Recent Studies on the Therapeutic and Prophylactic Effect of Some Agents on Experimental Induced Parkinson Disease Models Review

Abstract

Neurodegeneration include disease of the central nervous system (CNS) such as Parkinson’s disease (PD). The sign of this disease include destruction of dopaminergic neuronal cells. Main causes of this disease are unknown, but several studies reported polygenic causes. These include free radicals, malfunction of mitochondria, protein oxidation and DNA denaturation. Several reports implicated the involvement of oxygen species and stresses cause by over accumulation of reactive oxygen species in the contribution to the cascade that resulted in diminishing of dopamine cells destruction in this disease. Generally, natural defensive substances such as bio-cartelized (proteineous and non proteineous) from natural or synthetic sources played a unique role in protecting the susceptible neuronal cells from the adverse effects of the reactive oxygen species. In most cases antioxidant enzyme production by the body system diminished with advance age. Hence, treatment with antioxidant potential agent or administration of antioxidant substance with the Review Article Hassan and Abdullahi; AJRB, 8(2): 1-18, 2021; Article no.AJRB.63383 2 common drugs used in the treatment of PD may yield positive result in protecting neurons from degenerative changes caused by reactive oxygen species. Recent studies on the therapeutic and prophylactic effect of some agents on experimental induced PD summarized in this review paper.
