it was found that delta-receptor binding , assessed with [ 3h ] d-ala2-d-leu5-enkephalin ( [ 3h ] dadle ) ( + 10 nm d-ala2- mephe4-gly-ol5-enkephalin ( damge ) ) , was stimulated by the 3 cations in a dose- and developmental time-dependent manner . delta-binding was most sensitive to the cations during the first week postnatal , prior to the appearance of high-affinity delta-binding .
