螺旋藻对缺铁性贫血的恢复实验

选纯种Ｗｉｓｔａｒ大鼠，用低铁饮食法复制缺铁性贫血（ＩＤＡ）模型，之后，用螺旋藻（ＳＰ）进行恢复试验。以硫酸亚铁为阳性对照组，以低铁饲料为阴性对照组，按ＳＰ含量由小到大分为３个实验组即实验１组（含ＳＰ１％）、实验２组（含ＳＰ８％）及实验３组（含ＳＰ１５％）。经过４周的恢复试验，结果：实验２组和实验３组贫血恢复速度最快，其次是实验１组。实验２组和实验３组体重高于阳性对照组，实验１组体重与阳性对照组接近，阳性对照组体重高于阴性对照组。提示：（１）单纯性缺铁可影响大鼠生长，致大鼠体重增长缓慢；（２）螺旋藻似具有加速大鼠体重增长的作用；（３）螺旋藻用于恢复大鼠ＩＤＡ效果显著，而且用量有一个最适宜的范围．

REPLETION EFFECT OF SPIRULINA ON IRON DEFICIENCY ANEMIA IN RATS

ron deficiency anemia(IDA)model of Wistar rats was formed by feed-ing with low iron diet.They were then equally divided into 5 groups including:group 1feeding with 99%low iron diet 1% Spirulina(Sp)dry powder],group2(92%low iron diet 8%Sp dry powder),group3(85%low iron diet 15%Sp dry powder),group 4(low iron diet 30 mg/kg FeSO4)and group5(lowiron diet).After 4 weeks experimental repletion,the mean of Hb of group 4return to normal, Hb,RBC, PCV and SF of group 2 and group 3 were hi-gher than those of group l and group 5,as high as those of group 4. TheBW of groups 2 and 3 were higher than that of group 1,group 4 and group5.The BW of group l was higher than that of group 5 and approachedthat of group 4. The results showed that:(1) Simple iron deficiency re-tarded the growth of rats;(2) Spirulina might promote the growth of rats;(3) There was an obvious repletion effect of spirulina on IDA rats.
