Selegiline (L-Deprenyl) Mitigated Oxidative Stress, Cognitive Abnormalities, and Histopathological Change in Rats: Alternative Therapy in Transient Global Ischemia.

Selegiline (L-deprenyl) is the major drug which is used in the treatment of Parkinson's disease because of its neurotrophic and antiapoptotic properties. Previous studies suggested that low dose of L-methamphetamine (L-METH) caused lower mortality rate in patients with severe traumatic brain injury. As L-methamphetamine is one of the metabolites of selegiline, the present study aims to examine whether L-deprenyl can improve cognitive, biochemical, and histopathological injury in animal model of transient global ischemia. The animals were randomized in ten groups orally gavaged three times a week for 28 days. Then, novel object recognition (NOR) was conducted to assess their behavioral abnormality. After scarification of the rats, their brains were divided into two sections to measure oxidative stress parameters and perform pathological evaluations in rats. Our data revealed the involvement of oxidative stress, behavioral despair, and pathological data in transient global ischemia rats. Significant recovery in cognitive behavior, oxidative stress biomarker, and number of dead cell in histopathological assay was observed in rats treated with 1,2 and 4 mg/kg of selegiline. So, selegiline appears to be useful in alternative therapy of transient global ischemia.
