Figure 3.
Myeloperoxidase (MPO) activity in gastric mucosa in Helicobacter pylori (HP) and/or aspirin (Asp) exposed gerbils. HP and/or Asp induced gastric mucosal injury was produced as described for fig 1 ▶. MPO activity in the gastric mucosa was determined by a modification of the method of Krawisz and colleagues.22 Values are mean (SEM) for six gerbils. *p<0.05 compared with control gerbils with neither HP infection nor Asp administration; ††p<0.01 compared with gerbils with HP infection or treatment with Asp alone.
