The invention provides for a method for the administration of a nucleic acid substance to the cells of an animal, a plant or a micro-organism the method being characterised in that the nucleic acid substance is formulated with an administration medium which comprises a solution of nitrous oxide gas in a physiologically acceptable carrier solvent for the gas and which administration medium includes at least one fatty acid or ester or other suitable derivative thereof selected from the group consisting of oleic acid, linoleic acid, alpha-linoelic acid, gamma-linolenic acid, arachidonic acid, eicosapentaenoic acid [C20: 5φ3], decosahexaenoic acid [C22: 6φ3], ricinoleic acid and derivatives thereof selected from the group consisting of the C1 to C6 alkyl esters thereof, the glycerol-polyethylene glycol esters thereof and the reaction product of hydrogenated natural oils composed largely of ricinoleic acid based oils, such as castor oil, with ethylene oxide. |
