title: [Effects of different temperature and time on the period of validity and quality in blood preservation].
abstract: OBJECTIVE
  To examine the effects of different temperature protection on measures on preservation damages in liquid blood and explore the corresponding.
  
  
  METHODS
  Take equal half blood samples from 10 healthy blood donors and divided each sample into two groups, put the fresh blood into CP2D-A solution at 0 degrees C and 4 degrees C, respectively and take the samples 21 days and 42 days, later and then measured the contents of membrane phospholipids with shafig-UR-rehman method, CaM with purification PED test, LPO with spectrophotometry.
  
  
  RESULTS
  At the same temperature, when the preservation time was prolonged, peroxidation was increased, the preservation damages were also augmented; the damages were declined when the temperature was lower during the same period, the aging of blood was more evident at 4 degrees C.
  
  
  CONCLUSIONS
  Blood peroxidation temperature is lower. The author pointed out the questions and prospects of blood preservation.
