Figure 3

Intradermal co-administration of TNP-ATP, but not TNP-AMP, with 5% formalin attenuated acute nociceptive paw flinching in the rat (n=6 per dose group). Phase I represents cumulative acute nociceptive responses occurring 15 min immediately following intradermal administration (F(2,27)=5.15, P<0.05). Phase II represents cumulative nociceptive responses recorded for a 20-min period beginning 30 min post formalin injection (F(2,27)=6.97, P<0.05). Values represent mean±s.e.mean, *P<0.05 as compared to vehicle-treated rats.
