Another study carried out by Liu et al. [117] in colitis model rabbits disclosed the activity of colon inflammation via a scintigraphy probe of 99 mTc-labeled scFv-VCAM-1 (vascular cell adhesion molecule-1) as a molecular image and generated a potential scheme for diagnosis of inflammatory bowel disease and immunohistochemistry analysis of inflammation. This evidence concerns the gene VCAM1 and colitis.
