    摘要： The present invention describes a synthetic non-viral vector composition for gene therapy and the use of such compositions for in vitro, ex vivo and/or in vivo transfer of genetic material. The invention proposes a pharmaceutical composition containing 1) a non-cationic amphiphilic molecule or macromolecule and its use for delivery of nucleic acids or 2) a cationic amphiphilic molecule or macromolecule that transforms from a cationic entity to an anionic, neutral, or zwitterionic entity by a chemical, photochemical, or biological reaction and its use for delivery of nucleic acids. Moreover this invention describes the use of these non-viral vector compositions in conjunction with a surface to mediate the delivery of nucleic acids. An additional embodiment is the formation of a hydrogel with these compositions and the use of this hydrogel for the delivery of genetic material. A further embodiment of this invention is the use of a change in ionic strength for the delivery of genetic material.

    摘要： One aspect of the present invention generally relates to methods of sealing a wound or tissue plane or filling a void splace. In a preferred embodiment, the wound is an ophthalmic, pleural or dural wound. In certain instances, the compositions used to seal the wound or tissue plane comprises a polyalkyleneimine. In a preferred embodiment, the polyalkyleneimine is polyethyleneimine. Treatment of the polyethyleneimine with a cross-linking reagent causes the polyethyleneimine polymers to polymerize forming a seal. In certain instances, the cross-linking reagent is a polyethylene glycol having reactive terminal groups. In certain instances, the reactive terminal groups are activated esters, such as N-hydroxy succinimide ester. In certain instances, the reactive terminal groups are isocyanates. In certain instances, the polyethyleneimine has a lysine, cysteine, isocysteine or other nucleophilic group attached to the periphery of the polymer. In certain instances, the polyethyleneimine is mixed with a second polymer, such as a polyethylene glycol containing nucleophilic groups. In certain instances, the compositions used to seal the wound or tissue plane are formed by reacting a polyalkyleneimine bearing electrophilic groups with a cross-linking reagent containing nucleophilic groups. In certain instances, the electrophilic groups on the polyalkyleneimine are activated esters, such as N-hydroxy succinimide ester. In certain instances, the compositions used to seal the wound or tissue plane are formed by reacting a polyalkyleneimine bearing photopolymerizable groups with ultraviolet or visibile light. Compositions used to seal the wound which contain PEI or a derivative of PEI are found to adhere tightly to the tissue. Other aspects of the present invention relate to methods of filling a void of a patient or adhering tissue. In certain instances, the methods use a polyalkyleneimine. In a preferred embodiment, the polyalkyleneimine is polyethyleneimine. Another aspect of the present invention relates to a polymeric composition formed by exposing a polyalkyleneimine to an activated polyalkylene glycol. In certain instances, the composition is attached to mammalian tissue.
