ABSTRACT
【Objective】 To analyze the changes of activation, function and metabolism of apheresis platelets during storage. 【Methods】 Five groups of apheresis platelets(n=10per group), stored up to 5 days at 20~24℃ with agitation, were sampledat day0(4 hours within collection), 1, 2, 3 and 4, respectively to assess the activation indexes as PAC-1 and CD62P and platelet function was evaluated by thromboelastogram.The platelet counts and related parameters were determined, and the biochemical indexes such as pH, glucose, lactic acid and lactate dehydrogenase reflecting metabolism were measured and statistically analyzed. 【Results】 The CD62P (%) and PAC-1 (%) of apheresis platelets with different storage duration showed significant differences(P0.05). Significant differences were notable in platelet biochemical indexesby groups using variance analysis(P<0.05). The pH value and glucose were the lowest in platelets with 4-day storage, while lactic acid and lactate dehydrogenase were the highest. 【Conclusion】 The storagelesion of apheresis platelets occurs as the activation, function and metabolism of platelets developed as the storage prolonged.
