Grape seed proanthocyanidin protects liver against ischemia/reperfusion injury by attenuating endoplasmic reticulum stress

Figure 4 Effects of grape seed proanthocyanidin on hepatocytic apoptosis. TUNEL staining was performed and 100 cells per field were counted in three fields (400 ×). A: Sham; B: Ischemia/reperfusion (IR); and C: IR with grape seed proanthocyanidin (GSP) treatment; D: Quantification of TUNEL staining; n = 8 each; ^bP < 0.01 vs IR.
