Abstract

Effects of Met-enkephalin (Met-ENK) and opioid antagonists on H₂O₂ release by peritoneal macrophages from DA and AO rats were investigated. Met-ENK increased and decreased H₂O₂ production by macrophages of DA and AO rats, respectively. These effects were antagonized by low, but not high, concentrations of naloxone and ICI 174864. High concentrations of both antagonists directly modulated H₂O₂ release and retained the strain-related differences seen with Met-ENK. The results showed direct, strain- and dose-dependent, effects of Met-ENK, naloxone, and ICI 174864 on rat macrophage function.
