title: [Functional characteristics of Rana temporaria arteries and veins with different densities and neuromediator properties of vasomotor innervation].
abstract: Pharmacological studies have been made of frog's arteries and veins with different density and transmitter nature of their vasomotor innervation. It was found that the difference in vasomotor innervation of the blood vessels is related to the level of their maximal contractile response. The higher the adrenergic innervation, the higher the response to exogeneous catecholamines. The higher the cholinergic innervation, the higher the response to acetylcholine. Vasomotor innervation affects the sensitivity of the blood vessels, however catecholamine sensitivity is also observed in non-innervated vascular smooth muscle cells. alpha-Adrenoreceptors were found both in the innervated and non-innervated vessels, whereas beta-adrenoreceptors are present only in the innervated ones.
