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 carried out to evaluate the effect of Cnidi rhizoma (CR) water extract on fat accumulation in fatted rats induced by the oral high fat administration for six weeks. Total cholesterol, neutral lipid and epididymal fat pad of CR groups were lower than the control group. On the other hand, high density lipoprotein(HDL) -cholesterol was somewhat higher In CR than In the control group. In addition, the same result as the above case was obtained when examining adipose for liver and epididymal fat components. During the feeding experiment, level of low density Lipoprotein(LDL) and very low density Lipoprotein (VLDL) increased while HDL was decreased. The degree of LDL and VLDL was decreased however, and HDL was, increased In CH groups as compared with the control group. Insulin and cortisol were higher than the control group, due to the fat accumulation. Experiment group showed the increased excretion as compared with the control group, in the excretion of bile acid and neutral sterol. The liver of the control group observed by the light microscope appeared to the fatty liver, but CR groups showed some improvement of the fatty liver. Based on the above results, it was shown that It Is possible to improve fat accumulation induced, by high fat dietary through using the oral administration of Cnidi rhizoma boiling extract solutions.

The purpose of this study was to investigate the effects of diet composition on serum leptin and lipids profiles in rats. At the baseline, seven 4-week-old Sprague-Dawley rats, male, were sacrificed and the remaining rats were divided into five groups and each group was fed one of the following five dietary regiments for 2 weeks and 6 weeks;the control diet AIN76(CAL, n=2l), high-carbonhydrate(rice)(HCR, n=2l), high-carbohydrate(flour)(HCF, n=2l), high-fat(corn oil)(HFO, n=2l), high-fat(beef tallow)(HFB, n=2l). Serum leptin was determined by a double antibody ELISA assay at the baseline(n=7), 6 week(n=35) and 10 week of age(n=70). At 6 weeks of age, the increase in the Food Efficiency Ratio(FER) was related to adipocyte hyperplasia in rats on HFB diets. The serum triglyceride, total cholesterol, and LDL-cholesterol increased significantly in HFB group, and decreased in HFO group compared to control group. The HFC group showed significant increase in serum triglyceride level compared with control group. After 2 weeks and 6 weeks, noticeably high increases in epididymal adipose tissue fat cell mass and numbers were observed with the HFB fed group. Serum leptin levels increased as body weight increased over the period of time(4weeks; 1.50$\pm$0.13ng/ml versus 10weeks; 2.08$\pm$-.13ng/ml). And this result shows that there are 193% higher in rats fed high fat-beef tallow diet than the control diet. Serum leptin levels of the HFB group(4.01$\pm$0.39mg/ml) were significantly higher than that of the HFO(2.06$\pm$0.5613ng/ml), CAL(2.08$\pm$0.1313ng/ml), HCR(2.41$\pm$0.2113ng/ml) and HCF(2.80$\pm$0.4713ng/ml) at p<0.05. The serum leptin concentration was positively correlated with the amount of epididymal fat pads(r=0.47 p<0.01), serum triglyceride(r=0.49, p<0.001), tatal cholesterol(r=0.48, p<0.001), LDL-cholesterol(r=0.58, p<0.001), atherogenic index(r=0.67, p<0.001), and inversely correlated with HDL-cholesterol(r=-0.65, p<0.001). In conclusion, the changes in composition of dietary fat and carbohydrate intake could affect changes in concentration of serum lipids and leptin. Especially, the high-fat diet with animal fat source could increase circulating leptin level. (Korean J Nutrition 34(2) : 123-131, 2001)

This study examined the effects of baked garlic powder on the lipid metabolism in rats fed a high-fat/highcholesterol diet for 4 weeks to induce hyperlipidemia. Male Sprague-Dawley rats were assigned to four groups according to the dietary fat, cholesterol and baked garlic powder levels. The experimental groups were normal diet group (N), a high-fat/high-cholesterol diet group (C), a high-fat/high-cholesterol diet with 1.5% baked garlic powder group (GPL) and a high-fat/high-cholesterol diet with 3% baked garlic powder group (GPH). The body weight gain, food intake and food efficiency ratio were similar in the experimental groups. The epididymal adipose tissues weight of the C group was higher than that of the N group, whereas those of the groups fed baked garlic powder were decreased gradually. The ALT and ALP activities were similar in the C groups, but the serum AST and LDH activities elevated by a high-fat/high-cholesterol diet were decreased significantly by feeding a 3% baked garlic powder diet. The serum triglyceride, total cholesterol and LDL-cholesterol levels as well as the atherogenic index and cardiac risk factor tended to decrease in the groups fed baked garlic powder than the C group, whereas the serum HDL-cholesterol level was lower in the C group and remarkably in groups fed baked garlic powder than the control group. The total cholesterol level in the liver and mesenteric adipose tissue and the triglyceride level in epididymal tissue were lower in the groups fed baked garlic powder than the C group. These results suggest that baked garlic powder reduces the serum lipid components and improves the lipid metabolism in hyperlipidemic rats induced with a high-fat/high-cholesterol diet.

