  • The effects of water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower on serum lipid concentrations were evaluated in rats. Forty-eight male Sprague-Dawley rats weighing l00±l0 g were divided into six groups and fed high fat diets for six weeks. Experimental groups were administered with following diets; Control diet, animal, plant high fat diet and control and high fat diets with 2% water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower. Tissue weights of liver, lung, stomach, heart, kidney and spleen of high fat diet exposed rats were reduced by water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups. The concentrations of serum triglyceride in rats fed the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower were lower than those in other groups. The concentrations of total cholesterol in water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower group were lower than those in high fat diet groups. The concentrations of HDL-cholesterol in serum of the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups were significantly higher than those of other groups. The levels of LDL-cholesterol in serum of the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups were tended to be lower than those of other groups. GPT and GOT activities were decreased in water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups and than in the high fat group. LDH activity was lower in the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups than in the high fat group. These results suggest that water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups may reduce elevated levels of serum lipid concentrations in rats fed high fat diets.

  • Baek-kimchi (whitish baechu kimchi) was evaluated for anti-obesity properties and effects on triglyceride (TG) and cholesterol in blood and adipose tissues in rats fed a high fat (20 %) diet, and compared to the similar effects of baechu kimchi. Baek-kimchi does not use red pepper powder but contains higher levels of sliced radish and pear than baechu kimchi. SD rats were raised for four weeks on either a normal diet (ND, based on the AIN-93M diet), high fat diet (HFD, supplemented with 16% lard oil in the ND), or HFD containing 5 % baek-kimchi or 5 % baechu kimchi. Feed consumption was not different among the groups, but weight gains were significantly lower in the groups fed either the normal diet or HFD with baek-kimchi or baechu kimchi diets than the group fed HFD alone. The weights of liver and epididymal and perirenal fat pads in baek-kimchi and baechu kimchi diet groups were lower than those of the HFD groups, but the baek-kimchi diet group had lower epididymal and perirenal fat pad weights than the baechu kimchi diet group (p<0.05). The baechu kimchi dietary group also had significantly lower triglyceride and cholesterol contents in liver and epididymal and perirenal fat, reversing the higher levels seen in HFD. Baek-kimchi and baechu kimchi diets were also effective in lowering serum triglyceride and cholesterol levels (p<0.05). These results suggest that baek-kimchi and baechu kimchi consumption can reverse the effects of HFD on weight gain and blood and tissue lipids, and that baek-kimchi is more effective than baechu kimchi. The greater effect is probably due to the higher content of radish and pear used in baek-kimchi.

  • A preliminary diet experiment utilizing Jerusalem artichoke's inulin, lotus leaf powder, nettle powder and eucalyptus powder extract indicated that combining all four elements gave the most effective result. Therefore, a study was conducted to evaluate the effectiveness of combined diet for weight loss. In this study, Sprague-Dawley, male white rats about 200 g in weight was fed with high fat diet for 8 weeks in order to induce obesity followed by 4 week administration of combined diet to look into the effect of the diet. After a total of 12 weeks of feeding, factors relevant to weight, blood, and lipid metabolism by liver in the body were researched and histologic change was examined with optical microscope. In terms of weight change, both high fat diet group and regular diet group gained weight from high fat diet for 8 weeks compared to normal group. Then, for another 4 weeks, while normal group and high fat diet group kept gaining weight, combined diet group which was provided with high fat diet for 8 weeks, lost weight to the normal group level after 3 week administration of diet. However, after the 4th week of administration, the group weighted significantly less than the normal group and the efficiency of diet also significantly dropped. In the biochemical analysis of blood, total cholesterol, LDL-cholesterol, triglyceride, glucose, GOT, GPT, ${\gamma}-GTP$ and creatine showed significant increase in high fat diet group and there was no significant difference between diet group and normal group except for GPT, ${\gamma}-GTP$ and creatine. In the biochemical analysis of liver, there was significant increase in LDL-cholesterol, triglyceride of high fat diet group compared to normal group, while there was no significant difference in term of total cholesterol and HDL-cholesterol. Compared to normal group, diet group had higher HDL-cholesterol, while total cholesterol dropped significantly. There was no significant difference in terms of LDL-cholesterol and triglyceride. Besides, in high fat diet group, observation of histologic change in liver and change in ultrastructure showed volume increase of hepatic cell and severe fatty degeneration in hepatic cell around hepatic vein. However in diet group, like normal group, no pathological change was observed in terms of cytoplasm, nucleus and capillary in hepatocyte and the alignment of hepatocyte had regularity thanks to the administration of combined diet. Therefore, combined diet utilizing Jerusalem artichoke's inulin, lotus leaf powder, nettle powder and eucalyptus powder was proven to be an effective measure to prevent and improve obesity as a result of abnormal adipose deposition.

