Abstract:
PROBLEM TO BE SOLVED: To provide various compositions and methods which have overcome restriction in prior art and are used in achieving specific blood coagulation by providing a novel composition and a method which are for use in achieving specific coagulation e.g. coagulation of tumor vasculature and in which side effects are reduced. SOLUTION: A ligand includes following (a) and (b): (a) a first binding region which binds diseased cells, disease-related vascular components or disease-related stroma components; (b) coagulation factors or a second binding region which binds coagulation factors.

Abstract:
An impoved barrier or drug delivery system which is highly adherent to the surface to which it is applied is disclosed, along with methods for making the barrier. In the preferred embodiment, tissue is stained with a photoinitiator, then the polymer solution or gel having added thereto a defined amount of the same or a different photoinitiator is applied to the tissue. On exposure to light, the resulting system polymerizes at the surface, giving excellent adherence, and also forms a gel in the rest of the applied volume. Thus a gel barrier of arbitrary thickness can be applied to a surface while maintaining high adherence at the interface. This process is referred to herein as "priming". The polymerizable barrier materials are highly useful for sealing tissue surfaces and junctions against leaks of fluids. In another embodiment, "priming" can be used to reliably adhere preformed barriers to tissue or other surfaces, or to adhere tissue surfaces to each other. A first surface and a barrier, or another surface, are prestained with initiator, and a thin layer of gelable monomer containing initiator is placed between them. Strong adhesion is obtained between the two surfaces on gelation of the monomer. In a similar fashion, tissue surfaces can be adhered to each other in repair of wounds and formation of anastomoses. Methods for use of non-photochemical systems and combined chemical/photochemical systems are described.

Abstract:
PROBLEM TO BE SOLVED: To obtain a therapeutic composition comprising carotenoids enclosed in liposomes or other lipid carrier particles. SOLUTION: This invention discloses a reduced-toxicity formulation of carotenoids, which is stable in an aqueous environment. The formulation includes the carotenoids, lipid carrier particles (such as liposomes), and an intercalation promoter agent (such as a triglyceride) capable of substantially uniformly distributing the carotenoids together with the lipid in the lipid carrier particles. The molar ratio of carotenoids to the lipid is greater than about 1:10. Also disclosed is a method for inhibiting the growth of cancer cells, which comprises administering to a living body a therapeutically effective amount of the composition described above.
