Recent data of study H2S in gastrointestinal tract has proven its potent cytoprotection on mucosal defense among acid-related diseases in the gut. The aim was to evaluate the effects of H2S-releasing aspirin derivative (ATB-340) on esophageal and gastric mucosa compromised by stress injury. Rats were treated with vehicle (control), aspirin (10 mg/kg), ATB-340 (17.5 mg/kg) single or 9 days duration, with or without induction of stress injury. Esophageal mucosa, gastric mucosa were estimated by histopathological damage scoring. Serological levels of VCAM-1, IL-6 by ELISA. ATB-340 treatment resulted in protective effect and lower grade of damage score in esophageal mucosa and gastric mucosa lesions vs effect of aspirin in single or 9 days applications. The serum levels of VCAM, IL-6 in rats who were aspirin-treated and subjected to stress-injury were higher than those in control animals. Treatment with ATB-340 produced an anti-inflammatory effect by decreasing VCAM and IL-6 vs aspirin. Cytoprotective effect of ATB-340 on esophageal mucosa and gastric mucosa was modulated by inhibi­ting inflammation and improving endothelial functions
