Abstract

Zinc reduced and citrate promoted the urease-induced pH increase in synthetic urine. Secondary to this, the precipitation of magnesium ammonium phosphate and calcium phosphate was influenced. Independent of this pH-related effect, zinc also increased the precipitation of magnesium ammonium phosphate and decreased the calcium phosphate precipitation. These observations were not totally reproducable in human urine.

摘要

锌可降低而柠檬酸盐可促进脲酶诱导的合成尿液pH值升高。其次，这会影响磷酸镁铵和磷酸钙的沉淀。独立于这种与pH相关的效应之外，锌还增加了磷酸镁铵的沉淀并减少了磷酸钙的沉淀。这些观察结果在人尿中并非完全可重复。
