mainly neutrophils (arrows) at 24 h after endotoxin injection (LPS
24h). E: Intact mast cell (curved arrow) in the ciliary process
and mononuclear phagocytic cells (open arrows) adhered to the iris
surface (F) at 48 h post-injection (LPS 48h). G, H:
Ciliary bodies of animals pretreated with secretagogue c48/80 before
EIU (c48/80 + LPS 24h). Absence of mast cells and very few
transmigrated inflammatory cells (arrow). V: blood vessel. Bars, 10 μm.
