The present study has been undertaken to investigate the effects of crude ginseng extract added to food on the lipid composition in serum of rats fed lard and alcohol. Thirty-five males of Sprague-Dawley strains weighed about 130 g were divided into 7 group, each group receiving a different diet for 10 weeks ; i.e. basal diet plus 15% lard, basal diet plus 5% alcohol, basal diet plus 0.5% crude ginseng extract, basal diet plus 15% lard and 0.5% crude ginseng extract. Determinations were carried out on the net weight gain, food efficiency ratio, weight of organs, triglyceride, total cholesterol, HDL-cholesterol, free cholesterol. The results obtained were as follows : 1. Rats given feed containing lard and alcohol showed significant decrease in net weight gain, but crude ginseng extract caused an increase in food efficiency ratio. 2. Lard supplementation group showed increase in the weight of liver, kidney, spleen, but another groups did not. 3. The contents ratio of triglyceride, total cholesterol in serum of lard-fed group showed significant increase compared to controls and but the simultaneous supplementation of crude ginseng extract and lard decreased significantly than those of lard-fed group. 4. The contents of free-cholesterol and ester cholesterol in serum of the simultaneous supplementation of crude ginseng extract group decreased as compared with the lard single fed group. 5. Crude ginseng extract single-fed groups. 6. The ratio of contents of VLDL, LDL-cholesterol in serum was significantly high in the only lard containing group and alcohol group, the crude ginseng extract supplemented group was showed lower tendency than only lard and alcohol group. The above results suggest that crude ginseng extract would prevent the metabolic disease by improving hyperlipoidemia.

This study was designed to investigate the effect of dietary vitamin E levels on lipid metabolism in caffeine-fed rats. Male Sprague-Dawley rats were fed on diet containing one of three levels of vitamin E(37.5, 750, or 1,500mg/kg diet0 which was with or without 0.3% caffeine. The rats were sacrificed after 5 and 10 weeks of the feed periods. Results obtained from this study were as follows ; Net weight gain, feed intake and FER in the caffeine added groups were significantly decreased as compared to those of only vitamin E fed group. Liver and kidney weights tended to increase in the caffeine added groups, but spleen and heart weights were not affected. Total lipid contents in serum and liver tended to decrease as dietary vitamin E became increasing and caffeine diet adding. Serum total cholesterol content tended to increase in the caffeine added group. But, liver cholesterol content were decreased. And the higher the dietary vitamin E level became, the lower serum and liver cholesterol contents were. Serum and liver triglyceride contents were significantly lower in the caffeine added groups than in the only vitamin E fed groups. The degree of decrease was more evident as dietary vitamin E level became more increasing. Serum aminotransferase activity was not affected in all experimental groups.

The purpose of the present study was to evaluate the effects of red pepper seeds powder on lipid metabolism in rats fed high fat high cholesterol diet. Rats were divided into five experimental groups: normal diet group, high fat high cholesterol diet group, high fat high cholesterol diet with 5% red pepper seeds powder supplemented group (SA group), high fat high cholesterol diet with 10% red pepper seeds powder supplemented group (SB group) and high fat high cholesterol diet with 15% red peeper seeds powder supplemented group (SC group). The serum triglyceride (TG) and cholesterol contents, and LDL-cholesterol and atherogenic index (AI) of the red pepper seed powder supplemented groups were significantly decreased compared to the HF group. The serum HDL-cholesterol contents of the red pepper seed powder supplemented groups were increased compared to the HF group. However, there was no significant difference in the serum HDL-cholesterol among all experimental groups. The hepatic TG and cholesterol contents of the red pepper seed powder supplemented groups were significantly decreased compared to the HF group. The fecal total cholesterol and triglyceride contents of the red pepper seeds powder supplemented groups were significantly increased compared to the HF group. These results suggest that supplementation of red pepper seed powder may have a pronounced impact on markers of lipid metabolism in serum and liver of rats fed high fat high cholesterol diets.

Objects. There was an increase in obese population due to eating habits resulted in modernization of lifestyle and the change of the tendency to conduct the physical activity, in order words, the reduction in the range of kinetic energy. Obesity is viewed as a major risk factor for serious health problems, including heart disease, high blood pressure, stroke, diabetes, and certain forms of cancer as well as for psychological and social problems owing to our fat-phobic society. In the present study, we investigate the weight loss thanks to giving Handayulso-tang(HD) medication of Taeum-in to induced obesity rats and its effects on lipid metabolism, given that their behavior patterns are changed according to their constitution. Methods: The extracts of Handayulso-tang was orally administered to the rats of HD group 200mg/200g of rats weight every day for 6 weeks, and the control group were fed with equal amount of saline. And measured the body weight and total cholesterol, triglyceride, free fatty acid and total lipid contents in serum in obese rats. Results: 1. The body weight in HD group were decreased. 2. The contents of serum total cholesterol and triglyceride in HD group were decreased and statistically showed the significant difference compared with the control group. 3. The contents of serum free fatty acid and total lipid in HD group were decreased, but did not statistically show the significant difference compared with the control group. Conclusion: Based on the above results, we know that Handayulso-tang have effects on the decrease of the body weight and the contents of serum total cholesterol, triglyceride, free fatty acid and total lipid So it could be concluded that Handayulso-tang can help the treatment of obesity.

