Objective & Methods: The purpose of this study is to investigate the effects of Artemisiae Capillaris Herba herbal-acupuncture (ACH-HA) at GB34 (Yangleungchean) on hyperlipidemia induced with alloxan injection and high fat diet in rats. The author performed several experimental items to analyze the levels of various components and enzymes in serum, liver, as well as the histological changes of liver and aorta. Results: 1. ACH-HA solution increased the DPPH radical scavenging activity in rat liver cells. 2. ACH-HA at GB34 significantly decreased the levels of serum total cholesterol, low-density lipoprotein (LDL)-cholesterol, free cholesterol and atherogenic index (AI), while significantly increased the ratios of high-density lipoprotein (HDL)/total cholesterol and phospholipid/total cholesterol in hyperlipidemic rats. 3. ACH-HA at GB34 significantly decreased serum aspartate aminotransferase (AST) level in hyperlipidemic rats. 4. ACH-HA at GB34 significantly increased hepatic glutathione (GSH) activity in hyperlipidemic rats. Conclusion: From the above results, it is suggested that ACH-HA at GB34 may have therapeutic and preventive effects on hyperlipidemia.

The antioxidant activity of resveratrol in cholesterol-fed rats, along with its hypolipidemic effects was determined. Thirty two male Sprague-Dawley (SD) rats were randomly divided into three groups (Control, Res30 and Res70) and fed a hyperlipidemic diet for 4 weeks. Resveratrol was suspended in 0.3% carboxymethyl cellulose (CMC) solution and given to rats of the Res30 and Res70 groups once a day for 4 weeks by oral intubation at a dose of 30 and 70 mg/kg body weight, respectively. The control group received 0.3% CMC solution alone. Resveratrol significantly lowered serum lipid, hepatic cholesterol (TC) and triglyceride (TG) levels compared to the control. Excretion of bile acids was significantly enhanced by resveratrol. The overall potential of the antioxidant system was significantly enhanced by the resveratrol as plasma and hepatic thiobarbituric acid reactive substances (TBARS) levels were lowered while serum superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT) activities were increased in the cholesterol-fed rats. These findings suggest that resveratrol maintains an antioxidant efficacy as well as its anti-hyperlipidemic effect.

Pancreatic lipase-inhibitory activity of the rhizome of Rhei Rhizoma and its antihyperlipidemic activity were measured. Rhei Rhizoma inhibited pancreatic lipase with $IC_{50}$ value of 6.5 mg/ml (triolein as a substrate). Rhei Rhizoma significantly inhibited serum TG level in corn oil feeding-induced mice, and serum TG and cholesterol in Triton WR-1339-induced hyperlipidemic mice. However, Rhei Rhizoma did not show the hypolipidemic activity in high cholesterol diet-induced hyperlipidemic mice. When in vitro pancreatic lipase-inhibitory and in vivo antihyperlipidemic activities of Whangryunhaedoktang (WT) and Chunghyuldan (CD), which is consisted of ingredients of WT and Rhei Rhizoma, were measured, CD exhibited more potent inhibitory activities than WT. Therefore these results suggest that antihyperlipidemic activity of Rhei Rhizoma and CD may be more or less originated from the inhibition of pancreatic lipase.

Objectives : Onion (AlliumcepaL.) is one of the richest sources of flavonoids in human diet. In this study, we studied the effects of onion peel water extract (OPE) on the blood lipid profiles and glucose in rats. Methods : The experimental groups were divided with 5 groups (n = 6) of SD rats: normal diet + distilled water (NC), high-fat diet + Quercetin (PC), high-fat diet + onion peel water extract 4 mg/kg (OPE-4), high-fat diet + onion peel water extract 20 mg/kg (OPE-20), high-fat diet + onion peel water extract 100 mg/kg (OPE-100). Results : The liver fat showed significantly lower weights and size in the OPE-100 group as compared with NC group (p<0.05), The epididymal fat and retroperitoneal fat showed significantly lower weights and sizes in the OPE-4 and OPE-20 group as compared with NC group (p<0.05). The serum levels of total cholesterol, LDL cholesterol and triglyceride were significantly lower in the OPE-4 and OPE-20 group as compared with NC group (p<0.05). The OPE-4 and OPE-20 group showed higher HDL cholesterol concentration than NC group (p<0.05). Atherogenic index of OPE-4 and OPE-20 group was significantly lower in as compared with NC group (p<0.05). The serum levels of glucose significantly lower in the OPE-20 group as compared with NC group (p<0.05). Conclusions : In these results, we suggests that onion peel water extracts supplementation can reduces the serum lipid components and improves the lipid metabolism in hyperlipidemic SD rat induced with a high-fat diet.

