title: Urinary purine levels in suicide.
abstract: A high-resolution liquid chromatographic system was utilized to analyze urine samples of twelve nonchemical suicide victims for the relative composition of ultraviolet-absorbing compounds. The analyses demonstrated a decrease in the output of uric acid, characteristic of severe depression, and an increase in the excretion of hypoxanthine. The excretion of 7-methylxanthine was found to be variable and xanthine was normal.
