摘要:
A hydrogel tissue adhesive having decreased degradation time is described. The hydrogel tissue adhesive is formed by reacting an oxidized polysaccharide with a water-dispersible, multi-arm polyether amine in the presence of an oligomer additive, which promotes the degradation of the hydrogel. The hydrogel may be useful as a tissue adhesive or sealant for medical applications, such as a hemostat sealant or to prevent undesired tissue-to-tissue adhesions resulting from trauma or surgery.

A method for treating wounds, comprising providing a dry powder mixture, which when partially hydrated, forms a gel having an osmotic pressure sufficient to achieve and maintain antiseptic conditions in hydrated portions of the gel, the gelled portion comprising a biocompatible polymer, the dry powder being readily wettable by wound secretions; and applying the dry powder to a wound having wound secretions in sufficient excess to produce a self-adherent gel cake having a dry powder surface. The administration may be repeated by administration of the dry powder while wound healing progresses.

Conjugates of an active substance and hydroxyalkyl starch (HAS) are provided herein. The active substance and the HAS are linked by a chemical moiety having a structure according to formula (I) wherein Y is O or S, and X is SH or (F). The conjugate has a structure according to formula (IV) wherein HAS′ is a residue of HAS or a derivative thereof linked to the thioester group, and AS′ is a residue of the active substance or derivative thereof linked to the alpha-X beta-amino group; or a structure according to formula (V) wherein HAS′ is a residue of HAS or derivative thereof linked to the alpha-X beta-amino group, and AS′ is a residue of the active substance or derivative thereof linked to the thioester group, and wherein the group —(C═Y) is derived from the thioester group —(C═Y)—S—R′ and the group HN—CH—CH2—X is derived from the alpha-X beta amino group.
摘要:
The invention relates to a method for the preparation of a hydroxyalkyl starch derivative which comprises reacting hydroxyalkyl starch (HAS) via the optionally oxidised reducing end of the HAS with the amino group M of a crosslinking compound which, apart from the amino group, comprises a specifically protected carbonyl group, namely an acetal group or a ketal group.
摘要:
A method for treating diaper rash, leg ulcers and bed sores using super hydrated bacteriostatic topical preparation with a stable acid pH 5.82, by applying this topical application, which is a mixture of anhydrous lanolin (USP), water, boric acid powder (USP), edible corn starch, white petrolatum, cosmetic grade, and zinc oxide ointment (USP 20% zinc oxide) mixed in a paddle mixer at a temperature of about 100° F. to 107° F. then applying topically, the super hydrated bacteriostatic preparation, at room temperature, on the rash, leg ulcers, or bed sores.
摘要:
The present invention relates to a composition comprising a starch or total dietary fiber which improves the cell viability, specifically, the inventive starch and total dietary fiber isolated from the extract of Gramineae plant and the components therefrom improved the cell viability when the cells were incubated under hypoxic condition, or in the presence of beta-amyloid and 6-hydroxydopamine treatment, as well as prevented and treated myocardiac infarction, cerebral infarction and vascular dementia, or alleviated memory loss, all of which were proven using rats as the respective animal models. Therefore, they can be used as therapeutics or health care food for preventing and treating ischemic diseases or degenerative brain diseases.
摘要:
The present invention provides an enhanced gelling agent composition comprising a mixture of an anionic surfactant and a coupling agent. The invention also describes compositions in gel form comprising: (a) a solvent selected from the group consisting of polar solvents, non-polar solvents and combinations thereof; and (b) a gelling agent in an amount sufficient to impart gelation to the composition, the gelling agent being a mixture comprising an anionic surfactant and a coupling agent. The gels of the invention may be substantially anhydrous or may optionally contain water as part of the formulation.
摘要:
Methods for treating obesity or obesity related disorders are disclosed. These methods include the use of anti-obesity agents directed to the forebrain in combination with anti-obesity agents directed to the hindbrain.
摘要:
A modified starch material for biocompatible hemostasis, biocompatible adhesion prevention, tissue healing promotion, absorbable surgical wound sealing and tissue bonding, when applied as a biocompatible modified starch to the tissue of animals. The modified starch material produces hemostasis, reduces bleeding of the wound, extravasation of blood and tissue exudation, preserves the wound surface or the wound in relative wetness or dryness, inhibits the growth of bacteria and inflammatory response, minimizes tissue inflammation, and relieves patient pain. Any excess modified starch not involved in hemostatic activity is readily dissolved and rinsed away through saline irrigation during operation. After treatment of surgical wounds, combat wounds, trauma and emergency wounds, the modified starch hemostatic material is rapidly absorbed by the body without the complications associated with gauze and bandage removal.
摘要:
The present invention relates to raw materials for foods, pharmaceuticals, and the like, wherein the raw materials can be effective in preventing and ameliorating various lifestyle-related diseases such as obesity and hyperlipidemia, safe, applicable in wide areas, and less deteriorative to texture; and the present invention also relates to a preventive/remedy for obesity, an agent for suppressing fat accumulation in internal organs, an agent for suppressing blood glucose level increase, or a preventive/remedy for diabetes, wherein acetylated starch or starch octenyl succinate is an active ingredient.
