Porphyrins of the I and in Series III Congenital Porphyrinuria

Abstract

As the result of a detailed chemical examination carried out post mortem upon a bovine suffering from congenital porphyrinuria¹, and my paper appearing in the Onderstepoort Journal of Veterinary Science (vol. 7, No. 2), I have been able to isolate porphyrins similar to those found by Fischer² and his collaborators in the human porphyrinuric Petry, but in addition have also obtained coproporphyrin, ester m.p. 243–44°, from the blood plasma and of m.p. 241° from the washed erythrocytes ; both uroporphyrin, ester m.p. 276–77°, and coproporphyrin, ester m.p. 244–45°, from the bone marrow ; uroporphyrin, ester m.p. 278°, from the spleen and uroporphyrin together with its copper complex, ester m.p. 313°, from the liver.
