A method of preparing a .sup.64Cu-BaBaSar-RGD.sub.2 solution is provided. The method includes lyophilizing a solution of BaBaSar-RGD.sub.2 and adding a .sup.64Cu solution to the lyophilized BaBaSar-RGD.sub.2.

This invention relates to a ceramic module for assembly into a therapeutic device for treating a human or animal body with irradiation of far infrared radiation and low dose ionizing radiation based on radiation hormesis effect. More specifically, the invention relates to a ceramic module that simultaneously emits far infrared radiation within 3-16 μm wavelength spectrum and ionizing radiation at a specific dose rate in the range of 0.1-11 μSv/h (micro-Sieverts per hour). Said ceramic module may be used alone or serve as components of a therapeutic device for increasing physiologic performance, immune competence, health, and mean lifespan of human or animal.

This invention relates to a Kit formulation to prepare a radioactive, bone-seeking, pharmaceutical drug that has high radiochemical purity (RCP) in a fast, facile and reproducible process. The Kit has at least two vials and a two-part buffer system with instructions on how to make the drug formulation in a radiopharmacy. The drug formulations of this invention can be conveniently and reproducibly prepared with better delivery of the drug to mammals, better radiochemical purity of the formulation for use in treating a mammal having bone pain, one or more calcific tumors or needing bone marrow suppression or bone marrow ablation.
