Effects of chronic exposure to PCBs on the microsomal cytochrome P450 (CYP) enzymes in liver and testis of bulls (Bos taurus) were determined by comparing the constitutive and PCB-induced alkoxyresorufin O-dealkylase and testosterone hydroxylase activities. Specific inductions of the prevailing hepatic ethoxyresorufin O-deethylation and 6 beta-hydroxylation(More)
Immunological examinations were done in 30 fattening pigs from three swine farms (D., M., T.) and 20 dairy cows from one cattle farm (N.) in the district of Hodonín in 1994. At the same time, samples of stable dust deposits collected in the four farms were analysed for the contents of mercury, cadmium, lead, gamma-HCH (lindane), and total DDT and(More)
Occurrence of individual polychlorinated biphenyl (PCB) congeners in the environment, foodstuffs and other biological materials was assessed. Analysis of specific PCB congeners (28, 52, 101, 138, 153, 180), occurring in animal raw materials and foodstuffs most frequently, has been implemented. Sample processing, isolation of fat from milk, meat, organs, fat(More)
The meat and some organs of eight bulls given diet with 5% to 15% supplements of dried pig and poultry excrements for 175 days were subjected to examination for the presence of some foreign substances. The results were compared with samples from eight control bulls, fed the basal diet. Liver was not found to contain any aflatoxins B1 and M1. No(More)
The authors used in clinical practice an infusion pump driven by a rotation system with an occlusive pathway whereby the movement of the rotor is ensured by a stepper with reduction of the steps to 12,800 microsteps per revolution. As regards the degree of mechanical damage of the inserted tube of the infusion set this system did not differ from the(More)
The formation of thrombi in the haemoperfusion column is undesirable as it deprives the patient of blood elements and reduces the eliminating capacity of the haemoperfusion column. This applies in particular to patients with acute intoxications treated by haemoperfusion. In experimental haemoperfusions in animals the authors provided evidence of a close(More)
Concentrations of chlorinated pesticides (p,p'-DDE, lindane), hexachlorobenzene (HCB), sum of polychlorinated biphenyls (PCBs), and PCB congeners in breast milk during lactation and the distribution of the chlorinated compounds in fat tissue, blood serum and breast milk were pursued in five primi- or secundipara from the hinterland of a clinic of(More)
The residues of antimicrobial substances, some chlorinated and organophosphate pesticides and chemical elements were studied in the meat and organs of a group of bulls fed food-waste paste for 240 days and a group of bulls fed the same paste with an addition of poultry waste. These residues were also studied in the tissues of pigs fed the food-waste paste(More)
