硒对新城疫免疫雏鸡红细胞免疫功能的影响

Effects of Selenium of RBC immune function in ND-immunized chicken

采用鸡红细胞免疫复合物 RBC- IC花环、鸡红细胞受体 (RBC- CR1 )花环及 RBC- CR1花环促进试验 ,通过饮水给硒的方式 ,探讨硒对新城疫免疫雏鸡红细胞免疫粘附功能及其免疫粘附促进因子活性的影响。试验结果表明 :各组平均血清硒含量变化与给硒剂量一致 ;各试验组红细胞免疫粘附功能及其血清中的免疫粘附促进因子的活性均较对照组为高。

With RBC-CR1 rosette, RBC-IC rosette and RBC-CR1 rosette assay, we studied the effect of Se on RBC immune adherence function and activity of RBC immune adherence promoting factor in ND-immunized chicken by drinking. The experimental results showed that the average content of serum Se in correspondence with Se dosage in every groups, and RBC immune adherence function and the activity of RBC immune adherence promoting factor in group 1～4, especially in group 3 were higher than in group 5.
