AB  - The rheological behaviour of deoxyribonucleoprotein (DNP) in high ionic strength 
      solutions (0,7 M NaCl) is indicative of the presence, in these systems, of 
      linearly ordered DNP microstructures, which are reversibly destroyed by 
      mechanical influences. The examination of the models of spatial network which are 
      capable of providing the limit of fluidity for low concentrated DNP solutions 
      permits to abandon the model of bound tracery network. The existence of 
      interrupted network is proposed which is formed by fixation of microstructures in 
      the secondary potential minimum without direct contact. It is concluded that DNP 
      is able to organize liquid-cristalline structures with linear orientation of the 
      axes of microstructural elements. The possibility of superhelical organization of 
      such microstructures is not excluded. The long-range surface forces take part in 
      stabilization of DNP-microstructures.
