OBJECTIVE: To study the links between chronic pyelonephritis (CPN) and immune function, and the action mechanism of Yishenkang granule on CPN. METHODS: A total of 120 CPN cases were randomly assigned to Yishenkang granule group, Sanjing tablet group and western medicine group, which were compared with healthy control group. The levels of the peripheral blood T lymphocyte subsets, serum immunoglobulin, complement, secretory IgA in urine and the cell factor IL-2 in CPN cases before and after treatment were detected by monoclonal antibody method, agar diffusion method, radioimmunoassay, radioimmune balancing method and compared with those in healthy control group. RESULTS: In CPN cases compared with healthy control group, the levels of serum immunoglobulin, complement, secretory IgA in urine were significantly lower while the level of cell factor IL-2 were significnatly higher (P
