Abstract
The terrestrial snail Cepaea nemoralis, when placed on a 40 degrees C hot plate, lifts the anterior portion of its foot. The latency of this response is influenced by morphine and by naloxone in a dose-dependent and time-dependent manner. Morphine increases the time taken to respond, whereas naloxone reduces it. Furthermore, naloxone abolishes the effect of morphine. These results indicate that an opiate system may have a role in this behavior, which resembles that reported in vertebrates.
摘要
将陆生蜗牛黄斑蜗牛置于40摄氏度的热板上时，它会抬起足部的前部。这种反应的潜伏期受到吗啡和纳洛酮的剂量依赖性和时间依赖性影响。吗啡会增加反应所需的时间，而纳洛酮则会减少反应时间。此外，纳洛酮会消除吗啡的作用。这些结果表明，阿片系统可能在这种行为中发挥作用，这种行为与在脊椎动物中报道的行为相似。
