Administration of the opioid agonist, morphine (1 and 10 mg X kg-1), resulted in significant, dose-dependent increases in the ingestive responses of food-deprived slugs, Limax maximus, and in the initiation of feeding in satiated animals. These effects could be blocked by the opiate antagonist, naloxone (1 mg kg-1), with naloxone by itself causing a significant decrease in the feeding of food-deprived slugs. These results suggest that opiates are involved in the control of the feeding behavior of Limax.
给饥饿的大蛞蝓（Limax maximus）注射阿片类激动剂吗啡（1毫克/千克和10毫克/千克），会导致其摄食反应显著增加，且呈剂量依赖性，同时也会使饱腹动物开始进食。这些作用可被阿片拮抗剂纳洛酮（1毫克/千克）阻断，而纳洛酮本身会使饥饿的大蛞蝓的进食量显著减少。这些结果表明，阿片类物质参与了大蛞蝓摄食行为的调控。
