The effects of dynorphin A (1-13) on carbon monoxide (CO)-induced amnesia in mice were investigated. Memory deficiency was apparent during Y-maze testing 5 days after CO exposure (delayed amnesia). Percent alternation in the CO-exposed group was significantly lower than that in the control group. Administration of dynorphin A (1-13) (1.5 nmol, i.c.v.) 15(More)
The effects of dynorphin A-(1-13) on carbon monoxide (CO)-induced amnesia in mice were investigated using a step-down type passive avoidance task. Memory deficiency occurred in mice when training commenced 7 days after CO exposure although it was not produced 1 day after CO exposure. The median step-down latency in the retention test of the CO-exposed group(More)
