摘要
目的:研究全血在保存过程中是否存在IL-2和IL-8的积累,保存前白细胞滤除对其保存水平的影响。方法:选10名健康捐血者,各采集 200ml全血分成2袋,其中一袋经去白细胞处理。在4℃保存不同时期测定血液中 IL-2、IL-8含量的动态变化。结果:随着保存,全血中IL-2和IL-8的浓度不断增高。经去白细胞处理后,IL-8水平在保存中无明显变化,IL-2的含量仍然增高,但在保存期末低于正常全血中的相应含量。结论:IL-2和IL-8在全血保存中存在产生和累积,而去白细胞过滤可以抑制IL-2和IL-8在全血保存中存在产生和累积,而去白细胞过滤可以抑制IL-8的升高,对预防发热性非溶血性输血反应有一定作用。
Investigate the effect of prestorage white cell filtration on the cytokines content in blood. Methods: Ten units of whole blood was divided into two parts just after blood collection:one was used as control, the other was filtrated by leukoreduction filters. All units were stored at 4℃ for 6 weeks. Immediately after filtration and every week subsequently, samples for analses of IL-2, IL-8 were obtained. Results:The amounts of IL-2 and IL-8 increased during the storage period. In filtered units, the amounts of IL-8 did not increase during the study period, IL-2 still increased but was still lower than that of unfiltered units at the end of storage. Conclusion: Many cytokines, such as IL-2 and IL-8, were generated and accumulated in blood during blood storage. Leukocyte filtration may prevent this effect to some extend. Prestorage filtration may decrease FNHTRs by preventing the accumulation of cytokines in blood.
