Fig. 3From: Effects of calcitriol (1, 25-dihydroxy-vitamin D3) on the inflammatory response induced by H9N2 influenza virus infection in human lung A549 epithelial cells and in miceChanges in lung histopathology of calcitriol treated mice. Lung samples were harvested from calicitriol (5 mg/kg) treated H9N2 infected mice on days 2 (A), 4 (B), 6 (C), and 8 (D) post infection. Lung tissues were harvested from untreated H9N2 infected mice on days 2 (E), 4 (F), 6 (G), and 8 (H) post-infection. Original magnification 100 × Back to article page
