Abstract
Background: Gastric ulcer is commonly affected by several causes, including stress. This work examined the gastroprotective effects of ellagic acid (EA), in stress-induced gastric ulcers in Wistar rats.
Methods: Forty male Wistar rats were categorized into five groups: a normal control group, a stress-induced ulcer group, and three groups receiving EA treatment (5 mg, 10 mg, and 20 mg). Gastric ulcers were elicited using a water immersion stress model. Macroscopic and histological assessments, together with biochemical immunohistochemical studies were performed.
Results: EA therapy markedly decreased ulcer scores and indices in a dose-dependent manner. EA decreased TNF-α, IL-1β and MDA and augmented PGE1 and GSH. Histopathological assessments verified the results. The immunohistochemical analysis revealed increased Nrf2 and HO-1 levels and decreased NF-κB and COX-2 levels in the EA-treated groups.
Conclusion: EA demonstrates gastroprotective properties against stress-induced gastric ulcers via its anti-inflammatory and antioxidant mechanisms in a dose-dependent manner.
期刊介绍:
Archives of Physiology and Biochemistry: The Journal of Metabolic Diseases is an international peer-reviewed journal which has been relaunched to meet the increasing demand for integrated publication on molecular, biochemical and cellular aspects of metabolic diseases, as well as clinical and therapeutic strategies for their treatment. It publishes full-length original articles, rapid papers, reviews and mini-reviews on selected topics. It is the overall goal of the journal to disseminate novel approaches to an improved understanding of major metabolic disorders.
The scope encompasses all topics related to the molecular and cellular pathophysiology of metabolic diseases like obesity, type 2 diabetes and the metabolic syndrome, and their associated complications.
Clinical studies are considered as an integral part of the Journal and should be related to one of the following topics:
-Dysregulation of hormone receptors and signal transduction
-Contribution of gene variants and gene regulatory processes
-Impairment of intermediary metabolism at the cellular level
-Secretion and metabolism of peptides and other factors that mediate cellular crosstalk
-Therapeutic strategies for managing metabolic diseases
Special issues dedicated to topics in the field will be published regularly.
