The present stuby was carried out to determine if Radix Glycyrrhizae extract exerts beneficial effect against the ischemia-induced acute renal failure in rabbits. Radix Glycyrrhizae 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. Rabbits were treated with Radix Glycyrrhizae extract via i.v., followed by renal ischemia/reperfusion. Fractional excretion of glucose and phosphate, lipid peroxidation and light microscopy were done to evaluate the beneficial effect of Radix Glycyrrhizae extract on ischemia/reperfusion induced acute renal failure. Renal ischemia/reperfusion caused increase of fractional excretion of glucose and phosphate increased in ischemia-induced animals, which was partially prevented by Radix Glycyrrhizae extract treatment. Ischemia/reperfusion increased lipid peroxidation, which was prevented by Radix Glycyrrhizae extract administration. And the beneficial effect of Radix Glycyrrhizae extract on ischemia/reperfusion induced kidney injury was shown through the light micrographic observation. These results indicate that lipid peroxidation plays a critical role in ischemia-induced acute renal failure. Radix Glycyrrhizae extract exerts the protective effect against acute renal failure induced by renal ischemia/reperfusion.

Objectives : This study was performed to determine if Orostachys japonicus A. Berger aquacupuncture (OjB) provides the protective effect against the loss of celi viability and DNA damage induced by oxidant in renal proximal tubular cells. Methods : The cell viability was evaluated by a MTT reduction assay and DNA damage was estimated by measuring double stranded DNA breaks in opossum kidney (OK) cells, an established proximal tubular cell line. Lipid peroxidation was determined by measuring malondialdehyde (MDA), a product of lipid peroxidation. Results : $H_2O_2$ increased the loss of cell viability in a time-dependent manner, which were prevented by 0.1% OjB. The protective effect of OjB was dose-dependent over concentration range of 0.05-0.5%. $H_2O_2$ caused ATP depletion and DNA damage, which were prevented by OjB and the hydrogen peroxide scavenger catalase. The loss of cell viability by $H_2O_2$ was not affected by the antioxidant DPPD, but lipid peroxidation by the oxidant was completely inhibited by DPPD. Conclusions : These data suggest that $H_2O_2$-induced death results from a lipid peroxidation-independent mechanism and the protective effect of OjB is not associated with its antioxidant activity.

Liver and kidney are specific organs which play an active role in biotransformation and detoxification mechanisms. Ant adverse effect of chemicals or heavy metal can cause the delay or fade in these mechanisms. Present study was designed to find out the protective effect of Panax ginseng extract on renal functions altered by mercuric chloride (heavy metal) in albino rat. Fifty albino rats were divided into 10 groups. Five groups for acute study and five groups for sud-acute study viz. control group (Tween 20 and distilled water), mercuric chloride treated group (0.926 mg/kg body wt. for acute and 0.044 mg/kg body wt. for sub-acute group after calculated $LD_{50}$ (9.26 mg/kg body wt.) by probit analysis (Finney, 1971), Panax ginseng extract treated group (10 mg/kg body wt. for acute and sub-acute sets), mercuric chloride treated followed by Panax ginseng extract and Panax ginseng extract followed by mercuric chloride group. All doses were given orally by gavage tube. The result revealed that the serum urea and creatinine significantly increased in mercuric chloride treated group, while significantly decreased (p<0.01) in Panax ginseng extract group after acute and sub-acute treatment. The biochemical estimation is also confirmed by nephropathological aspect. However, the Panax ginseng extract treated followed by mercuric chloride group is more prominent than the mercuric chloride treated followed by Panax ginseng extract group. It can be concluded that Panax ginseng extract had a protective nature on renal functions against mercuric chloride toxicity in albino rats.

Overdoses of acetaminophen cause hepato-renal oxidative stress. The present study was undertaken to investigate the protective effect of a 43 kDa protein isolated from the herb Cajanus indicus, against acetaminophen-induced hepatic and renal toxicity. Male albino mice were treated with the protein for 4 days (intraperitoneally, 2 mg/kg body wt) prior or post to oral administration of acetaminophen (300 mg/kg body wt) for 2 days. Levels of different marker enzymes (namely, glutamate pyruvate transaminase and alkaline phosphatase), creatinine and blood urea nitrogen were measured in the experimental sera. Intracellular reactive oxygen species production and total antioxidant activity were also determined from acetaminophen and protein treated hepatocytes. Indices of different antioxidant enzymes (namely, superoxide dismutase, catalase, glutathione-S-transferase) as well as lipid peroxidation end-products and glutathione were determined in both liver and kidney homogenates. In addition, Cytochrome P450 activity was also measured from liver microsomes. Finally, histopathological studies were performed from liver sections of control, acetaminophen-treated and protein pre- and post-treated (along with acetaminophen) mice. Administration of acetaminophen increased all the serum markers and creatinine levels in mice sera along with the enhancement of hepatic and renal lipid peroxidation. Besides, application of acetaminophen to hepatocytes increased reactive oxygen species production and reduced the total antioxidant activity of the treated hepatocytes. It also reduced the levels of antioxidant enzymes and cellular reserves of glutathione in liver and kidney. In addition, acetaminophen enhanced the cytochrome P450 activity of liver microsomes. Treatment with the protein significantly reversed these changes to almost normal. Apart from these, histopathological changes also revealed the protective nature of the protein against acetaminophen induced necrotic damage of the liver tissues. Results suggest that the protein protects hepatic and renal tissues against oxidative damages and could be used as an effective protector against acetaminophen induced hepato-nephrotoxicity.

