摘要
Rotenone (organic pesticide and inhibitor of mitochondrial complex I) is used to generate an experimental model of Parkinson's disease (PD). In the present study, we investigated rotenone -induced locomotor deficits, gait dynamics and muscular weakness in rats. The study also determined dopamine (DA) and dihydroxyphenylacetic acid (DOPAC) levels following rotenone administration. In the study, adult male rats were administered subcutaneously (s.c.) with rotenone (1.5 mg/kg/day) for 8 days. Motor activities were monitored by the Kondziela's inverted screen test, beam walking test and footprint test. Animals were decapitated after behavioral analysis and brains were dissected out for neurochemical estimation. Results showed that the levels of DA and DOPAC were significantly decreased, which further supported by significant impaired motor coordination in rotenone treated rats. In conclusion, the behavioral and neurochemical findings of our study further strengthen the previous report and emphasizes on short term administration of rotenone producing PD -like symptoms in rats.
