Modulation of MK-801-induced behaviour by noradrenergic agents in mice.

abstract：:When tested in adulthood, male rats that had been treated daily with 50 mg/kg hydroxyzine HCl SC at 10--29 or 23--29 days of age were significantly facilitated in performance of delayed spontaneous alternation relative to saline-injected rats. Treatment at 10--16 days of age did not produce significant facilitation in...
