Figure 1

The establishment of a rat acute gout arthritis model and the characterization of the pain and inflammation properties. (a) Representative photos of rat ankle treated with either PBS (left panel, Veh group) or MSU (right panel, 1.25 mg/ankle, MSU group) via intra-articular (i.a.) injection. Black arrow indicates the injected ankle. (b) Representative microscopic photos of ankle synovial tissue sections from rats treated with vehicle or MSU. Whole sections are stained with hematoxylin/eosin. The scale bar indicates 50 μm. (c–f) Time course of Δ increase of ankle thickness (c), ongoing pain score (d), 50% paw withdraw threshold (PWT, e), and paw withdraw latency (PWL, f) of Veh (in black) and MSU (in red) group rats. and versus Veh group. –8 rats/group.
