【Abstract】 A modified immunofluorescence method and mouse rosetteforming cell （m-RFC） assay were used to measure peripheral B cells in human controls of different age groups. The mean values measured by these methods were 10.72±1.83% and 9.19±2.44% respectively.In order to find out whether the values of B and T cells were related to certain diseases, we measured B and T cells of the peripheral blood of acute glomerulonephritis, systemic lupus erythromatosis and thyroid disease patients, with an emphasis on the glomerulonepnritis patients in whom B and T cells, total complement activity and C₃ were compared before and after treatment. It was found that the mean value of B cells before treatment was very significantly increased （P<0.001）, accompanied with significant reduction of total complement and C₃ （P<0.01）. After treatment, both values reduced to normal. The value of T cell did not show any significant change. The authors suggested that the measurement of above mentioned values is very important for the understanding of the pathogenesis, treatment and prognosis of acute glomerulonephritis and other autoimmune diseases.更多还原
