Absorbable synthetic

Aloisture Absorbent Synthetic Paper. Processes for making a water absorbent synthetic paper with dimensional stabihty have been developed by several companies. In a process developed by Mitsubishi Rayon, acrylic fiber is insolubilized by hydra2ine and then hydroly2ed with sodium hydroxide. The paper, formed from 100 parts fiber and 200 parts pulp, has a water absorption 28 times its own weight (96). Processes for making hygroscopic fibers have also been reported in the patent Hterature. These fibers are used in moisture absorbing nonwovens for sanitary napkins, filters, and diapers.

Caprosyn retains 50% tensile strength at 5 days with a near complete absorption (intramuscular) at 56 days (Pineros-Fernandez et al., 2004), the most rapidly absorbed synthetic monofilament suture. Pineros-Fernandez et al. (2004) showed that Caprosyn had a dermal tissue drag force of 54 20 g and stiffness (the amount of suture deflection under a constant weight and suture length, that is, higher amount of suture deflection means less stiff) of 843 106 X 10 N/cm, which was significantly less than that of chromic gut. 

Of analogous metabolic significance are cyclic chains of transformations ending in regeneration of catalytically active components, for example, the Krebs cycle as a whole here OA accepts PU (or an active acetate residue) by condensing with it to isocitrate, and is reconstituted in a chain of reactions, the net result of which is the complete oxidation of PU. Important energy-absorbing synthetic steps are associated with the cyclic...

Anti-adhesive materials have been developed to prevent tissue adhesion by providing a physical barrier between an injured site and the adjacent tissues. Although several non-absorbable synthetic materials such as silicone and PTFE have been shown to be effective, bioabsorbable materials are preferred because of the lack of necessity of secondary surgery to remove non-absorbable materials and the lack of need to consider long-term biocompatibihty such as encapsulation of the material, which will also evoke tissue adhesion. Moreover, non-absorbable synthetic materials have been shown to form adhesions on long-term application [99]. A wide variety of substances and materials have been used over the years. Commercially available anti-adhesive products are summarized in Table 8.7.
