摘要：

This study was conducted to evaluate the effects of compound polysaccharides (cPS) on the immune responses via chicken models. First, in screening experiment, a comprehensive analysis for immunomodulatory activity of four cPSs, including Astragalus polysaccharides CAPS), Epimedium polysaccharides (EPS), sulfated APS (sAPS) and sulfated EPS (sEPS), was performed in vitro and in vivo. APS-sEPS was picked out having the best effect on lymphocyte proliferation and raising the antibody titers. Therefore, the adjuvanticities of APS-sEPS on Newcastle disease (ND) and avian influenza (AI) vaccine were further validated. Chickens were administrated with ND or AI vaccines containing APS-sEPS of 150, 100 and 50 mg/kg, respectively, taking oil adjuvant vaccine as control. It was observed ND or AI antibody titers and lymphocyte proliferation were enhanced at 100 mg/kg of APS-sEPS. In conclusion, appropriate dose of APS-sEPS may be a safe and efficacious immune stimulator candidate suitable for vaccines. (C) 2012 Elsevier B.V. All rights reserved.
