ABSTRACT
AIM:
To investigate the integrative treatment of both coenzyme Q 10 ( CoQ10 ) and minocycline in the rats intranigrally intoxicated with 1-methyl-4-phenylpyridinium ( MPP+) .METHODS:
The rat model of Parkinson disease ( PD) was established by intranigral microinjection of MPP +.The degree of microglial activation was measured by immuno-fluorescent density of OX-42 ( a microglia marker ) in the substantia nigra ( SN) .The number of viable dopaminergic neurons was determined by counting the tyrosine hydroxylase ( TH) positive neurons in the SN .The behavioral performances were re-vealed with the number of apomorphine-induced rotations , score of forelimb akinesia and vibrissae-elicited forelimb placing a-symmetry.RESULTS:
Pretreatment with CoQ10 or intracerebroventricular (icv) posttreatment with minocycline alone pro-vided partial attenuation against MPP +-induced locomotor defects .Integrative therapy provided enhanced beneficial effects , and resulted in a significant attenuation of locomotor disability than any single therapy (all P<0.01).The results of immu-nohistological analysis showed that the TH positive neurons were maximally protected by integrative therapy compared with minocycline group and CoQ 10 group (P<0.01) .CONCLUSION:
The integrative therapy of CoQ 10 combined with minocy-cline may offer additional therapeutic benefit to MPP +-induced hemiparkinson rat model .Such neuroprotective strategy of tar-geting different aspect of the neurodegenerative phenotypes may highlight a new therapeutic strategy for future management of PD.
