[Distribution of adrenoreceptors in the microcirculatory components of the circulatory bed of the kidney in the cat].
Topography of alpha- and beta-adrenoreceptors and their significance for smooth muscle cells of various links of the arterial division of the cat kidney blood channel were studied by means of alpha- and beta-adreno-stimulators and adrenoblockers administration under the control of general arterial pressure. The initial divisions of the major arteries and arterioles and their primary branches of the kidney fibrous capsule, distal divisions of afferent glomerulus vessels and their corresponding precapillary arterioles as well as the initial divisions of the straight arterioles of the kidney substance medullaris were shown to contain beta-adrenoreceptors. Alpha-adrenoreceptors are present in all other extra-parenchymatous and parenchymatous arteries and arterioles.
