title: Amino acid transport by corneal epithelial cells from the toad, Bufo marinus.
abstract: alpha-Aminoisobutyric acid is actively accumulated by the epithelium of the cornea of the toad, Bufo marinus, resulting in a tissue to medium ratio of 4 to 1 after 40 min of incubation. The accumulation of alpha-aminoisobutyric acid is ouabain-sensitive and dependent upon the presence of extracellular sodium. Transport is inhibited by carbon monoxide, 6-aminonicotinamide, arsenite and n-heptyl-3-hydroxy-quinoline-n-oxide and stimulated by diamide.
