title: The effect of ageing on the histochemically demonstrable catecholamines in the hypogastric (main pelvic) ganglion of the rat.
abstract: The effect of ageing on adrenergic neurons was studied in the hypogastric ganglion of the male rat using the formaldehyde-induced fluorescence method. With age, two changes were obvious. Firstly, the fluorescence intensity of the neurons decreased throughout postnatal life and the number of completely non-fluorescent adrenergic neurons increased. Secondly, the amount of non-specific fluorescence due to lipofuscin pigment increased. The pigment fluorescence was also found around the neurons in satellite cells.
