RESUMO
Objective To explore change and significance of serum and urinary transforming growth factor-? 1(TGF-? 1)in the patients with primary chronic glomerulonephropathy (PCG). Methods 65 patients with PCG were divided into four groups according to the degree of renal function damage: normal renal function,renal compensatory,renal decompensatory and renal function failure groups. Levels of serum and urinary TGF-? 1 were determined with ELISA, and the levels of urinary protein and renal function were examined as well. Results Levels of serum and urinary TGF-? 1 in patients with PCG were singificantly higher than those in control, and the levels of serum and urinary TGF-? 1 among four groups were significantly different. The TGF-? 1 level of urinary was associated with the degree of renal function damage(r=0 28,P
