摘要:
The present invention provides a biodegradable medical adhesive or a sealant composition containing an oxidized glycosaminoglycan and a polyamine. The composition of the present invention exhibits improved effects in biodegradation, coating property, gelation time, hemostatic capacity, adhesive force, moisture absorptive capacity and the like, and thus can be applied to various medical uses in which a medical adhesive or sealant can be used, such as biotissue adhesion, filling, coating, adhesion prevention, wound covering, leakage prevention and hemostasis.
摘要:
This document provides methods and materials involved in making and using cross-linked platelet material (e.g., cross-linked lysate material from human platelets such as human platelets obtained from platelet blood collection preparations or platelet apheresis preparations). For example, methods and materials for cross-linking platelet material (e.g., lysate material obtained from human platelets) to form a matrix (e.g. a cell-free tissue scaffold) for wound healing or regenerative medicine or to form conjugates or modified molecules are provided.
摘要:
Methods are provided for treatment of wounds using a complex antimicrobial sorption composition possessing the necrolytic effect for treating the purulent wounds, the trophic ulcers, the wounds, and the infiltrates with the significant necrotic and exudative components represents the silica sorbent with the immobilized drug. Pyrogenic silica is used as a siliceous sorbent, and serrathiopeptidase as a drug.
摘要:
Compositions that include nanoscale structured materials or precursors thereof (e.g., self-assembling peptides) are described. The compositions can include other substances (e.g., a vasoconstrictor). Also described are methods for using the compositions to promote hemostasis, to protect the skin or wounds from contamination, to decontaminate a site upon removal of previously applied compositions that provided a protective coating, and to inhibit the movement of bodily substances other than blood. The compositions are also useful in isolating tissue, removing tissue, preserving tissue (for, e.g., subsequent transplantation or reattachment), and as bulking, stabilizing or hydrating agents. Medical devices that include the compositions (e.g., a stent or catheter), bandages or other wound dressings, sutures, and kits that include the compositions are also described.

摘要:
A hemostat comprises a non-porous patch made of a bio-resorbable tissue compatible material, said patch having a tissue-facing surface and a top surface; an optional hemostatic agent that is disposed on said tissue-facing surface or optionally dispersed throughout said patch or optionally as a separate carrier layer, and at least one aperture or slit that penetrates said patch at least partially from said tissue-facing surface to said top surface.

Meshes for use to control the movement of bodily fluids, such as blood, are described herein. The mesh can be partially or completely biodegradable or non-biodegradable. In one embodiment, the mesh is formed from one or more self-assembling peptides. The peptides can be in the form of fibers, such as nanofibers. The peptides can be assembled prior to formation of the mesh or after the mesh has been formed but before it is applied. Alternatively, the mesh can be prepared from unassembled peptides, which assemble at the time of application. The peptides can assemble upon contact with bodily fluids (e.g., blood) or can be contacted with an ionic solution to initiate assembly.
摘要:
The present invention refers to a composition, comprising hemoglobin or myoglobin, wherein in at least 40% of said hemoglobin or myoglobin the oxygen binding site is charged by a non-O2 ligand, and at least one further ingredient, a method for preparing said composition and the use of hemoglobin or myoglobin charged with a non-oxygen ligand for external treatment of wounds.
摘要:
The invention provides a non-particulate cross-linked poly-ε-lysine polymer. The poly-ε-lysine and cross linker are linked by amide bonds and may the cross linker has at least two functional groups capable of reacting with an alpha carbon amine of poly-ε-lysine. The polymer is suitably insoluble in water and other solvents and is provided in macro form for example a sheet, article or fibre. The macro form polymer is useful in a wide range of applications including wound treatment, as a medical diagnostic comprising a particulate support and a functional material bound or retained by the support and solid phase synthesis of peptides, oligonucleotides, oligosaccharides, immobilisation of species, cell culturing and in chromatographic separation.
摘要:
Formulations and methods are disclosed which are effective to kill or control bacteria in the nares including gram-positive bacteria strains of S. aureus that are antibiotic resistant (MRSA—methicillin-resistant Staphylococcus aureus. A preferred composition comprises one or more medium-chain alcohols (dodecanol), glycerol monoesters (glycerol monocaprylate or glycerol monolaurate), and/or benzoic acid or benzoic acid analog, in a suitable pharmaceutical carrier, preferably an ointment, along with an odorant compound, preferably eucalyptus oil. The formulations and variations of the formulation may also be used on open wounds or lesions as well as intact skin.
