[Surface properties of cerebrospinal fluid cells following intrathecal methotrexate treatment].

Authors first in the literature described the surface profile of lymphocytes, plasma cells, phagocytes and malignant lymphoblasts of the liquor after intrathecal Methorexat therapy (i.thec.MTX). After prolonged treatment with MTX the mentioned cells were examined by SEM. The surface of the plasma cells and storage cells was found to be normal. Various stages of the phagocytosis could be observed. On the other hand the majority of lymphoblasts of leukaemic origin after the first administration of i.thec.MTX revealed damaged cell surfaces.
