Abstract
Astragalus membranaceus is a traditional Chinese medicine with multiple pharmacological activities. Modern pharmacological research has found that Astragalus membranaceus extract has an inhibitory effect on α-glucosidase, however, which component can inhibit the activity of α-glucosidase and its degree of inhibition are unknown. To address this issue, this study used affinity ultrafiltration screening combined with UPLC-ESI-Orbitrap-MS technology to screen α-glucosidase inhibitors in Astragalus membranaceus. Using affinity ultrafiltration technology, we obtained the active components, and using UPLC-ESI-Orbitrap-MS technology, we quickly analyzed and identified them. As a result, a total of 8 ingredients were selected as α-glucosidase inhibitors.

Abstract
The effects of substituting Bacillus subtilis, Astragalus membranaceus, and enzymes for aureomycin to improve the growth performance of broilers during specific phases were studied to develop alternatives to in-feed antibiotics and decrease drug residues in meat food and antibiotic resistance. Six hundred one-day-old broilers were randomly assigned to 5 groups. Broilers in the control group were supplied with basal diets (CT), and those in the remaining 4 groups were supplied with feed containing aureomycin premix (AU), B. subtilis powder (BS), A. membranaceus root powder (AM), and enzyme compound powder (EN), respectively. Compared to the control group, broilers in the other groups exhibited better growth performance during different phases. Microbial analysis of cecal contents suggested that treatment with BS or EN significantly increased the abundance of Lactobacillus or Bifidobacteria but inhibited Escherichia coli or Clostridium welchii; however, these bacteria were suppressed by AU treatment except C. welchii. The digestibility of the feed in vitro was significantly enhanced by adding BS or EN to the feed, consistent with findings for growth performance. In conclusion, dietary supplementation with 3 additives could improve the growth performance of broilers during specific phases. Future studies should focus on designing suitable schedules to partially replace in-feed antibiotics.

Abstract
Hyperuricemia (HUA) is a common metabolic disease that is an independent risk factor for comorbidities such as hypertension, chronic kidney disease, and coronary artery disease. The prevalence of HUA has increased over the last several decades with improved living standards and increased lifespans. Metabolites are considered the most direct reflection of individual physiological and pathological conditions, and represent attractive candidates to provide deep insights into disease phenotypes. Metabolomics, a technique used to profile metabolites in biofluids and tissues, is a powerful tool for identification of novel biomarkers, and can be used to provide valuable insights into the etiopathogenesis of metabolic diseases and to evaluate the efficacy of drugs. In this study, multi metabolomics-based analysis of the blood, urine, and feces of rats with HUA showed that HUA significantly altered metabolite profiles. Astragalus membranaceus (AM) and benbromomalone significantly mitigated these changes in blood and feces, but not in urine. Some crucial metabolic pathways including lipid metabolism, lipid signaling, hormones synthesis, unsaturated fatty acid (UFAs) absorption, and tryptophan metabolism, were seriously disrupted in HUA rats. In addition, AM administration exerted better treatment effects on HUA than benbromomalone. Furthermore, additional supplementation with UFAs and tryptophan may also induce therapeutic effects against HUA.

Sesamin Protects against and Ameliorates Rat Intestinal Ischemia/Reperfusion Injury with Involvement of Activating Nrf2/HO-1/NQO1 Signaling Pathway. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:5147069. [PMID: 34630849 PMCID: PMC8494576 DOI: 10.1155/2021/5147069] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Revised: 08/06/2021] [Accepted: 08/11/2021] [Indexed: 02/06/2023]
Abstract
Intestinal ischemia-reperfusion (I/R) may induce cell/tissue injuries, leading to multiple organ failure. Based on our preexperiments, we proposed that sesamin could protect against and ameliorate intestinal I/R injuries and related disorders with involvement of activating Nrf2 signaling pathway. This proposal was evaluated using SD intestinal I/R injury rats in vivo and hypoxia/reoxygenation- (H/R-) injured rat small intestinal crypt epithelial cell line (IEC-6 cells) in vitro. Sesamin significantly alleviated I/R-induced intestinal histopathological injuries and significantly reduced serum biochemical indicators ALT and AST, alleviating I/R-induced intestinal injury in rats. Sesamin also significantly reversed I/R-increased TNF-α, IL-6, IL-1β, and MPO activity in serum and MDA in tissues and I/R-decreased GSH in tissues and SOD in both tissues and IEC-6 cells, indicating its anti-inflammatory and antioxidative stress effects. Further, sesamin significantly decreased TUNEL-positive cells, downregulated the increased Bax and caspase-3 protein expression, upregulated the decreased protein expression of Bcl-2 in I/R-injured intestinal tissues, and significantly reversed H/R-reduced IEC-6 cell viability as well as reduced the number of apoptotic cells among H/R-injured IEC-6 cell, showing antiapoptotic effects. Activation of Nrf2 is known to ameliorate tissue/cell injuries. Consistent with sesamin-induced ameliorations of both intestinal I/R injuries and H/R injuries, transfection of Nrf2 cDNA significantly upregulated the expression of Nrf2, HO-1, and NQO1, respectively. On the contrary, either Nrf2 inhibitor (ML385) or Nrf2 siRNA transfection significantly decreased the expression of these proteins. Our results suggest that activation of the Nrf2/HO-1/NQO1 signaling pathway is involved in sesamin-induced anti-inflammatory, antioxidative, and antiapoptotic effects in protection against and amelioration of intestinal I/R injuries.

