[Propionic acidemia and sodium dipropylacetate].

After administering sodium dipropylacetate to normal rats and biotin-deficient rats, we observed a slight hyperglycinemia, significant constant hyperglycinuria, but no accumulation of propionic acid in the blood or significant urinary elimination. Hepatic propionyl-CoA carboxylase activity, in vivo and in vitro, did not change, neither did sodium dipropylacetate inhibit propionyl-CoA carboxylase nor induce propionic acidemia resulting from a deficiency in this enzyme.
