Cadmium was administered in drinking water at a concentration of 50 ppm to female Wistar rats for 5 months before mating, and then continued during gestation. The histochemical evaluation revealed a relative decrease in succinic dehydrogenase (SDH) and Mg+2-stimulated ATPase activities in duodenum, liver and kidney in the exposed rats. It is suggested that(More)
The Understanding Society survey includes what is known as an 'Innovation Panel' sample (IP). This sample of originally 1500 households is used to test different methods for conducting longitudinal surveys in order to produce the highest quality data. The results from the Innovation Panel provide evidence about the best way to conduct a longitudinal survey(More)
Non-technical summary Among many questions asked in surveys some questions ask people to reveal unpleasant sides of themselves. These questions may ask about behaviours that are not socially accepted (e.g. drug use) or not socially approved (e.g. not voting in elections). A challenge for survey design has been to improve survey reports of unpleasant(More)
Panel surveys involve interviewing the same set of people repeatedly over time. Researchers who carry out such surveys often discuss whether it is beneficial to assign to each sample member the same interviewer who interviewed them on the previous occasion. Furthermore, they would like to know how beneficial, as there are often costs associated with(More)
The investigations were performed on mice. They were divided into a control group and 4 experimental groups. The experimental animals were administered intraperitoneally benzene 6 X every 24 h. The animals were decapitated 30 min. 4, 12 and 24 h after the last benzene administration. During the experiment, dyeing for neutral lipids and glycogen was carried(More)
1. Long trem benzene action brings about a permanent decrease in oxidoreductive enzymes and active transport as well as an inactivation of the lysosomal apparatus in liver-cells. 2. Particular liver lobule zones show different sensitivity to toxic action of benzene which might result from their different role in the processes of benzene biotransformation.
