Objectives : Mahuang-Chuanwu(Mahwang-Cheonoh) Pharmacopuncture(MCP) has been used to treat obesity in Clinical Korean Medicine. MCP solution(MCPS) is also expected to have strong anti-obesity activities. However, little is known about the mechanisms of its inhibitory effects on adipocyte differentiation and lipogenesis. Methods : In the present study, we examined the effects of MCPS on differentiation and lipogenesis of 3T3-L1 adipocytes. To elucidate the mechanism of the effects of MCPS on lowering lipid content in 3T3-L1 adipocytes, we examined whether MCPS modulates the expressions of transcription factors to induce lipogenesis and adipogenic genes related to regulate the accumulation of lipids. Results : Our results showed that MCPS significantly inhibited differentiation and lipogenesis of 3T3-L1 adipocytes in a dose-dependent manner. MCPS suppressed the mRNA expressions of cytidine-cytidine-adenosine-adenosine-thymidine(CCAAT)/enhancer binding proteins ${\alpha}$($C/EBP{\alpha}$), C/EBP ${\beta}$, $C/EBP{\delta}$, and peroxisome proliferator-activated receptor ${\gamma}$($PPAR{\gamma}$) genes related to the induction of adipose differentiation. MCPS inhibited the mRNA expressions of adipose-specific aP2, adipsin, lipoprotein lipase(LPL), CD36, TGF-${\beta}$, and leptin genes related to the fat formation. MCPS downregulated the mRNA expressions of liver X receptor(LXR) ${\alpha}$ and fatty acid synthase(FAS) genes related to the induction of lipogenesis. In addition, MCPS reduced the production of adipocyte-induced pro-inflammatory cytokines. Conclusions : MCPS could regulate the accumulation of lipids and expression of adipogenic genes via inhibition of transcript factors related to induction of adipose differentiation.

This study was done to investigate the effect of vitamin C on hepatic biliary and microsomal function during ischemia and reperfusion. Rats were treated with vitamin C(20, 100, 400, 1600 mg/kg) or with vehicle(saline) and then subjected to 60 min no-flow hepatic ischemia in vivo. Control animals were time-matched sham ischemic animals. After 1 or 5 hr of reperfusion, bile was collected, blood was obtained from the abdominal aorta, and liver microsomes were isolated. In vehicle-treated ischemic rats, serum ALT and AST levels peaked at 5 hr and were significantly attenuated by vitamin C 20 mg/kg and 100 mg/kg treatment. Similarly, hepatic wet weight-to-dry weight ratio was decreased in the vehicle-treated ischemic group. Vitamin C 20 mg/kg and 100 mg/kg treatment minimized the increase in this ratio. Lipid peroxidation was elevated in vehicle-treated ischemic group, but this elevation was also inhibited by vitamin C 20 mg/kg and 100 mg/kg treatment. Bile flow and cholate output, but not bilirubin output, were markedly decreased by ischemia/reperfuzion. Vitamin C 20 mg/kg and 100mg/kg treatment restored the secretion but vitamin C 1600 mg/kg reduced the cholate output. Cytochrome P-450 content was decreased by ischemia/reperfusion and restored by vitamin C 20 mg/kg and 100 mg/kg treatment to the level of sham operated group but decreased by vitamin C 1600 mg/kg. Aminopyrine N-demethylase activity was decreased and aniline p-hydroxylase activity was increased by ischemia/reperfusion. The changes in the activities of aminopyrine were prevented by vitamin C 20 mg/kg and 100 mg/kg treatment, but not by 400 mg/kg and 1600 mg/kg treatment. Our findings suggest that ischemia/reperfusion diminishes hepatic secretory functions as well as microsomal drug metabolizing systems, small doses(20, 100 mg/kg) of vitamin C significantly ameliorates and large doses(400, 1600 mg/kg) of vitamin C aggravated these ischemia/reperfusion-induced changes.

To investigate the beneficial effects of fiber derived from agar on the lipid and glucose metabolism of obese model mice, changes in the fat accumulation, lipid content, and insulin concentration were measured in C57BL/6N mice fed a high-fat diet (HFD) and treated with a beverage containing agar (BCA) for 9 weeks. The feed efficiency ratio was significantly decreased in the HFD+BCA treatment group, although the body weight and food intake were maintained a constant level. Also, the fat accumulation in the fatty tissue and liver were lower in the HFD+BCA treatment group than in the HFD+Vehicle treatment group. Furthermore, a significant decrease was detected in the levels of total cholesterol (TC) and LDL after the BCA treatment, while a constant HDL level was maintained in the same group. Moreover, the serum insulin concentration was significantly decreased in the HFD+BCALo (Low concentration) and HFD+BCAMi (Middle concentration) groups compared to the HFD+Vehicle group. Therefore, the results suggest that the long-term administration of dietary fiber from agar can improve fat accumulation in the fatty tissue and liver, the serum lipid profile, and the insulin concentration in the blood. Also, the results provide evidence that the inclusion of agar fiber in beverages results in significant hypolipidemic and hypoinsulinemic effects.

