用原子吸收分光光度计分别对15例原发性视网膜色素变性患者、15例患者亲属和23例正常人,进行了血清铜和锌含量的测定。结果表明,原发性视网膜色素变性患者组及其亲属组的血清铜含量低于正常人(P<0.01),血清锌含量与正常人无显著差异(P>0.05)。
Fifteen cases of primary retinitis pigmentosa, 15 relatives of the patients and 23 normal persons were measured respectively by atomic absorption spectrophotometer for determination of serum copper and zinc. The results showed that serum copper levels in patients with primary retinitis pigmentosa and their relatives were lower than those in normal subjects (P <0.01), serum zinc levels were not significantly different from those in normal subjects (P> 0.05).
