纳米碳酸钙对大鼠骨骼和血钙的影响

目的:探讨纳米碳酸钙的补钙效果。方法:选用3周龄离乳的SD大鼠40只,雌雄各半,随机分为4组:基础组(低钙组)、碳酸钙组、螯合钙组、纳米碳酸钙组,进行28d饲养实验。结果:补钙组的股骨长、股骨重、血钙均高于基础组。螯合钙组、纳米碳酸钙组的股骨长、股骨重与基础组比较,差异有显著性(P<0.05)。血钙含量,补钙组与基础组比较,差异有显著性(P<0.05)。结论:纳米碳酸钙是一种良好的钙源,可用于食品添加剂和补钙药物。

Effect of Nanometer Calcium Carbonate on the Skeletal and Serum Calcium in Rats

Objective To explore the effect of nanometer calcium carbonate on the efficacy of calcium supplement.Methods Forty 3-week old weaning SD rats were randomly divided into four groups:basal low calcium group,calcium carbonate group,calcium amino acid chelate group and nanometer calcium carbonate group,half male and half female.They were fed 28d.Results The femur weight, femur length and serum calcium were higher in the supplemented with calcium groups than that in the basal low calcium group.The femur weight and femur length of calcium amino acid chelate group and nanometer calcium carbonate group had significant differences compared with basal low calcium group(P<0.05).There were significant differences of serum calcium concentration between the supplemented with calcium groups and basal low calcium group(P<0.05).Conclusion Nanometer calcium carbonate is a good calcium resource and can be used in food additives and medicines.
