Abstract
The aim of our review is to demonstrate the potential of herbal preparations, specifically adaptogens for prevention and treatment of respiratory infections, as well as convalescence, specifically through supporting a challenged immune system, increasing resistance to viral infection, inhibiting severe inflammatory progression, and driving effective recovery. The evidence from pre-clinical and clinical studies with Andrographis paniculata, Eleutherococcus senticosus, Glycyrrhiza spp., Panax spp., Rhodiola rosea, Schisandra chinensis, Withania somnifera, their combination products and melatonin suggests that adaptogens can be useful in prophylaxis and treatment of viral infections at all stages of progression of inflammation as well as in aiding recovery of the organism by (i) modulating innate and adaptive immunity, (ii) anti-inflammatory activity, (iii) detoxification and repair of oxidative stress-induced damage in compromised cells, (iv) direct antiviral effects of inhibiting viral docking or replication, and (v) improving quality of life during convalescence.

Abstract
Nobiletin (NOB), the major bioactive component of polymethoxyflavones in citrus fruits, has been reported possessing significant biological properties. The purpose of the present study was to investigate the protective role of NOB on lipopolysaccharide (LPS)-induced endotoxic shock in mice. We found pretreatment with NOB increases the survival rate of mice after endotoxin injection. The present study clearly demonstrates that pretreatment with NOB decreases the production of early pro-inflammatory cytokines TNF-α, IL-6, and late-phase mediator HMGB1 in serum and tissues of kidney, lung, and liver. The histopathological study indicates that NOB administration significantly attenuate tissues injury induced by LPS. Moreover, NOB suppresses the activity of nuclear factor-kappa B (NF-κB). These results suggest that NOB protects mice against LPS-induced endotoxic shock through inhibiting the production of TNF-α, IL-6, and HMGB1 and the activation of NF-κB, which elucidate that NOB may be a promising drug candidate for the treatment of septic shock.

Abstract
BackgroundDespite great advancement in treatment of sepsis, mortality of sepsis remains unacceptably high, even with the modern antibiotic and intensive care technologies. Considering the key role of immune dysfunction in sepsis pathophysiology, different treatments were evaluated, but failed to improve survival of patients. Natural remedies have been tested in various studies to overcome sepsis. In this study, we aim to review some of the evidence from clinical, in vitro and in vivo studies about the effect of alternative medicine on sepsis management. MethodsThe following databases were searched up to March 2014: PubMed, Scopus, Web of Science, Ovid and Google Scholar using combination of Mesh term. All in vitro and in vivo studies, also clinical trials, published in English, which evaluated alternative medicine in management of sepsis were included. Results Out of 95 relevant studies, the inclusion criteria were met for 79 cases. Among them, 18 studies were performed on humans. The most herbal medicine, including Xubijing (n=10) and then Rhubarb (n=3). Most of the reviewed botanical medicines modulate the immune system. Reduction of mortality was also reported in studies. ConclusionsModulation of immune system, anti-inflammatory activities and improvement of survival were the action of herbal medicine. A monovalent approach is not enough for treatment of sepsis, we recommend further studies to identify active component of herbal and use them in combination. Also an animal model of sepsis does not exactly mimic human sepsis, so more clinical studies should be performed. With no new drug on the horizon, herbal medicine will be promising for treatment of sepsis.

Abstract
The antioxidant activity and chlorogenic acid and caffeic acid contents were investigated from different parts of Acanthopanax senticosus and A. koreanum. Antioxidant activity was assessed by various in vitro assays such as DPPH, ABTS, FRAP, reducing power assays and ORAC, and the chlorogenic acid and caffeic acid were validated by HPLC chromatography. Among the various extracts, the fruit extracts of A. senticosus and A. koreanum exhibited strongest antioxidant activities including ABTS, FRAP, reducing power and ORAC, however, strongest DPPH radical scavenging activity was observed from the leaf extract of A. senticosus. In addition, the antioxidant activities of various extracts were correlated with total phenolic and proanthocyanidin contents. The major phenolic contents from various parts of these plants observed that leaf extract of A. senticosus expressed higher levels of chlorogenic acid (14.86 mg/dry weigh g) and caffeic acid (3.09 mg/dry weigh g) than other parts. Therefore, these results suggest that the leaf of A. senticosus may be an excellent natural source for functional foods and pharmaceutical agents, and the validated method was useful for the quality control of A. senticosus.

