Abstract

Spasmolytic polypeptide (SP) is a member of the trefoil peptide family; gut peptides that participate in the protection and repair of the gastric mucosa. Previous studies have failed to agree on the mode of action of human SP (hSP). We investigated the effect of orally administered human SP on the protection and repair of rat gastric mucosa in an established in vivo model of damage induced by the non-steroidal anti-inflammatory drug aspirin (ASA). The integrity of the gastric mucosa was quantified in four ways: the temporal change in transmucosal potential difference (PD), area of macroscopic damage by planimetry, relative area of microscopic damage by histological morphometry, and the numbe..
