缺铁性贫血(iron deficiency anemia, IDA)是由于体内储存铁缺乏而影响血红蛋白合成所引起的一种常见贫血。这种贫血特点是骨髓、肝、脾及其他组织中缺乏可染色铁,血清铁浓度和血清转铁蛋白饱和度均降低。典型病例贫血是属于小细胞低色素型。铁缺乏症根据体内缺铁的发展过程,分体内储存铁耗尽(iron depletion,ID)、缺铁性...
缺铁性贫血是指体内铁含量不足时发生的贫血。患贫血时,人的红细胞(RBC)数量比正常人低。 红细胞内的血红蛋白担负者向全身输送氧气的功能。铁是合成血红蛋白的重要原料。铁不足时,血红蛋白和红细胞生成减少,从而导致贫血。补铁治疗通常会使贫血好转。 体征和症状 初期,缺铁性贫血的儿童可能没有任何症状。如果未能及...
机体对铁的利用是极为有效和节省的,每日合成血红蛋白需要的铁(20-25mg),大部分来自衰老的红细胞破坏后释放的铁。 缺铁对细胞的分裂、增殖影响较小,故红细胞数量减少程度不如血红蛋白减少明显。 血清铁(serum iron,SI) 血清中的铁一部分与运铁蛋白结合,另一部分呈游离状态,检测后者的含量即为血清铁测定。受生理...

Given the well-established links between iron-deficiency anemia (IDA) and impaired dopaminergic function in animal models, added to the evidence that IDA during early infancy is associated with lasting neurofunctional, sensory and cognitive effects, we evaluated the potential effects of early IDA on ...
铁是人体内含量最丰富的微量元素。儿童缺铁可导致铁缺乏症(iron deficiency, ID)或缺铁性贫血(iron deficiency anemia, IDA),影响儿童生长发育,不利于大脑认知功能发展,使运动能力降低、免疫功能下降及影响其他营养元素代谢等。 引起缺铁性贫血的原因 : 1)先天储铁不足:早产、双胎或多胎,胎儿失血和孕母严重缺铁等。
Iron-deficiency anemia is a common, easily treated condition thatoccursif you don’t have enough iron in your body. Low iron levels usually are due to blood loss, poor diet, or an inability to absorb enough iron from food. Ad Iron is needed to produce hemoglobin, a type of protein found...
