    摘要: A tumor-associated marker protein was purified and antibodies thereto developed for cancer diagnosis and assessment of cancer risk associated with the long-term use of synthetic steroid hormones, both contraceptive and non-contraceptive, and other drugs that exhibit tumor promotional properties. The marker protein and antibodies thereto provided are interspecies immunologically cross-reactive.In summary, the marker p65 tumor-associated factor of the present invention has the following characteristics:(a) binds substantially completely to a phenyl hydrophobic interaction column in a buffer containing 20% ammonium sulfate and eluted at ca. 16% ammonium sulfate;(b) localized primarily in the nuclear envelopes with only small amounts present in the cytoplasm from where is released to the blood circulation in vivo or cell culture medium in vitro;(c) induced in normal, adult tissues by chemical carcinogens (initiators) but not by tumor promoters, the carcinogen-induced production being enhanced by the latter.Also disclosed herein are processes for purifying the 65 kDa tumor marker from plasma, tumor cytosol or ascitic fluid of carcinoma bearing animals; processes for producing antisera and purified antibody preparations to the 65 kDa tumor marker; and methods using antibody to the 65 kDa to diagnose or assess the likelihood of cancer.

    摘要: A method for the reduction in vivo of the inappropriate levels of endogenous and environmental-derived compounds by inhibiting the activity of .beta.-glucuronidase in a mammal which comprises the administration to the mammal of an effective amount of a water insoluble, or sparingly soluble, sustained release precursor of glucarolactone or its analog is disclosed. The sustained release precursor of glucarolactone compound is selected from the group consisting of D-glucaric acid, D-galactaric acid, and L-idaric acid or derivatives or analogs. An orally administrable preparation of the sustained release precursor of glucarolactone compound is provided in the form of a capsule tablet, such that the glucarolactone or its analog is slowly released in the stomach of the treated animal or human.