Background: Ginsenoside Rd (GSRd), a main component of the root of Panax ginseng, exhibits anti-inflammation functions and decreases infarct size in many injuries and ischemia diseases such as focal cerebral ischemia. M1 Macrophages are regarded as one of the key inflammatory cells having functions for disease progression. Methods: To investigate the effect of GSRd on renal ischemia/reperfusion injury (IRI) and macrophage functional status, and their regulatory role on mouse polarized macrophages in vitro, GSRd (10-100 mg/kg) and vehicle were applied to mice 30 min before renal IRI modeling. Renal functions were reflected by blood serum creatinine and blood urea nitrogen level and histopathological examination. M1 polarized macrophages infiltration was identified by flow cytometry analysis and immunofluorescence staining with $CD11b^+$, $iNOS^+$/interleukin-12/tumor necrosis factor-${\alpha}$ labeling. For the in vitro study, GSRd ($10-100{\mu}g/mL$) and vehicle were added in the culture medium of M1 macrophages to assess their regulatory function on polarization phenotype. Results: In vivo data showed a protective role of GSRd at 50 mg/kg on Day 3. Serum level of serum creatinine and blood urea nitrogen significantly dropped compared with other groups. Reduced renal tissue damage and M1 macrophage infiltration showed on hematoxylin-eosin staining and flow cytometry and immunofluorescence staining confirmed this improvement. With GSRd administration, in vitro cultured M1 macrophages secreted less inflammatory cytokines such as interleukin-12 and tumor necrosis factor-${\alpha}$. Furthermore, macrophage polarization-related pancake-like morphology gradually changed along with increasing concentration of GSRd in the medium. Conclusion: These findings demonstrate that GSRd possess a protective function against renal ischemia/reperfusion injury via downregulating M1 macrophage polarization.

Objective : The present study was carried out to determine if Semen Plantaginis Herbal-Acupuncture exerts beneficial effect against the cisplatin-induced acute renal failure in rabbits. Method : Semen Plantaginis was selected in the basis of invigorating kidney-QI which can eliminate pathogens. The oxidative stability determined by the Rancimat technique showed higher antioxidative index when compared with control. Rabbits were treated with Semen Plantaginis Herbal-Acupuncture on Shin-shu point for 3 days, followed by cisplatin injection(5mg/kg body weight). Results : 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-induced animals, which was partially prevented by Semen Plantaginis Herbal-Acupuncture treatment. Cisplatin injection increased lipid peroxidation, which was not prevented by Semen Plantaginis Herbal-Acupuncture. Conclusions : These results indicate that lipid peroxidation plays a critical role in cisplatin-induced acute renal failure. Semen Plantaginis Herbal-Acupuncture exerts the protective effect against acute renal failure induced by cisplatin, and its effect may be attribued to an antioxidant action.

The protective effect of OjB was dose-dependent over concentration range of 0.05-0.5%. H2O2 caused ATP depletion and DNA damage, which were prevented by OjB and the hydrogen peroxide scavenger catalase. The loss of cell viability by H2O2 was not affected by the antioxidant DPPD, but lipid peroxidation by the oxidant was completely inhibited by DPPD. Generation of superoxide and H2O2 in neutrophils activated by phorbol-12,13-dibutyrate was inhibited by OjB in a dose-dependent manner. OjB inhibited generation of H2O2 in OK cells treated with antimycin A and exerted a direct H2O2 scavenging effect. Exposure of OK cells to 1 mM tBHP caused a significant depletion of glutathione which was prevented by OjB. OjB accelerated the recovery in cells cultured for 20 hr in normal medium without oxidant following oxidative stress. Conclusions : These results suggest that OjB exerts the protective effect against oxidant-induced cell injury and its protective effect was resulted from radical scavenging and antioxidant activities.

This study was undertaken to determine if Juglandis Semen Aquacupuncture(Ja) has a protective effect against glycerol-induced acute renal failure in rats. Rats were dehydrated for 24hr and then injected with $5m{\ell}/kg$ of 50% glycerol, one-half of dose in each hindlimb muscle. In experiments for Ja effect, rats received $0.1m{\ell}$ of Ja extraction in both sides of corresponding $Sh{\grave{e}}ns{\bar{u}}$($BL_{23}$) of human body and non-acupuncture points(the root of tail) for 3 days after injection of glycerol. The experimental group were divided into the Normal group, the Control group, the Ja to $Sh{\grave{e}}ns{\bar{u}}$($BL_{23}$) group(Ja-AS), the Ja to non-acupuncture points group(Ja-AN). There were significant decrease of Urine vollume, total protein and phosphate level in Ja-AS as compared with the control group. There were not any significant change of Urine creatinine in Ja-AS as compared with the control group. There were significant decrease of Unine glucose in Ja-AS, Ja-AN as compared with the control group. This suggests that Ja-AS could be used in prevention and treatment of acute renal failure. However, the precise mechanisms of Ja protection remain to be determined.

This study was undertaken to determine if Plantaginis Semen Herbal Acupuncture(PSA) has a protective effect against glycerol-induced acute renal failure in rats. Rats were dehydrated for 24hr and then injected with 8 ml/kg of $50\%$ glycerol, one-half of dose in each hindlimb muscle. In experiments for PSA effect, rats received 0.1 ml of PSA extraction in both sides of corresponding Shenso($BL_{23}$) of human body for 3 days after injection of glycerol. The experimental group were di vided into the Normal group, the Control group, the PSA group. Glycerol injection decreased glomerular filtration rate and increased urine volume, serum creatinine, BUN level and fractional excretion of glucose, $Na^+$, $K^+$ and $CI^-$. These result show that glycerol injection result in acute renal failure. PSA significantly increased glomerular filtration rate and significantly decreased serum creatinine, BUN level and fractional excretion of glucose, $Na^+$ and $CI^-$ as compared Control group. This suggests that PSA could be used in prevention and treatment of acute renalfailure. However, the precise mechanisms of PSA protection remain to be determined.
