    Abstract:
    The effects of zinc, the NMDA receptor inhibitor, were studied in the forced swimming (Porsolt's) test in mice. Zinc (ZnSO4) at a dose of 30 mg/kg (but not at a dose of 10 mg/kg), similarly to imipramine (30 mg/kg), reduced the immobility time in that test. Moreover, zinc at both doses reduced the locomotor activity. The obtained results indicate that zinc induces an antidepressant-like effect in the forced swimming test. Since zinc reduces the locomotor activity, this antidepressant-like effect is not related to the alteration of general activity.
