Comparison of kinetics of transient and sustained currents evoked by α,β-meATP in DRG neurons from control limbs and limbs with femoral artery occlusion

	Transient			Sustained
Group	Tr, ms	τ1d, ms	τ2d, ms	Tr, ms	τd, ms
Control	6.4 ± 0.8	42.3 ± 5.4	298.2 ± 69.0	68.6 ± 8.5	2,582.7 ± 374.6
Occlusion	6.2 ± 0.7	40.2 ± 6.1	326.1 ± 77.3	71.7 ± 10.0	2,791.0 ± 478.3

Data are means ± SE for rise time (T_r) and decay time constants (τ_d); n = no. of neurons. Kinetics were measured in control group dorsal root ganglion (DRG) neurons with transient currents (n = 30) and with sustained currents (n = 29) and in occlusion group neurons with transient currents (n = 52) and with sustained currents (n = 41) evoked by α,β-methylene ATP (α,β-meATP). No significant differences were seen in T_r and τ_d values between the control and occlusion groups (P > 0.05).
