[Effects of oxythioquinox on urinary nitrogen excretion in rats].

The amount of nitrogen excreted in urines is higher in pair-fed Rats subjected to a diet containing 400 mg/kg of oxythioquinox. This is a consequence of specific effect of oxythioquinox on protein catabolism and not to a renal failure as is shown by the increase in the urinary excretion of urea. The administration of vitamin B6, B12 and folic acid improves the growth but these vitamins have no effect on the nature of urinary nitrogen excretion.
