[Histochemistry and choline acetyltransferase in cat spinal cord and spinal ganglia].
Cytochemical activity of choline acetyltransferase has been studied in the pericaryon of motor neurons of the spinal enlargement and sensitive neurocytes of the intervertebral ganglia in the cat by means of Burt's method. It has been demonstrated that cytoplasm of all motor neurons positively reacts with acetyl KoA. According to the activity of choline acetyltransferase, four groups of neurons have been determined. In cerebrospinal ganglia, the enzyme is present in 58% of pseudounipolar cells, which seem to be cholinergic neurocytes. It has been stated that for all nonspecific reactions the presence of massive and dense residue in all the neurons, walls of small blood vessels and sometimes in astrocytes is a characteristic feature.
