  • In this study, the ameliorating effect of soybean embryos on the impact of alcohol consumption was investigated on rat hepatocytes and in reducing total serum cholesterol levels and total serum lipid levels. Liver histology and two clinically important enzyme markers, aspartate aminotransferase (AST) and alanine aminotransferase (ALT), of rats administered with both alcohol and soybean embryo were compared with a control group. The treatment regimen of soybean embryo significantly reduced the serum ALT and AST levels of the subjects, demonstrating the hepato-protective effects of soybean embryo. Electron microscopy indicated that the administration of soybean embryo preserved the important hepatocyte structures and prevented the presence of lipid droplets and secondary lysosomes. Furthermore, total cholesterol and total lipid levels were significantly reduced. These results indicate that treatment with soybean embryo can positively mediate the effects of alcohol on hepatocytes and general liver functions.

  • This study was performed to investigate effect of dietary fibers in rice and barley on glucose, lipid and cadmium (Cd) metabolism in the rat. Fifty-six male Spague-Dawley rats weighing 244.6$\pm$2.7g were blocked into eight groups according to body weight and raised for four weeks with diets containing 0 or 0.04%(w/w) CdCl2 and four different carbohydrate sources, starch, rice flour, barley flour and mixture of rice and barley flour(7 : 3, w/w). Total dietary fibers and $\beta$-glucan contents of barley were about three times higher than those of rice (10.75% vs. 3.94%, 3.11% vs. 1.06%, respectively). Food intake, weight gain, food efficiency ratio, liver and kidney weights were lower in Cd exposed groups, and barley group among Cd exposed animals showed highest weight gain, food efficiency ratio and organ weights. Fasting serum glucose levels were not significantly different among groups, Serum cholesterol level was lowest in Cd exposed barley group. Serum HDL-cholesterol level was higher in none-Cd exposed starch and barley groups, and HDL-cholesterol : total cholesterol ratios were higher in none-Cd rice and mixed flour groups than other groups. Liver total lipid and triglyceride levels were lowest in barley groups regardless of Cd administration. Fecal total lipid, cholesterol and triglyceride excretions were high in barley and mixed flour groups. Liver Cd concentrations were low in Cd exposed barley and mixed flour groups. In Cd exposed barley group, fecal weight and Cd excretion were highest and Cd retention ratio was lowest among groups. Small intestine metallothionein(MT) concentration was highest in Cd exposed rice group, and kidney MT concentration was highest in Cd exposed barley group. In conclusion, cereals showed different effects on lipid and Cd metabolism that might be mediated by dietary fibers in cereals. Especially $\beta$-glucan-rich barley group showed greatest lipid and Cd lowering effects by increasing fecal lipids and Cd excretions.

  • This study was performed to evaluate the effect of red-yeast-rice on blood lipids and also to investigated the relation of blood lipids, bone related hormones, and bone mineral density in overiectomized rats. Forty female rats (body weight $210\pm5$g) were divided into two groups. The rats in the first group were ovariectomized which the others received sham operation (SHAM). And then each rat group was further divided into control diet $(casein\;20\%)$ and red-yeast-rice powder supplemented $(0.1\%)$ diet group. All rats were fed on experimental diet and deionized water ad libitum for 9 weeks. Bone mineral density (BMD) and bone mineral content (BMC) were measured using PIXImus in spine and femur. Bone formation and bone resorption were measured by serum osteocalcin and urinary deoxypyridinoline (DPD) crosslinks value. Serum growth hormone, IGF-1 and calcitonin were analyzed using radioimmunoassay kits. The red-yeast-rice group had significantly lower the blood triglyceride concentration and had lower the blood total cholesterol concentration than casein group did in ovariectomized rats. And the red-yeast-rice group than casein group in ovariectomized rats. The red-yeast-rice group had significantly lower the atherogenic index than control group within the ovariectomized groups. In the experimental rats, serum total cholesterol concentration was negatively correlated with femur BMC and crosslink value. Crosslink value was negatively correlated with spine BMC and IGF-1. Osteocalcin concentration was negatively correlated with crosslink value. Growth hormone was negatively correlated with crosslink value and positively correlated with spine BMC. The findings of this study suggest that red-yeast-rices are beneficial for blood lipid in ovariectomized rats. And when considering a population-based public health approach to lowering cholesterol and bone loss, and preventing coronary heart disease and osteoporosis, the red-yeast-rice dietary supplement could provide a new approach for the maintenance of healthier cholesterol and bone.

