[Morphometric analysis of the state of the intraorganic blood vessels].
A method for reconstruction of intraorganic vessels sections visible in histological sections into the sections of regular round vessels with preservation of real area of their wall and lumen is presented. A new characteristic of the vessel state is introduced -- degree of elastic membrane twistiness. Changes in various branches of the dog pulmonary artery at burns and at simultaneous bilateral resection of 58% lung tissue are taken as an example in order to demonstrate that at a complex analysis of the vascular wall area/the lumen area ratio, taking into account the degree of elastic membrane twistiness, it is possible to differentiate functional changes of the vascular tonus from the organic ones.
