Abstract: Sucrose ester and ether products, useful as food or beverage bulking agents, reduced calorie sweeteners, fat replacement agents, stabilizing agents, thickening agents and emulsifying agents; adhesives; biodegradable plastics and films; sizing agents for paper and textiles; ethical pharmaceuticals and new fibers are prepared by using a two-phase reaction system in which sucrose is dissolved in an alkaline, aqueous solution and an acidic reagent such as a bifunctional acid dichloride or epoxide is added to the sucrose in a water-immiscible organic solvent. Several types of products are produced: water-insoluble sucrose ester (ether) copolymers; water-soluble sucrose ester (ether) copolymers; sucrose ester (ether) dimers; and intramolecular, cyclic sucrose esters (ethers). These products can be further varied by using different kinds of acid dichlorides or epoxides that contain different kinds of functional groups.

Abstract: Liposome-encapsulated quinolones and specifically liposome-encapsulated ciprofloxacin dramatically enhances macrophage functions, induces NO production and augments the production of cytokines, rendering the composition an immunoprophylactic and immunotherapeutic agent with unique clinical potential. Liposome-encapsulated ciprofloxacin and other quinolones could be extremely useful in antimicrobial, anticancer and AIDS therapies. In such cases, the immunological status of the patient is often compromised or suppressed, making them susceptible to microbial infections and to the development of tumor growth. Selective augmentation of cellular immunity by activation of the microbicidal and tumoricidal activities of macrophages, induction of NO and cytokine production could be of primary importance to such patients in terms of protecting them against microbial infections and inducing their cellular host defense to tumor cells.
