ABSTRACT

Objective To investigate the effect of 60Co γ-ray irradiation on the quality of theleukocyte-filtrated red blood cells suspension.Methods Thirty bags of leukocyte-filtrated red blood cells were randomly divided into irradiation group(n =15) which was given 60Co γ-ray irradiation and control group(n =15) which was not given 60Co γ-ray irradiation.The content of extracellular K +,Na +,free hemoglobin (FHb),adenosine triphosphate (ATP) and 2,3-diphosphoglyceric acid (2,3-DPG) and pH value of the leukocyte-filtrated red blood cells were detected in the two groups.Results The content of K+,Na+,FHb,ATP,2,3-DPG and pH value in irradiation group was (5.20 ± 0.37) mmol · L-1,(140.22 ± 0.05) mmol · L-1,(0.44 ±0.04) mg· L-1,(5.18 ± 0.13)μmol· L-1,(3.34±0.30) mmol· L-1 and 6.85±0.02;the content of K +,Na +,FHb,ATP,2,3-DPG and pH value in the control group was(5.00 ± 0.40)mmol · L-1,(140.47 ± 0.83)mmol · L-1,(0.42 ± 0.08) mg · L-1,(5.22 ± 0.06) μmol · L-1,(3.56 ± 0.52) mmol · L-1 and 6.84 ± 0.05;there was no statistic difference in the content of K +,Na +,FHb,ATP,2,3-DPG,and pH value between the two groups(t =1.93,-1.67,-1.64,-2.02,1.77,1.82;P ＞ 0.05).Conclusion 6o Co γ-ray irradiation of the leukocyte-filtrated red blood cells can not effect the activity and function of red blood cells.
