Steroidal anti inflammatory drug betamethasone significantly alters level of striatal dopamine in a rat model of Parkinson’s disease
Many scientific efforts have been well done to investigate the effects of anti inflammatory agents on the degenerative brain diseases such as Parkinson’s (PD) or Alzheimer’s disease and their affiliated sings. Previously we showed the effectiveness of steroids on rigidity of PD and in the study for further mechanistic investigation of that observation the microdialysis technique was employed to determine the striatal dopamine changes in parkinsonian rats after administration of betamethasone (0.12, 0.24 mg/kg) respectively. Our findings showed us the significant increase in the striatal dopaminergic neurotransmission (P<0.05) after administration of betamethasone comparing to the controls. These observations suggest a new mechanism for betamethasone on striatum dopaminergic neurotransmission leading us to gather further evidence about effectiveness of betamethasone in PD
