[Lesions of the central and peripheral nervous systems in rheumatoid arthritis].
Using morhological, neurohistological and histochemical methods the author studied different areas and anatomical structures of the central and peripheral somatic and vegetative nervous system in 4 patients who had died during different periods of rheumatoid arthritis at the age of 27, 48, 51, and 60. The studies demonstrated symptoms of disorganization of the connective tissue in the sheaths and walls of vessels (mainly in the microcirculatory bed), lymphoid histocyte infiltrates, rheumatoid nodules and nonspecific changes of neurocytes and conductors. The paper contains a description of the main form of lesions in rheumatoid, arthritis of the nervous system.
