Abstract
The distinction between age-related and pathological laboratory findings in elderly is most important to diagnosis and treatment of disease. 111 pensioners (77 females, 34 men) are investigated. Pathological laboratory findings are more frequently than expected. In each case there are hints to pathological events (disease or due to treatment).

Abstract
Chinese hamster ovary (CHO-9) and HeLa MR cells lack detectable amounts of O6-alkylguanine DNA alkyltransferase (phenotypically Mex-) and are hypersensitive to the toxic effect of N-hydroxyethyl-N-chloroethylnitrosourea (HeCNU), as compared to Mex+ derivatives. Microinjection of size-fractionated polyA+ mRNA extracted from HeLa S3 (Mex+) into CHO-9 and HeLa MR cells, or from ataxia telangiectasia (Mex+) into HeLa MR cells, gave rise to an increase in survival following treatment with toxic doses of HeCNU. Transient complementation of the Mex- phenotype was achieved with an RNA population 0.8-1 kb in size.

Abstract
Protein kinase CKII (i.e. casein kinase II, CKII, NII) is expressed at a higher level in rapidly proliferating tissues and in solid human tumours (e.g. colorectal carcinomas) when compared to the corresponding non-neoplastic colorectal mucosa. This could be shown by (a) Western blotting of cellular extracts from solid tumours followed by immunostaining with an anti-CKII polyclonal antibody, (b) immunohistochemical staining of cells from tissue sections and (c) by activity measurements using the CKII-specific synthetic peptide (RRRDDDSDDD). The maximum observed activity in the colorectal carcinomas investigated was up to eightfold higher in the tumour specimens than in the non-neoplastic tissue (i.e. colorectal mucosa). The activity range was between 33-350 U/mg protein and in the case of colorectal mucosa 13-106 U/mg protein. The amount of CKII determined in the individual tumours was in the range 0.4-1.6 nmol/g tissue.