Abstract
OBJECTIVE Previous studies have shown that Astragalus polysaccharides (APS) and Astragaloside IV (AS-IV) protect against inflammation-related cell damage and exhibit immune enhancement. Since urothelial injury may result in an overactive bladder (OAB), the aim of this study was to investigate the efficacy of APS and AS-IV on urothelial injury in an experimental animal model. MATERIALS AND METHODS The effects of APS and AS-IV on the proliferation and migration of primary human urothelial cells (HUCs) or primary human fibroblast cells (HFCs) were assessed using an in vitro wounding model and colorimetric thiazolyl blue assays. Sixty virgin female mice were randomized into five groups: group 1-saline-injected plus treatment with H2O, group 2-cyclophosphamide (CYP) plus treatment with H2O, group 3-CYP plus treatment with solifenacin succinate (SS; 10 mg/kg), group 4-CYP plus treatment with AS-IV (100 mg/kg), and group 5-CYP plus treatment with APS (100 mg/kg). Cystometry assessment was conducted and cell junction-associated protein zonula occludens-2 (ZO-2) expression was measured. Voiding interval values (time between voids) were assessed in mice under anesthesia. Lastly, immunohistochemistry analysis was used to confirm the location and level, respectively, of ZO-2 expression. RESULTS APS and AS-IV did not influence the cell viability but increased migration in HFCs compared with the controls. The OAB mice showed significantly lower voiding interval values. Voiding interval values were significantly higher in the CYP plus treatment with APS (100 mg/kg) and AS-IV (100 mg/kg) groups than in the CYP-induced OAB group. Additionally, the expression of ZO-2, a tight junction protein, was increased in the CYP plus treatment APS (100 mg/kg) and AS-IV (100 mg/kg) groups compared with the CYP-induced OAB group. CONCLUSION These findings suggest that APS and AS-IV modulate urothelial wound healing, which ameliorates urinary frequency of mice treated with CYP. APS or AS-IV may have the potential benefit of acting as urothelial wound healing modulators.

Abstract
Electroacupuncture (EA) at ST36 can improve the survival rate in rats after hemorrhagic shock (HS). The current study investigated rats with 60% blood loss. 144 rats were divided into four groups: hemorrhage without fluid resuscitation (HS), EA after hemorrhage without fluid resuscitation (EA), hemorrhage with delayed resuscitation (DFR), and EA after hemorrhage with delayed resuscitation (EA + DFR). The survival rate and biological parameters 0, 3, 12, and 24 h after HS were investigated. The 24 h survival rate of EA + DFR was significantly higher than that of DFR. 12 h after hemorrhage, the level of mean arterial blood pressure of EA + DFR was significantly higher than that of DFR, and the levels of renal blood flow, intestinal mucosal blood flow, and hepatic blood flow of EA + DFR were also significantly higher than those of DFR. Three hours after hemorrhage, the levels of lactate, PaCO2, alanine aminotransferase, and creatinine of groups receiving EA were significantly lower than those of non-EA groups, and the levels of pH, PaO2, and diamine oxidase of groups receiving EA were significantly higher. EA at ST36 can improve the 24 h survival rate and produce the experimental antishock effects on tissue perfusion and organ protection from fatal HS.

A mixture of daidzein and Chinese herbs increases egg production and eggshell strength as well as blood plasma Ca, P, antioxidative enzymes, and luteinizing hormone levels in post-peak, brown laying hens. Poult Sci 2019; 98:3298-3303.

