  • 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.

  • The cholesterol and fatty acid levels in serum and liver were compared in 4-week-old Sprague-Dawley male fed by addition of polymannuronate (M, 5.0%), polyguluronate (G, 5.0%), and polymannuronate and polyguluronate (MG, 2.5% to each) with by addition of cholesterol (1.0%). Feed efficiency by the addition of M, MG, and G was lower than cholesterol fed group (p<0.01). The liver weights were less in M, MG, and G fed groups than in cholesterol fed group (p<0.01). Triglyceride levels in serum and liver were 58.2∼77.4% and 51.5∼65.5% lower in M, G and MG fed groups than cholesterol fed group, respectively. Total-, LDL-, and free-cholesterol levels in serum and liver in M, MG, and G fed group were significantly lower than cholesterol fed group. The cholesterol levels were the most reduced in M fed group. However, HDL- cholesterol level in serum was increased in M, MG, and G fed group (p<0.01). The of polyene levels were 47% higher in serum and 76% in liver in M fed group than in cholesterol fed group. The activities of GOT and GPT were lower in M, MG, and G fed group than in cholesterol fed group (p<0.01). Above the results demonstrate that supplementation of low molecular polymannuronate in diets improve physiologically lipid composition in serum and liver.

  • Objective The purpose of this case-control study was done to examine the relationship among the acute brain infarction, silent brain infarction and blood lipids. Methods We compared the components of blood lipids among acute brain infarction patients group (n=99), silent brain infarction patients group(n=101) and controls group (n=153). The analysis of the data was done by Frequency Analysis, one-way ANOVA, Post Hoc Test(Duncan), Pearson's Correlation. Results The results were as follows. High density lipoprotein cholesterol(HDL-Chol) was significantly lower in patients of acute brain infarctions group. The blood levels of total cholesterol(T-Chol) was significantly higher in patients of silent brain infarctions. A study on the relationship among the significant variables ; In T-Chol and HDL-Chol, DM(No=0, Yes=1) and Age, they had positive correlation each other. Between Sex(Female=0, Male=1) and HDL-Chol, Age and HDL-Chol, DM and HDL-Chol, they had negative correlation each other. Conclusions These results suggest that low HDL-Chol may be risk factor of acute brain infarction.

  • This study was conducted to investigate the effects of chitosan, chitosan oligomer and beef tallow of different levels on lipid metabolism in rats, Seventy male rats of the Sprague-Dawley strain were blocked into 10 groups according to body weight , and were raised for 4 weeks. Dietary fat levels were 20% en and 40% en, and chitosan and chitosan oligomer were given at levels of 05, 3%, and 5%(wt/wt) of diet. The results are summarized as follows, chitosan oligomer supplement decreased serum total lipid, as chitosan 양, and exhibited a tendency to decrease serum total cholesterol. Chitosan oligomer supplement tended to increase the HDL cholesterol ; total cholesterol ration as chitosan did. Liver total lipid and triglyceride concentration were lower in high fat groups than in low fat groups. Liver total lipid concentrations was decreased slightly by chitosan and sigfnificantly by chitosna ligomer. Epididymal fat pad total lipid. total cholesterol and triglyceride concentration were slightly decreased by chitosan and chitosan oligomer supplement, especially in high fat groups. fat absorptivity was decreased by low fat level, chitisan and chitosan oligamer supplement. Fecal excretion of total lipid and triglyceride were increased by high fat level, chitosan and chi샌무 oligomer supplement. However, fecal excretion of total cholesterol was increased by high fat level and chitosan supplement. This indicated that chitosan and chitosan oligomer were effective in interfering with lipid and triglyceride absorption, In conclusion, chitosan oligomer at levels of 3% and 5% has more effective lipid, cholesterol and triglyceride lowering activity than chitosan.

  • Effects of Bupleuri Radix, Paeonie Radix or Uncariae Ramulus et rncus on experimental yperlipidemia were studied. Hyperlipidemia was induced on male Wistar rats by feeding them on high holesterol diet for one week, as previously described by the authors. Blood lipid profile was verified on these ats by measuring total cholesterol(TC), triglyceride(TG), high density lipoprotein cholesterol(HDL) and low ensity lipoprotein cholesterol(LDL). Then, the rats were followed by feeding normal diet. At the same time, ethanol extracts of the three individual herb medicines were orally administered to the rats for 4 weeks and the parameters above mentioned were monitored. Methanol extract of 5Bupleuri radix reduced the TC value significantly at 2 week point and Paeoneae Radix reduced the TC value at 4 week point in compare to control group, suggesting the antihyperlipidemic effect of the two herbal medicines in vivo. The extract of Uncariae Ramulus et Uncus however did not show antihyperlipidemic effect in our experiment.

