A CONTRIBUTION TO THE STUDY OF HUMAN NEUROGLIA

The results and conclusions of the above investigation are: 1. The term glio-sarcoma should be dropped, as unscientific and misleading in its significance. 2. The problems regarding neuroglia demand varied methods for their adequate study. 3. With all the means at our command, the absolute determination of the relation of cells and fibres in individual cases remains difficult and at times impossible. 4. No criterion has yet been offered to determine a fundamental distinction between glioma and sarcoma (Stroebe); and secondly, between glioma and so-called gliosis (Weigert). 5. The development of neuroglia in all probability is from cells with protoplasmic processes to cells with differentiated and independent fibres. 6. Herein lies a possible reconciliation of the conflicting views concerning the ultimate structure of human neuroglia.
