Objective : The aim of this study is to investigate the effects of Taeyeumjoweetang (TJT) and Taeyeumjoweebaemahwangtang (TJBM) medication on body weight change and serum total cholesterol, HDL cholesterol, LDL cholesterol, triglyceride, free fatty acid, total lipid, phospholipid level, and CBC of obese rats. Methods : Obese rats induced by high-fat fed are medicated for 7 weeks. 32 rats are divided into four groups depending on the medication; normal group (general-fat fed and no-medication), control group (high-fat fed and no medication), TJT group (high-fat fed and TJT medication) and TJBM group (high-fat fed and TJBM medication). After 7 weeks, obesity related index and CBC are analysed. Results : There is a significant statistical difference between control group and TJBM group for the body weight change, the total cholesterol, HDL cholesterol, and triglyceride level: total cholesterol values of control and TJBM are $59.25{\pm}9.56 mg/d{\ell}$ and $39.13{\pm}9.08 mg/d{\ell}$, respectively; HDL cholesterol values of control and TJBM are $22.0{\pm}1.69 mg/d{\ell}$ and $13.75{\pm}2.19 mg/d{\ell}$, respectively; triglyceride values of control and TJBM are $12.75{\pm}3.37 mg/d{\ell}$ and TJBM : $8.13{\pm}1.64 mg/d{\ell}$, respectively. There is a significant statistical difference between control group, TJT, and TJBM group for free fatty acid and phospholipid level: free fatty acid values of control, TJT, and TJBM are $936.25{\pm}89.59 {\mu}m/{\ell}$, $738.75{\pm}109.47{\mu}m/{\ell}$, and $720{pm}150.71{\mu}m/{\ell}$, respectively; phospholipid values of Control, TJT, and TJBM are $87.13{\pm}11.86mg/d{\ell}$, $70.5{\pm}12.22 mg/d{\ell}$, and $60.5{\pm}11.1 mg/d{\ell}$, respectively. Conclusion : These results suggest that medication of TJT and TJBM is effective for the treatment of obesity. Especially, TJBM is more effective than TJT.

Hypocholesterolemic effects in rats of two hull-less barleys, waxy and nonwaxy-starch genotype, were evaluated by analyzing liver cholesterol and triglycerides. A group fed cellulose control and fiber-free exhibited significant liver lipid accumulation by morphologically observation. In barley fed group, however, lipid disposition in liver was effectively suppressed. The concentrations of cholesterol and triglyceride in liver were significantly reduced in rat fed 5 and 10% fiber diets containing barley flour and ${\beta}-glucan-enriched$ fraction. ${\beta}-Glucan-enriched$ barley fraction as a fiber source showed more cholesterol-lowering than barley flour with cellulose, and this effect of ${\beta}-glucan$ from two hull-less barleys was similar. Liver cholesterol and triglyceride in cellulose control group were 14.5 mg/g and 46.1 mg/g, respectively, while those of barley and ${\beta}-glucan$ fed groups were $5.1{\sim}8.2\;mg/g$ and $20.1{\sim}31.3\;mg/g$, respectively.

The purpose of this study was to investigate the effects of dietary xylooligosaccharide on lipid levels of serum in rats fed high cholesterol diet. Male Sprage-Dawley rats weiging 100$\pm$10g were randomly assigned to groups of two normal(N, N+10X) and four high cholesterol diets which contained 1%(w/w) cholesterol. High cholesterol diet groups were classified to xylooligosaccharide free diet (C group), 5% xylooligosaccharide diet(C+5X group), 10% xylooligosaccharide diet(C+10X group) and 15% xylooligosaccharide diet(C+15X group) according to the level of dietary xylooligosaccharide supplementation. These experimental diets were fed ad libidum for 4 weeks. The weight gain of high cholesterol diet group were significantly increased more than that of normal group, but those of 10% and 15% dietary xylooligosaccharide groups were significantly decreased more than that of high cholesterol diet(C)group. The higher content of xylooligosaccharide, the more food intake was increased. The food efficiencies of 10%, 15% cholesterol diet groups were lower than that of high cholesterol diet(C)group. The levels of serum triglyceride(TG) and total cholestoral were significantly high in cholesterol diet groups compared with normal diet group but were decreased in groups fed 5% and 10% dietary xylooligosaccharide. Especially, the lowest level showed in group fed high cholesterol diet containing 10% xylooligosacchride. High cholesterol diet group containing 10% xylooligosaccharide increased HDL-cholesterol level and then decreased LDL-cholesterol level and atherogenic index compared with other groups. The level of TBARS(thiobarbituric acid reactive substances) in serum was decreased in rat group fed xylooligosaccharide in high cholesterol diet. The higher content of xylooligosacchride, the more gastrointestinal transit time was decreased. The results indicate that dietary xylooligosaccharide can improve status of TG and total cholesterol and repress lipid peroxidation in serum lipid at hypercholesterolemia induced by high cholesterol diet.

