Objective: 

The aim of this study was to observe whether the neuroprotective effects of DHA in an experimental Parkinson model is related with alterations in iNOS and Bcl-2 expressions.

Methods: 

Adult male Wistar rats were divided into 4 groups: Control; DHA-treated; MPTP-induced; MPTP-induced+DHA-treated. Motor activity was investigated by vertical pole test. The lesion was determined by immunohistochemical analysis for tyrosine hydroxylase (TH)-immunopositive cells in substantia nigra (SN). Immunoreactivities of iNOS and Bcl-2 in SN were evaluated by immunohistochemistry.

Results: 

MPTP-induced animals exhibited decreased locomotor activity and motor coordination. Diminished symptoms and decreased dopaminergic neuron death were detected in the MPTP-induced+DHA-treated group compared to MPTP-induced group. iNOS immunoreactivity increased in MPTP-induced group compared to control and DHA, however it was decreased in the MPTP-induced+DHA-treated group compared to the MPTP-induced group. The staining intensity for Bcl-2 decreased in the MPTP-induced group compared to control, while it was stronger in the MPTP-induced+DHA-treated group compared to MPTP-induced group.

Conclusions: 

The alterations in the expression levels of iNOS and Bcl-2 would be possible factors in neuroprotective effects of DHA in experimental model of Parkinson's disease.
