Anatomic pairing of afferent arterioles and renin cell distribution in rat kidneys [Text] / Daniel Casellas [et al.] // Amer. J. Physiol. - 1994. - Vol. 267, N 6. - PF931-F936 . - ISSN 0002-9513
Перевод заглавия: Анатомическое сплетение афферентных артериол (АА) и клеточное распределение ренина в почках крыс
Аннотация: Studies were conducted in rat. mouse, rabbit, and human renal vasculatures obtained by an HCl maceretion-microdissection technique to document the extent of AA connectivity. In rat kidneys, we assessed the possibility for a slow component of internephron coupling, as reflected by arteriolar renin cell distribution after specific immunostaining for renin. In the four species examined, 51% (human) to 60% (mouse) of total AA populations were organized as vascular units consisting of mostly two AA sharing a common origin and a connecting arterial segment. In rat AA pairs, branch lengths were significantly correlated, suggesting coordinated arteriolar growth. The sum of AA branch lengths averaged 278'+-'6 'мю'm. Rat arteriolar renin status, ranging from no renin cells to renin-recruited midafferent arterioles, distributed in a significantly nonrandom fashion within AA pairs, and 52% of the pairs had equal renin status. Hence, AA pairing is a consistent anatomic characteristic of mammalian kidneys and may constitute an optimal vascular design for hemodynamic as well as endocrine interactions.
