Objectives : Dodam-tang has been reported to have a control effect against the hyperlipidemia and thrombosis. Based upon these previous reports, this study investigates the effects of Dodam-tang on the cerebral ischemic damage of the hyperlipidemic rats. Methods : Hyperlipidemia was induced by the beef tallow 30% diet for 14 days on Sprague-Dawley rats. Ischemic damage was induced by the middle cerebral artery occlusion (MCAO) for 2 hours with the intraluminal thread method. Then water extract of Dodam-tang was administered daily for 5 days. The effect of Dodam-tang was evaluated with the serum lipids, infarct volume and edema percentage, and immunohistochemical expressions of iNOS, MMP-9, and GFAP in the brain tissue. Results : The obtained results were as follows; Dodam-tang reduced significantly the infarct size in a TTC-stained 5th brain section of the hyperlipidemic MCAO rats. Dodam-tang suppressed the infarct volume of the hyperlipidemic MCAO rats, but not significant statistically. Dodam-tang suppressed the edema percentage of the hyperlipidemic MCAO rats significantly in the brain tissue. Dodam-tang suppressed significantly the iNOS expression in the cerebral penumbra and caudate putamen of the hyperlipidemic MCAO rats. Dodam-tang suppressed significantly the MMP-9 expression in the cerebral penumbra of the hyperlipidemic MCAO rats. Dodam-tang suppressed significantly the GFAP-expressed atrocytes in the cerebral penumbra of the hyperlipidemic MCAO rats. Conclusions : These results suggest that Dodam-tang suppresses the brain edema formation through the suppression of the iNOS, MMP-9 and GFAP, but the neuroprotective effect against the cerebral infarct are not distinct.

Objectives : SimJeok-Hwan (CP, Cardiotonic Pills) is the traditional remedy to treat patients with coronary arteriosclerosis, angina pectoris and hyperlipidemia. This study was designed to investigate the effects of CP on changes in serum cholesterol levels in hyperlipidemic rats. Methods : In this study, we investigated the effects of CP on changes in body weights, food and water uptake, fasting blood glucose, total cholesterols, HDL-cholesterol, and triglyceride in hyperlipidemic rats. Results : In our results, body weights of hyperlipidemic rats induced by high fat diet did not changed, and treatment with CP did not affect body weights in hyperlipidemic rats. For experimental period, food and water uptake in CP administered group were the same as those in hyperlipidemic control group. In this experiment, treatment with CP decreased total cholesterol and triglyceride in serum which elevated by high fat diet respectively. Conclusions : These results suggest that CP is useful to treat patients with disease related to hyperlipidemia because CP can decrease cholesterol in serum

This study was performed to observe the effects of the feeding physiological activity substance in Cordyceps militaris hot-water extract intake on the improvement of lipid components and metabolic enzyme activities in the serum of dietary hyperlipidemic rats (SD strain, male) fed the experimental diets for 5 weeks. The concentrations of cholesterol (total cholesterol, ${\beta}$-lipoprotein, LDL-cholesterol, free cholesterol and cholesteryl ester), atherosclerotic index, triglyceride (TG), phospholipid (PL) and blood glucose in sera were remarkably lower in the Cordyceps militaris extract intake group than in the hyperlipidemic rats. In the ratio of HDL-cholesterol concentration was higher percentage in the Cordyceps militaris extract intake group than in the hyperlipidemic rats. The activities aminotransferase (AST, ALT) in sera were rather lower in the Cordyceps militaris extract administration than in the hyperlipidemic rats. From the above research, Cordyceps militaris extract were effective on the improvement of the lipid compositions in sera of dietary hyperlipidemic rats.

Hyperlipidemia is caused by high dietary intake of cholesterol and saturated fats, and is known as a major risk factor for atherosclerosis. In the oriental medicine, Cheunggansoyo-san (CGSYS) has been used for supplementing hematopoietic function and for treating cardiovascular disorders. In the present study, CGSYS was administered into hyperlipidemic mice. Increases in body weight and cholesterol levels induced by hyperlipidemic diets for 6 weeks were significantly inhibited by CGSYS administration. Serum levels of glucose, triglyceride, SGOT, and SGPT values were all decreased by CGSYS treatment compared with hyperlipidemic dietary mice. Moreover, CGSYS decreased LDL-cholesterol, but increased HDL-cholesterol levels in hyperlipidemic mice. Thus, the present results suggest that CGSYS appears to De effective for down-regulating risk factors of hyperlipidemia.

