Quantitative ECG analysis for individual risk assessment of future myocardial infarct-results from the MARISK study
From 1980 to 1990 the authors performed an epidemiological cohort study in order to explore the predictive power of computer electrocardiogram (ECG) measurements for individual risk assessment of future myocardial infarct in combination with commonly known risk factors. Out of 7542 participants, 83 experienced a myocardial infarct during the course of the study. Multivariate logistic regression analysis revealed that vector cardiogram (VCG) measurements provide significant additional information to risk estimation which is equivalent to that of other risk factors. Measurement changes are stronger risk indicators than single measurements. The results confirm previous findings from H.V. Pipbe…

Comparative histological, histochemical, immunohistochemical and biochemical studies on oestrogen receptors, lectin receptors, and Barr bodies in human breast cancer.
The present study performed on a total of 567 cases of human female breast cancer compares the results of the biochemical assay (dextran-coated charcoal assay = DCC) for oestrogen receptor (ER) with those of several morphological methods developed for the detection of the ER or for the prediction of prognosis by use of other systems (FSA = fluorescent ligand binding assay, ER-ICA = monoclonal antibody assay for ER, LRA = lectin receptor assay using peanut agglutinin, and Barr body estimation). Whereas no correlation at all was observed among the results of the DCC and those of the FSA and Barr body estimation, the ER-ICA and the LRA showed an unanimous tendency towards higher values of ER w…
