    摘要: A process for preparing dermatan sulphate (DS) of pharmaceutical purity from animal organs rich in mucopolysaccharides (MPS), by: (a) stabilizing the fresh organs by freezing them either as such or in the form of powder, (b) micronizing the material containing the MPS with an aqueous CaCl.sub.2 solution, (c) digesting the homogenate comprising the raw material and the CaCl.sub.2 with proteolytic enzymes at alkaline pH and at low temperature, (d) acidifying, heating and filtering the lysate, (e) treating the filtrate with quaternary ammonium salts able to undergo complexing with and thus precipitate either the DS along or all the MPS selectively, (f) recovering and purifying the DA either directly from the ammonium salt complex containing it or from the complex obtained from the mixture of ammonium salt complexes of all the MPS by fractional solubilization with acetone.

    摘要: A process for the controlled preparation of low molecular weight glucosaminoglycans by treating conventional high molecular weight glucosaminoglycans in the solid state or in solution form with a rectilinear gamma ray beam at doses within the range of 2.5 to 20 Mrad supplied by successive irradiation stages with cooling intervals between one irradiation stage and the next in the dynamic phase.The mixture obtained is subjected to fractionation, purification, neutralization and lyophilization. The glucosaminoglycans obtained have a molecular weight of between 1000 and 35,000 daltons and are used for the preparation of pharmaceutical compositions possessing antithrombotic, fibinolytic, antiatherogenic and heparin cofactor II activation activity.

    摘要: The present invention relates to cosmetological and dermatological compositions comprising heparan sulfate. The invention further discloses a process for the purification of heparan sulfate for dermatological and cosmetological applications, which process comprises the following steps: solubilization of heparan sulfate in water, adsorption on an anion exchange resin, desorption from the resin by using conditions which result in selective desorption of hepar an sulfate. The cosmetological and dermatological compositions according to the invention show, inter alia, anti-age, lenitive, and whitening effect.

    摘要: A process for producing natural heparan sulphate and dermatan sulphate for mixtures of proteoglycans from the aorta, myocardium and particularly vascularized organs, based on a series of precipitation and purification steps which enable the protein part of the proteoglycan to be eliminated and the two products to be obtained in substantially pure form, without any chemical or enzymatic degradation.When administered orally or parenterally, the heparan sulphate obtained exerts activation effects on antithrombin III and on the fibrinolytic process.The dermatan sulphate obtained exerts an inhibiting effect on Factor Xa and also possesses the property of activating the fibrinolytic effect of heparan sulphate.
