ABSTRACT

Lipopolysaccharide (LPS) induced oxidative stress and impairment of normal physiological function generally categorized by increased anxiety and reduced mobility. Therefore, the present study was to find out the effect Methanolic extract of Asparagus racemosus (MEAR ) in lipopolysaccharide (LPS)-induced oxidative stress in rats . LPS-induced oxidative stress in rats was measured by locomotor activity by photoactometer test, anxiety with elevated plus maze test and also studied the oxidative stress markers, nitric oxide and cytokines. The obtained data shows that LPS markedly exhausted (p<0.001) brain- reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) significantly increased (p<0.001) the level of malondialdehyde (MDA), nitric oxide and the activity of cytokines in the brain. MEAR supplementation resulted in normalization of brain GSH and CAT and SOD and decreases in the levels of MDA with reduction of nitric oxide and cytokines in the brain. The action of the extract at dose of 200 mg/kg was almost similar to the standard drug, quercetin (100mg/kg, p.o.). These present study conclude that MEAR administration significantly (P<0.05) reduced LPS- induced oxidative-stress and intensely suggest that Asparagus racemosus Willd. is a functionally newer type of cerebroprotective agent.
