[Clinical picture and several histochemical changes in the brain in cerebral rheumovasculitis].

A clinical study of 70 patients with cerebral rheumovasculitis permitted the author to distinguish 3 forms of the disease: with a diffuse, mild focal and crude focal neorological symptomatology. Their dependence upon the somatical signs is demonstrated, a successional development of nervous system lesions, treatment and its effectiveness. The histochemical studies in different brain areas in patients with crude focal neorological symptomatology demonstrated allergic, metabolic and inflammatory changes in the vascular walls, accompanied by hemodynamical changes and deep dystrophy of the neurons and nervous fibres, as well as productive reaction of the astrocytes, oligodendrocytes and microglial elements.
