Abstract :
Aim: To evaluate the effect of Aqueous extract of Terminalia belliricafruit pulp (AETB) on learning by Hebb William maze model in mice with acute alcohol consumption.
Materials and Methods: Swiss albino mice (n=48) of either sex weighing 20-30g will be divided into eight groups of six mice each. Drugs were given orally after 12 hours of fasting. Group I mice received 10ml/kg of Normal Saline, Group II mice received Piracetam 200mg/kg, Group III received AETB 36mg/kg, Group IV received ethanol 1.5g/kg orally, Group V received ethanol(1.5g/kg ) piracetam (200mg/kg), Group VI mice received ethanol(1.5g/kg) AETB(9mg/kg), Group VII mice received ethanol(1.5g/kg) AETB (18mg/kg), Group VIII mice received ethanol(1.5g/kg) AETB(36mg/kg). Time taken by the animal to reach the reward chamber from the start chamber (TRC) in Hebb-William maze was used as a parameterto evaluate the learning.
Results: Acute alcohol administration showed increase in TRC. Whereas, acute administration of Aqueous extracts of Terminalia belliricafruit pulp showed a decrease in TRC when compared to the control group. The TRC values for the groups that were administered AETB along with acute alcohol administration showed decrease in TRC values compared to the negative control.
Conclusion: Current study showed acute alcohol administration caused impairment of thelearning ability in mice. Whereas, acute administration of Aqueous extracts of Terminalia belliricafruit pulp (AETB)caused enhancement of learning. Pre-treatment with AETB before acute alcohol administration indicated protective action of AETB on alcohol affected learning in mice.
