摘要:
The present invention relates to a biochip for the detection of phosphorylation and a method for measuring phosphorylation using the same, more precisely a biochip integrated with the substrate of kinase and a kit for measuring phosphorylation comprising the biochip and a radio-labeled co-factor, and a method for measuring phosphorylation using the same. The kit for the detection of phosphorylation of the present invention facilitates simple and fast measurement of phosphorylation with a minimum amount of a sample, compared with the conventional method using an antibody, because it uses a radioisotope. This chip and kit can be effectively used for the analysis of kinase activity since this method favors fast mass analysis.

Disclosed herein is a method for the preparation of radioisotope-labeled compounds using CNT. It comprises filling the carbon nanotube with a radioisotope; and labeling a physiologically active material with the radioisotope charged in the carbon nanotube. Taking advantage of CNT, the method can prepare a radioisotope-labeled compound invention at a high yield and in a simple manner. Also, the radioisotope, when remaining unreacted, can be recovered by the filtration of the CNT, thereby achieving the prevention of radioactive contamination and the reduction of radioactive waste. Further, the radioisotope-labeled compound is useful as a contrast medium for imaging the hepatobiliary system.

Disclosed relates to organic germanium nanocolloids, to which technetium-99m (99mTc), a radionuclide, is labeled, method of the same, and a spleen-imaging agent including the same. According to the invention, 99mTc-labeled organic germanium nanocolloids having high labeling efficiency and stability can be provided. Moreover, since the 99mTc-labeled organic germanium nanocolloids of the invention are accumulated in the spleen considerably higher than the conventional spleen-imaging agent, it is possible to use the 99mTc-labeled organic germanium nanocolloids of the present invention as a therapeutic radiopharmaceutical for the spleen imaging.

Disclosed herein is a method of preparing a 188Re-tricarbonyl complex for radiopharmaceutical use and of preparing a precursor thereof, and a contrast agent using the same. Particularly, this invention provides a method of preparing a 188Re-tricarbonyl precursor by reacting perrhenate with borane-ammonia (BH3.NH3), potassium boranocarbonate (K2[H3BCO2]) and phosphate in the presence of borohydride exchange resin as a reducing agent, and a method of preparing a 188Re-tricarbonyl complex by reacting the 188Re-tricarbonyl precursor with a ligand. According to the method of this invention, the borohydride exchange resin is used as a reducing agent and as an anion scavenger, thereby obtaining the 188Re-tricarbonyl precursor and complex having high radiolabeling yield and high purity. In addition, the 188Re-tricarbonyl complex can be used as a contrast agent having excellent plasma stability.

Disclosed is a herbal composition comprising a first hot-water extract from a mixture of the plants Angelicae gigantis Radix, Cnidium officinale Makino and Paeonia japonica Miyabe et Takeda at an equal weight ratio, and a polysaccharide fraction as a precipitate formed by adding ethanol to a second hot-water extract from a mixture of the plants Angelicae gigantis Radix, Cnidium officinale Makino and Paeonia japonica Miyabe et Takeda at an equal weight ratio. The herbal composition of the present invention is effective in improving the anticancer activity, immune response and hematopoiesis of the body, and protecting the body from oxidative damage. Therefore, by stimulating the recovery from the damage to the immune function and hematopoietic function, often occurring during chemotherapy and radiotherapy, and inhibiting oxidative damage, the herbal composition can be applied for the prevention of the side effects of cancer therapy, as well as for the prevention of various degenerative chronic diseases and the improvement of the health of the weak and the elderly.
