In this study, we have investigated the specific binding proteins of Zinc-l-carnosine (Polaprezinc) using Polaprezinc-affinity column chromatography in vitro. A protein having a 70-kDa molecular mass was eluted by the linear gradient of 0-1.0 mM Polaprezinc from the affinity column and the protein w

AIMS: Polaprezinc (PZ), which consists of l-carnosine and zinc, is widely used to treat gastric ulcers. We compared the effects of PZ with those of rebamipide (RM) on the expression of inflammatory cytokines, antioxidants, growth factors, and heat shock proteins (HSP) in a rat model.MAIN METHODS: Se
