Objectives : Gastric lesions affect many people around the world and their development are results of the imbalance between destructive and protective factors in the gastric mucosa. Lycium chinense has been widely used as a traditional Korean medicine, it was recently reported that they have potent anti-inflammatory effects in chronic hepatitis models. Therefore, this study aimed to investigate the anti-inflammatory activity of Lycium chinense extract (LCE) on HCl-Ethanol induced gastric lesion mice.Methods : The ICR mice were divided randomly into five groups of six animals each. Group A was normal mice, and group B was treated orally with 0.5 ml 150 mM HCl-60% Ethanol. Mice in group C and D were pre-treatment of LCE (100 mg/kg and 200 mg/kg bodyweight, p.o before HCl/ethanol treatment) and group E was orally administered sucralfate (10 mg/kg).Results : 150mM HCl/60% ethanol-induced gastric mucosal injury mice were ameliorated mucosal damage upon histological evaluation by treatment of LCE. Pre-treatment of LCE attenuated reactive oxidative species (ROS) and produces peroxynitrite (ONOO-) in stomach tissues. As results of stomach protein analyses, LCE effectively reduce inflammatory-related factors such as cyclooxygenase-2 (COX-2), tumor necrosis factor alpha (TNF-α), inducible nitric oxide synthase (iNOS) and interleukin-6 (IL-6) in gastric lesion mice. In addition, nuclear factor kappa B (NF-κB) and inhibitor of phosphorylation of nuclear factor kappa B (p-IκB) were down-regulated in LCE-administrated gastric lesion mice.Conclusions : Our discovery supports that the therapeutic activity of LCE ameliorate the development of gastric lesion via suppressing the oxidative stress and gastric partial inflammation induced by 150 mM HCl/60% ethanol.
