Abstract

During liquid storage of platelet concentrates (PC) at 277 K (4 degrees C) and 295 K (22 degrees C) prepared from ACD-AG-blood the cells lost their ability to hypotonic shock response (HSR) within 3 days. The HSR maintained on the initial level during 3 days in platelets as platelet rich plasma (PRP) at 295 K, but fell significantly at 277 K. The number of platelets decreased more rapidly at room temperature than at 277 degrees K, but a statistical difference did not exist. At room temperature the pH-fall was accelerated and came to 6.5 even after 1 day storage of PC but only after roughly 5 days in PRP.

摘要

在由ACD - AG血液制备的血小板浓缩物（PC）于277 K（4℃）和295 K（22℃）进行液体储存期间，细胞在3天内丧失了对低渗休克反应（HSR）的能力。在295 K下，血小板作为富血小板血浆（PRP）时，HSR在3天内维持在初始水平，但在277 K时显著下降。血小板数量在室温下比在277 K时下降得更快，但不存在统计学差异。在室温下，PC储存1天后pH值下降加速，甚至降至6.5，而PRP大约在储存5天后才出现这种情况。
