It has been suggested that cation exchange resins might be helpful in urinary stone prophylaxis. The effect of the cation exchange resin Dowex 50 WX8 upon calcium absorption and urinary excretion in guinea pigs was investigated. The mean fecal calcium concentration was very close in the Dowex-treated and control animals and the urinary calcium concentration was not reduced in the resin-treated animals. These findings suggest that Dowex was ineffective in binding calcium in the gastrointestinal tract.
有人提出阳离子交换树脂可能有助于预防尿路结石。研究了阳离子交换树脂Dowex 50 WX8对豚鼠钙吸收和尿排泄的影响。经Dowex处理的动物和对照动物的粪便钙平均浓度非常接近，树脂处理的动物尿钙浓度并未降低。这些发现表明，Dowex在胃肠道中结合钙的效果不佳。
