Feron, V.J. (author), Kruysse, A. (author), Til, H.P. (author), Centraal Instituut voor Voedingsonderzoek TNO (author)Wistar rats were exposed to atmospheres containing 0 (control) or 5000 ppm vinyl chloride monomer (VCM), 7 h/day, 5 days/week, for a period of 52 weeks. After 4, 13, 26 and 52 weeks each time 10 rats/sex/group were killed and subjected to extensive examinations. The present paper deals with growth, mortality, haematology, clinical chemistry and...article 1979

(author), Visser, R.P.L.S. (author), Medisch Biologisch Laboratorium TNO (author)Three new nonquaternary oximes have been evaluated with respect to their antidotal activities against organophosphate poisoning. The oximes 1,2,3-thiadiazole-5-carboxaldoxime (1, pKa = 7.6), 2-methyl-1,3,4-thiadiazole-5-carboxaldoxime (2, pKa = 8.4), and 3-methyl-1,2,4-thiadiazole-5-carboxaldoxime (3, pKa = 7.0) were prepared in yields of 56, 24...article 1979

(author), Centraal Instituut voor Voedingsonderzoek TNO (author)The subacute inhalation toxicity of butenolide was examined in hamsters by repeated exposure of 4 groups of 10 males and 10 females to butenolide vapour at concentrations of 0, 5.4, 25 and 130 ppm respectively (6 h/day, 5 days/week) for a period of 13 weeks. The effects found at 130 ppm included eye irritation, salivation, nasal discharge,...article 1979

Feron, V.J. (author), Kruysse, A. (author), Til, H.P. (author), Immel, H.R. (author), Centraal instituut voor voedingsonderzoek TNO (author)The subacute inhalation toxicity of acrolein was examined in 4 groups of 20 hamsters, 12 rats and 4 rabbits each, exposed repeatedly to acrolein vapour at concentrations of 0, 0.4, 1.4 and 4.9 ppm (6 hr/day, 5 days/week) for a 13-week period. The most important effects found at the highest level included mortality in rats, ocular and nasal...article 1978

Kruysse, A. (author), Feron, V.J. (author), Immel, H.R. (author), Centraal instituut voor voedingsonderzoek TNO (author)The inhalation toxicity of peroxyacetyl nitrate (PAN) was examined in acute (single exposure), subacute (4-wk repeated exposure) and subchronic (13-wk repeated exposure) studies in rats. The 4-hr LC50 was found to be 95 ppm. In the 4-wk study rats were exposed to 0, 0.9, 4.1 or 11.8 ppm PAN vapor for 6 hr/day, 5 days/wk. Exposure to 11.8 ppm...article 1977

(author), Centraal Instituut voor Voedingsonderzoek TNO (author)To find out whether alkali treated proteins possess nephrotoxic properties, feeding studies were conducted with drastically treated soybean protein and casein, and also with lysinoalanine (LAL), the amino acid known to be formed in proteins subjected to high pH at an elevated temperature. The feeding of synthesized LAL to rats at dietary levels...article 1976
