Objectives: This study was designed to evaluate lipid-lowering and antioxidant effects of Artemisia capillaris(A. capillaris) using a model of hyperlipidemic rats induced by poloxamer-407. Methods: Rats were previously treated by A. capillaris water extract, and intraperitoneally injected by poloxamer-407 to induce hyperlipidemia. Parameters of serum lipid and oxidative stress biomarkers were determined. Results: 1. A. capillaris ameliorated the elevation of serum total cholesterol, triglyceride, LDL-cholesterol and MDA level. 2. A. capillaris ameliorated the reduction of serum TAC and SOD activities. 3. A. capillaris ameliorated the reduction of serum GSH and GSH-reductase level. Conclusions: According to these results, A. capillaris can be used to treat hyperlipidemia or as basis for making new drugs for treating hyperlipidemia in the future.

The root powder of Angelicae gigantis Radix (RPAGR) is known to he beneficial for liver and blood circulation. In a 6-wk broiler feeding trial, the RPAGR was added at levels of 0, 0.2, 0.5, and 1.0%, respectively. The RPAGR was found to be palatable as birds consumed moreof the test diets than the control(0% RPAGR) diet. The BW gain of 1.0% RPAGR group was higher than the control group. The feed efficiency(F/G) was improved significantly(P<0.01) by feeding 1.0% RPAGR. The RPAGR also caused beneficial effects in various carcass characteristics, i.e., carcass weight, dressing percentage, breast muscle, and thigh meat production. There was no consistent trend in various organ weights by the addition of RPAGR. Also, no consistent trend was found in abdominal fat weight. The serum cholesterol level tended to decrease as the BW increased. No consistent trend was detected in serum triglyceride contents.

This study was conducted to compare the effect of dietary sucrose and starch on the lipid metabolism of Rat fed by low protein diet for 3 and 6 weeks periods. Forty male weanling Spargue-Dawley rats weighing 52.7 grams each, after being adopted for 2 days with standard diet, were blocked into 8 groups and fed experimental diet as designed. Experimental diet were composed of two different levels of proteins, 6% designed as low protein diet and 15% designed as standard protein diet. In each group, the content of serum lipid, serum cholesterol and liver lipid were measured. The results of this experiment were summerized as follows. 1. liver lipid content was tended to be high in the sucrose group of low protein fed animal. 2. the content of total serum lipid was tended to be high in the sucrose group, and this tendency was showed statistical significance in the animals fed by low and standard protein after 6 weeks of experimental period. 3. The difference in the total serum cholesterol content between the sucrose and starch group was not significant

Influence of magnesium and calcium on the serum cholesterol concentration in rabbit blood serum was studied. The subjects were fed with the basal diet and magnesium, calcium and Korea Ginseng. The results obtained are summarized as follows: The subjects body weight fed a basal diet, magnesium, calcium and ginseng powder added did not increased, but the weight of liver was increased. Total cholesterol level of the subject fed ginseng powder 4mg. added diet group showed the lowest concentration. The subjects fed with a basal diet and magnesium/calcium(1:2) added diet showed the lower than anyother group. In case of free cholesterol and cholesterol ester, the subject fed with ginseng powder tap. magnesium/calcium(1:2) added diet showed the lowest concentration. The subjects of the lowest concentration of total cholesterol showed the lowest concentration of low density lipoprotein(LDL) and high density lipoprotein(HDL)/total cholesterol ratio was the higher level than any other group. In case of triglyceride and phospholipid, the subject fed with ginseng powder showed the triglyceride concentration gradually do creased, but phospholipid level was increased positively. In case of electrolytes, sodium and potassium of the subject fed with magnesium, calcium and ginseng powder 4mg added diet showed 120mEq/l 1 and 6.8mEq/l, respectively.

To investigate effects of ethylacetate fraction of onion(EFO) on serum lipid metabolism in rats fed high cholesterol diet, four groups of Sprague-Dawley male rats weighing about 100 g were given a high cholesterol diet of 1% cholesterol and 0.25% sodium cholate and EFO containing three concentrations (1%, 3% and 10%), respectively for 6 weeks. growth rate of the hypercholesterolemic group (control group) was higher than the normal group, whereas the groups given EFO showed a decreasing trends, compared with the control group, especially the most excellent effect in 10% of EFO, but any differences were not found between groups in feed efficiency ratio. Serum concentrations of total cholesterol and LDL-cholesterol were lower, whereas HDL-cholesterol concentration was significantly higher in EFO suplemented-grups than control group in dose dependent manner. EFO increased HDL-cholesterol/total cholesterol ratio and lowered atherogenic index. Free cholesterol and triglyceride concentrations were not decreased significantly with in 6 weeks, but cholesteryl ester concentration was significantly decreased in EFO suplemented groups than control group, and in case of serum phospholipid concentration, EFO was not showed significantly effect, but it gradually increased the level, compared with the control group. Therefore, it might be expected that ethylacetate fraction of onion is believed to be a possible protective or curative effects for the fatty liver and hyperlipidemia-induced by a high cholesterol diet.