  • This study was conducted to investigate the cholesterol lowering and anti-obesity effects of an ethanol extract of broccoli sprouts (BS) in rats fed high fat diet. Male Sprague-Dawley rats weighing $150{\sim}155g$, were divided into 6 groups; a normal diet group (ND), a high fat diet group (HFD), a normal diet and BS with 200 mg/kg treated group (ND-BSL), a normal diet and BS with 400 mg/kg treated group (ND-BSH), a high fat diet and BS with 200 mg/kg treated group (HFD-BSL), and a high fat diet and BS with 400 mg/kg treated group (HFD-BSH). The body weight gain and mesenteric adipose tissue weight were increased by high fat diet, but gradually decreased to the corresponding level of ND group after administration of BS extract. The liver and epididymal adipose tissue weights of HFD group were the highest among the six groups, although the difference was not significant. Food intake was lower in high fat diet groups compared with normal diet groups. The serum ALT and AST activities that were elevated by the high fat diet were significantly decreased after BS administration. Levels of serum total cholesterol, LDL-cholesterol, triglyceride and the atherogenic index tended to be decrease in the BS administered groups compared with HFD group. However, HDL-cholesterol level in serum decreased in HFD group and markedly increased in BS administered groups. There were no differences in the contents of serum triglyceride, LDL-cholesterol and HDL-cholesterol between normal diet groups. Levels of total cholesterol and triglyceride in liver and adipose tissues were also lower in BS administrated groups than in HFD group. The activities of heparin-releasable lipoprotein lipase (HR-LPL) and total-extractable LPL (TE-LPL) in adipose tissue were increased in HFD group compared with the BS administered groups, but those of the ND-BSL group and ND-BSH group were similar to ND group. These results suggest that BS ethanol extract may exert cholesterol-lowering effect and potentially reduce lipid storage.

  • In this study, we investigated the effects of silybin on body weight and glucose tolerance in mice fed high fat diet mice. We found that body weight, plasma TG contents, fat size, glycerol, 3-hydroxybutyrate and total cholesterol were significantly decreased in silybin (500 mg/kg) supplemented groups compared to high fat diet group. Whereas, total food intake was not changed between high fat diet group and high fat diet plus silybin group. Futhermore, supplement of high fat elevated the glucose intolerance and was improved in silybin supplement group. Finally, we examined the effect of silybin on circulating adipocytokine level to explore the possible mechanism by which silybin improves high fat diet-induced obesity and diabetes. The silybin supplement significantly reduced the level of adipocytokine, such as leptin, resistin, IL-6, and MCP-1 induced by high fat diet. These results suggest that silybin can be used to improve obesity and diabetes.

  • The study was performed by examining the effects of fermented liquid of Crataegi Fructus on the lipid profile improvement in rats fed high fat diets. Sprague-Dawley rats of weighting $180.0{\pm}30g$ were randomly divided into five groups : basal diet (Normal control group, NCG), only high fat diet (High fat control group, HFC), high fat diet and supplemented with 1.69 mg/100 g body weight, 3.38 mg/100 g body weight, 6.76 mg/100 g body weight by fermented liquid of Crataegi Fructus - HFL, HFM, HFH group). These experimental diets were fed for 6 weeks. The fermented liquid of Crataegi Fructus fed groups had more significantly decreased in the levels of serum total cholesterol, triglyceride, LDL-cholesterol and atherogenic index than the high fat control group, while the HDL-cholesterol was higher when compared to the normal control group. Total lipid, total cholesterol, triglyceride, LDL-cholesterol contents in liver were decreased in high fat experimental groups. But the degree of increment was reduced by administration of fermented liquid of Crataegi Fructus. while the fermented liquid of Crataegi Fructus fed group had ore significantly increased in the level of HDL-cholesterol than the high fat control group. The singularity of the unsaturated fatty acid contents attracted our attention. Especially, the polyunsaturated fatty acid compositions were 36.36%, 34.70%, 20.31%in serum, liver and fecal of fermented liquid of Crataegi Fructus fed groups, respectively. These results imply that the fermented liquid of Crataegi Fructus can be used as possible food resources and medicinal food materials.

  • This study was performed to investigate the effects of ethanolic extract of Ulmus davidiana root (UE) on lipid metabolism in mice fed a high-fat diet (HF) for 7 weeks. Forty male ICR mice were randomly divided into four groups; normal diet group (N), high-fat diet group (HF), HF with 0.5% UE (HF-L) and 1% UE (HF-H) group. Body weight, body weight gain, and liver weight in the HF group was significantly higher than in the N group, while those of the HF-L and HF-H group were unchanged. UE improved HF-induced dyslipidemia by reducing serum triglyceride, total cholesterol, and the atherogenic index. There was no difference in serum HDL-cholesterol among experimental groups. However, the HDL-cholesterol/total cholesterol ratio was significantly increased in the HF-L and HF-H group. Histological analysis showed that HF-fed mice developed hepatocellular microvesicular vacuolation as a result of fat accumulation. These changes were attenuated by 1% UE supplementation. In addition, hepatic triglyceride and cholesterol levels in the HF-H group significantly reduced. Taken together, these results demonstrated that lipid levels in the blood and liver were reduced by UE, suggesting that it might be beneficial for the prevention and treatment of hyperlipidemia and fatty liver.
