چکیده
The purpose of the present work was to study the dose-effect relationship of the antidepressant amitriptyline on inhibitory avoidance in male and female mice. Subjects received physiological saline or 2.5, 5, 10 or 20 mg/kg of amitriptyline hydrochloride 30 min before the training phase, and were subjected to the test phase 24 h later. Results showed a clear impairing effect of amitriptyline on inhibitory avoidance in both male and female mice, and that the effect is dose-dependent.

Morphine sensitization and state-dependent learning in mice
In the present study, the effects of morphine sensitization on morphine-induced impairment of memory formation and the state-dependent retrieval of a passive avoidance task learned under morphine influence have been investigated in mice. Pre-training administration of morphine (0.5, 2.5 and 5 mg/kg) dose dependently suppressed the learning of one-trial passive avoidance task. Pre-test administr...

These experiments examined the effects of pre-test intra dorsal hippocampus (intra-CA1) administration of GABAA receptor agonist and antagonist, muscimol and bicuculline respectively, on state-dependent learning induced by lithium. Male NMRI mice were trained in a one-trial step-down inhibitory avoidance task, and immediately after training they received IP injections of either saline (10 mL/kg...

Introduction: Epilepsy is one of the most common neurologic disorders. Pharmacoresistance and adverse effects of current antiepileptic drugs (AEDs) necessitate development of new drugs and strategies for treatment of epilepsy. Omega 3-Polyunsaturated fatty acids (ω3-PUFAs) are safe nutritional supplements that recently considered for treatment of epilepsy. Anticonvulsant effect of docosahexa...
