【摘要】 选汕头市市区及郊区各1所小学7～10周岁学生共180人，进行螺旋藻（SP）饮料对儿童缺铁性贫血（IDA）干预效果的试验。按性别、年龄及贫血与否配对分实验组和对照组各90人，采用双盲法给予实验组每次口服200mlI号液（含SPO．4g／L），每天二次。对照组以同法服同量II号液（除不含SP外其余配方成份与I号液相同），连续四周，于实验前及实验停止后第二天手指采血，以HicN法测血红蛋白（Hb）．结果实验组儿童Hb均值升高12，3g／L。对照组Hb无增高．贫血组儿童干预后Hb升高17．4g／L，非贫血组Hb升高5．sg／L，上升程度前者大于后者。显示SP确有提高人体Hb功能，对贫血儿童效果更优。因其配成有果味的饮料，在防止贫血中易于推广应用。更多还原
