Excitatory Amino Acids 82-85 arginine vasopressin Rattus norvegicus 127-138 1359961-4 1992 Finally, we investigated whether different periods of exposure (up to 100 min) of hypothalamic explants to NMDA and KA would affect CRH-41 release. N-Methylaspartate 107-111 corticotropin releasing hormone Rattus norvegicus 132-135 1359961-5 1992 While no EAA was able to induce CRH-41 release under any of the above conditions, 20-min incubations with NMDA in the dose range of 1 nM to 1 mM in the absence of added Mg2+ significantly stimulated AVP release in a dose-related fashion; the maximum effect occurred at a concentration of 1 mM [ratio of stimulated collection/basal collection: NMDA, 1.51 +/- 0.10, controls, 0.86 +/- 0.05 (mean +/- SEM); P < 0.001].
