[Measurement of in vivo incorporation of L-methionine-35S into cerebral proteins by quantitative autoradiography in freely-moving or anesthetized rats].

Incorporation of L-35S-methionine in brain proteins was measured by quantitative autoradiography in the rat. This model was checked by biochemical procedures. In awake freely moving rat, methionine incorporation rates vary from 36 to 258 nmol/100g/min. During anaesthesia, protein synthesis in brain decreases (30 to 50%).
