Using the C1/C6 14CO2 ratio as a relative measure of pentose shunt metabolism, rat brain prisms were incubated with (1-14C) or (6-14C) glucose and respired 14CO2 collected. Shunt metabolism was stimulated with 10-4 but not 10-5M norepinephrine. MAO inhibitors and reserpine blocked norepinephrine stimulation but uptake inhibition did not. These data demonstrate that, under the tested conditions, MAO mediated norepinephrine metabolism does stimulate shunt activity but not at physiological concentrations.
