Oxygen is removed or maintained in a sealed container by electrochemically reducing the oxygen to water using an enzymatic O2 scavenging system based on a laccase enzyme. Activation of the O2 scavenging system typically occurs by water (liquid or vapor) adsorption; in preferred embodiments, ascorbate and isoascorbate (and their corresponding acids) are especially advantageous for their dual role as reductant and hygroscopic agent. The capacity of the O2 scavenging system can be manipulated by altering the concentration of reductant that is included in the O2 scavenging composition. The O2 scavenging system can be prepared in a variety of formats (e.g., inks, labels, packets, liners, patches, caps, within the packaging material itself) and is readily produced by apparatuses conventionally used in the industry on a high speed continuous basis.

Early treatment for a degenerated disc includes identifying a non-ruptured, dehydrated disc. A hygroscopic agent is then selected. This agent should pull water towards itself and have a hygroscopic compound with a molecular weight of at least 400 Daltons. Additionally, it may be desirable to selected hygroscopic compounds that are anionic or electrically neutral.
