目的 :探讨急性期脑梗死患者血清Mg2 +的变化及影响机制。方法 :对 48例脑梗死患者根据梗死面积大小分为 <3cm2 (A组 )和≥ 3cm2 (B组 )两组 ,并选正常对照组 30例 ;A、B组病例分别于发病后 1～ 3天(急性期 )和发病后 2 1～ 2 8天 (恢复期 )在清晨各采集静脉血 2ml,正常健康者为体检时采取 ;使用美国Tech niconRA - 10 0 0生化分析仪采取络合指标剂 (Calmagite) ,比色法分析。结果 ;急性期A、B两组血清Mg2 +水平与恢复期A、B两组及正常对照组比较有显著差异 (P <0 .0 1) ;急性期A组与B组血清Mg2 +水平比较无显著差异 (P >0 .0 5 )。结论 :血清Mg2 +水平下降与梗死面积大小无明显相关性
Objective: To investigate the changes of serum Mg2 + in patients with acute cerebral infarction and its mechanism. Methods: Forty-eight patients with cerebral infarction were divided into 3cm2 (group A) and 3cm2 (group B) according to the size of infarction. Thirty patients in control group were selected. Day (acute phase) and 2 1 ~ 28 days after onset (recovery period) 2ml blood samples were collected in the early morning, respectively, and normal healthy subjects were taken during the examination. The complexation index was measured by Tech niconRA - Calmagite, colorimetric analysis. Results The levels of serum Mg2 + in A and B groups were significantly different from those in A and B groups and normal control group (P <0.01) in acute phase. The levels of serum Mg2 + in A group and B group in acute phase were significantly different No significant difference (P> 0.05). Conclusion: There is no significant correlation between serum Mg2 + level and infarct size
