Many epidemiological studies suggest that elevated plasma fibrinogen concentrations form one of the most important independent risk factors in blood for cardiovascular disease and particularly atherosclerosis in humans. To clarify the effect of genetic factors, diets and their interactions on plasma fibrinogen concentrations, we examined plasma...

The metabolism of the illegal growth promoter ethylestrenol (EES) was evaluated in bovine liver cells and subcellular fractions of bovine liver preparations. Incubations with bovine microsomal preparations revealed that EES is extensively biotransformed into norethandrolone (NE), another illegal growth promoter. Furthermore, incubations of...

Several mechanisms have been postulated to explain the relatively high immunogenicity of antigens presented in immune-stimulating complexes (iscom). Their potency can in part be explained by the specific targeting of these structures to cells presenting antigens to the immune system. However, until now no method for the subcellular detection of...

Earlier studies have shown that retinoid administration suppresses the generation of hepatic fibrosis and stimulates its regression in normal (i.e., vitamin A-sufficient) carbon tetrachloride-treated rats. This study focuses on the possible role of a marginal or deficient vitamin A status on carbon tetrachloride-induced fibrosis. This...

A fast and simple method for the in vivo/in situ detection of liposomes is described. Utilizing lipophilic carbocyanine dyes, DiI and DiO, yellow (or red) and green fluorescent liposomes can be visualised with routinely available filters. The main advantages of the method are (i) the vesicles can be labelled after they are formed and (ii) the...

An experiment was conducted to examine the effects of graded levels (2.5, 5.0, 7.5, 10.0, and 15.0%) of dietary D-xylose or L-arabinose on chick performance. As reference, D-glucose was included in the experiment. A second experiment was performed to determine the AMEn of D-xylose and L-arabinose. Results of Experiment 1 showed a significant...

Intracellular accumulation of 37°C of 50 μM [14C]taurocholic acid by hepatocytes of pig and rat, cultured for 24 hours, and by human hepatocytes, cultured for 12 hours, reached equilibrium after an incubation time of 1 to 2 hours. Maximum capacity to accumulate taurocholate intracellularly was assessed in 3-hour incubations with increasing...

To investigate the regulation of age-related changes in albumin synthesis in the rat liver, total postnuclear RNA and polyribosomes, both membrane-bound and free, were prepared from livers of rats of different ages. By the use of a specific complementary DNA probe, the albumin mRNA sequence content was quantitated in these RNA fractions. These...

A lifespan oral toxicity of vinyl chloride monomer (VCM) was carried out in Wistar rats, using five groups each of 60-80 males and 60-80 females. VCM was administered by incorporating polyvinyl chloride (PVC) powder with a high VCM content into the diet or by gastric intubation of a 10% VCM solution in soya-bean oil. The VCM doses (actual...

Adriamycin (ADR) accumulates in well-perfused organs in the rat. This effect is especially evident for long periods in marrow and spleen of healthy animals. In rats bearing the Brown Norway Acute Myeloid Leukaemia (BNML) the in vitro distribution is significantly different. Maximum ADR levels in those organs which are morphologically infiltrated...

Hepatocyte morphology of the three zones of the liver lobule was evaluated by stereological analysis in 3-month-old and 35-month-old virgin female WAG/Rij rats. In the old rats, the volume of the nucleus and cytoplasm, and volume densities of smooth endoplasmic reticulum and lysosomes were increased in all areas of the liver lobule, while the...

Highly purified suspensions of parenchymal, endothelial and Kupffer cells were prepared from the rat liver. The respective roles of these cell classes in the degradation of proteins was investigated by analysing the cellular distribution of two lysomal proteases. The specific arginine naphthylamidase activity was 2 times higher in Kupffer cells...

A new oral cholecystographic medium called iocetamicacid was submitted to a toxicologic study in rats and dogs. Dosages, which were equivalent to 200 and 1000 mg of the compound per kilogram of body weight per day and were 5 times and 25 times the human routine dose, were administered daily for 3 weeks in order to establish whether the substance...
