  • In order to investigate the effect of 'Whangryonhaedok-Tang' on the anti-inflammatory, ileum of mice, blood pressure, blood glucose, total cholesterol and antibacterial activity, those pharmacological actions were conducted. The results of this studies were summarized as follows; Rat hind paw edema induced by acetic acid was inhibited. In mice, tone of intestinal smooth muscle was suppressed with the treatment of sample and intestinal contractions induced by $BaCl_2$ was inhibited. Hypertensive effect was not observed in rabbits but was observed by the water extract of 'Whangryonhaedok-Tang' excluded Phellodendri Cortex in rabbits. The increased blood glucose levels in alloxandiabetic rabbits were significantly decreased by the oral administration of the sample I after 6 days. The total cholesterol levels in alloxan-induced rabbits were significantly decreased by the oral administration of the sample I after 9 days. Antibacterial activity was observed. In addition, we thought the pharmacological actions were significantly noted by the sample III (Methanol soluble fraction) because of the purification of effective components.

  • As the average span of human life is continuously increasing, especially the old aged groups, are suffering from various chronic and critical diseases e.g. cardiovascular diseases, coronary heart disease, diabetes, atherosclerosis and alzheimer's etc. However, effective and safe treatment methods have not yet been investigated threathening old aged groups. This research was planned to isolate compounds with the therapeutic potential for the above mentioned chronic diseases from the mulberry leaves. Biological screenings were carried out for the following categories; anti-atherogenic, anti-diabetic and antihypertensive effects. The results were as follows; Mulberry leaves, 20% $\alpha$-treated Gaelyrangppong showed significant 81% of blood glucose lowering effects in alloxan-induced hyperglycemic mice. Particularly, butanol-soluble fractions of mulberry leaves showed the more significant hypoglycemic activity than other fractions in alloxan induced hyperhlycemic mice. Also in the group given 1g/kg doses of extract of mulberry leaves, total cholesterol level was decreased significantly by as much as 49% in hyperlipidemia-induced rats. In Mulberry leaves post-treated group, the atheroscelosis index, HDL-cholesterol/Total-cholesterol, was increased significantly by as much as 91%.

  • This study was performed to observe the effects of the feeding physiological activity substance in Cordyceps militaris hot-water extract intake on the improvement of lipid components and metabolic enzyme activities in the serum of dietary hyperlipidemic rats (SD strain, male) fed the experimental diets for 5 weeks. The concentrations of cholesterol (total cholesterol, ${\beta}$-lipoprotein, LDL-cholesterol, free cholesterol and cholesteryl ester), atherosclerotic index, triglyceride (TG), phospholipid (PL) and blood glucose in sera were remarkably lower in the Cordyceps militaris extract intake group than in the hyperlipidemic rats. In the ratio of HDL-cholesterol concentration was higher percentage in the Cordyceps militaris extract intake group than in the hyperlipidemic rats. The activities aminotransferase (AST, ALT) in sera were rather lower in the Cordyceps militaris extract administration than in the hyperlipidemic rats. From the above research, Cordyceps militaris extract were effective on the improvement of the lipid compositions in sera of dietary hyperlipidemic rats.

  • The aim of this study was to investigate the anti-inflammatory and anti-oxidant activity of Ligularia fischeri leaf extract on adjuvant induced arthritis in experimental mice. The oral administration of the L. fischeri leaf extract (LF), at doses of 100 and 200 mg/kg body weight once a day for 3 weeks, significantly reduced hindpaw swelling and the production of inflammatory cytokines (tumor necrosis factor(TNF)-${\alpha}$, interleukin(IL)-$1{\beta}$, and IL-6). Treatment with LF (100 mg/kg) also decreased the serum levels of triglyceride and low density lipoprotein(LDL)-cholesterol, and increased high density lipoprotein(HDL)-cholesterol contents compared with those of a control group. The induction of arthritis significantly increased oxidized proteins such as protein carbonyl, advanced oxidation protein products, and advanced glycation end-products in the lung, heart, and brain. Treatment with LF for 3 weeks reduced the levels of oxidized proteins. These results suggest that L. fischeri extract might be beneficial in the treatment of chronic inflammatory disorders.

