    摘要: A process for the production of &bgr;-3-(1,3)(1,6) glucan from a glucan containing cellular source is described, together with compositions and uses/methods of treatment involving glucan. The process of the invention comprises the steps of: (a) extracting glucan containing cells with alkali and heat, in order to remove alkali soluble components; (b) acid extracting the cells of step (a) with an acid and heat to form a suspension; (c) extracting the suspension obtained of step (b) or recovered hydrolyzed cells with an organic solvent which is non-miscible with water and which has a density greater than that of water separating the resultant aqueous phase, solvent containing phase and interface so that substantially only the aqueous phase comprising &bgr;-(1,3)(1,6) glucan particulate material remains; wherein the extraction with said organic solvent provides separation of glucan subgroups comprising branched &bgr;-(1,3)(1,6)-glucan, and essentially unbranched &bgr;-(1,3) glucan which is associated with residual non-glucan contaminents; and (d) drying the glucan material from step (c) to give microparticulate glucan.

    摘要: A medication and method for treating wounds by contacting the wound, for a sufficient period of time, with a therapeutically effective amount of a starch hydrolysate composition including trace elements, to beneficiate the wound healing processes. A possible starch hydrolysate is maltodextrin and possible trace elements include, at least copper and zinc. The composition may also contain ascorbic acid as well as antibacterial and nutritive agents to promote formation and growth of granulation tissue.
