Le traité De Principe rédigé par Giovanni Pontano dans la seconde moitié du Quattrocento vise à éduquer le futur souverain, Alphonse II et à lui offrir tous les outils pour conforter sa légitimité contestée par les barons napolitains. La rhétorique de l'éloge, conjuguée au discours didactique, sert ici la construction d'un idéal de souverain, appuyé sur les modèles antiques mais aussi nourri de références contemporaines, l'humaniste proposant une véritable parénèse vers l'accession à la sagesse, qui repose sur l'acquisition d'une solide culture, condition sine qua non pour que se développent les vertus. Mais cet apprentissage demeure incomplet si le prince ne sait pas en outre se doter d'une persona destinée précisément à faire apparaître ses qualités. L'attention portée au souverain en représentation, exposée d'après les modèles de l'orateur et de l'acteur, ouvre la voix à une nouvelle conception de l'exercice du pouvoir.

ABSTRACT 1. The metabolism of suspensions of circulating leucocytes has been studied after intramuscular injection of a dose of 50 mg/kg of a corticosteroid (cortisone acetate). The suspensions were incubated under aerobic conditions in the presence of a glucose concentration of 5.6 mm. Glucose consumption, lactate production, and variations in intracellular glycogen concentration were measured. After the administration of the corticosteroid, the anabolic processes of granulocyte metabolism were reversibly stimulated. Glucose consumption and lactate production increased 12 hours after the injection, but tended to normalize after 24 hours. The glycogen content of the granulocytes was enhanced, and glycogen synthesis during the course of the incubation was greatly stimulated. The action of the administered corticosteroid is more prolonged in females than in males. The injection of the corticosteroid caused metabolic modifications which resemble in their modulations and in their chronological development those found in circulating granulocytes of guinea-pigs suffering from sterile peritonitis. These results suggest, therefore, that, in the case of acute inflammation, the glucocorticosteroids may play an important role in the regulation of the metabolism of the blood leucocytes.
