Abstract
Urinary and skin porphyrins were determined with thin layer chromatography and fluorescent scanning analysis in 6 hexachlorobenzene-induced porphyric rats. In both urine and skin, uroporphyrin predominated followed by heptacarboxylic porphyrin and/or coproporphyrin. After UV-A irradiation, there were neither significant changes in the skin porphyrin level nor direct correlation between skin porphyrin levels and intensities of the UV light irradiated. However, there was an intimate correlation between the fluctuation of the skin levels of the uroporphyrin and of the heptacarboxylic porphyrin.
