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。

Flocculous sludge was present in 1# digester, whereas granular sludge of 0.5-1.0mm and 1.0-3.0mm in diameter was incubated in 2# and 3# digesters respectively. Enumeration of different microbial physiological groups was conducted by MPN method. From observation of light microscope, SEM and TEM revealed the predominant bacteria of various groups, and element composition of granular sludge was analysed by EDXA.
