摘要:
A radioactive material for inhibiting cancer and a preparation method thereof are disclosed. The radioactive material for inhibiting cancer is M-SOCTA-Z and M is a radioactive nuclide such as 188Re or 99mT while Z is protein or peptides having amino acid with NH or NH2 group. The preparation method of the radioactive material for inhibiting cancer includes steps of: reacting SOCTA with protein or peptide. Ester (—COOR) in SOCTA reacts with amines (—NH, —NH2) in protein or peptide to form peptide bond. Thus SOCTA-protein or SOCTA-peptide complex is produced. Then these SOCTA-protein complex reacts with radioactive nuclide M so as to generate M-SOCTA-protein or M-SOCTA-peptide. In an embodiment of the present invention, monoclonal antibody Herceptin is applied to bind with SOCTA and in combination with radiation-based therapy, effects of cancer treatment (such as breast cancer) are enhanced.
摘要:
A radioactive material containing chitosan for inhibiting cancer and a preparation method thereof are revealed. The adioactive material containing chitosan is formed by using SOCTA chelating agent to connect chitosan and radionuclides such as 188Re, and Tc-99m etc. The preparation method of the radioactive material containing chitosan includes the steps of: prepare SOCTA-Chitosan compound; and prepare M(radionuclide)-SOCTA-Chitosan compound. By biocompatibility and clotting in alkaline environment of human blood of chitosan, the radioactive material containing chitosan is injected into cancer and staying there for a long time so as to achieve effectively treatment.
摘要:
A radioactive mixture and a manufacturing method thereof are disclosed. The radioactive mixture (188Re-MN/Lipiodol mixture) is formed by chelating reaction of MN series compounds that are amine-amide-disulfide amine quadric-dentate chelate ligands with TcO4−/or ReO4−, and then dissolved in Lipiodol. Moreover, the 99mTc/or 188Re of the TcO4−/or ReO4− avoids bone marrow injuries caused by free 90Y. By the feature of the Lipiodol that stays in liver tumors for a long period, the radioactive mixture is applied to treat liver cancers by injection so that injuries caused by surgical operations can be prevented. 188Re-MN/Lipiodol is used for liver cancer, breast cancer or other solid tumors treatment. Re-188 MN or Re-188 MN/Lipiodol can be mixed with anticancer drugs, hydrogel, liposome, micelle or other nano-particles to form the multifunctional therapeutic modality.

摘要:
The invention relates to a method of making a grinding disk, comprising the steps of: providing a cap; providing an abrasive part; placing the cap on the abrasive part to form an assembly; holding the assembly and injecting a molding material into a space between the cap and the abrasive part and into the abrasive part to bond the cap and the abrasive part. A grinding disk made by the method is also disclosed.
摘要:
A process of evaluating blood-brain barrier permeability of a stroke rat by using fluorescent substance is disclosed. This process uses an Evans blue dye having spontaneous fluorescence properties, in combination with the use of a new non-invasive in vivo imaging system (IVIS), to obtain fluorescent signals so as to assess the change in the blood-brain barrier permeability of rodents after a cerebral artery stroke model surgery. In operation, an Evans blue dye is injected into a stroke rat of middle cerebral artery occlusion model. A non-invasive in vivo imaging system is used to detect the fluorescence distribution of the whole brain, and obtain images combined by the fluorescence images and optical images for the whole brain tissue. Thereby, the change in the blood-brain barrier permeability of the stroke rat can be completely realized.
