【摘要】 选择健康仔鸡 4 0只 ,随机分为 4组 ,每组 10只。Ⅰ组为健康对照组 ,Ⅱ～Ⅳ组为不同处理的试验组。在 4 5日龄时 ,Ⅱ组免疫传染性喉气管炎 (ILT)疫苗 ,Ⅲ组免疫ILT疫苗同时肌肉注射中药免疫增强剂Ⅰ ,Ⅳ组免疫ILT疫苗同时肌肉注射中药免疫增强剂Ⅱ。分别在免疫前 1天、免疫后第 3天和第 9天 ,测定各组鸡的红细胞免疫功能状态。结果发现 ,试验Ⅱ组的鸡在ILT疫苗免疫后 3天 ,RBC_CR1花环率和RBC_IC花环率显著降低 ,与其他各组比较差异极显著 (P <0 .0 1)。免疫后 9天 ,RBC_CR1花环率和RBC_IC花环率升高到正常水平 ;而Ⅲ组和Ⅳ组 ,免疫后RBC_CR1花环率高于Ⅰ组 (P <0 .0 1、P <0 .0 5 )。说明ILT疫苗免疫会引机体红细胞免疫功能的短暂性降低 ;疫苗免疫的同时使用中药增强剂能够消除红细胞免疫功能短暂性降低的不良反应更多还原

【Abstract】 commercial chickens were selected and divided into 4 groups randomly,10 chickens each group.The birds were inoculated with ILT vaccines of the same dose at 45 days of age.Group Ⅰ was set as control;Group Ⅱ was inoculated with vaccine only;group Ⅲ was inoculated with vaccine and injected intramuscularly with Chinese herbal immunopotentiator Ⅰ;Group Ⅳ was done with Chinese herbal Ⅱ along with the vaccination.The immune functions of red blood cells of the birds in different groups were measured at 1 day before.and 3 days,9 days after inoculation respectively.The results indicated that the RBC_CR1 and RBC_IC rosette rates of group Ⅱ decreased at 3 days post immunization,significantly lower than the other groups (p<0.01),and returned to normal level at 9 days post vaccination.Suggested that ILT vaccine can induce transit decrease of RBC immune function.when Chinese herbal immunopotentiator Ⅰ or Ⅱ was applied,the RBC_CR1 and RBC_IC rosette rate was found to be greatly higher than other groups.The result indicated that the Chinese herbal immunopotentiator can enhance the immune function of RBC.更多还原
