Abstract: The field of colonic diagnostic and surgical procedures is hampered by the lack of optimal means available to cleanse the colon. A compromise between convenient, distasteful, solid or low volume, hyperosmotic solutions which cause considerable fluid and electrolyte imbalances in patients and large volume, difficult to consume, iso-osmotic solutions has had to be made heretofore. This invention describes a low volume, hyperosmotic solution consisting of sulfate salts with and with out polyethylene glycol. Unlike prior art, this composition is useful for the cleansing of the bowel and, in lower volumes, as a laxative, without producing clinically significant changes in bodily function.

Abstract: A two component system for therapeutic treatment of a host, having a first component comprising a targeting moiety capable of binding with a tumour associated antigen, linked to a mutated enzyme capable of converting a prodrug into an antineoplastic drug, and a second component comprising a prodrug convertible under the influence of the mutated enzyme to the antineoplastic drug. The mutated enzyme is a mutated form of a natural host enzyme which recognizes its natural substrate by an ion pair interaction with the substrate, wherein the mutated enzyme and prodrug have structures such that the polarity of the mutated enzyme/prodrug ion pair interaction is reversed relative to the natural host enzyme/natural substrate ion pair interaction. The first component is substantially non-immunogenic in the host and the prodrug second component is not significantly convertible into antineoplastic drug in the host by natural unmutated host enzyme.

Abstract: The present invention provides a method to achieve radioisotopic localization at tumor sites, i.e., a method of enhancing radiolabeled ligand localization to a tumor in an individual in need of such treatment, comprising the steps of: transducing the tumor with a gene encoding a membrane expressed protein unique to the tumor; and administering to said individual a radiolabeled ligand which specifically binds to the protein. The use of gene therapy technology to induce expression of high affinity membrane molecules/receptors can enhance the specificity of radioisotope localization while the use of radioactive isotopes with the ability to deliver radiation damage across several cell diameters will compensate for less than perfect transduction efficiency.

Abstract: A class of predominantly hydrophobic non-azo N-substituted 1,8-naphthalimide compounds, each bearing, at its 3-position, a nucleofuge and, at its 4-position, a heteroatomic electron-releasing group. The heteroatomic electron-releasing group is being characterized as having a heteroatom directly linked to the 4-position of the ring, and having at least one hydrogen directly attached to the heteroatom. Upon activation by an activating agent in an environment independent of the presence or absence of oxygen, these compounds generate activated species. The activated species initiate chemical changes in lipid bilayer membranes of viruses and other target cells. These changes can eradicate viruses and other target cells. The activated species can also cause structural changes in lipid and any associated proteins and polypeptides at a level beneath the surface of the membrane, leading to polymerization and crosslinking.
