Figure 6.

Effect of antineutrophil serum (ANS) on erosion index and thiobarbituric acid reactive substances (TBARS) in the gastric mucosa after administration of aspirin (Asp) to uninfected or Helicobacter pylori (HP) infected gerbils. Asp (400 mg/kg) and 0.1 N HCl were administered orally to gerbils three weeks after inoculation with HP. ANS (15 ml/kg) was injected intraperitoneally 18 hours before administration of Asp. Control gerbils received intraperitoneal injection of normal rabbit serum. Values are mean (SEM) for six gerbils. *p<0.01 compared with normal gerbils given neither HP nor Asp; †p<0.05, ††p<0.01 compared with control gerbils treated with normal rabbit serum.
