[Histochemical study of the innervation of the gastric veins in the cat].
By means of Koelle's and Glenner's methods, functional nature of the neural apparatuses in the left and right cat gastric veins has been studied. The parasympathetic neural apparatus is presented by cholinergic neural fibres running both in the plexus-forming fasciculi and as single fibres. The neural plexus branches penetrate into the external and medial venous tunics and make anastomoses forming multiple loops of various size and length dependent on depth of their occurrence. The neural trunkets of the cholinergic fibres accompany the own blood vessels of the veins studied. Acetylcholinesterase activity in different conductors and within the length of the same fibre is not the same; this demonstrates certain fluctuations in functional intensity of the cholinergic apparatus. The sympathetic neural apparatus is presented by the monoaminergic fibres running in plexus together with the cholinergic ones.
