    Notes: Abstract Sequential morphological changes in murine liver induced by cyclochlorotine (CC), a secondary metabolite of Pencicillium islandicum were investigated by transmission electron microscopy and scanning electron microscopy. Within 15 min after the administration of CC there was a marked dilatation of Disse's space around the portal triads, and the exudates then poured out into the space which was formed by the invagination of the hepatocyte plasma membrane. Shortly after the invagination was completed, the connection between Disse's space and the invaginated space was pinched off, so that this space became a membrane-bound vacuole. After dehydration, the vacuoles became granular. The liver injuries induced by CC were influenced by various pretreatments. The results indicate that drug-metabolizing systems mediated by cytochrome p-450 in the hepatocytes may play an important role in the hepatotoxicity of CC.
