OBJECTIVE: To explore the mechanisms of muscovite gastric mucosal protective effect.
METHOD: Rat model of chronic gastritis were used. After gastric mucosal injury was induced, the rats were divided into 6 groups and were treated with different drugs. 2 weeks later, the tissue and blood samples were obtained and measured.
RESULT: The general conditions, the observations under macroscopy, microscope and electron microscope of the middle and high dose of muscovite groups resembled those of the normal group. Their PH levels were higher than those of the model group, and the rates of intestinal metaplasia were lower, but the PGE2 level of the middle dose of muscovite group was the highest.
CONCLUSION: Muscovite can be adsorbed on the surface of the gastric mucosa. It has gastric mucosal protective effect by improving excretion of mucus and synthesis of PGE2 in gastric mucosa, restraining gastric acid, reversing of intestinal metaplasia and decreasing inflammation cells.
