Abstract：
:The effects of intraperitoneal injections of two opioid antagonists on plasma corticosterone levels in stressed mice was investigated. The effects of the mu-opioid receptor antagonist naloxone was dependent on the dose used. Low doses (0.5 and 1 mg/kg) potentiated the elevation of plasma corticosterone observed in saline treated or ether stressed mice, whereas a higher dose (10 mg/kg) produced the opposite effect. The delta-opioid receptor antagonist ICI 154,129 had no significant effect on corticosterone levels. The findings suggest that mu- rather than delta-opioid receptors are important in modifying corticosterone responses to stress and raise the question as to specificity of naloxone at doses above 1 mg/kg.
