Abstract

1. 1. The uptake of 14C-ascorbic acid by the iris-ciliary body in vitro was examined in the rabbit, guinea pig and rat. 2. 2. It was observed that iris-ciliary body from the rabbit and guinea pig, but not the rat, accumulated 14C-ascorbate to levels exceeding that in the bathing medium. 3. 3. In all three species, the uptake of 14C-ascorbate was diminished by cold temperature; the degree of uptake at 0°C was similar in the rabbit, guinea pig and rat iris-ciliary body. 4. 4. Chromatographic examination of the 14C accumulated by the rabbit and guinea pig tissue demonstrated that the label remains almost exclusively as 14C-ascorbate.