This study was done to investigate the effects of ethanol extract of Cassia semen (Cassia tora L.) on the activities of hepatic oxygen free radicals metabolizing enzymes and blood lipid profile in rats of hepatotoxicity induced by ethanol. Sprague-Dawley male rats weighing 100~160 g were divides into 5 groups; control grouts (CON), Cassia semen ethanol extracts (200 mg/kg) treated group (CEL), ethanol (10 mL/kg, 35%) treated group (ETH), Cassia semen ethanol extracts (200 mg/kg) and ethanol treated group (CE1 ) and Cassia semen ethanol extracts (400 mg/kg ) and ethanol treated group (CE2), respectively. Compared with ETH, the growth rate of CE1 and CE2 were to be increased tendency, and in blood levels of total cholesterol, LDL-cholesterol and the activities of alanine aminotranferase and asparate aminotranferase elevated by ethanol were significantly decreased (p<0.05). It was observed that the activities of superoxide dismutase, catalase, xanthine oxidase and glutathione peroxidase of rat liver increased by ethanol, were more decreased by the treatment of Cassia semen ethanol extract than the only ethanol-treated group. The content of glutathione depleted by ethanol treatment was increased in CE1 and CE2. TBA-reactants of liver increased by ethanol were decreased in CE1 and CE2, compared with ethanol-treated group. These results suggested that ethanol extract of Cassia semen may influence upon the ability of oxygen free radical detoxication and lowering of blood lipid level on ethanol-induced hepatotoxicity in rat.

This study was conducted to investigate the effect of dietary protein and fiber levels on the activities of ethanol metabolizing enzymes of liver in ethanol-treated rats. Sprague-Dawley male rats were fed on diets containing two levels of protein(7, 20%/kg diet) and pectin(5, 10%/kg diet). In ethanol experiments, ethanol(25% v/v) was administered by oral intubation(5g/kg body weight) at the same time once a day Control animals received an isocaloric dose of sucrose. The rats were sacrificed after 5 weeks of feeding periods. Alcohol dehydrogenase and microsomal ethanol oxidizing system activities of hepatic tissue were increased more in ethanol-treated groups than in control groups. Increment of activities predominated in normal protein normal fiber group. Aldehyde dehydrogenase activity was decreased in ethanol-treated groups and significantly decreased in normal Protein normal fiber group. Cytochrome P-450 content was significantly increased in ethanol-treated groups and Predominated in normal protein groups. Xanthine oxidase activity was increased in ethanol-treated groups, but not significantly except normal protein normal fiber group. Glutathione content tended to increase in proportion to level of dietary protein and was higher in normal fiber groups than in high fiber groups, whereas it was decreased by ethanol treatment. Lipid Peroxide content was significantly increased in low Protein normal fiber groups.

This study was carried out to investigate the Ca and Mg supplementation on the serum and liver lipid parameters in ovariectomized and Ca deficiency rats. Total 50 Sprague Dawley female rats (6 weeks) were divided into 5 groups and bred for 12 weeks: sham operated control group (SNCa), OVX Ca deficiency poop (OLCa) with Ca deficiency diet (0.1% Ca modified AIN-93N diet), OVX Ca deficiency & Mg supplement group (OLCaMg), OVX adequate Ca group (OACa; 0.5% Ca AIN-93N diet) and OVX adequate Ca & Mg supplement group (OACaMg). There were no significant difference among the five groups in serum total cholesterol, triglyceride and HDL-cholesterol levels. LDL-cholesterol of OVX groups was significantly higher than that of SNCa group (p < 0.01). AI (Atherogenic index), TPH (Total cholesterol/HDL-C) and LPH (LDL-C/HDL-C) of OACa group were significantly lower than those of OLCa groups. OACaMg group had significantly lower levels LDL, AI and TPH than OLCa group. There was no significant difference in lever cholesterol level. However, liver total fat content of OACa was significantly lower than that of OLCa. From the above the results, it is concluded that the accumulation level of calcium shows how the supplement of magnesium affects hyperlipidemia. Therefore, in order to prevent women#s hyperlipidemia after menopause, and to keep healthy, it is encourage able to consider how the supplement of magnesium relates calcium intake.

