AIM: 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. CONCLUSION: Blood peroxidation temperature is lower. The author pointed out the questions and prospects of blood preservation.

AIM: To explore the effects of different temperature and time on preservation damages in liquid blood. METHODS: Take blood sample from 10 healthy blood donors, put the fresh blood into CP2D-A liquid at 0 degrees C and 4 degrees C, and take the samples after 1 week, 2 weeks and 3 weeks, and then measured the contents of GSH-Px, TSH, LPO, the contracting protein of RBC, and membrane fluidity. RESULTS: At the same temperature, when the preservation time is prolonged, peroxidation is increased, the preservation damages are also augmented; the damages are declined when the temperature is lower during the same period, the aging of blood was more evident at 4 degrees C. CONCLUSION: Blood peroxidation temperature is lower. The 0 degrees C group is better than 4 degrees C group.
