We studies toxic effects of Sarcocystis hirsuta cyst extract in mice. Degenerative changes were found in the mice received fresh, frozen and heated S. hirsuta cyst extract. There were increases in the levels of serum aspartate aminotransferase and alanine aminotransferase (AST and ALT) as well as hepatic and brain malondialdehyde (MDA) levels with a concomitant decrease in catalase (CAT) and superoxide dismutase (SOD) activities of mice received fresh and frozen S. hirsuta extracts. Gavage feeding of heated S. hirsuta cyst extract had no effects on liver enzymes and brain MDA content, but increased liver MDA. Mice in this group showed reduced CAT and SOD activities as well as increased hepatic MDA compared to control group. These findings indicate that the extract of S. hirsuta cyst can induce oxidative stress and hepatic injury even after heating.
