An aggregometer technique was used to study urease-induced crystallizations in synthetic urine and human urine from healthy subjects and patients with chronic spinal cord injuries. The two different phases of crystallization, calcium phosphate and magnesium ammonium phosphate, were easily evaluated with a single assay using this technique. The crystallization of calcium phosphate and magnesium ammonium phosphate varied markedly among the different urine specimens after incubation with urease. The turbidity curves from human urine were divided into four patterns. We assumed that the variations in the patterns of the turbidity curves appeared to be mainly due to differences in the composition of the urine and in the original pH, and that the calcium and magnesium concentrations were very important in the urinary constituents.
采用凝聚仪技术研究脲酶诱导的合成尿液以及健康受试者和慢性脊髓损伤患者的人尿液中的结晶情况。使用该技术通过单一测定法就能轻松评估结晶的两个不同阶段，即磷酸钙和磷酸镁铵。与脲酶孵育后，不同尿液标本中磷酸钙和磷酸镁铵的结晶情况差异显著。人尿液的浊度曲线分为四种模式。我们认为，浊度曲线模式的差异似乎主要归因于尿液成分和初始pH值的不同，而且钙和镁的浓度在尿液成分中非常重要。
