Coexposure to small, noninjurious doses of the pyrrolizidine alkaloid phytotoxin monocrotaline (MCT) and bacterial lipopolysaccharide (LPS) results in synergistic hepatotoxicity. Both centrilobular and midzonal liver lesions occur and are similar to those seen from large, toxic doses of MCT and LPS, respectively. The nature of the lesions in vivo and(More)
Synergistic liver injury develops in Sprague-Dawley rats from administration of a small, noninjurious dose (7.4 x 10(6) EU/kg) of bacterial lipopolysaccharide (LPS) given 4 h after a nontoxic dose (100 mg/kg) of the pyrrolizidine alkaloid, monocrotaline (MCT). Previous studies demonstrated that liver injury is mediated through inflammatory factors, such as(More)
