[Adrenergic and cholinergic innervation of the kidneys in several mammals].

In dogs and some other mammals, the major neuronal sources for plexus renalis, distribution, architectonics and topographic interrelations of intrarenal neuronal plexus were studied. Adrenergic nerve fibres were revealed by the luminiscent histochemical technique; cholinergic--by the cytochemical method for acetylcholinesterase identification. Peculiar patterns of the intrarenal adrenergic and cholinergic neuronal plexus around the preglomerular arterial bed (main periarterial and adventitial plexus), innervation of efferent arterrioles and vasa recta are described. The system of fine varicous fibres forming neuronal plexus in the marginal zones of the connective tissue and at the cortico-medullar border, that of cortical tubes, venous, pelvic and fibrous capsule innervation of the organ are considered. Some species differences are discovered. The data obtained are compared with those from literature and discussed in terms of functional neuromorphology.
