Abstract :
The aim was to evaluate the effect of irradiation on cerebral microvascular permeability and cell adhesion. A cranial window was implanted in anesthetized male Sprague-Dawley rats to visualize the cerebral subpial vessels. Intravital fluorescence microscopy was used to obtain the fluorescent images of cerebral microvessels after i.v injection of FITC-dextran and rhodamine to measure vascular permeability and leukocyte adhesion, respectively. Permeability was determined by measurement of relative fluorescent intensity inside and outside of venules at specific time points after irradiation
