The present study was carried out to determine if Scutellaria balicalensis Georgi. extract (SBGE) exerts beneficial effect against the renal failure in rabbits. Rabbits were pretreated with SBGE orally for 7 days, followed by cisplatin injection (5 mg/kg, i.p.), cisplatin injection caused an increase in serum creatinine level, which was accompanied by a reduction in GFR. The fractional excretion of Na+, K+, glucose, and phosphate increased in cisplatin-treated animals, which was prevented by SBGE pretreatment. The uptake of p-aminohippurate, an organic anion, in renal cortical slices was inhibited by the administration of cisplatin, and the effect was prevented by SBGE. cisplatin injection increased lipid peroxidation, which was prevented by SBGE pretreatment. These results indicate that lipid peroxidation plays a critical role in cisplatin-induced acute renal failure. SBGE exerts the protective effect against acute renal failure induced by cisplatin, and its effect may be attributed to an antioxidant action.

Scutellaria baicalensis Georgi. (SBGE) is known to be antioxidant effect. In addition of the effects, we further investigated the SBGE on the antioxidant effect on a renal cortical slices cell and kidney protecting effects. The results were as follows. 1 When renal cortical slices separated from a rabbit's kidney were treated with 1mM tert-Butylhydroperoxide (t-BHP) in the presence of SBGE. SBGE significant prevented t-BHP induced increase in lactate dehydrogenase (LDH) release and lipid peroxidation. 2. When renal cortical slices separated from a rabbit's kidney were treated with oxidant $300{\mu}M$ cisplatin in the presence of SBGE. SBGE significant prevented cisplatin-induced increase in LDH release and lipid peroxidation. 3. Pretreatment with 0.1g/kg SBGE for seven day and treatment with 5 mg/kg cisplatin by the intraperitoneal injection The results were that the pretreatment group with SBGE showed a significant decrease in lipid peroxidation, increase in clearance rate of blood urea nitrogen (BUN) and creatinine in the kidney than the administering single agent group of cisplatin. and pretreatment group with SBGE showed intact microvillus of proximal tubule and no contraction of rumen, it was a similar result with normal group. With the results SBGE showed to be highly effective on antioxidant effect and cellular protection activity against cisplatin that was a toxic agent on a kidney. Therefore, SBGE is considered to have protective effective on a disordered kidney or kidney diseases such as nephritis or renal failure that cause tissue damages in a kidney.

Background: The objective was to study the effect of Scutellaria baicalensis Georgi ethanol extracts (SBGE) on immune and anti-oxidant function in U14 tumor-bearing mice. Materials and Methods: U14 tumor-bearing mice were randomly divided into eight groups: a control group, a cyclophosphamide (CTX) group, three dose groups of SBGEI (high, medium, low), and three dose groups of SBGEII (high, medium, low). After two weeks, the thymus and spleen weight indices of mice bearing U14 cervical cancer were calculated. Enzyme linked immunosorbent assays (ELISA) was used to determine the levels of serum IL-2, TNF-${\alpha}$, IL-8, and PCNA. MDA activity and SOD activity in plasma were measured with detection kits. Results: In the SBGE groups, thymus weight and spleen weight indices of U14 tumor-bearing mice were significantly higher than in the control group or CTX group (p<0.05). Compared to control group, the levels of serum IL-2 and TNF-${\alpha}$ in U14 tumor-bearing mice increased significantly, whereas the contents of serum IL-8 and PCNA decreased (p<0.05). The activity of SOD increased with the growing dose of SBGE, while the activity of MDA decreased significantly in the highe-rdose groups of SBGE. Conclusions: These findings suggested that SBGE, especially at high dose, 1000 mg/kg, showed significant immune and anti-oxidant effects infU14 tumor-bearing mice, which might be the mechanisms of SBGE inhibition of tumor growth.

Objective : This study was performed to determine if Scutellaria balicalensis Georgi extract (SbGE) prevents oxidant-induced membrane transport dysfunction in renal tubular cells. Methods : Membrane transport function was estimated by measuring $Na^+$-dependent inorganic phosphate transport in opossum kidney (OK) cells. $H_2O_2$ inhibited phosphate transport in a dose-dependent manner. Results : The inhibitory effect of $H_2O_2$ was significantly prevented SbGE over concentration range of 0.005-0.05%. $H_2O_2$ caused ATP depletion, which was prevented by SbGE. $H_2O_2$ induced the loss of mitochondrial function as evidenced by decreased MTT reduction and its effect was prevented by SbGE. The $H_2O_2$-induced inhibition of phosphate transport was not affected by a potent antioxidant DPPD, but the inhibition was prevented by an iron chelator deferoxamine, suggesting that $H_2O_2$ inhibits $Na^+$-dependent phosphate transport via an iron-dependent nonperoxidative mechanism in renal tubular cells. Conclusion : These data suggest that SbGE may exert the protective effect against oxidant-induced membrane transport dysfunction by a mechanism similar to iron chelators in renal epithelial cells. However, furher studies should be carried out to find the active ingredient(s) of SbGE that exerts the protective effect.
