  • The effects of capsaicin, a pungent principle of hot red pepper, on body fat gain, balance serum lipid values were investigated in rats fed a high-fat(30%) diet. Administration of capsaicin by dietary administration caused a complete cessation of increased in body weight and fat gain induced by the high-fat diet. However, energy intake and body protein gain were not affected by capsaicin. Therefore, the suppression of body fat gain by capsaicn was believed due to an increased in energy expenditure. Simultaneous administration of capsaicin and a $\beta$-adrenergic blocker, propranolo, resulted in the inhibition of changes in body fat gain by capsaicin without remained unchanged, indicating an increase in the number of mitochondria in brown adipose tissue. Therefore, it appears that capsaicin possesses potent body fat suppressive effects mediated by $\beta$-adrenergic stimulation in which brown adipose tissue may be involved. On the other hand, capsaicin had no effects on serum triglyceride, total cholesterol or HDL-cholesterol levels. These results are in contrast to those reported by other investigators. Perhaps expression of the effects of capsaicin on plasma lipids is a rather complicated process, dependent on the type of diet administered, fat content of the diet, period and route of capsaicin administration, and species and strain of animals used.

  • This study was designed to investigate the effect of Codonopsis lanceolata extracts on carbon tetrachloride (CCl₄)­induced hepatotoxicity in rats fed high, medium or low fat diet. The liver weight was increased not by the level of fat in diet but by administration of CCl₄. Activities of serum aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were significantly increased by CCl₄, the activities of AST and alanine aminotransferase (ALT) were significantly decreased in case of CCl₄ treatment with C. lanceolata extracts. In high fat diet with CCl₄ administration, the content of total lipid in liver was significantly increased, which was significantly decreased by the administration of C. lanceolata extracts. Administration of C. lanceolata water extracts remarkably prevented the tissue injury such as lipid degeneration, infiltration of inflanunatory cells and necrosis caused by CCl₄, but those methanol extracts did not affect histopathological changes of the liver as water extract. The data suggest that intake of C. lanceolata extracts would prevent lipid accumulation and hepatotoxicity induced by high fat diet and CCl₄ abministratim, and the water extract of C. lanceolata is supposed to be more effective than those methanol extract.

  • This study investigated the effects of Wolbiga-banha-tang (WBBT) on high fat diet-induced rats. We divided the rats into 4 groups: normal (fed a general-fat diet), control (fed a high-fat diet and no treatment), $WBBT{\times}1$ (fed a high-fat diet and 250 mg/kg of Wolbiga-banha-tang extracts), and $WBBT{\times}2$ (fed a high-fat diet and 500 mg/kg of Wolbiga-banha-tang extracts). We measured the body weight, total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, free fatty acids, total lipids, AST, ALT, and CBC in the serum of the obese rats for 7 weeks. There was a significant decrease in the control group, $WBBT{\times}1$, and $WBBT{\times}2$ in triglycerides and free fatty acids. The results suggest that WBBT is effective for lowering triglycerides and free fatty acids. Therefore, WBBT may be applied to the treatment of lipid metabolism in obesity and further clinical studies are needed.

  • This study was conducted to investigate the cholesterol and Triglyceride (TG) lowering and anti-obesity effects of water extract of vegetable formula (onion 25%, carrot 20%, Cabbage 20%, Sweet Pumpkins 20%, Chinese plum 5%, turmeric 5%, morus leaves 5%, SLS) in mice fed high fat-diet. ICR mice were divided into 3 groups; a normal diet group (ND), a high-fat diet group (HFD), a high-fat diet and SLS with 300 mg/kg treated group (HFD+SLS). Body fat gain was increased by high-fat diet and HFD+SLS group showed a definite weight loss. The total cholesterol level in the HFD+SLS group was 328.4 mg/dl which was 27.4% lower than that in the HFD group and the cholesterol-lowering effect of SLS was confirmed. The HFD + SLS group showed 118.1 mg/dl and the triglyceride level in the serum was decreased by 88.7% compared to the HFD group and SLS significantly decreased blood triglyceride levels. RT-PCR showed that the expression of PPAR-${\gamma}$ and the target gene SCD-1 was inhibited in a dose-dependent manner in the SLS-treated group. These results suggest that the SLS water extract may have a cholesterol and triglyceride-lowering effect and inhibit the expression of PPAR-${\gamma}$ and SCD-1 to have an anti-obesity effect.

