Different neoplastic response of mice and rats to infection by murine sarcoma virus (moloney).
Establishment of a virus-persistent cell line and deviation of malig- nant cell clones from rat osteosarcoma induced by a murine sarcoma virus (moloney).
Attempts to induce tubular deformations and subsequent mixed tumours from organotypic cultures of mouse renal mesenchyma.
Magnetic and X-Ray Diffraction Studies on Dextran Iron-Oxide Magnetic Fluid
Two types of dextran iron-oxide complexes (ATDM and CMDM), magnetic fluid applicable to the contrast agent of magnetic resonance imaging of living body, have been synthesized without surfactant. We have measured temperature dependances of magnetization and X-ray diffraction of ATDM, CMDM and also magnetite fine-particles as a reference substance in atmospheres of air and helium up to 840°C. The results are discussed in view of the reaction of magnetite core with the surrounding gas and products formed by thermal decomposition of the dextran molecules which is directly bonded to magnetite core of the complexes
