含动物血的肉制品可防治缺铁性贫血

在人体循环血液单位容积内红细胞和血红蛋白量减少,或全血量减少均称贫血。贫血通常为某些疾病的一个症状。目前临床上多按照贫血的病因区分为失血性贫血、溶血性贫血、营养性贫血以及再生障碍性贫血等类型。缺铁性贫血属于营养性贫血,铁在机体内     

饮食扶“贫”疗效好

有统计表明,超过两成的国人患有贫血,其中两岁以内的婴幼儿和育龄期妇女贫血情况最严重。营养性贫血,主要是铁元素的大量丢失或生成不足造成的。人们往往认为,贫血就是体内"血少"。其实,这样理解是不正确的,在医学上的贫血是指血液中红细胞的数量减少和血红蛋白浓度低,使血液变稀变淡。贫血是一种症状,各种疾病都可能伴有贫血症状,称为继发性贫血。血液系统疾病以贫血为主要表现的有:再生障碍性贫血、缺铁性贫血、巨幼细胞性贫血、溶血或失血性贫血等。中老年人的贫血多为缺铁性贫血和巨幼细胞性贫血。     

贫血应该吃什么?

世界卫生组织列出的四大营养缺乏病您可知否?如果您还不太清楚,让我来告诉您,它们是:缺铁性贫血、维生素A缺乏病、缺钙和蛋白质-能量不足。今天,我们重点来跟大家谈一谈缺铁性贫血。缺铁性贫血:与营养相关的贫血贫血主要的判定指标就是血红蛋白,我们也称其为血色素。一般血色素低于正常值即可以诊断为贫血。然而,贫血只是一种症状,引起贫血的原因很多。     

贫血的原因与补“源”

据统计，目前全球有近20亿人患有贫血。我国的贫血状况更是触目惊心，女性贫血发病率为64％，约有30％～40％的婴幼儿有贫血，令人堪忧。尤其是孕妇贫血可殃及两代人……

贫血本身并不是一种疾病,更多的是其他疾病发展的结果,即一种症状。可能作为主人的你自己就贫血,或是身边有贫血的朋友,你认为贫血没什么大不了,但真正的威胁,往往隐藏在导致贫血的疾病中。     

老年人贫血的饮食调节

据有关资料显示，老年贫血患者日渐增多。老年人贫血以缺铁性贫血最为常见。铁在人体内起着重要作用，当机体缺乏铁元素时，会直接影响血红蛋白的合成而导致贫血。 专家研究发现，老年患缺铁性贫血的原因主要有两个：

中国推行铁强化酱油研究

WHO资料显示,目前全球有3亿以上人群存在缺铁性贫血问题,妇女和儿童是缺铁性贫血发生率较高的人群。我国第三次营养调查结果表明,我国各类人群均存在缺铁性贫血问题,一些地区妇女和儿童的缺铁性贫血发生率高达40％以上。全国缺铁性贫血的平均率约为15％～20％。可见我国是缺铁性贫血的高发地区。 缺铁性贫血主要表现为人体做功能力下降。如在对纺织厂纺纱工、橡胶厂割胶工等计量劳动者收入的调查中发现,缺铁性贫血人群的收入明显低于健康人群。缺铁性贫血会导致儿童辩识能力、反应时间、注意力及记忆等智能发育的迟     

Iron deficiency anemia following prenatal nutrition interventions.

PURPOSE: Iron deficiency anemia (IDA) during pregnancy and infancy is still common in developed countries, especially in low-income groups. We examined the prevalence of anemia and IDA in healthy low-income pregnant women participating in the Early Childhood Initiatives (ECI) program, and in their infants when they reached six months of age. METHODS: Pregnant women were recruited by nutritionists. In mothers, hemoglobin (Hb), mean corpuscular volume, and serum ferritin (SF) were measured at 36 +/- 2 weeks of gestation. In infants, Hb, mean corpuscular volume, SF, serum iron, total iron binding capacity (TIBC), and transferrin saturation (TS) were measured at six months of age. Thirty-one mother-infant pairs participated. RESULTS: Among the 31 pregnant women participating in the ECI program, six (19.4%) were anemic (Hb <110 g/L) and five (16.1%) suffered from IDA (Hb <110 g/L and SF <10 microg/L). Among infants, seven of 23 (30.4%) were anemic (Hb <110 g/L) and five of 23 (21.7%) suffered from IDA (Hb <110 g/L plus two of the following: TIBC >60 micromol/L, SF <10 microg/L, serum iron <5.3 micromol/L, TS < or = 15%). CONCLUSIONS: The prevalence of anemia in this group of low-income pregnant women is comparable to that in privileged women. The prevalence of IDA in infants is comparable to that observed in other high-risk groups. Effective strategies are needed to prevent IDA in vulnerable groups.     

