Provided are methods and compositions for detecting and treating normal, hypoplastic, ectopic or remnant tissue, organ or cells in a mammal. The method comprises parenterally injecting a mammalian subject, at a locus and by a route providing access to said tissue or organ, with a composition comprising antibody/fragment which specifically binds to targeted organ, tissue or cell. The antibody/fragment may be administered alone, or labeled or conjugated with an imaging, therapeutic, cytoprotective or activating agent.

Prodrugs, of generic formula (I), are disclosed for use in antibody directed enzyme prodrug therapy (ADEPT). The prodrugs are substrates for carboxypeptidase G2 (CPG2) and yield more active cytotoxic drugs than known products of CPG2 catalysed reactions, wherein R1 and R2 each independently represents chlorine, bromine, iodine, OSO2Me, or OSO2phenyl, X represents O, NH or -CH2-; Y represents O.

The present invention relates to a delivery system which includes a bioactive drug or cosmetic substance presented in the form of submicron oil spheres alone, or drugs or cosmetic substances in a combination with the oil spheres in an aqueous suspension or emulsion. Optionally, a skin penetration enhancer may be included in such formulations. Such preparations achieve improved bioavailability and exert larger pharmacological effects than an equivalent dose of the drug or cosmetic formulated in conventional creams, lotions or oleaginous bases.

Articles of manufacture which are adapted for use in contact with one or more biologically active agents are coated with a glassy carbohydrate film. The glassy film provides a reduced surface energy coating which exhibits a reduced degree of binding with biologically active agents. Methods for applying the glassy carbohydrate film are disclosed wherein the glassy film is adsorbed directly onto the article surface. The coated articles are for use both in vitro and in vivo where contact with biologically active agents is expected.
