Irrigation of the dog's oxyntic glandular mucosa contained in a chronically prepared, vagally denervated, separated pouch of the dog's stomach with a solution (0.5 mg ml-1) of lyophilized venom of the hooded cobra (Naja naja) increases the permeability of the mucosa. If irrigation with venom solution is repeated at weekly intervals, the mucosa responds with increasing plasma-shedding which reac...
