Studies on Serological Reactions in Infectious Hepatitis Part 1. Studies on Auto-Liver-Antibody by Means of Colloidion Agglutination Reaction

Studying the significance of serological diagnosis of auto-liver-antibody by means of collodion agglutination reaction, and also observing the production of the antibody following a few experimental liver impairments, the following results were obtained. 1. Positive titers of agglutination was determined as 128 times since the majority of the collodion agglutination reactions in the healthy individuals as well as in the cases of extrahepatic diseases, demonstrated below 128 times. 2. The positive titers of agglutination were noted in 73.9% on investigating the auto-liver-antibody of infectious hepatitis by means of the collodion agglutination reaction. 3. Observing the alteration of the auto-liver-antibody of infectious hepatitis by means of the collodion agglutination reaction and complement fixation reaction, it was noted that the collodion agglutination was more sensitive and that there were relatively high positive titers of the antibody in the acute stages (the second and third week) as well as in the chronic stages. 4. In the mutual relations between the quantities of the auto-liver-antibody detected by the agglutination reaction, the various clinical pictures and the laboratory data of infectious hepatitis, the reactive positive titer of agglutination have increased in proportion to serum colloid liver function tests, serum bilirubin (over 1 to 2 mg. %), positive urine urobilinogen reaction, and to hepato-splenomegalia. No evident correlation was noted between the reactive positive titers of agglutinations and the hemograms of infectious hepatitis, but in the group of the positive reaction fairy numbers of the cases with lymphocytosis and monocytosis were seen, compared with the group of negative ones. 5. Detecting the auto-liver-antibody by means of the collodion agglutination reaction have reflected the clinical pictures fairly well and would be a effective means for clarify the pathophysiology of hepatic diseases. 6. For the purpose of the investigation regarding the production of the auto-liver-antibody in case of aseptic liver impairment, experiments were performed such as aseptic squeezing, cauterization and ligation of the common bile duct. In these experiments, a production of the auto-liver-antibody was confirmed, in relatively early stages, by means of the collodion agglutination reaction
