Objectives : This study was designed to investigate the effects of Alismatis Rhizoma (AR) pharmacopuncture at BL23 on acute renal failure induced by cisplatin. Methods : The Sprague-Dawley rats were divided into Normal group (no injection of cisplatin and no treatment), Control group (cisplatin injection without treatment), Acu group (needling at BL23 after cisplatin injection), AR-PA1 group (treated with $0.3571mg/kg/20{\mu}l$ of AR pharmacopuncture at BL23 after cisplatin injection), and AR-PA2 group (treated with $1.7855mg/kg/20{\mu}l$ of AR pharmacopuncture at BL23 after cisplatin injection). Each treatment was given once daily for 8 days. Changes in body weight, kidney weight, tumor necrosis factor-alpha ($TNF-{\alpha}$), interleukin-6 (IL-6), Cu-Zn superoxide dismutase (Cu-Zn SOD), glutathione peroxidase (GPx), serum blood urea nitrogen (serum BUN), and serum creatinine were observed. Results : Body weight was significantly increased in AR-PA1 on $4^{th}$ and $6^{th}$ days and AR-PA2 on $2^{nd}$ day. $TNF-{\alpha}$ was significantly decreased in Acu, AR-PA1 and AR-PA2 groups. Cu-Zn SOD was significantly increased in AR-PA2 group. GPx was significantly increased in AR-PA1 and AR-PA2 groups. But kidney weight, IL-6, serum BUN and serum creatinine were not significantly changed in any groups compared to control group. Conclusions : In acute renal failure induced by cisplatin, AR pharmacopuncture has a mitigating effect on the inflammatory reaction related to the increase of $TNF-{\alpha}$ in the kidney tissue and a protective effect on the oxidative stress of the kidney tissue. However it is unlikely to restore the glomerular function or inhibit the renal swelling.

Houttuynia Cordata thunb has been used as folk medicine for analgesics, beriberi, edema, hepatitis and icterus etc. We investigated, the effects of Houttuynia Cordata thunb administration on protective in liver of 2,3,7,8-tetrachlorodibenzo-p-dioxin(TCDD) treated rats. Seven days after the injection of TCDD(1${\mu}g$/kg), Houttuynia Cordata thunb (200mg/kg) was administered into rats intraperitoneally for four weeks. We examined the antioxidative enzymatic activity by measuring the level of GOT, GPT in serum and MDA, GSH, GSSG, GPx, SOD and Catalase in liver tissue of rats. GOT activity of Houttuynia Cordata thunb and TCDD administered group(HTT) showed 49.00% of inhibitive effect compared to TCDD-treated abnormal group(TTA). GPT level of HTT group was decreased to the level of Non TCDD-treated group(NTT). MDA content in the TTA group was 1.27 times increased compared to NTT group. HTT group was inhibited by 69.53% compared to TTA group. GSH contents in HTT group was 1.91 times increased compared to TTA group. GSSG contents in HTT group was 46.72% decreased compared to TTA group. SOD and Catalase in TTA group were lower than in NTT group, but SOD and Catalase in HTT group were increased by 82% and 55.45% respectively compared to TTA group.

Objective: The study was conducted to evaluate the effects of night light regimen on growth performance, antioxidant status and health of Lingnan Yellow broiler chickens from 1 to 21 days of age. Methods: A completely randomized factorial design involved 2 photoperiods (constant lighting [CL], 24 L:0 D and intermittent lighting [INL], 17 L:3 D:1 L:3 D)${\times}2$ light intensities (10 lx and 30 lx). A total of one thousand six hundred and eighty 1-d-old Lingnan Yellow broiler chicks were randomly divided into 4 treatments with 6 replicates (70 birds per replicate). The experiment lasted for 21 d. Results: Photoperiods and light intensities had no effect on average daily gain, feed conversion ratio, and mortality of the broiler chickens (p>0.05). The INL had a significant effect on average daily feed intake (p<0.05) of broiler chickens compared with CL. Photoperiod and light intensity had an interactive effect on melatonin (MT) concentration (p<0.05). At CL, reducing light intensity increased MT concentration; INL birds had higher MT but MT concentration was not affected by light intensity. There was an interactive effect on glutathione peroxidase (GPx) and catalase (CAT) in serum and total antioxidant capability (T-AOC) in liver between photoperiod and light intensity. With the decrease of light intensity, the activities of GPx and CAT in serum and T-AOC in liver increased in CL group (p<0.05). Broiler chickens reared under INL had better antioxidant status and 10 lx treatments had higher activities of CAT in serum than 30 lx (p<0.05). Different photoperiods and light intensities had no effect on malondialdehyde. There was an interaction between photoperiod and light intensity on serum creatine kinase (CK) concentration (p<0.05). At CL, the elevated light intensity resulted in an increase in CK content; INL birds had lower CK concentration especially in low light intensity group. Besides, INL and low light intensity significantly reduced the concentration of serum corticosterone and heat shock protein 70 (p<0.05). Serum immunoglobulin M contents were increased in broiler chickens reared under the INL compared with CL group (p<0.05). Conclusion: Results above suggest that the night light regimen of INL and 10 lx could be beneficial to the broiler chickens from 1 to 21 days of age due to the better health status and electricity savings.

