Paracetamol-induced hepatic necrosis is the most common form of toxic liver injury experienced in clinical practice in the UK and USA. Recently, reports have described prevention of hepatic necrosis, induced by other hepato-toxins, by inhibiting tumour necrosis factor alpha (TNFalpha). The aim of th

Abstract
HEPATIC necrosis resulting from massive overdosage with paracetamol (Nβacetylβpβaminophenol, acetaminophen, APAP) was first reported in rats by Boyd and Bereczky in 1966. A report of this complication in man soon followed (Davidson and Eastham, 1966) and a total of 12 such cases have now been reported (Thomson and Prescott, 1966; Maclean et at., 1968; Pimstone and Uys, 1968; Rose, 1969; Toghill et al., 1969). Whilst Boyd and Bereczky were mainly concerned with acute oral toxicity, they summarised the histopathological findings in a large number of tissues and gave a brief description of the histological changes in the liver. There has not been a detailed histopathological study of paracetamolβinduced liver necrosis, nor has the natural course of the lesion been adequately described. The main objective of the present study was to provide such information by examining the changes in the livers of rats killed at various intervals after administration of a single large dose of paracetamol.
