3.1.2-Gpx
Similar results are encountered for H-score as seen in the SOD group. Gpx activity increased in the PPI group (p<0.002), with less activity observed in the Ra group (p<0.002) (Figure 1). When glutathione peroxidase staining is investigated on immunohistochemical pictures, strong immunoreactivity was observed in the PPI and Ra groups, with moderate intensity staining observed in the control group (Figure 2-B). PPIs were concluded to be more effective on glutathione peroxidase activity in lung compared to H2 receptor blockers.
