营养缺乏

Avian embryo normal growth and development depends on all necessary nutrient from Avian eggs .As Romanoff （1972） pointed out, nutrition is critical ,no matter how deficiency or over-dose of nutrient ,It both leads to all kinds of nutritional defect ,even mortal stress .

禽胚的正常生长与发育取决于蛋提供的所有必需的营养物，Romanoff等(1972)指出，营养为本，无论是缺乏还是过量均会使胚胎出现各种营养性缺陷甚至于致命的应激。

In recent years, NAFLD animal models have been successfully established in many species such as rat, sand rat, mice, rabbit, and piglets induced by diet, total parenteral nutrition, and methionine choline-deficient. These models provide new opportunities to study the pathogenesis and treatment of metabolic syndrome associated with NAFLD/NASH.

近年来，在大鼠、沙鼠、小鼠、兔和小猪等动物种属成功地建立了食物、胃肠外营养与蛋氨酸胆碱缺乏等诱导的单纯性脂肪肝和脂肪性肝炎动物模型，这些模型为研究脂肪肝和脂肪性肝炎的发病机理与治疗提供了机会。

Actually, the development of genetically-modified products is a double-edged sword: On the one hand, it contributes to the enhancement of the world crop yield, as well as the quality, and reduction of chemical fertilizer and the pesticide use, helps solution of the famine and undernourishment in developing countries. Besides, it also promotes the development of certain related industries like pharmaceutical and chemical industries; On the other hand, it also brings the unprecedented threat for human beings. We are unaware of the potential effects in human bodies, or any unknown injury to the next generation, caused by genetic modification. Nor can we forecast what kind of influence to the extant gene will emerge.

而事实上，转基因生物技术的确是一把双刃剑：一方面，转基因技术可以提高世界农作物产量、提高质量、减少化学肥料和杀虫剂的使用、解决发展中国家的粮食缺乏、饥饿和营养不良的问题，另外，基因技术的飞速发展在很大程度上也促进了医药、化工等相关行业的发展；另一方面，它也为整个人类带来了前所未有的威胁，人们无法得知基因序列的改变会在体内引起何种潜在的变化，无法确定转基因产品是否会对下一代产生任何未知的伤害，无法预测转基因产品对现存基因会产生何种影响。