Abstract
Dietary supplementation with the isoflavone, daidzein, has been shown to improve egg production in poultry. Additionally, providing Chinese herbs (CH) in the broiler diet has led to increased antioxidative enzyme activity. However, the combined effect of these dietary supplements on hen performance has not been examined. Therefore, the objective of this study was to determine if dietary supplementation with a mixture of daidzein and CH would alter laying performance, egg quality, and blood plasma constituents of post-peak laying hens. At 59 wk of age, Hyline brown hens (240) were randomly allocated to 2 dietary groups and fed for 16 wk. The control group received the basal diet, and a treatment group was fed the basal diet that contained 0.02% of a mixture of daidzein and CH. Egg production and weight were recorded daily and egg quality data were collected at 75 wk of age. Blood plasma antioxidant activity, hormone levels, mineral (Ca and P) content, and osteocalcin content were determined at the end of the study. The results showed that laying rate, egg mass, and shell strength were greater in the daidzein-CH mixture group than the controls (P < 0.05). The plasma glutathione peroxidase, superoxide dismutase, and luteinizing hormone levels were also greater in the daidzein-CH mixture group compared with the control group (P < 0.05). The results of this study reveal that supplementing diets with a daidzein-CH mixture can improve laying performance perhaps by increasing plasma antioxidant activity, luteinizing hormone levels, and mineral content.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Astragali radix (Huang Qi, HQ), a well-known Chinese herbal medicine, is widely coadministered with many other drugs for treating diseases. The potential herb-drug interactions (HDIs) possibly occur during the combination therapy. P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) are the crucial targets that mediate the production of HDIs. We previously observed that HQ and its three main bioactive compounds, including Astragaloside IV (AS-IV), calycosin (CS) and formononetin (FMNT), could significantly induce the expression of P-gp and BCRP in HepG2 cells in vitro. However, their modulations on the function of P-gp and BCRP remain unknown; their impact on these two proteins expression in vivo is not clear; the exact regulatory mechanism has also not yet been explored. AIM OF THE STUDY This study aimed to investigate the impact of HQ, AS-IV, CS and FMNT on P-gp and BCRP in vivo, and the exact regulatory mechanism involved. The effects of HQ and these compounds on the function of P-gp and BCRP were also studied. MATERIALS AND METHODS Wild-type C57BL/6 mice and nuclear factor E2-related factor-2 knockout (Nrf2-/-) C57BL/6 mice were orally treated with HQ, AS-IV, CS or FMNT. The protein levels of P-gp and BCRP in the liver of mice were measured by using Western blot and immunohistochemistry. The mRNA levels were measured by using real-time PCR. The activation of the drugs on the antioxidant response element (ARE)-luciferin activity was studied by using reporter assay in a stably transfected HepG2-C8 cells. The efflux activity of P-gp and BCRP in HepG2 cells were tested by using flow cytometer with typical probes. RESULTS HQ, AS-IV, CS and FMNT significantly upregulated the P-gp and BCRP expression in the liver of wild-type mice. The induction was significantly reversed in the Nrf2-/- mice. HQ and these compounds significantly increased the Nrf2 expression in wild-type mice. HQ and these compounds also markedly enhanced the ARE-luciferin activity and promoted the nuclear translocation of Nrf2 in cells. Besides, HQ and these compounds significantly enhanced the efflux activity of P-gp and BCRP, and increased the intracellular ATP levels. CONCLUSIONS Our results proved that HQ and its main bioactive compounds could induce the P-gp and BCRP expression through the activation of the Nrf2-mediated signaling pathway. HQ and these compounds also significantly enhanced the efflux activity of P-gp and BCRP, and the increased intracellular ATP levels were likely involved in the increased P-gp and BCRP function. These results suggested that potentially HDIs likely occurred when HQ was used concomitantly with other drugs that are substrates of P-gp and BCRP.

Abstract
Selection of the appropriate method for traceability may be of great interest for the characterization of food authenticity and to reveal falsifications. The possibility of tracing the geographical origins of Radix Astragali based on diffuse reflectance mid-infrared Fourier transform spectroscopy (DRIFTS) technique and fluorescence fingerprints (EEMs) technique was investigated in this work. DRIFTS technique combined with PCA and PLS-DA and EEMs technique combined with M-PCA and N-PLS-DA were used to determine the geographical origin of Radix Astragali samples, respectively. DRIFTS-PLS-DA provided total recognition rates of 98.4% for all Radix Astragali samples in the training sets and 94.6% in the predicted sets. Compared with the DRIFTS, EEMs combined with chemometrics obtained more accurate recognition results. The total recognition rates (RRs) of the training sets and prediction sets obtained with EEMs-N-PLS-DA were all 100%. The good classification results of fluorescence fingerprints technique should be attributed mainly to two reasons. One reason is that three-dimensional fluorescence spectrum can provide more information than two-dimensional DRIFTS, and the other reason is that fluorescence spectrum has higher sensitivity and selectivity than the DRIFTS. Therefore, fluorescence fingerprint (EEMs) technique combined with chemometrics results more adequate for tracing the food geographical origin. It should be noted that the more the analysis target contains fluorescent substances, the more accurate results are obtained by using the fluorescent fingerprint method. Conversely, if the classification object contains very few fluorescent substances, the classification result may not be as good as the DRIFTS method. Furthermore, due to relatively cumbersome operation of fluorescence method, EEMs fluorescence method is unsuitable for rapid analysis as compared to infrared method.

Abstract
Astragalus membranaceus, dried root extract, also known as Astragali radix, is used in traditional Chinese medicine as a tonic remedy. Moreover, it has been reported that Astragalus membranaceus could attenuate intestinal inflammation; however, the underlying mechanism for its anti-inflammatory activity in intestinal epithelial cells (IECs) remains unclear. In this study, we evaluated Astragalus membranaceus extract (5-100 µg/mL) in a model of inflammation and oxidative stress for IECs. We showed that Astragalus membranaceus extract reduced the inflammatory response induced by lipopolysaccharide from E. coli (LPS) plus interferon-γ (IFN), decreasing tumor necrosis factor-α (TNF-α) release, cycloxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) expression, nitrotyrosine formation, nuclear factor-κB (NF-κB) activation, and reactive oxygen species (ROS) release in the non-tumorigenic intestinal epithelial cell line (IEC-6). The antioxidant potential of Astragalus membranaceus extract was also evaluated in a model of hydrogen peroxide (H₂O₂)-induced oxidative stress in IEC-6, indicating that this extract reduced ROS release and increased nuclear factor (erythroid-derived 2)-like 2 (Nrf2) activation and the expression of antioxidant cytoprotective factors in these cells. The results contributed to clarify the mechanisms involved in Astragalus membranaceus extract-reduced inflammation and highlighted the potential use of this extract as an anti-inflammatory and antioxidant remedy for intestinal diseases.

