SUMMARY Polymorphic cells whose granules give a positive chromaffin reaction have been identified in the liver capsule and gut of the ox, cow and sheep. These cells give a positive argentaffin and Schmorl's reaction in dichromate-fixed material, and fail to couple with alkaline diazonium compounds. These reactions are consistent with the presence of a catechol, and from the work of Bertler, Falck, Hillarp, Rosengren & Torp (1959) it would appear that they contain dopamine. These chromaffin, dopamine-containing cells are, however, not a special type of cell but are tissue mast cells. Nuclear fast red (Herzberg) is not, as suggested by Falck, Hillarp & Torp (1959a, b), a specific stain for dopamine, but, when prepared with aluminium sulphate, it is specific for sulphated mucopolysaccharides.

Mouse Thyroid

A method for the autoradiographic localization of water-soluble diffusible ions has been developed and applied to the localization of iodide125 in the mouse thyroid gland. Frozen-dried thyroids of hypophysectomized mice containing radioiodine125 as inorganic iodide125 were embedded in paraffin. Sections were spread on mercury and mounted on autoradiographic film. After exposure the mounted section was permanently fastened directly over its latent image and tissue constituents were fixed by dipping in 80% aqueous methanol. The preparation was air dried and then deparaffinized with petroleum either. After development and fixation, slides were stained with Nuclear Fast Red. In certain cases radioiodide could be localized primarily in the follicular epithelium. Control studies demonstrated that the autoradiographic image was not an artifact resulting from chemical induction or suppression of selected areas of latent image. A comparison of autoradiographs prepared from frozen sections and those prepared by freeze-drying showed similar localization of the radioisotope and indicated that there was no displacement of the radioiodide during paraffin embedding.

AbstractA novel fluorometric method for the determination of adenine was proposed, based on the fluorescence quenching of a nuclear fast red-silver complex as a small molecule optical probe in the presence of adenine. The characteristic spectra of absorption, resonance Rayleigh scattering (RRS) and the fluorescence of the system were analysed. Adenine, Ag
