Abstract
[Formula: see text]-coumaric acid ([Formula: see text]-CA) is a common compound found in medicinal herbs, including Bambusae Caulis in Taeniam (BC). It has been used to treat various diseases in China and Korea. Our previous study demonstrated that BC inhibits pulmonary and intestinal inflammation. In the present study, we used cigarette smoke (CS) to induce lung inflammation in vivo, and investigated the anti-inflammatory effects of [Formula: see text]-CA on CS-induced inflammatory mice model. Mice were treated with BC and [Formula: see text]-CA via oral injection 2[Formula: see text]h before CS exposure. The body weight and the inflammatory cells in the bronchoalveolar lavage fluid were measured. The levels of relative inflammatory factors were confirmed by enzyme-linked immunosorbent assay. The lung histological changes were examined by hematoxylin and eosin staining. Also, the protein level of nuclear factor-[Formula: see text]B (NF-[Formula: see text]B) was evaluated by Western blotting. Our results indicated that BC and [Formula: see text]-CA inhibited CS-induced lung inflammation by regulating pro-inflammatory productions such as cytokines, chemokine, protease and NF-[Formula: see text]B. Consequently, these data demonstrated that [Formula: see text]-CA inhibited pulmonary inflammation by suppressing NF-[Formula: see text]B activity, through which pro-inflammatory mediators were regulated. Therefore, [Formula: see text]-CA, which was shown to be a major component of BC, can be considered as a strong therapeutic candidate for treating pulmonary inflammatory diseases.

PHARMACEUTICAL BIOLOGY 2017; 55:1561-1568. [PMID: 28385108 PMCID: PMC6130499 DOI: 10.1080/13880209.2017.1310905] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/31/2016] [Revised: 03/19/2017] [Accepted: 03/21/2017] [Indexed: 05/07/2023]
Abstract
CONTEXT To find bioactive medicinal herbs exerting anti-asthmatic activity, we investigated the effect of an aqueous extract of Urtica dioica L. (Urticaceae) leaves (UD), the closest extract to the Algerian traditional use. OBJECTIVE In this study, we investigated the in vivo anti-asthmatic and antioxidant activities of nettle extract. MATERIALS AND METHODS Adult male Wistar rats were divided into four groups: Group I: negative control; group II: Ovalbumin sensitized/challenged rats (positive control); group III: received UD extract (1.5 g/kg/day) orally along the experimental protocol; group IV: received UD extract (1.5 g/kg/day) orally along the experimental protocol and sensitized/challenged with ovalbumin. After 25 days, blood and tissue samples were collected for haematological and histopathological analysis, respectively. The oxidative stress parameters were evaluated in the lungs, liver and erythrocytes. Then, correlations between markers of airway inflammation and markers of oxidative stress were explored. RESULTS UD extract significantly (p < 0.01) inhibited eosinophilia increases in BALF (-60%) and the levels of leucocytes (-32.75%) and lymphocytes (-29.22%) in serum, and effectively suppressed inflammatory cells recruitment in the asthmatic rat model. Besides, the lipid peroxidation generated by allergen administration was significantly (p < 0.05) diminished by UD treatment in lung tissue (-48.58%). The nettle extract was also investigated for the total phenolic content (30.79 ± 0.96 mg gallic acid/g dry extract) and shows DPPH radical scavenging activity with 152.34 ± 0.37 μg/mL IC50 value. CONCLUSIONS The results confirmed that UD administration might be responsible for the protective effects of this extract against airway inflammation.

Abstract
Many studies have been done to evaluate the effect of various natural products in controlling asthma symptoms. Virgin coconut oil (VCO) is known to contain active compounds that have beneficial effects on human health and diseases. The objective of this study was to evaluate the effect of VCO inhalation on airway remodelling in a rabbit model of allergic asthma. The effects of VCO inhalation on infiltration of airway inflammatory cells, airway structures, goblet cell hyperplasia, and cell proliferation following ovalbumin induction were evaluated. Allergic asthma was induced by a combination of ovalbumin and alum injection and/or followed by ovalbumin inhalation. The effect of VCO inhalation was then evaluated via the rescue or the preventive route. Percentage of inflammatory cells infiltration, thickness of epithelium and mucosa regions, and the numbers of goblet and proliferative cells were reduced in the rescue group but not in preventive group. Analysis using a gas chromatography-mass spectrometry found that lauric acid and capric acid were among the most abundant fatty acids present in the sample. Significant improvement was observed in rescue route in alleviating the asthma symptoms, which indicates the VCO was able to relieve asthma-related symptoms more than preventing the onset of asthma.