  • Objective & Methods: The purpose of this study is to investigate the effects of Artemisiae Capillaris Herba herbal-acupuncture (ACH-HA) at GB34 (Yangleungchean) on hyperlipidemia induced with alloxan injection and high fat diet in rats. The author performed several experimental items to analyze the levels of various components and enzymes in serum, liver, as well as the histological changes of liver and aorta. Results: 1. ACH-HA solution increased the DPPH radical scavenging activity in rat liver cells. 2. ACH-HA at GB34 significantly decreased the levels of serum total cholesterol, low-density lipoprotein (LDL)-cholesterol, free cholesterol and atherogenic index (AI), while significantly increased the ratios of high-density lipoprotein (HDL)/total cholesterol and phospholipid/total cholesterol in hyperlipidemic rats. 3. ACH-HA at GB34 significantly decreased serum aspartate aminotransferase (AST) level in hyperlipidemic rats. 4. ACH-HA at GB34 significantly increased hepatic glutathione (GSH) activity in hyperlipidemic rats. Conclusion: From the above results, it is suggested that ACH-HA at GB34 may have therapeutic and preventive effects on hyperlipidemia.

  • The aim of this study was to evaluate the effect of Lycii fructus (LF) on serum lipid and the collagen content of the connective tissues in ovariectomized rats. From day 2 until day 37 after the ovariectomy, Sprague-Dawley female rats were randomly assigned to the following groups : sham-operated rat (Sham), ovariectomized control rat (OVX-control), and ovariectomized rats supplemented with the LF 50mg/kg bw/day (OVX-LF). The LF ethanol extract were orally administrated 1ml per day. Body weight gain was not significantly different in groups. Although total-cholesterol and triglyceride were increased in the ovariectomized control, supplementation with the LF extract decreased the levels. Moreover, the serum HDL-cholesterol levels were significantly increased after supplementation with the LF extract(p<0.05). Supplementation with the LF extract prevented a decrease in the collagen level in bone and cartilage tissues. These results are consistent with the conclusions based on the estrogenic activities of LF. Therefore, it may be used to possibly improve the quality of life in menopausal women.

  • 본 연구는 대두단백가수분해물의 섭취가 소화흡수율, 지질대사 및 항산화에 미치는 영향을 살펴보고자 흰쥐를 카제인, 분리대두단백 (ISP) 또는 대두단백가수분해물 (서리태단백분해물 (SH), 수용성단백분해물 (SS) 또는 불용성단백분해물 (IS)군으로 나누어 4주간 사육한 후 생리활성의 변화를 살펴보았으며, 그 결과를 요약하면 다음과 같다. 1) 지질소화흡수율은 실험 1주차에서 분리대두단백군 (ISP군)이 다른 군보다 유의적으로 낮았다. 불용성가수분해물군 (IS군)은 실험 4주차에서 다른 군들보다 콜레스테롤의 소화흡수율이 낮은 경향이었다. 2) 혈액 중성지방은 불용성가수분해물군 (IS군)이 카제인군보다 유의적으로 낮았고, 서리태가수분해물과 ISP군도 낮은 경향이었다. 총 콜레스테롤도 중성지방과 마찬가지로 불용성가수분해물군이 가장 낮았고 다른 대두가수분해물군들과ISP군도 카제인군보다 낮은 경향이었다. 대두가수분해물군들이 카제인군보다 HDL-cholesterol은 높이고, LDL-cholsterol은 낮추어서 동맥경화지수는 불용성, 수용성, 서리태가수분해물의 순으로 낮았다. 3) 총항산화력은 군 간에 유의적인 차이가 없었으나 서리태가수분해물군 (SH군)이 다른 군들에 비해 높은 경향이었다. 간의 항산화효소활성은 각 군 간에 유의적인 차이는 없었으나 서리태가수분해물군의 superoxide dismutase, glutathione peroxidase 및 catalase 활성이 카제인군과 다른 실험군들에 비해 높은 경향이었다. 결론적으로, 대두단백가수분해물군들은 카제인군보다 혈액 중성지질, 총콜레스테롤, LDL-cholesterol과 동백경화 지표 (AI)를 낮추어서 심혈관질환예방에 바람직한 것으로 나타났는데, 이러한 효과는 특히 불용성단백가수분해물군에서 뛰어났다. 한편, 항산화활성의 경우 총항산화력과 항산화효소활성이 서리태가수분해물군에서 높은 경향으로 나타나 앞으로 서리태의 항산화 효과의 원인물질을 규명하고 분리추출하는 등의 연구를 통해 우리나라의 전통 콩의 우수한 면모를 밝히는 연구가 더 필요하다고 사료된다.

