    • A method for injection of an imaging contrast into a patient, includes: a. in a first phase, injecting a fluid having a first concentration of contrast agent for a first period of time; and b. in a second phase, injecting a fluid having a second concentration of contrast agent for a second period of time. The osmolarity of the second phase is higher than the osmolarity of the first phase. In several embodiments in which the contrast agent of the first phase is of the same composition as the contrast agent of the second phase, the second concentration can be higher than the first concentration. The first phase can, for example, precede the second phase. The method can further include: c. in a third phase, subsequent to the second phase, injecting a fluid having a third concentration of contrast agent for a third period of time. The osmolarity of the third phase is lower than the osmolarity of the second phase. In embodiments in which the composition of the contrast agent of the third phase is the same as the composition of the contrast agent of the second phase, the third concentration can be lower than the second concentration. The fluid injected in the first phase can, for example, be closer to the osmolarity of blood that the fluid injected in the second phase and can even be generally iso-osmolar to blood plasma (for example, within 20% or even 10% or less of the osmolarity of blood plasma of the patient). Likewise, the fluid injected in the third phase can be closer to the osmolarity of blood plasma that the fluid injected in the second phase and can even be generally iso-osmolar to blood.
    • 一种用于将成像对比度注射到患者体内的方法包括:a。 在第一阶段中,将具有第一浓度的造影剂的流体注射第一时间段; 和b。 在第二阶段中,将具有第二浓度的造影剂的流体注射第二时间段。 第二相的渗透压高于第一相的渗透压浓度。 在其中第一相造影剂与第二相造影剂具有相同组成的几个实施方案中,第二浓度可高于第一浓度。 第一阶段可以例如在第二阶段之前。 该方法还可以包括:c。 在第三阶段中,在第二阶段之后,将具有第三浓度的造影剂的流体注射第三时间段。 第三相的渗透压低于第二相的渗透压。 在第三相造影剂的组成与第二相造影剂的组成相同的实施方案中,第三浓度可低于第二浓度。 在第一阶段注射的流体可以例如更接近在第二阶段中注入的流体的血液的渗透压,甚至可以通常与血浆等渗(例如在20%或甚至10%以内) 较少的患者血浆渗透压)。 同样地,注入第三相的流体可以更接近在第二相中注入的流体的血浆的渗透压,甚至可以通常与血液等渗。

    • VEGFR-2 and VEGFR-3 inhibitory anthranilamide pyridinamides, their production and use as pharmaceutical agents for treating diseases that are triggered by persistent angiogenesis, as well as intermediate products for the production of the compounds are described. The compounds according to the invention can be used as or in the case of tumor or metastasis growth, psoriasis, Kaposi's sarcoma, restenosis, such as, e.g., stent-induced restenosis, endometriosis, Crohn's disease, Hodgkin's disease, leukemia; arthritis, such as rheumatoid arthritis, hemangioma, angiofibroma; eye diseases, such as diabetic retinopathy, neovascular glaucoma; renal diseases, such as glomerulonephritis, diabetic nephropathy, malignant nephrosclerosis, thrombic microangiopathic syndrome, transplant rejections and glomerulopathy; fibrotic diseases, such as cirrhosis of the liver; mesangial cell proliferative diseases, arteriosclerosis, injuries to nerve tissue, and inhibition of the reocclusion of vessels after balloon catheter treatment, in vascular prosthetics or after mechanical devices are used to keep vessels open, such as, e.g., stents, as immunosuppressive agents, as a support in scar-free healing, senile keratosis and contact dermatitis. The compounds according to the invention can also be used as VEGFR-3 inhibitors in the case of lymphangiogenesis.
