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 experiment was carried out on rats, which were divided into three experimental and one control groups. The experimental animals were intraperitoneally injected with furfural in the dose of 58 mg/kg body weight for 30 days. In the liver samples obtained at autopsy, apart from routine staining with hematoxylin and eosin, estimation of the activity of the(More)
We assess whether the probability of a sample member participating at a particular wave of a panel survey is greater if the same interviewer is deployed as at the previous wave. Previous research on this topic mainly uses non-experimental data. Consequently, a) interviewer change is generally non-random, and b) continuing interviewers are more experienced(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.
We assess whether the probability of a sample member co-operating at a particular wave of a panel survey is greater if the same interviewer is deployed as at the previous wave. Previous research on this topic mainly uses non-experimental data. Consequently, a) interviewer change is generally non-random, and b) continuing interviewers are more experienced by(More)
