    Abstract: 본 발명은 혈관이 협착된 경우 좁아진 혈관을 넓히기 위하여 사용하는 스텐트(stent)에 혈관의 산화를 방지하기 위하여 혈관 황산화 물질인 치옥트산을 코팅하는 방법에 관한 것으로, 특히 스텐트의 재질이 코발트 크롬 합금인 경우, 기능기를 함유한 고분자 박막을 피복할 수 있는 플라즈마를 사용하여 치옥트산을 코팅할 수 있도록 하는 방법을 제공함으로써 스텐트 시술 후 혈관의 재협착율을 저하시킬 수 있도록 한 것이다.

    Abstract: PURPOSE: A gene delivery system for transferring a target gene to cells is provided to enable stable delivery of the gene delivery system to an organism and to effectively suppress the expression of a specific disease gene. CONSTITUTION: A gene delivery system for transferring a target gene to cells is complexed by ionic interaction through mixing the target gene with polyethylene imine of Branched polyethylenimine cross-linked via disulfide bonds(ssPEI). The target gene is siRNA(small interfering RNA), an antisense molecule, an antagonist, ribozyme, an inhibitor, a peptide, or a small molecule. The target gene is siRNA which is specific to Akt gene. The target gene is fixed on a support. The support is a stent coated with hyaluronic acid or collagen on the surface.
