To examine the validity of a modified lymphocyte transformation test for evaluating contact hypersensitivity from weak sensitizers, guinea pigs were sensitized with formaldehyde (F) or tetramethylthiuram monosulfide (TMTM) using the maximization test procedure. Lymph node cells from the animals were
In recent years data have accumulated regarding genotoxic properties of dithiocarbamic acid derivatives. The results from the present work indicate that the mutagenicity of these compounds depends on an indirect effect via oxygen radicals. Mutagenicity of tetramethylthiuram disulfide ( TMTD
The epoxide hydrolase (EH) activity in the liver of adult female Wistar rats significantly increased 18 h after the administration by gavage of tetramethyl thiuramdisulfide (TMTD, 1 mmol/kg) or tetramethyl thiurammonosulfide (TMTM, 2 mmol/kg). No increase was observed 5 h
