Dexmedetomidine Alleviates Lung Oxidative Stress Injury Induced by Ischemia-Reperfusion in Diabetic Rats via the Nrf2-Sulfiredoxin1 Pathway

Figure 7

Alveolar epithelial cell apoptosis was demonstrated by TUNEL staining (original magnification, ×40). TUNEL-positive cells were observed under a light microscope and identified by brown-stained nuclei (shown with arrows). TUNEL: terminal deoxynucleotidyl transferase dUTP nick end-labeling; (a) CS group; (b) DS group; (c) CIR group; (d) DIR group; (e) DIRD group; (f) apoptosis index (). In the DIRD group, the 3 μg/kg of DEX was used. vs. the CS group; ^# vs. the DS group; ^△ vs. the CIR group; ^§ vs. the DIR group.
