    • The present invention relates generally to the preparation and use of biological tissue adhesives which rely on combining fibrinogen and thrombin. More particularly, the present invention relates to a method of preparing a fibrin sealant whereby said sealant is formed by reconstituting the fibrinogen or the thrombin component in the presence of biological and/or non-biological agents such as drugs, chemicals, and proteins. Preferably, these agents are introduced in solution, such as for example, a corticosteroid-containing solution like a betamethasone solution containing betamethasone acetate or betamethasone sodium phosphate; a triamcinolone solution; or a methylprednisolone solution. These solutions may be substituted for, or provided as a complement to, other solutions that are typically used in the preparation of fibrin sealants such as, for example, calcium chloride. The invention further relates to a novel method of using the improved fibrin sealant whereby the sealant and accompanying agent(s) are delivered directly to a critical site within the body and sealed in place due to the bio-static quality of the sealant. This provides therapeutic value to patients through prolonged presence, and optionally time-released delivery, of the specific agent(s) at the critical site.
    • 本发明一般涉及依赖于组合纤维蛋白原和凝血酶的生物组织粘合剂的制备和应用。 更具体地说,本发明涉及一种制备纤维蛋白密封剂的方法,其中所述密封剂通过在生物和/或非生物制剂如药物,化学品和蛋白质的存在下重构纤维蛋白原或凝血酶组分来形成。 优选将这些试剂引入溶液中,例如含有皮质类固醇的溶液,如含有醋酸倍他米松或倍他米松磷酸钠的倍他米松溶液; 曲安奈德溶液; 或甲基强的松龙溶液。 这些溶液可以代替通常用于制备纤维蛋白密封剂例如氯化钙的其它溶液的补充,或作为其补充。 本发明还涉及使用改进的纤维蛋白密封剂的新方法,其中密封剂和伴随剂直接输送到体内的关键部位并由于密封剂的生物静态质量而被密封就位。 这通过在关键部位的特定药剂的长期存在和任选的时间释放的递送来为患者提供治疗价值。

    • A composition of matter is prepared by a process comprising the steps of impregnating a alumina-containing support material with a thiosulfate (preferably ammonium thiosulfate), drying the thus impregnated material, impregnating the dried material with a transition metal compound, drying and calcining the transition metal impregnated material. This composition of matter is used as catalyst composition for hydrogenating unsaturated hydrocarbon compounds, and as catalyst composition for hydrotreating hydrocarbon-containing feed streams (in particular heavy oils) which contain metal and sulfur compounds as impurities.In another embodiment, a hydrotreating process comprises contacting hydrocarbon-containing feed stream (in particular heavy oils), which contains compounds of sulfur and metals, in the presence of a fixed catalyst bed comprising (X) at least one layer of impregnated substantially spherical alumina-containing particles, which have been prepared by a process comprising the steps of impregnating a specific starting material with (NH.sub.4).sub.2 S.sub.2 O.sub.3 and then heating the thus impregnated material at about 500.degree.-900.degree. C. for improved crush strength retention. In a preferred embodiment, the fixed catalyst bed further comprises at least one layer (Y) of catalyst particles comprising a refractory inorganic carrier and at least one hydrogenation promoter. A composition of matter comprising the impregnated, spherical alumina-containing particles described above, and a process for preparing them are also provided.
