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

Figure 9

Protein expression of caspase-9 in lung tissues by immunohistochemistry (original magnification, ×40). Caspase-9-positive cells were observed under a light microscope and identified by brown-stained nuclei. (a) CS group; (b) DS group; (c) CIR group; (d) DIR group; (e) DIRD group; (f) immunohistochemical scores (IHS) (). 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.
