| pubmed-article:6821193 | pubmed:abstractText | The possibility that divalent cations may antagonize opiate peptide analgesia and stress-induced analgesia was examined. Intracerebroventricular injection of low doses of Ca2+, Mn2+ and Mg2+ antagonized beta-endorphin and methionine-enkephalin analgesia. Ba2+ and Cd2+ were without effect. The ionophore, A23187, significantly antagonized beta-endorphin analgesia and the effect was increased when a low dose of Ca2+ was injected at the same time as the ionophore. Ethylene glycol tetraacetic acid (but not ethylenediamine tetraacetic acid) significantly potentiated endorphin analgesia. Stress-induced analgesia, as determined by increased tail-flick latencies following intraperitoneal injection of acetic acid, was effectively antagonized by naloxone, Ca2+ and Mn2+. The frequency of writhing following acetic acid injection was increased by both naloxone and divalent metal ions, again suggesting antagonism of endogenous opiates. These results confirm previous findings indicating that divalent metal ions (and especially Ca2+) may be involved in the actions of opiates. | lld:pubmed |
