Uroporphyrinogen decarboxylase deficiency in experimental chronic hepatic porphyria.Hoppe Seylers Z Physiol Chem. 1980 Aug; 361(8):1217-22.HS
During hexachlorobenzene feeding of rats the following biochemical signs of a chronic hepatic porphyria developed: porphyrinuria with increase of uro- and hexacarboxyporphyrin, hepatic prophyrin accumulation of uro- and heptacarboxyporphyrin and a diminished activity of uroporphyrinogen decarboxylase in the liver, but nut in the red cells. During the 5.3 days of the intoxication the behaviour of metabolite constellation and enzyme activities was inverse. Hexachlorobenzene porphyria in rats is a pathobiochemical model of chronic hepatic prophyria, which in man becomes clinically manifest as porphyria cutanea tarda.
