To investigate the effects of hot water soluble extract from Angelicae Gigantis Radix on lipid metabolism and antioxidant defense system in rats fed hypercholesterol diet, Sprague-Dawley male rats were fed either hypercholesterol diet with water or hot water soluble extract from Angelicae Gigantis Radix. Hypercholesterol diet contained 18 % beeftallow and 5 % cholesterol. After 4 weeks of experimental periods serum and liver obtained. The level of serum lipid and the activities of GOT and GPT was measured. The level of lipid and TBARS and the activity of GSH-Px was measured also. The results obtained were: 1) Food intake in the experimental group supplied hot water soluble extract from Angelicae Gigantis Radix was low significantly. 2) In the experimental group supplied hot water soluble extract from Angelicae Gigantis Radix of serum total lipid and total cholesterol was significantly low. 3) Serum GOT activity was significantly low in the experimental group supplied hotwater soluble extract from Angelicae Gigantis Radix. There was no difference of serum GPT activity between control and experimental group supplied hot water soluble extract from angelical Gigantis Radix. 4) There was no difference of lipid composition, TBARS level and GSH-px activity in liver between control and experimental group. The result of this study indicates that the hot water soluble extract from Angelicae Gigantis Radix was effective in decreasing the food intake of the experimental animals in the hypercholesterol diet and also effective in decreasing the levels of serum total lipid, total cholesterol and GOT activity. However it was not effective to change the level of lipid, TBARS and GSH-Px activity of liver.

This research was performed to investigate the effect of Codonopsis lanceolata water extracted on the levels of lipid in serum and liver of rats fed high fat diet for 6 weeks. Experimental groups were divided into normal group(NF), high fat diet group(HF), high fat diet and Codonopsis lanceolata water extract treated group(HFW). Codonopsis lanceolata water extract was orally administrated at the level of 0.1ml/100g body weight per day. Body weight gain and feed intake were not significantly different in three groups, but feed efficiency ratio was increased in HF and HFW. The weights of liver, kidney, heart were not significantly different among the groups. The level of serum total lipid was higher in HF than NF, but Codonopsis lanceolata water extract decreased the level of the lipid. The levels of serum triglyceride and total cholesterol were significantly increased in HF, but they were significantly decreased by administration of Codonopsis lanceolata water extract. The levels of serum HDL-cholesterol and phospholipid were slightly increased by Codonopsis lanceolata water extract. Codonopsis lanceolata water extract significantly decreased the levels of liver total lipid, triglyceride and total cholesterol which were increased by high fat diet.

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.

Secrum lipid and vitamin E levels were determined and smoking, alcohol drinking and exercise habits were asked in 357 healthy male subjects aged 49.4$\pm$6.7 years in Taegu. Average serum levels of total cholesterol, HDL-cholesterol and triglyceride(TG) were 189$\pm$43mg/이, 42$\pm$13mg/dl and 136$\pm$73mg/이, respectively. Serum level of lipid peroxide measured as thiobarbituric acid reactive substances(TBARS) of the subjects was 2.01$\pm$0.73MDA nmoles/ml and that of $\alpha$-tocopherol was 9.53$\pm$3.14ug/ml. The correlation coefficients between $\alpha$-tocopherol and serum lipids were 0.3631 for triglyceride, 0.2993 for cholesterol, and 0.3025 for total lipid. Heavy smokers who smoked more than 20 cigarettes a day had higher levels of TG and TBARS than those who smoke less. Alcohol drinkers had higher levels of TG and TBARS than nondrinkers. Vitamin E level(per ml serum)was significantly higher in the heavy smokers and drinkers, which was reflected by the higher level of serum lipid. When the level of $\alpha$-tocopherol was expressed as $\alpha$-tocopherol/triglyceride, it was negatively correlated with serum TBARS level and was lower in the heavy smokers than in the moderate smokers. It is concluded that vitamin E level as $\alpha$-tocopherol/triglyceride would be better compared to $\alpha$-tocopherol/total cholesterol or $\alpha$-tocopherol/total lipid for the evaluation of vitamin E status in Korean men.

Hyperlipidemia has been treated as one of the most important etiological cause factor in 21th century. The cortex and root of Acanthopanax sessiliflorus (AR), a herbal medicine, have been used for several diseases including cardiovascular diseases in Oriental countries. Recently, we reported that AR has anti-hyperlipidemic action. BS-01 was made using extract from AR. For these reasons, we investigated the effects of BS-01 as anti-hyperlipidemic drug through measurement of body weights, cholesterol levels, total lipid, phospholipid in serum. In our results, mice induced by high fat diet elevated body weight level compared to naive group. And total lipid in serum was also elevated by induction of hyperlipidemia. In BS-01 group, body weight of mice was lowered significantly compared to that of control group. Oral administration of BS-01 decreased total cholesterol and triglyceride level back to that of naive mice. HDL and LDL cholesterol levels were not affected by BS-01. In addition, total lipid level, which elevated by induction of hyperlipidemia was also lowered by oral administration of BS-01. Finally, free fatty acid level was lowered in BS-01 group. These results demonstrate that BS-01 lowered body weight and titers involved in hyperlipdemia such as total cholesterol, triglyceride, free fatty acid and total lipid. In these results, we demonstrate that BS-01 has anti-hyperlipidemic action.

