|
【医学教育论文】作者:康皞 康虹 康润梅 齐子芬【摘要】 目的:探讨视网膜挫伤后,各期血清硒含量的变化及其机制。方法:将195例视网膜挫伤病例按病程分为3组,每组65例,将视网膜挫伤分为急性期(伤后7 d以内)、恢复期(伤后8~20 d)、陈旧改变期(伤后21~45 d);采肘静脉血,用JY-70(Ⅱ)合并型等离子体发射光谱仪测定血清硒含量,并与200例无视网膜挫伤的健康者对照比较,进行统计学处理。结果:血清硒含量在急性期、恢复期、陈旧改变期都减少,与正常组比较差异有统计学意义(P<0.01)。结论:根据血清硒含量变化,在治疗上给予含硒的药物或食物,可能有助于提高视力。 【关键词】 视网膜挫伤;血清硒;动态改变;含量 Abstract Objective: To explore the developable changes of serum selenium and its mechanism in each stage of retinal contusion. Methods:195 cases of retinal contusion were divided into 3 groups(65 cases for each): the acute stage (within 7 days after contusion),the recovery stage(within 8-20 days after contusion)and the obsolescent change stage(within 21-45 days after contusion).Cubital vein blood samples were determined with the JY-70(II) consolidated plasma emission spectrograph and compared with those in 200 normal controls and then statistic an