JOURNAL OF ETHNOPHARMACOLOGY 2014; 158 Pt A:331-337. [PMID: 25446641 DOI: 10.1016/j.jep.2014.10.032] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/17/2014] [Revised: 06/13/2014] [Accepted: 10/19/2014] [Indexed: 06/04/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Scirpus yagara Ohwi is a perennial, aquatic plant, whose dry tubers have long been used as Traditional Chinese Medicine (TCM) "Sanleng" for the treatment of postpartum abdominal pain, hyperemesis gravidarum, amenorrhea, dyspepsia and several inflammatory related diseases. Although it is known to have anti-inflammatory activities, its mechanism of action on lipopolysaccharide (LPS)-induced inflammation has not yet been identified in detail.This study was designed to investigate the anti-inflammatory activity of the active fraction (AF) from the tuber of Scirpusyagara both in vitro and in vivo. MATERIALS AND METHODS RAW264.7 macrophage was incubated for 16h with 1µg/ml of LPS in absence or presence of AF (0, 10, 50 and 100µg/ml) and the secretions of tumor necrosis-alpha (TNF-α) and interleukin-6 (IL-6) in the medium were determined by using an enzyme-linked immunosorbent assay (ELISA). In the in vivo study, mice were orally administrated with AF (50 and 300mg/kg) for three days consecutively. 1h after the last AF administration, the mice were intraperitoneally injected with LPS (15mg/kg), and the life span of LPS-challenged mice were determined. Furthermore, the levels of pro-inflammatory cytokines TNF-α and IL-6 in the serum, lung and liver were measured using ELISA kit, and histological change in lungs was examined by light microscopy. Additionally, the components of AF were analyzed by high performance liquid chromatography (HPLC) using a C18 column. RESULTS AF significantly decreased TNF-α and IL-6 production induced by LPS in RAW264.7 macrophage. In LPS-induced mouse endotoxin shock model, AF pre-treatment significantly improved the survival rate of mice. And LPS-induced increases of pro-inflammatory cytokines TNF-α and IL-6 in the serum, lung and liver were markedly suppressed by AF. Moreover, the histopathological examination indicated that AF could significantly attenuate lung tissues injury in endotoxemic mice. In addition, eight compounds (protocatechuic acid, vanillic acid, p-coumaric acid, ferulic acid, methyl-3,6-dihydroxy-2-[2-(2-hydroxyphenyl)-ethynyl] benzoate, sciryagarol I, sparstolonin B, SanLeng diphenyllactone) of AF were quantified by HPLC analysis. CONCLUSIONS These results suggested that AF protected mice against LPS-induced lethality by inhibiting the production of multiple cytokines and organ dysfunction. Thus AF may prove beneficial in the prevention and treatment of endotoxin shock.

Abstract
Increasing indication is unveiling a role for poly(ADP-ribose) polymerase (PARP)-1 in the regulation of inflammatory/immune responses. The aim of the present study was to determine the potential anti-inflammatory effects of PARP-1 inhibitor 5-aminoisoquinolinone (5-AIQ) to explore the role of PARP-1 inhibitor in a mouse model of carrageenan-induced lung inflammation. A single dose of 5-AIQ (1.5mg/kg) was administered intraperitoneally (i.p.) 1h before λ-carrageenan (Cg) administration. We assessed the effects of 5-AIQ treatment on CD25(+), GITR(+), CD25(+)GITR(+), IL-17(+) and Foxp3(+) cells which were investigated using flowcytometry in pleural exudates and heparinized blood. We also evaluated mRNA expressions of IL-6, TNF-α, IL-1β, IL-10, CD11a, l-selectin (CD62L), ICAM-1, MCP-1, iNOS and COX-2 in the lung tissue. We further examined the effects of 5-AIQ on the key mediators of inflammation, namely COX-2, STAT-3, NF-kB p65, PARP-1, IkB-α and IL-4 protein expression in the lung tissue using western blotting. The results illustrated that the numbers of T cell subsets, IL-17(+) cytokine levels were markedly increased and Foxp3(+) production decreased in the Cg group. Furthermore, Cg-induced up-regulation of adhesion molecules, pro-inflammatory mediators and chemokine expressions. Western blot analysis revealed an increased protein expressions of COX-2, STAT-3 NF-kB p65 and PARP-1 and decreased IkB-α and IL-4 in the Cg group. PARP-1 inhibitor via 5-AIQ treatment reverses the action significantly of all the previously mentioned effects. Moreover, histological examinations revealed anti-inflammatory effects of 5-AIQ, whereas Cg-group aggravated Cg-induced inflammation. Present findings demonstrate the potent anti-inflammatory action of the PARP-1 inhibitor in acute lung injury induced by carrageenan.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Acanthopanax senticosus, classified into the family of Araliaceae, has been known for thousands of years as a remedy and is used to treat various diseases in traditional Chinese medicine system including hypertension, ischemic heart disease and hepatitis. AIM OF THE STUDY This study aimed to examine the protective effects of aqueous extract from Acanthopanax senticosus (ASE) on corticosterone-induced neurotoxicity and its possible mechanisms, using PC12 cells as a suitable in vitro model of depression. MATERIALS AND METHODS In this paper, PC12 cells were treated with 200 μM of corticosterone in the absence or presence of ASE in varying concentrations for 24 h. Then, cell viability was measured by MTT assay. The release amount of lactate dehydrogenase (LDH) was quantified using LDH assay kit. Apoptosis of PC12 cells was measured by Annexin V-FITC and PI labeling. The intracellular Ca(2+) content was tested by fluorescent labeling. The mRNA level of brain-derived neurotrophic factor (BDNF) was examined by real-time RT-PCR, and the expression of cAMP response element binding protein (CREB) was determined by western blotting. RESULTS The results showed that treatment with 200 μM of corticosterone could induce cytotoxicity in PC12 cells. However, different concentrations of ASE (50, 100, 200, and 400 μg/mL) significantly increased the cell viability, decreased the LDH release, suppressed the apoptosis of PC12 cells, attenuated the intracellular Ca(2+) overloading, up-regulated the BDNF mRNA level and CREB protein expression compared with the corresponding corticosterone-treated group. CONCLUSION The present results suggest that ASE exerts a neuroprotective effect on corticosterone-induced neurotoxicity in PC12 cells, which may be one of the acting mechanisms that accounts for the in vivo antidepressant activity of ASE.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Aanthopanax senticosus (A. senticosus) Harms is a classical adaptogenic agent used in China. It has been applied as an analeptic aid to improve weakened physical status. However, little is known about the effects of A. senticosus on inflammatory disease processes. MATERIALS AND METHODS Flies fed with standard cornmeal-yeast medium were used as controls, and the treatment groups contained 10% of A. senticosus aqueous extracts (root or fruit) in standard medium. Survival rate was performed by feeding a vial containing five layers of filter paper hydrated with 5% sucrose solution contaminated with pathogenic or toxic compounds. Imaging of the guts was viewed under the microscope. Death cells were detected by 7-AAD staining. RESULTS The A. senticosus extract improved the survival rate, attenuated the death of intestinal epithelial cells, promoted the expression of antimicrobial peptide genes, and decreased the formation of melanotic masses. Moreover, our results indicated that the protective effect of fruit is much higher than that of root extracts. CONCLUSIONS A. senticosus extracts have a protective effect on Drosophila gut immunity and stress response, and may contribute to the prevention of inflammatory diseases induced by pathogenic and toxic compounds.

