Chlorpyrifos induced alterations in levels of thiobarbituric acid reactive substances and glutathione in rat brain.
Chlorpyrifos, O,O'-diethyl-O-3,5,6-trichloro-2-pyridyl phosphorothionate, exposure in rats caused significant inhibition of acetylcholinesterae activity in different regions of brain and generated oxidative stress as evidenced by increase in the level of thiobarbituric acid reactive substances and decrease in the ratio of reduced to oxidized glutathione in all the three regions of brain. Malondialdehyde level was increased significantly in all regions of brain and the increase was dose dependent. Mid brain showed highest level of lipid peroxidation.
