Granted: 2005-01-25
Abstract: L'appareil comprend une enceinte de séchage (10), des conduits d'admission et d'évacuation (11, 12) à extrémités ouvertes communiquant avec l'enceinte, et des installations d'acheminement (13, 14, 15) servant à acheminer les matériaux à sécher dans le conduit d'admission, à travers l'enceinte et dans le conduit d'évacuation. On génère de la vapeur surchauffée dans l'enceinte à partir de l'humidité du matériau (19) en cours de séchage en faisant circuler le gaz initial dans l'enceinte entre une source de chaleur (23) et le matériau, et/ou en injectant dans l'enceinte la vapeur surchauffée provenant d'une source externe. Le conduit d'admission (11) et le conduit d'évacuation (12) s'étendent tous les deux vers le bas à partir de l'enceinte (10) et un conduit d'aération (22) venant de l'enceinte possède un orifice d'évacuation (26) situé normalement à mi-chemin le long des deux conduits. Lors de l'utilisation, la vapeur surchauffée tendant à descendre le long des conduits rencontre l'air extérieur tendant à monter et forme dans chaque conduit une couche de stratification présentant une différence de température et de densité (21). Ces couches font barrière à la fuite de la vapeur de l'enceinte alors qu'en même temps elles permettent le libre acheminement de matériaux dans les conduits et vers et à partir de l'enceinte (10).

Abstract: Defensis are microbicidal, numoricidal cytotoxic protein componements of animal host defense systems. They can be entrapped in liposomes containing release-inhibiting lipid such that the defensins are neutralized, and their release from the liposomes is inhibited; however, the defensins remain effective when exposed to endocytosed material in endocytic vesicles. Liposomal defensin formulations are administered to animals for the treatment or prevention of microbial infections, for the treatment of cancers and for the treatment of disorders characterized by a deficiency of protein-mediated cytotoxic activity in cytiolasmic granules.
