(L.) Lam. Fruit Accelerates Healing in Gastric Injury via the Regulation of the NF-B Pathway.

OBJECTIVE

The present study aimed at the anti-inflammatory and antioxidant effects of the extract of fruit (BGF) on the gastric injury.

MATERIALS AND METHODS

The chemical components in the extract of BGF were used in UPLC/Q-Orbitrap analysis. 60 SD rats were randomized into six groups: normal group (MC), ethanol-injured control group (EC), omeprazole group, and three groups with different doses (50, 100, and 200 mg/kg) of BGF. After continuous administration for seven days, the stomachs of rats were taken out to observe the pathological gastric tissue changes; inflammatory factors and oxidative stress markers in the stomach tissues were measured. Western blot (WB) analyses were conducted to explore the mechanism of BGF on gastric tissue and RAW 246.7 cells with excessive inflammation.

RESULTS

BGF enhanced gastric mucosal protection by improving the mucosal blood flow of the stomach and significantly decreased inflammatory factors and oxidative stress markers. Moreover, BGF significantly reduced the expression of p-NF-B p65. Consistently, BGF demonstrated similar effects on LPS-induced RAW 264.7 cells as it did in vivo.

CONCLUSION

BGF could accelerate the healing of gastric injury by exerting antioxidant and anti-inflammatory effects and maintaining mucosal integrity.