The use of the pasty "Zdorov'e" ("Health") in the treatment of iron deficiency anemia]

Paste "Zdorovie", a product with high content of protein and assimilable iron, developed at the Moscow Institute of Applied Biotechnology, has been proved to be effective in the combined antianemia therapy. Improved hemograms and biochemical parameters were recorded in 60 pregnant women and nursing mothers suffering from iron-deficiency anemia (IDA). The data obtained have permitted the authors to recommend paste "Zdorovie" for combined treatment of IDA in pregnant women and to consider it promising in prevention of IDA in nursing mothers.

Evaluation of the effects of specialized therapeutic canned food on the course of iron-deficiency anemia in young children

A total of 25 normal children and 131 children with iron-deficiency anemia (IDA) were investigated, 53 out of 131 IDA patients served as controls and received a standard food ration for children suffering from IDA, the rest received nutrition containing medicinal canned food. The following paraclinical parameters were evaluated in all the children investigated: red blood cell and hemoglobin content, calcium concentration, the content of ascorbic acid and vitamin B1, iron metabolism indices (serum iron, general and latent iron-binding capacity of the blood serum, coefficient of transferrin saturation with iron, serum ferritin). The results of the study have shown a favourable effect of the special-purpose medicinal canned food on IDA course in young children that necessitates their wide production and practical use.     

苏氨酸铁对缺铁性贫血大鼠铁营养状况的改善

目的:探讨苏氨酸铁(Thr-Fe)对缺铁性贫血(IDA)大鼠铁营养状况的改善作用。方法:以低铁饲料饲喂雄性初断乳斯泼累格·多雷(SD)大鼠建立IDA模型,设置3个不同Thr-Fe剂量组和阳性对照组、低铁对照组、空白对照组,每组6只,每天灌胃1次,连续给药21 d,Thr-Fe剂量组分别给予8、16、32 mg/kg·bw的Thr-Fe,阳性对照组给予32 mg/kg·bw硫酸亚铁。结果:较低铁对照组,Thr-Fe高剂量组大鼠体重及血红蛋白、血清铁蛋白等血液指标显著提高(p<0.01),血清转铁蛋白(p<0.01)和总铁结合力(p<0.05)显著降低,各Thr-Fe剂量组大鼠游离原卟啉显著降低(p<0.01)。Thr-Fe高剂量组IDA大鼠各项指标改善优于阳性对照组。结论:低铁膳食补充Thr-Fe可以改善IDA大鼠的铁营养状况,提高功能铁及贮存铁含量,促进机体铁转运。Thr-Fe对IDA大鼠体重及血红蛋白等的影响呈剂量相关性,Thr-Fe对IDA大鼠铁营养状况的改善效果优于硫酸亚铁。     

Effect of Squid Ink Melanin‐Fe on Iron Deficiency Anemia Remission

ABSTRACT: The present study was designed to evaluate the effect of a new iron tonic (squid ink melanin‐Fe [SM‐Fe]) on remission of iron deficiency anemia (IDA) using a rat model of IDA. The rat IDA model was established with low‐iron diet feeding and caudal vein blooding. Then different dosages of SM‐Fe were given to the rats once a day by intragastric administration, with FeSO₄ and FeCl₃ as positive control. The content of Hemoglobin (Hb), red blood cell (RBC), hematocrit (HCT), and mean corpuscular volume (MCV) were analyzed in addition to the contents of serum iron (SI) and intracellular free erythrocyte protoporphyrin (FEP). The content of malondialdehyde (MDA) and the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH‐Px) in serum was also measured. The results showed that anemia caused by iron deficiency was established as a consequence of the low‐iron diets. SM‐Fe showed an effective restoration action by returning Hb, RBC, HCT, MCV, SI, and FEP in IDA animals to normal values. An antioxidant effect was also observed that reduced MDA level, enhanced the activities of SOD and GSH–Px in serum, and protected erythrocytes from the injury of reactive oxygen species as a consequence of SM‐Fe intake. In comparison with FeSO₄ and FeCl₃, higher bioavailability of iron and fewer side effects were also observed. In conclusion, SM‐Fe remitted iron deficiency anemia symptoms significantly, suggesting that SM‐Fe might contribute to improving hemopoietic function in IDA rats and might be exploited as a safe, efficient new iron tonic.     

