Objective: To observe the effect of Astragalus and Angelica on acute renal injury.
Methods: Using the ischemia/reperfusion model established by blocking blood flow through clamping of bilateral renal artery for 45 min, the changes of glomerular filtration rate (GFR), renal plasma flow (RPF), fractional excretion of sodium (FENa), urinary volume (UV) and mean arterial pressure (MAP) as well as the morphological change of kidney before and after ischemia/reperfusion were observed.
Results: Astragalus and Angelica could promote recovery of RPF and GFR after ischemia/reperfusion, prevent the oliguria or shorten the oliguria period, reduce the increment of FENa and improve the histomorphological injury of kidney.
Conclusion: Astragalus and Angelica have certain effect in protecting kidney from acute renal injury.