Dongchunghacho rice, produced by cultivating Dongchunghacho fungus on rice, could be an effective functional food because it offers added value to rice and thus increases rice consumption. However, the physiological effect of Dongchunghacho rice has not been reported yet although there is increasing consumers demand. Therefore, we investigated the effect of Dongchunghacho rice (unpolished rice cultivated with Cordyceps militaris) on lipid metabolism in hyperlipidemic rats. Forty of 8 wk-old male Sprague-Dawley rats were divided into four groups after a 1 week of adaptation period and fed either a normal diet (66% polished rice diet, NC), high fat (12 g/100 g)-high cholesterol (1 g/100 g) diet with 53% polished rice (HC), or high fat-high cholesterol diets supplemented with 30% of the total rice as either unpolished rice (DR) or Dongchunghacho rice (DR). After 4 weeks, rats fed the Dongchunghacho rice diet with high fat and cholesterol had dramatically lower plasma LDL cholesterol concentrations and atherogenic indexes and higher plasma HDL cholesterol levels compared with the rats consuming polished rice or unpolished rice with high fat and cholesterol diet. Dongchunghacho rice led to less total lipid and total cholesterol accumulation in liver. However, these significant reductions in plasma or hepatic lipid profiles were not closely correlated with fecal total lipid or total cholesterol excretion. The plasma concentration of total cholesterol and triglycerides were not affected by Dongchunghacho rice. This hypolipidemic effect of Dongchunghacho rice seemed to be unrelated to unpolished rice itself, because the plasma and hepatic lipid profiles of DR group were not different from that of the HC group. These results suggest that unpolished rice containing cultivated Cordyceps militaris can improve plasma and hepatic lipid profiles in rats fed with high fat-high cholesterol diet.

Objective : Yegangji-tang (YJT) is noted in China as effective medicine for hyperlipidemia. This experiment was performed to determine the effects of Yegangji-tang (銳降脂湯: YJT) on antioxidant activity and hyperlipidemia induced by hypercholesterolemic diet in mice. Methods : We observed three experimental groups: normal, control, and treatment. Rats were provided a normal diet in the normal group, and the other groups were provided a hypercholesterolemic diet to induce hyperlipidemia. After 2 weeks, YJT was treated to the treatment group. We observed the change of body and liver weight, change of serum total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides, lipid peroxidation and antioxidant activity of liver tissue, cholesterol gene revelation control efficiency, and histologic change of liver and abdominal aorta. Results : Total cholesterol, LDL cholesterol and triglycerides decreased significantly with YJT, whereas HDL cholesterol increased significantly. Lipid peroxidation decreased and antioxidant activity of the liver increased significantly. Gene revelation of ACAT and HMG-CoA reductase in hepatic tissue decreased significantly with YJT. We also found that tissue defects of the liver and abdominal aorta were controlled by YJT on histologic study. Conclusion : These results suggest that YJT might be effective in treatment and prevention of hyperlipidemia.

Active component was sought among three herb medicines, which are used in combination as a traditional medicine prescribed for patients with hyperlipidemia related diseases. Antihyperlipidemic effect of this remedy has previously been shown model by the authors on the animal model. Hyperlipidemia was induced on male Wistar rats by keeping them on high lipid diet for one week, as previously described by the authors. Blood lipid profile was verified on these rats by measuring total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL). Then, the diet was changed to normal. At the same time, methanol extracts of Scutellaris baicalensis Georg.(radix), Coptidis japonica Makino(rhizoma) or Rhei koreanum Nakai(rhizoma) were given on daily basis, and changes in the blood lipid profile were monitored for 4 weeks. Methanol extract of Scutellaris baicalensis Georg. significantly reduced the TC value, implying the in vivo antihyperlipidemic effect.

