  • The antihepatic and hypolipidemic activities and total lipid levels of water extract of Plantaginis Herba, used for respiratory and renal disorder in folk medicine, were evaluated in streptozotocin-induced diabetic rats. Diabetes was induced by a single injection of streptozotocin (50 mg/kg, i.p.). Water extract of Plantaginis Herba recovered enzyme activities such as GOT, GPT, ALP and LDH increased by streptozotocin (STZ) treatment. This crude drug also suppressed the enhanced production of lipid in hyperglycemia. These results strongly suggest that Plantaginis Herba be a promising liver-protective and hypolipidemic agent.

  • In this experiment, we investigated the hypolipidemic and antithrombotic effects of rats fed diets with different common oils in Korea for different feeding periods(4 weeks or 12 weeks), using Korean sesame oil, perilla oil, rice bran oil and mixed oil. W-3/w-6 ratio of each group was 0.001, 1.44, 0.03 and 0.112, respectively. P/S ratio of each group was 9.64, 10.49, 5.58 and 1.68, respectively. The result were as follows: 1) According to the age, body fat accumulation was increased. 2) Perilla oil(w-3 rich) decreased total lipid, triglyceride and total cholesterol, and increased HDL/total cholesterol ratio. 3) With regard to the compositono of platelet fatty acids, Perilla oil increased w-3/w-6 ratio of the platelet. Perilla oil lengthened bleeding time and decreased MDA(MalonDAdehyde) formation which determined in place of Thromboxane A2(TXA2) in platelet. This result can suggest that linoleic acid of perrilla oil seem to supress the conversion of linoleic acid to arachidonic acid(AA 20:4, w-6) and eicosapentaenoic acid(EPA, 20:5, w-3) trannnsformed from linolenic acid to suppress the conversion of arachidonic acid to TXA2. Since TXA2 is platelet-aggregating and vasoconstricting agent, the reduction of TXA2 tgeneration by platelet with increased linolenic acid intakes shows prologed bleeding time. In conclusion, w-3 rich perilla oil has strong hypolipidemic and antithrombotic effects by changing fatty acid profiles of the platelet.

  • This study investigated the hypolipidemic and antithrombotic effects of linolenic acid derived from Korean perilla oil. The experimental rats(male, Sprague-Dawley) were divided into 5 groups using a Randomized Complete Block Design and fed one of the five following diets : DO*/O#. D4/O, D4/4, D4/8, or D4/20(D*/# represents the ratio of linoleic to linoenic acid as the percentage of total dietary energy intake) for 4 or 8 months. Bleeding time and whole blood clotting time were determined and the composition of serum and platelet lipids analyzed. Comparisons from the DO/O to the D4/20 group showed that serum lipids (total lipid, triglyceride, total cholesterol, and HDL-cholesterol) gradually decreased with increasing linolenic acid intake - the hypolipidemic effect. The composition of platelet fatty acids[the ratio of eicosapentaenoic acid(EPA)/arachidonci aci(AA)] increased gradually with increasing linolenic acid intake. Higher linolenic acid intake increased bleeding time and whole blood clotting time, and decreased malondialdehyde(MDA) production in the platelets, though no significant differences. These results suggest that linolenic acid derived from perilla oil appears to suppress the conversion of linoleic acid to AA and the EPA transformed from linolenic acid appears to suppress the conversion of AA to TXA2. Since TXA2 is a platelet-aggregating and vasoconstricting agent, the redulction of TXA2 released by platelets with increasing intake of perilla oil containing a lot of linolenic acid confers an antithrombotic effect.

  • Obesity is frequently associated with metabolic disease. This study showed whether fenofibrate, a hypolipidemic agent, swimming and swimming combined with fenofibrate (: combination) regulate obesity, and whether combination is more effective than fenofibrate on regulation of obesity in high-fat diet-fed mice for 8 weeks. Both fenofibrate and swimming decreased obesity-associated factors such as body weight, adipose tissue mass, serum lipid levels and adipoctye size, compared with control mice. When mice were concomitantly treated with fenofibrate and swimming, combination reduced further the inhibitory effects on obesity-associated factors, compared with fenofibrate. Both fenofibrate, swimming and combination decreased serum glucose levels, compared with control mice. The evidence is presented herein that combination were effective to control obesity and serum glucose levels, suggesting that swimming combined with fenofibrate might contribute to inhibition of high-fat diet fed-induced metabolic syndrome.

  • The effect of buckwheat dietary fiber (BDF) as hypolipidemic and antioxidant agent were determined in C57BL/6 mice fed a high fat diet (HFD) with different doses of 500 (low, BDF-L) or 1,000 (high, BDF-H) mg/kg of body weight, compared with the HFD-diet control group (HFD). The negative control group (ND) was fed the basal diet. Body weights in the BDF-L and BDF-H groups were significantly decreased as compared to those in the HFD group (p<0.05). BDF also improved the lipid profile in a dose-dependent manner; serum lipid profiles and levels of insulin, glucose, and free fatty acid were significantly decreased in the BDF-L and BDF-H groups, whereas HDL-C and adiponectin significantly increased as compared to the HFD group (p<0.05). Meanwhile, BDF lowered serum malondialdehyde (MDA) in comparison with the HFD group (p<0.05). The results demonstrate that the intake of BDF might prevent obesity and its related metabolic disorders by inducing dyslipidemia and oxidative stress.

