Ethanol deliveries maintained fixed-ratio (FR) responding of three rhesus monkeys during daily 3-h sessions. At FR values of 8 or 16, ethanol concentration was varied in the sequence 0 (water), 8, 11.3, 16, 22.6 32, 8, and 0% (w/v). As the ethanol concentration increased, number of liquid deliveries decreased somewhat. Blood ethanol levels were usually greater than 200 mg% and occasionally greater than 300 mg%.
在每天3小时的实验过程中,给三只恒河猴提供乙醇,维持其固定比例(FR)反应。当固定比例值为8或16时,乙醇浓度按0(水)、8、11.3、16、22.6、32、8和0%(w/v)的顺序变化。随着乙醇浓度的增加,液体输送量略有减少。血液乙醇水平通常大于200mg%,偶尔大于300mg%。
