    • The present invention relates to radioisotope-labeled and angiogenesis-promoting protein or peptide-loaded polymeric hydrogel, method for preparing the same, and pharmaceutical composition for preventing or treating ischemic disease comprising same as an active ingredient. The polymeric hydrogel according to the present invention directly labels radionuclides on biodegradable polymers and deposits angiogenesis-promoting protein or peptide when forming hydrogel, thereby angiogenesis-promoting protein or peptide is gradually released while staying in disease region in which polymeric hydrogel is accumulated. Therefore, waste of large amount of angiogenesis-promoting protein or peptide can be prevented; particle amount staying in ischemic diseases region can be quantified by checking bio-distribution using a gamma camera; and therapeutic effects can be predicted. In addition, the present invention releases radiation from disease region, thereby being suitably used for treating diseases such as ischemic disease. Therefore, the polymeric hydrogel according to the present invention can expect therapeutic effects by radionuclides and angiogenesis-promoting protein or peptide at the same time, and enhance therapeutic effects of disease region by quantitatively evaluating accumulation of medicines.
    • 本发明涉及放射性同位素标记和促血管发生蛋白或加载肽的聚合物水凝胶,其制备方法,以及用于预防或治疗缺血性疾病的药物组合物,其含有作为活性成分的缺血性疾病。 根据本发明的聚合物水凝胶在生物可降解聚合物上直接标记放射性核素,并在形成水凝胶时沉积血管生成促进蛋白或肽,从而血管生成促进蛋白质或肽逐渐释放,同时停留在其中积聚聚合物水凝胶的疾病区域中。 因此,可以防止大量促血管生成蛋白质或肽的浪费; 可以通过使用γ照相机检查生物分布来量化留在缺血性疾病区域中的颗粒量; 可以预测治疗效果。 此外,本发明释放疾病区域的辐射,从而适合用于治疗诸如缺血性疾病的疾病。 因此,根据本发明的聚合物水凝胶可以预期通过放射性核素和促血管生成蛋白质或肽的治疗效果同时进行,并通过定量评价药物的积累来增强疾病区域的治疗效果。