Purpose: Many studies have suggested that neuronal cells protect against oxidative stress-induced apoptotic cell death by polyphenolic compounds. We investigated the neuroprotective effects and the mechanism of action of Momordica charantia ethanol extract (MCE) against $H_2O_2-induced$ cell death of human neuroblastoma SK-N-MC cells. Methods: The antioxidant activity of MCE was measured by the quantity of total phenolic acid compounds (TPC), quantity of total flavonoid compounds (TFC), and 2,2-Diphenyl-1-pycrylhydrazyl (DPPH) radical scavenging activity. Cytotoxicity and cell viability were determined by CCK-8 assay. The formation of reactive oxygen species (ROS) was measured using 2,7-dichlorofluorescein diacetate (DCF-DA) assay. Antioxidant enzyme (SOD-1,2 and GPx-1) expression was determined by real-time PCR. Mitogen-activated protein kinases (MAPK) pathway and apoptosis signal expression was measured by Western blotting. Results: The TPC and TFC quantities of MCE were 28.51 mg gallic acid equivalents/extract g and 3.95 mg catechin equivalents/extract g, respectively. The $IC_{50}$ value for DPPH radical scavenging activity was $506.95{\mu}g/ml$ for MCE. Pre-treatment with MCE showed protective effects against $H_2O_2-induced$ cell death and inhibited ROS generation by oxidative stress. SOD-1,2 and GPx-1 mRNA expression was recovered by pre-treatment with MCE compared with the presence of $H_2O_2$. Pre-treatment with MCE inhibited phosphorylation of p38 and the JNK pathway and down-regulated cleaved caspase-3 and cleaved PARP by $H_2O_2$. Conclusion: The neuroprotective effects of MCE in terms of recovery of antioxidant enzyme gene expression, down-regulation of MAPK pathways, and inhibition apoptosis is associated with reduced oxidative stress in SK-N-MC cells.

Today, as the specification of pigs increases, it is important to develop eco-friendly livestock feeds that do not add antibiotics to highly utilizable materials as feed resources, and to produce functional eco-friendly pork and processed products. The purpose of this study was to establish Rubus occidentalis (RO) byproducts containing various amounts of physiologically active substances such as anticancer, anti - inflammation and antioxidant as a raw material for pig feed. The multifaceted efficacy of the RO fermented fodder (ROFF) was confirmed by the nutrient transport factors and antioxidant activity of Berkshire pigs. ROFF was added 0.3% to the general diet and the efficacy was confirmed by feeding diets to Berkshire pigs according to each weight for 43~73 days. As a result, the total cholesterol (TC), LDL-cholesterol (LDL-C) and HDL-cholesterol (HDL-C) levels were decreased or were increased in the castrated male and female Berkshire pigs but not significantly. It was confirmed that the tendency was improved in nutrition physiology. The biochemical levels of female finishing pigs were not significant but increased. In the case of finishing pigs with possibility of pregnancy, it is expected that the nutrition supply for piglet production and will help in the production of the healthy piglet. Transferrin (TFE) levels tended to increase in female growing pig and 110-150 kg finishing pigs. Thus ROFF could minimize the negative effects of iron contents deficiency in female Berkshire pigs. Glutathione peroxidase 1 (GPx1) activity was increased in castrated male and female 110-150 kg finishing pigs. Therefore, ROFF tends to improve the antioxidant capacity. The results of this study suggest that ROFF is one of the most favorable dietary sources when considering the contents of RO in feed. In particular, ROFF could have a positive effect on nutrient transport and iron content of female rather than castrated male Berkshire pigs.

