title: Modulation of gastric mucosal mast cell population: role of vestibulo cerebellar lesion.
abstract: Posterior cerebellar lesion induced severe focal inflammatory ulcers at the stomach associated with extensive damage of the surface epithelial cells, leading to focal necrotic ulcers. The ulcer index increased maximally and progressively between day 7 and day 14 after lesion. The total mucosal mast cell and degranulated mucosal mast cell increased maximally on day 7 and progressively declined from day 14 to day 21. Gastric histamine content was also significantly increased on day 7 and 14. A significant reduction in mucous content (total CHO:P) was observed within 7-28 days after lesion. The results suggest that the gastric mucosal mast cells play an important role in ulcerogenesis induced by cerebellar lesion.