  • The lowering effect of cholesterol in Sprague Dawley rats was investigated with panaxydol which was purified from the petroleum ether soluble fraction(PESF) of Korean red ginseng. The level of total cholesterol(TC), Triglyceride(TG) and low density lipoprotein(LOL)-cholesterol in serum was reduced by $48\%,\;47\%\;and\;41\%,$ respectively while high density lipoprotein(HDL)-cholesterol was in creased up to $29\%$ as compared with their control values when the panaxydol(20 umoles. 5 mq/kq/day) was adminstered by intraperitoneal rout for 3 consecutive days along with a $1\%$ cholesterol diet. The hepatic ester cholesterol content which was increased in proportion to the cholesterol content of the diet in the control, clearly decreased with panaxydol administration to about $40\%$ regardless of the two diet cholesterol content. $1\%\;or\;2\%.$ A threshold of supression on the serum lipid levels in both administration routes was observed: the maximium suppression in i.p. and p.o. administration was observed to be at 5mq/kq b.w. and in the range of 50 - 100 mg/kg b.w., respectively. Panaxydol may reduce serum lipid and cholesterol levels by inhibiting cholesterol absorption and/or by modulating the cholesterol metabolism. at least in part.

  • The study examined the effects of dietary green tea powder supplementation on blood glucose, and plasma and liver lipid concentrations in diabetic rats. Twenty-five male Sprague-Dawley rats (body weight $200{\pm}5\;g$) were divided into two groups (diabetic and non-diabetic), which were each randomly divided into two subgroups that were fed a control and 1% green tea powder-supplemented diet. Serum and liver lipid concentrations were measured by established techniques. Low density lipoprotein-cholesterol (LDL-C) was calculated from an established equation. Body weight gain and feed efficiency ratio were lower in diabetic rats than in non-diabetic rats regardless of diet. There were no differences in weight gain in diabetic and non-diabetic rats consuming the control and green tea powder-supplemented diets. The levels of fasting plasma glucose, serum total cholesterol, triglyceride, LDL-C and atherogenic index of diabetic rats were significantly higher than that of non-diabetic rats. Conversely, the levels of high density lipoprotein-cholesterol (HDL-C) of diabetic rats was significantly lower than that of non-diabetic rats. Fasting plasma glucose, serum total cholesterol, triglyceride, LDL-C and atherogenic index were significantly lower in diabetic rats fed the green tea powder diet than in rats fed the control diet, and HDL-C was significantly higher in rats fed the green tea powder diet than in rats fed the control diet. The content of liver total cholesterol and triglyceride of diabetic rats were significantly higher than that of non-diabetic rats. Liver total cholesterol and triglyceride were significantly lower in diabetic rats fed green tea powder-supplemented diet than in rats fed the control diet. It is concluded that green tea powder supplementation positively influences blood glucose and lipid metabolism in diabetic rats. The present study, although not directly applicable to humans, may have some implications for individuals who habitually consume green tea powder.

  • The present study was carried out to investigate the effects of magnesium supplement levels and periods on lipid metabolism in male Sprague-Dawley rats given low protein and magnesium deficient diets. The effect of magnesium supplement levels and periods on lipid metabolism in rats given a low protein and magnesium deficient diet for 2 weeks were investigated. Serum total lipid and triglyceride contents were significantly lower in magnesium supplement group compared with magnesium deficient group. Serum HDL-cholesterol/total cholesterol ratio was significantly increased as magnesium supplement level was increased. Liver total lipid, triglyceride, total cholesterol and phospholipid contents were significantly lower in magnesium supplement group than those in magnesium deficient group. Serum ALP, GOT and GPT activities were significantly decreased in magnesium supplement group compared with magnesium deficient group. In summary, the effect of magnesium supplement on lipid metabolism and enzyme activities were significant and we can see that magnesium supplement level propered to be requirement level(400 mg/kg diet)in the other cases except serum lipid contents.