Objectives : This study was performed to investigate the effects of $LR_3$ and $SP_6$ acupuncture on renal damage in streptozotocin(STZ)-induced diabetic mice. Methods : ICR male mice were stabilized for a week and divided into four groups: a normal mice group(N), no-acupuncture diabetic mice group(Control), $LR_3$ acupuncture diabetic mice group($LR_3$), and $SP_6$ acupuncture diabetic mice group($SP_6$). Diabetes was experimentally induced by intraperitoneal injection of STZ(150 mg/kg) in citrate buffer(pH 4.5). For two weeks, $LR_3$ and $SP_6$ acupunctures were administered bilaterally at each point once a day. After two weeks, the animals' weight was measured and they underwent a laparotomy. Serum glucose and blood urea nitrogen(BUN) were measured from the blood taken from the heart. We measured glucose, reactive oxygen species(ROS), peroxynitrite($ONOO^-$) and thiobarbituric acid reactive substances(TBARS) in the kidney and compared expression levels of superoxide dismutases(SOD), glutathione peroxidase(GPx), nuclear factor-kappa B(NF-${\kappa}B$), cyclooxygenase-2 (COX-2), inducible nitric oxide synthase(iNOS) and Interleukin-1 beta(IL-$1{\beta}$). Results : BUN significantly decreased in $LR_3$, $SP_6$ compared to the control group. $LR_3$ showed significantly decreased glucose compared to the control group. $LR_3$, $SP_6$ significantly decreased in ROS and $ONOO^-$ compared to the control group. $LR_3$ significantly decreased in TBARS compared to the control group. $SP_6$ significantly increased in expressions of SOD-1, catalase, and GPx compared to the control group. $LR_3$, $SP_6$ significantly decreased in COX-2 compared to the control group. $SP_6$ significantly decreased in IL-$1{\beta}$ compared to the control group. Conclusions : This study suggests that $LR_3$ acupuncture may be effective in controlling glucose and lipid peroxidation and that $SP_6$ acupuncture may have anti-oxidative and anti-inflammatory effects on renal damage in STZ-induced diabetic mice.

A mechanism of hair cell damage caused by noise and ototoxic agents is mediated through generation of free radicals and reactive oxygen species (ROS). It is known that most of animals have defense systems to protect against ROS, and the cochlea of inner ear in animals also has ROS defense systems including several antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX), glutathione reductase (GR), and glutathione (GSH), which efficiently detoxifying ROS generated under normal condition. Steamed roots of Rehmannia glutinosa have been traditionally used in Oriental medicine for the treatment of auditory disease such as tinnitus, vertigo, and hearing loss as well as inflammatory diseases, hectic fever, night sweat, and headache. In the present study, we showed that the ethanol extract from steamed roots of R. giutinosa (ESRG) increased the antioxidant enzymes such as SOD, CAT, GPX, and GR activities and GSH level in HEI-OC1 auditory cells. This extract itself did not show any significant cytotoxicity up to $50{\mu}g/ml$. Our results further support the view that ESRG is promising sources of potential antioxidants. Future studies will be aimed at investigating the effects of ESRG on the regulation of cellular mechanisms and isolating and identifying the substances responsible for the regulation of antioxidant enzyme system from the plant extracts.

Styrene is a commercially important chemical used mainly in the production of plastics. A toxic effect exerted by styrene exposure may cause infertility, congenital anomalies or death in offspring. Treatment with styrene for 0, 50, 100, and 500 mg/kg for 5 days in Sprague-Dawley rats significantly decreased sperm motilities and sperm counts while sperm abnormalities were significantly increased. To determine the relationship between changes in sperm motilities and roles of reactive oxygen species (ROS), we determined the effect of styrene on ROS production and mRNA expression of antioxidant enzymes in rats. ROS production was enhanced by styrene treatment in a dose-dependent manner. The mRNA expression of catalase and superoxide dismutase (SOD) 2 was strongly suppressed by styrene treatment although SOD1 or glutathione peroxidase (GPX) 4 expressions were not significantly changed. Taken together, these results indicate that styrene may cause toxic effect in rat sperm cells by enhancing oxidative stresses.

To investigate the deaging effects of introperitoneally injected Chondroitin Sulfate (CS) on various enzyme activity (AST, ALT, MDA (Malon dialdehyde), SOD (Superoxide dismutase), GPx (Glutathione peroxidases) and histophathology of liver tissue, ovariectomized rats were used. The antioxidative effects of chondroitin sulfate (100 mg/kg and 200 mg/kg body weight) were investigated at the antioxidative enzyme activities of liver homogenate fractions (liver total homogenate, mitochondrial, and microsomal fractions) and sera. In addition, the rat liver was histologically examined. Intraperitoneally injected CS, depend on dosage, indicated a protective effect against ovariectomy-inducted aging. Moreover, inflammation and cirrhosis in liver tissue of CS treated group were significantly decreased. Based on these results, intraperitoneally injected CS is a useful material to delay aging.
