Abstract: The present invention encompasses compositions wherein a GLP-1 compound is complexed with a basic polypeptide. The compositions provide a prolonged duration of action and can be administered by the pulmonary route.

Abstract: A method for enhancing the therapeutic effectiveness of adriamycin, in the treatment of cancer, is disclosed. Liposomes containing coentrapped adriamycin and a secondary compound effective to reduce the toxicity of adriamycin or enhance the induction by adriamycin of the tumoricidal activity of host lymphoid cells, such as lipopolysaccharide, are administered parenterally in a therapeutically effective dose. In another aspect, macrophages stimulated in vivo with liposomes containing entrapped liposomes are exposed to an immunostimulator, for enhanced tumoricidal activity. Also disclosed are liposome compositions containing coentrapped adriamycin and an immunostimulator.

Abstract: This invention provides an optical fan system for projecting a planar fan of light against a surface. A source of collimated light is passed into an edge face bridging between two cylindrical concentric reflective surfaces defining outer surfaces of a translucent or transparent body. The light refracts through the edge face, and then is multiply reflected and refracted between the concentric cylindrical surfaces, with total reflection occurring at the internal surface and partial refraction occurring at the outer surface. Suitable silvering or other reflective material is applied to the surfaces in order to accomplish the desired degree of reflectivity.
