    INVIVO BIOCOMPATIBILITY OF AN ALIPHATIC CROSS-LINKED POLYURETHANE IN RABBIT
    (JOURNAL OF BIOMEDICAL MATERIALS RESEARCH, 1991)
    A cage implantation technique has been adopted in a rabbit animal model to investigate the biocompatibility of an aliphatic crosslinked polyurethane based on hexamethylene diisocyanate (HDI). In this study, four cages are represented; the cage containing the candidate polyurethane material, biomedical grade polyurethane (Tecoflex), the commercial grade polyvinylchloride (PVC), and an empty cage which were implanted subcutaneously in rabbits. Exudates were aspirated from these cages at 4, 7, 14, and 21 days postimplantation. Exudates were analyzed for variations in proteins, cell counts, and extracellular enzymes. Results with the four types of cage implants showed that the candidate polyurethane caused an inflammatory response comparable to that caused by medical-grade Tecoflex and the empty cage control.

    LIPOPROTEIN ADSORPTION ONTO MODIFIED CHITOSAN BEADS - PRELIMINARY-STUDY
    (BIOMATERIALS ARTIFICIAL CELLS AND IMMOBILIZATION BIOTECHNOLOGY, 1993)
    Amoung the currently used LDL - apheresis techniques selective removal seems to be a better option. We have made a preliminary study on adsorption of LDL onto modified and bare chitosan and PVA beads. It seems that bare chitosan itself maybe an exellent adsorbent system for LDL. Further detailed studies are required to examine the specificity and selectivity in adsorption.