Abstract
Extracts of Acanthopanax senticosus, a traditional herb commonly found in Northeastern Asia, are used for treating neurodegenerative disorders such as ischemia and depression. However, the mechanisms of its neuroinflammatory and cytoprotective effects have not been investigated. We examined the mechanism of A. senticosus activity in anti-neuroinflammatory and neuroprotective processes. HO-1 is an inducible enzyme present in most cell lines. ASE increased HO-1 expression, which reduced LPS-induced nitric oxide/ROS production in BV2 cells. Moreover, the induction of HO-1 expression protected cells against glutamate-induced neuronal cell death. Activation of the p38-CREB pathway and translocation of Nrf2 are strongly involved in ASE-induced HO-1 expression. Our results showed that ASE-induced HO-1 expression through the p38-CREB pathway plays an important role in the generation of anti-neuroinflammatory and neuroprotective responses. ASE also increases the translocation of Nrf2 to regulate HO-1 expression. Furthermore, our results indicate that ASE serves as a potential therapeutic agent for neuronal disorders.

Abstract
Isofraxidin (IF) is a Coumarin compound that can be isolated from medicinal plants, such as Sarcandra glabra (Thunb.). Nakai is widely used in Asian countries for the treatment of anti-bacterial, anti-inflammatory and anti-tumour action. The present investigation was designed to evaluate the effect of IF on inflammation and nociception. In addition, we investigated a potential novel mechanism to explain the anti-inflammatory properties of IF. In vivo, xylene-induced mouse ear edema, carrageenan-induced rat paw edema, LPS-induced mouse endotoxic shock, acetic acid-induced mice writhing and formalin-induced mouse pain models were used to evaluate the anti-inflammatory activity of IF. In vitro, we examined the effects of IF inhibition on TNF-α production and the regulation of ERK1/2 and p38 phosphorylation activity in LPS-induced mouse peritoneal macrophages. Our results demonstrated that IF can significantly decrease xylene-induced ear edema, carrageenan-induced paw edema, acetic acid-induced writhing and formalin-induced pain. Moreover, IF greatly inhibited the production of TNF-α in the serum of LPS-stimulated mice and peritoneal macrophages, and it decreased phospho-p38 and ERK1/2 protein expression in LPS-stimulated mouse peritoneal macrophages. Overall, our data suggest that IF possesses significant analgesic and anti-inflammatory activities that may be mediated through the regulation of pro-inflammatory cytokines, TNF-α and the phosphorylation of p38 and ERK1/2.

Abstract
In the present study, we investigated the anti-fatigue activity in male Kunming mice of extracts of stem bark from Acanthopanax senticosus (ASSE) using a forced swimming test. Mice were divided into four groups (three ASSE administered groups and the control group). The control group were gavaged with distilled water and ASSE administered groups were gavaged with ASSE (100, 200 and 400 mg/kg). After four weeks, a forced swimming test was performed and the biochemical parameters related to fatigue were examined. The results suggested that ASSE could extend the swimming time to exhaustion of the mice, as well as increase the tissue glycogen contents, while decreasing the blood lactate and serum urea nitrogen contents. This indicated that ASSE had anti-fatigue activity and could elevate the exercise tolerance.
