BR-16A protects against ECS-induced anterograde amnesia.

چکیده
BR-16A is an herbal (non allopathic) medication used in India to enhance cognition. In experiment 1, 28 Wistar rats received either BR-16A (200 mg/kg/day) or vehicle alone for 3 weeks. During the third week, the rats were tested for learning in the Hebb Williams complex maze. BR-16A-treated rats showed significantly better learning than did controls. Experiment 2 was conducted identically except that during the second week all of 32 rats additionally received six once-daily electroconvulsive shocks (ECS). An advantage for learning was again demonstrated for the BR-16A group. It is concluded that BR-16A facilitates learning, and that this effect extends to a protection against ECS-induced anterograde amnesia. Cognitive deficits induced by electroconvulsive therapy are a major disadvantage of the treatment and, to-date, no drug has been found to offer satisfactory protection against such deficits. It is suggested that BR-16A may hold promise in the containment of electroconvulsive therapy (ECT)-induced cognitive compromise.

BR-16A is a herbal (non-allopathic) medication used in India to enhance cognition in this study. Wistar rats (n=24) received either BR-16A (200 mg/kg/day) or vehicle alone for 3 weeks. Over 4 consecutive days during the third week, the rats were tested for learning in the Hebb Williams complex maze. BR-16A treated rats showed significant learning while controls did not. It is concluded that BR-...

Forty nine adult male Sprague Dawley rats were selected for rapid learning in a T-maze to study the effects of BR-16A, a herbal preparation on ECS-induced retrograde amnesia. Half the rats received 200 mg/kg BR-16A and the other half received vehicle alone. The rats were trained to run into the enclosed chamber of either the left or the right arm on a T-maze; a food pellet served as a reward in...

BR-16A (Mentat 50-500 mg/kg) improved acquisition and retention of a passive avoidance task in a step-down paradigm in mice. BR-16A (50-500 mg/kg) reversed scopolamine (0.3 mg/kg)-induced disruption of acquisition and retention. BR 16-A (50 and 100 mg/kg) attenuated amnesia produced by the acute treatment with electroconvulsive shock (ECS), immediately after training. Chronic treatment with ECS...

The effectiveness of BR-16A, a herbal psychotropic preparation, was investigated in shortterm memory paradigms in mice. The passive avoidance task consisted of an electric grid with a centrally located shock-free zone (SFZ). BR-16A (50-500 mg/kg) improved passive avoidance acquisition as well as retrieval in mice. BR-16A reversed scopolamine (0.3 mg/kg)-induced disruption of learning and memory...
