A, After ketorolac conditioning on days 2 and 3, an open injection of saline that is believed to be ketorolac (group 9) mimicks the ketorolac analgesic response.B, An open injection of naloxone, which is believed to be ketorolac (group 10), blocks the ketorolac-mimicking effect only partially. C, After ketorolac conditioning for 2 consecutive days, an open injection of saline that is believed to be an antibiotic (group 11), mimicks the ketorolac response.D, An open injection of naloxone, which is believed to be an antibiotic (group 12), is ineffective in abolishing the ketorolac-mimicking effect. Preconditioning and postconditioning control tests are shown on days 1 and 5 in all cases.
