Compositions and methods for treating inflammation
Provided are electrokinetically-altered fluids (gas-enriched (e.g., oxygen-enriched) electrokinetic fluids) comprising an ionic aqueous solution of charge-stabilized oxygen-containing nanostructures in an amount sufficient to provide, upon contact with a cell, modulation of at least one of cellular membrane potential and cellular membrane conductivity, and therapeutic compositions and methods for using same in treating inflammation or at least one symptom thereof. The electrokinetically-altered fluid compositions and methods include electrokinetically-altered ionic aqueous fluids optionally in combination with other therapeutic agents. Particular aspects provide for regulating or modulating intracellular signal transduction associated with inflammatory responses by modulation of at least one of cellular membranes, membrane potential, membrane proteins such as membrane receptors, including but not limited to G-Protein Coupled Receptors (GPCR), and intercellular junctions (tight junctions, gap junctions, zona adherins and desmasomes). Other embodiments include particular routes of administration or formulations for the electrokinetically-generated fluids (electrokinetically-generated gas-enriched fluids and solutions) and therapeutic compositions.
1. A method for alleviating symptoms of asthma or chronic obstructive pulmonary diseases (COPD), comprising administering to a subject in need thereof a therapeutically effective amount of an oxygenated aqueous fluid comprising an ionic aqueous solution of charge-stabilized oxygen gas-containing nanobubbles having an average diameter of less than 100 nanometers sufficient for alleviating symptoms of asthma or COPD, said fluid comprising sodium chloride, said oxygenated fluid oxygenated to a level of at least about 40 ppm at atmospheric pressure.
2. The method of claim 1 , said oxygenated aqueous fluid comprising the ionic aqueous solution oxygenated to a level of at least about 50 ppm dissolved oxygen.
3. The method of claim 1 , wherein said administering comprises at least one of topical, inhalation, intranasal, oral and intravenous administration.
4. The method of claim 1 , wherein the symptoms are associated with asthma.
5. The method of claim 1 , wherein the symptoms are associated with COPD.
