We evaluated the effects of newly developed functional food containing Bacillus polyfermenticus SCD as the main material on the lipid and antioxidant metabolisms of hypercholesterolemic rats. Thirty male SD rats were divided into three groups after a 1-week adaptation period and were fed with a high fat-cholesterol diet (control), or with a high fat-cholesterol diet supplemented with low or high doses ($3.1\;{\times}\;10^6\;cfu/day$ or $3.1\;{\times}\;10^8\;cfu/day$) of B. polyfermenticus SCD and other physiological active materials for 6 weeks. Both doses of B. polyfermenticus SCD significantly reduced hepatic total cholesterol and triglycerides, while increasing the fecal excretion rates of total lipid, total cholesterol and triglycerides. B. polyfermenticus SCD increased the total radical trapping antioxidant potential (TRAP). The erythrocytic glutathione peroxidase activity in the B. polyfermenticus groups was significantly lower than that in the control group. Plasma TRAP levels exhibited a highly significant negative correlation with hepatic total cholesterol while a significant positive correlation was detected between fecal total cholesterol and plasma TRAP. This hypolipidemic and antioxidative effect of B. polyfermenticus SCD seemed to be unrelated to its dosage. These results suggest that functional food containing B. polyfermenticus SCD can improve oxidative stress and hepatic lipid profiles by enhancing the excretion of cholesterol and triglycerides in feces of rats fed with high fat-high cholesterol diet.

This study evaluated the in vitro and in vivo hypolipidemic effects of the medicinal mushroom Phellinus pini. The methanol extract (ME) of the fruiting body of Ph. pini was active against pancreatic lipase and cholesterol esterase with 99.14% and 67.23% inhibited activity at 1.0 mg/mL, respectively. It also inhibited 81.81% and 55.33% of ${\alpha}$-glucosidase and ${\alpha}$-amylase activities, respectively, at 2.0 mg/mL. Hyperlipidemia as induced by feeding rats with a high fat and cholesterol diet (HFC). HFC supplemented with a 5% fruiting body powder of Ph. pini (HFC + PhP) significantly reduced plasma total cholesterol, low-density lipoprotein cholesterol, and triglycerides in rats compared with HFC. The reduced levels were comparable to rats fed the normal control diet (NC). The atherogenic index of HFC + PhP rats was significantly lower than that of the HFC rats. The excretion of fecal total lipid and cholesterol in the HFC + PhP rats was significantly higher than those in the NC and HFC rats. Histopathological examinations demonstrated scant deposition of lipids in the liver of rats fed HFC + PhP. The dietary supplementation with the fruiting body powder provided natural plasma lipid and glucose lowering effects in experimental rats without adverse effects on the plasma biochemical parameters and liver function related enzyme activities. Therefore, the hypolipidemic effects of Ph. pini may be due to the inhibitory effects on pancreatic lipase, cholesterol esterase, ${\alpha}$-glucosidase, and ${\alpha}$-amylase, and excretion of excess lipids and cholesterol in the feces.

The ultimate aim of this study is to find high-fiber sources among Korean common foods and to develop a high-fiber supplement which can be useful in the therapeutic diet for the diabetic patients. For this purpose the effect of four kinds of seaweeds(mixture of purple laver & sea lettuce : MPS, sea tanle : ST, sea mustard : SM, agar agar : AA) on the glucose and lipid mtabolism were examined. Seven groups of normal and streptozotocin-induced diabetic rats were fed dietary fiber-free control diet or one of experimental diets containing 7% of one of four seaweeds for six weeks. The effects of seaweeds were campared with the effects of fiber-free diet or pectin diet. ST, SM, and AA showed a tendency of improving glucose tolerance improvement by those seaweeds, however, was less than that by pectin. MPS was found to possess a serum cholesterol-lowering effect which is comparable to that of pectin. All the supplementations of seaweeds induced significant increase in fecal steroids excretion. The amounts of fecal cholesterol excretion follwing in feeding of MPS and SM were as high as the level cause by pectin. The excretion of bile acids in the MPS group was much higher than that in the pectin group. Based on its effects of alleviating the diabetic symptoms in the previous study and of improving the glucose tolerance, sea mustard seems to have a benefical effect on glucose metabolism. The serum cholesterol-lowering effect of MPS possibly due to the significant increase in fecal steroids excretion suggests that MPS may be effective in improving abnormalities of lipid metabolism. Therefore, sea tangle and mixture of purple laver & sea lettuce seem to be promising as an effective source of high-fiber supplement for the diabetic patients.

