title: [Neurohistochemical and ultrastructural study of the adrenergic innervation of the wall of the rat posterior vena cava during chronic venous hypertension caused by experimental oleothorax].
abstract: Chronic venous hypertension in rats was provoked by injection of polymethyloxane into the pleural cavity. Hypertrophy of muscular tissue was accompanied by reconstitution of adrenergic nervous structures. In the early stages (up to 40 days), the changes in the latter are reactive in nature: first there occurs a weakening of luminescence, rare-fraction of the network and then "hyperneuria". Pulmonary heart formation was followed by marked hypertrophy of SMC, increased density of adrenergic fibers, convergence of SMC and nerve terminals (synapse formation).
