Toxicological assessment of magnesium oxide nanoparticles in HT29 intestinal cells
Fühner-Wieland's Sammlung von Vergiftungsfällen - Tập 93 - Trang 1491-1500 - 2019
Anna Mittag, Thomas Schneider, Martin Westermann, Michael Glei
Nanoparticles (NPs) are increasingly used in different consumer-related areas, for instance in food packaging or as additives, because of their enormous potential. Magnesium oxide (MgO) is an EU-approved food additive (E number 530). It is commonly used as a drying agent for powdered foods, for colour retention or as a food supplement. There are no consistent results regarding the effects of oral ...... hiện toàn bộ
Reactivators of organophosphate-inhibited cholinesterase
Fühner-Wieland's Sammlung von Vergiftungsfällen - Tập 49 - Trang 285-291 - 1982
Vjera Deljac, Matej Maksimović, Ljiljana Radović, Dušanka Rakin, Verica Markov, Ivo Bregovec, Zlatko Binenfeld
Eleven isomeric phenylhydroxymethyl and cyclohexylhydroxymethyl derivatives of 1-(2-hydroxyiminomethyl-1-pyridinio)-3-(1-pyridinio)-2-oxapropane diiodide and 1-(4-hydroxyiminomethyl-1-pyridinio)-3-(1-pyridinio)-2-oxapropane diiodide were prepared and characterized by spectroscopic methods and pKa values. The inhibitory power (I50) of the investigated oximes was determined on purified bovine erythr...... hiện toàn bộ
Evaluation of a testicular sperm head counting technique using rats exposed to dimethoxyethyl phthalate (DMEP), glycerolα-monochlorohydrin (GMCH), epichlorohydrin (ECH), formaldehyde (FA), or methyl methanesulphonate (MMS)
Fühner-Wieland's Sammlung von Vergiftungsfällen - Tập 53 - Trang 71-78 - 1983
S. L. Cassidy, K. M. Dix, T. Jenkins
Single dosages of DMEP (1,000–2,000 mg/kg), GMCH (50 mg/kg), ECH (25 and 50 mg/kg), FA (100 and 200 mg/kg), and MMS (100–400 mg/kg) were administered orally to 10 week old male Wistar rats. The rats were necropsied on the 11th day following dosing. The testes were weighed, homogenised and sonicated; numbers of sperm heads (total and abnormal) were counted and percentage sperm head abnormalities we...... hiện toàn bộ

Cytotoxic effects of hexavalent chromium in cultured murine macrophages
Fühner-Wieland's Sammlung von Vergiftungsfällen - Tập 66 - Trang 347-353 - 1992
Margot Martiny Christensen, Erik Ernst, Svend Ellermann-Eriksen
The in vitro effect of hexavalent chromium (CrVI) on mouse peritoneal macrophages was investigated. Our results demonstrate the existence of a threshold concentration of 2.5 ΜM of CrVI above which chromium affects the viability of macrophages in a concentration dependent manner. Morphological changes were seen with increasing concentrations of chromium. Evidence is presented that protein productio...... hiện toàn bộ
The comparative acute mammalian toxicity of 1-chloroacetophenone (CN) and 2-chlorobenzylidene malononitrile (CS)
Fühner-Wieland's Sammlung von Vergiftungsfällen - - 1978
B. Ballantyne, D. W. Swanston
The comparative acute toxicity of two peripheral sensory irritant materials, 1-chloroacetophenone (CN) and 2-chlorobenzylidene malononitrile (CS), has been investigated in several species of small mammal using solutions in polyethylene glycol 300 for intravenous, intraperitoneal and oral administration, and as pure aerosols for inhalation exposure. Additionally, the comparative potency for inducin...... hiện toàn bộ
Aspect ratio has no effect on genotoxicity of multi-wall carbon nanotubes
Fühner-Wieland's Sammlung von Vergiftungsfällen - Tập 85 - Trang 775-786 - 2010
Jin Sik Kim, Kyu Lee, Young Hee Lee, Hyun Sun Cho, Ki Heon Kim, Kyung Hee Choi, Sang Hee Lee, Kyung Seuk Song, Chang Soo Kang, Il Je Yu
Carbon nanotubes (CNTs) have specific physico-chemical and electrical properties that are useful for telecommunications, medicine, materials, manufacturing processes and the environmental and energy sectors. Yet, despite their many advantages, it is also important to determine whether CNTs may represent a hazard to the environment and human health. Like asbestos, the aspect ratio (length:diameter)...... hiện toàn bộ
Renal effects of in utero exposure to mercuric chloride in rats
Fühner-Wieland's Sammlung von Vergiftungsfällen - Tập 66 - Trang 508-513 - 1992
A. M. Bernard, C. Collette, R. Lauwerys
The transplacental nephrotoxicity of mercuric chloride has been studied in female Sprague-Dawley rats. Mercuric chloride was injected s. c. to rats at the dose of 1 mg/kg during the last 8 gestational days or the whole pregnancy. Both mothers and newborns developed a transient renal dysfunction resulting in an increased urinary excretion of beta2-microglobulin and albumin. In mothers and their fem...... hiện toàn bộ

In vitro absorption of some chlorinated paraffins through human skin
Fühner-Wieland's Sammlung von Vergiftungsfällen - Tập 63 - Trang 425-426 - 1989
Robert C. Scott
The in vitro absorption of chlorinated paraffins, Cereclor S52 and Cereclor 56L (present in a cutting fluid), has been measured through human skin. During 56 h continuous skin contact no Cereclor S52 was detected to have been absorbed and only a very slow rate of Cereclor 56L absorption (mean rate, 0.04 μg/cm/h) was measured. This rate was only apparent after more than 7 h continuous skin contact....... hiện toàn bộ
