The blood-brain barrier (BBB) in one cerebral hemisphere of rabbit was damaged by the ipsilateral infusion of hypertonic (3 Molar) urea into the carotid artery. Using the indicator diffusion technique, the clearance of the glycine (by simple diffusion) and phenylalanine molecule (by facilitated diffusion) was enhanced in the urea infused cerebral hemisphere. The experimental methodology is a nondestructive and sensitive method for evaluating the integrity of the BBB.