Abstract
Owing to a dramatic increase in average life expectancy and the Family Planning program of the 1970s - 1990s, China is rapidly becoming an aging society. Therefore, the investigation of healthspan-extending drugs becomes more urgent. Astragalus membranaceus (Huangqi) is a major medicinal herb that has been commonly used in many herbal formulations in the practice of traditional Chinese medicine (TCM) to treat a wide variety of diseases and body disorders, or marketed as life-prolonging extracts for human use in China, for more than 2000 years. The major components of Astragalus membranaceus are polysaccharides, flavonoids, and saponins. Pharmacological research indicates that the extract component of Astragalus membranaceus can increase telomerase activity, and has antioxidant, anti-inflammatory, immunoregulatory, anticancer, hypolipidemic, antihyperglycemic, hepatoprotective, expectorant, and diuretic effects. A proprietary extract of the dried root of Astragalus membranaceus, called TA-65, was associated with a significant age-reversal effect in the immune system. Our review focuses on the function and the underlying mechanisms of Astragalus membranaceus in lifespan extension, anti-vascular aging, anti-brain aging, and anti-cancer effects, based on experimental and clinical studies.

Abstract
Astragalus polysaccharide (APS) is a bioactive extract of Astragalus membranaceus (AM), which possess a wide range of medicinal benefits, including anti-inflammatory, anti-oxidative, anti-tumor and anti-diabetic effects. The present work evaluated the therapeutic effect of APS and its potential mechanisms in a mouse model of dextran sulfate sodium (DSS)-induced colitis. The APS treatment led to significant improvements in colitis disease activity index (DAI) and histological scores, as well as significantly increased weight and colon length in mice as compared to the control group. Mechanically, reduced NF-κВ DNA phosphorylation activity and downregulated TNF-α, IL-1β, IL-6, IL-17 expressions and myeloperoxidase (MPO) activity were associated with improvement in colitis observed in APS-treated mice. These findings suggest that APS may represent a natural therapeutic approach for treating inflammatory bowel disease, such as ulcerative colitis.

Abstract
BACKGROUND Chromolena odorata is a tropical species of flowering shrub in the family Asteraceae, leaves of it have been reported to be widely used as herbal remedy for the treatment of various ailments. It is particularly reported to be useful in the healing of wounds. METHODS We investigated the possibility of amelioration of intestinal ischemia-reperfusion (IR) injury in rats treated with methanolic extract of C. odorata (MECO). Wistar albino rats were divided randomly into five groups of six animals each as control, IR-treated, IR+200 mg/kg MECO, IR+400 mg/kg MECO, and IR+200 mg/kg vitamin C. Pre-treatment with MECO or vitamin C was for 7 days. RESULTS The contents of hydrogen peroxide (H2O2) and malondialdehyde (MDA) were significantly reduced by MECO and vitamin C, while there were significant enhancements of the activities of superoxide dismutase (SOD), glutathione peroxidase (GPX), catalase (CAT), as well as the content of reduced glutathione (GSH) in pre-treated rats compared to IR-treated rats. Glutathione S-transferase (GST) activity was not significantly affected in all the groups. Histopathological examination of small intestinal mucosa revealed significant attenuation of intestinal pathology in animals pre-treated with MECO, while IR injury produced severe villi erosion, necrosis, and inflammatory cell infiltrations. CONCLUSIONS The present study highlights the antioxidant activities of MECO and its ability to inhibit inflammatory cell infiltration as mechanisms involved in its protection against IR injury in the intestine of rats, an effect that was largely comparable to that of vitamin C.

Abstract
Severe burn injuries may result in gastrointestinal paralysis, and barrier dysfunction due to gut ischemia and lowered vagus excitability. In this study we investigate whether electroacupuncture (EA) at Zusanli (ST36) could prevent severe scalds-induced gut ischemia, paralysis, and barrier dysfunction and whether the protective role of EA at ST36 is related to the vagus nerve. 35% burn area rats were divided into six groups: (a) EAN: EA nonchannel acupoints followed by scald injury; (b) EA: EA at ST36 after scald injury; (c) VGX/EA: vagotomy (VGX) before EA at ST36 and scald injury; (d) VGX/EAN: VGX before EAN and scald injury; (e) atropine/EA: applying atropine before scald injury and then EA at ST36; (f) atropine/EAN: applying atropine before scald injury and then EA at nonchannel acupoints. EA at the Zusanli point significantly promoted the intestinal impelling ratio and increased the amount of mucosal blood flow after scald injury. The plasma diamine oxidase (DAO) and intestinal permeability decreased significantly after scald injury in the EA group compared with others. However, EA after atropine injection or cervical vagotomy failed to improve intestinal motility and mucosa blood flow suggesting that the mechanism of EA may be related to the activation of the cholinergic nerve pathway.

