AIM: To investigate the effects of Clostridium butyricum (C. butyricum) on experimental gastric ulcers (GUs) induced by alcohol, restraint cold stress, or pyloric ligation in mice, respectively.
METHODS: One hundred and twenty mice were randomly allocated into three types of gastric ulcer models (n = 40 each), induced by alcohol, restraint cold stress, or pyloric ligation. In each GU model, 40 mice were allocated into four groups (n = 10 each): the sham control group; model group (GU induction without pretreatment); C. butyricum group (GU induction with C. butyricum pretreatment); and Omeprazole group (GU induction with Omeprazole pretreatment). The effects of C. butyricum were evaluated by examining the histological changes in the gastric mucosal erosion area, the activities of superoxide dismutase (SOD) and catalase (CAT), the level of malondialdehyde (MDA), and the contents of interleukin (IL)-1β, tumor necrosis factor (TNF)-α, leukotriene B4 (LTB4) and 6-keto-PGF-1α (degradation product of PGI2) in the gastric tissue.
RESULTS: Our data showed that C. butyricum significantly reduced the gastric mucosal injury area and ameliorated the pathological conditions of the gastric mucosa. C. butyricum not only minimized the decreases in activity of SOD and CAT, but also reduced the level of MDA in all three GU models used in this study. The accumulation of IL1-β, TNF-α and LBT4 decreased, while 6-keto-PGF-1α increased with pretreatment by C. butyricum in all three GU models.
CONCLUSION: Our data demonstrated the protective effects of pretreatment with C. butyricum on anti-oxidation and anti-inflammation in different types of GU models in mice. Further studies are needed to explore its potential clinical benefits.
Core tip: In this study, we reported that the probiotic Clostridium butyricum (C. butyricum) pretreatment obviously attenuated gastric mucosal lesions induced by different stimulations. The oxidative stress- and inflammation-related parameters detected in this study showed that anti-oxidation and anti-inflammation participate in the underlying mechanism of C. butyricum protective effect on gastric mucosa. Our findings provide a potential protective method for the gastric mucosa and a novel application for C. butyricum in the clinic.
