Effects of prunella vulgaris L., chrysanthemum indicum L. and pueraria Radix on plasma lipid composition and histological consideration were investigated in hyperlipidemic rats. Concentration of plasma ${\beta},-lipoprotein$ showed a tendence to decrease in prunella vulgaris L., chrysanthemum indicum L. and pueraria Radix treatment groups. However these values were showed not significantly different from control group. Concentration of plasma FFA in prunella vulgaris L., chrysanthemum indicum L. and pueraria Radix treatment groups showed a lower values compared to control group and concentration of plasma FFA of prunella vulgaris L. and pueraria Radix treatment group showed a lower values than prunella vulgaris L. and chrysanthemum indicum L. treatment group. Concentration of plasma glucose and triglyceride showed a tendence to decrease in prunella vulgaris L., chrysanthemum indicum L. and pueraria Radix treatment groups. However plasma glucose values showed not significantly different from control group. Plasma total cholesterol concentration showed a low and HDL-cholesterol concentration showed a high in prunella vulgaris L. and pueraria Radix treatment group. However LDL-cholesterol concentrations were not significantly different in treatment groups. Histological consideration of heart, liver and kidney in prunella vulgaris L. and pueraria Radix treatment groups showed a good features in fat accumulation condition than those of other treatment groups. However in the condition of high fat accumulation in tissues, heart, liver and kidney were showed a slight congestion and a bashed cell nucleus.
This study was performed to investigate the effects of ramie (Boehmeria nivea) leaf powder on improvements in lipid metabolism in serum, liver and adipose tissue, and the anti-obesity effect in rats fed a high fat/high cholesterol diet for 4 weeks to induce a hyperlipidemic and obese model rat. Male Sprague-Dawley rats weighting 210 g were divided into four groups; a normal diet group (N), a high fat/high cholesterol diet group (HFC), a high fat/high cholesterol diet with 5% ramie leaf powder group (HFC-RL), and a high fat/high cholesterol diet with 10% ramie leaf powder group (HFC-RH). The body weight gain increased with a high fat/high cholesterol diet, but gradually decreased in the ramie leaf powder fed groups compared with the HFC group. The liver index in the HFC group was highest among the four groups, although the difference was not significant compared with the ramie leaf powder fed groups. The adipose tissues weight in the HFC group was heavier than that of the N group, whereas those of groups fed ramie leaf powder decreased gradually. Alkaline phosphatase activity was not different between the HFC groups, but serum alkaline aminotransferase and lactate dehydrogenase activities decreased significantly after ramie leaf powder feeding. Levels of serum triglyceride, total cholesterol, LDL-cholesterol, atherogenic index and cardiac risk factors tended to decrease in the ramie leaf powder fed groups compared with the HFC group, whereas serum HDL-cholesterol level decreased in the HFC group and markedly increased in the ramie leaf powder fed groups. Levels of triglyceride and total cholesterol in the liver were significantly lower in the ramie leaf powder fed groups than in the HFC group. Levels of triglyceride and total cholesterol in adipose tissues were also lower in the ramie leaves powder fed groups than in the HFC group. The activities of heparinreleasable lipoprotein lipase (LPL) and total-extractable LPL in adipose tissues increased in the HFC group compared to that of the N group, but those of the ramie leaf powder fed groups decreased significantly. These results suggest that ramie leaf powder may improve lipid metabolism in serum, liver and adipose tissue and potentially reduce lipid storage.

Purpose: Our previous study demonstrated that persimmon (Diospyros kaki Thumb.) at different stages of ripening provided different protective effects against high-fat/cholesterol diet (HFD)-induced dyslipidemia in rats. In this study, we compared the metabolites profile and gene expressions related to triglyceride (TG)/cholesterol metabolism in vitro and in vivo after treating with persimmon water extracts (PWE) or tannin-enriched persimmon concentrate (TEP). Methods: Primary and secondary metabolites in test materials were determined by GC-TOF/MS, UHPLC-LTQ-ESI-IT-MS/MS, and UPLC-Q-TOF-MS. The expression of genes related to TG and cholesterol metabolism were determined by RT-PCR both in HepG2 cells stimulated by oleic acid/palmitic acid and in liver tissues obtained from Wistar rats fed with HFD and PWE at 0, 150, 300, and 600 mg/d (experiment I) or TEP at 0, 7, 14, and 28 mg/d (experiment II) by oral gavage for 9 weeks. Results: PLS-DA analysis and heatmap analysis demonstrated significantly differential profiling of metabolites of PWE and TEP according to processing of persimmon powder. In vitro, TEP showed similar hypolipidemic effects as PWE, but significantly enhanced hypocholesterolemic effects compared to PWE in sterol regulatory element-binding protein 2 (SREBP2), HMG-CoA reductase (HMGCR), proprotein convertase subtilisin/kexin type 9 (PCSK9), cholesterol $7{\alpha}-hydroxylase$ (CYP7A1), and low density lipoprotein receptor (LDLR) gene expression. Consistently, TEP and PWE showed similar hypolipidemic capacity in vivo, but significantly enhanced hypocholesterolemic capacity in terms of SREBP2, HMGCR, and bile salt export pump (BSEP) gene expression. Conclusion: These results suggest that column extraction after hot water extraction may be a good strategy to enhance tannins and long-chain fatty acid amides, which might cause stimulation of hypocholesterolemic actions through downregulation of cholesterol biosynthesis gene expression and upregulation of LDL receptor gene expression.

