Abstract: The present invention provides a treatment of osteosarcoma by boron neutron capture therapy using boric acid as a single boron drug.

Abstract: Methods of preparing a composition comprising non-ionic, radioactive gold nanoparticles (R-GNPs) are disclosed. The method comprises: a) providing an aqueous composition comprising gold (Au-197) ions in the absence of a template; and b) exposing the aqueous composition in the absence of the template to neutron irradiation to generate the composition comprising the non-ionic R-GNPs. Alternatively, the method comprises: a) providing an aqueous composition comprising gold (Au-197) nanoparticles (GNPs) in the absence of a template; and b) exposing the aqueous composition comprising the GNPs in the absence of the template to neutron irradiation and thereby generating the composition comprising the non-ionic R-GNPs. Compositions that comprises mesoporous silica nanoparticles (MSNs) and non-ionic R-GNPs encapsulated within pores and/or channels and further anchored to the surfaces of the MSNs, and methods of making the same are also disclosed.

Abstract: The present invention relates to the degradation and removal of organochlorine pesticides (OCP) from Chinese herb medicines. In this invention, gamma irradiation is used for the degradation and removal of OCP, such as Pentachloronitrobenzene, Aldrin, Lindane, Heptachlor, Endosulfan-1, Endosulfan-2, o,p?-DDD, p,p?-DDD, p,p?-DDE, and p,p?-DDT from Chinese herb medicines. The method of the present invention requires no chemical reagents, and the application of the method is not limited by the volume and morphology of the Chinese herb medicines.

Abstract: A pharmaceutical composition for boron neutron capture therapy (BNCT), and in particular for BNCT on hepatoma is disclosed. The pharmaceutical composition contains a therapeutically effective amount of triphenylboroxin (phenylboronic anhydride) as a boron source and a pharmaceutically acceptable carrier, such as lipiodol.

Abstract: A nuclear medical drug for localize radiotheraphy of a tumor and methods for its preparation. The drug includes a radioactive ceramic or glass particle having biocompatiblity. Ceramic or glass particles prepared by traditional processes become radioactive particles with pure .beta.-particle-emitting radionuclides after being irradiated with an appropriate flux of neutrons. The radioactive particle with suitable particle size can then be dispersed into a contrast medium for injection or can be implanted by operation.

Abstract: The present invention discloses a boron-containing pharmaceutical composition useful in boron neutron capture therapy of hepatoma, which includes lipiodol, stibmicron boron powder, lecithin and unsaturated fatty acid. The lipiodol has a property of a high retention in hepatoma, the lecithin has a boron carrying capacity, and the unsaturated fatty acid has a function of rendering lecithin soluble in lipiodol.
