Figure 4

Effects of the aqueous and methanol extracts of N. pobeguinii on the two phases of the pain induced by formalin. Data are expressed as the mean ± SEM of six animals per experimental group, compared by one-way analysis of variance followed by Tukey test; ^λ <0.001 means significantly different from the normal control group (nondiabetic); and ^c <0.001 means significantly different from the diabetic control group.
