[Responses of isolated arterial segment to a slow changing of perfusion pressure in it].
In in vitro experiments, segments of the Wistar rat tail artery's segments were perfused with the Krebs-Henselite solution. Increase of the perfusion pressure with the velocity of 5 mm Hg/min from 0 to 110 mm Hg with its subsequent drop with the same velocity down to zero showed that, within the limits of the above interval of values of the intravascular pressure, existed a range where two values of the artery diameter corresponded to each established value of the pressure. The data obtained prompt a further deciphering of mechanisms of the mechanogenic regulation of the blood vessels.
