[The red blood cell aggregation in men with coronary risk factors].

1. The in vitro test for red blood cell aggregation has been improved, the coefficient of variation was decreased to 14.2%. 2. By the improved method the earlier findings were confirmed with high statistical significance that heavy smokers have a significantly higher red blood cell aggregation value in comparison with nonsmokers. 3. It could be shown that other coronary risk factors, especially hypercholesterolaemia, increase the aggregation value too. 4. The aggregation of red blood cells increases in the presence of several coronary risk factors in the same patient to higher values than expected from the addition of the aggregations caused by single risk factors.

Critique of the "critical mass" hypothesis of the regeneration of liver cells.

The hypothesis that the regulation of liver cell regeneration is triggered by the critical mass of the cells has been examined. However, examination of the steps in the mathematical formulation of this hypothesis as well as the experimental work performed in our laboratory and elsewhere concerning the proliferation and the volume of hepatocytes following partial hepatectomy does not support this hypothesis.

Electrical sizing of liver cell nuclei by the particle beam method. Mean volume, volume distribution and electrical resistance.

Electrical sizing of liver cell nuclei gives similar results as histological techniques for the mean volume, the volume distribution and the proportions of the different nuclear volume populations. The electrical method has, compared to histological technics, however, the advantage of higher rapidity and accuracy. Due to the good volume resolution of the improved electrical sizing method two populations of nuclei with different mean volumes can be distinguished in rat liver tissue besides di-, tetra- and octoploid cell nuclei. In addition to the volume distribution curves, the mean electrical resistance of isolated liver nuclei can be determined by the electrical sizing method. A newly developed micromehod provides enough cell nuclei for electrical sizing from only 10 mg liver tissue in a few minutes. This should enable the measurement of nuclear volume distribution curves of human biopsy material from the liver and gastrointestinal tract for diagnostic purposes on a larger scale.
