The mechanism of elimination of blood-borne Vibrio salmonicida lipopolysaccharide (LPS) from Atlantic cod (Gadus morhua L.) was studied. The anatomical distribution of LPS was determined using both morphological and radiotracing methods. Immunohistochemistry performed on tissue specimens after injection of LPS disclosed that the endocardial endothelial(More)
Studies over the last two decades have shown that mammalian nonmacrophagic liver endothelial cells clear the blood from numerous physiological and foreign waste macromolecules, such as polysaccharides and proteins released during extracellular matrix turnover, intracellular macromolecules, modified serum proteins, and bacterial and fungal proteins(More)
The catabolic fate of circulating hyaluronan and the proteoglycan chondroitin sulphate (CSPG) was studied in the Atlantic cod (Gadus morhua L.). Distribution studies using radio-iodinated ligand demonstrated that CSPG was rapidly eliminated from the blood by the endocardial endothelial cells (EECs) of the heart atrium and ventricle. The presence of excess(More)
DNA vaccines are administered in the form of plasmid DNA (pDNA) carrying a strong promoter and the gene of interest. In this study we investigated the tissue distribution, cellular uptake and the fate of intravenously (i.v.) and intramuscularly (i.m.) injected pDNA in Atlantic cod (Gadus morhua L.). The anatomical distribution of pDNA was determined using(More)
In this study we investigated tissue distribution of pDNA after intramuscular and intravenous administration, cellular localisation, receptor-specific uptake, integrity of pDNA and transgene expression in Atlantic salmon (Salmo salar L). Anatomical distribution of plasmid DNA was determined using both radiotracing and fluorescence microscopy. Cellular(More)
There is evidence of effects of morphine on cell proliferation and intraarticular morphine produces analgesia and has an anti-inflammatory effect in chronic arthritis. The effects of opioids are mediated through the G-protein-coupled receptors affecting the cAMP pathway. We demonstrated that human osteoarthritic cartilage and cultured chondrocytes possess(More)
The long-term persistence and activity of a naked plasmid DNA (pGL3-35S) containing a luc gene (reporter gene) controlled by a plant 35S CaMV promoter was studied in Atlantic salmon (Salmo salar L.) after injection. Atlantic salmon (mean weight 70 grams) were injected intramuscularly with 100 μg of plasmid DNA. Blood, different tissues and organs were(More)
Atlantic lumpfish (Cyclopterus lumpus L.) is used as a biological delousing agent for sea lice (Lepeophtheirus salmonis K.) infestations in Norwegian aquaculture. Here, we present a study on the antibody response and vaccine side effects after intramuscular and intraperitoneal injection of lumpfish with two vaccines. Both vaccines contained bacterial(More)
of the cell envelope of gram-negative bacteria. The lipopolysaccharide (LPS) molecule is composed of three structural units; the O-polysaccharide, a core oligosaccharide and a lipophilic lipid A component. The lipid A portion represents the endotoxic component of LPS and is responsible for the typical endotoxin effects observed in mammals, such as fever,(More)
The first aim of the present study was to evaluate the bioavailability of ibuprofen dispersed in a novel soft chewable formulation compared with a traditional ibuprofen tablet; its second was to map the quality of taste masking and patient product satisfaction. In a phase 1, single-center, open-label, randomized, crossover study, healthy subjects received a(More)
