The effect of Artemisia princeps var orientalis(mugwort) and Circium japonicum var ussuriense (Unggungqui) on lipid metabolism was examined . Thirty rats of 5 experimental groups were fed with a diet containing 1% cholesterol and 0.25% sodium cholate(control diet) and 5% plant powder or its water soluble extract(experimental diet) for 4 weeks. The activity of enzymes related to liver function, lipid components of liver and principle organs, and fecal steroids were assayed. The activity of enzymes was significantly lower in the unggungqui and mugwort powder diet group than in control. Liver total cholesterol , free cholesterol, and triglyceride levels were significantly lower in Unggungqui powder diet groups that in the control. The concentrations of total cholesterol , triglyceride and phospholipid in heart and kidney were comparatively low in the Unggungqui powder diet groups. In each plant powder diet group, the values of serum bile acid were significantly lowe ran the fecal steroid excretion was higher than in the control and the extract diet groups.

This study was conducted to investigate the hypocholesterolemic effects of porphyran and insoluble dietary fiber isolated from laver in rats fed high fat diet containing 1% cholesterol, 0.25% sodium cholate and 12% lard. Rats were fed, ad libitum, diets containing 5% diet fiber as cellulose(normal control or high fat control), porphyran or insoluble dietary fiber for 4 weeks. Among the groups fed high fat diet, liver weight was significantly lower in high fat porphyran group than high fat control. Plasma GOT, GPT, total cholesterol, cholesteryl ester, LDL-cholesterol and liver total cholesterol concentration were significantly lower in high fat porphyran group than high fat control. The feeding of porphyran significantly increased fecal cholesterol and bile acid excretion. The feeding of insoluble dietary fiber had no significant effect on either plasma or liver cholesterol levels, although fecal cholesterol level in the insoluble dietary fiber group was significantly higher than that in the high fat control. The results indicate that porphyran isolated from the laver may exert their hypocholesterolemic effect by increasing excretion of fecal bile acid and cholesterol.

These works were designed to examine the effects of dietary fiber sources and levels on lipid metabolism in rats fed high lard diet. Rats were divided into three($\alpha$-cellulose, polydextrose, carrageenan) groups and were fed with containing 6% fiber diet. Serum, liver and fecal lipid contents were examined after four weeks of dieting. Also, in order to investigate whether hypocholesterolemic effect of dietary fiber at 4 weeks is continued at 8 weeks, rats were fed with diets containing same sources with different levels of each dietary fiber and were sacrificed after eight weeks of dieting. Serum cholesterol in rats fed carrageenan diet and polydextrose diet were reduced compared with $\alpha$-cellulose-fed group at both four and eight weeks dieting. Liver cholesterol in both polydextrose-fed and carrageenan-fed group were lower than $\alpha$-cellulose-fed group. Fecal total group were increased compared with $\alpha$-cellulose-fed group. On the other hand, there was no significant difference between polydextrose-fed and carrageenan-fed group. On the basis of the results, it was suggested that the hypocholesterolemic effect of soluble fiber used in this study (polydextrose, carageenan) on rats was due to the inhibition of cholesterol absorption on the intestinal lumen and acceleration of cholesterol catabolism in the liver and enhancement of bile acids excretion. On the other hand, insoluble fiber($\alpha$-cellulose) showed no hypo-cholesterolemic effect.

This study was performed to investigate the effect of chitosan and NOCC from different sources and of different molecular weights on lipid metabolism. Sprague-Dawley rats were blocked into 26 groups according to body weight, and were raised for 4 weeks. Cadmium chloride was given at the level of 0 or 400 ppm in diet. Various chitosan and NOCC sources were given at the level of 0%(w/w) of diet. Total serum cholesterol and serum triglyceride concentrations were little affected by chitosan and NOCC supplements. However, HDL-cholesterol concentration and HDL : total cholesterol ratio were increased , and liver lipid, cholesterol , and triglyceride concentration were decreased by chitosan and NOCC supplements. The cholesterol and lipid lowering activity depends on fiber sources(crab and shrimp); type (chitosan and NOCC); and molecular weight(low , medium , and high). Among cadmium-free groups, chitosan-fed groups showed greater activity than NOCC -fed groups in lowering cholesterol and lipid levels, and greater fecal excretion of lipids and bile acids. Crab chitosans were more effective in cholesterol and lipid lowering activity than shrimp chitosans. The group fed high molecular weight crab chitosan showed the highest fecal excretion of lipids and bile acids. This indicated that high molecular weight crab chitosan was most effective in interfering with cholesterol and lipid absorption.

This study was carried out to determine the effects of sodium alginate and cellulose on the cholesterol metabolism in cholesterol-fed rats. Thirty male Sprague-Dawley rats were randomly assigned to three dietary treatments. Rats were fed, ad libitum, diets containing 10% dietary fibers as sodium alginate, cellulose or fiber-free with 1% cholesterol for 4 weeks. The results obtained were as follows: the feeding of sodium alginate with 1% cholesterol induced a significant decrease in plasma cholesterol and TG. The feeding of sodium alginate significantly decreased hepatic total lipids and TG levels, whereas the feeding of sodium alginate significantly increased hepatic HMG-CoA reductase activity. The feeding of sodium alginate and cellulose significantly increased fecal cholesterol and bile acid excretion. The excretion of TG in sodium alginate group, however, was two-fold and four-fold increased compared to cellulose and fiber-free group, respectively. As a result of this study, the ingestion of sodium alginate decreased plasma cholesterol and TG concentrations and liver TG concentration. This may be explained by the facts that fecal cholesterol, bile acid and TG level were increased significantly in sodium alginate group. The increased hepatic HMG-CoA reductase activity by sodium alginate feeding appears to be corresponded to whole-body cholesterol homeostasis.

