Increased gastric mucosal perfusion in cirrhotic patients with portal hypertensive gastropathy.

abstract：BACKGROUND & AIMS:Epithelial cells of the small intestine migrate to the tip of the villus at which they are shed. It is not understood how the intestinal barrier is maintained during this high cell turnover. The aim of this study was to use high-resolution in vivo light microscopy to investigate the mechanism of epith...
