Growth inhibitor of calcium oxalate monohydrate crystal in vitamin B6-deficient rat urine and kidney.

Urinary and renal inhibitory activities of calcium oxalate monohydrate crystal growth in normal or vitamin B6-deficient rats were investigated. Renal inhibitory activity in vitamin B6-deficient rats was lower than that in normal rats. Renal inhibitory activity in vitamin B6-deficient rats was about 74% of normal level. Urinary inhibitory activity did not show a significant difference between normal and vitamin B6-deficient rats.
