- One of the main motivations for developing the theory of interpolation was to apply it to the theory of partial differential equations (PDEs). Nowadays interpolation theory has been developed in an almost unbelievable way {see the bibliography of Maligranda [Interpolation of Operators and Applications (1926-1990), 2nd ed. (Luleå University, Luleå, 1993), p. 154]}. In this article some model examples are presented which display how powerful this theory is when dealing with PDEs. One main aim is to point out when it suffices to use classical interpolation theory and also to give concrete examples of situations when nonlinear interpolation theory has to be applied. Some historical remarks are also included and the relations to similar results are pointed out

- Abstract An international, multi-centre trial was carried out to test the haemorheological effects of ketanserin, a serotonin antagonist, after treatment of intermittent claudicants for 1 year. Haematological indices, whole blood viscosity, plasma viscosity and red cell and white cell filterabi1ity were measured using standardised techniques. Even so, inter-laboratory variability, and intra-laboratory changes in control values in some centres over the 1 year period proved to be major obstacles. The pooled data showed no evidence of haemorheological changes, although data from the single largest centre indicated slightly lowered haematocrit and blood and plasma viscosity. Any rheological effects of serotonin antagonists in intermittent claudicants are probably small and unlikely to be the main source of any clinical efficacy. In general, it would appear that standardisation and monitoring of laboratory techniques must be strictly carried out if there is to be any hope of successfully carrying out multi-centre haemorheological trials. .