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.

본 연구에서는 in vivo에서 메주단백질이 콜레스테롤 대사에 미치는 효과를 검토하기 위해, 4주령의 Sprague-Dawley rats를 이용하여 0.5% 콜레스테롤을 함유한 식이에 증자대두분말, 메주분말을 단백질원으로 첨가하여 4주간 자유 급식한 후 혈청 및 간장 중의 지질농도와 분변 중 담즙산 함량을 분석하였다. 증자대두, 메주분말을 포함한 식이를 섭취시켰을 때 실험기간 동안 평균 식이 섭취량, 체중 증가량 및 간장의 무게는 실험군 간에 유의적인 차이는 없었다. 혈청 총콜레스테롤 농도는 메주분말 섭취군이 증자대두 섭취군에 비해 유의적으로 낮았으나(p＜0.05), 혈청 HDL-콜레스테롤 농도에 유의한 차이는 군간 관찰되지 않아, 메주분말 투여에 의한 혈청 콜레스테롤 농도의 감소는 VLDL-, LDL-콜레스테롤 농도 저하에 기인함을 보여 주었다. 혈청 중 인지질, 중성지질, 유리지방산 농도는 두 군간에 유의적인 차이를 보이지 않았다. 간장 중 중성지질, 인지질, 콜레스테롤 농도는 두 군간에 유의적인 차이는 없었다. 한편, 분변 중의 담즙산 함량은 메주분말 투여군이 대조군과 증자대두군에 비해 유의적으로 높은 수준을 보였다 (p＜0.05). 이러한 결과로부터 메주분말 투여에 의한 혈청 콜레스테롤 농도의 저하효과는 담즙산 배설량의 증가에 기인된것으로 판단되며, 미생물에 의해 발효된 대두단백질(메주)은 발효되지 않은 대두단백질에 비하여 강한 콜레스테롤 저하작용이 있음을 시사한다.

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.

It has been reported previously that 2,2-methylene bis(3,4,6-trichlorophenoxy acetic acid) (MTPA) is effective treating for clonorchiasis and less toxic to the hosts. In this studies the absorption, distribution and excretion of MTPA were observed. For this purpose $^{14}C-MTPA$ was synthesised from bis(2-hydroxy-3,5,6-trichlorophenoxyl) methan $^{14}C$ and administerd to the normal rabbit in a single dose of 10mg/kg IV or 20 mg/kg P.O. or to the Clonorchis infected rabbit in dose of 20 mg/kg/day for 6 days. Radioactivity in blood, tissue, bile, urine, feces and tissue of the fluke was measured after the drug was given. The concentration of MTPA in these samples were calcurated from the radioactivity. The result obtained as followes. 1. The increase in concentration of MTPA in blood and urine after oral administration of MTPA was so slow that the absorption of MTPA from the gastrointestinal tract appears very slow. 2. It is presumed that the excretion of MTPA also is slow because the reduction of MTPA concentration in blood after IV injection was very slow. 3. Large amount of MTPA was excreted from the bile. 4. During repeat dose of 20mg/kg/day for 6 days the concentration of MTPA in blood and tissue gradually increased. 5. The highest concentration of MTPA in the kidney and liver, heart, lung, spleen and muscle in decreasing order and the lowest concentration in the brain was noted. 6. During daily dose of 20 mg/kg of MTPA for 6 days of administration the concentration of MTPA gradually increased in urine and feces and the concentration of MTPA in feces was higher than of in urine. It appeares that MTPA take place enterophepatic circulation. 7. It is assumed that accumulation in large amount of MTPA in the liver and tissue of clonorchis, excretion of large amount from the bile is a favorable property of MTPA as a chemotherapeutic agent for clonorchiasis.

In experiment 1, rats (n＝6) fed diet containing 10 g/kg cholesterol for 4 wk (control) with either no amaranth (control), amaranth grain (300 g/kg, AG) or amaranth oil (90 g/kg, AO). Both the AG and AO groups had lower concentration of serum and hepatic cholesterol and triglyceride than the controls (p < 0.05). Fecal excretions of cholesterol and bile acid in AO group increased about 4 fold and 2 fold, respectively, while AG affected only bile acid excretion (p < 0.05). In experiment 2, rats (n＝6) were fed the cholesterol diet for 4 wk and injected intraperitoneally with saline (control) or amaranth squalene (AS) for 7d. The hypolipidemic effect of AS was evident in both serum and liver. Fecal excretions of cholesterol and bile acid were greater (p < 0.05) in AS than control. HMG-CoA (3-hydroxy-3-methylglutaryl coenzyme A) reductase activity was reduced in AS group (11.6%, p=0.13). This study suggests that the cholesterol-lowering effect of AS is mediated by greater fecal elimination of steroids through interference with cholesterol absorption.
