Serum glutamate dehydrogenase and ornithine carbamyl transferase in Reye's syndrome

Parallel increases in the ornithine carbamyl transferase and glutamate dehydrogenase activities were observed in the serum of 22 Reye's syndrome patients. The increase in the activity of glutamate dehydrogenase was masked by a dialyzable inhibitor. It is proposed that the measurement of serum ornithine carbamyl transferase and glutamate dehydrogenase activities may be useful as an indicator of liver mitochondrial damage in Reye's syndrome.
