[Morphologic findings after intracerebral administration of an alcoholic prolamine solution]

Morphological studies were performed after intracerebral injection of Ethibloc (E.), an alcoholic prolamine solution, to prove the usefulness of E. as a drug depot in the local chemotherapy of brain gliomas. Organisation of E. starts 2-3 weeks after injection, but remains incomplete even 24 weeks later. This depot cannot be removed in case of diminished drug concentration because of the extremely close connection with the adjacent brain tissue. Further repeated injection of drug into the E. depot cannot reach the tumours periphery because of the surrounding glial scar and connective tissue.
