OBJECTIVE: To study an effect of neuroactive amino acids derivatives glufimet and mefargin on the psychoemotional state of rats after chronic alcohol intoxication (CAI). MATERIAL AND METHODS: The study was carried out on 10-month-old female Wistar rats. CAI was modeled by replacing drinking water with a 10% solution of ethyl alcohol sweetened with sucrose (50 g/l) for 6 months. Animals (age - 16 months) were divided into groups at the end of alcoholization: 1 (n=15) - intact group - rats without CAI; 2 (n=14) - control - females after CAI; 3 (n=11), 4 (n=14), 5 (n=11) and 6 (n=10) - experimental - females after CAI who received the GABA derivative mefargin (25 mg/kg), the glutamic acid derivative glufimet (29 mg/kg) and comparison drugs phenotropil (25 mg/kg) and heptral (100 mg/kg), respectively. Substances were administered to rats after 6 months of alcoholization intraperitoneally once a day for 14 days, the intact and control groups received physiological saline. The psychoemotional state of the animals was studied in the «Open field¼ test, «Elevated plus maze¼ test, «Marble burying¼ test and the Porsolt swim test after the treatment. RESULTS: In animals of the control group, an increase in anxiety was noted, as evidenced by a greater number of boluses in the Open Field test (3.43±0.56 vs. 1.47±0.39) compared to the intact group (p<0.05), short duration of stay in open arms (26.07±3.47 vs. 68.67±10.08) and fewer hangings from them (3.07±0.25 vs. 6.67±0.79) in the «Elevated plus maze¼ test. Rats after CAI buried more balls (8.79±1.15 versus 2.73±0.71, p<0.05), which indicated that they had compulsive behavior. In addition, females of the control group were observed to be depressed, as evidenced by a long period of immobilization in the Porsolt swim test (2.36±0.41 versus 0.87±0.31, p<0.05). CONCLUSION: Mefargin, glufimet, phenotropil and heptral restricted anxiety and manifestations of obsessive-compulsive disorder in females subjected to alcoholism (p<0.05). The antidepressant effect was observed in animals treated with phenotropil and heptral after CAI (p<0.05).
