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 aimed to investigate the improvement effect of 5% (w/w) mung bean (Phaseolus aureus L.) on lipid composition and protein concentration in hyperlipidemic rats. Seven-week-old male (Sprague-Dawley) rats were divided into four groups (n=6, each), and fed experimental diets containing mung bean meal [basal diet+5% (w/w) mung bean (BM), basal-hyperlipidemic diet+5% (w/w) mung bean (BHM)], basal-hyperlipidemic diet (BH), and control (basal diet, BD). Lipid composition in the mung bean diet groups (BM and BHM) evidenced significant reductions in serum total cholesterol, low-density lipoprotein cholesterol, atherosclerotic index, cardiac risk factor, triglyceride, phospholipid, free cholesterol, cholesteryl ester, blood glucose, nonesterified fatty acid, and an elevation in high-density lipoprotein cholesterol. The serum albumin/globulin ratio was increased in mung bean diet-supplemented rats compared to that in hyperlipidemic rats (p < 0.05). Total calcium, phosphorus and potassium concentrations in sera were higher in the BM, BHM and BD groups than in the BH group. Concentrations of sodium and chlorine in sera were lower in the mung bean diet-supplemented groups than in the hyperlipidemic group. The in vivo experiments showed that ingestion of mung bean was effective in improving lipid composition, protein concentration, and blood glucose.

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.

Gamigwaruhaebaekwhanggum-Tang (GGHWT) have been evaluated for antihyperlipidemic effects on experimental hyperlipidemic rats and mice induced by Triton WR-1339, com oil and high cholersterol-diet. Especially, GGHWT is formulated with Trichosanthis Fructus, Pinelliae Tuber, Aurantii Immaturus Fructus, Magnoliae Cortex, Allii Macrostemi Bulbuls, Cinnamomi Ramulus and Scutellariae Radix. Oral administration of GGHWT at 500 mg/kg/day for 3 days significantly inhibited the increase of serum triglyceride and LDL-cholesterol, liver triglyceride in hyperlipidemic rats induced by Triton WR-1339. And, GGHWT significantly inhibited the increase of serum triglyceride in hyperlipidemic rats induced by corn oil. Also, administration of GGHWT (500 mg/kg, once daily for 1 week, p.o.) prevented the increase of serum total cholesterol, triglyceride, LDL-cholesterol, liver total cholesterol and triglyceride in 1% cholesterol-diet fed mice. These results suggest that GGHWT is effective for the treatment of hyperlipidemia.

This study investigated the effects of soyoligosaccharide consumption on lipid profile of plasma, liver and feces and immune responses in Sprague-Dawley male rats. Sixty male Sprague-Dawley rats 4-wk-old were provided the soyo-ligosaccharide containing diets for 4 weeks (0, 100 g/kg diet); each of these diets was supplemented with either 70 or 200 g fat/kg diet, giving a total of 4 experimental groups. The effect of weight reduction was most significantly observed in the group fed low fat and soyoligosacchairde diet. The plasma total lipid and cholesterol contents were not changed by either fat proportion or soyoligosaccharide supplementation in the diets. Also the plasma triglyceride lowering effect by soyoligosaccharide was not observed in rats fed either low fat or high fat diet. However, the significant decrease in TG contents was found with rats fed high fat diets compared to the control/no soyoligosaccharide diet. Elevation of plasma LDL-cholesterol and reduction of HDL-cholesterol by feeding high fat diet was not altered by supplementing soyoligosaccharide. This was also applied to the liver lipid profiles. The significant increases in liver total lipid, trigly-cerides and cholesterol by high fat diet was not abolished by feeding soyoligosaccharide. However, the desirable effects of feeding soyoligosaccharide were found with total lipid and cholesterol excretion through feces in rats fed high fat diets. Immune organ weights and spleen cell proliferations did not affected by experimental diets. These results de-monstrated that soyoligosaccharide intakes increased the lipid output via feces, especially in rats fed the high fat diet, but more researches are needed on immune responses.

This study was conducted to investigate the effects of caffeine on lipid and mineral content in the serum of rats given a caffeine free diet(FC), a low caffeine diet(LC), a medium caffeine diet(MC), a high caffeine diet(HC) or a super-high caffeine diet(SHC) for 5 weeks. Thirty male Sprague-Dawley rats(body weight, $110{\pm}0.3$ g) were blocked into 5 groups and fed diets with or without pure caffeine. Caffeine intake models showed a lower mean-weight gain, food intake and food efficiency in the high caffeine diet groups(MC, HC and SHC groups) than the groups receiving a caffeine free or low caffeine diet(FC and LC groups). Serum total lipid, total cholesterol and LDL-cholesterol levels decreased, but the serum HDL-cholesterol level increased according to the increase in caffeine intake. Serum total lipid, HDL-cholesterol and serum triglyceride were significantly lower in the HC and SHC groups than the FC group. All of the serum minerals decreased as caffeine intake increased. Serum iron, calcium, magnesium and phosphorus significantly decreased in the HC and SHC groups compared to the FC group. Caffeine intake was associated with less weight gain and reduced serum total cholesterol, triglyceride and total lipid. The results suggest that rats fed high amounts of caffeine may be susceptible to osteoporosis due to their low levels of calcium, magnesium and phosphorus.
