This study was performed to investigate the effects of cell-wall broken spores of Ganoderma lucidum on the lipid accumulation and body weight reduction in C57BL/6J mice. Six-week-old C57BL/6J mice were randomly divided into 5 groups and assigned to one of these groups; normal chew diet(Nor) group, high-fat diet(HFD) group, HFD plus spores of Ganoderma lucidum 800 mg/kg/day (HFD + GS/B) group, HFD plus cell-wall broken spores of Ganoderma lucidum 400 mg/kg/day (HFD + BGS/A) group and finally HFD plus cell-wall broken spores of Ganoderma lucidum 800mg/kg/day (HFD + BGS/B). The experimental groups which were treated oral co-administration with cell-wall broken(or original) spores of Ganoderma lucidum and HFD significantly attenuated accumulative body weight gain, compared with HFD group. Administration of these experimental materials also resulted in significant reduction not only the serum levels of total cholesterol, homocysteine but also the lipid accumulation in liver tissue. But in the almost of results the cell-wall broken spores of Ganoderma lucidum were evaluated superior than the original one. These results indicate that cell-wall broken spores of Ganoderma lucidum may inhibit the lipid accumulation in blood as well as liver tissue. Therefore it may be a valuable candidate for the therapy preventing obese induced hyperlipidemic symptoms.

Objectives : This study was aimed to investigate the effect of ACLL extract (Artemisia capillaris Thunb, Curcuma longa L, Lycium chinense, Ligustrum lucidum Aiton complex extract) in a dyslipidemia animal model induced by a high-fat diet. Methods : ACLL extracts was administered at 200 mg/kg, and 400 mg/kg to Apoe mice, where arthritis was induced by high cholesterol diet. After mice were treated with GO for 4 weeks, we measured AST, ALT, BUN and lipid levels (total cholesterol, HDL cholesterol, LDL cholesterol, triglyceride), atherogenic index(AI) and cardiac risk factor(CRF). Results : Serum AST, ALT, creatinine, BUN levels were not changed by ACLL extract do not show any toxic effects. Also, ACLL extract groups were found to have atherogenic Index and cardiac risk factor as well as lipid metabolism improvement (total cholesterol, LDL cholesterol and triglyceride decrease). Conclusions : We suggest that ACLL extract may have the control effects of Dyslipidemia by improving lipid metabolism.

This research was designed and implemented to evaluate how the composition of yaksuncha can affect the health of individuals suffering from diet-related diseases such as obesity and hyperlipidemia by prescribing Yaksun as a nutritional supplement with daily meals. The yaksunucha was prepared as Koekac, Sansa, Heshouwu and Woolong tea and the tea's effects on serum lipids and oxidative stress were evaluated by clinical procedures. The yaksuncha significantly increased HDL-cholesterol and decrease of LDL-cholesterol concentrations in serum. It also had significant effects on decreasing oxidative stress and homocystein levels. The physical characteristics of the yaksunucha were also examined, showing. Brix, pH and titratable acidity values of 1.4, 5.50 and 0.05% respectively. It is thought that scientific and objective evaluations were completed on the components of the yaksuncha prescription. Thus one can concluded that the components could be applied not only in the form of tea, but also various food. The data derived from this study provides basic information that will aid in the application of oriental medicinal resources to other foods as well as facilitate the study of medicinal herbs within the field of functional food research, which already draws sizable attention worldwide.

