[Interconversion of spiral D- and L-enantiomorphs of vascular muscles].
Possibilities of mutual transformation of the right coiled enantiomorphs of the smooth muscle elements in the vascular walls into the left ones and vice versa have been studied. The circular smooth muscle cells make the base of similar transformation. They are coiled in one plane and connected by their ends with longitudinally situating cells. When the longitudinal cells contractile at both sides, the circular cells, stretching along the longitudinal axis of the vessel, arrange on the cylinder surface in the form of the right or left spirals. Their transformation into one another is reached by means of contracting the profile element at one or other side of the point where the circular element is fixed. The common regularity of this interreorganization is transition across the right-left form of the Archimedean spiral. Similar enantiomorphism of mutual reorganization is considered in the model and determined as a reaction to gravitational-heat effect, contributing to better movement of the liquid biological medium along the blood vessel canals.
