  Background: Our aim was to investigate the effect of intra-oesophageal acetaminophen instillation on the selected antioxidative enzymes activity: superoxide dismutase isoenzymes (MnSOD, Cu/ZnSOD), glutathione peroxidase (GPX), glutathione-S-transferase (GST), glutathione reductase (GR) and lipid peroxidation in rat liver after 4, 8 and 12 weeks of exposure. Material and methods: Male Wistar FL strain rats weighing 150-160 g were treated with paracetamol by intra- oesophageal instillation at a dose of 2.4 g/kg b.w every day up to 12 weeks. During the whole experiment rats were kept in a night-and-day’s cycle lasting twelve hours, with standard feed ad libitum . Rats were sacrificed after 4, 8 and 12 weeks of the study. The collected tissue liver was homogenized and the above mentioned enzymes were determined in the supernatants. Results: The current study revealed the presence of.. View More»
