紫黑米提高贫血大鼠血红蛋白作用的研究

用大鼠血红蛋白(Hb)恢复方法研究紫黑米提高贫血大鼠Hb作用。给90只Wistar雄性幼鼠低铁饲料25天,复制出缺铁性贫血(IDA)模型。选出50只,随机分成低铁、白精米(寒丰)、紫黑(SX40)精米、紫黑半糙米和玉米淀粉对照(简称对照)五组,喂养30天。结果:紫黑米优于白米,紫黑半糙米优于紫黑精米。低铁和白精米组动物Hb水平不能维持。Hb恢复程度与铁摄入量、饲料含铁量呈正相关。提示紫黑米,尤其紫黑半糙米,有防治IDA作用。可能是由于紫黑米含铁量较高缘故。

THE EFFECT OF PIGMENTED RICE ON HEMOGLOBIN REGENERATION IN ANEMIC RATS

Hemoglobin (Hb) regeneration method in rats was used to prove the effect of pigmented rice on iron dificiency anemia (IDA). IDA was induced in 90 Wistar male weaning rats by feeding low iron diet for 25 days. Fifty of the anemic rats were divided into 5 groups; low iron, nonpigmented milled rice, pigmented milled rice, pigmented semibrown rice and control (compared only with the pigmented milled rice group). The result of 30 days experiment showed that pigmented rice was superior to nonpigmented rice in Hb regeneration and the semibrown was superior to the milled. Pigmented rice, especially the semibrown, was found to possess more iron than nonpigmented rice. There was a close correlation between the degree of Hb regeneration and the quantity of iron taken by rats or the quantity of iron in diets. These evidences suggested that pigmented rice had certain prophylactic and curing effect against IDA and this was probably due to its higher iron content.
