[Comparative ultrastructure of human gliomas and experimental gliomas induced by Rous sarcoma virus (RSV) (author's transl)].

A brief review of earlier results concerning the ultrastructure of 20 gliomas induced by intracerebral inoculation of Rous sarcoma virus in the dog emphasizes the similarity of certain canine and human histological types. Since no sign of the viral induction is recognizable for certain in the experimental tumors and since the large size of the animal authorizes the use of the same radiological detection techniques as in Man these viral induced tumors represent a remarkable experimental model.
