[An invariant of plasma viscosity].

Determination of "m" invariant cannot lead to an absolute measurement of plasmatic viscosity, because "m" increases with temperature. It allows however to compare data determined in various conditions.

[Physicochemical study of platelet aggregation by 3 polylysines].

The action of polylysines of various molecular weight on platelet behaviour is studied with the help of 3 techniques: photometric test, screen filtration pressure on PRP and electrophoretic mobility. Polylysines, which are polybasic substances, produce a platelet aggregation studied by photometry after a short period of latency. Aggregation, depending on the doses of poly-lysine and chiefly on the optic density, shows a "plateau" with the dose of 100 gamma/ml for poly-lysine L, of molecular weight 17000. The screen filtration pressure increases continuously in the presence of the polylysines studies. Finally, the platelet charge decreases. The results depend on the concentration of poly-lysine, and the optimal concentration which involves the more marked alterations is inversely proportional to the molecular weight of the polylysine studied.

[Pre-hospital resuscitation and transport of cardiac patients. Apropos of 107 cases of primary transport].

Report of 107 cases of primary transportation in ambulances especially equipped for coronary patients monitoring. The various delays of admission were studied and the complications occuring during transportation were analyzed, together with the various therapeutic methods applied. On the basis of this personal experience, and to attempt at diminishing the mortality at the acute stage of myocardial infarction, it was advised: --a careful information of the public, --a systematic training of the physicians, --a logic organization of emergency care. Only a coherent set up of fixed and mobile units might result in improvement of the prognosis of the first hours after myocardial infarction.
