Strongyloidiasis is a persistent human parasitic infection caused by the intestinal nematode, Strongyloides stercoralis. The parasite has a world-wide distribution, particularly in tropical and subtropical regions with poor sanitary conditions. Since individuals with strongyloidiasis are typically asymptomatic, the infection can
The aromatic amine benzidine (BZ) has produced various tumors, including liver tumors, in mice, rats and hamsters. BZ forms DNA adducts in rodent liver, and it is positive in most genotoxicity tests. Only bladder tumors are produced in dogs and
Drug metabolism and disposition: the biological fate of chemicals, 26(9), 856-859 (1998-09-12)
Workers exposed to high levels of benzidine have a 100-fold increased incidence of bladder cancer. This review evaluates the overall metabolism of benzidine to determine pathways important to initiation of bladder cancer. Upon incubation of benzidine with liver slices from
Benzidine oxidative activation may proceed by peroxidase-catalyzed one-electron oxidation via free radical intermediates, or by N-acetylation followed by monooxygenase-catalyzed N-hydroxylation. The peroxidase route has been examined by using horseradish peroxidase or prostaglandin H synthase in vitro. In the presence of
Benzidine, an odorless, white to slightly reddish-white crystalline organic compound, is an environmental contaminant that has been identified at about 30 National Priorities List (NPL) hazardous waste sites in the United States. In the environment, it is usually found attached
