This study was designed to find out the effects on the lipid metabolism of two herbs used in folk treatment in Korea The two herbs were A: Equisetum arvense L. (Seddugi), B: Eunymus alatus Siebold (Hwasalnamoo). The experiment was performed with the male rats of Sprague-Dawley which fed on high calorie and animal fat supplemented diets from which 30% of the total calories can from lard. Experimental groups were divided into standard (ST) and two other(A, B) groups for the each herb. Each of the two experimental groups consisted of three subgroups (I, II, III) according to the three different doses of the folk remedy used, which were five times and ten times the dose commonly used in a folk remedy. During the experimental period, total food intake and body weight gains were measured, and FER, CER, PER were calculated at the same times. Serum levels of triglyceride, total lipid, ttal cholesterol, HDL-cholesterol, and total lipid as well as cholesterol contents of the liver were measured at the time of sacrifice. Epididymal fat pads were weighted and an indes was calculated. The results of the effects on the lipid metabolism were as follows : 1.Total food intake and body weight gains increased in group A & B. 2. The serum levels of the total lipid and triglyceride decreased in AIII, BI and BIII.3. The serum level of cholesterol decreased in group B, while level of HDL-Cholesterol were increased in all groups and most effectively in group B. 4. The contents of total liver lipid increased in groups A&B. cholesterol decreased in groups A&B. In conclusion, effects on the lipid metabolism associated with the kinds of herbs a diet were the increase of body weighta and the decrease of total lipid and cholesterol levels in serum and liver.

This study was performed to see effects of whole grape, grape pomace or grape juice intakes on lipid metabolism during aging in old Sprague-Dawely male rats. One hundred twenty rats of 13 months old Sprague-Dawely were blocked into eight groups according to body weight and raised for 3, 5 or 7 months with diets containing 2% (w/w) dried powders of three different pars of grape and 0.02% (w/w) CdCl₂. Body weights of Cd groups were lower than Cd free groups. Kidney and spleen weights were incre ased with age, and EEP weights of Cd groups were lower than those of Cd free groups. Total lipid, triglyceride and total cholesterol concentration in plasma increased with age. Whole grape, grape pomace or grape juice intake lowered plasma total lipid triglyceride and total cholesterol concentrations, and especially grape pomace lowered them markedly. Whole grape, grape pomace or grape juice intake decreased liver total lipid, triglyceride and total cholesterol concentrations and increased fecal lipid excretion. Grape diets decreased and Cd administration increased TBARS concentration in LDL fraction. In conclusion, grape diets were effective in decreasing lipid levels of liver and plasma, TBARS in LDL, and in increasing HDL cholesterol. The grape pomace was most effective among three grape parts. It is plausible that grape might be recommended for the treatment or prevention of cardiovascular disease and delaying aging. (Korean J Nutrition 35 (7): 713∼728, 2002)

To investigate changes in protein and total lipid contents, seed storage protein pattern, and fatty acid composition of germination perilla(Perilla frutescens) seeds. Also, the corresponding value components in cotyledons, hypocotyles and roots were measured according to germination stage. The results were summarized as follows ; During germination, pertein and total lipid contents of Yepsilldalggae and Kwangyang cultivar were decreased continuously. In particular, protein contents rapidly decreased to the 3 days after germination(DAG), and then total lipid contents rapidly decreased between 3 DAG and 10 DAG. In changes of protein and total lipid contents of cotyledons, protein contents of Yeupsildalggae was increased during the germination, but Kwangyang cultivar was decreased during the same periods. The total lipids contents of Yeupsildalggae and Kwangyang cultivar were decreased during the germination. According to SDS-PAGE analysis, there was no detectible polypeptide bands on the gel before seed germination suggesting that this may be due to the rapid degradation of the storage proteins in the mature seed by hydrolyttic enzymes during the stage. During germinatation , the polypeptide band with 27$\sim$28KD of Yeupsildalggae and Kwangyang cultivar were accumulated gradually. In changes of fatty acid composition of total lipid of Yeupsildalggae and Kwangyang cultivar , saturated fatty acids such as palmitic acid and stearic acid increased during the germination. On the other hand, unsaturated fatty acid such as linoleic acid and linolenic acid decreased during the same periods. However, oleic acid increased to the 5 DAG, and then was repidly decreased.

The study was conducted to investigated the effect of dietary levels of zinc (Zn) on lipid metabolism in cadmium (Cd) treated rats. Sixty male Sprague-Dawley rats weighing about 110$\pm$10g were divided into 6 groups. The Zn levels were low (0ppm), control (30 ppm) and Cd-treated groups were administrated with Cd chloride (5.0mg/kg of body weight) by oral intubation at the same time once a week. Serum total lipid, triglyceride , total cholesterol and DHL-cholesterol contents decreased significantly in low Zn group. In serum dietary high Zn group, it decreased significantly in the content of triglyceride but total cholesterol and HDL- cholesterol revealed increase slightly . Total lipid and triglyceride contents increased by Cd oral intubation, but triblyceride content of control group decreased significantly in Cd-treated groups. HDL-cholesterol content also decreased by Cd oral intubationl. Cd-treatment increased total cholesterol content in low Zn group. Liver triglyceride content increased as dietary Zn level became more increasing and total lipid was not influenced by dietary Zn levels. Liver cholesterol content was higher in low and high Zn groups than that of control group. Liver phospholipid content decreased in low Zn group . Oral intubation of Cd increased in the contents of triglyceride and total lipid. The content of liver Zn was not influenced by the dietary low Zn but that of serum showed a remarkable increased . Oral Cd intubation increased the Cd contents of liver and serum.

