    Notes: [Auszug] The experiments described here show that atractyloside, as distinct from other inhibitors of oxidative phosphorylation, is a potent inhibitor of the binding of ATP and ADP to rat-liver mitochondria. The binding of ATP and ADP was tested by addition of freshly prepared mitochondria (isolated in ...

    Notes: [Auszug] From these investigations it appeared that the only difference between the two substances concerned the effect on the magnesium-stimulated adenosine triphosphatase (ATPase). In fact, the magnesium-stimulated ATPase is inhibited by oligomycin and atractyloside using rat-liver mitochondria treated ...

    Notes: [Auszug] Using hypotonically treated rat-liver mitochondria, with reduced diphosphopyridine nucleotide or ferro-cytochrome-c as substrates, inhibition of phosphoryl-ation was observed without decrease in the rate of oxygen uptake3. The 2,4-dinitrophenol-induced adenosine triphosphatase of intact ...

    Notes: Summary The concentration of phospholipids and proteins was determined in 23 inflammatory synovial fluids obtained from human knee joints. The synovial fluid to plasma phospholipid ratio (0.48 and 0.37 at high and low inflammatory state) was lower than the value found for the total protein content (0.68 and 0.53, respectively) indicating that phospholipids were more discriminated than proteins in their transfer from plasma to the synovial space. Constant amounts of phosphatidylinositol were found in all synovial fluids, whereas trace amounts of lysophosphatidylethanolamine and phosphatidylserine were more frequent in the active inflammatory state. A decrease in the relative amounts of phosphatidylcholine and phosphatidylinositol with respect to plasma suggested the possibility of phospholipid hydrolysis in the synovial compartment. In agreement, determinations of phospholipase activity disclosed the presence of a phospholipase A2 in the fluid phase of synovial effusions. Phospholipid derivatives formed in the synovial space may thus contribute to the amplification of the inflammatory response.

    Notes: Abstract Hyaluronate of 120,000 molecular weight has been injected in the peritoneal cavity of mice to study its effect on migration of inflammatory cellsin vivo. After one day a dosedependent granulocyte migration is observed. Three days later the number of granulocytes is greatly reduced and macrophages form about half of the total cell population. Hyaluronateelicited macrophages show a decreased 5′-nucleotidase and an increased acid phosphatase activity as compared to resident macrophages. The production of superoxide anion in response to the phorbol ester tetradecanoyl-phorbolacetate, and the phagocytic activity are also enhanced. Macrophages elicited by hyaluronate secrete growth factor(s) for non-lymphoid mesenchymal cells. It is concluded that hyaluronatein vivo stimulates the migration of inflammatory cells, thus causing the recruitment of a population of stimulating macrophages. These effects may explain previous reports on the acceleration of wound healing by hyaluronate.
