title: Early sterile autopsy in etiological studies on multiple sclerosis.
abstract: The clinical findings and course in the first 2 cases of multiple sclerosis are described, in whom it was possible to isolate a virus from brain tissue by early sterile autopsy and fusion technique. It is noteworthy that in one of these cases multiple sclerosis probably occurred in female members of the family through three consecutive generations. A report is made on an additional case, in which no virus could be isolated, but in which electron microscopic studies showed two types of virus particles: nucleocapsid-like structures and particles identical in form and size with papova virus. Electron microscopic findings and attempts to cultivate a virus in multiple sclerosis published by other authors are discussed. It is pointed out, that the results described provide as yet no proof for the viral etiology of multiple sclerosis. They support the hypothesis, however, that a virus may play an essential role in the etiology and/or pathogenesis of this disease. Problems in relation to brain autopsy in multiple sclerosis are discussed. Early sterile autopsy is considered the most practicable possibility for obtaining tissue material for culturing and for ultrastructural studies in multiple sclerosis.
