N
• mice exhibit normal nociception prior to opioid infusion
• unlike in wild-type mice, mice exhibit decreased tail-withdrawal latencies demonstrating the abolishment of opioid analgesic responses to acute doses of morphine and oxymorphone
• infusion of morphine results in a decrease in tail withdrawal latency relative to baseline after 2 days unlike similarly treated wild-type mice that display an increase on the first two days and a decrease on days 4 through 7
• infusion of oxymorphone results in reduced tail withdrawal latency compared to baseline at 4 days unlike in similarly treated wild-type mice that exhibit an increase in latency within the first 4 days and a decrease on days 8 through 10
• NMDA receptor blockage with MK-801 does not reverse opioid hyperalgesia unlike in similarly treated wild-type mice
• unlike in wild-type mice, mice exhibit decreased tail-withdrawal latencies demonstrating the abolishment of opioid analgesic responses to acute doses of morphine and oxymorphone
• infusion of morphine results in a decrease in tail withdrawal latency relative to baseline after 2 days unlike similarly treated wild-type mice that display an increase on the first two days and a decrease on days 4 through 7
