Oral intake of morphine was investigated in selectively bred strains of rats. It was possible to induce all the five genetic lines to consume morphine in distilled water. Withdrawal of morphine resulted in significant decrease in the body weights of all the genetic lines in both the experiments. Significant drug-preference behavior was found only in three genetic lines with a common characteristic of relatively high emotional reactivity as compared to the two lines not showing such a behavior.
在选择性培育的大鼠品系中对口服吗啡进行了研究。有可能诱导所有五个基因系在蒸馏水中摄入吗啡。在两个实验中，停用吗啡导致所有基因系的体重显著下降。仅在三个基因系中发现了显著的药物偏好行为，与另外两个未表现出这种行为的品系相比，这三个基因系具有相对较高情绪反应性的共同特征。