남해안에서 다량 생산되고 있는 김(Porphyra yezoensis)의 생리활성 물질은 porphyran을 분리 추출한 후, 흰쥐에서 고지혈증 및 고 콜레스테롤혈증을 유발시켜 간장의 항산화 효소활성 및 면역능을 측정하였다. 간의 효소활성 측정을 위해 Sprague-Dawley계 흰쥐를 9마리씩 5군으로 나누어 1군은 정상군, 2군은 대조군(고지혈증 유발군), 3, 4 및 5군은 porphyran 급이군으로서 대조군에 porphyran을 각각 1%, 5% 및 10%의 비율로 사료에 첨가하여 4주간 사육하였다. 면역능은 Balb/c female mouse를 이용하여 3마리씩 4군으로 대조군 및 porphyran 1%, 2% 및 5%로 조제된 시료를 실험동물에게 2일에 1회 1mL씩 복강 주사를 연속적으로 20일간 투여한 후 비교하였다. 혈청중의 alanine aminotransferase(ALT), aspartate aminotransferase(AST), alkaline phosphatase(ALP) 및 lactic dehydrogenase(LDH) 활성은 대조군에 비해 porphyran 급이군에서 낮았으며, porphyran의 급이 수준이 증가할수록 대조군에 비해 유의하게 낮은 경향을 보였다. 간장의 superoxide dismutase와 catalase활성은 정상군에 비하여 대조군이 유의하게 높았으나, 대조군에 비해 porphyran 급이군에서는 낮았으며, 특히 10% porphyran 급이군에서는 정상군 수준으로 유의하게 감소되었다. TBARS 역시 대조군에 비해 porphyran 급이군 모두 유의하게 감소하였으며, 정상군 수준이하로 감소되었다. Interleukin-1농도는 porphyran 2% 및 5%를 투여한 흰쥐의 혈청에서 정상군보다 각각 26.81%, 77.95%의 증가를 나타내었으나, Interleukin-2는 감소하였다. 본 연구 결과에서 porphyran 급이는 고지혈증을 유발한 흰쥐에서 과산화물 농도를 저하시켜 항산화 효소활성을 낮추었으며, 면역능에서 일정한 현상은 나타나지 않았다.

Pharmacological effects of water extracts of Lycii Fructus, Lycii Folium and Lycii Cortex Radicis from Lycium chinensis were investigated. Lycii Folium significantly protected the hepatic function from damages orally caused by $CCl_4 $administration in mice and had a strong hypoglycemic effect in hyperglycemic mice induced by streptozotocin. Lycii Fructus decreased the blood pressure rise associated with the growth of normal rats. Lycii Cortex Radicis had a strong hypoglycemic effect in hyrerglycemic mice induced by streptozotocin. Also, hypolipidemic effects in hyperlipidemic rats induced by 1% cholesterol fed-diet and 75% fructose were significantly observed by oral administration of water extracts of Lycii Fructus, Lycii Folium and Lycii Cortex Radicis.

The inhibitory effect of polyphenol extracts (Seapolynol$^{TM}$, SPN) of the marine brown algae Ecklonia cava and dieckol, a major component of SPN, on hyperlipidemia was investigated in ICR mice fed a high-fat diet (HFD) for five weeks. For analysis of the anti-hyperlipidemic effects of SPN and dieckol, these two agents were given orally on a daily basis to HFD-fed mice for four weeks, starting one week after the beginning of HFD feeding. Groups administered with SPN as well as dieckol showed lower body weight gains than the HFD only group. Administration of SPN and dieckol also resulted in a significant reduction of the level of total cholesterol (TCHO), triglyceride (TG), and low-density lipoprotein (LDL) cholesterol in the serum of HFD-fed mice. In Oil Red O staining using 3T3-L1 preadipocytes, it was shown that both SPN and dieckol markedly inhibited lipid accumulation of 3T3-L1 cells. Furthermore, SPN and dieckol (50 ${\mu}g$/mL) significantly inhibited 3-hydroxyl-methyl glutaryl coenzyme A (HMGCoA) reductase activity in vitro. Taken together, these results suggest that polyphenols of Ecklonia cava (SPN) and dieckol reduce body weight gain and fat accumulation in HFD-induced obese mice, and that their hypolipidemic effect is related to the inhibition of adipogenesis of adipocytes and HMGCoA reductase activity.

