Schrikker, A.C.M. (author), de Vries, W.R. (author), Zwart, A. (author), Luijendijk, S.C.M. (author)We have investigated the slope of the alveolar plateau for inert tracer gases that were washed out from mixed venous blood. Two pairs of tracer gases were used (He, SFe) and (C2H2, Freon 22). The gases of each pair share almost the same blood-gas partition coefïicient but they have different diffusive properties in the gas phase. The experiments...article 1989

Zwart, A. (author), Arts, J.H.E. (author), ten Berge, W.F. (author), Appelman, L.M. (author)A new design for acute inhalation toxicity testing was evaluated and compared with results obtained according to OECD guideline 403. The new design consists of a range-finding test, which is compatible with a conventional limit test, and can be followed by determination of a concentration-time-mortality relationship, enabling calculation of LC50...article 1992

In vitro binding of estrogens by dietary fiber and the in vivo apparent digestibility tested in pigsArts, C.J.M. (author), Govers, C.A.R.L. (author), van den Berg, H. (author), Wolters, M.G.E. (author), van Leeuwen, P. (author), Thijsen, J.H. (author), Instituut CIVO-Toxicologie en Voeding TNO (author)Within the framework of experiments related to the association between dietary fiber and breast cancer an in vitro test system was used to study the binding of estrogens to various fibers (e.g. cholestyramin, lignin and cellulose) and fiber sources (e.g. wheat bran, cereals, seeds and legumes). Furthermore, the in vivo apparent digestibility of...article 1991

(author), Hoofdgroep Maatschappelijke Technologie TNO (author)The sensitivity of different parameters for the determination of lung injury caused by nitrogen dioxide (NO2) was investigated. Male rats were exposed to concentrations of 0, 4, 10 or 25 ppm NO2 for 6 h/day, for 7, 14 or 21 days. Histopathology of the nasal cavity, larynx, trachea and lungs was compared with the changes in macrophage function...article 1988

Rodenburg, R.J.T. (author), Ganga, A. (author), van Lent, P.L.E.M. (author), van de Putte, L.B.A. (author), van Venrooij, W.J. (author)Objective. Sulfasalazine (SSZ) is a commonly used drug in the treatment of inflammatory diseases such as rheumatoid arthritis and Crohn's disease. In both diseases, the proinflammatory cytokine tumor necrosis factor α (TNFα) plays a prominent role. In these studies, we investigated the mechanism by which SSZ inhibits TNFα expression in...article 2000
