Laser illumination enhances blood vessel permeability. (A) Representative images showing blood vessel leakage induced by laser. Blood vessels were marked by FITC-dextran IV injected, after which the dorsal skin of the mice was treated by different lasers and examined under an intravital confocal microscope within 30 min. (B) Representative histological examination of laser-treated skins. (C) Alterations of blood vessels induced by lasers. Bar=100 μm in A and B or 10 μm in C. Arrows indicate blood vessels. n=5.
