This is due to the infiltrative presence of tumor cells in the surrounding brain lessening fluorescence intensity to a pink color. Waiting at least 3 h prior to the initiation of skin incision is best. Focusing on this, we found that 5-ALA has a strong antioxidant effect the effect of eliminating ROS by inducing HO-1 and producing bilirubin and carbon monoxide.
