The protective effects of Hericium Tablets on acute alcoholic gastric mucosal injury in rats and its mechanism / 中成药

ABSTRACT

AIM To explore the protective effects of Hericium Tablets on the injury of gastric mucosa and to investigate its possible mechanism.METHODS The rats were orally given doses of Hericium Tablets (0.25,0.5,1.0 g/kg) once a day for seven days.One hour after the last doses,the rats were orally given a dose of anhydrous ethanol (5 mL/kg).In one hour,the degree of gastric mucosal injury and pathological changes were observed.Gastric juice pH and pepsin activity were detected by absorbing the gastric juice.The contents of amino hexose,PGE2 and IL-1β were detected by scraping gastric mucosa.RESULTS Hericium Tablets can obviously alleviate the damage degree of gastric mucosa,reduce the gastric mucosal hyperemia,bleeding,edema and necrosis,as well as against the decrease of pepsin activity in gastric juice,and the decrease of the content of amino hexose in gastric mucosal layer was inhibited,but there was no significant effect on the contents of PGE2 and IL-1 β and the increasement of pH value of gastric juice.CONCLUSION The effects of Hericium Tablets on gastric mucosal injury are obvious,and its mechanism is related to the decrease of the contents of gastric mucosa.
