Four phthalocyanines (iron tetracarboxylphthalocyanine, copper tetracarboxylphthalocyanine, manganese tetracarboxylphthalocyanine, cobalt tetracarboxylphthalocyanine) were used as dual functional mimic enzymes of superoxide dismutase (SOD) and catalase (CAT). The first function, eliminating O2－, was proved by using riboflavine-methionine photoreduction method in the concentration range of 10－5 to 10－6 mol/L. The second function, clearing out H2O2, was demonstrated by means of spectrophotometry with the decomposing percentage being increased with the increase of the concentration of the imitating compounds. Measurements of metal phthalocyanines, SOD and CAT by the liver homogenate technique of mice showed that they had obvious action of decreasing the lipid peroxidation.

A male patient, with diagnose of Madelung disease, was admitted in September 2009. He has been a heavy drinker for decades before onset of the disease. This patient was characterized by the large amount of symmetrical deposits of adipose tissue in the subcutaneous layer around neck, and without obesity on other sites. The excessive adipose tissue was surgically removed by three steps. Appearance almost returned to normal. No recurrence happened after 8 years of follow-up.
