A simple, biocompatible system and procedure for generating nitric oxide (NO) is described. A mixture of powdered sodium nitrite, ascorbic acid, and maleic acid (or another organic acid of adequate strength) immediately generates nitric oxide (NO) on treatment with water. To slow down the NO generation, one may prepare an ointment from a nonaqueous medium (petrolatum, Vaseline™) and the three powdered ingredients, which on being applied topically on the skin will release NO as water permeates through this medium; alternatively, one may convert the aqueous sodium nitrite solution into a gel with hydroxyethylcellulose (or other gel-forming compound) and combine this gel with another gel obtained from aqueous ascorbic and maleic acids with hydroxyethylcellulose for topical application (on intact skin, burns intra-cavity, burns, intra-cavity, etc.). The two gels may be admixed immediately before use (possibly from a single container with separate chambers and dual nozzle, via pushing or squeezing the two gels through the nozzle), or may be applied in sandwich-like fashion (possibly as a transdermal patch) for further slowing down the delivery of NO.

A composition includes a viscous gel formed from a combination of a biodegradable polymer and a biocompatible solvent. The composition also includes a hydrophilic porogen, which may be incorporated in the viscous gel. The composition may form a porous scaffold in situ.

A wound dressing is provided which is made up of a backing layer, an apertured wound facing layer and an intermediate absorbent layer comprising fibers of material which upon contact with moisture will form a gel. The intermediate layer also includes a non-gel forming component, e.g., another fibrous material which can support the formed gels. The backing layer also has a water transmission rate which is greater than its moisture vapor transmission rate.

Also described are methods and materials that can be used to prepare the malleable medical materials.

A tear replacement solution that contains at least one water-soluble fluorosurfactant, water and a non-polar component, preferably in gel form, and a method for the external treatment for the eye of an mammal by applying the tear replacement solution to the eye, preferably by placing in the conjunctival sac.

Disclosed are oral care compositions, particularly thickened dentifrices in liquid, paste or gel form comprising a binding / thickening system that also function effectively as humectant agent thereby replacing a significant portion or all of traditional humectant components such as glycerin, sorbitol and other polyols. The binding / thickening system comprise select carrageenans that provide a water viscosity of at least about 20 mPa·s in a 1.5% solution at 25° C. and effective water-binding capacity to prevent significant water loss from the composition when exposed to air to cause unacceptable drying out. For example, the water-binding capacity of the carrageenan must be effective such that there is no more than about 0.75% water loss from a dentifrice composition when exposed to air for 30 minutes at room temperature conditions and 50% relative humidity. The present dentifrice compositions exhibit increased dispersibility in saliva during use, which provides for increased contact time of the composition with the user's teeth and oral cavity tissues such that the active dental agents contained therein are more rapidly available to effect their beneficial activity.

A fabric comprises first and second webs of gel-forming fiber needled to the first and second sides respectively of a textile fiber scrim. Such fabrics find application as wound dressings, in particular for packing cavity wounds.

The present invention relates to growing and testing microorganisms in a multitest format which utilizes a gel forming matrix for the rapid screening of clinical and environmental cultures. The present invention is suited for the characterization of commonly encountered microorganisms (e.g., E. coli, S. aureus, etc.), as well as commercially and industrially important organisms from various and diverse environments (e.g., the present invention is particularly suited for the growth and characterization of the actinomycetes and fungi). The present invention is also particularly suited for comparative analysis of phenotypic differences between cell types, including strains of microorganisms that have been designated as the same genus and species, as well as other cell types (e.g., mammalian, insect, and plant cells).

The invention relates to a biocolloid hemostatic prepared by aldehyde-modified sodium alginate and amine-modified gelatine. Sodium alginate and gelatine as raw materials; according to ratio, aldehyde-modified sodium alginate solution with the concentration of 5-25% and the same volume of amine-modified gelatine solution with the concentration of 5-40% are mixed; sodium alginate is modified by aldehyde through sodium periodate oxidation; and then gel is obtained by mixing with gelatine modified by ethanediamine. The adopted gelatine and sodium alginate are safe and stable, have good biocompatibility and can be absorbed and degraded by organism. Gel is rapidly formed through Schiff base reaction of aldehyde-modified sodium alginate and amine-modified gelatine, and the gel has the same gel-forming time as fibrin glue but better adhesion property and adhesion strength, can be acted on any part of body through simple local spraying or injection, and can be used as substitute product of fibrin glue.