Antihyperlipidemic effect of taurine was investigated in the hyperlipidemic rats induced by feeding a diet supplemented with cholesterol (1.5% in diet), vitamin $D_2$(1.25 million IU/kg of diet) and cholic acid (0.5% in diet). The rats were fed the diet containing 1% and 3% of taurine for 8 weeks. The contents of the cholesterol and triglycerides in the serum and liver of the hyperlipidemic rats were increased as compared with those of the control group. Feeding taurine resulted in decreases in total cholesterol and triglyceride levels. The HDL-cholesterol level in serum was decreased in the hyperlipidemic rats, but by administration of taurine its level was increased. In the aorta of the animals, total cholesterol and triglycerides contents were reduced significantly by treatment with taurine. The contents of calcium in the heart of hyperlipidemic rats were greatly increased as compared with those of the control group. Treatment of taurine produced significant decreases in calcium contents in the heart muscle of the animals. These results showed that the hyperlipidemic states in this model of rats were reversed by treatment of taurine.

This study aimed to investigate the improvement effect of 5% (w/w) mung bean (Phaseolus aureus L.) on lipid composition and protein concentration in hyperlipidemic rats. Seven-week-old male (Sprague-Dawley) rats were divided into four groups (n=6, each), and fed experimental diets containing mung bean meal [basal diet+5% (w/w) mung bean (BM), basal-hyperlipidemic diet+5% (w/w) mung bean (BHM)], basal-hyperlipidemic diet (BH), and control (basal diet, BD). Lipid composition in the mung bean diet groups (BM and BHM) evidenced significant reductions in serum total cholesterol, low-density lipoprotein cholesterol, atherosclerotic index, cardiac risk factor, triglyceride, phospholipid, free cholesterol, cholesteryl ester, blood glucose, nonesterified fatty acid, and an elevation in high-density lipoprotein cholesterol. The serum albumin/globulin ratio was increased in mung bean diet-supplemented rats compared to that in hyperlipidemic rats (p < 0.05). Total calcium, phosphorus and potassium concentrations in sera were higher in the BM, BHM and BD groups than in the BH group. Concentrations of sodium and chlorine in sera were lower in the mung bean diet-supplemented groups than in the hyperlipidemic group. The in vivo experiments showed that ingestion of mung bean was effective in improving lipid composition, protein concentration, and blood glucose.

We attempted to determine the action target of Shiitake mushroom extract with a known anti-hyperlipidemic effect in poloxamer(P) 407-induced hyperlipidemia model. We investigated the anti-hyperlipidemic effects of the water extract from Shiitake mushroom on the progress of high fat diet for 4 weeks. Experimental rats were divided into 5 different experimental groups including an normal group (normal diet; n=10), control group (hyperlipidemia; n=10), Experimental group I (hyperlipidemic rats treated with Shiitake mushroom extract (100 mg/kg, PO), n=10), Experimental group II (hyperlipidemic rats treated with Shiitake mushroom extract (300 mg/kg, PO), n=10), and Experimental group III (hyperlipidemic rats treated with Shiitake mushroom extract (500 mg/kg, PO), n=10). It is to analysis changes in body weight, visceral fat weight, blood lipid profiles, HMG-CoA reductase and histological findings. Body weight and epididymal fat weight was not significantly change in experimental groups (p>0.05). The level of total cholesterol, TG, arthrogenic index, and HMG-CoA reductase were significantly lower in experimental groups than control group (p<0.05). These results suggested that the Shiitake mushroom extract administration may act by inhibitory the release of cholesterol related factors and HMG-CoA from the hepatocyte without liver and kidney cell damage in hyperlipidemia rats.

This study was designed to investigate the effects KH-204 on erectile dysfunction in hyperlipidemic rat. KH-204 has been evaluated antihyperlipidemic and antierectile dysfunction effects on experimental hyperlipidemic rats induced by high fat diet. After oral administration of the water extract KH-204 (50, 100, 200, 300 mg/kg) to hyperlipidemic rats for 8 weeks, the variables including body weight, total cholesterol, HDL and LDL levels in serum, the expression of eNOS and nNOS in penis were measured. And erectile function was determined by measurement of intracavernosal pressure (ICP) and maximal arterial pressure (MAP) after electrical stimulation of the cavernosal nerve. Oral administration of KH-204 significantly inhibited the increases of serum total cholesterol and LDL-cholesterol levels and the decreased of serum HDL-cholesterol levels in hyperlipidemic rats induced by high fat diet. The penile expression level of the two enzyme (eNOS, nNOS) were increased significantly after oral administration of the KH-204 50 mg/kg. Erectile function after 10 volts stimulation was significantly decreased in the hyperlipidemic rat compared with the normal rat, but increased in KH-204 group compared with hyperlipidemic group. These results suggest that KH-204 is effective for erectile dysfunction in hyperlipidemia.
