Figure 2. Histology of the ankle joint of the animals.

Figure 2

10× and 40× magnification of paraffin-embedded ankle sections stained with H&E, for the acute phase (day 5) and the chronic phase (day 21). The 40× magnification on day 5 shows leukocyte infiltration in the PG-PS-induced arthritis animals. Slides from the chronic phase in the PG-PS-induced arthritis animals showed fibrosis, pannus formation and severe leukocyte infiltration with more pronounced effects observed in the clopidogrel-treated animals.
