1) In order to study the correlation between the erythrocyte sedimentation rate and each fraction of the plasma protein in pulmonary tuberculosis cases, the samples in a total of 153 of plasma protein were obtained from 57 patients and examined by the electrophoretic method, and the correlation between the erythrocyte sedimentation rate and concentration of each fraction in plasma protein is statistical-ly discussed.
2) There is a significant negative correlation between albumin and the com-mon logarithmic value of the erythrocyte sedimentation rate, a significant positive correlation between total globulin, fibrinogen, α-globulin, β-globulin and γ-globulin and the common logarithmic value of the erythrocyte sedimentation rate. There was no correlation between the concentration of total protein and the common logarithmic value of the erythrocyte sedimentation rate.
3) The correlation between albumin and total globulin and fibrinogen and the erythrocyte sedimentation rate is high. In comparison between albumin and total globulin, total globulin shows the strongest correlation and fibrinogen in globulin fractions shows also the strongest, while there is no orders in degrees with the others.
4) After having calculated the reggression-lines between the concentration of the fractions of plasma protein and the common logarithmic value of the erythrocyte sedimentation rates, I found that there were very close relation when the sedimenta-tion rates are low. But when the rates are high over certain limits the relations become less close.
Therefore, when the sedimentation rate is markedly accelerated the role of the unstability of plasma protein is no more overwhelming and the effects of various other factors must be considered as well. Furthermore the influence of the propor-tions of each fraction of protein can not be ignored.
I am indebted to Prof. Jiro Ishida and Assistant Prof. Jiro Gorni, the depart-tuent of internal medicine, for their many valuable advices. Thanks arc also due to my colleague M. Honda for his kind assistance and to Instructor S. Sato, the chief of the laboratory of clinical statistics, for criticisms on statistical procedures.
