Abstract

SE PRESENTAN SUSPENSIONES INYECTABLES DE MICROBURBUJAS LLENAS DE GAS, EN UN LIQUIDO PORTADOR ACUOSO, QUE SE USA COMO AGENTE DE CONTRASTE EN ECOGRAFIA ULTRASONICA. LAS SUSPENSIONES COMPRENDEN COMPUESTOS ANFIPATICOS DE LOS QUE AL MENOS UNO PUEDE SER UN FOSFOLIPIDO LAMINARIZADO COMO UN ESTABILIZADOR DE LAS MICROBURBUJAS, CONTRA EL COLAPSO CON TIEMPO Y PRESION. LA CONCENTRACION DE FOSFOLIPIDOS EN EL LIQUIDO PORTADOR ESTA POR DEBAJO DE 0''01% POR PESO, PERO ES AL MENOS IGUAL, O SUPERIOR, A LA QUE SE PRESENTAN AISLADAMENTE MOLECULAS FOSFOLIPIDAS EN EL ACOPLAMIENTO LIQUIDOMICROBURBUJAS DE GAS. TAMBIEN SE PRESENTA UNA PREPARACION DE LAS SUSPENSIONES ESTABLES DE MICROBURBUJAS LLENAS DE AIRE O GAS.
