Tetrachlorohydroquinone (TCHQ), which has previously been identified as a metabolite of pentachlorophenol, induces DNA strand breaks in isolated DNA and in human fibroblasts. Strand break formation in PM2 DNA is prevented by the addition of catalase and the hydroxyl radical scavengers DMSO, ethanol and mannitol, whereas addition of SOD reduced SSB only(More)
General anaesthesia with 80% CO2/20% O2 and 5% halothane in O2 (mask induction) was compared for castration of 3-4 week-old piglets. One group was castrated without anaesthesia. Of the noncastrated control groups one had CO2- and one halothane anaesthesia, one breathed room air through the induction system, and one was held in castration position. The(More)
Blood vitamin A profiles, including concentrations of retinol and its active metabolite retinoic acid, were assessed during the peripartum period and during experimentally induced Escherichia coli mastitis in heifers. Serum retinol decreased in all animals in the immediate postpartum period and normalized within 1 wk after parturition. No significant(More)
This review is focused on the possible interactions of prolactin and somatotrope hormone in the modulation of inflammation of the mammary gland. Several different models are examined: Escherichia coli, Streptococcus uberis, and endotoxin mastitis. Subsequently, the release of growth hormone and insulin-like growth factor during fever and mastitis, the(More)
Oncomodulin (OM) is a Ca2+ binding protein (CABP) structurally closely related to parvalbumin. Expression of OM is restricted to early embryonic stages, the placental cytotrophoblasts, and neoplastic tissues. The function of OM as a calmodulin (CaM)-like enzyme modulator is controversial. Two types of experiments demonstrate that OM may act in an analogous(More)
We monitored expression of PD-1 (a mediator of T-cell exhaustion and viral persistence) on hepatitis C virus (HCV)-specific CD8(+) and CD4(+) T cells from blood and liver during acute and chronic infections and after the resolved infection stage. PD-1 expression on HCV-specific T cells was high early in acute infection irrespective of clinical outcome, and(More)
The industrial pollutant 2,4,5-trichlorophenol (2,4,5-TCP) was metabolized with postmitochondrial liver fraction from Aroclor-1254 induced rats. The generated metabolites induced single strand breaks in PM2 DNA. Among the metabolites produced are the 3,4,6-trichlorocatechol (TCC) and the 2,5-dichlorohydro-quinone (DCH), whereby the induction of DNA scission(More)
Disturbed Ca2+ handling and altered levels of Ca(2+)-binding proteins (CaBPs) have been found in many transformed cells. To investigate whether there exists a correlation between expression of CaBPs and intracellular Ca2+ we analyzed three transformed rat fibroblast cell lines (T14, T10, and T43) exhibiting different levels of CaBPs. All three cell lines(More)
Adding ammonium ferric hexacyanoferrate (AFCF) to cows' fodder produced after the Chernobyl nuclear accident prevented milk contamination by increasing the faecal elimination of 137Cs. Synthesis of ammonium ferric hexa[14C]-cyanoferrate (AF14CF) and its purification were performed for the study of the metabolic fate of this complex, and the evaluation of(More)
