Rats were killed at various time-intervals up to 48 hr after a single large dose of paracetamol (3 g per kg) and their livers examined by light and electron microscopy. In general, this revealed glycogen depletion, loss of ribosomes, and cytoplasmic matrix swelling commencing 3-6 hr after administration which in centrilobular hepatocytes progressed to frank coagulative necrosis at 12-24 hr. Midzonal cells showed more prominent aqueous swelling with besiculation of the endoplasmic reticulum, and in some cells, gross hydropic vacuolation.
