Abstract
Central administration of colchicine causes accumulation of catecholamines in nerve cell bodies and enhances their visualisation in the rat brain by the formaldehyde-glutaraldehyde (FAGLU) histofluorescence method. The detection of catecholamine-containing nerve cells by the FAGLU method was considerably improved in rats pretreated with colchicine, and adrenaline-synthesising nerve cells, which are not normally detected by the FAGLU method, could be readily localized after colchicine. The identity of the FAGLU-fluorescent nerve cells was confirmed by simultaneous immunofluorescent detection of catecholamine-synthesising enzymes in sections of the medulla oblongata. The FAGLU method applied to colchicine-treated animals could provide a simple means of detecting central adrenaline nerve cells in other species.
