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 understand the effects of middle-aged and old-aged milk powder on the intestinal microflora, serum immunoglobulin and calcium in the elderly. Methods The intestinal microflora was detected by culture method, the serum immunoglobulin was measured by the rate nephelometry and the serum calcium by chemical method. Results The bifidobacteria in the intestine of middle-aged and elderly patients were significantly increased (P <0.01), and the levels of serum IgG, IgA, IgM and serum calcium were also significantly increased (P <0.001, P <0.001, P < 0.01 and P <0.001). Conclusion The middle-aged milk powder can regulate the intestinal microflora in middle-aged and elderly people, increase immunity and prevent decalcification.
