当归多糖对鸡红细胞免疫功能的影响

目的：观察不同浓度的当归多糖（ASP）对正常罗曼雏鸡免疫功能的影响。方法：将80只1日龄健康罗曼雏鸡随机分为4组,每组20只。分别于1日龄皮下注射生理盐水以及不同浓度的当归多糖,连续注射7 d,于7、14、21、28、35、42、49、56日龄采血,检测红细胞免疫功能。结果：试验结果表明,使用当归多糖后,各试验组红细胞-C3b花环率和红细胞-IC花环率明显升高。浓度为25 mg/mL当归多糖组红细胞C3b花环率和红细胞IC花环率显著高于其他多糖组。结论：当归多糖可提高鸡的红细胞免疫功能,其中以浓度为25 mg/mL当归多糖效果最佳。

Effects of Angelica sinensis polysaccharides on erythrocyte immune function in chickens

Object： To observe the influence of Angelica sinensis polysaccharides（ASP） on the immune function of healthy Roman chicken.Methods： Eighty one-day-old chickens were randomly divided into four groups with each group of 20 chickens.Then,group 2-4 was hypodermically injected with different concentration of ASP for seven days continuously,and blood sample was collected on the 7th,14th,21st,28th,35th,42nd,49th and 56th to evaluate the immune function of red blood cell in chickens.Results： The RBC-C3b rosette rate and RBC-IC rosette rate were all increased after the use of ASP.Chickens treated with 25 mg/mL of ASP were higher on RBC-C3b rosette rate and RBC-IC rosette rate than others.Conclusion： ASP could promote the immune function of erythrocytes in chicken with an optimal dosage of 25 mg/mL.
