[The endotheliocytes of the lymphatic capillary and their motor activity].

Endotheliocytes of lymphatic capillaries of different configuration were studied in total preparations of central tendon of diaphragm in rabbits. Between different cell types there are transitional forms. Argyrophilic structures in the form of loops, hooks and rods, located inside the endotheliocytes but linked with intercellular borders were described. The data obtained allowed to conclude the presence of motor activity of lymphatic capillaries endotheliocytes associated with change of their shape and border length along the cell perimeter. Endotheliocyte motor activity sharply increases in aseptic inflammation. Different endotheliocyte configuration and their perimeter length are dependent on the lymphatic capillaries resorptive activity.