芹菜叶绿素铁钠与其他补血药物功效的比较研究

目的：探讨芹菜叶绿素铁钠与其他补血剂对大鼠缺铁性贫血的效果。方法：采用低铁饲料建立大鼠缺铁性贫血(IDA)模型,给予叶绿素铁钠、血红素铁、NaFeEDTA和FeSO4,通过测定大鼠血液指标血红蛋白(Hb)含量、红细胞(RBC)数和红细胞压积(HCT),观察补血疗效。结果：在实验30d时,与模型组和FeSO4组相比,叶绿素铁钠组的Hb、RBC、HCT显著增加(P＜0.05);与血红素铁组和NaFeEDTA组相比,差异不显著。结论：芹菜叶绿素铁钠对治疗实验贫血鼠有明显的效果。     

牛磺酸对大鼠铁利用和抗氧化能力的影响

研究了牛磺酸对缺铁性贫血大鼠和正常大鼠铁利用和抗氧化能力的影响。通过对SD大鼠喂养缺铁饲料,建立缺铁性贫血大鼠模型,再给缺铁性贫血大鼠和正常大鼠灌胃0.5 g/kg牛磺酸共21 d,比较牛磺酸对正常大鼠和缺铁性贫血大鼠铁利用和抗氧化能力的影响。结果表明,牛磺酸可显著提高缺铁性贫血大鼠血红蛋白含量,提高血清铁和铁蛋白含量,提高肝脏铁含量,降低血清总铁结合力(P<0.05);可提高缺铁性贫血大鼠抗氧化能力,在补铁的同时添加牛磺酸效果更佳。添加牛磺酸对正常大鼠铁利用和抗氧化能力的提高效果不显著(P>0.05)。因此,牛磺酸对缺铁性贫血大鼠铁的利用和抗氧化能力的提高效果优于正常大鼠。

将受试学生分为正常（NA）组、铁缺乏不贫血（IDNA）组和缺铁性贫血（IDA）组,测定铁强化酱油干预前后学生的铁营养指标和认知能力水平。结果表明,干预后,IDA组血红蛋白Hb、血清铁蛋白SF水平均显著升高（P＜0.05）,IDNA组的SF水平显著升高（P＜0.05）,而NA组的Hb、SF水平无明显变化（P＞0.05）。干预后,IDNA组记忆再认量表分显著增加（P＜0.05）,IDA组的基本认知能力、知觉速度、心算效率和记忆再认能力均显著增加（P＜0.05）,而NA组的各项基本认知能力在干预前后均无统计学差异（P＞0.05）。干预后IDA组学生的托尼测试得分增加,但与NA组比较仍有显著差异（P＜0.05）。铁强化酱油干预可以有效改善铁缺乏学生的铁营养状况,对铁缺乏不贫血和缺铁性贫血学生的认知能力也有明显的改善作用。     

Food fortification strategy--preventing iron deficiency anemia: a review

Iron deficiency anemia (IDA) is a significant challenge in developing countries. It increases the risk of premature delivery and low birth weight. In children, IDA retards growth, impairs cognitive performance, and reduces physical activity. It also accelerates the mortality and morbidity rate in women. The key factors responsible include dietary elevated iron demand, socioeconomic, and disease status. To overcome IDA, disease control measures, dietary diversification, supplementation and iron fortification in food have been adopted. Iron fortification in food is considered a long term and sustainable strategy in the present scenario. For an efficient fortification program, the combination of iron fortificants and food vehicle must be safe, acceptable, and consumed by the target population. Moreover, it should not adversely affect acceptability and stability of the end product.
