Investigation of the oxidative status in patients with Parkinson's disease

Currently, much attention is paid to the search for laboratory diagnostic tests for Parkinson's disease, which can be used to create a screening diagnostic panel. The aim of the research was to study markers of oxidative status in blood plasma and to correlate these indicators with the main clinical characteristics of Parkinson's disease. Material and Methods. The study included 32 patients of the main group and 21 patients as a control group. Blood was collected for the evaluation of total oxidative activity and general antioxidant status of the organism (OOAand OAA): determination of the activity of catalase, superoxide dismutase (SOD), malonic dialdehyde (MDA) in the blood serum by spectropho- tometric method. Results. The parameters of SOD, catalase, ОАА, OOA in patients with early stage of Parkinson's disease significantly differed from those of the control group Conclusion. Reduction of oxidative activity could slow down the development of the disease.
