摘  要：
将由未免疫接种腔上囊病疫苗鸡的种蛋孵化而来的160只1日龄海兰白雏鸡随机分为A、B、C和D共4组。A组为对照组,B、C和D组于26日龄时按每只0.3 mL的剂量用IBDV攻毒。A、B组未用黄芪多糖(APS)处理,C、D组从攻毒当日起连续胸肌注射APS 6 d,剂量分别为每只鸡5 mg和10 mg。分别在21、29、32、35、38日龄时心脏采血1~3 mL,测定E-C3bRR、E-ICRR、ERER和ERIR。结果显示,雏鸡感染IBDV后可使E-C3bRR和ERER显著降低(P<0.01);APS处理组E-C3bRR、E-ICRR、ERER均高于A、B组(P<0.01),其中D组最高,而ERIR则与A组相似。证实,雏鸡感染IBDV后红细胞免疫功能低下,而APS可显著提高其红细胞免疫功能。

摘  要：
One hundred and sixty Haline white chickens,aged 26 days-old which were negative to the antibody to infectious bursal disease virus(IBDV),were divided randomly into four groups of A,B,C and D with 40 chickens in each group.Chickens in Group B,C and D were infected with 0.3mL of IBDV by nasal drip and eye droppings when they were 26 days-old.Chickens in Group A and B were not injected with astragalus polysaccharide(APS).Each chicken in Group C and D was injected with 5mg and 10mg of APS per day from days 26 to 31,respectively.1-3 mL blood were taken from hearts of chickens on days 21,29,32,35 and 38,respectively,and erythrocyte-C_(3b) receptor rosette rates(E-C3bRR),erythrocyte-C3b immune complex rosette rates(E-ICRR),erythrocyte rosette forming enhancing rates(ERER) and(erythrocyte) rosette forming inhibitory rates(ERIR) were examined.E-C3bRR and ERER declined significantly in the chickens infected with IBDV(P<0.01),E-C3bRR,E-ICRR and ERER in Groups C and D treated with APS were higher than that in Group A and B(P<0.01),and the ERIR in Groups C and D were similar to that in Group A.The results suggested that immunological function of chicken erythrocytes decline after infection with IBDV and APS enhances obviously the immunological functions of chicken erythrocytes.
