摘　　要：拟研究左旋咪唑、聚乙烯亚胺和聚肌胞分别配合灭活H5N1禽流感病毒口服免疫雏鸡,空肠、回肠中IgA和IgG抗体分泌细胞数量和分布的变化。应用左旋咪唑、聚乙烯亚胺和聚肌胞分别配合灭活H5N1禽流感病毒经口免疫雏鸡后,通过免疫组织化学方法显示空肠、回肠IgA和IgG分泌细胞。聚乙烯亚胺配合灭活禽流感病毒口服免疫后,空肠、回肠IgA和IgG分泌细胞的数量均显著(P<0.05)高于单独口服灭活禽流感病毒免疫后的数量;左旋咪唑和聚肌胞分别配合灭活禽流感病毒口服免疫后,空肠、回肠IgA分泌细胞数量显著(P<0.05)增加,IgG分泌细胞数量无明显变化。研究表明,左旋咪唑、聚肌胞和聚乙烯亚胺分别配合灭活禽流感病毒口服免疫雏鸡,均能提高肠道局部体液免疫水平,聚乙烯亚胺的效果最好,价格更便宜。The experiment was conducted to investigate the effect of oral immunization with H5N1 inactivated avian influenza virus（IAIV）and adjuvant levamisole hydrochloride（LMS）,Poly（I：C）,Polyethyleneimine（PEI）respectively on the number and distribution of antibody secreting cells in chicken jejunum and ileum.Chicken were immunized through the oral route with H5N1 IAIV and adjuvants LMS,Poly（I：C）and PEI respectively,IgA and IgG secreting cells were detected by Immunohistochemistry to evaluate the immune effect.The number of IgA and IgG secreting cells in jejunum and ileum induced by PEI plus H5N1 IAIV were substantially（P〈0.05）greater than antigen-alone treatment.The number of IgA secreting cells in jejunum and ileum induced by LMS and Poly（I：C）plus H5N1 IAIV were substantially（P〈0.05）increased than antigen-alone treatment,the number of IgG secreting cells have no changes.Our study showed that chicken oral immunization with H5N1 IAIV and adjuvant LMS,Poly（I：C）and PEI respectively strengthen intestinal humoral immune level in intestine,but the cost of PEI was cheapest and most effective oral immune adjuvant.
