  • Patent number: 5484609
    Abstract: Compositions comprising (i) granules comprising a biologically active material in association with a weak base and partially coated with a delayed release material soluble in intestinal juice, (ii) an acidifying agent having a pH between 1.5 to 6, and (iii) a gel forming agent are described. There is also described a composition comprising an acidic gel having a pH between 1.5 to 6 and containing microgranules comprising a biologically active material in association with a weak base and partially coated with a delayed release material soluble in intestinal juice. The compositions may be used in the treatment of diseases associated with intestinal pathogens in animals. Where the biologically active material is a protease, receptor/adhesion sites in the intestines for pathogens may be proteolysed so as to prevent pathogen binding to intestinal surfaces.

  • Patent number: 5480975
    Abstract: Transition metal ions enhance the ability of the body to increase vascularization, particularly for revascularizing damaged tissues, apparently because they enhance expression of the vegF gene, so as to increase VEGF levels. According, hypoxic tissue damage can be treated or prophylactically reduced by administering a composition comprising a transition metal ion capable of stimulating vascularization. Treatment can be accomplished using compositions of matter which include a transition metal ion in a sterile, biologically compatible carrier, packaged as a unit dosage effective to increase vascularization in hypoxic tissue. For systemic administration, the transition metal ion is formulated at a concentration that is non-toxic and ineffective to increase vascularization in non-hypoxic tissue.
