根据战备贮存的需要,对于冻干人血浆的效期控制和贮存条件,是需要进一步研究解决的一个问题。为了了解经过长期贮存的制品质量情况,我们对一九六六年至一九七四年生产的冻干人血浆,进行了抽查比较。历年抽查2批,按常规进行真空度、水份、溶解度、热稳定性及电泳等项测定,结果见表1及图1至图4,并加说明如下: 1.真空度:除六八年2瓶样品未抽真空外,其余历年各瓶样品的真空度仍然良好。 2.水份:按卡氏法测定,六九年以前制品水份有所升高,达到0.96-1.40%(原测同批水份均在1%以下),七○年以后各瓶制品符合要求。
According to the needs of combat readiness storage, the control and storage conditions of freeze-dried human plasma are issues that need further study to solve. In order to understand the quality of the products after long-term storage, we compared random sampling of lyophilized human plasma produced from 1966 to 1974. Random checks of the past two batches, according to the conventional vacuum degree, water solubility, thermal stability and electrophoresis and other items, the results shown in Table 1 and Figure 1 to 4, and added as follows: 1. Vacuum: In addition to six or eight years 2 bottles of samples were not vacuum, the remaining vacuum samples of each bottle is still good. 2. Moisture: According to the Karl Fischer method, before 1960, the product moisture has risen to 0.96-1.40% (original measured the same batch of water are below 1%), after 70 years the bottle of the product line Claim.
