title: [The effect of uricosuric and uricostatic drugs on DNA metabolism].
abstract: Some of the drugs, which are used in therapy of gout were tested with respect to their influence on semi-conservative DNA-synthesis and DNA-repair in vitro, using different cell systems. The agents (Benzbromarone, Allopurinol, Thiopurinol) were investigated in concentrations similar to blood-levels in normal therapy. The cells were irradiated with ultraviolet or ionizing radiation in order to damage their DNA and DNA-repair (unscheduled DNA-synthesis) was estimated by measuring the incorporation of radioactively labeled thymidine into acid insoluble material under appropriate conditions. The substances showed different effects on DNA-synthesis as well as on DNA-repair, even then, when their supposed influence on enzymes of nucleotide metabolism, was similar.
