Abstract:
Objective: To investigate the therapeutic effect of oat β-glucans on serum lipid levels of rats with experimental hyperlipemia. Methods: Rats were fed on high fat forage for 3 weeks to establish hyperlipemia models, then the model rats were orally given oat β-glucans at doses of 133, 266 and 533 mg/(kg · d) separately. At the same time, there were 3 control groups including chitosan ligosaccharide[200 mg/(kg · d)], normal, and high blood lipid (model rats fed with distilled water). Serum levels of total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were assayed in rats of all groups and the results were compared. Results: β-glucans obviously decreased the levels of TC and LDL-C and increased HDL-C in rat hyperlipemia models. The reduction of serum lipid level in 4-week β-glucans treatment rats was more obvious than that in 3-week β-glucans treatment rats. Besides, β-glucans showed an obvious dosage dependent effect in reducing serum lipid level without adverse effect. Oat β-glucans had a better lipid-reducing effect than ligosaccharide did. Conclusion: Oat β-glucans can obviously decrease serum lipid in rats with hyperlipemia.
