Figure 2. Effect of systemic tail vein administration of TL02-59 on Coll IV microinjection–induced thalamic pain development.

Figure 2

TL02-59 (15 mg/kg) or vehicle was given 30 minutes before Coll IV or saline microinjection and once daily post–Coll IV or saline microinjection. Effect of systemic preadministration of TL02-59 or vehicle on paw withdrawal frequencies to 0.07 g (A and E) and 0.4 g (B and F) von Frey filaments and paw withdrawal latencies to heat (C and G) and cold (D) stimuli on days 1 and 3 after thalamic microinjection of Coll IV or saline on the contralateral (A–D) and ipsilateral (E–G) sides. n = 8 mice/group. Two-way ANOVA with repeated measures followed by post hoc Tukey’s test. **P < 0.01 versus the corresponding baseline (day –1). ##P < 0.01 versus the Coll IV plus vehicle group at the corresponding days.
