[Studies on enzymes (transaminases, OCT) and Au Antigen in infectious hepatitis]

The Authors, after reviewing the problem of Au antigen, recalling the numerous theories thereabout, making reference to the sure datum that the blood containing Au antigen is infecting, and that the Au antigen is synthesized in liver, report the data of laboratory remarked in some epidemic episodes of infectious hepatitis. Besides the Au antigen, 2 enzymes were compared (transaminase and OCT), as liver is particulary rich in enzymes in comparison to other organs: the glutamico-oxalacetic and glutamico-piruvic transaminase in cytoplasmic seat and ornithine-carbamyl-transferase in mitocondrial seat; such enzymes shoud also have a specific meaning and indicate precociousness. From the study of the different episodes, and particularly from the 82 cases resulting positive with one, two or three parameters, they draw the conclusions that the research of the three parameters proved useful from the epidemiologic standpoint, as well as for prevention and timely diagnosis according to the conception of investigations in theme of public health.
