Abstract: The healing of a surface wound is promoted by contacting the wound surfaces with a suspension of particles of collagen and a glycosaminoglycan that is chemotactic of fibroblasts and/or endothelial cells. Typical glycosaminoglycans that exhibit the desired chemotaxis are heparin, heparan sulfate, and alginate. Two or more glycosaminoglycans can be present in the suspensions. Collagen and glycosaminoglycan are present as a dry powdered suspension of particles. Preferably, collagen is present in the suspension in the order of 7-10 mg/ml; while the glycosaminoglycan is present in much lower concentrations, e.g., 250-350 .mu.g/ml. Application of the collagen/glycosaminoglycan suspension to open wounds greatly increases the rate of healing.The invention includes, an article, useful in the therapy for surface wounds, comprising the suspension of particles on a gauze, bandage tape or the like.

Abstract: A diuretically active combination comprising furosemide and triamterene in a ratio of 1:1 to 1:2, in which furosemide is in the form of controlled release so as to facilitate solubilization of the furosemide in triamterene micelles to stabilize the combination as mixed micelles of low polydispersity yielding dissolution rates in in vitro tests of furosemide of not more than about 1.5% after about one hour at pH 1.5 to 3.5 and a slow release of not more than about 4.5% at pH 5.5 concurrent with a release of triamterene of about 60-70% and 80%, respectively, and with a release of not more than 85% furosemide after eight hours at pH 7.5 in salt solutions of adjusted pH.