This study was performed to examine the effects of onion powder supplementation on lipid metabolism in male SD rats fed a high fat and high cholesterol diet. Experimental groups were control (C), high fat fed group (HF), high fat+onion powder intake (OP), high fat+quercetin intake (Q). The HF diet contained 1% cholesterol, 4% lard, 0.3% Na-taurocholate, and quercetin supplementation level was 0.1 g/kg diet. The OP group showed lower body weight gains compared to the control, while there was no significant difference in food efficiency ratio efficiency. When the proportion of fecal bile acids per total lipids was calculated, there was a significant decrease in the HF group compared to the control group, while the levels of the control group was same as that of the OP group. There was no significant difference between the HF and Q groups in bile acid/total lipid in feces. The amount of total cholesterol in liver increased significantly in HF group compared to the control group, while total cholesterol decreased significantly in the OP group compared to the HF group. There was a significant decrease in GOT (glutamic oxaloacetic transaminase) activity in OP and Q groups compared to the HF group. In conclusion, feeding onion powder to hyperlipidemic rates appeared to control weight gain, significantly lower the level of total cholesterol in the liver, and recover GOT activity. We also demonstrated that onion powder intake was more effective than quercetin intake.

This study was conducted to examine the effects of dietary xylooligosaccharides on lipoprotein lipase (LPL) activitiy in epididymal adipose tissue and lipid composition in serum of rats fed normal or high fat diet. Male Sprague-Dawley male rats weighing 100 $\pm$ 10 g were randomly divided into four groups, two normal diets and two high fat diets containing 1% cholesterol and 10% lard. Two normal diets were classified into a basal diet (normal group) and that with 10% xylooligosaccharide diet (NX group). The high fat diet groups were classified into a HF group without xylooligosaccharides diet and HFX group supplemented with 10% xylooligosacchride diet. Experimental diets were fed ad libitum to the rats for 4 weeks and then they were sacrificed. Body weight, epididymal weight and abdominal weight in HF group were hevier than the those of normal group, but HFX group was significantly reduced compared to HF group. Relative body weight to epididymal weight and relative body weight to abdominal weight in HF group were increased to 50%, 51%, respectively, compared to normal group, but HFX group was reduced 22%, 16%, respectively, compared to HF group. The levels of serum triglyceride, total cholesterol, LDL-cholesterol and atherogenic index in HFX groups were significantly lower than those of HF group, whereas HDL-cholesterol levels were significant increased. Triglyceride contents of epididymal adipose tissue in HF group was increased to 39%, compared to normal group, but HFX group was reduced to 15.8%, compared to HF group. Cholesterol contents of epididymal adipose tissue in HF group was increased 121%, compared to normal group, but HFX group was reduced to 26%, compared to HF group. The activity of LPL in epididymal adipose tissue was increased to 259% in HF group, compared to normal group and HFX group was reduced to 66%, compared to HF group. These result of this study suggested that improved lipid metabolism observed in rats fed xylooligosaccharides may be caused by an alteration of LPL activity in epididymal adipose tissue and lipid composition in serum.

The study was performed by examining the effects of fermented liquid of Crataegi Fructus on the lipid profile improvement in rats fed high fat diets. Sprague-Dawley rats of weighting $180.0{\pm}30g$ were randomly divided into five groups : basal diet (Normal control group, NCG), only high fat diet (High fat control group, HFC), high fat diet and supplemented with 1.69 mg/100 g body weight, 3.38 mg/100 g body weight, 6.76 mg/100 g body weight by fermented liquid of Crataegi Fructus - HFL, HFM, HFH group). These experimental diets were fed for 6 weeks. The fermented liquid of Crataegi Fructus fed groups had more significantly decreased in the levels of serum total cholesterol, triglyceride, LDL-cholesterol and atherogenic index than the high fat control group, while the HDL-cholesterol was higher when compared to the normal control group. Total lipid, total cholesterol, triglyceride, LDL-cholesterol contents in liver were decreased in high fat experimental groups. But the degree of increment was reduced by administration of fermented liquid of Crataegi Fructus. while the fermented liquid of Crataegi Fructus fed group had ore significantly increased in the level of HDL-cholesterol than the high fat control group. The singularity of the unsaturated fatty acid contents attracted our attention. Especially, the polyunsaturated fatty acid compositions were 36.36%, 34.70%, 20.31%in serum, liver and fecal of fermented liquid of Crataegi Fructus fed groups, respectively. These results imply that the fermented liquid of Crataegi Fructus can be used as possible food resources and medicinal food materials.
