[The nature of the thermomechanical reactions of the vascular wall].

Thermosensitivity of the guinea pig aorta wall stretched to 1.05-1.40 of its initial length, was shown to completely depend on the connective tissue: the thermomechanical responses of the stretched aorta entailed changes in its stiffness typical for an agonist-induced vessel tissue contraction. The connective tissue component of the mechanical response of the vascular wall seems to have a universal character.
