Enrollment: 12
Study Start Date: October 2007
Study Completion Date: March 2008
Primary Completion Date: March 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Rosiglitazone; 8mg tablet once a day for 14 days
Drug: Rosiglitazone

Detailed Description:
The primary aim of the study is to examine the effect of rosiglitazone (Avandia) on gene regulation in colonic epithelium in the absence of pathologic acute and chronic intestinal inflammation. The secondary aims are to determine the effect of rosiglitazone (Avandia) therapy on T cell activation and cytokine expression in the absence of pathologic acute and chronic intestinal inflammation.
