4주간의 고지혈 유도식이를 섭취시킨 후 고지혈증 유도가 이루어진 실험 동물을 이용하여 생식 섭취로 인한 고지혈증 개선 효과를 확인하고자 하였다. 고지혈 유도가 확인된 실험 동물에게 고지혈사료에 30% 생식을 혼합한 식이를 투여하였을 경우 혈중 콜레스테롤량을 약 37% 정도 감소시킨 것으로 나타났으며, 간조직중의 콜레스테롤 역시 약 28% 감소한 것으로 나타나 생식의 섭취가 체내의 콜레스테롤 농도를 낮추어 주는 효과가 있는 것으로 확인되었다. 또한, 체내 콜레스테롤 구성에 있어서도 관상동맥 질환을 억제하는 것으로 알려진 HDL-C의 함량은 대조군에 대비하여 생식 섭취군이 약 28%정도 증가되었으며, 동맥벽에 축적되어 관상동맥질환 발병과 연관관계가 높은 것으로 알려진 LDL-C의 함량을 약 39%정도 감소시킨 것으로 나타나 체내 콜레스테롤 수치의 저하와 더불어 콜레스테롤의 구성 양상에도 이로운 점을 제공한 것으로 나타났다. 이러한 결과로부터 순환기계 질환 발병율을 나타내는 지표로 널리 이용되는 동맥경화지수와 심혈관위험지수를 산출한 결과 생식 섭취군은 대조군에 대비하여 동맥경화지수의 약 60%를 저하시켰으며, 심혈관위험지수 역시 약 56% 정도 저하시킨 것으로 나타났다. 이상의 결과를 종합하여 볼 때 생식 섭취는 체내 콜레스테롤의 농도를 저하시킴으로서 순환기계 질환의 위험도를 낮추는데 효과가 있는 것으로 생각된다.

Taurine supplementation has been shown to have an effect on lowering blood lipids in ovariectomized (OVX) rats. It therefore seemed desirable to find out whether the beneficial effect of taurine on OVX rats fed calcium-deficient diet could also be reproduced. Forty female Sprague-Dawley rats were divided into two groups. One group was OVX and the other group received a sham operation (Sham). Each rat group was further divided into the control diet and the taurine supplemented (2.0g/100g diet) diet group. All rats were fed on calcium-deficient diet and deionized water ad libitum for 6 weeks. Plasma and liver lipids were determined by using commercial kits. LDL-cholesterol concentrations were estimated with the equation of Friedewald et al. (1972). There were no significant differences in body weight gain and food intake between the control and taurine group within Sham and OVX groups, but body weight gain, food intake, and food efficiency ratio was higher in the OVX group. Concentrations of plasma total cholesterol, triglyceride, LDL-cholesterol were significantly lower in the taurine fed group of OVX rats fed Ca deficient diet, while HDL-cholesterol concentration was increased in the taurine fed group. Therefore, in this study, we examined whether taurine also prevented hypercholesterolemia induced by ovarian hormone deficiency in ovariectomized rats when they were fed a calcium-deficient diet. These results indicate that taurine may have some beneficial effects on hypercholesterolemia and hypertriglyceridemia in OVX rats fed calcium-deficient diet.

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.

The study was conducted to investigate the effect of cholesterol and fiber on serum lipid metabolism in rats. Male Sprague Dawley rats were administrated 1% cholesterol and 0.25% sodium cholate to induce hypercholesterolemia and were fed on diet containing three concentrations(0%, 5%, 10%) of cellulose and pectin, respectively. The rats were sacrified after 5 weeks of feeding periods. Serum triglyceride concentration was significantly decreased in proportion to level of fiber. Phospholipid concentration was more decreased in 10% fiber groups than 5% fiber groups but did not show any difference by fiber types. Free cholesterol and cholesteryl ester concentrations in serum were significantly decreased by fiber supplement and pectin was more effective than cellulose in cholesterol lowering effect. Whereas HDL cholesterol concentration and HDL C/TC were increased in proportion to level of fiber and the effect of pectin was not more significant than that of cellulose. Serum chylomicron cholesterol concentration also showed significant decrease by pectin supplement and LDL , VLDL cholesterol concentrations were more significantly decreased in 10% fiber groups than those of 5% fiber groups. The results indicate that 10% pectin may have beneficial roles in hypercholesterolemia.