This study was undertaken to examine the correlations between dietary intakes or anthropometric parameters and the plasma lipid level. measurements of dali nutrients intake, body weight, height, body bass index, skinfold thickness, blood pressure, plasma total lipid, triglyceride and cholesterol were made to each of 124 healthy adult(25-59yrs) : 56 males and 65 females. The mean energy and nutrients intake, anthropometric parameters and plasma lipid levels were all in normal range. In females, the fat and protein intake, the amount and percents to total energy intake, had positive association with the plasma total lipid, but the energy percent from carbohydrate intake was correlated negatively. And body mass index positively correlated with plasma total lipid level, in male and female, Therefore we could postulated the dietary fat intake and body mass index affected to plasma lipid levels in normal conditions of healthy adult.

The present study was carried out to investigate the effects of magnesium supplement levels and periods on lipid metabolism in male Sprague-Dawley rats given low protein and magnesium deficient diets. The effect of magnesium supplement levels and periods on lipid metabolism in rats given a low protein and magnesium deficient diet for 2 weeks were investigated. Serum total lipid and triglyceride contents were significantly lower in magnesium supplement group compared with magnesium deficient group. Serum HDL-cholesterol/total cholesterol ratio was significantly increased as magnesium supplement level was increased. Liver total lipid, triglyceride, total cholesterol and phospholipid contents were significantly lower in magnesium supplement group than those in magnesium deficient group. Serum ALP, GOT and GPT activities were significantly decreased in magnesium supplement group compared with magnesium deficient group. In summary, the effect of magnesium supplement on lipid metabolism and enzyme activities were significant and we can see that magnesium supplement level propered to be requirement level(400 mg/kg diet)in the other cases except serum lipid contents.

In order to observe the effect of tannin on plasma lipid status in human, tannin was supplemented with increasing amounts from 0 to 0.5, 1.0, 2.5g/d early week until 4th week. The results obtained from this research are a follows. Concentration of total lipid in plasma was significantly lower compared to the control group when the level of tannin supplementation was 0.5g/day while the level of tannin 1.0g/day and 2.5g/day did not affect to change the total lipid level. There seems to be no obvious improvement of the plasm lipid status respect to different tannin levels. Despite the result, the excretion of total bile acids in feces was increased and total lipid in plasma was reduced significantly during first time supplementation compared the control.

This study was conducted to investigate the effect of nondigestable substances and calcium such as oligosaccharide, agar, saponin, tannin and calcium on the reduction of lipid status in rats fed high fat diet. In order to make the observation, the lipid content in plasma, liver and the feces, and bile acid excretion were measured of r 4 weeks. the results obtained from this research are as follows. Concentration of total lipid in plasma seemed highest in the control group and were significantly lower in groups oil-gosaccharide, agar and calcium-tannin, compared to the control group. Concentration of total cholesterol in plasma was significantly lower in groups oligosaccharide, agar, calcium and calcium-saponin, compared to the control group. The improvement in lipid status seems to be insignificant with oligosaccharide, showed increase in total bile acids excretion in feces and decrease in total cholesterol in plasma, compared to the control group. These evidence seems to indicate improvement of the plasma lipid status by calcium and agar supplementation.

This study was carried out to investigate the supplementary effects of soybean oil and rice gem oil compared with lard on lipid metabolism of insulin dependent diabetic mice. Streptozotocin-induced diabetic mice were fed three kinds of experimental diets with 20% lipid from lard(L), soy bean oil(SBO) and rice gem oil(RGO) for 7 weeks, respectively. Diet intake, body weight, organs weights and lipids levels of serum, liver and feces were measured. There was no significant difference in diet intake, body and organs weights among experimental groups. But the concentrations of serum triglyceride of SBO and RGO groups, and of serum total cholesterol were lower in RGO group than in the other groups. The hepatic total lipid and total cholesterol levels of RGO group were significantly lower than those of the other groups. The contents of total lipid and total cholesterol excreted in feces of SBO and RGO groups were higher than those of L group, and the significance was shown only in RGO group. These results suggested that soy bean oil and rice germ oil can reduce serum triglyceride and total cholesterol levels and hepatic total lipid concentration of insulin dependent diabetic mice compared with lard as a animal fat source by increasing fecal lipid excretion of these groups. But the significant reducing effects on serum and liver lipid levels were shown only in RGO group, and we need to investigate the hypolipidemic effect of this oil by supplementary level and period.