  • Guggulsterone, a hypolipidemic natural agent, is produced in resin canals of the plant Commiphora wightii. In this study, the stimulatory effects of growth retardants [ALAR (N,N-dimethylaminosuccinamic acid) and CCC (chlormequat chloride)] and fungal elicitor on guggulsterone accumulation in cell cultures of C. wightii are reported. CCC at $1\;mg\;l^{-1}$ enhanced guggulsterone content (${\sim}123\;{\mu}g\;l^{-1})$ when added on the fifth day after inoculation, while ALAR at $2.5\;{\mu}g\;l^{-1}$ increased guggulsterone content (${\sim}116\;{\mu}g\;l^{-1}$) when added on the tenth day. In a two-stage fed-batch process, combined treatment with fungal elicitor and growth retardant caused a significant increase (${\sim}353\;{\mu}g\;l^{-1}$) in guggulsterone content in cell cultures after 17 days of growth. This represents an approximately fivefold increase over the guggulsterone contents in initial cultures of this plant.

  • To search for the anti-diabetic principle from the stem bark of Kalopanax pictus, seven kinds of chemical constituents including hederagenin glycosides and phenolic glycosides wre isolated. The anti-diabetic evaluation of these isoltes in the streptozotocin-induced diabetic rats exhibited that kalopanaxsaponin A has a potent anti-diabetic activity in contrast to a mild activity of hederagenin. In addition, significant hypocholesterolemic and hypolipidemic activities of kalopanaxsaponin A and hederagenin were observed. The structure-activity relationship of kalopanaxsaponin A was also investigated in the present work.

  • This study investigated the effect of dietary taurine supplementation on the plasma and liver lipid concentrations in lats fed a cholesterol free diet Twenty male-Sprague-Dawley rats(body weight $200{\pm}10g$) were divided into two groups, the control and taurine group(2% taurine supplemented in their diet). All the rats were fed on the experimental diet and deionized water for 6 weeks libitum. There were no significant differences body weight gain, food intake and the food efficiency ratio between the control and experimental groups. The rats fed the taurine diet had a significantly lower triglyceride and AI(athrogenic index) than those fed the control diet The liver total cholesterol (p<0.05) and triglyceride levels(p<0.01) were significantly lower in the rats fed the taurine diet than in those fed the control diet. These results suggest a possible role of taurine as a hypolipidemic agent in male rats fed a cholesterol free diet.

  • There are many synthetic chemicals, such as di(2-ethylhexyl) phthalate (DEHP) and dibutyl phthalate (DBP), used in chemical reaction processes in industry. The establishment of toxicity and detection of synthetic chemicals that may pose a genetic hazard in our enviornment is subjects of great concern at present DEHP, a ubiquitous phthalate plasticizer, induces a wide range of developmental and reproductive toxicities in mammals. DEHP belongs to the large diverse class of peroxisome proliferator compounds, which include herbicides, hypolipidemic drugs. DBP is a plasticizer used to products containing nitrocellulose, polyvinyl acetate, and polyvinyl chloride such as food wraps and blood bags. DBP is also used in cosmetics as a solvent and fixative for perfumes, a suspension agent for solids, an antifoamer, a skin emollient, and hair spray The present study was performed to examine patterns of gene expression in MCF-7 cells following DEHP and DBP exposure. Changes in gene expression were determined by microarray analysis using KISTCHIP-400 including 401 endocrine related genes based on public database and research papers. Of the genes analysis, we determined that genes detected by array showed a 2-fold or greater change in their expression level(increase or decrease). The results of this study demonstrate that a number of genes were differentially expressed in MCF-7 cells but these changes were not significant. Therefore, we keep going this study using microarray analysis and future studies will examine changes of gene expression on time-course and does treatment in variable cell lines.

  • In this study, we evaluated the hypolipidemic and antioxidative effects of biotransformed soybean powder (BTS; Phellinus baumii-fermented soybean) on lipid metabolism in rats. Sprague-Dawley (SD) male rats were divided into basal diet group (BA), high fat diet group (HF), high fat diet containing 10% BTS group (10 BTS), and high fat diet containing 20% BTS group (20 BTS). Changes in the content of various isoflavones, including daidzein and genistein, within the soybean after fermentation to BTS were investigated. The levels of daidzein and genistein were $149.28{\mu}g/g$ and $364.31{\mu}g/g$, respectively. After six weeks experimental period, Food efficiency ratio in the 10 and 20 BTS group was significantly lower than the HF group (P<0.05). Total serum levels of cholesterol, triglycerides, low-density lipoprotein cholesterol, and atherogenic index ratio in the 10 or 20 BTS group were significantly lower than the HF group. The levels of alanine aminotransferase, aspartate aminotransferase and thiobarbituric acid reactive substance were significantly lower in the groups that received 10% and 20% BTS than the HF. The activities of SOD and CAT were significantly higher in the 10 and 20 BTS group than the HF group. The activity of XO in the 10 and 20 BTS group was significantly lower than in the HF group by 20% and 23%, respectively. In conclusion, these data suggest that BTS is an effective agent in improving lipid metabolism and antioxidant enzyme system.
