摘　　要：目的了解中老年奶粉对中老年人肠道菌群、血清免疫球蛋白及钙的影响。方法用培养方法检测肠道菌群,速率散射浊度法测血清免疫球蛋白,化学法测血清钙。结果服用中老年奶粉后,中老年人肠道内双歧杆菌明显增加(P<0.01),血清IgG,IgA、IgM含量及血清钙水平也显著提高(分别为P<0.001,P<0.001,P<0.01和P<0.001)。结论中老年奶粉对调整中老年人肠道菌群、增加免疫力、预防脱钙等具有一定的作用。Objective To analysis the effect of drinking milk powder for middle-aged and old people on intestinal flora, serum imunoglobulin and serum calcium. Methods The intestinal flora was detected by culture methods, serum immunaglobulin was detected by rate nephclometry and serum calcium by chemical method. Results After drinking milk powder for middle-aged and old people, most of the participators had an obvious change. The number of intestinal Bifidobacteria, the serum IgG IgA, IgM increased （ P 〈 0.01, P 〈 0. 001, P 〈 0. 001 and P 〈 0.01 ）, and calcium increased （ P 〈 0. 001 ） as well. Conclusion The milk powder for middle-aged and old people could adjust the middle-aged and old people＇s Intestinal flora, increasethe immunity and prevent losing calcium etc.
