[Origin and pathogenesis of polymeric dipyrrilmethenes].

By means of the silicagel thin layer chromatography and spectrophotometry the qualitative differences of the polymeric dipyrryl methenes in the bile and in the urine in normal and pathological conditions were demonstrated. The differences between the polymeric dipyrryl methenes of fresh hepatic bile and the polymeric dipyrryl methenes of the older hepatic and fresh duodenal bile were found. The same differences were found in the urine between the normal urinary polymeric dipyrryl methenes and the polymeric dipyrryl methenes in the hyperhemolytic state and in the bile duct obstruction. An entirely different quality of the polymeric dipyrryl methenes in the urine is to be admitted in the liver diseases.
