Abstract
Abstract— Total cholinesterase, acetylcholinesterase, (AChE) and monoamine oxidase (MAO) activity and protein content were determined throughout the embryonic life of the chick in spinal and sympathetic ganglia. The greatest part of total cholinesterase activity was due to AChE.AChE and MAO activity increased in both spinal and sympathetic ganglia very similarly from the 6th to the 12th day of incubation; from this day on a significant divergence occurred, mainly owing to a steady fall in spinal ganglion AChE, which decreased to approximately one tenth of the maximum value. The ratio of MAO activity in sympathetic and spinal ganglia increased from the 8th day onwards and approached 5·0 at hatching. The ratio between sympathetic and spinal ganglia, for AChE, choline acetylase (ChAc) and MAO activity, suggests a relationship between the maturation of the synapse in the sympathetic ganglia and the maximal activity of these enzymes.
