title: [A preliminary study of plasma oxidase activity by spectrophotometry on the healthy middle-aged and old volunteers in Changsha].
abstract: 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 +/- 8.12 U.L-1) than that in Lasla's (84 +/- 5 U.L-1) (P < 0.05). A preliminary 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.
