A suspension of rat thymocytes was maintained in vitro for more than 12 hours with reasonably good survival. By vital staining with erythrosin and examining fixed film preparations stained by haematoxylin, the response of thymus lymphocytes to various physical and chemical factors such as heat, KCN were noted to be as expected.The susceptibility of their deoxyribonucleoprotein (DNP) to treatment with phenol and trichloroacetate was also similar to that found for thymus tissue.

建立了一个简单的胸腺淋巴球悬液的离体系统。利用四碘荧光素进行细胞直接染色或苏木素染色制得的涂片,观察了这种离体细胞对不良环境如热及氰化钾等物理或化学因素的反应是正常的,其DNP对酚—盐处理的稳定性也与由整体胸腺组织获得的相同。离体淋巴球悬液对X射线极为敏感,照射后随着时间的增长,细胞染色率及固缩率均不断增加,后者发展的速度更快,以照后6小时的变化来看,染色率随照射剂量(50伦—10,000伦)直线上升,固缩率的增加则在500伦已达极限。由DNA抽提率反映的DNP 稳定性也有下降,并且也随时间而发展。特大剂量如1万伦照射,则有性质不同的结果。对三种效应指标所能代表的意义作了讨论,认为就控制了细胞群落变化的离体系统所得结果是与前文整体实验基本相符的,即DNP稳定性降低是淋巴球直接受辐射损伤以后发展的结果。

The analysis of rose bengal-131I preparation, by PC has been investigated. Analytic conditions were determined. Chromatographic separation was carried out by the ascending technique with solvent system: n-amyl alcohol-cone, ammonium hydroxide-water (0.5:2:100) on'domestic "Xin Hua" medium speed chromatographic paper, Whatman (?) 1 or (?) 2 paper. The front was 25cm. The time was 2 to 4 hours. The method is suitable for routine quality control of the preparation. After one-dimensional chroma-tography, content of 131I- and tetraiodotetrachloro-fluorescein in the preparation can be determined at the same time.Deiodination of sample on paper has also been studied. Before chromatographic separation, the sample point should not be dried by infrared lamp, otherwise deiodi-nation will occur, and the content of iodide ion will be increased.

本文研究了玫瑰红-~(131)Ⅰ制剂的纸上色层分析,确定了适宜的分析条件。 采用“新华”中速色层纸,或Whatman № 1、№ 2色层纸,以戊醇-浓氨水-水(0.5:2:100)作为溶剂,用上行色层法展开到前沿25厘米,时间约为2—4小时。方法可用于玫瑰红-~(131)I制剂的常规质量控制分析,能同时测定制剂中的游离~(131)I~-和四氯四碘荧光素的含量。 同时观察了样品在色层纸上的脱碘现象,确定样点在色层分离前不能用红外灯烤干,否则会发生脱碘作用,使~(131)I~-含量增加。

The fluorescence lifetimes τ_((?)M) of two oarbocyanine dyes and the fluorescein dye, Erythrosine B as a function of viscosity, η, have been measured in a series of aliphatic alcohols and diols by picosecond time-resolved fluorescence spectroscopy.

The fluorescence lifetimes τ_((?)M) of two oarbocyanine dyes and the fluorescein dye, Erythrosine B as a function of viscosity, η, have been measured in a series of aliphatic alcohols and diols by picosecond time-resolved fluorescence spectroscopy. It was found that τ_((?)M) for the carbocyanines in the diols and glycerol was anomalously low. τ_(FM) varied linearly with η~(2/3) in the diols but not in monohydric alcohols. This indicates the need to treat with caution any study of viscosity dependence, where the viscosity range is produced by mixing alcohols of different classes such as ethanol and glycerol. The 2/3-power law was found to hold for Erythrosine B in monohydric alcohols.

应用10~(-12)s级时间分辨率的荧光光谱,测定了两种碳菁染料和一种荧光素染料(四碘荧光素B)的荧光寿命τ与溶剂粘度η之间的函数关系,发现碳菁染料在二元醇和丙三醇中的τ_(FM)低得反常.在二元醇溶剂中,它们的τ_(FM)与溶剂粘度η~(2/3)呈线性函数关系,但在一元醇溶剂中则并无此线性关系.由此可见,在研究染料分子的寿命与由不同系列醇(例如乙醇和丙三醇)组成的混合溶剂的粘度之间的依赖关系时,必须十分谨慎.对于四碘荧光素B,它在一元醇中的荧光寿命与溶剂粘度的关系符合2/3指数规律.
