简介：为freeze-dried人血小板的一个水和过程在样品的1ml上被学习。恢复率，吝啬的血小板卷(MPV)，和血小板分发上的prehydration持续时间，prehydration温度，和水和答案的效果宽度(PDW)被调查。集体变化也在prehydration过程期间被学习。三prehydration持续时间：0，1.5，和3.5h，和二个水和答案：血小板穷人血浆并且缓冲磷酸盐盐(PBS)，被测试。它被发现那：(1)prehydration具有意义；(2)prehydration的1.5h最好比3.5完成prehydration的h；(3)作为一个水和答案，血小板穷人血浆比PBS更好表现了。结果上的prehydration持续时间和温度的影响被学习。有几乎35和37°C之间的没有差别。在测试的所有prehydration持续时间之中，15，30，60，90，和120min，最好的结果与15min的时间持续时间被完成。在每测试的结束的prehydrated血小板的重量被测量，水内容是计算的。在prehydration的15min以后，在样品的水内容在附近(4.8±0.01)%并且(5.27±0.29)%(w/w)相应于35和37°C的条件分别地。这些结果将对哺乳动物的房间的freeze-drying上的进一步的研究有用。
