Figure 2From: A3 adenosine receptors and mitogen-activated protein kinases in lung injury following in vivo reperfusionRepresentative results of TUNEL staining. Alveolar parenchyma from left lower lobe: (a) Nonischemic (group i) and (b) ischemia/reperfusion injury (group ii). Note that there are more bright green cells in panel b than in panel a, indicating more apoptosis. TUNEL, TdT-mediated dUTP nick end labeling.Back to article page
