Ureteral obstruction can be causes of renal dysfunction and renal injury at late period of kidney pathology. The purpose of this study was to determine the protective effects of Oryeongsan (ORS), Geumgwe-sinkihwan (GSH), and Jwagwieum (JGE) in rats with unilateral ureteral obstruction (UUO). The animal models were divided into five groups randomly at the age of 5 weeks; Control group: SD male rats (n=10), UUO group: SD male rats with UUO surgery (n=10), ORS group: SD male rats with UUO surgery + ORS 200 mg/kg/day (n=10), GSH group: SD male rats with UUO surgery + GSH 200 mg/kg/day (n=10), JGE group: SD male rats with UUO surgery + JGE 200 mg/kg/day (n=10). Treatment with ORS, GSH, and JGE significantly ameliorate creatinine clearance(Ccr). The present results also showed that ORS, GSH, and JGE improved the morphological aspects of renal tissues. These prescriptions also reduced the expression levels of cytokines such as TNF-α, IL-1β, and IL-6. In Kidney, UUO increased the expression levels of inflamasome markers such as NLRP3, ASC, and Caspase-1. However, ORS, GSH, and JGE suppressed these levele. Treatment with these prescriptions reduced kidney inflammation markers such as Neutrophil Gelatinase Associated Lipocalin (NGAL) and kidney injury molecule -1 (KIM-1). Therefore, these findings suggest that ORS, GSH, and JGE has a protective effect on renal injury by alleviating renal inflammation and improving renal function in rats with UUO.

To evaluate the effect of the saponin of heat-processed ginseng (Sun ginseng, SG), we investigated the protective effect of SG total saponin fraction against adenine-induced chronic renal failure in rats. SG saponin significantly decreased the levels of urea nitrogen and creatinine in the serum, but increased the urinary excretion of urea nitrogen and creatinine, indicating an improvement of renal function. SG saponin also inhibited adenine-induced kidney hypertrophy and edema. SG saponin reduced serum glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, and lactate dehydrogenase activities increased by adenine. Based on these findings, the ameliorating effect of SG on chronic renal failure may result from its saponin.

In this study, the antioxidative effect and protective potential against oxidative damage of extract and fractions from broccoli were investigated under in vitro and cellular system. The methanol (MeOH) extracts of broccoli flowers and sprouts were partitioned as dichloromethane, n-butanol (BuOH) and aqueous fractions. The comparison of antioxidative effect of broccoli flowers and sprouts showed that broccoli sprouts exerted the more effective protective activity from 2,2'-azobis (2-aminopropane) dihydrochloride (AAPH)-induced oxidative stress in LLC-$PK_1$ porcine renal epithelial cell. In addition, the extract and fractions from broccoli sprouts showed strong scavenging effect of 1,1-diphenyl-2-picrylhydrazyl radical and the BuOH fraction exerted the strongest activity. Therefore, the BuOH fraction was evaluated as the most active fraction with strong radical scavenging activity among the fractions of broccoli flowers and sprouts. The present study suggests the antioxidative potential against free radical-induced oxidative damage of flowers and sprouts of broccoli. In addition, the BuOH fraction of broccoli is considered as the active fraction with antioxidative effect.

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.

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.

The effect of orally administered sun ginseng (SG), which is a ginseng processed by steaming, was examined in adenine-induced chronic renal failure rat. SG significantly decreased both blood urea nitrogen and serum creatinine levels, indicating an improvement of renal function. Also, SG significantly increased the urinary excretion of both urea and creatinine. Furthermore it lowered the blood pressure, and inhibited adenine-induced kidney hypertrophy and edema. Based on these findings, SG may ameliorate chronic renal failures.

Objective : This study was undertaken to determine whether Cordyceps sinensis Sacc. (CSS) extract exerts the protective effect against oxidant-induced alterations in membrane transport function in renal tubules. Methods : Membrane transport fucntion was estimated by examining alterations in p-aminohippurate (PAH) uptake in rabbit renal cortical slices. For induction oxidative stress, slices were treated with an organic peroxide cumene hydroperoxide for 60 min at $37^{\circ}C$. Cumene hydroperoxide inhibited PAH uptake in a time dependent manner. Results : CSS at 0.5-5% concentrations prevented cumene hydroperoxide-induced inhibition of PAH uptake. CSS at 1% also attenuated LDH release and lipid peroxidation induced by cumene hydroperoxide. When slices were treated with 0.2 mM mercury chloride, PAH uptake was inhibited and lipid peroxidation was increased. These changes by mercury were significantly prevented by CSS. Conclusion : These results suggest that CSS prevents oxidant-induced alterations in membrane transport function in rabbit renal cortical slices. Such protective effect of CSS may be attributed to inhibition of peroxidation of membrane lipid.

Objectives : The present study was carried out to determine if Glycyrrhizae Radix extract exerts beneficial effect against the ischemia-induced acute renal failure in rabbits. Glycyrrhizae Radix was known to reinforce the function of the spleen and replenish Qi, remove heat and counteract toxicity, dispel phlegm and relieve cough, alleviate spasmodic pain, and to moderate drug actions. It's indications are weakness of the spleen and the stomach marked by lassitude and weakness; cardiac palpitation and shortness of breath; cough with much phlegm: spasmodic pain in the epigastrium, abdomen and limbs: carbuncles and sores. It is often used for reducing the toxic or drastic actions of other drugs. Methods : Antioxidative effect of 3% concentration of Glycyrrhizae Radix extract was measured. Rabbits were treated with Glycyrrhizae Radix extract via i.v., followed by renal ischemia/reperfusion, and the changes of urine volume, serum creatinine levels, glomerular filtration rate(GFR), fractional Na+ excretion$(FE\;Na^+)\;and\;K^+\;excretion(FE\;K^+)$ in ischemia/reperfusion induced acute renal failure were measured. Results : Renal ischemia/reperfusion caused increase of serum creatinine level, which was accompanied by a reduction in glomerular filtration rate(GFR). The fractional excretion of $Na^+\;and\;K^+$ increased in ischemia-induced animals, which was partially prevented by Glycyrrhizae Radix extract treatment. Conclusions : These results indicate that lipid peroxidation plays a critical role in ischemia-induced acute renal failure. Glycyrrhizae Radix extract exerts the protective effect against acute renal failure induced by renal ischemia/reperfusion, and its effect may be attributed to an antioxidant action.
