A new study (http://www.sciencedaily.com/releases/2005/09/050930082424.htm) shows that beta gluan can penetrate the skin. According to the article, beta glucan is a molecule in Oat once though too large to get "in" and work its magic (e.g., promote wound healing, reduce fine lines wrinkles). The article discuss the cosmetic aspects of the research and briefly mentions that beta glucan also has potential as a method of transdermal (through the skin) drug delivery.

Scientists appear to be correct that beta glucan is too large to get into cells, but it is able to squeeze its way deep into the fatty matrix between cells.

As a vehicle for drug delivery, I'm guessing scientists would pack the beta glutan with molecules too large to be absorbed through the skin, let the oat glucan work its way down, and then release whatever helpful molecule is contained within it.

For curing SCI, the molecule would still have to cross the blood brain barrier, but if this does work out, it would be a good step forward in transdermal delivery.

Just some random musings...
