在进行转Bt-基因抗虫棉棉仁粉对鲤鱼营养学试验的基础上 ,继续喂养 6周 ,在不同时期取鲤鱼血液 ,测定了血像、谷丙转氨酶、尿素酶及血红细胞微核率这些反映毒性效应的指标 ,并选取部分组织器官进行了组织病理学检查 ,对有关指标进行了统计学分析 ,各试验组和普通棉对照组之间均无显著性差异 ;鲤鱼肾、心脏、小肠及肝胰脏组织切片无明显病理性变化。由此表明转Bt-基因抗虫棉棉仁粉经脱酚处理后 ,对鲤鱼的毒性效应不明显
On the basis of carrying out the nutrition test of Bt-Bt cotton cottonseed meal on common carp, we continued to feed for 6 weeks and took the carp blood at different times to determine the changes of blood picture, alanine aminotransferase, urease and micronuclei of erythrocytes These indicators reflect the toxic effects, and selected part of the tissue and organ histopathological examination, the relevant indicators were analyzed statistically, the experimental group and the control group of ordinary cotton no significant difference; carp kidney, heart, small intestine And hepatopancreas tissue sections no obvious pathological changes. The results showed that the toxic effects of transgenic Bt-cottonseed cottonseed meal on carp were not obvious
