Summary
This study evaluates the effect of acute administration of oral prednisone in white blood cells counts and glucose tolerance and the relationship of these measures with changes in gene expression in healthy volunteers. White blood cells counts, glucose tolerance and gene expression will be study before and after prednisone administration.
