Sixty-five malignant gliomas (astrocytomas grade 3 and 4 and glioblastomas) were examined by means of immunoperoxidase staining on frozen tissue using various monoclonal antibodies directed against macrophages, lymphocytes and natural killer cells. Depending on the antibody used, the presence of macrophages in tumours ranged from 85%-100%. Many of the(More)
The distributions of 8 peptides were studied in the 4 major segmental levels (cervical, thoracic, lumbar, sacral) of the spinal cord in 52 neurologically normal cases. Similar regions from 36 cases of motor neurone disease (MND) were compared using the same procedures to determine possible changes in the distribution of peptides in areas associated with(More)
The antigenic characteristics of 20 primary cerebral lymphomas have been defined by their reactivity with a panel of monoclonal antibodies recognizing differentiation antigens of lymphocytes and other cell types. In 7 out of 20 cases (35%), immunohistological results were diagnostically crucial and this approach appeared almost to double the detection rate(More)