Abstract
BACKGROUND Astragalus membranaceus (AM) is a Chinese traditional herb which has been reported to have broad positive effects on many diseases, including hepatitis, heart disease, diabetes and skin disease. AM can promote cell proliferation, increase the activities of superoxide dismutase (SOD) and glutathione peroxidase (GPx), and inhibit apoptosis by regulating the transcription of proto-oncogenes controlling cell death. While AM is included in some commercially available "testosterone boosting supplements", studies directly testing ability of AM to modulate testosterone production are lacking. In the present study, we examined the effects of AM on Leydig cell function in vitro. METHODS Rat Leydig cells were purified and treated with AM at different concentrations (0 μg/mL, 10 μg/mL, 20 μg/mL, 50 μg/mL, 100 μg/mL and 150 μg/mL) and cell counting-8 (CCK-8) assay, Enzyme-linked immunosorbent assay, quantitative real time PCR and analysis of activities of SOD and GPx were done respectively. RESULTS Treatment with 100 μg/mL (P<0.05) and 150 μg/mL AM (P<0.01) significantly increased Leydig cell numbers. Treatment with AM (20 μg/mL, 50 μg/mL and 100 μg/mL) significantly increased testosterone production (P<0.01). In addition, increased Leydig cell SOD and GPx activities were observed in response to 20 μg/mL and 50 μg/mL AM treatment (P<0.01). Furthermore, expression of Bax mRNA was significantly decreased (P<0.01), and the ratio of Bcl-2/Bax mRNA was significantly increased in response to 20 μg/mL AM in the culture medium (P<0.05). CONCLUSIONS Results supported a beneficial effect of AM on multiple aspects of rat Leydig cell function in vitro including testosterone production.

Modulation of intestinal epithelial cell proliferation, migration, and differentiation in vitro by Astragalus polysaccharides. PLoS One 2014; 9:e106674.

Abstract
Previous studies have shown that Astragalus polysaccharides (APS) can be used to treat general gastrointestinal disturbances including intestinal mucosal injury. However, the mechanism by which APS mediate this effect is unclear. In the present study, the effects of APS on proliferation, migration, and differentiation of intestinal epithelial cells (IEC-6) were assessed using an in vitro wounding model and colorimetric thiazolyl blue (MTT) assays. The effect of APS on IEC-6 cell differentiation was observed using a light microscope and scanning electron microscope, and the expression of differentiation-specific markers of IEC-6 cells, such as cytokeratin 18 (CK18), alkaline phosphatase (ALP), tight junction protein ZO-2, and sucrase-isomaltase (SI), was determined by immunofluorescence assay (IFA) and real-time PCR. In addition, APS-induced signaling pathways in IEC-6 cells were characterized. Our results indicated that APS significantly enhance migration and proliferation of IEC-6 cells in vitro. APS-treated IEC-6 cells have numerous microvilli on their apical surface and also highly express CK18, ALP, ZO-2, and SI. Moreover, APS-treated IEC-6 cells, in which the activity and expression level of ornithine decarboxylase (ODC) were significantly elevated, also exhibited an increase in cellular putrescine, whereas no significant increase in TGF-β levels was observed. These findings suggest that APS may enhance intestinal epithelial cell proliferation, migration, and differentiation in vitro by stimulating ODC gene expression and activity and putrescine production, independent of TGF-β. Exogenous administration of APS may provide a new approach for modulating intestinal epithelial wound restitution in vivo.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lycium barbarum and Astragalus membranaceus are two traditional medicinal herbs widely used in China for nourishing Yin and reinforcing Qi. The purpose of the study was to investigate the prophylactic and curative effects of crude polysaccharides (QHPS) extracted from a two-herb formula composed of Lycium barbarum and Astragalus membranaceus at a ratio of 2:3 in colitis rats, and to further elucidate the potential mechanism of action in epithelial cell proliferation in vitro. MATERIALS AND METHODS An acetic acid (AA)-induced ulcerative colitis rat model was applied in the study. Two independent protocols were used to assess the prophylactic and curative effects of QHPS, respectively, in which rats were either pre-treated with QHPS (0.18g/kg) for 14 days prior to AA induction, or post-treated with QHPS for 7 days after AA induction. The stool consistency and weight loss were used to evaluate disease activity. The morphological changes in intestinal mucosa at the end of the experiments were observed. The serum levels of endotoxin (EDT), diamine oxidase (DAO) and d-lactate (DLA), important biochemical markers for evaluating intestinal mucosal structure and function, were measured. In the in vitro mechanistic studies, rat intestinal epithelial cells (IEC-6) were used to access for epithelium regeneration. RESULTS The intra-colonic instillation of AA induced ulcerative colitis in rat, as indicated by diarrhea, weight loss, and colonic mucosal damage. Both prophylactic and curative treatments effectively reduced the weight loss and diarrhea and attenuated the colonic mucosal damage associated with inducible colitis. The significant increase in serum levels of DAO, DLA and EDT was induced by AA and inhibited by QHPS treatment. Moreover, QHPS could significantly stimulate IEC-6 proliferation in a dose-dependent manner (p<0.05). CONCLUSION The present study indicated for the first time that polysaccharides extracted from this two-herb formula can protect against experimental ulcerative colitis, presumably by promoting the recovery of the intestinal barrier.

