摘要:
The invention relates to central venous polyurethane catheters with a thin hydrophilic coating loaded with an antibiotic of the ramoplanin group or any mixture thereof and their use in preventing catheter related infections. These catheters are useful to prevent bacterial adherence and colonization and, therefore, to lower the risk of vascular infections in catheterized patients. The method of preparing the catheter of the invention consists in incubating polyurethane catheters coated with a hydrophilic film in an aqueous solution of the selected antibiotic.

The present invention is directed to a new antibiotic substance denominated antibiotic A 42867 pseudoaglycon, a pharmaceutically acceptable salt thereof, a process for its preparation from antibiotic A 42867 and pharmaceutical compositions containing the new substance of the invention.
摘要:
Solid phase immunoassay for detecting specific inhibitors of proteolytic enzymes in biological fluids, which comprises: a) contacting a tubulin peptide covalently linked to a support with a solution containing a proteolytic activity together with a protease inhibitor, b) detecting the inhibitor activity against the selected proteases by contacting the support with a solution containing a labelled monoclonal antibody which specifically recognises the free end of the tubulin peptide linked to the support.
摘要:
The present invention concerns the use of puberulic or puberulonic acid as inhibitors of the enzyme iositol monophosphatase (EC 3.1.3.25) and thus useful in the treatment of manic or depressive symptoms.
