We hypothesized that there would be decreased BDNF expression in TD, but that treatment with EGb761 would increase BDNF expression and reduce TD manifestations in a rat model. Forty rats were treated with haloperidol (2 mg/kg/day via intraperitoneal injections) for 5 weeks. EGb761 (50 mg/kg/day) and vitamin E (20 mg/kg/day) were then administered by oral gavage for another 5 weeks, and we compared the effects of treatment with EGb761 or vitamin E on haloperidol-induced vacuous chewing movements (VCMs) and BDNF expression in four brain regions: prefrontal cortex (PFC), striatum (ST), substantia nigra (SNR), and globus pallidus (GP). Our results showed that haloperidol administration led to a progressive increase in VCMs, but both EGb761 and vitamin E significantly decreased VCMs. Haloperidol also decreased BDNF expression in all four brain regions, but both EGb761 and vitamin E administration significantly increased BDNF expression. Our results showed that both EGb761 and VE treatments exerted similar positive effects in a rat model of TD and increased BDNF expression levels in the four tested brain regions, suggesting that both EGb761 and vitamin E improve TD symptoms, possibly by enhancing BDNF in the brain and/or via their free radical-scavenging actions.]]> Sat 24 Mar 2018 07:41:01 AEDT ]]> Altered interleukin-18 levels are associated with cognitive impairment in chronic schizophrenia https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:29669 Sat 24 Mar 2018 07:32:21 AEDT ]]> Cognitive impairments in first-episode drug-naive and chronic medicated schizophrenia: MATRICS consensus cognitive battery in a Chinese Han population https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30079 Sat 24 Mar 2018 07:31:17 AEDT ]]> Mn-superoxide dismutase activity is associated with orofacial involuntary movements in schizophrenia patients with tardive dyskinesia https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26418 Sat 24 Mar 2018 07:27:57 AEDT ]]> Altered BDNF is correlated to cognition impairment in schizophrenia patients with tardive dyskinesia https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:22968 Sat 24 Mar 2018 07:15:20 AEDT ]]>
