Abstract
1. An established procedure for determining oxalate in human urine has been modified for rat urine. The daily excretion of oxalate by the male Wistar rat is 570-650 μg.
2. Oxalate excretion in rat urine following i.p. administration of [14C]oxalic acid (1-70mg/kg) has been studied. The rate and degree of excretion are dose-dependent.
3. The excretion of urinary oxalate by the rat has been quantified after administration of two oxalate-producing xenobiotics, α-chlorohydrin and 1,2-dibromo-3-chloropropane.
4. Oxalate inhibits the metabolism of glucose and lactate by isolated rat kidney tubules in vitro.