We investigated the effects of an ethanol extract of Eriobotrya japonica Lindl. (loquat) leaves (EJ) on the lipid metabolism of serum, liver, and adipose tissue, and antioxidative activity in rats fed a fat/cholesterol diet for four weeks. Male Sprague-Dawley rats weighing 207 g were divided into 4 groups: a normal diet group (N), a high-fat/high-cholesterol diet group (HFC), a high-fat/high-cholesterol diet group administered 200 mg/kg day EJ (HFC-EJL), and a high-fat/high-cholesterol diet group administered 400 mg/kg/day EJ (HFC-EJH). The serum ALT and AST activities of the EJ groups were lower than those of HFC group, but there was no significant change in serum ALP or LDH activities. The serum total and LDL-cholesterol, atherogenic index, and cardiac risk factor tended to be decreased in the EJ groups compared to the HFC group, while the serum HDL-cholesterol decreased in the HFC group and increased only minimally in the EJ groups. The total cholesterol in liver and mesenteric adipose tissues was lower in the EJ groups than in the HFC group. Triglycerides in the mesenteric and epididymal adipose tissues were lower in the EJ groups than in the HFC group. The liver GSH levels of the EJ groups were significantly lower than the HFC group. The liver TBARS content was significantly lower in the EJ groups than in the HFC group. These results suggest that EJ ethanol extract may improve the lipid metabolism of serum, liver, and adipose tissue and prevent oxidative stress by stimulating antioxidative systems in rats fed a high-fat/high-cholesterol diet.

The effects of Paecilomyes japonica on weight gains, food intakes, food efficiency ratios, serum and hepatic lipid concentrations, serum protein levels and serum enzyme activities, were studied in adult male rats. Sprague-Dawley rats,35 weeks old, were given four different types of diets for a succeeding period of five weeks: either a normal diet (5% corn oil), a control diet (high fat; 5% corn oil + 15% lard), a PF diet (control diet + 3% fruiting body of Paecilomyes japonica), or a PM diet (control diet+.3% mycelium of Paecilomyes japonica). The body weight gains, hepatic weights and food efficiency ratios of rats fed the PF or PM diets were significantly lower than those fed the control diet, but were similar to those fed the normal diet. The concentrations of hepatic total lipids, cholesterol and triglyceric, and serum triglyceride, of rats given the PF or PM diets were significantly lower than those given the control diet. Hut the concentrations of total cholesterol, HDL-cholesterol, LDL-cholesterol and phospholipid in the serum of rats fed the control, PF or PM diets were significantly higher than those fed the normal diet. In the serum of rats fed the PF diet, the HDL-cholesterol/total cholesterol ratio was significantly higher and the atherogenic index was significantly lower than those fed the control diet, while such effect was not observed in rats fed the PM diet. The alkaline phosphatase activity in the serum of rats fed the control and PM diets was more significantly decreased compared to rats fed the PF and normal diet. No differences were noted in the weights of the pancreas, kidney and heart, the serum concentrations of glucose, hemoglobin and albumin, and the activities of GOT, GPT and ${\gamma}$-GTP, among the rats on all the experimental diets. In conclusion, the rats fed the PF or PM diets maintained normal body and hepatic weights. Despite of the high intake of fats in the PF and PM diets, the concentrations of hepatic total lipids, cholesterol and triglyceride, and serum triglyceride were decreased.

Effects of fermented milk were tested in Sprague-Dawley male rats. In six treatment 150 rats were fed for 12 months: (1) normal control synthetic pellets+water, (2) cholesterol control synthetic pellets containing 1% of cholesterol and 500, 000 IU of vitamin D2/100 g (cholesterol pellets) +water, (3) cholesterol pellets+25% fermented milk, (4) cholesterol pellets+50% fermented milk, (5) cholesterol pellets+75% fermented milk, (6) cholesterol pellets+100% fermented milk. In 3, 6, 9, 12 months, rats were sacrificed for analysis of samples. Rats received the fermented milk had significantly lower (p<0.05) serum cholesterol levels and higher ratios of HDL-cholesterol to total cholesterol than did the water fed rats. Stomach, heart, abdominal aorta and kidney of rat from fermented milk group showed slighter calcification or necrosis than did those of rat from cholesterol control group. Weight gain, diet intake, and drink consumption were significantly different among groups. Results indicate that fermented milk had a helpful effect of experimental hypercholesteremia and atherosclerosis.
