1 Dynorphin A-(1-13) potently improves scopolamine-induced impairment of passive avoidance response in mice. Scopolamine prodynorphin Mus musculus
2 The effects of intracerebroventricular administration of dynorphin A-(1-13) on scopolamine-induced amnesia were investigated in mice by using a step-down type passive avoidance task. Scopolamine prodynorphin Mus musculus
3 Dynorphin A-(1-13)(1 microgram) given 15 min before training and retention tests but not immediately after training significantly improved the scopolamine (1 mg/kg)-induced shortening of step-down latency of the passive avoidance response, indicating antiamnesic effects of dynorphin A-(1-13) (1 microgram). Scopolamine prodynorphin Mus musculus
