ABSTRACT

Objective To investigate the therapeutic effects of rhein on experimental diabetic nephropathy in rats. Methods Rat model of diabetic mellitus was established by interperitoneal injection of streptozotocin (50 mg/kg) . Renal damages and changes of endothelin (ET) in urine and renal tissues were observed at 12 weeks after the induction of diabetic mellitus and after treatment with rhein (70 mg/kg). Results Compared with the normal rats, at 12 weeks after hyperglycemia, diabetic rats had decreased renal weight/body weight(RW/BW), significantly increased mean glomerular plane area (MGPA), mean glomerular volume (MGV), creatinine clearance rate (Ccr), blood urea nitrogen (BUN), and 24 hour urinary protein excretion (UPE) ( P
