Abstract
Poly(D,L-lactide) (PDLLA) was synthesized by ring-opening polymerization of D,L-lactide. Non-woven PDLLA matrices were prepared by an extrusion/winding process. The process conditions were optimized and the surfaces of these matrices were modified by glow-discharge treatment and/or glutaraldehyde incorporation for immobilization of elastin-derived proteins (ESP) to the matrix to increase the biocompatibility and also to improve the bioactivity of the matrix. Glow-discharge conditions were optimized. Ethylene diamine (EDA) and Ar were used as the active monomers in the plasma phase. When EDA was used, the glow-discharge treated PDLLA matrices were first allowed to be reacted with glutaraldehyde, although, when Ar used, the treated matrices were used directly for ESP immobilization. The higher degree of immobilization was obtained for EDA and glutaraldehyde. The ESP-incorporated PDLLA matrices were further treated with elastin by cross-reaction of the ESP molecules on the matrix surfaces with elastin. Scanning electron microscopy (SEM) studies showed that ESP were homogeneously deposited the surface of the matrix.

Abstract
A novel ficolin-related gene was isolated from the mouse liver lambda ZAPII cDNA library. The protein encoded by this gene consists of both collagen- and fibrinogen-like domains, which are common features of the ficolin family, and was named mouse ficolin-A. The amino acid sequence of mouse ficolin-A is 60.2, 59.8, 59.8, and 59.6% identical to those of porcine ficolin-alpha, -beta, human ficolin-1, and EBP-37/P35, respectively. Northern blot analysis showed that mRNA of mouse ficolin-A is highly expressed in liver and spleen. Immunoblot analysis using an anti-mouse ficolin-A antiserum showed that mouse ficolin-A is a plasma protein with binding activity to elastin and GlcNAc.

Abstract
Specific extracellular matrix molecules and growth factors (GFs) with angiogenic properties could be combined with biomaterials to enhance angiogenesis and subsequently tissue ingrowth through the wall of the porous structure. In this study, composite fibrin matrices containing hyaluronic acid (HA), fibronectin (FN) and/or fibroblast growth factor-1 (FGF-1), FGF-2 and an endothelial cell growth supplement (ECGS) were adsorbed onto Dacron meshes which were then implanted subcutaneously in mice. The release from the implants and the tissue distribution of implanted GFs were determined in vivo using radiolabelled FGF-2. Angiogenesis was quantified by counting the number of capillaries present in each Dacron histological serial section. Radiolabelled GF was rapidly released from matrices and was absent from them by day 28. A very low percentage of the implanted radiolabelled GFs was found in the kidneys and livers of the animals. The number of microvessels formed within fibrin-impregnated samples was increased in the presence of HA and ECGS at 14 d and of FN and ECGS or FGF-2 at 28 d. FGF-1 had no direct effect on angiogenesis in our model. These results indicate that enhancement of vascularization within prosthesis mesh may be achieved by using fibrin as a support for angiogenic molecules such as HA, FN and FGFs.

