Influence of Genetically modified Soya on the Birth-Weight and

Survival of Rat Pups

转基因大豆对幼鼠出生重量和生存状况的影响

By Irina V.Emakova

Abstract

Investigation of the influence of GM soya on the birthrate and survival of the offspring 后代of Wistar rats2 were performed. A group of female rats were fed GM soya flour before mating 交配and pregnancy. The control group of females were fed traditional soya and the third group of females, the positive control group, received feed without any soya. The weight and the mortality死亡rate of the newborn pups were analyzed. The study showed that there was a very high rate of pup mortality (55.6%) in the GM soya group in comparison with the control group and the positive control group (9% and 6.8% respectively. Moreover, death in the first group continued during lactation哺乳, and the weights of the survivors are lower those from the other two groups. It was revealed in these experiments, that GM soya could have a negative influence on the offspring of Wistar rats.

摘要

我们进行了转基因大豆对大白鼠后代出生率和生存状况的影响研究。一组母鼠在交配和怀孕前被喂食转基因大豆粉。母鼠的控制组被喂食传统大豆,第三组母鼠,即积极控制组,吃的食物没有任何大豆。我们分析了新生幼鼠的体重和死亡率。研究表明相比控制组合积极控制组的死亡率(分别是9%和6.8%),转基因大豆组幼鼠死亡率(55.6%)很高。另外,转基因大豆组的幼鼠死亡率在哺乳期还在继续,存活幼鼠的体重也比其他两组幼鼠要轻。这些实验表明,转基因大豆对大白鼠后代可能有消极的影响。

Introduction

The term genetically modified organism (GMO3s) refers to plants, microbes and animals with genes transferred from other species in order to produce certain novel characteristics (for example resistance to pests, or herbicides) and are produced by recombinant DNA technology. Four main sources of the hazards危险of GMO are discussed by scientists worldwide: 1) those due to the new genes, and gene products introduced; 2) unintended effects inherent内在的to the technology; 3) interactions between foreign genes and host genes; and 4) those arising from the spread of the introduced genes by ordinary cross-pollination异花授粉as well as by horizontal gene transfer (World Scientists’ Statement 2000).

介绍

术语“转基因生物”指的是拥有从其他物种传递来的基因的植物、微生物和动物,转移基因是为了产生某些新的特点(比如抗病虫,或抗除草剂),并且是由重组DNA 技术产生的。全世界的科学家讨论了四种转基因生物风险的主要来源:1)那些因为新的基因,以及引入的基因产品导致的风险;2)技术内在的无意间的影响;3)外来基因和宿主基因的相互作用;4)因为普通的异花传粉和水平基因传递导致的引入基因传播产生的风险(世界科学家声明,2000年)
