title: [A comparison of the effects of haloperidol when administered systemically and injected into the striatum of rats].
abstract: The effects of chronic intraperitoneal (2 mg/kg) and bilaterally intrastriatal (5 micrograms) haloperidol were studied in albino male rats. Intraperitoneal injections resulted in inhibition of conditioned avoidance reflexes and catalepsy. After intrastriatal microinjections, the Parkinsonism-like status appeared along with akinesia and rigidity; that effect was recorded on day 7 of the experiment, which lasted up to the first few days of haloperidol withdrawal. The causes of distinctions between the effects of systemic and local intrastriatal haloperidol injections are discussed.
