CRP is an acute inflammatory protein that is known to increase in inflammation and infections, and is primarily produced in the liver, smooth muscle cells, macrophages, endothelial cells, lymphocytes, and adipocytes.22 Plasma CRP levels may increase from 1 μg/mL to 500 μg/mL within 24- 72 hours in cases of inflammation, infection, trauma or cancer, which cause serious tissue damage.23,24 We showed that levels of WBCs and CRP increased due to posterolateral thoracotomy on post-op. This evidence concerns the gene CRP and infection.
