Abstract
All the teeth of a man suffering from porphyria congenita had a deep brown colour and a red fluorescence under filtered UV-light. An unerupted mesiodens was surgically removed, powdered and extracted for porphyrins, and the extract examined by fluorescent light and paper partition chromatography after purification on columns of talc. The amount of porphyrins was determined by a spectral absorption method (standard was haematoporphyrin) within 92μg per g dried tooth tissue. Chromatography in lutidine-water revealed a Rf-value like uroporphyrin I for nearly 3 4 of the substance. The rest was not identified.
