title: Anti-ulcer and membrane stabilizing actions of zinc acexamate.
abstract: The effects of zinc acexamate on stress and reserpine ulcers as well as on gastric mast cells degranulation and membrane stability were evaluated in the rat. Zinc acexamate (100 mg/kg) has demonstrated an inhibitory effect on cold-restraint stress and reserpine-induced ulcer in a dose-dependent manner. Pretreatment of rats, prior to cold restraint stress, reduced gastric mast cell degranulation. Zinc acexamate (10(-4) M) inhibits Triton X-100 release of beta-glucuronidase in isolated hepatic lysosomes. These observations suggest that ulcer protective actions of zinc acexamate may be exerted in part through enhancing gastric mucosal resistance by stabilizing biological membrane integrity.
