  • The effect of mushroom extracts from Pleurotus ostreatus and Lentinus edodes on carbon tetrachloride(CCl4)-induced hepatotoxicity was investigated. Rats were administered orally each mushroom extract at the dose of 150mg/kg, foolwed by treatment with CCl4. Liver damage was produced in male Sprague-Dawley rats, after 21hrs from dosing with CCl4(0.25ml/kg) which were given intraperitoneally. Liver damage without renal injury was confirmed by measuring plasma enzyme, creatinine and blood analysis and liver analysis. Plasma aminotransferase activity, and levels of cholesterol and triglyceride were analyzed. Plasma alanine aminotransferase and aspartate aminotransferase activities were decreased by 34% and 61.5% in pretreatment group of Lentinus edodes compared with CCl4 treated group, respectively. The adminstration of all mushroom extracts led the plasma cholesterol and triglyceride levels decrease more than the CCl4-treated rats. These results suggest that Lentinus edodes extract protect liver from damage induced by CCl4.

  • The study examined the effects of dietary green tea powder supplementation on blood glucose, and plasma and liver lipid concentrations in diabetic rats. Twenty-five male Sprague-Dawley rats (body weight $200{\pm}5\;g$) were divided into two groups (diabetic and non-diabetic), which were each randomly divided into two subgroups that were fed a control and 1% green tea powder-supplemented diet. Serum and liver lipid concentrations were measured by established techniques. Low density lipoprotein-cholesterol (LDL-C) was calculated from an established equation. Body weight gain and feed efficiency ratio were lower in diabetic rats than in non-diabetic rats regardless of diet. There were no differences in weight gain in diabetic and non-diabetic rats consuming the control and green tea powder-supplemented diets. The levels of fasting plasma glucose, serum total cholesterol, triglyceride, LDL-C and atherogenic index of diabetic rats were significantly higher than that of non-diabetic rats. Conversely, the levels of high density lipoprotein-cholesterol (HDL-C) of diabetic rats was significantly lower than that of non-diabetic rats. Fasting plasma glucose, serum total cholesterol, triglyceride, LDL-C and atherogenic index were significantly lower in diabetic rats fed the green tea powder diet than in rats fed the control diet, and HDL-C was significantly higher in rats fed the green tea powder diet than in rats fed the control diet. The content of liver total cholesterol and triglyceride of diabetic rats were significantly higher than that of non-diabetic rats. Liver total cholesterol and triglyceride were significantly lower in diabetic rats fed green tea powder-supplemented diet than in rats fed the control diet. It is concluded that green tea powder supplementation positively influences blood glucose and lipid metabolism in diabetic rats. The present study, although not directly applicable to humans, may have some implications for individuals who habitually consume green tea powder.

  • The effects of taurine on plasma and liver cholesterol, erythrocyte ouabain sensitive Na efflux and platelet aggregation were examined in Sprague Dawley rats fed control or 0.5% cholesterol with 0.2% cholate diet. Plasma and liver levels of total cholesterol were increased significantly (p<0.05) in rats fed cholesterol diet compared to the control, and taurine significantly decreased the elevated plasma level of cholesterol in rats fed cholesterol diet (p<0.05). HDL-cholesterol was decreased in groups fed the cholesterol diet regardless of taurine supplementation and the difference between groups with and without cholesterol was significant (p<0.01). Plasma triglyceride was decreased and liver triglyceride was increased both significantly (p<0.05) in rats fed cholesterol compared to the control. Plasma and liver triglyceride in rats fed taurine was decreased significantly compared to the control (p<0.05). Intracellular Na tended to be lower in rats fed cholesterol or taurine and higher in rats fed cholesterol plus taurine compared to the control. Na efflux through Na-K ATPase and the passive leak of Na was somewhat reduced in rats fed cholesterol or taurine and was augmented in rats fed cholesterol plus taurine compared to the control, which showed a similar trend to the intracellular Na. Taurine supplementation caused a suppression of Na efflux in groups fed control diet and restored the suppressed Na efflux in groups fed cholesterol. Platelet aggregation was significantly decreased in the group fed taurine compared to the control (p<0.05) and the group fed cholesterol plus taurine was also a little lower in aggregation than the group fed cholesterol. Microscopic examination showed that taurine prevented fatty liver in rats fed cholesterol diet. Taurine known for stimulating Na-K ATPase in some cell types rather decreased erythrocyte ouabain sensitive Na-K ATPase in the present study. Taurine had hypolipidemic and hypocholesterolemic effects and inhibited platelet aggregation which may be favorable for prevention of cardiovascular diseases.

  • This study was performed to investigate the effect of dietary crab shell powder on lipid metabolism in diet induced hyperlippidemic rats. Sixteen male Sprague-Dawley rats were divided into two groups and fed 20% (w/w) carb shell powder supplemented diet for 4 weeks. Energy intake and weight gain were lower in experimental group than in control group. Concentrations of plasma triglyceride, total cholesterol, LDL-cholesterol, and atherogenic index (AI) were decreased and concentration of HDL-cholesterol was increased by crab shell powder supplementation. Concentrations of liver total cholesterol and triglyceride were significantly lower in experimental group. The crab shell decreased triglyceride and cholesterol concentration in plasma and liver, and increased bile acid excretion in feces. Therefore, the crab shell powder is assumed to exhibit function of chitin or chitosan that effects on lipid metabolism and cholesterol reabsorption.

  • Thirty Holstein calves were used to determine effects of age, environment and sex on blood metabolite concentrations during 1 to 90 d of age. Calves were weaned at 75 d of age. Environmental effects are grouped by the difference in month at birth and site of feeding. Blood samples were obtained every 2 or 3 d. The mean metabolite concentration every 3 d was used for the statistical analysis. Dairy bodyweight gain was not affected by environmental group and sex effect. Concentrations of plasma glucose, nonesterified fatty acids (NEFA), triglyceride, total cholesterol and total ketone changed with growth. These developmental changes in metabolite levels would be caused by ruminal maturation with increment of grain intake. Levels of plasma urea nitrogen, glucose, NEFA, triglyceride and total cholesterol drastically changed during a few weeks after birth, indicating that the physiological state in calves greatly changed during that time. Effects of the environmental group and sex were significant in almost all metabolites. Temperature influenced plasma metabolite concentrations. The plasma metabolite concentrations were affected more intensely by heat stress in the infant period than in the neonatal period.
