Effects of single compared with pair housing on hypothalamic-pituitary-adrenal axis activity and low-dose heroin place conditioning in adult male Sprague-Dawley rats.

Whether social isolation of adult rats under standard laboratory conditions produces significant long-term alterations in behavior and physiology is unclear. In the present study, male Sprague-Dawley rats were singly or paired-housed for 10 wk. During this period, they were tested for acquisition, extinction, and reacquisition of heroin (0.

Effect of meloxicam and butorphanol on minimum alveolar concentration of isoflurane in rabbits.

Objective: To determine the effects of meloxicam and butorphanol on minimum alveolar concentration of isoflurane (MAC(ISO)) in rabbits.

Animals: 10 healthy young adult female rabbits.

Procedure: Rabbits were anesthetized with isoflurane on 3 occasions in a blinded, randomized complete block design to determine the MAC(ISO) associated with administration of meloxicam (0, 0.
