Therefore, it is possible to carry out minimally invasive surgery during bone fracture surgery, thereby enabling simple and quick bone fracture surgery for a speedy recovery.
摘要:
The present invention relates to a magnetic resonance imaging (MRI) contrast agent including a gadolinium complex, more particularly to a DO3A-tranexamic acid or its ester compound, which is represented by the Chemical Formula 1. A DO3A-tranexamic acid or its ester compound may be prepared according to the present invention and a gadolinium complex may be prepared using the compound. An MRI contrast agent including the gadolinium complex prepared according to the present invention as an active ingredient has higher relaxivity as compared to the currently commercially available contrast agent. In addition, the MRI contrast agent according to the present invention has bifunctionality of liver-specific and blood-pool contrasting effect. Accordingly, since the MRI contrast agent including the gadolinium complex according to the present invention satisfies the key properties required for a contrast agent for MRI, it can be widely used as an MRI contrast agent and can provide enhanced contrasting effect as compared to the existing contrast agent.

The present invention relates to a target-aiming drug delivery system for diagnosis and treatment of cancer containing liposome labeled with peptides which specifically targets interleukin-4 receptors, and a manufacturing method thereof. The liposome which contains anticancer drugs labeled with IL4RPep peptides prepared in accordance with the present invention can deliver drugs to cancer cells in which IL-4 receptors are overexpressed by IL4RPep peptides which specifically bind to IL-4 receptors, and the drug delivery can recognize cancer cells specifically by a label. Thus, IL4RPep peptides can increase the effect of drugs only on cancer tissues and at the same time significantly reduce the side effects on normal tissues, which makes possible in vivo(molecular) imaging and early diagnosis of tumors. Therefore, the liposome which contains anticancer drugs labeled with IL4Pep peptides of the present invention can be applied, as the target-aiming drug delivery system, effectively to the diagnosis and treatment of cancers.
摘要:
Provided are a contrast agent for optical imaging, a use thereof and an apparatus using the same. The contrast agent for optical imaging of the present disclosure allows optical imaging without requiring a fluorophore or a luminophore. As a result, the optical images can be acquired without changing the physicochemical properties of a substrate. The contrast agent for optical imaging of the present disclosure may be used as an optical/nuclear bimodal imaging contrast agent for many applications, and allows radiation therapy as well as monitoring of a therapeutic effect thereof through optical imaging at the same time. Further, when a fluorophore is attached thereto, light emission may be enhanced without energy input from outside since light is emitted from the fluorophore, thereby increasing luminescence intensity and improving tissue penetration.