  • This study was designed to determine possible weight loss effects of Hangbisan, an oriental medicine, on Sprague-Dawley (SD) rats. SD rats that were fed a high-fat diet for 6 weeks to induce obesity and subsequently fed with a basic diet containing 10%(w/w) Hangbisan or 10%(w/w) cellulose for 8 weeks. The Hangbisan fed rats demonstrated a significantly (p<0.05) reduced weight gain compared to the cellulose fed rats as well as a reduced level of plasma cholesterol and triglycerides and an increased level of (HDL)-cholesterol. These results suggest that dietary Hangbisan has an anti-obesity effect in the high-fat diet-induced obesity (DIG) rat and therefore a potential use as an anti-obesity agent in the application of oriental medicine compounds.

  • 황기열수추출물(WEH)과 홍국 70% 에탄올추출물(EEB) 및 Monascus pilosus 액침배양액(LBK)을 동결건조한 등량 혼합물을 일반 베이스소스에 0.225% 혼합한 황기홍국소스(HBS)에 침지한 계육의 식이가 고지방-고콜레스테롤 병행식이 흰쥐의 체중, 장기중량, 혈청지질 함량에 미치는 영향을 조사하였다. 실험군은 정상군(NC), 고지방-고콜레스테롤 대조군(HFC), 고지방-고콜레스테롤 식이에 베이스소스를 처리한 계육을 15% 첨가한 식이군(HFC-BS) 및 고지방-고콜레스테롤 식이에 황기홍국소스를 처리한 계육을 15% 첨가한 식이군(HFC-HBS)으로 구분하여(5 마리/군) 5주간 사육하였다. 식이섭취량은 HFC-HBS군이 HFC 및 HFCBS군에 비하여 높았으나 식이효율과 사육후의 체중은 낮아 체중감소효과가 확인되었다. ALT 및 AST의 활성도 정상군에는 미치지 못하나 HFC군 및 HFC-BS군에 비하여 현저한 감소를 보였다. HFC-HBS군은 HFC-BS군에 비하여 혈청 triglyceride 함량은 34.06%, total cholesterol 함량은 6.28% 및 LDL-cholesterol 함량은 31.00%가 감소하였으며 HDL-cholesterol 함량은 1.72배 증가되었고 동맥경화지수는 2.52배 감소하였다. 간 조직의 총 지질, 중성지질 및 총콜레스테롤 함량도 HFC-HBS군이 HFC-BS군에 비하여 각각 9.53%, 5.25% 및 22.20%가 감소되었다. NC군은 정상적인 간 조직구조를 나타낸 반면 HFC군은 거의 모든 간세포가 multiple micro vesicles 형태의 지방을 함유하는 것으로 나타났다. 또한 HFC-BS군에서는 HFC군과 비교해 볼 때 소적형 지방축적은 감소되었으나 염증세포와 쿠퍼세포가 활성화된 모습을 보인 반면 HFC-HBS군은 HFC-BS군과 비교해 볼 때 간 실질세포 내 지방들은 아주 작은 포말형으로 나타나며 정상적인 간 실질세포의 형태가 잘 나타나 고지방-고콜레스테롤 식이로 인한 간세포 손상을 크게 완화시킨 것으로 사료된다.

