[Enzymo-chemical organization of the receptors of the aortic reflexogenic zone in dog ontogenesis].
By means of some histochemical methods in the aortal reflexogenic zone receptors succinate dehydrogenase (SDG), monoaminoxidase (MAO) and cholinesterase (ChE) activity has been studied during canine ontogenesis. Differentiation of the compact receptors is accompanied with certain changes of their enzymochemical characteristics. By the end of the first week of the intrauterine life, in the structures of the canine compact receptors certain SDG and ChE activity is detected. In 15-day-old puppies the aortal compact receptors do not differ by their enzymatic activity from similar sensitive terminals in mature animals. The topography of the enzymatic activity corresponds to the definitive one at the age of 2-3 months.
