Abstract
Gastric injury is mainly described by inflammation of the gastric epithelium. Recently, our group of work demonstrated that Prosthechea karwinskii leaves extract induces both an in vitro antioxidative action and an in vivo gastroprotective effect in a rat. However, the molecules involved in the gastroprotective action by Prosthechea karwinskii are not known. Thus, the aim of this study is to determine whether Prosthechea karwinskii extract modifies anti-inflammatory and antioxidative biomarkers in an in vivo rat model of indomethacin-induced gastric injury. Rats were orally administered with indomethacin and Prosthechea karwinskii leaf extract. Our results suggest that the gastroprotective effect of Prosthechea karwinskii leaf extract is related to the reduction in leukocyte infiltration and antioxidative action in a model of indomethacin-induced gastric injury. Further studies are warranted to investigate the role of the compounds identified in the gastroprotective action of Prosthechea karwinskii leaves extract.
