    • L-amino acid oxidase is utilized to reduce the plasma level of large neutral amino acids to allow the opportunity of increased large neutral amino acid drug transport across the blood brain barrier. Preferably anti L-amino acid oxidase antibody is administered intermediate to the L-amino acid oxidase and large neutral amino acid drug administrations to deplete L-amino acid oxidase activity once the L-amino acid oxidase has caused the large neutral amino acid drug transport improving level plasma reduction of large neutral amino acids thereby to reduce or eliminate degrading of large neutral amino acid drugs by L-amino acid oxidase. The large neutral amino acid drugs include levodopa, melphalan, L-DON, azaserine, acivicin, L-alanosine and 3-(phosphonomethyl)phenylalanines. For treatment of brain tumors, the drug administration is preferably preceded by the administration of a large neutral amino acid glutathione depleting agent, e.g., L-buthionine-SR-sulfoximine. L-Amino acid oxidase is also utilized to enhance the transport of large neutral amino acid glutathione depleting agent across the blood brain barrier as an adjunct to radiation therapy of brain tumors.
    • 利用L-氨基酸氧化酶来降低大的中性氨基酸的血浆水平,以允许增加大的中性氨基酸药物在血脑屏障上的转运的机会。 优选地,抗L-氨基酸氧化酶抗体在L-氨基酸氧化酶和大的中性氨基酸药物给药中间给药,以在L-氨基酸氧化酶引起大的中性氨基酸药物转运改善后消耗L-氨基酸氧化酶活性 从而降低或消除大中性氨基酸药物由L-氨基酸氧化酶的降解。 大的中性氨基酸药物包括左旋多巴,美法仑,L-DON,重氮丝氨酸,acivicin,L-脯氨酸和3-(膦酰基甲基)苯丙氨酸。 为了治疗脑肿瘤,药物给药优选之前是施用大量中性氨基酸谷胱甘肽消耗剂,例如L-丁硫氨酸-SR-亚砜亚胺。 L-氨基酸氧化酶还用于增强大中性氨基酸谷胱甘肽消耗剂在血脑屏障上的转运,作为脑肿瘤放射治疗的辅助物质。

    • Methods of treating solid and cystic tumors are disclosed. The method comprises administering to a subject afflicted with a cystic tumor an antibody which binds to tenascin in a therapeutically effective amount. The administering step is carried out by depositing the antibody in the cyst cavity of the cystic tumor. For solid tumors, disclosed is a method involving first, removing a solid tumor from a solid tissue organ of an afflicted subject; then forming an enclosed resection cavity in the organ of the subject at the location from which the solid tumor was removed; and then administering to the subject an antineoplastic agent by depositing the antineoplastic agent in the resection cavity. Particularly preferred for carrying out the foregoing is the monoclonal antibody 81C6 and antibodies which bind to the epitope bound by monoclonal antibody 81C6.
    • 公开了治疗固体和囊性肿瘤的方法。 该方法包括向患有囊性肿瘤的受试者施用以治疗有效量结合腱生蛋白的抗体。 施用步骤通过将抗体沉积在囊性肿瘤的囊腔中来进行。 对于实体瘤,公开的方法是首先从受影响的受试者的固体组织器官去除实体瘤; 然后在移除实体瘤的位置形成被检体器官中的封闭切除腔; 然后通过将抗肿瘤剂沉积在切除腔中向受试者施用抗肿瘤剂。 特别优选进行上述操作的是单克隆抗体81C6和与由单克隆抗体81C6结合的表位结合的抗体。
