Vitamin D₃ Protects Mice from Diquat-Induced Oxidative Stress through the NF-κB/Nrf2/HO-1 Signaling Pathway

Figure 7

Effects of VitD₃ on inflammatory infiltration of macrophages in the jejunum and cell apoptotic status in the jejunum. (a) Immunohistochemistry staining of macrophages (F4/80) in the jejunum tissue. (b) TUNEL staining of the jejunum tissue. All images were viewed at the magnification of 100x through a microscope. (c) Macrophage invasion index, which was calculated through collecting the integrated optical density (Image-Pro software) based on the positive reaction cells of at least six slices, and the average values were calculated and compared with each group. (d) Cell apoptotic index, which was calculated through collecting the integrated optical density (Image-Pro software) based on the positive reaction cells of at least six slices, and the average values were calculated and compared with each group. All data were presented as (). , .
