This study was carried out to investigate the effect of Meristotheca papulosa on lipid concentration of serum and liver in rats fed high fat diet for 4 weeks. Experimental groups ere divided into normal group (5% corn oil), high fat diet group (5% corn oil+20% lard), high fat diet and 5% or 10% Meristotheca papulosa treated group. The weights of kidney, heart and tests were not significantly different among the group, but weight of liver was significantly decreased by supplement of Meristotheca papulosa (10%). The contents of serum total lipid, trigly-ceride, total cholesterol, free cholesterol, cholesterol ester and atherogenic index were decreased, while HDL-cholesterol was increased by Meristotheca papulosa supplementation compared to high fat diet group. Meristotheca papulosa supplement has obvious effects on lowering hepatic total lipid, triglyceride and total cholesterol. Our findings suggest that Meristotheca papulosa supplement can improve lipid metabolism in high fat fed rats.

In this study, ethanolic extracts from Hericium erinaceum cultivated with Artemisia capillaris (HEAC) were assessed for their ability to lower the cholesterol levels of male Sprague-Dawley rats fed a high-fat diet. Rats were randomly subdivided into seven test groups. Each group contained eight rats fed a high-fat diet during a growth period lasting 4 wk. Supplementation with the extracts was performed once a day for 2 wk after the high-fat diet. The control group (rats fed a high-fat diet) showed a high efficiency ratio (feed efficiency ratio) value compared to the normal group. Biochemical parameters, including total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-c), and triglyceride (TG) levels dramatically increased in the control group compared to the normal group. High-density lipoprotein-cholesterol (HDL-c) content in the control group was also significantly lower relative to the normal group. Two positive control groups, treated with simvastatin and atorvastatin, had lowered TC, LDL-c, and TG levels, and increased HDL-c content compared to the control group. Treatment with the tested extracts, including HEAC, ethanolic extracts from Hericium erinaceum, and ethanolic extracts from Artemisia capillaris reduced TC, LDL-c, and TG levels and elevated HDL-c content in the hyperlipidemia rats. The atherogenic index and cardiac risk factor values for the HEAC-treated group were 0.95 and 1.95, respectively. Simvastatin- and atorvastatin-treated groups showed atherogenic index values of 1.56 and 1.69, respectively, and cardiac risk factor values of 2.56 and 2.69, respectively. These results show HEAC possesses an ability to cure hyperlipidemia in rats and may serve as an effective natural medicine for treating hyperlipidemia in humans.

Dietary fatty acids are under intense research to identify anti-atherogenic mechanisms, so we investigated green tea powder (GT) as a protector against atherogenesis originating from lipid peroxidation such as 4-hydroxynonemal (4-HNE) and malondialdehyde (MDA) in different dietary fatty acid-treated apo E KO mice. Growth rate and dietary efficiency were lower in apo E KO mice with or without LA compared to wild type. Plasma total cholesterol (TC) and triacylglycerol (TG) did not correspond to values in other tissues, but TG in heart tissue decreased significantly by GT after linoleic acid (LA) or docosahexaenoic acid (DHA) was administered. LA induced apoptosis as evidenced by changes in aorta morphology and immunohistochemistry. Lipid peroxides (LPO) was increased in apo E KO mice with or without LA corresponding to the accumulation of 4-HNE or MDA in the proximal aorta above the atria. GT consumption tended to reduce the primary causal mechanism of atherogenic phenomena such as oxidizability in both LA and DHA treated atherogenic mice. A high polyunsaturated fatty acids (PUFA) diet involved the changes on stress-induced apoptotic signaling by increasing caspase 3, cytochrome c, and nuclear factor-${\kappa}B$ in the heart tissue, but decreasing the bcl-2 protein. However, GT remarkably reduced the expression of apoptotic signaling, in contrast to the PUFA diet. Therefore, the potential of GT as an anti-atherosclerotic dietary antioxidant was tested in this study.

Curcumin, the yellow pigment in turmeric, curry and mustard, has anti-inflammatory and anti-carcinogenic activities. In this study; we investigated the hypocholesterolemic and anti-atherogenic effect of curcumin in rabbits. Hypercholesterolemia was induced by feeding high cholesterol diet to male rabbits for 30 days, and the animals were then fed high cholesterol diet containing 0.1% (w/w) or 0.5% (w/w) curcumin for additional 30 days. Supplementation of 0.l% curcumin tended to lower serum total cholesterol and low density lipoprotein (LDL)-cholesterol levels and inhibit serum lipid peroxidation. In the 0.5% curcumin-supplemented group, serum total cholesterol was significantly lowered by 11.7%, LDL-cholesterol by 12.8% and lipid peroxidation by 47.9% compared to the control group. Hepatic cholesterol and triglyceride contents were also significantly lowered by 50.6% and 37.4%, respectively compared to the control group. Lipid staining of the arteries isolated from the curcumin-treated rabbits showed that curcumin significantly decreased formation of fatty streaks and atheromatous plaques on the intima of the arteries. These results demonstrated that curcumin lowered serum cholesterol concentration, hepatic cholesterol and triglyceride contents, and accumulation of cholesterol in the artery These cholesterol lowering effects of curcumin, together with its anti-oxidative and anti-inflammatory activities, may play some important roles in preventing atherosclerosis.

Coronary heart disease (CHD) has been the number one killer in western society for a long time, and CHD in most instances is due to atherosclerosis. One of the earliest events in atherogenesis is the intracellular accumulation of lipids, particularly cholesterol esters, in the aortic intima. The lipids presumably came from the uptake of plasma lipoproteins, particularly from LDL. These foam cells were identified as being predominantly as macrophages. Currently, it is believed that oxidation of low density lipoprotein (LDL) might contribute to the generation of foam cells. An outcome of the oxidation hypothesis is that the consumption of antioxidants would be beneficial. In this study, Boldine, an alkaloid of Peumus boldus was tested for their antioxidant potency both in, in vitro oxidation system and in mouse models. Boldine decreased the ex-vivo oxidation of Low-density lipoprotein (LDL). In vivo studies were performed to study the effect of these compounds on the atherosclerotic lesion formation in LDL r-/- mice. Three groups of LDL r-/- mice (N=12 each) were fed an atherogenic diet. Group 1 was given vehicle and group 2 and 3 were given 1 and 5 mg of Boldine/day in addition to the atherogenic diet. The results indicated that there was a decrease in lesion formation reaching a 40% reduction due to Boldine compared to controls. The in vivo tolerance of Boldine in humans (has been used as an herbal medicine in other diseases) should make it an attractive alternative to vitamin E.
