  • Patent number: 5863984
    Abstract: Biomaterials like collagen can be designed for use as scaffolds for connective tissue reconstruction. It is known that proteins conjugated with PEGs exhibit a decrease in their biodegradation rate and their immunogenicity. Different concentrations and molecular weights of PEGs (PEG-750 and PEG-5000) were conjugated by chemical or irradiation means to collagen materials (films or sponges) which were then investigated by physicochemical assays, collagenase assay, fibroblast cell culture and subcutaneous implantation. PEG-conjugation delayed the degradation by collagenase and preserved a normal fibroblasts morphology and confluency in culture. In vivo, the porous structure of non-modified sponges was collapsed by day 15 with few observable fibroblasts between the collagen fibers. In PEG-modified collagen sponges, the porous structure remained stable for at least 30 days. Cell infiltration was particularly enhanced in PEG-750-conjugated collagen sponges.

  • Patent number: 5653999
    Abstract: Carriers for pharmacologic agents comprise nanoerythrosomes, which are vesicles prepared by the extrusion of red blood cell ghosts, the average diameter of these vesicles is 0.1 .mu.m; the daunorubicin was covalently linked to nanoerythrosomes and the cytotoxicity of daunorubicin conjugated to nanoerythrosomes was assessed on P388D.sub.1 cell line; the results indicated that the cytotoxicity of conjugated daunorubicin was higher than the free daunorubicin, similar results were observed on CDF.sub.1 mice bearing grafted P388D.sub.1 leukemia tumors; daunorubicin-nanoerythrosome conjugates had a higher antineoplastic activity than the free bioactive agent.