Abstract
The purpose of this investigation was to test clinically the efficiency of a recently described bioabsorbable matrix as a guided tissue regeneration membrane. This matrix was prepared from an original reaction between elastin and fibrin monomers and is now extensively used in several domains of surgery. The study group was composed of 26 patients, with a total of 35 lesions (22 intrabony defects, 8 Class II furcations and 5 Class III furcations) presenting moderate to advanced adult periodontitis. After initial therapy, measurements were made with a calibrated periodontal probe. Probing depth (PD) and gingival margin location (GM) measurements were taken twice: immediately before surgery and after 6 months before re-entry. Clinical attachment level (CAL), vertical osseous level (VOL) and alveolar crest location (AC) measurements were taken during surgery and after 6 months with re-entry procedures for all the patients. Color change of the gingival margin was only observed in 4 defects and device exposure occurred in the proportion of 2 out of the 35 defects. No foreign body reaction was observed in any case. At the intrabony defects mean PD reduction was 5 mm (P < 0.001), and mean gain of CAL was 4 mm (P < 0.001). Mean VOL was 4.3 mm (P < 0.001), mean gingival recession was 0.9 mm (P < 0.05) and mean AC was 0.2 mm (NS). At the Class II furcation defects the mean PD reduction was 4.5 mm (P < 0.001), mean gain CAL vertical was 3.2 mm and CAL horizontal was 4.5 mm (P < 0.001). Gingival recession averaged 1 mm (NS). A complete closure was observed in 2 out of the 8 defects. At the Class III furcation defects the mean PD reduction was 3.6 mm (P < 0.05) and mean CAL-V gain was 1.5 mm (P < 0.02). However the 5 sites showed no horizontal attachment gain and none were unchanged. A very low gingival recession, gingival reaction, crestal bone loss, and device exposure occurred during this study. This preliminary study suggests that the use of a biosynthetic barrier may have beneficial effects in the treatment of intrabony defects and Class II furcation defects. Randomized controlled trials are necessary to evaluate the efficacy and safety of this bioabsorbable membrane in periodontal therapy.

Abstract
Experiments leading to the conception and development of a new artificial connective matrix based on collagen-elastin-fibrin associations are presented. Preliminary evaluation of this biomaterial as an artificial tympanic membrane is described. Morphological evaluation was performed by histopathological and scanning electron microscopic studies. Biocompatibility was documented by subcutaneous implantation and experimental grafting in rabbits was performed with histopathological studies of the tympanic grafted membranes. The positive results obtained in this experimental study enable future studies in humans to be prepared.

Abstract
Titanium nitride (TiN) is regarded as a potential biomaterial for blood-contact applications. Its in vitro haemocompatibility has been evaluated already and gave promising results. The purpose of this study was to continue studying its 'biological' behaviour through an ex vivo evaluation. The material was a physical vapour deposition elaborated TiN coating and the phenomena observed were leucocyte adhesion and albumin and fibrinogen adsorption. These ex vivo results were compared with in vitro results obtained previously. Two reference medical grade silicone elastomer and three TiN arterio-arterial extra-corporeal circuits were tested. No leucocyte was retained by TiN, as in in vitro experiments; the ex vivo fibrinogen adsorbed quantity was higher and albumin adsorption was about the same in in vitro and in ex vivo situations. TiN can be considered as a suitable blood-contacting material.

Abstract
A new original artificial connective matrix mainly made of elastin and fibrin-like product is used to reinforce damaged tissues and to close and restore a loss of substance in several domains of surgery: all sites in the digestive system and urinary tract; besides, it can substitute for the pericardium in iterative heart operations. In all cases, the original tissue is restored ad integrum while the biodegradable material disappears completely, without any complications.

Abstract
The elasticity, mechanical strength and permeability of a new biomaterial made of elastin and fibrin were investigated. It was shown that gamma-irradiation to sterilize the product, and sulphur derivatives (Merceptyl, thiourea, cystein) working as reticulating agents modified these properties. Depending on whether or not the biomaterial needs to be stiff, strong or elastic both physical processes could intervene separately or together. The good permeability of this material allows it to be used in several surgical fields as a true artificial connective matrix.

Abstract
Monomers of fibrin generated by thrombin from fibrinogen reacted with elastin to give a new addition product or adduct. Adduct formation resulted from a covalent bond between fibrin monomers and elastin. The kinetic studies of this reaction confirmed that the adduct was formed before fibrin precipitated to produce the clot. The reaction depended on elastin, fibrinogen and thrombin concentrations. When thrombin-induced and reptilase-induced fibrin were compared, it became obvious that fibrin monomers did intervene more commonly as Des AA-fibrin than as Des AA.BB-fibrin. The adduct synthesis was completely inhibited by 150 microM of the peptide Gly-Pro-Arg-Pro which was previously known to stabilize the fibrin monomers and consequently to inhibit the polymerization completely. It is shown that FXIII could intervene directly in the reaction where homological quality of elastin (human versus bovine) and purity of thrombin were other important factors.
