    • Otitis externa is treated in dogs and cats by administering to the outer ear of the infected animal a dosage, effective to alleviate the symptoms of the infection, of a substantially non-aqueous, di-enzymatic therapeutic composition, in a liquid or gel fluid carrier. The composition contains an oxidizable substrate and an oxidoreductase enzyme specific to such substrate for producing hydrogen peroxide upon encountering the environment of the outer ear and further contains an iodide salt and and a peroxidatic peroxidase for interacting with the hydrogen peroxide to produce a hypoiodite biocidal agent. Any unbound water present in the composition is limited to an amount not more than about 1.0 wt. % to stabilize the composition against the production of hydrogen peroxide prior to aural application of the composition to enhance efficacy of treatment. An illustrative di-enzymatic composition composition contains glucose, glucose oxidase, potassium iodide and lactoperoxidase in a fluid mixture of glycerol and propylene glycol.
    • 通过向受感染动物的外耳施用在液体或凝胶流体载体中施用有效缓解感染症状的基本上非水性的二酶治疗组合物的剂量,在狗和猫中治疗外耳炎。 。 组合物含有可氧化底物和对这种底物特异性的氧化还原酶,用于在遇到外耳的环境时产生过氧化氢,并且还含有碘化物盐和过氧化物过氧化物酶,用于与过氧化氢相互作用以产生次碘酸盐杀生物剂。 存在于组合物中的任何未结合的水都限制在不超过约1.0wt。 %以在组合物的耳道施用之前稳定组合物抵抗过氧化氢的产生,以增强治疗的功效。 示例性的二酶组合物组合物在甘油和丙二醇的流体混合物中含有葡萄糖,葡萄糖氧化酶,碘化钾和乳过氧化物酶。

    • An orally chewable, enzymatically coated product is provided which, upon chewing, produces an anti-bacterial and bacteriostatic effect in the oral cavity by activation of an enzymatic system contained within the coating. The enzymatic surface coating is developed, in substantially dry form, from a thickened, aqueous coating solution having a viscosity from about 1,000 to about 50,000 centipoises and containing oxidizable substrate and oxidoreductase enzymes specific to such substrate for producing hydrogen peroxide upon oral chewing of the coated product and optionally, but advantageously, further containing peroxidatic peroxidase and an alkali metal salt of an oxygen accepting anion for interacting with hydrogen peroxide to produce oxidized anionic bacterial inhibitor. An illustrative enzymatic system for this purpose contains glucose, glucose oxidase, potassium thiocyanate and lactoperoxidase. The thickened enzymatic solution suppresses the enzymatic reaction during the preparation and application of the solution to the surface of the chewable product.
    • 提供口服咀嚼的酶促涂覆的产品,其在咀嚼时通过激活包含在涂层内的酶系统在口腔中产生抗细菌和抑菌作用。 酶表面涂层以基本上干燥的形式从具有约1,000至约50,000厘泊的粘度的增稠的水性涂料溶液展开,并且包含可氧化底物和氧化还原酶特异性的这种底物,用于在涂覆的口腔咀嚼时产生过氧化氢 产物和任选地但有利地还含有过氧化物过氧化物酶和氧接受阴离子的碱金属盐,用于与过氧化氢相互作用以产生氧化的阴离子细菌抑制剂。 用于此目的的说明性酶系统包含葡萄糖,葡萄糖氧化酶,硫氰酸钾和乳过氧化物酶。 增稠的酶溶液在将溶液制备和施加到咀嚼产品的表面期间抑制酶反应。
