Autoradiographic Observations on Injected S³⁵‐Thiocyanate and C¹⁴‐Cyanide in Mice

Abstract

Abstract The labelled compounds were injected into mice and sections of the whole animals were studied by an autoradiographic technique. The two compounds studied gave an almost identical autoradiographic distribution pattern. This was attributed to the fact that the activity after injection of KC 14 N was present mainly as thiocyanate. A very high activity was present in the stomach as early as 5 min after injection and it remained higher there than in any other organ during the 24‐hours observation period. High activities were also found in the submaxillary salivary gland, the thyroid gland, the walls of the large vessels and the blood.