  • 본 실험은 적하수오를 식이에 0.5%, 1% 혼합하여 5주간 섭취시켰을 때 적하수오가 고 콜레스테롤 식이를 장기 급여한 SD rat의 지질대사에 미치는 영향을 확인함으로써 적하수오의 기능성식품 소재로서의 가능성을 확인하였다. 실험기간 중 실험쥐의 체중증가는 1% cholesterol을 첨가한 그룹에서 cholesterol 대조군(II)에 비해서 적하수오를 섭취시킨 V군(1% cholesterol, 0.5% 적하수오), VI군(1% cholesterol, 1% 적하수오)에서 유의적으로 감소하였다. 장기무게는 SD rat의 간 무게가 cholesterol 식이군(II, V, VI) 모두에서 정상식이보다 유의적으로 증가하였으나 신장과 비장의 무게는 유의적인 차이를 나타내지 않았다. 혈청 내 포도당 농도는 정상군과 1% cholesterol 식이군 모두 0.5%, 1% 적하수오를 식이로 섭취시킨 그룹에서 유의적으로 감소하는 경향을 나타냈으며, 총 cholesterol과 HDL-cholesterol, LDL-cholesterol 모두에서 유의적인 차이는 나타나지 않았으나 총 cholesterol과 LDL-cholesterol은 수치상 감소하는 경향을 나타내었다. 하지만 비율로 보았을 때 적하수오를 보충급여한 군의 HDL-cholesterol 비율이 LDL-cholesterol 비율보다 유의적으로 증가하는 경향을 나타냈고 동맥경화지수 또한 적하수오 보충 공급한 그룹에서 낮아지는 것을 확인할 수 있었다. 혈중 중성지방의 농도는 일반식이군과 1% cholesterol 급여군 모두에서 적하수오 추가 급여군이 유의적으로 감소하는 경향을 나타냈고 ALT와 AST 활성은 유의적 차이를 나타내지 않았다. 본 실험의 결과에서 적하수오는 혈청 내 포도당 농도를 유의적으로 감소시켰다. 또한 중성지방의 농도도 유의적으로 감소시켰으며, HDL-cholesterol 비율이 LDL-cholesterol 비율보다 유의적으로 증가하는 경향을 나타냈고, 동맥경화지수 또한 적하수오 보충 공급한 그룹에서 낮아지는 것으로 보아 적하수오가 혈관계 장애로 인해 발병되는 고혈압, 당뇨, 뇌혈관질환, 동맥경화증과 같은 질환을 예방하는데 영향을 미칠 것으로 생각되며 기능성식품소재로서의 가능성이 기대된다.

  • The experiments were performed to investigate the effects of protein and protein hydrolysates on lipid metabolism in the hyperlipidemic/hypercholesterolemic rat model induced by feeding fat-enriched diet. In Except 1 male rats were fed four semi-purified high fat and cholesterol diets that contained different nitrogen source, casein(C), casein hydrolysate(CH), corn gluten(G) and corn gluten hydrolysate(GH), for 6 weeks. In Expt. 2 rats were fed high fat and cholesterol diet for 4 weeks to induce hyperlipidemia and hypercholesterolemia. Then the rats were divided into 4 groups and were fed the four kinds of above experimental diets for 4 weeks consecutively. The contents of total lipid , cholesterol and triglyceride in blood, liver and feces were determined. Serum lipid concentrations of CH, G and GH were significantly lower than that of C. Serum cholesterol concentrations of hydrolysate groups(CH and GH) were significantly lower than those of intact protein groups(C and G). Serum HDL -cholesterol concentration tended to increase by hydrolysate intake. The total lipid, cholesterol contents in liver showed similarity results as above. Fecal lipid excretions of CH, G, and GH groups were significantly higher than that of C group. These results indicate that hypolipidemic and /or hypocholesterolemic effect of corn gluten or protein hydrolysates were detected in the process of inducing hyperlipidemia by high-fat and cholesterol diet or after inducing hyperlipidemia.

  • In order to study the effects of Cervi pantotrichum on hyperlipidemia, we divided the rats into three groups (normal group, control group & sample group) and perfomed the experimental research. Hyperlipidemia rat was induced by olive oil $1m{\ell}$(involved cholesterol 0.05g)/1200g for 10 days. The sample group was administerd the extract of Cervipantotrichum 10.8mg/200g for 5 days. and control group was administerd equal dose of saline. And then we measured the amount of serum total cholesterol, triglyceride, HDL-cholesterol, and phospholipid. Cervi pantotrichum showed decreasing effects on total cholesterol, LDL-cholesterol and phospholipid level, and increasing effects on HDL-cholesterol level in serum significantly. According to the above results, Cervi pantotrichum showed significant decreasing effects on hyperlipidemia, and it is considered that it is appropriate to apply for hyperlipidemia.

  • Hyperlipidemia is one of dangerous factors causing the arteriosclerosis. For the study of Cheunggansoyosan-gamibang( CGSYS) on antihyperlipidemic effect, we had fed mice divided to three groups (basal diet, hyperlipidemic diet, hyperlipidemic diet + CGSYS), and observed the change of weight, total cholesterol. triglyceride, HDL-cholesterol. LDL-cholesterol. sGOT, sGPT on the serum per every 7days for 6weeks. Also to compensate for the results above, we had tested rat liver. The results of this Study were obtained as fallows ; 1. Cholesterol change on blood was decreased by CGSYS. 2. Total cholesterol. triglyceride and LDL-cholesterol were significantly decreased by CGSYS. 3. HDL-cholesterol was significantly increasd by CGSYS. 4. sGPT was significantly decreased by CGSYS. 5. sGOT was not changed by CGSYS. 6. In case of supplying CGSYS. fatty degeneration was not observed in liver portal area. This study suggests that Cheunggansoyosan-gamibang was significant effect with hyperlipidemia.
