Opioid and non-opioid stress analgesia: assessment of tolerance and cross-tolerance with morphine.
Opioid and non-opioid mechanisms of analgesia elicited by two kinds of footshock stress that differ only in temporal characteristics previously have been inferred on the basis of susceptibility to naloxone blockade. The present study sought further evidence on this point by comparing these two kinds of footshock analgesia for possible tolerance development and cross-tolerance with morphine. It ...
متن کاملTwo opioid forms of stress analgesia: studies of tolerance and cross-tolerance.
We have previously reported that stress analgesia sensitive to and insensitive to opiate antagonists can be differentially produced in rats by varying the severity or temporal pattern of inescapable footshock. In these studies, we give further evidence for the opioid and non-opioid bases of these paradigms of stress analgesia. We find that naloxone-sensitive analgesia demonstrates tolerance wit...
متن کاملRimonabant attenuates sensitization, cross-sensitization and cross-reinstatement of place preference induced by nicotine and ethanol.
The present study focused on the evaluation of behavioral sensitization, cross-sensitization, and cross-reinstatement processes induced by nicotine and ethanol in rodents. First, we showed that nicotine (0.175 mg/kg, base, intraperitoneally, ip) produced a conditioned place preference in rats. When the nicotine place preference was extinguished, nicotine-experienced animals were challenged with...
متن کاملAnalgesia induced by electroacupuncture of different frequencies is mediated by different types of opioid receptors: another cross-tolerance study.
The cross-tolerance technique was used to analyze the receptor mechanisms of analgesia induced by electroacupuncture (EA) of 2 Hz, 100 Hz, or 2-15 Hz. (1) Rats were given EA stimulation of 2 Hz, 100 Hz and 2-15 Hz for 30 min with 30 min intervals successively. The percentage increase in tail-flick latency (TFL) was taken to indicate the intensity of EA analgesia. Rats made tolerant to repeated ...
متن کاملReciprocal cross-sensitization between amphetamine and salt appetite.
Previous work in our laboratory has demonstrated a potentiation of the psychomotor effects of amphetamine in animals with a history of sodium depletion, a process referred to as cross-sensitization. The present studies were done to further develop this finding by assessing multiple effects of amphetamine in rats with and without a history of sodium depletion. For Experiments 1-3, rats were depl...
