Abstract: A manufacturing and separating device and a method for oily radioactive substances provide an automatic synthesis box to minimize the man-made errors during the manufacturing, such that mass production for the oily radioactive substance can be possible, the radiation exposure time of the manufacturing staff can be reduced, and the radioactivity of the final products can be detected. The manufacturing and separating device includes a first reaction material bottle, a first heating device, a gas pump, a first flushing material bottle, a second flushing material bottle, a purifying device, a first transmission unit, a temperature-controlled temporary storage tank, a filter, a first collection bottle, a second collection bottle, a plurality of valves and a control unit.

Abstract: A thermosensitive hydrogel for coating radioisotopes and chemotherapeutic agents to treat cancer and a method for preparing the same are revealed. The anticancer drugs such as radiopharmaceuticals or chemotherapeutic agents are coated with the hydrogel formed by PCL-PEG-PCL. By the feature of the hydrogel body that changes from liquid phase at low storage temperature to gel form at body temperature, not only the anticancer drugs can be injected into the human body and reaching the treatment site smoothly but the treatment time of brachytherapy is also extended. Thus the side effects of cancer therapy are significantly reduced.

Abstract: 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.

Abstract: 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.

Abstract: 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.