This study was carried out to investigate the effect of Yacon (Polymnia sonchifolia Poepp. & Endl.) powder on cholesterol-lowering and anti-obesity effects in rats fed a high fat-high cholesterol diet for 4 weeks to induce hyperlipidemic and obese rat model. Weight-matched male Sprague-Dawley rats were assigned to four groups according to dietary fat, cholesterol levels and Yacon powder levels. Experimental groups were normal diet group (N), high fat-high cholesterol diet group (HFC), high fat-high cholesterol diet with 5% Yacon powder group (HFC-PSL) and high fat-high cholesterol diet with 10% Yacon powder group (HFC-PSH). The body weight gain and FER were increased by a high fat-high cholesterol diet, but gradually decreased in the Yacon powder fed groups compared with the HFC group. Food intake was lower in HFC groups compared with N group. The liver and adipose tissue weights of HFC group were heavier than those of N group, whereas those of groups administered Yacon powder were gradually decreased. The serum ALT, AST, ALP and LDH activities elevated by a high fat-high cholesterol diet were significantly decreased by Yacon powder administration. Levels of serum total cholesterol, LDL-cholesterol, atherogenic index and cardiac risk factor showed a decreasing tendency in the Yacon powder fed groups compared with HFC group. The serum HDL-cholesterol level decreased in the HFC group and markedly increased in the Yacon powder fed groups. Levels of total cholesterol and triglyceride in liver and adipose tissues were lower in Yacon powder administered groups than those in HFC group. These results suggest that Yacon powder may improve lipid metabolism of serum, liver, and adipose tissue and potentially reduce lipid storage.

This study was conducted to investigate the influence of laminaran from Eisenia bicyclis on serum lipid composition of rats fed high fat and cholesterol diets. Fourty male Sprague-Dawley rats weighing $70{\pm}2.5g$ of 4 weeks old were fed experimental diets for 6 weeks with high fat diet consisting of basal diet plus cholesterol (1%) and lard (10%) for the inducement of hyperlipidemia. The effect of laminaran supplements via drinking waters on serum lipid composition of rat were investigated for 5 weeks by administration of experimental diet group fed basal diet only as normal group, control group fed high fat diet, LL group fed high fat diet plus 0.25% laminaran containing water, and LH group fed high fat diet plus 0.5% laminaran containing water, respectively. As a results of experiments, it was found that LL and LH groups showed significant (p<0.05) decrease in body weight gain and liver weight as compared with control and it may caused by decreased FER. The weight of cecum and adipose tissue (EFP) of LL group showed a significantly (p<0.05) decreased patterns compared with control. It was also found that LL and LH diet groups affects the intestinal length and transit time of rat as significantly (p<0.05) increased in length of intestine and decreased in transit time. In addition, LL and LH diet groups showed a dramatic decrease in triglyceride, total and LDL-cholesterol, and significant increase in HDL-cholesterol compared with control diet group, by which results in decreased in AI. These results indicate that crude laminaran from Eisenia bicyclis has a strong hyperlipidemic and hypercholesterolemic activities in rat fed high fat and cholesterol diet.
The lipid lowering and antioxidant effects of Gansoo(BL18), Pungji(GB20) and Eumnungcheun(SP9) acupuncture in rats fed high fat diet were analyzed in biochemical and molecular biological aspects. The results obtained from this study are as follows : 1. In the body weight reduction, all acupuncture groups showed a high reduction compared to those of control group and in acupuncture groups, Gansoo(BL18) and Pungji(GB20) acupuncture groups showed a high reduction. 2. The concentration of plasma triglyceride, total cholesterol and LDL-cholesterol with acupuncture groups showed a little decrease and in acupuncture groups, Gansoo(BL18) and Pungji(GB20) groups showed a low values compared to those of other acupuncture groups. However, the tendency of HDL-cholesterol concentration showed no significant different. 3. The concentration of plasma ${\beta}-lipoprotein$ and free fatty acids showed a lowest values in the Gansoo(BL18) and Pungji(GB20) acupuncture groups and the glucose concentration showed to decrease in all treated acupuncture groups. 4. The concentration of liver total cholesterol and triglyceride in Gansoo(BL18) and Pungji(GB20) acupuncture groups showed a lower values than those of control group. 5. In all the acupuncture groups, the plasma glutamic oxaloacetic transaminase(GOT) activity showed a little decrease. In the glutamic pyruvate activity(GPT), Gansoo(BL18) and Pungji(GB20) acupuncture groups showed a lower values than those of control groups. However the values of eumneungcheun acupuncture only group showed no significant difference to those of control group. 6. The plasma and liver Thiobabituric acid reactive substance (TBARS) concentration in Gansoo(BL18) and Pungji(GB20) acupuncture groups were a lower than those of control group. However the values of eumneungcheun acupuncture group showed no significant difference to control group. 7. The superoxide dismutase (SOD) activity in Gansoo(BL18) acupuncture group and Glutathione peroxidase (GSH-Px) activity in Gansoo(BL18) and Pungji(GB20) acupuncture groups showed a high values. The catalase (CAT) activity in all the acupuncture groups showed a higher values than those of control group. 8. In acupuncture groups, DNA expression of Apo-B and Apo-E showed a tendency to decrease, however DNA expression of leptin showed no significant difference in all treatment groups. DNA expression of $TNF-{\alpha}$ showed a increase in acupuncture groups. These results indicate that Gansoo(BL18) and Pungji(GB20) (especially Gansoo(BL18)) acupuncture affect the lipid metabolism and showed possibility of lowering adipose tissue mass and lipid peroxidation.
