title: Ageing of the spinal ganglion neurons in the rat: a radioautographic study following injection of [3H]lysine.
abstract: After administration of [3H]lysine to 3- and 24-month-old rats, radioautography demonstrates a significantly less important uptake in the A-type spinal ganglion neurons and in the old animals. This is in agreement with the existence of at least two functional categories of neurons in the spinal ganglion and suggests that protein synthesis is diminished in the old animals. The very fact that incorporation varies between animals of the same age sustains the hypothesis according to which amplitude of ageing is essentially an individual physiological-dependent process.