  • Objectives : Phyllostachys pubescens and Scutellaria baicalensis are considered to be effective in promoting blood circulation in traditional medicine. In this study, we examined whether a mixture of P. pubescens leaves and S. baicalensis root (BS21) had any anti-obesity, anti-hyperlipidemia, or anti-hyperuricemia effects and the possible mechanisms of action. Methods : We examined the effects of BS21 in high-fat diet (HFD)-induced obese mice. Mice were fed HFD with BS21 (75, 150, or 300 mg/kg) or Garcinia cambogia extracts (245 mg/kg) as a positive control for 8 weeks. At the end of 8 weeks, body weight, liver and adipose weight, adipocyte size, plasma lipid profiles, adipokine and uric acid levels, and adipose tissue expression levels in obesity and uric acid production-related genes were examined. Results : BS21 decreased body weight gain, white adipose tissue, liver weight, adipocyte size, and liver triglyceride accumulation. It also reduced levels of plasma glucose, triglycerides, non-esterified fatty acids, total cholesterol, low-density lipoprotein cholesterol, alanine transaminase, leptin, and uric acid. In contrast, BS21 increased adiponectin levels. Furthermore, BS21 decreased the expression levels of adipogenesis-related genes, such as peroxisome proliferator-activated receptor γ, sterol regulatory element binding protein-1c, and fatty acid synthase, as well as xanthine oxidoreductase, which is involved in uric acid production. Conclusions : These results suggest that BS21 may exert anti-obesity, anti-hyperlipidemia, and anti-hyperuricemia effects in HFD-induced obese mice by regulating the expression of xanthine oxidoreductase and adipogenesis-related genes.

  • Ginkgo biloba extract (EGb 761) is a standardized extract of Ginkgo biloba leaves and has anti- atherosclerosis properties. Many patients with atherosclerosis disorders take Ginkgo biloba extracts to supplement current therapy. In addition, normal healthy individuals also take Ginkgo biloba extracts for prophylactic purposes. However, it is unknown whether supplementation of Gingko biloba extracts in healthy individuals offer a benefit. In this study, we assessed whether EGb 761 could provide beneficial effects on serum cholesterol levels in normal mice. Wild-type C56Bl/6 mice were orally administered EGb 761 at 25 mg/kg (Group 3) or 50 mg/kg (Group 4) every other day for 40 days. We found that the serum levels of HDL-cholesterol (HDL-C) were significantly increased in EGb 761 and lovastatin treated groups. Treatment with EGb 761 and lovastatin resulted in reduced serum total cholesterol and LDL-cholesterol (LDL-C) compared to control group. Serum lecithin cholesterol acyltransferase (LCAT) levels were higher in EGb 761 and lovastatin treated group compared to the control group. However, no difference was observed in serum APO A-I levels between the control group and treatment group. These results suggest that EGb 761 can increase HDL-C resulting in increased serum LCAT levels.

  • BACKGROUND/OBJECTIVES: Obesity is a global health problem of significant importance which increases mortality. In place of anti-obesity drugs, natural products are being developed as alternative therapeutic materials. In this study, we investigated the effect of Brassica juncea L. leaf extract (BLE) on fat deposition and lipid profiles in high-fat, high-cholesterol diet (HFC)-induced obese rats. MATERIALS/METHODS: Male Sprague-Dawley rats were divided into four groups (n = 8 per group) according to diet: normal diet group (ND), high-fat/high-cholesterol diet group (HFC), HFC with 3% BLE diet group (HFC-A1), and HFC with 5% BLE diet group (HFC-A2). Each group was fed for 6 weeks. Rat body and adipose tissue weights, serum biochemical parameters, and tissue lipid contents were determined. The expression levels of mRNA and proteins involved in lipid and cholesterol metabolism were determined by reverse transcription polymerase chain reaction and western blot analysis, respectively. RESULTS: The HFC-A2 group showed significantly lower body weight gain and food efficiency ratio than the HFC group. BLE supplementation caused mesenteric, epididymal, and total adipose tissue weights to decrease. The serum levels of triglyceride, total cholesterol, and low-density lipoprotein cholesterol were significantly reduced, and high-density lipoprotein cholesterol was significantly increased in rats fed BLE. These results were related to lower glucose-6-phosphate dehydrogenase, acetyl-coA carboxylase, and fatty acid synthase mRNA expression, and to higher expression of the cholesterol $7{\alpha}$-hydroxylase and low density lipoprotein-receptor, as well as increased protein levels of peroxisome proliferator-activated receptor ${\alpha}$. Histological analysis of the liver revealed decreased lipid droplets in HFC rats treated with BLE. CONCLUSIONS: Supplementation of HFC with 3% or 5% BLE inhibited body fat accumulation, improved lipid profiles, and modulated lipogenesis- and cholesterol metabolism-related gene and protein expression.