  • Black ginseng is produced by a repeated steaming process. The aim of this study was to investigate the anti-obesity effects of black ginseng ethanol extract (BG-EE) in high fat (HF) diet-fed mice. Two groups were fed either a normal control (NC) diet or a HF diet (45% kcal fat). The other three groups were given a HF diet supplemented with 1% BG-EE, 3% BG-EE, and 5% BG-EE for 12 wk. The anti-obesity effects of the BG-EE supplement on body weight, the development of fat mass, and lipid mechanisms were assessed in obese mice. HF-induced hyperlipidemia, fat accumulation in the liver, and white adipose tissues were reduced after BG-EE supplementation. Total fecal weight and the amount of fecal fat excretion also were increased after BG-EE supplementation. These results suggest that BG-EE may be useful to ameliorate HF-induced obesity through the strong inhibition of fat digestion.

  • Dongchunghacho rice, produced by cultivating Dongchunghacho fungus on rice, could be an effective functional food because it offers added value to rice and thus increases rice consumption. However, the physiological effect of Dongchunghacho rice has not been reported yet although there is increasing consumers demand. Therefore, we investigated the effect of Dongchunghacho rice (unpolished rice cultivated with Cordyceps militaris) on lipid metabolism in hyperlipidemic rats. Forty of 8 wk-old male Sprague-Dawley rats were divided into four groups after a 1 week of adaptation period and fed either a normal diet (66% polished rice diet, NC), high fat (12 g/100 g)-high cholesterol (1 g/100 g) diet with 53% polished rice (HC), or high fat-high cholesterol diets supplemented with 30% of the total rice as either unpolished rice (DR) or Dongchunghacho rice (DR). After 4 weeks, rats fed the Dongchunghacho rice diet with high fat and cholesterol had dramatically lower plasma LDL cholesterol concentrations and atherogenic indexes and higher plasma HDL cholesterol levels compared with the rats consuming polished rice or unpolished rice with high fat and cholesterol diet. Dongchunghacho rice led to less total lipid and total cholesterol accumulation in liver. However, these significant reductions in plasma or hepatic lipid profiles were not closely correlated with fecal total lipid or total cholesterol excretion. The plasma concentration of total cholesterol and triglycerides were not affected by Dongchunghacho rice. This hypolipidemic effect of Dongchunghacho rice seemed to be unrelated to unpolished rice itself, because the plasma and hepatic lipid profiles of DR group were not different from that of the HC group. These results suggest that unpolished rice containing cultivated Cordyceps militaris can improve plasma and hepatic lipid profiles in rats fed with high fat-high cholesterol diet.

  • As the obesity has been known to be related with the hyperlipidemia, cardiovascular disease, cerebral apoplexy, fatty liver, and other chronic diseases, recent researches have focused on the functional food materials and their anti-obesity activities. This study was performed to study the effects of vanilloid family capsaicin, major pungent ingredient of hot chillies and peppers, on anti-obesity activities. ICR male mice were fed one of the pellet diet, basal diet, and high fat diet with capsaicin (45 $\mu\textrm{g}$/day) solution for 5 days. Mice in the corresponding control groups were given water for 5 days. In results, capsaicin reduced body weights in any diet groups. Percent weight and cell size of the abdominal white adipose tissue in mice on the high fat diet with capcaicin were significantly lower compared with those in mice on the high fat diet with water. However, percent brown adipose tissue weight per body weight in mice on the high fat diet was not affected by capsaicin. Capsaicin reduced the levels of s-triglyceride and s-total cholesterol in the pellet diet or high fat diet groups. There was no difference in the s-protein levels between the capsaicin group and the control water group. These data indicate that 1) orally administered capsaicin has a reducing effect on the blood triglyceride and total cholesterol levels, and 2) capsaicin has lowering effects on the body weight, percent weight and cell size of the abdominal white adipose tissue.