The effects of cheonggukjang(traditional fermented soybean food, CK) and cheonggukjang added Agaricus blazei (CKA) on lipid metabolism were investigated in female Sprague-Dawley rats (20 weeks old). The rats were fed a purified hyperlipidemic diet (control diet: 0.1% cholesterol, 10% fat, 18% casein) for 4 weeks. The rats were randomly assigned to each treatment group: control, two kinds of CK or CKA (powders of CK or CKA as dietary protein sources). After 8 weeks of experimental diets consumption, the body weights, and the uterine fat pad weights of CK and CKA diets groups were more significantly decreased than those of the control diet group. The liver cholesterol and triglyceride levels were significantly lower in both the CK and CKA diets groups than those in the control group. The concentrations in serum triglyceride, total cholesterol, LDL-cholesterol, and atherogenic index ratios were significantly decreased in the CK and CKA diets group s compared with those in the control group. The HDL-cholesterol/total-cholesterol ratios were significantly increased in the CK and CKA diets groups compared with those in the control group. The fecal cholesterol and triglyceride excretion in the CK and CKA diets groups were more increased than those in the control group. These results showed that both the feeding the rats with cheonggukjang and cheonggukjang added Agaricus blazei decreased the triglyceride, total cholesterol and LDL-cholesterol in serum as well as the triglyceride and cholesterol in liver, and increased the HDL-cholesterol/total-cholesterol ratio in serum.

Onion (Allium cepa L.) is one of the richest sources of flavonoids in human diet. Onion peel contains over 20 times more quercetin than onion flesh. In this study, we studied the effects of onion peel water extract (OPE) on the blood lipid profiles in mice. The onion peel extracts was extracted with hot water. The experimental groups were divided with 3 groups (n = 6) of ICR male mice: normal diet + distilled water (NC), high-fat diet + distilled water (HF), high-fat diet + onion peel water extract 20 mg/kg (OPE-20). The oral administration was conducted daily. The experimental period was 7 weeks. Onion peel water extract showed higher concentration of polyphenol gallic acid and anti-oxidant trolox equivalent than the ethanol extract. The body weight gain and food efficiency ratio was significantly lower in the OPE-20 group as compared with HF group (p < 0.05). The epididymal fat and retroperitoneal fat showed significantly lower weights and sizes in the OPE-20 group as compared with HF group (p < 0.05). The serum levels of total cholesterol, LDL cholesterol and triglyceride were significantly lower in the OPE-20 group as compared with HF group (p < 0.05). The OPE-20 group showed higher HDL cholesterol concentration than HF group (p < 0.05). Atherogenic index was ignificantly lower in as compared with HF group (p < 0.05). The serum levels of glucose, GOT and GPT were significantly lower in the OPE-20 group as compared with HF group (p < 0.05). In these results, we suggests that onion peel water extracts supplementation can reduces the serum lipid components and improves the lipid metabolism in hyperlipidemic mice induced with a high-fat diet.

Objectives: To investigate the effects of Chrysanthemum indicum L. pharmacopuncture on lipids, antioxidant capacity and anti-inflammation in rats fed high-fat diet. Methods: Hyperlipidemic rats induced by high-fat diet were divided into 5 groups: no treatment control (normal, n=8), high-fat diet only control (control, n=8), high-fat diet and Chrysanthemum indicum L. pharmacopuncture at CV4 group (TI, n=8), high-fat diet and Chrysanthemum indicum L. pharmacopuncture at CV17 group (TII, n=8), and high-fat diet and Chrysanthemum indicum L. pharmacopuncture at EX-HN3 group (TIII, n=8). They were given pharmacopuncture accordingly every other day for two weeks followed by analyses of lowering lipids effects, oxidative capacity and anti-inflammatory effects. Results: Compared with the control, pharmacopuncture groups showed significantly decreased plasma total cholesterol (TC), liver thiobarbituric acid reactive substance (TBARS), catalase, glutathione peroxidase, neutrophils, monocytes, plasma and liver IL-$1{\beta}$, and plasma and liver IL-6. In other parameters including plasma and liver triglyceride, liver TC, LDL-cholesterol, HDL-cholesterol, liver TBARS, supraoxide dismutase, total protein, albumin, blood cell analysis, plasma and liver TNF-$\alpha$, and IL-10, there was no significant difference between control and pharmacopuncture groups. No clear acupoint-specificity was observed. Conclusions: Chrysanthemum indicum L. pharmacopuncture may improve control of hyperlipidemia.
