Description

Abstract Background Non-steroidal anti-inflammatory drugs such as aspirin are used for the treatment of cardiovascular disease. Chronic use of low-dose aspirin is associated with the occurrence of gastric ulcer. The aim of this study was to investigate the healing potential of Lycium barbarum polysaccharides (LBP) from Chinese Goji berry and C-phycocyanin (CPC) from Spirulina platensis on gastric ulcer in rats. Methods Male Sprague–Dawley rats were divided into five groups: normal, aspirin (700 mg/kg bw), LBP (aspirin + 100 mg/kg bw/d LBP), CPC (aspirin + 50 mg/kg bw/d CPC), and MIX (aspirin + 50 mg/kg bw/d LBP + 25 mg/kg bw/d CPC) groups. Gastric ulcer was developed by daily oral feeding of aspirin for 8 weeks. Treatments were given orally a week before ulcer induction for 9 weeks. Results The MIX group elevated gastric cyclooxygenase-1, prostaglandin E2, and total nitrite and nitrate levels by 139%, 86%, and 66%, respectively, compared with the aspirin group (p
