Figure 4

The bar graphs illustrate the population relative mechanical threshold before and after femoral vein injection of buffered isotonic saline (top, n=10) or 50 mg/kg MSG (bottom, n=10). Overall, there was no significant alteration in relative mechanical threshold over time after injection of saline. Following the injection of MSG, there was a significant (*) decrease in mechanical threshold from pre-injection baseline values during the first 5 min epoch. There were no significant sex-related differences in relative mechanical threshold in the saline or glutamate groups and no significant interactions between time and sex. * P < 0.05 one-way repeated measures ANOVA and post-hoc Holm-Sidak method compared with baseline.