The purpose of this research was to investigate the effects of 10%(w/w) of various dietary fiber, pectin(P), lignin(L), cellulose(C) and fiber-free (F) on lipid content of serum, liver and intestinal tissues in rats fed 10% coix oil (C)-or lard(L)-1% cholesterol diets for four weeks. The lard pectin(LP) group was the lowest In body weight gain and feed intake. Liver weight was not affected by dietary fiber and fat sources, and intestinal weight was higher in pectin(CP, LP) groups than in the other groups. Serum cholesterol was significantly lower in pectin(CP, LP) groups than in fiber-free(CF, LF) groups, and was higher in lard fiber-free(LF) than In the other groups(p＜0.05). Serum triglycerides was significantly lower in coix oil pectin(CP) and lignin(CL, LL) than in fiber-free(CF, LF) groups. Liver total lipid and cholesterol content was significantly lower In pectin than In lard fiber-free group, and liver triglycerides was lower in coix oil pectin(CP) than in fiber-free groups (p＜0.05). Lipid content of intestinal tissue was not affected by dietary fiber source. But total lipid and triglyceride content of intestinal tissues was significantly lower, and cholesterol content was higher in coix oil than in lard group(p＜0.05). These results indicate that pectin and lignin reduced serum cholesterol. Pectin also decreased total lipid, cholesterol and triglyceride contents of liver in rats fed either coix oil-or lard-cholesterol diets whereas lignin did not affect liver lipid content.

The hemolytic characteristics of amphotericin B-containing liposomes have been investigated in vitro. From the hemolysis of human erythrocytes against free and liposomal amphotericin B, the marked reduction in the toxicity of amphotericin B was observed by incorporating the drug in egg PC liposomes. For 45 min, free amphotericin B at $9.6\;{\mu}g/ml$ could completely lyse 2 wt% human erythrocytes. However, liposomal amphotericin B had essentially no lytic effect even in the range over $9.6\;{\mu}g/ml$. In the 66 hr-hemolysis experiment, liposomal amphotericin B showed the slowly hemolysing chracteristics during the experimental period regardless of the concentration of amphotericin B but rapid hemolysis only for 12 hr was observed in the case of free amphotericin B and the degree of hemolysis for 12 hr was maintained after that time. Also the hemolysing ability of liposomal amphotericin B at $4\;{\mu}g/ml$ was lower than that of free amphotericin B at the same concentration for 66 hr. On the other hand, the dependence of hemolysis on amphotericin B contents in egg PC liposomes was significant between 1.64 mole% amphotericin B-containing liposomes and 15.79 or 27.27 mole% amphotericin B-containing liposomes. But no marked difference in hemolysis was observed between 15.79 and 27.27 mole% amphotericin B-containing liposomes. Especially, cholesterol as an excipient in amphotericin B-containing liposomes significantly reduced the hemolysis of human erythrocyte. The degree of hemolysis in 5 mole% amphotericin B-containing liposomes was reduced to approximately 50% of value in the cholesterol-free liposomes by adding 50% cholesterol.

Influence of magnesium and calcium on the serum cholesterol concentration in rabbit blood serum was studied. The subjects were fed with the basal diet and magnesium, calcium and Korea Ginseng. The results obtained are summarized as follows: The subjects body weight fed a basal diet, magnesium, calcium and ginseng powder added did not increased, but the weight of liver was increased. Total cholesterol level of the subject fed ginseng powder 4mg. added diet group showed the lowest concentration. The subjects fed with a basal diet and magnesium/calcium(1:2) added diet showed the lower than anyother group. In case of free cholesterol and cholesterol ester, the subject fed with ginseng powder tap. magnesium/calcium(1:2) added diet showed the lowest concentration. The subjects of the lowest concentration of total cholesterol showed the lowest concentration of low density lipoprotein(LDL) and high density lipoprotein(HDL)/total cholesterol ratio was the higher level than any other group. In case of triglyceride and phospholipid, the subject fed with ginseng powder showed the triglyceride concentration gradually do creased, but phospholipid level was increased positively. In case of electrolytes, sodium and potassium of the subject fed with magnesium, calcium and ginseng powder 4mg added diet showed 120mEq/l 1 and 6.8mEq/l, respectively.

