Relationship of calcium and magnesium contents in mouse brain to electric acupuncture analgesia has been well studied. Recently workers found that both analgesic effects of electric acupuncture and morphine not only were similar, but also had a common ionic basis. The subcellular loss of calcium after opiate administration was found to be associated with fractions rich in nerve endings and was closely parallel to the subcellular distribution of opiate receptor binding, and was shown to be influenced by a number of inorganic ions, particularly monovalent and divalent cations implicated
