摘要:
The invention relates to pharmaceutical compositions intended to decrease the incidence of tumor metastasis in patients who suffer from malignant diseases.The pharmaceutical compositions of the invention contain as active ingredient heparin or a suitable derivative thereof. Amongst suitable derivatives are N-desulfated and N-acetylated heparin.The dosage of the administered heparin or heparin derivative is quite critical and will generally be in the range of from 0.05 mg/kg/day to about 0.5 mg/kg/day. A preferred range is between about 0.1 mg/kg/day to about 0.5 mg/kg/day.

摘要:
Heparanase activity in a patient may be inhibited by administering an effective heparanase-inhibiting amount of heparin or an effective chemically modified derivative of heparin which inhibits heparanase activity. Such derivatives are preferably N-desulfated, N-acetylated heparin or O-desulfated, N-acetylated heparin. By means of this invention, allograft rejection may be prevented or delayed and autoimmune diseases such as arthritis may be alleviated and treated.
摘要:
Methods and kits for distinguishing between heparanase expressing and heparanase non-expressing hematopoietic cells, particularly useful in distinguishing between different types of differentiated and/or undifferentiated lymphomas and leukemias. The methods and kits are designed to detect heparanase expression, or absence thereof, at the gene, protein and/or protein activity levels.

摘要:
The present invention relates to a novel VEGF protein product, and nucleic acid encoding the novel protein product, comprising exons 1-6 and 8 of the VEGF gene, and its use thereof in treating the cardiovascular system and its diseases through effects on anatomy, conduit function, and permeability. VEGF145 has been found to be an active mitogen for vascular endothelial cells and to function as an angiogenic factor in-vivo. VEGF145 has novel properties compared with previously characterized VEGF species with respect to cellular distribution, susceptibility to oxidative damage, and extra-cellular matrix (ECM) binding ability. The present invention provides methods of treating the cardiovascular system, enhancing endothelialization of diseased vessels, and enhancing drug permeation by providing the novel VEGF protein product. The invention also provides expression vectors, compositions, and kits for use in the methods of the invention.
摘要:

摘要:
The present invention is directed to sulfated oligosaccharides having 4, 5 or 6 saccharidic units and wherein a glycosidic bond between two saccharide units is substituted by a C—C bond, and wherein the sulfation degree expressed as percentage of OH groups substituted by a OSO3− group is comprised between 50 and 100%. The sulfated oligosaccharides according to the invention are useful as a drug, in particular in the treatment of angiogenesis, metastasis, and inflammation.
