Abstract

The present study was taken up to see the effect of chicoric acid (CA) on behavioral and biochemical alterations induced by chronic restraint stress in experimental Swiss albino mice. CA at 1mg/kg dose level exhibited considerable antidepressant activity as shown by significant decrease in immobility period in the Porsolt's swim stress-induced behavioral despair test and escape failures in Learned "helplessness test". The antidepressant activity shown by CA can be attributed to its modulating effect on nor-adrenaline (NA), dopamine (DA) and 5- hydroxy tryptamine (5-HT) as shown by their quantification in CA treated chronically stressed mice. Further, a significant antioxidant effect was exhibited by CA as shown by estimation of lipid peroxidation, glutathione (GSH) and glycogen in liver of chronically stressed mice. It also normalized altered values of serum glucose, triglycerides, aspartate aminotransferase (AST) alanine aminotransferase (ALT) and alkaline phosphatase (ALP) in a dose dependent manner. The stress busting potential of CA was further confirmed by its regulating effect on raised plasma corticosterone levels and significant attenuation of the depleted ascorbic acid, cholesterol and corticosterone levels in adrenal glands. Thus, our results suggest that CA possesses considerable stress busting potential, and that anti-oxidation may be one of the mechanisms underlying its antistress action.Copyright © 2011 Elsevier Inc.
