【摘要】 本文使用天然优质铁源动物血和肝来预防幼童贫血取得较好效果。试验共进行10周,将71名血红蛋白浓度低于12g/dl的健康全托幼儿分为三组:A组儿童每周摄入加有动物血、肝的试验膳食五天,B组进餐与A组完全相同,仅每天加服维生素C100mg;C组作为对照组。A、B组儿童身高、血红蛋白浓度、血清运铁蛋白浓度增高值和全血游离红细胞原卟啉下降值均显著高于C组,A、B组之间无显著差异。结果表明,本文营养措施简便有效,安全可行,容易普及,是一种长期预防营养性缺铁性贫血的有效措施。更多还原

【Abstract】 In the present article the effects of animal blood and liver on the status of iron nutrition in preschool children were studied.71 apparently normal children in a kindergarten, aged 3-7 years, were selected for feeding trial. All of them were undergone physical examination to verify the absence of hookworm infestation and chronic diseases, but having a bit lower hemoglobin concentration (Hb<12g/dl).The children were assigned by randomized block according to their age into three groups:Group A--fed on diet containing animal blood and liver;Group B--fed on diet like group A plus 100 mg ascorbic acid per day;Group C--fed on diet like group A, but containing corresponding protein foods instead of animal blood and liver, namely control group.Feeding trial was carried out from Monday to Friday per week for 10 weeks.Results indicated that the increments of height, hemoglobin concentration and serum transferrin and the decrement of free erythrocyte porphyri-nes of the two experimental groups were statistically significantly greater than those of the control group.From the above results and our previous findings it was concluded that the use of the foods rich in iron being higher availability, such as animal blood and liver, was an acceptable and effective approach for long to prevent children from afflicting with the iron deficient anaemia.更多还原
