PGP9.5 expression in the Control, DM, DM + A and DM + B groups, as determined via immunohistochemical analysis. Nuclei and PGP9.5 were labeled as blue and brown, respectively. A rat model of DM was established using an intraperitoneal injection of streptozotocin. The rats in the Control group were given an equal volume of citric acid solvent. Magnification, ×200. *P<0.05 vs. Control; #P<0.05 vs. DM. DM, diabetes mellitus model; DM + A, diabetic rats treated with 5 µg/kg prucalopride; DM + B, diabetic rats treated with 10 µg/kg prucalopride; PGP9.5, ubiquitin thiolesterase.