Monascus-fermented Korean red ginseng (MFRG), fermented by Monascus purpureus KCCM 12002, may be an ideal candidate for the hepatoprotectic, hypolipidemic and antioxidative activities. Effect of MFRG powder on these parameters in rats was investigated. Body weight gain, food intake, and water consumption were not significantly different among the groups. Total and relative weights of liver were significantly higher in MFRG group than that in other groups. The activities of AST and $\gamma$-GTP were highly lowered in MFRG group compared to control group. Contents of serum total lipid and triglyceride were significantly lowered in silymarin group and were significantly increased in MFRG group compared to control group, but tended to be lowered in RG group. Serum content of total cholesterol tended to be lowered in silymarin, RG, and MFRG groups compared to control group. HDL-cholesterol contents was only significantly increased in MFRG group compared to control group. At the same time, atherogenic index (AI) was also significantly lowered in silymarin, RG and MFRG groups compared to control group, and this effect was more pronounced in MFRG group. Content of thiobarbituric acid reactive substances (TBARS) in the liver was significantly lowered in MFRG group and tended to lowered in silymarin and RG groups compared to control group. The hepatic glutathione concentration was significantly higher in silymarin and MFRG groups. Hepatic morphology in all experimental groups revealed clear-cut hepatic lobules with the uniform pattern of the polyhedral hepatocytes radiating towards the periphery from the central vein. These results suggested that MFRG may have anti-atherogenic index (AI) and antioxidative activity in normal dietary feeding rats.

The present study was conducted to investigate the effect of dietary grape pomace on lipid metabolism and hepatic morphology of rats fed a high fat diet. The high fat diet contained additional 15% lard to AIN 93-based diet. Male Sprague-Dawley rats were fed experimental diets containing 5% grape pomace for 4 weeks. Serum activities of glutamic-oxaloacetic transaminase (GOT) and glutamic-pyruvic transaminase (GPT) were not changed by high fat and grape pomace feeding. Serum concentration of triglyceride in rats fed a high fat diet was decreased significantly by dietary grape pomace. Hepatic concentrations of total lipid, total cholesterol and triglyceride were reduced in grape pomace groups with a high fat diet. Fecal concentrations of total cholesterol and triglyceride were increased in grape pomace groups with a high fat diet. The fecal content of coprostanol was not different among the groups. Dietary grape pomace increased the fecal excretion of cholesterol and coprostanone in rats fed a high fat diet. The fecal excretion of bile acid was not affected by feeding grape pomace in rats fed a high fat diet. Light micrographs of liver tissue revealed lipid droplets were increased by a high fat diet, but dietary supplementation of grape pomace tended to alleviate such changes.

A recipe for diet kimchi containing 20% of sea tangle to Korean cabbage kimchi (SK) was developed for weight reduction purpose. The fermentation process of SK showed typical Lactobacillus sp. growth pattern like other kimchis. The effects of SK on weight reduction was studied in high fat diet (HFD) fed rats (n=40). Diet groups used for the animal study were HFD, HFD supplemented either with Korean cabbage kimchi used as experimental control (HCK), or with SK (HSK), or with J-kimchi (JK) which was purchased at market (FJK). The effect of kimchi on preventing obesity in rat fed HFD was found to be obvious by means of reducing visceral fat contents and improving serum lipid profiles through enhancing the lipid excretion in the feces (p<0.05). Leptin concentration of rat was significantly decreased by kimchi consumption (p<0.05). This result can be interpreted that adipocytes in these animals were fewer than that of HFD group. The plasma bililubin concentration was lower in kimchi group than HFD, meaning that returning bile from ileum to the liver was reduced. When the observe beneficial effects of kimchi on preventing obesity were compared among kimchi groups, SK only reduced the relative visceral fat contents significantly than other kimchi groups (p<0.05). Besides this, other parameters such as plasma lipid profiles, feces lipids, leptin, and bililubin concentration were not significantly different, even though the most beneficial effect on these parameters was observed from SK. In conclusion, long term consumption of SK seems to have a beneficial effect on the prevention of obesity through enhancing the excretion of lipids in the feces. The dietary fiber content of SK was increased by 7% compared to CK when 20% of sea tangle was added.