  • The present study investigated the anti-obesity effects of Mycoleptodonoides aitchisonii (MA) in mice fed a high-fat (HF) diet. Two groups were fed either a normal control diet or an HF (45% kcal fat) diet for 12 weeks and three groups were fed an HF diet supplemented with powdered MA (MAP, 1%, 3%, and 5%) for 12 weeks. The anti-obesity effects of MAP supplementation on body weight, fat mass development, and lipid-related markers were assessed. Consumption of an HF diet resulted in increased body weight, serum lipids, relative adipose tissues weight, and liver fat accumulation. However, administration of MAP significantly decreased body weight gain, food intake, food efficiency ratio, hepatic cholesterol level, and adipose tissue weight in a dose-dependent manner. In addition, treatment with MAP significantly reduced the occurrence of fatty liver deposits and steatosis, and inhibited an HF diet-induced increase in adipocyte size. These results suggest that dietary supplementation with MAP exerts anti-obesity effects and indicate that MAP could be used as a functional food to control obesity.

  • Objectives : It was conducted to experimentally analyze the effects of acupuncture treatment at CV12, ST25, and ST36 on weight, FBCS, fat metabolism, microbiome, and metabolome changes in the general diet rat and the high-fat diet rat. Methods : It was classified into four groups: general diet & non-treatment group (ND), general diet & acupuncture treatment group (ND+AT), high-fat diet & non-treatment group (HFD), and high-fat diet & acupuncture treatment group (HFD-AT). After acupuncture treatment was performed on CV12, ST25, and ST36, changes in body weight, FBCS, fat metabolism, microbiome, and metabolome were analyzed. Results : Compared to the ND group, acupuncture treatment performed on CV12, ST25, and ST36 in the ND+AT group had no significant effect. Compared to the HFD group, CV12, ST25, and ST36 acupuncture in the HFD+AT group reduced weight, fat weight, inflammatory cytokine IL-6 expression, and lipid droplet accumulation in liver tissue. Acupuncture can promote fat metabolism and relieve inflammatory conditions. Differences in diversity between ND and HFD groups were clear in changes in microbiome, fecal metabolites, and serum metabolites. As a result of some microbiome and metabolites involved in fat decomposition, intestinal lipid absorption, and blood lipid concentration control, such as Intestinimonas, Ruminococcus 1, pyroglutamic acid, tryptophan, and inositol, it was observed that the acupuncture treatment effect was evident in the disease-induced imbalance. Conclusions : Acupuncture treatment performed on CV12, ST25, ST36 clearly observed various regulatory actions on obesity induced by high-fat diet, confirming that the action of acupuncture treatment mainly plays a role in controlling an unbalanced state.

  • This study was conducted to examine the effects of dietary xylooligosaccharides on hepatic HMG-CoA reductase activity and morphological exchange of liver in rats fed high fat diet. Sprague-Dawley male rats weighing 100 $\pm$ 10 g were randomly divided into four groups, two normal diets and two high fat diets containing 1% cholesterol and 10% lard. Two normal diets were classified into a basal diet (normal group) and 10% xylooligosaccharide diet (NX group). The high fat diet groups were classified into a HF group without xylooligosaccharides diet and HFX group supplemented 10% xylooligosacchride diet. Experimental diets were fed ad libidum to the rats for 4 weeks and then they were sacrificed. The body weight of high fat diet (HF group) was increased more than that of normal group, but it was significantly decreased by xylooligosacchrides supplementation. The food intake was not significantly different among the all groups. The weight of liver, small intestine and cecum of all xylooligosaccharide supplemented groups were significantly heavier than those of normal and HF groups. The activity of hepatic HMG-CoA reductase, a rate limiting enzyme of cholesterol biosynthesis, in xylooligosaccharide supplemented groups was higher than that of HF group. Light micrographs revealed that the structures of hepatocytes in xylooligosaccharide supplemented groups were preserved well, compared to HF group. The xylooligosaccharide supplementation exerted a lipid-lowering action by decreasing cholesterol and triglycerides contents in hepatic tissue. In conclusion, the activity of hepatic HMG-CoA reductase and damage of liver in rats fed high fat diets were improved by dietary xylooligosaccharides.
