we investigated the effect of morphine dependence on the migrating myoelectric complex ( mmc ) of the small intestine , whether bacterial overgrowth developed in morphine-dependent rats , and the effect of naloxone , 0.5 mg/kg sc , and methylbromide naltrexone , 1.0 mg/kg sc , a peripheral opioid antagonist , on the mmc in morphine-naive and morphine-dependent rats .
