Data describing the biokinetics of radionuclides after contamination come mainly from experimental acute exposures of laboratory animals and follow-up of incidental exposures of humans. These data were compiled to form reference models that could be used for dose calculation in humans. In case of protracted exposure, the same models are applied, assuming(More)
Uranium uptake can occur accidentally by inhalation, ingestion, injection, or absorption through intact or wounded skin. Intact or wounded skin routes of absorption of uranium have received little attention. The aims of our work were (1) to evaluate the influence of the type of wound contamination on the short term distribution and excretion of uranium in(More)
The aim of this work is to assess in vivo in a hairless rat model, the percutaneous diffusion of uranium through intact or wounded rat skin. Six types of wounds were simulated by excoriation and burns with 10 N HF, 2, 5 and 14 N HNO3 and 10 N NaOH on anaesthetised hairless rats. Percutaneous penetration through wounded skin towards blood and subsequent(More)
At the present time, the International Commission on Radiological Protection (ICRP) has not published any model concerning internal radioactive contamination by uptake from wounds. The aims of our work were to determine the time available to treat contamination of intact or wounded skin before a significant uptake of uranium occurred and to evaluate the(More)
Lambs originating from Suffolk, Milksheep and Texel crossbreeds were injected with saline, 500 micrograms ovine prolactin or 500 micrograms ovine GH within 30 min of parturition (n = 10). Birth weight was negatively correlated with plasma concentrations of reverse tri-iodothyronine (rT3) but not with thyroxine (T4), free T4 (expressed as the free thyroxine(More)
Feeding experiments with growing-finishing pigs were carried out to study the effect of different dietary salinomycin concentrations upon animal performance. Besides a dietary treatment without antibiotic, three treatments consisted of 20/10 mg/kg, 40/20 mg/kg and 60/30 mg/kg salinomycin (the first and second number refer to the salinomycin content in(More)
As recommended by OECD Guidelines, percutaneous penetration studies consider intact skin, but rarely injured skin. Recent years have witnessed a growing concern for these two types of dermal exposure in the industry, particularly in the nuclear industry. The aim of this study was to show that a method based on an in vitro device can be used to realistically(More)
