NaF can induce significant increase of micronucleus frequency in eripheral erythrocytes of Zebrafish. Neither transgenic CryIA cotton seed powder nor regular cotton seed powder has obvious effect on micronucleus frequency in eripheral erythrocytes of Zebrafish.

腹腔注射氟化钠可以诱导斑马鱼外周血红细胞微核率的显著升高；转CryIA基因抗虫棉棉籽粉粉和普通棉棉籽粉粉一样，对斑马鱼外周血红细胞微核率无明显影响。

The mutagenicity of seed powder and seed oil of transgenic CryIA cotton to mammals and fish was evaluated in this study. The raw cotton seed powder or seed oil was mixed into mice and fish's diet. Cyclophosphamide and NaF were used as positive controls respectively. Regular cotton seed powder and seed oil were used as negative controls. The micronucleus frequency in mice bone marrow polychromatic erythrocytes and in eripheral erythrocytes of Zebrafish were assayed in this study. The sperm malformation rate in mice was also investigated.
