    Abstract

    To study the relationship between serum vascular endothelial growth factor (VEGF) and proteinuria in adriamycin-induced nephrotic
    rats, a rat model of adriamycin-induced nephrotitis was developed by injection of adriamycin into a tail vein in a rat. At
    different time points, 24-h urinary protein excretion was measured by using Coomassie brilliant blue method and the serum
    VEGF levels detected by using ELISA assay. The interventional effect of VEGF on this model was observed. The results showed
    that: (1) The adriamycin-induced nephrotic syndrome rat model was developed successfully; (2) Serum VEGF levels and proteinuria
    were significantly increased at 7th day after intravenous injection of adriamycin. There was a positive correlation between
    serum VEGF levels and 24-h urinary protein excretion (r=0. 67,P<0. 05). (3) The 24-h urinary protein excretion was significantly increased in the rats receiving administration of VEGF (P<0. 05). It was concluded that VEGF might play an important role in the pathogenesis of proteinuria in adriamycin-induced
    nephrotic rats.
