EFFECT OF SESAMOL IN ASSOCIATION WITH FOLIC ACID ON 6-OHDA INDUCED PARKINSONIAN ANIMALS- BIOCHEMICAL, NEUROCHEMICAL AND HISTOPATHOLOGICAL EVIDENCE
Objective: Parkinson's disease (PD) is the world's second neurodegenerative disorder. Degeneration of dopaminergic neurons is the hallmark of the disease. Here is a novel approach to treat PD with a phenolic compound Sesamol (SA) and in combination with Folic acid (FA).
Methods: The study was designed with five groups of animals and 6 rats in each group. The rats was infused with 6-hydroxydopamine (10Î¼g/2Î¼l in 0.1% ascorbic acid saline) once for the development of PD, Group 1(control), Group 2(Lesion), Group 3(Lesion+ SA), Group 4(Lesion + SA+ FA) and Group 5(Lesion+ L-dopa). The biochemical parameter like glucose, triglycerides, protein, folic acid, TBARS and antioxidant profile in serum were estimated. The neurotransmitters level in striatum was estimated and histopathology of striatum and mid-brain tissues was carried out.
Results: The results showed that 6-hydroxydopamine induced lesion has a significant alteration in the level of glucose, triglycerides, protein and folic acid where as TBARS level was elevated and the activities of antioxidants and neurotransmitters level were reduced. This was significantly restored on SA+FA treatment. The lesion group shows an abnormal architecture of striatum and mid-brain, whereas on SA+FA treatment there was minimal abnormality.
Conclusion: Thus our study demonstrates that Sesamol has neuroprotective effect against 6-hydroxy dopamine insult and showed a synergic effect when combined with Folic acid.
