Regional uptake of [35S]-cysteine in rat brain after arterial injection.
The brain uptake index of [35S]-cysteine in ten rat brain regions and in the eye was determined by measuring [35S]-cysteine remaining in the brain regions and in the eye, five seconds after carotid injection, relative to a simultaneously injected diffusible internal standard, 3H2O and a non-diffusible internal standard Tc99m-Sn-DTPA. A statistical comparison for the regions that receive their blood supply from the internal carotid artery was done. Only the diencephalon and the septum-nucleus accumbens were found significantly higher than cortex.
