Concentration of radioactivity (nanocuries per gram) in tissues of four Sprague-Dawley male rats at 15 min after a single intravenous bolus dose of [3H]glucose
Mean radioactivity values were calculated by averaging 1) tissue concentrations measured at different sectioning levels and/or 2) tissue concentrations measured from replicate cryosections obtained from the same sectioning level; n values range from a minimum of 3 to a maximum of 12.
