PAF-induced leukocyte adhesion in retinal and choroidal vessels. PAF (5 μg) was injected into the vitreous of Lewis rats; 2 h later, animals were perfused, and the vasculature was ConA stained. Subsequently, retinal and choroidal flat mounts were prepared, and number of firmly adhering leukocytes was quantified by counting. A) Representative micrographs of firmly adhering leukocytes (arrows) in retinal vessels. Higher magnification micrographs (bottom panels) show sections of the retinal veins. B) Numbers of leukocytes in retinal arteries. C) Numbers of leukocytes in retinal veins. D) Numbers of firmly adhering leukocytes in choroidal vessels. Bars are means ± se.
