Figure 1.

Effect of intra-articular carrageenan on the knee joint incapacitation (A), oedema (B) and neutrophil infiltration (C). λ-Carrageenan (2%, 25 µL) or saline (control group) was injected into the right knee of rats. Knee joint incapacitation, oedema and myeloperoxidase activity were measured at various times after carrageenan administration. Data are expressed as the mean ± SEM of 12 experiments. *P < 0.05 significantly different from the respective control value (one-way anova followed by Dunnett's post-test).
