Phenytoin-induced serum copper and ceruloplasmin in C57BL/6J mice of different ages

Phenytoin (diphenyihydantoln) given orally to male C57BL/6J mice increased the serum copper and ceruloplasmin concentrations. Young adult mice showed a maximum increase of 107% in ceruloplasmin accompanied by a 102% increase in copper. The ceruloplasmin of middle-aged mice increased 53% and the copper 64%. For old mice the corresponding increases were 20 and 21%. Phenytoin was toxic to old mice, and middle-aged mice experienced a higher rate of death when given phenytoin for 167 days.

After 14 days, phenytoin decreased liver copper by 18% without significantly changing copper levels in kidney, brain or heart. Feeding phenytoin for 167 days lowered liver copper by 14%, increased kidney by 9% and brain by 25%. Copper in the heart remained unchanged.

We proposed that the status of copper in the brain may be important in epilepsy.
