摘要

BACKGROUND: Alcohol disturbances, NO stimulation (by the NO-precursor L-arginine), and/or NO-synthesis blockade (by N(G)-nitro-L-arginine methyl ester, i.e. L-NAME) were challenged with stable gastric pentadecapeptide BPC 157, which inhibits both acute alcohol intoxication and alcohol withdrawal symptoms. MATERIAL/METHODS: Mice received intraperitoneally (i.p.) BPC 157 (10 microg/kg), L-NAME (10 mg/kg), and L-arginine (400 mg/kg), alone or in combination, 5 minutes before or after acute ethanol (4 g/kg i.p.) intoxication or after 0, 3, or 7 hours of withdrawal after drinking 20% alcohol for 13 days. RESULTS: BPC 157 rapidly opposes the strongest disturbance presentations in acute intoxication (sustained ethanol anesthesia, complete loss of righting reflex, no reaction to external stimuli, hypothermia, 25% mortality) and withdrawal (prominent seizures). NO-agents: Aggravation of acute alcohol intoxication and opposition to withdrawal are common, but the later intervals affected by L-arginine and the action throughout the experiment by L-NAME are distinctive. Given together, L-arginine and L-NAME counteract each other, while either the "L-NAME presentation" (acute intoxication) or the "L-arginine presentation" (withdrawal) predominates. BPC157+NO-agent: In acute intoxication (L-NAME predominating in NO-system functioning to aggravate intoxication), both BPC157+L-NAME and BPC157+L-arginine follow the presentation of L-NAME, but without worsened mortality. In withdrawal (L-arginine predominating in NO-system functioning to oppose disturbance symptoms), BPC157+L-NAME follows the presentation of L-NAME, while BPC 157+L-arginine imitates that of L-arginine. CONCLUSIONS: The relationships among pentadecapeptide BPC 157, the NO-system, acute alcohol intoxication, and opposed withdrawal may be important, presenting pentadecapeptide BPC 157 as a suitable alcohol antagonist.
