摘要:   目的: 探讨细胞因子在旋毛虫感染免疫中的调节作用。方法: 采用间接ELISA 和生殖力指数测定等方法对IL-2 作用下感染旋毛虫小鼠的IgG抗体水平及寄生虫感染力进行连续观察。结果: 不同剂量IL-2对不同地理株感染小鼠产生的影响存在较大差异: 对于黑龙江株猪型旋毛虫感染小鼠, IL-2 注射具有明显抗虫效果; 而对于美国株猪型旋毛虫感染的小鼠, IL-2 对成虫繁殖力无显著影响, 但大剂量IL-2 (每鼠2 000 U/次) 使新生幼虫的感染力降低。结论: IL-2 对黑龙江株猪型旋毛虫感染力有明显抑制作用。

Abstract:  AIM: To study the immunoregulation of IL-2 in Trichinella-infected mice. METHODS: Mice infected respectively with HL strain and AM strain larvae of Trichinella spiralis were treated ip with IL-2 from the second day postinfection for 3 days. Serum IgG antibody levels were determined by ELISA and the infection capacity was determined using reproductive capacity index (RCI). RESULTS: In HL, higher dosage of IL-2 injection induced lower RCI and showed apparent anti-Trichinella effect. In AM, both low and high dose of IL-2 had no measurable effect on RCI, however, high dose of IL-2 reduced the infectivity of newborn larvae. CONCLUSION: IL-2 exhibits apparent suppressive effect on the infectivity of T.spiralis of HL strain.\;
