[Adjustment effect of Radix Astragalus and Radix Angelicae sinensis on TNF-alpha and bFGF on renal injury induced by ischemia reperfusion in rabbit].
OBJECTIVE
To study the mechanism of Astragalus membeanaceus and Angelica sinensis inrenal ischemia reperfusion injury of rabbits.


METHODS
Thirty-four heathy mature Japanese big-ear rabbits were randomized into control group, IR model group, Astragalus Membeanaceus + IR groupand Danggui + IR group. Renal ischemia lasted for 1 hour and then the renal reperfusion lasted for 48 hours. At the end, kidneys were observed with Electron Microscopy and the level of Cr in serum and the level of TNF-alpha and bFGF in kidneys were measured.


RESULTS
The changes of kidneys in IR model group were significant, but they were slight in Astragalus Membeanaceus + IR group and Danggui + IR group. The level of Cr in serum and the level of TNF-alpha in kidneys of IR model group were higher and yet the level of bFGF decreased obviously. The level of Cr and TNF-alpha in Astragalus Membeanaceus + IR group and Danggui + IR group was lower than that in IR model group and the level of bFGF was higher than that in IR model group.


CONCLUSIONS
The mechanism of Astragalus Membeanaceus and Danggui in remedying renal IR injury may be relative to their regulation of TNF-alpha, bFGF and other cytokines.
