OBJECTIVE: To evaluate the effects of genetically modified maize with Cry1Ab and epsps genes on immune function in F3 rats.
METHODS: A total of 180 weaning SD rats for F0 generation were randomly divided into three groups, which were treated with AIN-93 G feed control diet, parental maize diet and genetically modified maize diet respectively. After three generations of breeding, antibody producing cells determination, concanavalin A(ConA)-induced lymphocyte transformation test, natural killer(NK)cells activities assay, whole blood lymphocyte subtype detection, delayed type hypersensitivity test and immunity organ index were performed.
RESULTS: There were no significant differences between parental maize diet and genetically modified maize diet in terms of the number of antibody-producing cells, ConA-induced spleen lymphocyte proliferation, NK cell activity, whole blood lymphocyte subsets, delayed type hypersensitivity and thymus index(P>0. 05).
CONCLUSION: Under the conditions of this experiment, no significant effects were found on immune function of F3 SD rats through the three generation development study of genetically modified maize with CrylAb and epsps genes.
