  • Patent number: 5455022
    Abstract: A method for performing boron neutron capture therapy for the treatment of tumors is disclosed. The method includes administering to a patient an iodinated sulfidohydroborane, a boron-10-containing compound. The site of the tumor is localized by visualizing the increased concentration of the iodine labelled compound at the tumor. The targeted tumor is then irradiated with a beam of neutrons having an energy distribution effective for neutron capture. Destruction of the tumor occurs due to high LET particle irradiation of the tissue secondary to the incident neutrons being captured by the boron-10 nuclei. Iodinated sulfidohydroboranes are disclosed which are especially suitable for the method of the invention. In a preferred embodiment, a compound having the formula Na.sub.4 B.sub.12 I.sub.11 SSB.sub.12 I.sub.11, or another pharmaceutically acceptable salt of the compound, may be administered to a cancer patient for boron neutron capture therapy.

  • Patent number: H1479
    Abstract: An apparatus which determines concentrations of each of three components that are intermixed in a homogeneous solution. Each component is detectable by at least one characteristic and more than one characteristic is associated with more than one component. First, characteristics that are quantitatively detectable in relation to the concentrations of the components are identified. A mathematical relationship is then developed between the components and the detectable characteristics using the detectable characteristics as independent variables. A sample of the solution is then analyzed to obtain quantitative data of each of the characteristics. The obtained quantitative data is then employed in the mathematical relationship to obtain the concentration of each of the components.
