Changes in glucidic radicals in contused human brains.

Changes in carbohydrate metabolism in brain injury and the involvement of numerous glycoproteins in the subsequent restoration phenomena orientated this paper towards reporting on glucidic radical distribution in postinjured brain tissue. Samples from nine patients suffering severe head injuries and three matched controls were studied. Autopsies were performed up to 24 h postmortem; brains were fixed in formalin and samples were taken from contusional, pericontusional and different brain regions including the anterior cingulum and corpus callosum, parasagittal gyrus, putamen, hippocampus and opercular areas embedded in paraffin.
