Effects of the addition of \beta-glucanase to barley-based layer diets were examined by feeding 200 Leghorn layers with corn-based (Control) and \beta-glucanase supplemented diets (Barley+ Enzyme). The results obtained are sumrrarized as follows. 1. There were no siginificant (P>0.05) differences in hen-day egg production(%) and average egg weight between two treatments, indicating that the \beta-glucanase supplemented barley could successfully replace the commonly used corn in the layer diets. 2. Although there was no statistical difference (P>0.05) between two treatments, the daily feed consumption was numerically high in layers fed the barly diet compared to the corn-based diet. 3. Availabilities of crude fat and crude fiber of the barley diet were significantly poor (P<0.05) as compared to corn diet. 4. The \beta-glucarase supplementation depressed the viscosity of barley diets and excreta from therm. 5. Both serum and egg yolk cholesterol were not significantly affected by the addition of \beta-glucarase in the barley based diet. Our data indicate that the barley grain supplemented with \beta-glucarase can be sucessfully used as an energy source of layer diet when there is a price advantage. Although some possibilities to produce low cholesterol egg were recognized in this study, further studies pertaining to long-term feeding experiment and elucidaton of the metabolic interrelationship between serum and yolk cholesterol, are required to confirm the result.

This study was performed to examine the effects of onion powder supplementation on lipid metabolism in male SD rats fed a high fat and high cholesterol diet. Experimental groups were control (C), high fat fed group (HF), high fat+onion powder intake (OP), high fat+quercetin intake (Q). The HF diet contained 1% cholesterol, 4% lard, 0.3% Na-taurocholate, and quercetin supplementation level was 0.1 g/kg diet. The OP group showed lower body weight gains compared to the control, while there was no significant difference in food efficiency ratio efficiency. When the proportion of fecal bile acids per total lipids was calculated, there was a significant decrease in the HF group compared to the control group, while the levels of the control group was same as that of the OP group. There was no significant difference between the HF and Q groups in bile acid/total lipid in feces. The amount of total cholesterol in liver increased significantly in HF group compared to the control group, while total cholesterol decreased significantly in the OP group compared to the HF group. There was a significant decrease in GOT (glutamic oxaloacetic transaminase) activity in OP and Q groups compared to the HF group. In conclusion, feeding onion powder to hyperlipidemic rates appeared to control weight gain, significantly lower the level of total cholesterol in the liver, and recover GOT activity. We also demonstrated that onion powder intake was more effective than quercetin intake.

In this study, ethanolic extracts from Hericium erinaceum cultivated with Artemisia capillaris (HEAC) were assessed for their ability to lower the cholesterol levels of male Sprague-Dawley rats fed a high-fat diet. Rats were randomly subdivided into seven test groups. Each group contained eight rats fed a high-fat diet during a growth period lasting 4 wk. Supplementation with the extracts was performed once a day for 2 wk after the high-fat diet. The control group (rats fed a high-fat diet) showed a high efficiency ratio (feed efficiency ratio) value compared to the normal group. Biochemical parameters, including total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-c), and triglyceride (TG) levels dramatically increased in the control group compared to the normal group. High-density lipoprotein-cholesterol (HDL-c) content in the control group was also significantly lower relative to the normal group. Two positive control groups, treated with simvastatin and atorvastatin, had lowered TC, LDL-c, and TG levels, and increased HDL-c content compared to the control group. Treatment with the tested extracts, including HEAC, ethanolic extracts from Hericium erinaceum, and ethanolic extracts from Artemisia capillaris reduced TC, LDL-c, and TG levels and elevated HDL-c content in the hyperlipidemia rats. The atherogenic index and cardiac risk factor values for the HEAC-treated group were 0.95 and 1.95, respectively. Simvastatin- and atorvastatin-treated groups showed atherogenic index values of 1.56 and 1.69, respectively, and cardiac risk factor values of 2.56 and 2.69, respectively. These results show HEAC possesses an ability to cure hyperlipidemia in rats and may serve as an effective natural medicine for treating hyperlipidemia in humans.

This study was intended to examine whether dehydroepiandrosterone (DHEA) and dietary fat level or source could modulate glutathione utilizing detoxifying system activity and the cytosolic NADPH generation in rat liver. Male Sprague-Dawley rats were fed semipurifed diet containing either 2%(w/w) corn oil (low level of corn oil diet: 5 ca% of fat) 15% corn oil (high level of corn oil diet: 31 cal% of fat) or 13% sardine oil plus 2% corn oil(high level of fish oil diet: 31 cal% of fat) for 9 weeks. Half of the rats in each diet group were fed a diet supplemented with 0.2% DHEA (w/w). DHEA administration increased plasma total cholesterol level in low corn oil diet-fed rats. The high fish oil diet significantly decreased plasma total cholesterol level compared to the high corn oil diet. Plasma triglyceride level was not significantly changed by DHEA administration and dietary fat level and source. Fasting plasma glucose level was increased by DHEA administration and fish oil diet. Glucose 6-phosphate dehydrogenase activity in liver tissue was significantly increased by DHEA administration and high fat diet, especially fish oil diet. Malic enzyme activity in liver tissue was significantly increased by DHEA administration and high fat diet, especially fish oil diet. Malic enzyme activity in liver tissue was significantly increased by DHEA administration. DHEA suppressed the glutathione peroxidase, glutathione-dependent enzymes compared to the low corn oil diet, while fish oil diet elevated the activity of glutathione peroxidase and glutathione reductase compared to corn oil diet. These results suggest that DHEA administration and high level of corn oil diet may suppress the cellular detoxifying system activity through reduction of glutathione utilization, while the fish oil diet did not show these effects.

This study evaluated the effect of Allium hookeri roots on lipid metabolism of the serum, liver, and adipose tissues induced by a high-fat diet in male Sprague-Dawley rats. The rats were divided into four groups with 8 rats per group for 4 weeks: the normal-diet group (N), the high-fat diet (HFD) group, the HFD containing 3% Allium hookeri (HFD-A3) group, and the HFD containing 5% Allium hookeri (HFD-A5) group. The results showed that the body weight gain and food intake of rats in the HFC-A3 and HFC-A5 groups were significantly decreased compared with those in the HFD group. The epididymal adipose tissue weight in the HFD-A5 group was significantly decreased compared with those in the HFD group, and adipose tissue weights of liver and mesenteric adipose tissues in the HFD-A3 and HFD-A5 groups were significantly decreased compared with those in the HFD group. Serum triglyceride, total cholesterol and LDL cholesterol concentrations, atherogenic index, and cardiac risk factor were significantly lower in the HFD-A3 and HFD-A5 groups than in the HFD group. Serum lipid profiles, as well as ALT and AST activities did not show any difference in all groups. Serum ALP and LDH activities were suppressed in the HFD-A5 group compared with those in the HFD group. The hepatic triglyceride and total cholesterol levels of rats in the HFD-A5 group was significantly lower than those in the HFD group. Moreover, triglyceride and total cholesterol in the epididymal and mesenteric adipose tissues were significantly lower in the HFD-A5 group than in the HFD group. These results demonstrated that the intake of Allium hookeri showed a hypolipidemic effect, changing the lipid metabolsim of a high-fat diet induced rats.
