Examination of cells that engulfed OVA-gold in the conjunctiva. Conjunctival samples were prepared as described in Figure 2
. Cells that engulfed OVA-gold were examined histologically by light (A
) and electron microscopy (B
). Gold particles were detected in the cytoplasma of cells in the conjunctiva (A
). C and R indicates conjunctiva and retina, respectively (A
). Gold particles were present in cytoplasms of oval-shaped cells and spindle-like-shaped cells (B
). Arrows indicate cells that engulfed gold particles.
