Medicine fibrous materials

Using the natural polymer, hydrated cellulose, alumina nanocrystalline materials were successfully fabricated. The structure simulates the complex architecture of the origin biological matrix. They were composed of oxide nanograins, mesopores, and the branched system of capillars. These nanostructured alumina fibrous material possess the high absorption ability and may be used as drainage of purulent wound in medicine. 

This research work focuses on process characteristics of pol5mier solutions, such as viscosity and electrical conductivity, as well as the parameters of electrospiiming using poly-3-hydroxybutyrate modified by titanium dioxide nanoparticles, which have been optimized. Both physical-mechanical characteristics and photooxidation stability of materials have been improved. The structure of materials has been examined by means of X-ray diffraction, differential scanning calorimetry (DSC), IR-spectroscopy, and physical-mechanical testing. The fibrous materials obtained can find a wide application in medicine and filtration techniques as scaffolds for cell growth, filters for body fluids and gas-air media, and sorbents. 

When woody plants once covered most of the earth s surface, they provided not only food, warmth, and shelter, but many of the needs of defense, medicines, culture, and simple pleasures. Some needs could be readily satisfied by using minor forest products such as resins for caulking boats, for use in torches, or for providing rigidity in the attachment of spear, arrow, or axe-heads to the shaft before the joints were finally lashed with fibrous material (24). Such resinous products could be provided by a number of sources and a few trials would reveal their effectiveness. Other materials, such as kinos or tannin extracts, when used as astringents for the treatment of diarrhea, would require a more sophisticated knowledge.

Cellulose and its derivatives are used in a number of food products to modify those foods in different ways (e.g., as a thickener, stabilizer, or tex-turizer). The fibrous form is a basic material that is used to make both textiles and paper. Cellulose is also used to make nitrocellulose (an ingredient in explosives and lacquers) and as a binder in the manufacture of medicinal tablets. SEE also Fibers Polymers, Natural Polysaccharides.

The conducted investigations proved that the presented method of fibrous nanocomposite materials production is suitable for materials for regenerative medicine used to fill bone losses and stimulation of accelerated bone regeneration.
