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 device for concentrating 99mTc pertechnetate and a method thereof are disclosed. The device includes a concentration device, a control device and a central processing unit. The concentration device is for concentrating 99mTc pertechnetate, the control device connects with each members of the concentration device, and the central processing unit is used for saving an automatic control program. The automatic control program is run by the central processing unit so as to detect and monitor weight as well as activity of the concentrated 99mTc pertechnetate. Due to the automatical control, the concentration quality and production efficiency of the 99mTc pertechnetate are improved. Moreover, the radiation dose received by users is reduced.
