Thermostability of the erythrocytes of mice exposed to the action of a magnetic field.

The authors investigated the thermostability of the erythrocytes os strain CBA mice exposed to the action of a magnetic field formed by the poles of a rotating permanent magnet of 20 mT (200 GAUSS) induction. The erythrocytes of animals which spent 17 weeks in the magnetic field were significantly less heat resistance than those of the control animals. The effect on animals kept in the magnetic field during embryoyenesis and infancy and then left 3 months outside it was even more pronounced.

Effect of prolonged exposure to a magnetic field on the haematopoietic stem cell.

The authors studied the effect of prolonged exposure (3, 4 and 5 months) to the action of a magnetic field of 180-200 gauss formed by the poles of a rotating permanent magnet on the haematopoietic stem cells of mouse bone marrow donors. The effect of the field was evaluated from the ability of the donors' bone marrow cells to form haematopoietic colonies in the spleen of lethally irradiated mice. It was found that the number of stem cells was not reduced by the action of the above magnetic field and that proliferative capacity was likewide unimpaired.

[Certain practically important questions on the intra-osseous hemangioma of the jaw].

With special regard to the viewpoint of the general stomatologist, the authors deal with the problems related to the intraosseous haemangioma of the jaw and try to give a clearly arranged survey of the criteria of this extensive complex of questions, using schematic tables. They point above all to the risks of inconsiderate management and indicate the diagnostic and therapeutic possibilities which are available only in a special clinic. Finally, the authors present two personal cases, describing in detail (with reference to the preceding representations) the course of the disease in a 17-year-old female patient.
