Antioxidant effects on the intracerebroventricular galactose damage in rats.

We investigated the effects of the intracerebroventricular infusion of galactose and the influence of pretreatment with antioxidants on oxidative stress parameters and acethylcholinesterase (AChE) activity in the brain of 60-day-old Wistar rats (6 per group). The animals were divided into naïve group (did not undergo surgery); procedure group (only underwent surgery); sham group (underwent surgery and received 5 μL saline) and galactose group (received 5 μL of galactose solution (5.0 mM) by intracerebroventricular injection), and were killed by decapitation after 1 h.
