The effects of dietary magnesium, calcium on the serum cholesterol concentration in rabbit was studied for a period of 21 days using isocalorids and isonitrogenous basal diet. It is investigated that the serum cholesterol level lowering by feeding with calcium, magnesium, sesame oil and perilla oil, did not appeared but perilla oil and magnesium feeding group appeared a little bit lowering. There was no effect for the total protein, but there was some sort of effect for albumin and globulin. Particulary, alpa-globulin was increased by calcium, magnesium, sesame oil and perilla oil feeding groups. The esterified cholesterol was increased at the magnesium and perilla oil diet group. It is also, investigate that there is almost no effect for the electrolytes concentration and transport phenomena in the cell through magnesium, calcium, sesame oil and perilla oil diet groups.

This study evaluated effects of enzymatic hydrolysates of squid on cholesterol lowering in rats. Thirty male rats were blocked into 3 groups [high cholesterol diet (control), 5% normal squid, and 5% enzymatic hydrolysates of squid] and were raised for 10 weeks. Triglyceride level in enzymatic hydrolysates of squid-fed rats was lower than that in the control. Serum low density lipoprotein-cholesterol level followed in the order of control>normal squid>enzymatic hydrolysates. Serum high density lipoprotein-cholesterol level in enzymatic hydrolysates of squid-fed rats was higher than that in control rats. Liver cholesterol level in enzymatic hydrolysates of squid-fed rats was lower than that in control rats.

In this study, we investigated the effects of lowering the fat and cholesterol in the diets of 26 Korean hypercholesteolemic men($\geq$240mg/dl). They consumed 2378kcal/day with 20.9% of the energy deriving from fat, and a cholesterol intake of 282mg(118mg/1000kcal). The experimental diet consisted of 2400kcal, the same as their usual diet, but the fat content was restricted to 15%, and the cholesterol level to below 100mg/1000kcal. The subjects kept to this diet for four weeks and were asked to maintain their usual life activities during the experimental period. The dietary intake and levels of plasma lipid, lipoprotein-cholesterol and apoprotein of the subjects were analyzed before, two weeks into, and after four weeks dietary intervention. After two of the dietary intervention, there were no significant changes of plasma total cholesterol or triglyceride levels but there was some changes of phospholipid level. However, after four weeks, the levels of plasma total cholesterol, triglyceride, and phospholipid had decreased significantly: 18.2%, 32.9%, and 11.9%, respectively. And the LDL-cholesterol and VLDL-cholesterol levels also showed a marked reduction of 18.1%, and 33.0% respectively without change of HDL-cholesterol level. There were no changes in the levels of Apo-A 1, Apo-B, or Lp(a). The changes of the plasma lipid levels were significantly associated with the changes in dietary fat intake but not the cholesterol intake. In conclusion, although the responses to the dietary intervention varied among the individual subjects, the lowering of dietary fat component from 21% to 15% of energy intake seems to be an effective way to reduce plasma cholesterol and triglyceride levels without decreasing HDL-cholesterol level. It was also found that the restriction of dietary cholesterol to below 100mg/1000kcal not seem to be effective for the hypercholesterolemic patient who already consuming below 300mg/day of cholesterol.

The effect of milk in low and high cholesterol diets were investigated on serum cholesterol esterification. Weanling male Sprague-Dawley rats were divided into low(0.01% w/w) and high (1.01% w/w) cholesterol-diets groups. Bothlow and high cholesterol groups were consisted of three groups : control , LM(low heat milk), and HM (high heat milk) groups. After feeding these experimental diets for six weeks, serum cholesterol (free cholesterol and cholestryl ester) concentration and activity of lecithin.: cholesterol acyltransferase (LCAT) were measured, and serum lipoprotein profile was examined using gel column chromatography. According to the result, activity of LCAT was elevated independently by intakes of high cholesterol and milk , which resulted in the increase of daily turnover of serum cholesteryl ester. However, the turnover of HDL-cholesteryl ester increased only by milk. LCAT activity was moderately correlated with levels of total-and HDL-free choelsterol. It is concluded from the present study that milk had the cholesterol-lowering effect which partly appears to be mediated through facilitated reverse cholesterol transport.

This study was carried out to investigate the effect of phytosterol ester addition on lowering blood cholesterol in cholesterol-reduced Cheddar cheese, which was manufactured by the mixture of cholesterol-reduced cream and skim milk. After the cholesterol reduction process by ${\beta}$-CD treatment, the cholesterol removal rate was in the range of 91.2 to 92.1%. In animal study, 18% of total blood cholesterol was lowered in 8% phytosterol ester-added Cheddar cheese, which was significantly different from that of control. The present study indicated that phytosterol ester addition showed a profound lowering effect of blood with cholesterol-reduced Cheddar cheese.

