摘要
本文研究了转基因棉籽的食用安全性以及对动物肌体抗氧化系统的影响。实验中无动物死亡,并且所有动物都表现正常。结果表明,食用转基因棉籽的处理组与食用非转基因棉籽的对照组相比,动物体重增长率及食物利用率、血液生化指标、脏器重等均无显著差异。受试大鼠的大体解剖及脏器的组织切片镜检结果,均未发现异常病理性改变。大鼠在食用转基因棉籽和非转基因棉籽后,肌体的抗氧化酶活性无明显差异。通过对大量结果的统计分析,显示转基因棉花棉籽与非转基因棉籽在营养学方面具有实质等同性。
The food safety of transgenic cottonseed and their effects on the antioxidant system of rat were examined. There was no mortality in the study and all animals appeared healthy. The results showed that there are no significant differences in weight gain and feed intake, blood biochemical indices and organs weights between rats consuming transgenic cottonseed and conventional cottonseed diet as control. All rats appear normal in anatomy and histopathology. Similarly, there are no significant differences in antioxidant enzyme activity among groups. The results of numerous analytical measurement demonstrated that the transgenic cottonseed is nutritionally equivalent to the conventional one.