Xanthoma is a localized collection of tissue histocytes containing lipid. The majority of tendinous xanthomas probably occurs in the setting of hypercholesterolemia especially in bilateral Achilles tendon xanthomas. Xanthoma of the Achilles tendon is a rather rare, interesting orthopaedic condition that has important ramifications in internal medicine and dermatology because the lesion is associated with a specific disturbance of lipid metabolism. We experienced one case of normolipidemic and symptomatic Achilles tendon xanthoma. Surgical intervention was carried out for cosmetic and symptomatic reasons, the patient undergoing total resection and a reconstruction of the Achilles tendon by the combinedV-Y muscle flap and modified Lindholm technique.

This study was conducted to observe the influences of Crataegus pinnatifida BUNGE extract on lipid concentration in hypercholesterolemic rats (Sprague Dawley, male) fed the experimental diets for 5 weeks. Body weight gain was remarkably lower in the Crataegus pinnatifida BUNGE extract intake group than in the hypercholesterolemic rats. Total cholesterol concentration was remarkably lower in the extract of Crataegus pinnatifida BUNGE supplement in hypercholesterolemic rats than in the hypercholesterolemic model. Whereas, concentrations of HDL-cholesterol, ratio of HDL-cholesterol concentration to total cholesterol were remarkably higher in the extract of Crataegus pinnatifida BUNGE supplement in hypercholesterolemic rats than in the hypercholesterolemic model. Atherosclerotic index (AI), cardiac risk factor (CRF) were remarkably lower in the extract of Crataegus pinnatifida BUNGE supplement in hypercholesterolemic rats than in the hypercholesterolemic model. From the above research, Crataegus pinnatifida BUNGE extract was effective on the lipid concentrations in sera of dietary hypercholesterolemic rats.

The present study was performed to elucidate the hypocholesterolemic action of lecithin on the diet-induced hypercholesterolemia in rats. Male Sprague-Dawley rats (n=24) were fed lecithin-free (control) diet or diets containing $2\%\;or\;5\%$ lecithin for 4 weeks. Hypercholesterolemia was induced by adding $1\%$ cholesterol and $0.5\%$ cholic acid to all diets. No difference was found in food intake and body weight gain among groups. The lecithin treated groups showed significant improvement in the plasma levels of total cholesterol and LDL-cholesterol (p<0.05) compared to the control group, while the plasma triacylglyceride was not significantly affected 1he atherogenic index and HDL-cholesterol level were decreased in the lecithin groups. The diets with $2\%\;or\;5\%$ lecithin significantly decreased the activity of cholestetyl ester transfer protein (CETP) by $14\%\;or\;17\%$, respectively. Also, lecithin diets increased the activity of lecithin: cholesterol acyltransferase (LCAT). These results suggest that lecithin accounts for the hypocholesterolemic effect due to the decreased CETP activity and increased LCAT activity.

Green tea, which has high polyphenols amount, is thought to have hypocholesterolemic effects. The present study was performed to further examine the hypocholesterolemic action of green tea, especially (-) epigallocatechin gallate (EGCG) for its effect on diet-induced hypercholesterolemia in rats. Male Sprague-Dawley rats (n=15) were fed a green tea-free diet (control), $1.0\%$ green tea catechin (catechin) or $0.5\%$ green tea catechin EGCG for seven weeks. Hypercholesterolemia was induced by adding $1\%$ cholesterol and $0.5\%$ cholic acid to all diets. There was no difference in food intake and body weight gain among the groups. The green tea EGCG treatment led to a significant improvement in plasma levels of total cholesterol, low density lipoprotein (LDL)-cholesterol and high density lipoprotein (HDL)/LDL ratio (p<0.05). There was no significant effect on the plasma HDL-cholesterol level. The catechin treatment led to a 4.19-fold increase in the LDL-receptor mRNA level compared to the control, but the EGCG treatment did not affect the hepatic LDL-receptor mRNA level. Our results suggest that when blood cholesterol level is down-regulated by green tea EGCG, the LDL receptor gene-independent pathway may dominate the hypocholesterolemic action of EGCG.
