The purposes of this review are to assess the human exposure and human and experimental evidence for adverse effects of brominated flame-retardants (BFRs) with specific focus on intake from seafood. The leakage of BFRs from consumer products leads to exposure of humans from fetal life to adulthood. Fish and fish products contain the highest levels of BFRs(More)
The activity of carboxylesterase and cholinesterase in plasma, liver and lung of young rats at different ages (5-31 days old) have been measured. The cholinesterase activity in the tissues of both sexes were almost constant during the development, and were similar to adult male activity. The carboxylesterase activity towards methyl butyrate and(More)
The organophosphorus compound trichlorfon, dimethyl (2,2,2-trichloro-1-hydroxyethyl) phosphonate, was administered by stomach tube (100 mg/kg) to pregnant guinea pigs at two different stages of gestation (days 36, 37, 38 and 51, 52, 53). The pups developed locomotory disturbances, and post mortem examination revealed significantly decreased weights of the(More)
Radiolabelled trichlorfon, dimethyl-(2,2,2-trichloro-1-hydroxyethyl)phosphonate, was administered by stomach tube to pregnant guinea pigs on days 37 and 52 of gestation and examined by the whole body autoradiography method. The results showed that the radiolabelled compound was rapidly distributed to the main organs of the dam with the highest(More)
This study investigated the influence of zinc bacitracin on the intestinal flora of horses. The functionally active intestinal flora was examined in 6 horses during treatment with zinc bacitracin. Utilising gas chromatography, spectrophotometry, gel electrophoresis and paper chromatography, samples were analysed on biochemical markers reflecting the action(More)
The efficacy of ivermectin against natural infection of the mange mite Sarcoptes scabiei var canis in foxes was evaluated. The investigations consisted of two field studies and one controlled study. In experiment 1, ivermectin was given as a single subcutaneous dose at 200 micrograms/kg in six foxes. In experiment 2, was one group, consisting of five(More)
