[Biorheology: problems and results in medicine].

After a short explanation of the topic and a methodological introduction, several recent biorheological findings are presented and discussed. Intrinsic viscosity measurements with lipoproteins show, that a certain type associates strongly in presence of Ca ions thus representing a risk factor for infarction. A rheological theory of rheumatic deterioration of knee joint synovial fluid is presented and suggested as a diagnostic aid. Finally, recent results in blood rheology are reported and their bearing on circulation problems and arterial obstructive conditions discussed.
