  • Abstract
  • Look Inside

Crystalline lenses of rats were cultured on T C medium 199 to which 14C labeled α-amino iso-butyric acid (AIB) was added to examine ch-anges due to the aging in the transport of ami-no acid into the lens.

Then, by the use of metabolic inhibitors, ef-fect of aging on the inhibition of active trans-port of amino acid was studied.

As the result, the following findings were obtained:

(1) 14C AIB was actively transported into the lens fairly rapidly.

In the Infant and youthful group, ac-cumulation of amino acid increased in pro-portion to the period of time until hours.