Abstract
Astragaloside IV (ASI) in Radix Astragali is believed to be the active component. The study aims to investigate whether ASI inhibits tubular epithelial cells apoptosis induced by high glucose and its mechanisms. Tubular epithelial cells in this paper were isolated from human kidney. The cells apoptosis was detected by TUNEL and caspase 3 assay. The protein levels of HGF and TGF-β1 were measured by ELISA. The phospho-p38 production, ERK and JNK were determined by Western blot. ASI could inhibit cells apoptosis induced by high glucose (25 mmol/L) in dose-dependent and time-dependent manners. ASI also inhibited high glucose-induced expression of TGF-β1 and activation of p38 MAPK pathway at the protein level. Furthermore, ASI increased HGF production in human tubular epithelial cells. The ASI inhibition of tubular epithelial cells apoptosis and reduction of TGF-β1 expression induced by high glucose may represent a new treatment for diabetic kidney injury. The mechanism underlying this inhibitory effect may be related to the inhibition of p38 MAPK signaling pathway activation and HGF overproduction.

Abstract
Plant-sourced formulations such as Iberogast and the traditional Chinese medicine formulation, Cmed, purportedly possess anti-inflammatory and radical scavenging properties. We investigated Iberogast and Cmed, independently, for their potential to decrease the severity of the large bowel inflammatory disorder, ulcerative colitis. Sprague Dawley rats (n = 8/group) received daily 1 mL gavages (days 0-13) of water, Iberogast (100 μL/200 μL), or Cmed (10 mg/20 mg). Rats ingested 2% dextran sulfate sodium or water ad libitum for 7 days commencing on day 5. Dextran sulfate sodium administration increased disease activity index scores from days 6 to 12, compared with water controls (P < .05). On day 10, 200 μL Iberogast decreased disease activity index scores in colitic rats compared with colitic controls (P < .05). Neither Iberogast nor Cmed achieved statistical significance for daily metabolic parameters or colonic crypt depth. The therapeutic effects of Iberogast and Cmed were minimal in the colitis setting. Further studies of plant extracts are required investigating greater concentrations and alternative delivery systems.

Abstract
CONCLUSION The results suggest that the beneficial effect of astragaloside IV on impulse noise-induced hearing loss may be due to its ability to inhibit reactive oxygen species (ROS) and prevent apoptosis. OBJECTIVE Astragaloside IV is the major active constituent of Astragalus membranaceus, which has been widely used for the treatment of diseases in China for its antioxidant properties. ROS and apoptosis are involved in damage induced by impulse noise trauma. We aimed to investigate if the beneficial effects of astragaloside IV on cochlea exposed to impulse noise are associated with the inhibition of ROS and the decrease in apoptosis. METHODS 4-Hydroxynonenal (HNE) was used as the marker of ROS. Active-caspase-3 (cas-3) served as a marker for apoptosis. 4HNE and cas-3 were determined immunohistochemically. Guinea pigs in the experimental group were administered astragaloside IV intragastrically. Auditory thresholds were assessed by sound-evoked auditory brainstem response (ABR) 72 h before and after exposure to impulse noise. RESULTS The results showed that astragaloside IV significantly reduced ABR deficits, and decreased the expression of ROS and cas-3.

Abstract
Astragalus membranaceus, also known as huang qi, a traditional Chinese medicine, is often used in formulas for deficiency of vital energy characterized by limb weakness, pale face, and dizziness. Previous studies have shown that Astragalus membranaceus could attenuate intestinal ischemia-reperfusion injury induced by hemorrhagic shock in rats; however, the underlying mechanism still remains unclear. Using a hemorrhagic shock rat model to examine the effect of Astragalus membranaceus on intestinal mucosa injury induced by ischemia-reperfusion, we found that treatment (20 g crude drugs/kg, i.v.) produced antioxidative effects in the intestinal mucosa of rats after ischemia-reperfusion (p < 0.05). We also found that Astragalus membranaceus could partly attenuate intestinal mucosa ischemia-reperfusion injury (chiu's score, apoptosis index p < 0.05). These results suggest that Astragalus membranaceus reduces intestinal mucosa injury induced by ischemia-reperfusion in rats, at least in part, through its anti-oxidative effects.

Abstract
CONCLUSION These results suggest that the beneficial effect of astragaloside IV on impulse noise-induced hearing loss may be due to its ability to inhibit inducible nitric oxide synthase (iNOS) and prevent the formation of reactive nitrogen species (RNS). OBJECTIVE Astragaloside IV is the major active constituent of Astragalus membranaceus, which has been widely used for the treatment of diseases in China due to its antioxidant properties. iNOS and RNS are involved in damage induced by impulse noise trauma. The purpose of the present study was to investigate if astragaloside IV has the potential to reduce cochlear damage from impulse noise. METHODS Guinea pigs in the experimental group were administered astragaloside IV intragastrically. Auditory thresholds were assessed by sound-evoked auditory brainstem response (ABR) at click and tone bursts of 8, 16 and 32 kHz, 72 h before and after exposure to impulse noise. iNOS and nitrotyrosine were determined immunohistochemically. Hair cell damage was analyzed by scanning electron microscopy. RESULTS Astragaloside IV significantly reduced ABR deficits, reduced hair cell damage, and decreased the expression of iNOS and RNS formation.

