| | This infant cereal chiefly consisted of rice meal, fullfat milk powder, rice germ and dried yeast, and fortified with ferrous lactate and calcium carbonate. This mixture contained 14.1% protein, 8.6% fat, 64.3% carbohydrate, 750mg% calcium, 10mg% iron, 1.0mg% zinc and proper amount of various kinds of vitamins.1. Growth test; 84 weaning SD rats were randomly divided into 6 groups:(A) Infant cereal group;(B) Control I; (C) Control II; (A') Infant cereal group; (B') Control I; (D) Casein group. Th... | | 本实验是以大米粉为主,混合适量全脂奶粉,全脂米胚芽、干酵母,并强化碳酸钙和乳酸亚铁研制一种营养成分合理、能促进婴儿生长发育、预防缺铁性贫血和佝偻病且价格便宜的婴儿辅助食品。动物实验结果表明,实验组(A组)大鼠的增重与对照Ⅰ(B组)无显著差异(P>0.05),但平均增重超过B组(对照Ⅰ)9g左右,与对照Ⅱ(C组)比较增重平均超过60g,有极显著差异(P<0.01)。FE、CE及PER的统计结果与增重一致,且实验组无贫血和脱钙现象。氮代谢试验结果表明,实验组AO、TD、BV及NPU分别为97.47%、98.08%、85.73%和84.09%,B纽分别为97.29%、97.81%、87.51%和85.59%,两组无统计学差异;肝氮、体氮含量及体氮回复也均无显著差异,都达正氮平衡。 | | 文摘来源 | | Objectives To determine the effects of supplementing biscuits fortified with calcium (Ca) and vitamin D (VD), iron (Fe), vitamin C (VC) and zinc (Zn) to pregnant women from the 5th month of gestation until delivery on their health, and to explore a way to improve their Ca, Fe and Zn nutritional ststus during pregnancy Methods A total of 313 healthy and primary pregnant women were enrolled and divided into five study groups based on their order visiting the hospitals for prenatal care Each woman of the... | | 目的 研究孕中期单纯补钙和同时补铁、补锌对孕妇健康的影响 ,探讨妊娠期间改善钙、铁、锌营养状态的途径和方法。方法 选择初产健康孕妇 313名 ,按孕妇入院体检顺序循环分为 5个试验组。试验组给予强化饼干至分娩时止 ,饼干中分别强化维生素D(VD) ,钙、锌、铁和维生素C。对照组系在前 5组均收集到 1个样品时 ,在医院随机选择 1例临产非试验对象。结果 孕妇膳食钙、锌、铁的摄入量平均仅达到每日膳食中营养素供给量的 47 7%、5 4 7%和 86 7%。孕中期孕妇贫血患病率高达 35 2 % ,补铁能有效地改善营养性贫血 ,试验前钙 +铁 +锌 +VD组和钙 +铁 +VD组的贫血率分别为 35 3%和 40 7% ,试验后则降低到 0 0 %和 4 0 % ,而没有补铁组试验后贫血率仍较高。钙补充组 ,血浆钙均值都有所上升 ,以钙 +VD组最为明显 ,就补钙而言 ,单纯补钙组效果优于其他组。血浆锌水平随孕期进展而下降 ,补锌对血浆锌有一定的改善作用 ,而血清碱性磷酸酶活性随孕期进展而上升。分娩 2个月后各试验组和对照组母亲的桡骨和尺骨骨密度差异无显著性。单纯补钙组母体桡骨和尺骨骨密度与钙摄入量有显著... | | 文摘来源 | | Objectives The purpose of the present study is to determine the effects of supplementing the biscuits fortified with calcium (Ca), iron (Fe) and zinc (Zn) for pregnant women from the 5th month of gestation until delivery on the growth and development of fetus and to explore the best way to improve infant growth Methods A total of 313 healthy and primary pregnant women were enrolled and divided into five study groups based on their order visiting the hospitals for prenatal care Each woman of the study gr... | | 目的 以孕妇为对象 ,研究孕中期单纯补钙和补钙同时补铁和 /或锌对婴儿生长发育的影响。方法 选择初产健康孕妇 313名 ,分别强化维生素D(VD)、钙、铁和锌 ,从孕 5月至分娩时止。分娩时测量胎盘重量、胎盘和脐带血中微量元素的含量、新生儿的出生体重和身长。结果 对照组胎盘重量最大 ,钙和多种微量元素的含量较低 ,而钙 +铁 +锌 +VD组相反 ,并且对照组的胎盘重量(5 5 1 1± 6 4 2 )g显著大于钙 +铁 +锌 +VD组 (4 6 7 1± 36 6 )g。脐血中血红蛋白含量显著高于母血 ,碱性磷酸酶活性差异无显著性 ,脐血血浆中钙、铁、锌含量均高于母血。婴儿的生长发育结果显示 ,钙 +铁 +锌 +VD组新生儿的出生体重 (3 5 3± 0 33)kg和身长值最大 ,并且出生体重显著大于对照组的 (3 2 8± 0 5 4)kg。结论 孕期联合补充钙、铁、锌 ,使其达到或接近每日膳食中营养素供给量 ,这是改善婴儿生长发育的最佳方式。 | | 文摘来源 | |   | | << 更多相关文摘 |
