Sažetak
Previously, the gastric pentadecapeptide BPC 157, (PL 14736, Pliva) has been shown to have several beneficial effects, it exert gastroprotective, anti-inflammatory actions, stimulates would healing and has therapeutic value in inflammatory bowel disease. The present study aimed to study the effect of naloxone and BPC 157 on morphine-induced antinociceptive action in hot plate test in the mouse. It was found that naloxone and BPC 157 counteracted the morphine (16 mg/kg s.c.) - analgesia. Naloxone (10 mg/kg s.c.) immediately antagonised the analgesic action and the reaction time returned to the basic values, the development of BPC 157-induced action (10 pg/kg, 10 ng/kg, 10 microg/kg i.p.) required 30 minutes. When haloperidol, a central dopamine-antagonist (1 mg/kg i.p.), enhanced morphine-analgesia, BPC 157 counteracted this enhancement and naloxone reestablished the basic values of pain reaction. BPC 157, naloxone, and haloperidol per se failed to exert analgesic action. In summary, interaction between dopamine-opioid systems was demonstrated in analgesia, BPC 157 counteracted the haloperidol-induced enhancement of the antinociceptive action of morphine, indicating that BPC acts mainly through the central dopaminergic system.
