Investigations on the Formation of Urinary Coproporphyrin Isomers I-IV in 5-Aminolevulinic Acid Dehydratase Deficiency Porphyria, Acute Lead Intoxication and After Oral 5-Aminolevulinic Acid Loading

Tirnc evolution of spherical diffusion layer over dot electrodes was observed by Mach-Zehnder laser interferometer. The current response of those interdigitatcd dot electrodes was varied by the geometry of the electrode. The interferograms explained this in terms of the variation of the convective ion flux under the gravitational field.
