A spinach loading experiment was performed on 9 normal subjects, 25 outpatients who were single calcium oxalate stone formers and 25 recurrent calcium oxalate stone formers. The experimental diet contained 445 mg of total oxalate, 163 mg of soluble oxalate and 115 mg of calcium. Urinary oxalate excretion was observed 2 hrs before and 6 hrs after the experimental diet was consumed. There was no significant difference in urinary oxalate excretion in preloading urine of normal subjects and stone formers. However, urinary oxalate excretion in postloading urine was significantly elevated in stone formers. This loading test is recommended as a simple and valuable screening method of hyperabsorption of oxalate on outpatients with calcium oxalate stones.
对9名正常受试者、25名单发草酸钙结石的门诊患者和25名复发性草酸钙结石患者进行了菠菜负荷试验。实验饮食中总草酸盐含量为445毫克，可溶性草酸盐含量为163毫克，钙含量为115毫克。在食用实验饮食前2小时和食用后6小时观察尿草酸盐排泄情况。正常受试者和结石形成者负荷前尿液中的尿草酸盐排泄没有显著差异。然而，结石形成者负荷后尿液中的尿草酸盐排泄显著升高。推荐这种负荷试验作为一种简单且有价值的筛查方法，用于检测草酸钙结石门诊患者草酸盐吸收过多的情况。
