RESUMO

Synthesis of radioactively labelled 2,4-diamino-5-[3,5,-dimethoxy-4-(2-methoxyethoxy)]-benzylpyrimidine (tetroxoprim) as needed for pharmacokinetic studies, is described. Commercial [14C]-guanidine hydrochloride was used as radioactive label.

RESUMO

The concept of the integral dose, being correlated with the system of immunity, has got an increased bearing on radiation therapy. Experimental determination of integral doses in a tissue-equivalent body-phantom by means of ferrosulfate dosimetry and potentiometric analysis is described. The results are discussed and compared considering X and Y irradiation techniques and different units for irradiation.

RESUMO

A method for the electrophoresis of inorganic radioactive cations on cellulose acetate (Cellogel) is described. The advantages of this technique are illustrated by numerous examples. Separations of the rare earth metals, the alkaline earths and fission products are mentioned particularly.

RESUMO

Previous work on th electrophoretic separation of rare earth mixtures in α-hydroxyisobutyric acid was continued using cellogel strips and radioactive tracers. The purity and sequence were determined by γ-spectrometric analysis and the decay of the various activities. The detection of rare earths by direct activation of the electropherogram is demonstrated. Mixtures containing all the lanthanoides are clearly separated.
