An in vivo test for the estimation of blood compatibility of pliable sutures coated with the test polymer was developed. An 18 gauge needle was inserted into the peripheral vein of a dog under general anesthesia and a polymer- coated suture was inserted through the needle into the lumen of the...
An acrylate monomer with a pendant biguanide, N'-4-(2-acryloyl- oxyethyl)phenyl-N5-4-chlorophenylbiguanide hydrochloride (2), when incor porated covalently into cross-linked polyacrylamide matrices was found to hydrolyzed in water to release N1-4-(2-hydroxyethyl)phenyl-N5-chlorophenylbi guanide...
Hydrophilic microspheres, with a diameter of about 2μm, composed of glyceryl methacrylate and methacrylic acid were prepared. The microspheres could be stably stored in dispersed state and demonstrated little non-specific adherance to cell membranes. Luminol-bound microspheres, prepared by...
The rates of uptake of 35S from S(-II) solutions by wine yeasts, Saccharomyces cerevisiae strains R92 and R104 and Saccharomyces chevalieri strain R93, were measured at a variety of solution pH values between pH 3.1 and pH 7.8. A pH effect was observed, the rates of uptake being higher at the...
The recent advances in the preparation, characterization and biomedical appli cations of novel polymeric materials obtained by complexing polyelectrolytes in aqueous solutions are reviewed. A broad definition of a "polymeric complex" was adopted that includes not only stoichiometric and...
