The first skin-flap procedures were performed in Mongolia by a team of Chinese doctors ( Chenod, Chen)who treated children with burn injuries in the 1950s. The field of plastic surgery was further developed through assistance from the former Soviet Union and is now widely practiced by a number of surgeons around the *** recent years, the fast evolving field of plastic surgery in Mongolia has created a need for clear and consistent system for the classification of various plastic materials. A team of Mongolian surgeons at the National Hospital for Traumatology, Orthopedics, Rehabilitation and Teaching Research have completed a research programme aimed at adopting a leading classification system that can facilitate effective communication between plastic surgeons. This requires the chosen system to be in line with modern trends in plastic surgery and the established international *** a result of extensive research and analysis, they have developed a customized version of Vasiliev's classification that focuses on formulating general principles of the description of plastic materials based on their functional characteristics. The main reason for this selection is its similarity with existing Mongolian standards as well as its principles that contain important implications for surgery.

The mechanical properties of composites prepared from wood flour and thermoplastic blends were investigated. Thermoplastic mixtures of polypropylene (PP) and high-density polyethylene (HDPE) and polystyrene (PS), virgin or recycled, were mixed with wood flour in a high speed blender and then extruded by a specially designed twin/single screw extruder system to form wood-flour/thermoplastic-blends composites (WTBCs). Comparative studies were made to evaluate the effectiveness of the two modification methods of the thermoplastic blends, the one of the addition of maleic anhydride grafted styrene-ethylene-butylene-styrene block copolymer (SEBS-g-MAH) as compatibilizer and the other of blend grafting of maleic anhydride (MAH) using dicumyl peroxide (DCP) as initiator by reactive extrusion. The results showed that the impact properties of WTBCs using SEBS-g-MAH as compatilizer were better improved than that of the blend grafting. However, adverse results were observed on the tensile and flexural properties of the corresponding WTBCs. The mechanical properties of WTBCs prepared from recycled plastic blends were poorer to some extent than that from virgin plastic blends in general, especially in elongation break. The morphology of WTBCs breaking section was analyzed by scanning electron microscopy (SEM) and the results showed that a good interfacial adhesion between wood flour and polymer matrix was observed with both of the two modification methods. However, by blend grafting of adding DCP as initiator and MAH as monomer, a better interfacial bonding between wood and plastic matrix was obtained than that of the addition of SEBS-g-MAH. Blend grafting can be considered as a potential way of increasing the interfacial compatibility of different plastics and between plastic blends and wood.
