Reciprocal antagonism between ACTH1-24 and beta-endorphin in rats.
ACTH1-24 and beta-endorphin simultaneously injected at 5-10 microgram dose into the lateral ventricle, reciprocally suppress most of their respective behavioural effects (stretching-yawning syndrome, sexual excitement and hyperalgesia for ACTH1-24 and catalepsy and analgesia for beta-endorphin). The results obtained support the hypothesis that ACTH1-24 and beta-endorphin might interact antagonistically at CNS level.

Failure of ketamine to interact with opiate receptors.
Ketamine, an anesthetic agent endowed with several morphine-like effects, failed to displace 3H-dihydromorphine or 3H-methionine-enkephalin from opiate receptors in the rat brain synaptosomal-mitochondrial membrane preparations. Furthermore, ketamine-induced analgesia in rats was not antagonized by naloxone, suggesting that this effect is not mediated by opiate receptors.
