The effects of pre-treatment with morphine (5 mg kg−1, s.c.) and naloxone (1.5 mg kg−1, s.c.) on i.a. (a) propofol- and (b) capsaicin-evoked EMG responses. *P<0.05, **P<0.01, saline vs morphine; #P<0.01; +P<0.05, morphine vs morphine + naloxone; $P<0.01, saline vs morphine + naloxone (n=6, Fisher's Protected LSD test).

The effects of arterial pre-treatment with capsazepine (20 μg) on i.a. (a) propofol- and (b) capsaicin-evoked EMG responses. **P<0.01 vs 1% DMSO (n=6, Fisher's Protected LSD test).

8. Fig 7
The effects of pre-treatment with indomethacin (INDM, 10 mg kg−1, i.p.) on i.a. (a) propofol- and (b) capsaicin-evoked EMG responses. Prostaglandin E2 (PGE2, 5 μg) was infused arterially 55 min after indomethacin treatment. **P<0.01 vs 0.5% TWEEN 80, indomethacin + prostaglandin E2 (n=5, Fisher's Protected LSD test).
