GU generally refers to ulcer lesions in thegastric mucosa. The main factors that cause GU are Helicobacter pylori and nonsteroidal anti-inflammatory drugs(NSAIDs). Probiotics have been studied for many years with the effects ongastrointestinal health. Therefore, we first screened complex probiotics forthe effects on reducing the NSAIDs-induced GU. 8-week-old ICR male mice weredivided into a normal control group, a negative control group, a positivecontrol group (10 mg/kg Omeprazole), and 8 groups of complex lactic acidbacteria (20.4 mg/kg/day). Except for the normal control group, mice were fedwith probiotics or saline for 29 days, then 10 consecutive days with additionof 500 mg/bw/day Aspirin to induce GU. On the 40th day, mice were sacrificedfor GU analysis. In the analysis of GU area,ulcer index, ulcer curative ratio, and pathological score, the combination of Lactobacillus plantarum GKD7 and Pediococcus acidilactici GKA4 was the most significant improvement.Therefore, complex strains GKD7/GKA4 would be further separated as a singlestrain for the mechanism studying on gastric protection.展开更多
