Occurrence of persistent elevated levels of serum glutamic oxaloacetic transiminase as a result of enzyme-immunoglobulin complex formation --with a report of two cases--.

Two cases of macro-molecular GOT (glutamic oxaloacetic transaminase) were encountered recently. Both were middle-aged women, showing no abnormality in laboratory test results including those for GPT (glutamic pyruvic transaminase), except that abnormality high values (ca. 200 Karmen unit) were obtained for GOT. Clinical examinations and tests on the liver, heart, skeletal muscle and other organs were negative. By column chromatography, immunoelectrophoresis and other procedures, this macro-molecular GOT was shown to be an anzyme immunoglobulin complex with a molecular weight of about 250,000 formed by the binding of the GOT of the cytoplasmic fraction to Ig-G-Kappa.
