ABSTRACT
<p><b>AIM</b>To examine the effects of different temperature protection on measures on preservation damages in liquid blood and explore the corresponding.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>Blood peroxidation temperature is lower. The author pointed out the questions and prospects of blood preservation.</p>
