对比共沉淀铁锌钙镁与几种铁剂的铁吸收，为是否值得深入研究决策作根据。用血清铁法，在同一人吃不同铁剂，测定吃后3小时血清铁增加值。结果40分钟吃28mg Fe的焦磷酸铁糖，共沉淀铁锌钙镁糖，药用小儿复方四维亚铁散，试剂FeSO4·7H2O的血清铁增加值分别为2.7，5.1，5.5和7.8μmol/L。20分钟吃20mg Fe的焦磷酸铁加菜，加三氯化铁的酱油，沉淀铁锌钙镁加菜分别为2.8，3.3，3.6μmol/L。共沉淀铁锌钙镁是一种能符合WHO要求的产品，但要推广这种市场上没有又极其需要的产品，必须花费大量资金做深入研究工作，而这种花费是值得的。%Comparing the iron absorption of coprecipitation of iron, zinc ,calcium and magnesium and several iron agent to provide decision basis for if this topic has further studying value. One person eat different iron agents and then use serum iron method to test the serum iron increased value after 3 hours. The test results show that after 40 minutes of eating coke sugar iron phosphate , pediatric compound four medicinal ferrous powder, FeSO4·7H2O agent of 28 mg Fe, the increasing values of serum iron are 2.7,5.1,5.5 and 7.8μmol/L and after 20 minutes of eating Ferric pyrophosphate dish, ferric chloride contained soy sauce, precipitation of iron, zinc, calcium and magnesium dish of 20 mg Fe , the increasing values of serum iron are 2.8, 3.3, 3.6μmol/L.We conclude that coprecipitation of iron, zinc, calcium and magnesium is the product which meets the requirement of WHO. This kind of product is very few but extremely needed in the market, so the promotion must spend a large amount of funds and further work , however, it worth.