Antiplatelet aggregation, anticoagulant and lipid-lowering drugs are clinically widely used for secondary preventive purpose in the cardiovascular patients, but there is no primary preventive agents to prevent these diseases. With the aim of developing effective primary agents for cardiovascular diseases, we tried to formulate an optimized mixture of natural plants extract containing Theae sinensis, Camelliae sinensis, Vitis vinifera, Gingko folium and curcuminoids from Curcuma longa and to evaluate its anti-thrombotic and anti-hypercholesterolemic effects in vivo. The inhibitory effect of curcuminoids on vascular smooth muscle cell proliferation and migration were also investigated in vitro. in the animal experiments treated with hyperlipidemic diet, oral treatment of curcuminoids and natural plants extracts mixture (100 mg/kg) into male Sprague Dawley rats for 7 week simultaneously inhibited platelet aggregation as well as improved lipid profile in the blood. Compared to control group, both of curcuminoids-treated and mixture-treated groups revealed significantly decrease of total cholesterol (24.4%, 28.6%), free cholesterol (25.1%, 24.0%), cholesterol ester (14.6%, 29.0%), LDL-cholesterol (27.0%, 32.0%) and triglyceride (15.0%, 31.0%), respectively. However, both groups showed increase of HDL-cholesterol (46.6% and 51.5%) . In particular, atherogenic index of curcuminoids and mixture treatment group was significantly decreased to 47.0% and 56.0%, respectively. Furthermore, oral treatment of curcuminoids and mixture significantly inhibited collagen-induced platelet aggregation (21.1% and 29.1%, respectively), compared to control group. The anti-thrombotic values of mixture was almost similar to that of aspirin treatment (100 mg/kg) group. These results suggest that the oral treatment of curcuminoids-based natural plant extract mixture improved cardiovascular conditions in hyperlipidemic rats.

The antihyperlipidemic and antioxidant activities of dietary supplementation of sea tangle from Goseong and the alginate-free residue of sea tangle were investigated in Sprague Dawley rats treated with a high-fat diet, streptozotocin, poloxamer 407, and bromobenzene. The alginate-free residue of Goseong sea tangle induced a significant reduction in triglycerides and total cholesterol levels, as well as a significant increase in high-density lipoprotein cholesterol levels. Alginate-free Goseong sea tangle residue reduced the activities of the phase I enzymes aminopyrine N-demethylase and aniline hydroxylase, which had been increased by intraperitoneal injection of bromobenzene. Pretreatment with Goseong sea tangle residue prevented a bromobenzene-induced decrease in epoxide hydrolase activity. Bromobenzene reduced hepatic glutathione content and increased hepatic lipid peroxide levels. Pretreatment with alginate-free Goseong sea tangle residue prevented lipid peroxidation induced by bromobenzene, but pretreatment with Goseong sea tangle did not. These results suggest that Goseong sea tangle residue exerted antihyperlipidemic and antioxidant activities that were higher than those induced by alginate-containing sea tangle. Therefore, the alginate-free residue may contain physiologically unknown active components, other than alginic acid, which may potentially be used to prevent hyperlipidemic atherosclerosis.

Botryosphaeran, a water-soluble exopolysaccharide of the ${\beta}-(1{\rightarrow}3;1{\rightarrow}6)$-D-glucan type that has been isolated from the culture medium of Botryosphaeria rhodina MAMB-05 grown in submerged fermentation using glucose as the sole carbon source, was previously demonstrated to be non-genotoxic in peripheral blood and bone marrow, and exhibited strong anticlastogenic activity. In the present study, the effects of botryosphaeran were investigated in streptozotocin-induced diabetic rats as well as in high-fat diet-fed hyperlipidemic Wistar rats. The plasma glucose level was reduced by 52% in the diabetic group of rats after administration of 12 mg botryosphaeran/kg body weight of the rats (b.w.)/day by gavage over 15 days. A reduction in the median ration intake was accompanied by an increase in the median body weight gain, as well as the efficiency of food conversion. These results demonstrate that botryosphaeran has protective effects by reducing the symptoms of cachexia in Diabetes mellitus. Botryosphaeran administered by gavage at a concentration of 12 mg botryosphaeran/kg b.w./day over 15 days also reduced the plasma levels of total cholesterol and low density lipoprotein-cholesterol by 18% and 27%, respectively, in hyperlipidemic rats. Based on these findings, we conclude that botryosphaeran possesses hypoglycemic and hypocholesterolemic properties in conditions of diabetes mellitus and hyperlipidemia, respectively, and may be used as an oral anti-diabetic agent.
