    • A process and system for controlled delivery of a biologically active substance to an animal body fluid which comprises contacting fluid with a reversible complex of a conjugate (1) and a binding macromolecule (2), wherein the conjugate (1) comprises a biologically active portion which is intended to be proportionately released into a body fluid stream in response to varying concentration levels of a component of the body fluid stream, and a complexing substrate portion which conjugates with the biologically active portion and which is characterized by affinity to the binding macromolecule (2), competitivey or non-competitively with the variable component of the body fluid; thereby causing the component present in the body fluid to complex to the binding macromolecule and thus releasing the conjugate (1) therefrom into the fluid.The process and system are particularly applicable for the glucose-controlled release of insulin and other hypoglycemic agents in the treatment of diabetes.
    • 一种用于将生物活性物质受控输送到动物体液的方法和系统,其包括使流体与缀合物(1)和结合大分子(2)的可逆复合物接触,其中所述缀合物(1)包含生物活性部分 其旨在响应于体液流的组分的不同浓度水平而成比例地释放到体液中,以及与生物活性部分共轭并且其特征在于对结合大分子的亲和力的络合底物部分( 2),与体液的可变成分有竞争力或非竞争性; 从而使存在于体液中的组分与结合大分子复合,从而将共轭物(1)从其中释放到流体中。 该方法和系统特别适用于糖尿病治疗中胰岛素和其他降血糖药的葡萄糖控制释放。

    • A method and associated agents for the arrest of infections resulting from organism growth in contact with an iron-containing body fluid, comprising administering an agent capable of immobilizing the body fluid so that the iron it contains is nutritionally unavailable for the organism. In the instance where the body fluid is blood, the agent may be administered in amounts effective to bind all of the available red blood cells or hemoglobin, to prevent breakdown of either and consequent release of iron to the organism.The agents preferably include materials capable of binding red blood cells and iron, such as haptoglobin, colloidal silica, anion exchange resins and mixtures thereof. Preferably, colloidal silica is used either alone or in a composite with a polyolefin elastomer such as polyisobutylene.The agents may be coated on carriers or substrates, such as gauze pads, tampons and the like, and may be thus utilized topically, as well as intraperitoneally.
    • 一种用于阻止与含铁体液接触的生物体生长引起的感染的方法和相关药物,其包括施用能够固定体液的药剂,使得其含有的铁在生物体内不可用。 在体液为血液的情况下,可以有效地结合所有可用的红细胞或血红蛋白的剂量施用该药剂,以防止铁分解并随之释放到生物体中。 试剂优选包括能够结合红细胞和铁的材料,例如触珠蛋白,胶体二氧化硅,阴离子交换树脂及其混合物。 优选地,胶体二氧化硅单独使用或与聚烯烃弹性体如聚异丁烯的复合材料中使用。 药剂可以涂覆在载体或基底上,例如纱布垫,卫生棉条等,并且可以局部地以及腹膜内地使用。
