[Exfoliative cytology by the Sayk sediment chamber method].
It is reported on methodical examinations by means of the sediment chamber technique after Sayk in the exfoliative cytology of tumours of the urinary bladder. By means of this technique the possibility of an improved cytomorphological judgment is given, since the criterial of the enrichment of cells, the immediate preparation of cells and the avoidance of mechanical damages by centrifugation are guaranteed.
Previous studies on the serological diagnosis of rotavirus infection have utilised locally produced antibodies. In this study we have compared two commercially produced assays, an ELISA (Rotazyme, Abbott) and a newly developed assay--solid phase aggregation of coupled erythrocytes (SPACE) (Wellcome Research Laboratories), with electron microscopy (EM). The SPACE test appeared less sensitive than EM. The ELISA was shown to be as sensitive as EM but more versatile. Our experience suggests that the ELISA could be successfully incorporated into the routine of any diagnostic laboratory.
