尿路感染症に関する免疫学的研究

Abstract

A study was made on relation between serum immunoglobulin, serum complement and white blood cell, red blood cell in urine in normal subjects, upper urinary tracts infection and lower urinary tract infection. Serum complement and immunoglobulins were determined in all cases. In upper urinary tract infection, the value of serum complement was normal, that of serum IgA and IgG were low and that of serum IgM was high. In lower urinary tract infection, the value of serum complement and IgM were normal and that of serum IgA and IgG were high. In upper urinary tract infection, the number of white blood cell in urine significantly related with the value of serum complement, IgA and IgM but not with serum IgG. In lower urinary tract infection, the number of white blood cell in urine did not relate with value of serum complement, IgA, IgM and IgG. In urinary tract infection, the number of red blood cell in urine did not relate with the value of immunoglobulin IgA, IgM, IgG and complement.
