Hydroxypyruvic acid (intravenous injection; 100 mg/ml; slowly over 10 min) increases the 5-h urinary oxalate and glycolate excretion to 0.68% (6.56 μmol) and 0.53% (5.10 μmol) in control rats, in addition, it increases to 2.43% (23.36 μmol) and 0.79% (7.59 μmol) of the dose in the vitamin-B6-deficient rats.
Animal Model:
SD rat
Dosage:
100 mg/ml; slowly over 10 min
Administration:
Intravenous injection
Result:
Led to a significant increase of urinary oxalate and glycolate excretion in both control and vitamin-B6-deficient rats, but these changes are exaggerated in the vitamin-B6-deficient group.
