Evaluation of Antioxidant and Anti Parkinsonism Activity of Betaine in Experimental Rats
Aim and Objectives: The present study was aimed to evaluate anti parkinsonium effect of Betaine for its Applications in trigger factors in pathogenesis of Parkinson’s disease and to understand development of new treatments approaches for PD. Betaine is naturally obtained product. It has antioxidant, neuroprotective activity. Hence, we inspected whether betaine can act as a protective agent in 6-OHDA induced oxidative stress on cerebellum of Sprague-Dawleyrats.
Material and Methods Thirty-six adult Sprague-Dawley rats were dived into six groups. Rats were received unilateral 6- hydroxydopamine lesions for induction except normal and rats were treated with respective treatment. At the day of 21 rats were sacrificed. Prepared brain homogenate was used for further Biochemical estimation.
Result: Betaine showed marked rise in SOD and Catalase activity as well as GSH content subsequently decreasing in the lipid peroxidation process. Our result suggests Betaine to be potent antioxidant at dose 12.5 and 25 mg/kg as compared to standard (L-dopa+Benserazide) and pro-inflammatory cytokines viz: TNF-α, IL-1β and IL-6 were significantly reversed by Betaine as compared to that of standard group (L-dopa+ Benserazide).
Discussion and Conclusion: Betaine showed dose dependent effect by reducing LPO level as increasing SOD, GSH and Catalase activity and marked reduced proinflammatory cytokine, hence we conclude that betaine has good anti parkinsonism activity.

Ghrelin mediated regulation of neurosynaptic transmitters in depressive disorders
Ghrelin is a peptide released by the endocrine cells of the stomach and the neurons in the arcuate nucleus of the hypothalamus. It modulates both peripheral and central functions. Although ghrelin has emerged as a potent stimulator of growth hormone release and as an orexigenic neuropeptide, the wealth of literature suggests its involvement in the pathophysiology of affective disorders including depression. Ghrelin exhibits a dual role through the advancement and reduction of depressive behavior with nervousness in the experimental animals. It modulates depression-related signals by forming neuronal networks with various neuropeptides and classical neurotransmitter systems. The present review emphasizes the integration and signaling of ghrelin with other neuromodulatory systems concerning depressive disorders. The role of ghrelin in the regulation of neurosynaptic transmission and depressive illnesses implies that the ghrelin system modulation can yield promising antidepressive therapies