Abstract
Exacerbation of hypoxic injury after reoxygenation is a crucial mechanism mediating organ injury in transplantation, and in myocardial, hepatic, gastrointestinal, cerebral, renal, and other ischemic syndromes. The occlusion and reperfusion of the splanchnic artery is a useful animal model to elucidate the mechanism of gastrointestinal injury induced by ischemia-reperfusion (I/R). Although xanthine oxidase is a major source of reactive oxygen species (ROS), which plays an important role in the I/R-induced intestinal injury, there are many other sources of intracellular ROS. Various treatment modalities have been successfully applied to attenuate the I/R injury in animal models. This review focuses on the role of oxidant stress in the mechanism of I/R injury and the use of antioxidant agents for its treatment.

Abstract
Cisplatin is known to cause high-frequency neurosensory hearing loss. While reactive oxygen species have been shown to play a role, reactive nitrogen species have been implicated, but not proven to be involved, in cisplatin ototoxicity. The purpose of the present study was to investigate the role of nitric oxide (NO) in cisplatin ototoxicity by administering astragalosides, a natural antioxidant, in conjunction with cisplatin. Guinea pigs were injected with cisplatin, astragalosides or both. Auditory brainstem-evoked responses (ABRs) were measured before and 3 days after cisplatin administration. The cochlear tissue was then assayed for NO and malondialdehyde (MDA), and cochleae were also examined by scanning electron microscopy. Cisplatin alone caused significant ABR threshold shifts at all stimuli tested, whereas astragalosides alone caused no shifts. There was a significant reduction in threshold shift for clicks, 8-kHz and 16-kHz tone bursts (but not 32 kHz) when astragalosides was given with cisplatin. Both the MDA concentration and the NO concentration in the astragalosides/cisplatin group were significantly lower than those of the cisplatin group. Correspondingly, the loss of outer hair cells in the astragalosides/cisplatin group was much less than that in the cisplatin group. This suggests that astragalosides reduces cisplatin ototoxicity by its antioxidant property.

Abstract
AIM: To explore the effect of Astragalus mongholicus polysaccharide (APS) on gene expression and mitogen-activated protein kinase (MAPK) transcriptional activity in intestinal epithelial cells (IEC).
METHODS: IEC were divided into control group, lipopolysaccharide (LPS) group, LPS+ 50 &mgr;g/mL APS group, LPS+ 100 &mgr;g/mL APS group, LPS+ 200 &mgr;g/mL APS group, and LPS+ 500 &mgr;g/mL APS group. Levels of mRNAs in LPS-induced inflammatory factors, tumor necrosis factor (TNF)-α and interleukin (IL)-8, were measured by reverse transcription-polymerase chain reaction. MAPK protein level was measured by Western blotting.
RESULTS: The levels of TNF-α and IL-8 mRNAs were significantly higher in IEC with LPS-induced damage than in control cells. APS significantly abrogated the LPS-induced expression of the TNF-α and IL-8 genes. APS did not block the activation of extracellular signal-regulated kinase or c Jun amino-terminal kinase, but inhibited the activation of p38, suggesting that APS inhibits LPS-induced production of TNF-α and IL-8 mRNAs, possibly by suppressing the p38 signaling pathway.
CONCLUSION: APS-modulated bacterial product-mediated p38 signaling represents an attractive strategy for prevention and treatment of intestinal inflammation.

Abstract
Although Astragali Radix (Astragalus, AR), the root of Astragalus membranaceus (Fisch) Bunge, is widely used in oriental medicine for tonifying the immune response and improving circulation, the underlying mechanism(s) by which these effects are induced remains unclear. Here, we report that AR displays anti-inflammatory effects in zymosan air-pouch mice by reducing the expression of iNOS, COX-2, IL-6, IL-1beta and TNF-alpha and by decreasing the production of nitric oxide (NO). In a similar manner, AR reduces the expression of IL-6, iNOS, and COX-2 in lipopolysaccharide (LPS)-treated Raw 264.7 cells. We further demonstrate that AR attenuates the activity of p38 and Erk1/2 and stimulates mitogen-activated protein kinase phosphatase-1 (MKP-1) in LPS-treated Raw 264.7 cells. Additionally, AR interferes with the translocation of NFkappaB to the nucleus, subsequently resulting in NFkappaB-dependent transcriptional repression. Taken together, these data reveal that AR has an anti-inflammatory effect that is mediated by the MKP-1-dependent inactivation of p38 and Erk1/2 and inhibition of NFkappaB-mediated transcription. These results imply that the AR herb has a potential anti-inflammatory activity.