Objective: This study was conducted to investigate the lipid-lowering effect and safety of Daeshiho-tang in patients with uncontrolled lipid levels by statins. Methods: We investigated patients who had an abnormal lipid profile even when taking statins and who were administered Daeshiho-tang at Kyung-Hee University Korean Medical Hospital for at least one day between January 2008 and December 2018. Their basal characteristics and examinations were reviewed retrospectively with respect to lipid profile, AST, ALT, GGT, BUN, and creatinine. The lipid profile was composed of total cholesterol, triglyceride, LDL-cholesterol, and HDL-cholesterol. Subgroup analysis was performed on each component of dyslipidemia. Results: Among 20 participants, there were 10 males and 10 females. The mean BMI was 23.52. Eighty five percent of the participants were diagnosed as having cerebral infarction. After the administration of Daeshiho-tang, total cholesterol and LDL cholesterol were significantly reduced, to 41.3 mg/dl and 33.95 mg/dl, respectively. In subgroup analyses, total cholesterol and LDL cholesterol were significantly decreased, to 63 mg/dl and 54.6 mg/dl, respectively. Liver and kidney function showed no significant difference after taking Daeshiho-tang. Conclusions: Daeshiho-tang as a decoction or powder had significant lipid-lowering effects on total cholesterol and LDL cholesterol in patients with dyslipidemia. The lipid-lowering effect on total and LDL cholesterol increased in patients with hypercholesterolemia and hyper-LDL-cholesterolemia, respectively. Based on the minimal changes in the liver and kidney function test, Daeshiho-tang would be safe enough to be used in clinics.

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 present study was carried out to investigate the changes in chemical and sensory properties, and cholesterol lowering effect of evening primrose oil (EPO) addition in cholesterol-reduced Cheddar cheese. The cholesterol removal rate reached 92.07% by ${\beta}$-cyclodextrin in the cheese before EPO addition. The thiobarbituric acid (TBA) value of cholesterol-reduced and EPO-added cheese increased with both ripening time and amount of EPO addition. Addition of 5% EPO resulted in a significant difference in TBA value after 4-week ripening, compared with no addition of EPO. The production of short-chain free fatty acids (FFAs) increased with ripening period in all treatments. From 4 week of ripening, the amounts of short-chain FFA in 3 and 5% EPO-added groups were significantly higher than those in other groups. Among sensory characteristics, rancidity was mostly affected by EPO addition, however, the rancidity value of 1% EPO-added was not significantly different from that of EPO-free and cholesterol-reduced cheese. Also, Cheddar cheese flavor was not profoundly affected by 1% EPO addition in all ripening periods. Total blood cholesterol dramatically decreased from 184.0 to 137.1 mg/dL with 5% EPO-added and cholesterol-reduced cheese following 8 weeks of feeding. The present results indicated that 5% EPO addition resulted in a profound lowering effect on blood total cholesterol with some adverse effects on chemical and sensory properties.

This study was conducted to investigate the cholesterol and Triglyceride (TG) lowering and anti-obesity effects of water extract of vegetable formula (onion 25%, carrot 20%, Cabbage 20%, Sweet Pumpkins 20%, Chinese plum 5%, turmeric 5%, morus leaves 5%, SLS) in mice fed high fat-diet. ICR mice were divided into 3 groups; a normal diet group (ND), a high-fat diet group (HFD), a high-fat diet and SLS with 300 mg/kg treated group (HFD+SLS). Body fat gain was increased by high-fat diet and HFD+SLS group showed a definite weight loss. The total cholesterol level in the HFD+SLS group was 328.4 mg/dl which was 27.4% lower than that in the HFD group and the cholesterol-lowering effect of SLS was confirmed. The HFD + SLS group showed 118.1 mg/dl and the triglyceride level in the serum was decreased by 88.7% compared to the HFD group and SLS significantly decreased blood triglyceride levels. RT-PCR showed that the expression of PPAR-${\gamma}$ and the target gene SCD-1 was inhibited in a dose-dependent manner in the SLS-treated group. These results suggest that the SLS water extract may have a cholesterol and triglyceride-lowering effect and inhibit the expression of PPAR-${\gamma}$ and SCD-1 to have an anti-obesity effect.
