[Enzymatic activity of neurons of various parts of the digestive tube in postnatal ontogenesis of the rat (cytophotometric histochemical study)].
Enzymatic activity in cells of the muscular-intestinal plexus of the esophagus, duodenum and rectum has been studied cytophotometrically. Glucose-6-phosphatase dehydrogenase, NADPh-dehydrogenase, acid phosphatase, alkaline phosphatase (APh), monoamine oxidase, acetylcholine esterase (AChE) have been revealed in 19-20-day-old embryos, in 1-, 21-, 30-day-old rats and in mature rats. A high APh activity is revealed in all the groups studied; in the process of development the duodenum legs behind, concerning AChE activity. This demonstrates certain peculiarities in its mediator regime. Evidently, dyskinetic phenomena in the middle part of the gastrointestinal tract in children are connected with this. Enzymatic activity, connected with general metabolic processes, demonstrates that differentiation develops towards decreasing amount of cellular types, while the enzymes, that are connected with metabolism of the mediators, demonstrate an increasing variability of cells in the process of their differentiation.
