[Dynamics of lymph node function in disordered innervation]

A mechanotron 6MX1C was used to study lymphodynamic indices of the dog popliteal lymph nodes after cutting the ischiatic and femoral nerves in the left limb at 1 week, 3 and 5 months. The lymph nodes of the contralateral limb and the lymph nodes from intact dogs were used as controls. It has been demonstrated that denervation causes acceleration of the periods of the filling and emptying of the lymph nodes both in the denervated and contralateral limbs as compared with the initial period. The amplitude of fluctuations under maximal filling of the lymph nodes decreases significantly at the long-term postoperative periods. The lymphodynamic changes seem to be determined by pathomorphological alterations in lymph node tissues.
