Effect of Intravenous Lidocaine on Inflammatory and Apoptotic Response of Ischemia-Reperfusion Injury in Pigs Undergoing Lung Resection Surgery

Figure 1

Immunohistochemical detection of CD68, MCP-1, Bcl-2, and caspase-9 in lung biopsies. Samples were collected 60 minutes after reperfusion. Area of peripheral lung parenchyma consisting mostly of well-preserved alveolar wall. Strong nuclear or cytoplasmic staining macrophages or pneumocytes are identified. Images captured with 40x magnification objective (the mark scale corresponds to 30 μm).
