正常中老年人血浆氧化酶活性的初步观察及其意义

A preliminary study of plasma oxidase activityby spectrophotometry on the healthy middle-agedand old volunteers in Changsha

用分光光度法测定２６名中老年健康志愿者血浆氧化酶活性（ＰＯＡ），初步建立了长沙地区ＰＯＡ的正常参考值范围。此法精密度好（ＣＶ＝３．９％），操作简便、费用低廉，适用于一般实验室。

The plasma oxidase activities (POA) in 26 healthy volunteers were determined by spectrophotometry. The results showed that the POA value of the 26 cases was obviously lower (78.90±8.12U·L-1) than that in Lasla's (84±5U·L-1)(P<0.05). A preliminarty normal reference range of POA (45～60 years old) in Changsha was established. This method is an accurate (CV=3.9%), cheaper, and easy one and applicable for clinical laboratories.