This study was carried out to investigate the supplementary effects of ${\gamma}$-oryzanol extracted from rice bran on lipid metabolism in diabetic mice. We supplied 2 kinds of experimental diets (CO without and GO with 0.2％ ${\gamma}$-oryzanol) to diabetic mice for 8 weeks. Diet intake, body weight, organ weight, contents of serum and hepatic lipid profiles, and fecal lipid levels were measured. Though there was no significant difference in diet intake, body weight change and organ weight between experimental groups, the concentration of serum total cholesterol and hepatic total lipid, total cholesterol and HMG-CoA reductase activity was significantly lower in GO group treated with 0.2％ ${\gamma}$-oryzanol of diet than CO group after supplementary period of experimental diets. And total lipid, triglyceride, total cholesterol, and bile acid levels excreted to feces were significantly higher in GO group than CO group. These results suggest that ${\gamma}$-oryzanol decrease the serum and hepatic lipid levels by lowing HMG-CoA reductase activity or increasing the contents of fecal lipid in diabetic KK mice.

This experiment was made in order to observe the change in contents of the total cholesterol, free cholesterol and ester cholesterol in the liver and serum by the feeding of glucose and sucrose. The animals used for the experiment were adult male albino rat from a pure strain, weighing 285-332g. The animals were divided into standard, glucose and sucrose diet groups. The glucose and sucrose diet groups were redivided into 10%, 25% and 40% diet groups. Their liver and serum were used as sample after they were fed with the corresponding diets, respectively, for two months. 1. In the liver, the total cholesterol and ester cholesterol contents in the 40% glucose diet group were significantly increased and the free cholesterol contents in all diets were respectively increased, compared with the standard diet group. 2. In the serum, the total cholesterol contents in both diet groups, the 10% glucose and 10% sucrose, were decreased but the content in the 40% sucrose diet group was increased, compared with the standard diet group. The free cholesterol contents in the 10 and 40% glucose diet and 10% sucrose diet group were decreased, compared with the standard diet group. The ester cholesterol contents in the 10% glucose and 10% sucrose diet groups were decreased but the content in the 40% sucrose diet group was increased, compared with the standard diet group. Being taken into consideration of the above facts it was acquired that the cholesterol contents are affected by the amounts and kinds of dietary carbohydrate when the protein contents in each diet were constant.

Mugwort has been used as a Korean folk medicine in treating liver diseases acting as an analgesics, sedative, diuresis, choleretics. This study was perfomed to evaluate the effect of mugwort extracts on the changes of enzyme activities, lipid accumulation of the serum and liver, when hepatotoxicity was induced by benzo(a)pyrene. The results are as follows: 1. Mugwort water extract administration prevented the increase of serum and liver AST, ALT, LDH, ${\gamma}$-GTP, liver ALP activities and bilirubin content caused by B(a)P injection. 2. The increase of serum and liver ALT, LDH, ${\gamma}$-GTP, serum AST activities and liver bilirubin contents in B(a)P treated group were decreased by mugwort methanol extract treatment. 3. Serum and liver total cholesterol, phospholipid, triglyceride level and serum HDL-cholesterol level were increased by B(a)P treatment. After combined treatment of mugwort water and methanul extracts, these lipid content were significantly decreased. 4. The hepatotropic effect of mugwort water extract and after-treatment against B(a)P induced hepatotoxicity was superior to that of methanol extract and pretreatment.

This study was aimed at evaluating the nutritional status of Korean lactating women, who were attending peripheral community clinics in low-income areas, by anthropometric measurement, estimating dietary intakes and analyzing the contents of breast milk components, serum lipid content and fatty acid composition. Regarding anghropometric measurements, maternal circumferences decreased significantly at the trunk but not at the limbs. The skinfold thickness on all regions had the tendency to decrease during lactation. It was found that intakes of energy, protein, lipid and carbohydrates were desirable while calcium, zinc, copper and vitamin A were low and sodium was excessive. The energy $\%$of fat was 22.41$\%$of the total energy which is higher than the RDA for adults but it is proper for lactating women, but energy $\%$ from each fatty acid was usually low and an intake ratio of $\omega$6/$\omega$3 fatty acids was desirable. Accordingly, it is thought that dietary fat intake was balanced in quality. Concentrations of the nutrients in matured human milk showed the same range as that reported form different regions with the exception of calcium and magnesium which were relatively low. Serum lipid contents were decreased with the time postpartum and the average serum lipid content of lactating women were similar to the normal range of adults. Serum polyunsaturated fatty acids. especially $\omega$6 fatty acids have gradually increased with the time postpartum, but the composition were not greatly influenced by dietary intakes.
