TNO Prins Maurits Laboratorium (author), Langenberg, J.P. (author), de Jong, L.P.A. (author), Benschop, H.P. (author)Several p-nitrophenyl phosphoramidates with the general formula RO(NH2)P(O)OC6H4-p-NO2, in which R = CH2CH3, CH2CH2F, CH2CHF2, CH2CF3, CH2CH2CH2CH3, and CH2CH2Cl, as well as (NH2)2P(O)OC6H4-p-NO2 were administered intravenously to guinea pigs as pretreatment compounds for protection against the lethal effects of 1,2,2-trimethylpropyl...article 1996

(author), Instituut CIVO-Toxicologie en Voeding TNO (author)In this study a polymorphism in the conjugating activity of human erythrocyte cytosol towards the dihaloethane, ethylene dibromide (EDB; 1,2-dibromoethane) was found. Two out of 12 human erythrocyte cytosols did not catalyze the formation of glutathione (GSH) conjugates of [1,2-14C]EDB. Ten cytosols formed the S,S'-ethylenebis(GSH) conjugate at...article 1995

van Raaij, J.A.G.M. (author), Kaptein, E. (author), Visser, T.J. (author), van den Berg, K.J. (author), Medisch Biologisch Laboratorium TNO (author)Metabolism of thyroid hormones was investigated in WAG/MBL rats that had been exposed to hexachlorobenzene (HCB). Serum thyroxine (T4) levels were lowered by 35.5%, whereas triiodothyronine (T3) levels were not changed. Bile flow, as well as T4 excretion in bile were increased by HCB treatment. Analysis of bile by HPLC revealed a more than 3...article 1993

van den Berg, K.J. (author), van Raaij, J.A.G.M. (author), Bragt, P.C. (author), Notten, W.R.F. (author), Medisch Biologisch Laboratorium TNO (author)Previous results in experimental systems have suggested that hydroxylated PCBs may decrease thyroid hormone levels through associative interaction with transthyretin. In the present paper it was investigated whether this property was also shared by various industrial chemicals, mainly pesticides. In total, 65 compounds from 12 chemical groups...article 1991