This study was designed to find out the effects of aerobic exercise on lipid and Ca metabolism in seven healthy college women, aged 20 to 22 years. Metabolic studies were conducted before and after a 10-weeks exercise period, during which subjects participated in the planned aerobic dance program every day except Sunday. The initial mean time engaged in the exercise was 28 minutes and it was gradually increased up to 45 minutes around the middle point of the exercise period. During both of metabolic study periods, the subjects ate experimental diets which supplied about 120g of protein and 600mg of Ca daily and during the rest of the experimental period they ate their usual diets. The use of alcoholic beverages and drugs were prohibited. The results were summarized as follows. 1) The effect of exercise on lipid metabolism. (1) Mean body weight decreased significantly after exercise(p<0.01) and it did not show a significant decline in skinfold thickness and total body fat contents. (2) Serum total cholesterol level decreased significantly after exercise(p<0.05) and TG level also tended to be lower than that of pre-exercise period. Exercise did not exert any influence on the level of serum HDL-cholesterol in this study. (3) Exercise did not alter total lipid content in feces and apparent lipid absorption rate. 2) The effect of exercise on Ca and P metabolism. (1) After exercise, focal Ca excretion was slightly reduced, however, urinary Ca excretion was not significantly changed. In the results, a slight increase was shown in body Ca retention after exercise. (2) Exercise tended to increase urinary P excretion, but neither P balance nor fecal excretion was significantly changed after exercise. (3) Bone mineral content was not affected by exercise. In summary, aerobic exercise decreased total cholesterol and TG level in serum and tended to increase body Ca retention. With the results, it can be concluded that the additional physical activities beyond the normal daily life in college women might prevent some degenerative diseases-suchas atherosclerosis and osteoporosis.

Lipid-lowering effects of the inulin have been demonstrated in animal, yet attempts to reproduce similar effects in humans have generated conflicting results. In this study, the lipid-lowering potential of inulin and especially its effect on bile acid and neutral sterol excretion were investigated in Korean postmenopausal women. Nineteen postmenopausal women were randomly divided into two groups in a double-blind parallel design and consumed one of two supplements for 12 weeks; placebo of 8g maltodextrins/sucrose mixture (placebo group) or 8g inulin (inulin group). There were no significant changes in body weight during the supplementation period in either inulin or placebo group. Dietary consumption of animal fat in both group tended to decrease after 12 weeks of experiment. Intake of cholesterol was lower in placebo group, whereas the decrease of cholesterol intake in inulin group did not reach statistical significance after 12 weeks. The levels of serum total cholesterol (TC) and LDL-cholesterol (LDL-C) were significantly decreased in both placebo (p＜0.05) and inulin group (p＜0.01) after supplementation for 12 weeks compared with the baseline. The levels of serum triglyceride (TG) and HDL-cholesterol (HDL-C) were not significantly affected by inulin supplements, but atherogenic index (AI) and LDL-C/HDL-C ratio (LHR) as a predictor for coronary heart disease were improved (p＜0.01) significantly after inulin supplementation. Therefore, inulin supplement may decrease the risk of cardiovascular disease via improving blood cholesterol level. Fecal weight and pH were not changed after 12 weeks of supplementation. There were no statistically significant changes for the fecal short-chain fatty acids (SCFAs). In inulin group, fecal deoxycholic acid (DCA) was significantly lowered compared with the baseline (p＜0.05) whereas other bile acids were not changed. During the 12 weeks of intervention, no differences were found in fecal excretion of neutral sterol in the two groups. In summary, dietary inulin decreases serum TC, LDL-C, AI, LHR and lowers excretion of fecal DCA in the Korean postmenopausal women. These results support the use of inulin for reducing risk factors for hyperlipidemic postmenopausal women. However, the exact mechanism (s) responsible for the blood lipid lowering action of inulin including altered fecal bile acid remain to be elucidated.

