Mouse-killing behaviour in rats increased the nociceptive threshold for paw licking, as measured in the hot-plate test. This effect was prevented by the opiate antagonist naloxone, which, on the other hand, had no influence on mouse-killing behavior per se. It is concluded that opioid mechanisms may be involved in changes of nociceptive threshold associated with aggressive behavior.
在热板试验中，大鼠的杀鼠行为提高了舔爪的痛觉阈值。阿片类拮抗剂纳洛酮可阻止这种效应，而纳洛酮本身对杀鼠行为并无影响。由此得出结论，阿片类机制可能参与了与攻击行为相关的痛觉阈值变化。
