Abstract

RNA was isolated from mucosal tissue of the duodenum, jejunum, ileum and colon after perfusion. The gene expression profiles were measured using Affymetrix GeneChip(R) analysis. Prodrug valacyclovir permeability was 5-fold and 2-fold higher than the parent drug acyclovir in the jejunum and ileum, respectively.(omitted)
