This study was undertaken to determine whether Scutellaria baicalensis Georgi (SbG) extract exerts the protective effect against -induced alterations in membrane transport function in rabbit renal cortical slices. The slices were treated with 0.1 mM

caused an inhibition in PAH uptake by renal cortical slices. Such an effect was accompanied by depressed
-ATPase activity and ATP depletion. SbG prevented
-induced inhibition of PAH uptake in a dose-dependent manner at the concentration ranges of 0.01-0.1%.
-induced inhibition of
-ATPase activity and ATP depletion were significantly prevented by 0.05% SbG. These results suggest that SbG prevents
-induced alterations in membrane transport function in rabbit renal cortical slices. Such protective effects of SbG may be attributed to inhibition of peroxidation of membrane lipid.
