Effects of Lycium barbarum polysaccharides (LBP) and/or C-phycocyanin (CPC) on the levels of a cyclooxygenase-1 (COX-1), b cyclooxygenase-2 (COX-2), c prostaglandin E2 (PGE2), and d total nitrite and nitrate (NOx) in stomach tissue. N, standard powder diet; ASP, aspirin; LBP, aspirin + Lycium barbarum polysaccharides (LBP); CPC, aspirin + C-phycocyanin (CPC); MIX, aspirin + LBP + CPC. Data are mean ± SEM (n = 10–12 per group). Differences between the groups were determined by one-way ANOVA followed by Fisher’s least significant difference test. *p < 0.05 compared with the N group; #p < 0.05 compared with the ASP group
