| Abstract: | Context Quercetin (QE), a bioflavonoid present abundantly in fruits and vegetables, has been reported to possess antioxidant properties. Acrylamide (ACR) is formed in foods during cooking and is known to be neurotoxic.Objective The present study was designed to evaluate the protective effect of QE against neurotoxicity induced by ACR.Materials and methods Four groups of Wistar rats consisting of six rats each: (i) control group; (ii) acrylamide treated group (50?mg/kg body weight as single dose); (iii) quercetin group: rats were treated intraperitoneally (i.p.) with QE (10?mg/kg body weight alone every day for 5 d); (iv) quercetin?+?acrylamide group: quercetin (10?mg/kg bw) was given i.p. every day for 5 d followed by acrylamide i.p. injection (50?mg/kg bw) on fifth day (single dose). Rats were killed after 48?h.Results Administration of ACR (50?mg/kg bw) in Wistar rats resulted in significant increase of dopamine, interferon-γ and 8-hydroxyguanosine with concomitant decrease of serotonin (p?p?p?Discussion and conclusion On the basis of the above results, the present study suggests that quercetin may be a potential therapeutic agent for restoration of oxidative damage to neurons. |
