متن کاملNucleoside transport mechanisms in the pigmented rabbit conjunctiva.
PURPOSE To elucidate the mechanisms of nucleoside transport in the pigmented rabbit conjunctiva using [3H]uridine as the substrate. METHODS Excised pigmented rabbit conjunctiva was mounted in a modified Ussing chamber for measurement of short-circuit current (Isc) and [3H]uridine transport. RESULTS [3H]Uridine transport in the mucosal-to-serosal direction at 10 microM exhibited directionali...