Abstract
BACKGROUND The prevalence of chronic renal disease exceeds 10% in industrialized societies. Oxidative damage is thought to be one of the main mechanisms involved in nearly all chronic renal pathologies. OBJECTIVE We aimed to use the oxygen radical absorbance capacity (ORAC) method and a sequential multisolvent extraction process to compare the in vitro antioxidant capacity of 55 medicinal herbs and prioritize them for in vivo studies investigating the value of herbal therapies in the treatment of renal disorders. METHODS The herbs were chosen on the basis of their traditional use in kidney or urinary system disorders, or because they have attracted the attention of recent investigations into renal pathologies. The three solvents used for extraction were ethyl acetate, methanol, and 50% aqueous methanol. Silybum marianum (milk thistle) seed and Camellia sinensis (tea) leaf, both known to possess high antioxidant capacity, were included for comparison. RESULTS Twelve of the 55 herbs were comparable to or exceeded ORAC levels of milk thistle seed or tea leaf. The highest radical-scavenging activity was found in Olea europaea (olive leaf), Cimicifuga racemosa (black cohosh), Rheum palmatum (rhubarb), Glycyrrhiza glabra (licorice), and Scutellaria lateriflora (Virginia skullcap). CONCLUSIONS The antioxidant capacity of many of the herbs studied may, at least in part, be responsible for their reputation as being protective of organs of the urinary system. Overall, the combined ORAC values for the methanol and aqueous methanol extracts comprised 84% of the total ORAC value. Sequential extraction with solvents of different polarities may be necessary to fully extract the antioxidant principles from medicinal plants.

Abstract
The results of several recent studies indicated that free radicals are involved in the biochemical mechanisms that underlie neuropsychiatric disorders. In the present study, we evaluated changes in oxidative stress and human 8-hydroxyguanine glycosylase1 gene (hOGG1) expression in depressive patients with acute leukemia. Ninety two cases were assessed using the Zung self-rating depression scale (SDS) and multiple-item questionnaires. We measured total antioxidant capacity (T-AOC) and the concentrations of reactive oxygen species (ROS), superoxide dismutase (SOD), malondialdehyde (MDA) and nitric oxide (NO) during a pre-treatment period. The steady-state expression of hOGG1 mRNA transcripts was monitored. The incidence of depression was 47.83%. There was a significant decrease in serum T-AOC and SOD concentrations in depressive patients compared to the control subjects, whereas the opposite was the case for serum concentrations of ROS, NO and MDA. Real-time polymerase chain reaction (PCR) revealed that hOGG1 mRNA expression was greater in depressive patients than in the controls. Person correlation analysis revealed that depression was correlated positively with sex, the course of the disease and hOGG1 mRNA expression; depression was correlated negatively with T-AOC. Based on these results, we conclude that the antioxidant system is impaired in leukemic patients with affective disorders. Therefore, oxidative stress may play an important role in the pathophysiology of depression.

Abstract
Extracorporeal shock-wave lithotripsy (ESWL)-induced renal damage can occur as a result of multiple mechanisms, including small vessel injury and free radical formation. Our previous studies have demonstrated that Astragalus membranaceus (AM), a traditional Chinese herb, could significantly alleviate shock wave-induced renal oxidative injury, and its renoprotective effects were superior to those of varapamil, a calcium antagonist, which were considered to be a powerful agent in treating renal damage during ESWL. However, the effective antioxidant ingredient of this herb in the setting of lithotripsy remains unclear. Astragalosides, the major components of AM, was demonstrated to have superior antioxidation properties both in vitro and in vivo. Therefore, in this study we further investigate the potential effects of astragalosides on the shock wave-induced oxidative stress in rabbit kidney. Thirty male rabbits were randomly assigned to two groups, each consisting of 15 rabbits: (1) control group, (2) astragaloside-treated group. Each group of animals underwent 1,500 shock waves to the right kidney. Peripheral blood, urine and kidney tissue samples were collected pre- and post-ESWL. The level of urinary N-acetyl-beta-glucosaminidase (NAG), serum creatinine, serum or homogenates malondialdehyde (MDA) and superoxide dismutase (SOD), respectively, were detected. Histological alterations were also examined through light microcopy and transmission electron microscopy. In the control group, shock wave significantly increased the level of MDA and decreased SOD activity in both blood and renal homogenates (P<0.05, respectively). The comparison between the control and astragalosides group demonstrated that astragalosides could significantly decrease the level of MDA (P<0.05) and inhibit the decline of SOD activity (P<0.05). After exposure to shock waves, the activity of urinary NAG increased significantly in the control group (P<0.05). However, the concentration of serum creatinine did not change significantly. The comparison between the control and astragalosides group demonstrated that astragalosides significantly reduced the shock wave-induced leakage of NAG into the urine (P<0.05). Histological examination also showed that renal morphological impairments were much milder in astragaloside-treated rabbits than those of the control group. Our results indicated that astragaloside treatment provided significant protection against shock wave-induced renal oxidative injury.

Abstract
PURPOSE OF REVIEW This review aims to cover the methods and techniques currently used by researchers to evaluate intestinal trophism. RECENT FINDINGS Although subjected to criticisms, conventional gut trophism evaluation by both morphological and histological parameters continues to be largely reported. The metaphase arrest technique and the detection of H-tymidine have been used less frequently in recent years due to increasing interest in the immunohistochemical methods such as 5-bromo-2'deoxy-uridine, Ki-67, and proliferating cell nuclear antigen. Along with common techniques for the evaluation of intestinal trophism, the combination of methods that includes a measurement of cell proliferation and an apoptotic index in the same study are most valuable and are increasing in the current literature. SUMMARY Evaluation of intestinal trophism is an important issue for both clinical and experimental nutritional studies. The immunohistochemical techniques are the gold standard to access cell proliferation. Evaluation of proliferation and apoptosis at the same time may offer a more reliable evaluation of the actual status of gut trophism.
