Abstract: An adjuvant for use in a vaccine, the adjuvant comprising one or more cationic substances such as, e.g., acyl amines comprising from 4 to 30 carbon atoms, 5 quaternary ammonium compounds derived from acyl amines, cationic acyl amides, amino acids conjugated to an acyl group, etc., and mixtures thereof.

Abstract: A tuberculosis (TB) vaccine composition is disclosed. The composition comprises, as adjuvant, one or more substances selected from a) monoglyceride preparations having at least 80% monoglyceride content and b) fatty acids of the general formula CH3—(CH2)n—COOH where “n” may be varied between 4 and 22, and where the acyl chain may contain one or more unsaturated bonds, and as immunizing component, inactivated, e.g. heat killed or formalin killed, Mycobacterium tuberculosis bacteria.

Abstract: A vaccine formulation against a microorganism is disclosed. The formulation comprises: as adjuvant, one or more substances selected from a) monoglyceride preparations having at least 80% monoglyceride content and b) fatty acids of the general formula CH3—(CH2)n—COOH where “n” may be varied between 4 and 22, and where the acyl chain may contain one or more unsaturated bonds, and as immunizing component, an immunogenic product consisting of antigenically active carbohydrate moieties (ACM) derived from said microorganism which are each covalently coupled, possibly via identical divalent bridge groups, to immunologically active carriers (IAC). The vaccine formulation is e.g. against Mycobacterium tuberculosis and in that case the formulation may comprise, as adjuvant, a mixture of mono-olein and oleic acid, and possibly soybean oil, and, as immunizing component, lipoarabinomamman-tetanus toxoid (LAM-TT).

Abstract: The invention shows that it is possible to produce a depot matrix for biologically active substances, consisting of carbohydrate microspheres, such that the carbohydrate polymers included in the microsphere are stabilized to a microsphere by crystallization, which implies using non-covalent bonds, the substance enclosed retaining its biological activity.

Abstract: Magnetically responsive spheres having an average diameter less than 1,000 nm are prepared by dissolving a carbohydrate polymer in a polar solvent, suspending magnetic material in the dissolved carbohydrate, emulsifying the suspension with an emulsion liquid to form an emulsion containing droplets of the suspension and then contacting the emulsion with a crystallizing liquid capable of crystallizing the carbohydrate polymer. The resulting spheres may be bonded with a bioabsorptive material and can be employed in processes such as cell separation, affinity purification or immunochemical assays.

Abstract: An intravascularly administrable, magnetically responsive nanosphere or nanoparticle made up of a crystalline carbohydrate matrix, preferably starch, enclosing a magnetic material, is described. The nanosphere or nanoparticle is produced by dissolving a carbohydrate together with a magnetic material to form a solution which is emulsified in a hydrophobic solvent from which the carbohydrate is crystallized.The resulting magnetic nanospheres having an average diameter not exceeding 1500 nm are capable of transporting pharmacologically active substances and can be injected intravenously for subsequent concentration in a part of the body by means of a magnetic field.
