Toxicological assessment of magnesium oxide nanoparticles in HT29 intestinal cellsFühner-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
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
Aspect ratio has no effect on genotoxicity of multi-wall carbon nanotubesFühner-Wieland's Sammlung von Vergiftungsfällen - Tập 85 - Trang 775-786 - 2010

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 ratsFühner-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 skinFühner-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
Neurobehavioral performance in volunteers after inhalation of white spirits with high and low aromatic contentFühner-Wieland's Sammlung von Vergiftungsfällen - Tập 88 - Trang 1127-1140 - 2014
S. A. Juran, G. Johanson, L. Ernstgård, A. Iregren, C. van Thriel
The content of aromatic hydrocarbons in solvent mixtures, such as white spirits (WS), has been assumed a major contributor to the neurotoxic effects of these compounds. Hence, dearomatized WS have been introduced to the market rapidly in the last decade. Studies investigating other aromatic hydrocarbons (toluene) and animal models have supported the aforementioned assumption, but the current study...... hiện toàn bộ
