Estudios acerca de las enzimas del hemo en bazo de porfiria congenita eritropoyetica y de los efectos de las porfirinas sobre la actividad enzimatica: porfobilinogenasa

To establish whether or not porphyrins have any photodynamic and/or non-photodynamic action on the spleen PBGase further experiments are needed assaying: 1) different types of porphyrins, 2) higher concentrations, 3) different irradiation energies, 4) different temperatures and 5) different exposure times
