Abstract: Polyionic derivatives of cyclodextrins and methods for preparing these derivatives are provided in which a polyionic derivative of cyclodextrin is combined with a growth factor, preferably a heparin binding growth factor. These compositions are of low solubility and are applied directly to the location of a wound. By virtue of the low solubility, the compositions remain in place at the site of application and slowly release growth factor. In an alternative embodiment, the cyclodextrin derivatives are administered in the absence of growth factor and are used to absorb growth factor present in the body at the location of the wound in order to prevent overstimulation of the wound response.

Abstract: Reaction at the interface of an organic solution containing an acidic reactant and an aqueous alkaline solution containing nonreducing carbohydrates such as sucrose, sugar alcohols, cyclodextrins, and polysaccharides imparts a specificity to the reaction for one or more of the primary alcohol groups of the carbohydrate reactant. The resulting activated, nonreducing carbohydrate intermediate can then be converted to a series of substantially pure, low molecular weight reaction products, including a sucrose trimer and dianhydrosucrose, and to a series of substantially pure, higher molecular weight reaction products, including 6-O-sucro cyclodextrins and poly-6-O-sucro amylose.

Abstract: This invention relates to treatment of traveller's diarrhea, including diarrhea caused by enterotoxigenic Escherichia coli (ETEC), using an oligosaccharide-containing composition. The composition contains an oligosaccharide sequence covalently attached to a pharmaceutically acceptable solid, inert support through a non-peptidyl compatible linker arm. The oligosaccharide-containing composition binds E. coli heat-labile toxin (LT). More specifically, the invention concerns neutralization and removal of LT associated with traveller's diarrhea.
Abstract: A diagnostic method for assessing how a hypercholesterolemic person's serum cholesterol level will respond to a low total fat and saturated fat diet. The method involves defining a target cholesterol level, measuring a baseline level, feeding for a term of 3-25 days a NCEP Step I diet of which at least 50% of the caloric intake is provided by a fortified, low-fat nutritional product, and comparing the post term cholesterol level to the defined goal to see if the target is met. If the target is met, the person is predicted to respond to dietary intervention. If the target is not met, the person is deemed a non-responder and is considered for drug therapy. A fortified, low-fat nutritional product supplies in about 1000 kcal (i) 100% of the adult RDI for vitamins and minerals; and (ii) total fat, saturated fat and cholesterol levels that are at or below the levels specified for a Step II diet.
Abstract: An oligomer comprised of repeat units of beta glucosamine exhibits broad antifungal activity. The oligomer preferably has a molecular weight in the range of 4,000-18,000 dalton, and may be partially acetylated. These materials are highly effective against a variety of fungi including various species of Candida.
Abstract: This invention provides a novel chromanol glycoside which is a water soluble antioxidant excellent in heat and pH stability and production method thereof. It is a chromanol glycoside represented by the general formula (1): ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, and R.sup.4 independently are a hydrogen atom or a lower alkyl group, R.sup.5 is a hydrogen atom, a lower alkyl group, or a lower acyl group, X is a monosaccharide residue or an oligosacoharide residue, providing the hydrogen atom of the hydroxyl group of saccharide residue may be substituted by a lower alkyl group or a lower acyl group, n is an integer in the range of 0 to 4, and m is an integer in the range of 1 to 6.
Abstract: The invention provides a method of preparing water-insoluble polysaccharide sponges, and sponges obtained by means of the method. The method comprises: (a) providing an aqueous solution of a soluble polysaccharide; (b) freezing the solution; (c) treating the frozen solution with a water-miscible organic solvent such as isopropanol to effect solvent exchange for the water in the frozen solution; and (d) drying the resulting polysaccharide material. The organic solvent contains a cross-linking agent such as calcium chloride to render the polysaccharide water-insoluble in the solvent-exchange step (c). The resulting materials are more conformable and less friable than freeze-dried polysaccharide sponges.
Abstract: The invention discloses the discovery that a pharmaceutical composition containing complex carbohydrates and natural or synthetic essential oils can work effectively as a topical pharmaceutical composition. Such pharmaceutical compositions reduce inflammation, assist in wound healing, protect against bruising, relieve itching, relieve pain and swelling and treat topical bacterial infections such as acne and decubitus ulcers. Such pharmaceutical compositions can be administered to mammals including humans. Also included in this invention are methods to deliver topically applied macromolecules into the tissue of mammals and methods of blocking the adhesion cascade.
Abstract: Small pore silicas serving as the inert core support in chiral stationary phases show a surprising increase in column capacity relative to conventional chiral stationary phases having large pore silicas as the inert core support. This affords increased productivity and lower overall costs for chiral resolutions using a chiral stationary phase as adsorbent and an achiral liquid as eluant.
