[Projections of the gastrointestinal tract organs on afferent ganglions of the vagus nerve in rats].
Experiments were carried in 42 mature white male rats. We investigated into the projections of different organs of gastrointestinal tract on afferent neurones of ganglia of the vagus nerve in white rats. Horseradish peroxidase-conjugated lectins were used as a tracer. We investigated into metric parameters (diameter of an equivalent circle) and shape parameters (circular factor of the shape) of marked neurocytes using a method of computer video-analysis. To evaluate reliability of the received data, methods of non-parametric statistics were used. It was determined that the largest neurocytes in afferent ganglions are involved in innervation of the root of the long and ileocecal angle, the smallest ones--in innervation of a cervical department of esophagus and liver. The viscero- and somatosensory neurocytes in caudal ganglion of vagus nerve involved in innervation of different organs in white rat, are characterized by selectivity of the shape and by metric parameters.
