[目的]当肾损伤时,观察血清中离子钙是否降低。[方法]分光光度法、离子选择电极法。[结果]肾衰患者Ca2+为(0.89±0.032)mmol/L,明显低于健康对照组(1.22±0.12)mmol/L,肾炎患者Ca2+(1.12±0.34)mmol/L,略低于正常。[结论]肾损伤患者中肾衰患者血清离子钙Ca2+明显低于健康对照组,急性肾小球肾炎患者血浆中Ca2+略低于健康组,肾损伤严重者全血Ca2+相对低于肾损伤较轻的患者。
[Purpose] To observe whether the serum ionized calcium is decreased when the kidney is damaged. [Method] Spectrophotometry and ion selective electrode method. [Results] The Ca2 + level in renal failure patients was (0.89 ± 0.032) mmol / L, significantly lower than that in healthy controls (1.22 ± 0.12) mmol / L and nephritis patients (1.12 ± 0.34) mmol / L, slightly lower than normal. [Conclusion] The serum calcium ion of Ca2 + in renal failure patients is obviously lower than that in healthy control group. The plasma Ca2 + in patients with acute glomerulonephritis is slightly lower than that in healthy group. The renal injury is more serious than in renal injury Of patients.
