Abstract

EL INVENTO MUESTRA LA PREPARACION EFICAZ DE LIPOSOMAS MARCADOS CON RADIONUCLIDOS Y PROTEINAS ENCAPSULADAS EN LIPOSOMA MARCADO CON RADIONUCLIDO. EN PARTICULAR, SE UTILIZA UNA MATERIA INACTIVA ISOTOPICA TC99M PARA MARCAR LIPOSOMAS PREFERIDOS O HEMOGLOBINA ENCAPSULADA EN LIPOSOMAS. LOS LIPOSOMAS MARCADOS CON TC99M Y LA HEMOGLOBINA MARCADA CON TC99M Y ENCAPSULADA EN LIPOSOMAS SON ALTAMENTE ESTABLES IN VITRO Y IN VIVO Y SON ADECUADOS PARA UNA SERIE DE USOS CLINICOS, INCLUYENDO ESTUDIO DE FORMACION DE IMAGENES DE BIODISTRIBUCION. EL INVENTO MUESTRA TAMBIEN UN METODO PARA MARCAR NEUTROFILOS UTILIZANDO LIPOSOMAS MARCADOS CON TECNECIO 99M O HEMOGLOBINA ENCAPSULADA EN LIPOSOMAS. SE MUESTRA ASIMISMO UN EQUIPO MEDICO UTIL PARA LA PREPARACION CONVENIENTE DE LIPOSOMAS MARCADOS CON TC99M O HEMOGLOBINA ENCAPSULADA EN LIPOSOMAS PARA USO CLINICO.
