Abstract

Procédé d'isolation d'un facteur endogène se liant sur le même site que les benzodiazépines, procédé caractérisé en ce qu'on broie un cerveau ou un cortex fraîchement prélevé ou congelé, on effectue une homogénéisation dans l'eau, on centrifuge la suspension obtenue, puis soit on effectue une dialyse du surnageant, soit on effectue une ultrafiltration du surnageant, soit on effectue une dialyse et une ultrafiltration du surnageant afin d'obtenir un facteur endogène d'un poids moléculaire inférieur à environ 1000 se liant sur le même site que les benzodiazépines.
