Abstract:
【Objective】 To investigate the inactivation function of 25Gy X-ray irradiation on apheresis platelets’ lymphocytes and its effect on the quantity of apheresis platelets(AP). 【Methods】 Twenty healthy voluntary AP donors from January to May 2021 in our center were selected, and 2 bags of AP were donated by each of them. The APs were divided into two groups to undergo X-ray and γ-ray irradiation for 10 min. Lymphocytes were separated from AP samples, before and after irradiation, by lymphocyte separation solution to analyze and compare the effect of X-ray and γ-ray on lymphocyte proliferation. The CD41b, CD62p, blood routine and pH of APs before and 1-day/3-day after irradiation were detected. SPSS statistical software was used to analyze and compare the differences between groups by independent sample t-test. 【Results】 After 25Gy X-ray and γ-ray irradiation, the inhibition rates of lymphocytes were (98.034±1.778)% and (97.882±1.915)%, respectively.Compared with the γ irradiation group, the difference of Plt, PDW, MPV, P-LCR, PCT, pH, CD41b and CD62p between 1-day and 3-day group after 25Gy X-ray irradiation showed not statistically significance (P>0.05). 【Conclusion】 25Gy X-ray irradiation can effectively inactivate lymphocytes in APs, and the radiation effect was equivalent with γ-ray; at the same time, there was no significant influence on the quantity of APs.
