Electron microscopy in human hepatic encephalopathy

Summary Electron microscopic post mortem examination of the lenticular nuclei of two human cases who died in hepatogenic coma is reported. Lesions were found to be swelling and vacuolation of astrocytes. In addition an excess of lipofuscin and lipid like substances were present in the same cells. No changes were found in myelinated fibres, neurons and small blood vessels.This study was supported by CIC 80 from Universidad de Concepción.
