摘　　要：目的 :研究不同来源膳食蛋白质对大鼠尿钙排出的影响。方法 :给予 SD种 级雄性大鼠 4种不同蛋白质合成饲料进行观察。结果 :谷类蛋白组与酪蛋白组 ,谷豆混合蛋白组差异有显著性 (P<0 .0 5 ) ;而大豆蛋白组与酪蛋白组和谷豆混合蛋白组差异无显著性 (P<0 .0 5 )。即优质蛋白质 (大豆和酪蛋白 )可减少尿钙排泄。结论 :食用谷类食物同时配合食用豆类 ,可预防缺钙。Objective:To study the effect of dietary animal and plant proteins on eacreting calcium from urine. Methods: Four groups of SD rats were fed on 4 different sources of proteins(wheat protein,casein,soybean protein,wheat and soybean protein mixture)for 45 days. Results: Compared with wheat protein,caseni and the mixture of wheat and soybean protein indued significantly lower excretion of calcium from ruine. Conclusions: The results suggested that fed execllent proteins can prevent the vacancy of calcium.