This study was carried out to evaluate the effect of Cnidi rhizoma (CR) water extract on fat accumulation in fatted rats induced by the oral high fat administration for six weeks. Total cholesterol, neutral lipid and epididymal fat pad of CR groups were lower than the control group. On the other hand, high density lipoprotein(HDL) -cholesterol was somewhat higher In CR than In the control group. In addition, the same result as the above case was obtained when examining adipose for liver and epididymal fat components. During the feeding experiment, level of low density Lipoprotein(LDL) and very low density Lipoprotein (VLDL) increased while HDL was decreased. The degree of LDL and VLDL was decreased however, and HDL was, increased In CH groups as compared with the control group. Insulin and cortisol were higher than the control group, due to the fat accumulation. Experiment group showed the increased excretion as compared with the control group, in the excretion of bile acid and neutral sterol. The liver of the control group observed by the light microscope appeared to the fatty liver, but CR groups showed some improvement of the fatty liver. Based on the above results, it was shown that It Is possible to improve fat accumulation induced, by high fat dietary through using the oral administration of Cnidi rhizoma boiling extract solutions.

흰쥐에 cholesterol(0.5%) 및 A. keiskei(5%)를 급여 한 후 혈장 및 간장 지질대사 및 분변 중의 neutral steroids 및 담즙산 배설에 미치는 영향을 관찰하였다. 혈장 cholesterol 농도는 식이중 cholesterol 첨가에 의해 현저히 증가되었으며, A. keiskei 급여시 유의적으로 감소하였다. 식이중 cholesterol 첨가는 혈장 HDL-cholesterol 함량을 유의적으로 감소시키는 반면 LDL-cholesterol을 크게 증가시켜 동맥경화지수를 높였다. A. keiskei 급여는 혈장 LDL-cholesterol의 유의적으로 감소시켰으며, 동맥경화지수도 cholesterol을 급여하지 않은 군에서 0.21, cholesterol 급여 군에서 0.52를 보여 A. keiskei를 급여하지 않은 각각의 대조군에 비하여 유의적 감소를 보여 A. keiskei가 혈장지질 개선효과를 보였다. A. keiskei 급여는 또한 cholesterol 급여와 관계없이 혈장 triglyceride 함량을 유의적으로 감소시키는 결과를 보였으나, 혈장 인지질 함량에는 영향을 미치지 않았다. A. keiskei 급여는 간조직의 total cholesterol, free cholesterol, cholesteryl ester 및 phospholipid 함량에는 영향을 미치지 않았으나, triglyceride 함량은 식이중 cholesterol 첨가와 관계없이 유의적으로 감소시켰다. A. keiskei는 cholestanol, 총 neutral steroid 및 담즙산의 배설을 증가시켰다. 이와 같은 결과로 보아 A. keiskei에 의한 혈장 cholesterol의 감소는 cholesterol 흡수의 감소 및 cholesterol을 cholestanol으로의 전환과 담즙산으로의 배설이 증가됨에 일부 기인하는 것으로 사료된다.

Cholesterol의 주요한 대사산물인 중성steroids와 담즙산의 배설에 관한 내용은 cholesterol 대사를 이해하는데 있어 중요한 부분이다. 식이지방이 steroids의 배설에 미치는 효과에 대하여 아직 일치된 견해가 없어 본 실험에서는 식이지방의 수준(식이에너지의 15, 30 및 45% 과 P/S 비율(0.5 및 1.0)을 달리한 실험식이를 흰쥐에 4주간 급여하여 분변을 통한 총지질, 중성steroids 및 총담즙산배설에 미치는 영향을 조사하였다. 그 결과는 다음과 같다. 체중증가량, 식이섭취량 및 식이변전율은 cholesterol이 섭취되지 않은 경우나 섭취된 경우 모두 P/S 비율에 관계없이 식이지방의 수준에 유의적인 영향을 받았다. 지질소화율은 cholesterol이 섭취되지 않은 경우나 섭취된 경우 모두 P/S 비율에 관계없이 식이지방의 수준에 비례하여 유의적으로 증가하였다. 분변량, 총지질배설량, 중성steroids배설량과 그 조성 및 총담즙산배설량은 식이지방의 수준이나 P/S 비율에 따른 일관성 있는 영향을 나타내지 않았다. Cholesterol의 섭취는 체중증가량과 식이변전율을 유의적으로 향상시켰으며, 총지질배설량을 유의적으로 감소시켰고, 지질소화율을 증가시키고 경향을 나타내었다. 또한 중성 steroids배설량을 증가시키는 경향을 나타내면서, coprostanol의 조성비율을 감소시켰고 coprostanone의 조성비율을 증가시켰다. 반면에 총담즙산배설량은 감소시켰다.
