product (leptin) in the serum. The results showed that DHEA did not affect obese gene expression in ICR and C57BL/6J mice. Therefore, we concluded that antiobesity activity of DHEA was not modulated by obese gene expression.