There is a marked increase in geriatric disease, especially liver disease, due to the continuous increase in alcohol and fat consumption. Since the fatty liver, induced by alcohol or fat, is basically from abnormalities in the lipid metabolism, it is possible that fatty acid binding protein(FABP) which is related to the fatty acid metabolism may also be abnormal in these livers. FABP is a small molecular weight protein family present in cytosol in high concentration. It has been proposed as a fatty acid transfer protein and as a binding protein responsible for controlling intracellular free fatty acid concentration. In this research, we have examined the relationship between liver FABP and fatty liver induced by alcohol or high cholesterol diet. Rats were fed one of either semipurified liquid diets; control diet containing 65% carbohydrate, 20% protein, and 15% fat or high cholesterol diet containing 1%(w/w) cholesterol or alcohol diet containing 37% of alcohol instead of carbohydrate. After 5 weeks of feeding period, all rats received commercial chow diet for 5 weeks to examine recovery effect. Liver and blood samples were collected at 0, 1, 3, 5 and 10 weeks to analyze lipid compositions. FABP was purified from liver cytosol and injected to rabbit to obtain antiserum. Liver FABP amount was determined by SDS-PAGE and western blotting methods. Fatty acid binding capacity was determined by binding of 14Cpalmitate with the delipidated liver cytosol. Consumption of alcohol increased serum cholesterol, triglyceride concentration and decreased HDL-cholesterol concentration after 5 weeks. Serum apolipoprotein B concentration increased after 3 weeks and LDL-cholesterol and apolipoprotein A concentration changed after 1 week. Liver cholesterol and triglyceride concentration increased after 3 weeks. Consumption of high cholesterol diet changed liver and serum lipid composition after 3 weeks. Swiching to normal diet for 5 weeks did not normalize most of lipid composition in serum and liver except serum and liver except serum cholesterol, triglyceride and liver cholesterol. Liver cytosol FABP content and the fatty acid binding capacity decreased dramatically after 1 week with alcohol consumption. This results indicate that FABP content changes before the changes before the changes of blood or liver lipid composition, suggesting changes of FABP may cause development of the fatty liver induced by alcohol and can be used as an index of detecting a early development of fatty liver.

To investigate effects of ethylacetate fraction of onion(EFO) on serum lipid metabolism in rats fed high cholesterol diet, four groups of Sprague-Dawley male rats weighing about 100 g were given a high cholesterol diet of 1% cholesterol and 0.25% sodium cholate and EFO containing three concentrations (1%, 3% and 10%), respectively for 6 weeks. growth rate of the hypercholesterolemic group (control group) was higher than the normal group, whereas the groups given EFO showed a decreasing trends, compared with the control group, especially the most excellent effect in 10% of EFO, but any differences were not found between groups in feed efficiency ratio. Serum concentrations of total cholesterol and LDL-cholesterol were lower, whereas HDL-cholesterol concentration was significantly higher in EFO suplemented-grups than control group in dose dependent manner. EFO increased HDL-cholesterol/total cholesterol ratio and lowered atherogenic index. Free cholesterol and triglyceride concentrations were not decreased significantly with in 6 weeks, but cholesteryl ester concentration was significantly decreased in EFO suplemented groups than control group, and in case of serum phospholipid concentration, EFO was not showed significantly effect, but it gradually increased the level, compared with the control group. Therefore, it might be expected that ethylacetate fraction of onion is believed to be a possible protective or curative effects for the fatty liver and hyperlipidemia-induced by a high cholesterol diet.

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.

This study was carried out to determine, the effects of sodium alginate and cellulose on the plasma lipoportein composition and cholesterol metabolism inrats.Each experimental diet contained 105 sodium alginate and cellulose by weight, respectivley and rats were fed fro 4 weeks. The results obtained were as follows : The feeding of sodium alginate and cellulose decreased total plasma cholesterol slightly . total cholesterol of Chylomicron /VLDL- , LDL-fraction and liver were decreased significantly insodium alginate group. HDL-cholesterol was slightly increased in soidum alginate group. The feeding of sodium alginate significantly lowered plasma , Chylomicron VLDL-, LDL-fraction and liver TG concentrations compared with those fed fiber-free diet . The HMG-CoA reductase activity was not different among diet groups but the lowest activity was observed in sodium alginate group. The feeding of sodium alginate significantly increased fecal cholesterol , TG, and bile acid excretion . In summary , the ingestion of sodium alginate decreased cholesterol and TG concentrations of plasma and liver. This may be explained by the facts that fecal cholesterol, bile acid and TG level were increased significantly in sodium alginate group.
