Disposition of liposomal gentamicin following intrabronchial administration in rabbits.

Use of liposomes as carriers of gentamicin for intrabronchial pulmonary delivery was investigated in rabbits. Gentamicin, in isotonic glutamic acid buffer, pH 4.5, was encapsulated in multilamellar vesicles (MLVs) and administered intrabronchially.

An automated micromethod for detection of lytic antimycobacterial antibodies by immune lysis of liposomes sensitized to tuberculin.

Calcein was concentrated inside multilamellar liposomes (MLV) by encapsulation through an osmotic gradient in order to increase its quenching. Immune lysis of these MLV sensitized to PPD by direct encapsulation or by exposure to preformed vesicles was studied in the presence of rabbit anti-BCG serum and of a non-immune rabbit serum as a source of complement, successively added in the wells of a microplate to a final volume of 0.1 ml.
