摘要: 为研究黄芪灵芝口服液对雏鸡免疫功能的影响,本试验将180只14日龄雏鸡随机分成9组并通过点眼滴鼻免疫新城疫(ND)疫苗。1~3组分别是黄芪灵芝口服液高、中和低剂量组;4~6组分别是环磷酰胺+黄芪灵芝口服液高、中和低剂量组;7~9组分别为环磷酰胺组、阳性对照组及生理盐水对照组。分别于免疫后的第7、14、21、28天测定脾脏淋巴细胞增殖和抗体滴度的动态变化。结果表明,黄芪灵芝口服液能提高雏鸡脾脏淋巴细胞的增殖能力和促进新城疫病毒(NDV)抗体的产生,能一定程度上缓解环磷酰胺的免疫抑制,其中黄芪灵芝口服液低剂量组对脾脏淋巴细胞增殖效果最好,黄芪灵芝口服液可作为一种新型的免疫增强剂。

Abstract: In order to study the effects of the oral liquid of Astragalus and Lucidum polysaccharides on immunological function in chickens,one hundred and eighty 14-day-old chickens were randomly divided into 9 groups and inoculated with the Newcastle disease vaccine.1 to 3 experimental groups were respectively the oral liquid of Astragalus and Lucidum polysaccharides high,middle and low dose groups;4 to 6 experimental groups were respectively the oral liquid of Astragalus and Lucidum polysaccharides with cyclophosphamide high,middle and low dose groups;7 to 9 experimental groups were respectively cyclophosphamide group,positive control group and saline control group.The proliferation index of spleen lymphocyte and Newcastle disease virus antibody level by HI method were determined on days 7,14,21 and 28 after vaccination.The results showed that the oral liquid of Astragalus and Lucidum polysaccharides could apparently promote lymphocyte proliferation and enhance antibody titer,and alleviate the immunosupperession of the chickens in some degree,the low dose of the oral liquid of Astragalus and Lucidum polysaccharides promoted lymphocyte proliferation best,implying that the oral liquid of Astragalus and Lucidum polysaccharides would be expected as a candidate of new-type immunopotentiator.

Key words: Astragalus and Lucidum; chicken; proliferation of spleen lymphocyte; antibody titer; immunopotentiator
