After 3-hour exposure to HCl (pH 5.8) (brown bar) the mucosal sac did not release any more H2O2 into the surrounding supernatant than did nonacidified mucosa (green bar). In contrast, mucosa from animals with in-vivo–induced esophagitis (blue bar) released a significantly higher concentration of H2O2 into the supernatant. Values are mean + SEM, for three animals.
