BACKGROUND Mastitis is the most important and costly disease in dairy goat production. Subclinical mastitis is common in goats and is mainly caused by contagious bacteria. Several methods to diagnose subclinical mastitis are available. In this study indirect measurement of somatic cell count (SCC) by California Mastitis Test (CMT) and direct measurement of(More)
Three microdialysis methods, the "tritium" method, the "point-of-no-net-flux" method, and a method using the low perfusion rate of 0.1 microliter/min, were compared with respect to their ability to generate estimates of unbound steady-state concentrations (Cu(ss)) of the antiasthmatic drug theophylline in blood and brain tissue in anesthetized rats.(More)
The efficiency of thin-layer capping in reducing sediment-to-water fluxes and bioaccumulation of polychlorinated dibenzo-p-dioxins and dibenzofurans, hexachlorobenzene, and octachlorostyrene was investigated in a boxcosm experiment. The influence of cap thickness (0.5-5 cm) and different cap materials was tested using a three-factor experimental design. The(More)
When planning a Leksell GammaKnife/spl reg/ treatment, dose planners place iso-centres of the irradiation field in such a way that a certain iso-dose surface conforms as closely as possible to a target, such as a tumour. Today this planning is done primarily in 2D, and the clinician places the iso-centres onto the current medical image. The images used are(More)
The tumor-promoting activity of the anthraquinone laxative danthron was studied by giving 3 groups of male rats a single subcutaneous injection of the colon tumor-inducing agent 1,2-dimethylhydrazine (DMH). After 1 week, the animals were fed diets containing 0, 600 or 2400 ppm of danthron for 26 weeks. Two other groups of rats were included in the study;(More)
Sweden is a low endemicity country for hepatitis B virus (HBV). The previously reported prevalence of chronic HBV is <1% and of overall markers <5%. HBV is not included in the universal childhood vaccination programme. Instead, selected high-risk groups are targeted. Our aim was to examine the HBV seroprevalence in youth clinic clients in Stockholm and(More)
A systemic exposure-based alternative to the MTD (maximally tolerated dose) for high-dose selection in carcinogenicity studies of pharmaceuticals has been accepted by the ICH (International Conference on Harmonisation of Technical Requirements for the Registration of Pharmaceuticals for Human Use). As a result of a retrospective analysis performed by the(More)
This paper is a review of published and unpublished results on heparin during the last two years. Results and experiences gathered in our laboratory at MPA in Sweden, from the collaborative NMR study on heparin in Europe (coordinated by EDQM), and from the process of drafting heparin Ph. Eur. monograph texts where new ideas and experiments have been(More)
