Serum protein analysis of 40 cases on pulmonary tuberculosis, by paper electro-phoresis and non-specific serum coloid reactions, such as cadmium, Gros, Takata and Weltmann reaction, were carried out.
The results obtained were as follows :
1) Increase in percentage of α-α2-and γ-globulin to total protein and decrease of albumin were observed in chronic pulmonary tuberculosis. These changes, except of β-globulin, were proportional to the stage of the disease.
2) Much increase of γ-globulin ware absened in far advanced pulmonary tuberculosis, but a few in mininal and mederately advanced.
3) Increase of α-globulin occurred as the disease tends to exudative type.
4) The changes of fraction of serum protein were compared with changes of non-specific serum coloid reaction (cadmium, Gros, Takata and Weltmann Reation); and the positivity rate of these reactions were related proportionaly to the percentage of serum albumin and γ-globulin mainly.