This study was performed to examine the effect of excess vitamin A feeding on lipid profile and vitamin A content of rats. 12 male Sprague-Dawley rats. weighing 114.1$\pm$0.9g, were divided into control and excess vitamin A group, and fed experimental diet for 6 weeks. In the excess vitamin A group, the level of vitamin A was 400, 000 1.U./kg diet(100 times of standard level). It was observed that vitamin A excess group had higher levels of plasma total lipid, total cholesterol, and trighlyceride and lower HDL ratio, indicating a high risk to coronary heart disease. In the liver, total CHOL and TG content were also high, and fatty liver was produced by excess Vitamin A. Vitamin A contents of organs were higher when excess vitamin A was given. These results suggested that excess vitamin A could be a dietary factor increasing the lipid contents of plasma and liver. Therefore, it could be said that vitamin A megadose can be one of the risk factors to coronary heart disease.

This research was designed to study the effect of Korean dietary lipids on the lipid metabolism and the immune function in young rats . The three different lipid sources were compared lard, perilla oil and fish oil. Three different levels of lipid in the diet, 2%, 15% and 30%,on the weight basis, were included. After four weeks feeding, the rats were sacrified and blood sample was collected to analyze for the total lipid, TG and cholesterol contents in serum. The HDL fraction in serum was seperated by the electrophoresis of lipoproteins. The immune responses were measured by the blastogenesis of spleen lymphocyte stimulated by PHA and in serum were measured. The following results were obtained. Lower body weight gain was shown in 30% lipid diet fed group on the isocaloric basis. In concerning the different dietary lipid sources, there were significantly lower boyd weight gain in fish oil than in perilla seed oil and lard group in 30% lipid groups. Deposition of body fat expressed by epididymal fat pad in serum were significantly different among perilla seed oil, lard and fish oil groups. Perilla seed oil group showed lowest level of total lipid and TG in serum regardless of dietary fat level. The feeding perilla seed oil to rats was resulted in lower serum cholesterol levels than lard in all three levels of fats tested. The HDL fraction was elevated in perilla seed oil group at the high fat level. The stimulating responses of lymphycotes by PHA did not seem to be influenced by different dietary fat sources. However, conA mitogenic responses was significantly increased in perilla seed oil group. The lower level of perilla seed oil (2%, 15%) showed slightly higher responses of ConA, indicating that lower level of perilla seed oil might have stimulatory response on the immune response. The number of antibody forming cells of spleen against SRBC was increased in 30% fat level for all the three kind of fats. However, no effect has been found in plaque forming cell response by the differences in dietary fat sources. There were no significant differences in serum IgG and IgA levels in all dietary groups.

The study examines the effects of the Cnidium officinale Makino water extract on hyperlipidemia. For this, three levels (low, moderate, and high) of the Cnidium officinale Makino water extract were supplemented to six-week-old male sprague Dawley rats for five weeks. According to the results, serum total lipid, triglyceride, total cholesterol, and LDL cholesterol levels showed significant decreases (p<0.05) in the group with the Cnidium officinale Makino water extract. The serum total lipid level decreased by 8~22%; the triglyceride level, by 13~25%; the total cholesterol level, by 6~23%; and the LDL cholesterol level, by 14~25%. Total cholesterol and triglyceride levels in the liver were significantly lower in the group with the Cnidium officinale Makino water extract than in the control group (p<0.05), and fecal total cholesterol and triglyceride levels were significantly higher in the group with the Cnidium officinalle Makino water extract. These results suggest that the Cnidium officinale Makino water extract in the hypercholesterol diet may reduce hyperlipidemia, a major cause of cardiovascular disease, by reducing serum cholesterol and triglyceride level in the liver through the facilitation of their excretion by feces.

A simple, reproducible , and accurate enzymatic method using a cholesterol assay kit was developed to quantify total cholesterol content in egg yolk. Total egg yolk lipid was extracted with hexane : isopropanol(3 : 2, v/v) mixture. Samples containing various amount of the total lipid(0-3mg) in optically identifical culture tubes were reacted for 10 min in a water bath (37$^{\circ}C$) with the enzyme solution (5ml) from the cholesterol assay kit. Cholesterol content of the reaction mixturesin culture tubes was spectrophotometrically determined by two different ways : (1) using the culture tube as a curvette(designate culture tube method ; CTM) and (2) the quartz cvette containing the reaction mixture transferred from the culture tube (designate standard cvette method, SCM). CTM revealed lower cholesterol content in 0.1-1.0mg lipid sample range that SCM did, but not significant. For more than 2.0mg lipid sample, CTM gave significantly (p<0.01) lower cholesterol content relative to that by SCM, suggesting that SCM give a false positive result from the sample containing more than 2 mg lipid due to the interference of absorbance by lipid dispersed in the reaction solution . Cholesterol content of less than 1.0mg lipid sample by CTM was proportional to the amount of lipid used, but its linear relationship was not seen in more than 2mg lipid sample. Thus, to determine the appropriate lipid amounts (mg) analyzed . A constant level (41$\mu\textrm{g}$/mg) of cholesterol concentration was observed from the sample containing 0.1-1mg lipid. after which the cholesterol level was dropped to less than 41$\mu\textrm{g}$ /mg. Cholesterol concentration in egg yolk samples quantified by CTM was in accordance with that by GC method. These results suggest that CTM is an useful method for the quantification of cholesterol in egg yolk lipid and other lipids as well.