Abstract
The pulmonary and intestinal systems have several characteristics in common. It is believed that these similarities somehow function to cause pulmonary-intestinal crosstalk during inflammation. Many studies have shown that pulmonary disease occurs in association with inflammatory bowel disease more often than is commonly recognized. Bambusae Caulis in Taeniam, a medicinal herb originated from the inner bark of Phyllostachys nigra var. henosis (Milford) Rendle (Poaceae), has been used to cure fever, diarrhea, and chest inflammation in Korea as well as in China. Cigarette smoke is a well-known risk factor for several inflammatory disorders. In this study, we induced pulmonary and bowel inflammation in mice using cigarette smoke and investigated whether Bambusae Caulis in Taeniam extract modulates the inflammatory response in both the lung and the bowel. C57BL/6 mice were exposed to cigarette smoke for 90 min per day for three weeks, and Bambusae Caulis in Taeniam extract was administered via oral injection 2 h before cigarette smoke exposure. The bronchoalveolar lavage cells were counted and hematoxylin and eosin staining were performed. Levels of inflammatory mediators in lung and large intestine were determined by enzyme-linked immunosorbent assay, real-time polymerase chain reaction, and Western blotting. Our results showed that Bambusae Caulis in Taeniam attenuated cigarette smoke-induced inflammatory response in both the lung and the bowel of mice by inhibiting the production of pro-inflammatory cytokines, chemokines, and protease as well as NF-κB signaling factor. Therefore, we suggest that Bambusae Caulis in Taeniam extract might be a candidate therapeutic agent for inhibiting pulmonary and intestinal inflammation.

Sceptridium ternatum attenuates allergic contact dermatitis-like skin lesions by inhibiting T helper 2-type immune responses and inflammatory responses in a mouse model. J Dermatol Sci 2015; 79:288-97. [PMID: 26150208 DOI: 10.1016/j.jdermsci.2015.06.012] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2015] [Revised: 05/19/2015] [Accepted: 06/23/2015] [Indexed: 12/18/2022]
Abstract
BACKGROUND Sceptridium ternatum (ST) is a medicinal herb used in folk remedies for the treatment of various disorders such as pertussis, allergic asthma, abdominalgia, diarrhea, and external use for wound healing. However, the biological and pharmacological activities of ST are not fully clarified besides anti-asthmatic effect. OBJECTIVE We studied a Sceptridium ternatum ethanol extract (ST) with respect to its anti-inflammatory and immune regulatory activities in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells, concanavalin A (conA)-stimulated BALB/c mice splenocytes, and a 2,4-dinitrochlorobenzene (DNCB)-induced allergic contact dermatitis (ACD) mouse model. METHODS RAW 264.7 cells were pretreated with ST for 1h and then stimulated with LPS. To determine the anti-inflammatory effects of ST, the production of nitric oxide (NO), interleukin (IL)-1β, IL-6, and tumor necrosis factor-α (TNF-α) were measured using an enzyme-linked immunosorbent assay (ELISA). To determine its anti-allergic effects, splenocytes from BALB/c mice were incubated and stimulated with conA in the absence or presence of ST for 48h. The production of IL-4 and interferon (IFN)-γ in culture supernatants were evaluated by ELISA. To test the effects of ST on ACD, 100μL of 1% DNCB was applied to the dorsal skin of BALB/c mice for 2 weeks, and ST was administered 2 h before DNCB application. The thicknesses of the epidermis and dermis were determined by skin histological analysis. Serum immunoglobulin (Ig) E levels, the production of IL-1β, IL-4, and IL-6 in dorsal skin tissue, and T helper (Th) 2 cytokines production of CD4(+) T cells were analyzed by ELISA. The expression of nuclear transcription factor-κB (NF-κB) both in vitro and in vivo was determined via immunoblotting. RESULTS In RAW 264.7 cells, ST inhibited LPS-induced inflammation mediator production and NF-κB expression. ST upregulated IFN-γ production and downregulated IL-4 production in conA-stimulated splenocytes. ST application reduced the thicknesses of the epidermis and dermis by decreasing serum IgE level and the expressions of IL-1β, IL-4, IL-6, and NF-κB in the dorsal skin of the DNCB-induced ACD model mice. Furthermore, ST treated group showed reduction of the Th2 cytokines production in activated CD4(+) T cells. CONCLUSION These findings not only indicate that application of ST reduced skin thickening by regulating Th 2-type allergic responses and inhibiting expression of inflammatory mediators in a DNCB-induced ACD mouse model, but also suggest that Sceptridium ternatum is a natural option for the treatment of skin inflammation.

Abstract
Zingiber mioga (Thunb.) Roscoe (ZM) is a traditional medicine, used to treat inflammatory diseases. The present study aimed to evaluate the inhibitory effects of ZM on the inflammatory response in lipopolysaccharide (LPS)‑stimulated RAW264.7 murine macrophage cells and in a mouse model of ovalbumin (OVA)‑induced allergic asthma. Mice received OVA sensitization on day 0 and 14, and were challenged with OVA between days 21 and 23. ZM was administered to the mice at a dose of 30 mg/kg, 1 h prior to OVA challenge. In LPS‑stimulated RAW264.7 cells, ZM significantly decreased nitric oxide (NO) and tumor necrosis factor (TNF)‑α production in a concentration‑dependent manner, and mRNA expression of inducible NO synthase (iNOS), TNF‑α and matrix metalloproteinase (MMP)‑9 was reduced. In addition, treatment with ZM decreased the inflammatory cell count in bronchoalveolar lavage fluid from the mice, and reduced the expression of interleukin (IL)‑4, IL‑5, IL‑13, eotaxin and immunoglobulin E. ZM also reduced airway hyperresponsiveness in OVA‑challenged mice, and attenuated the infiltration of inflammatory cells and mucus production in the airways, with a decrease in the expression of iNOS and MMP‑9 in lung tissue. In conclusion, the results of the present study indicate that ZM effectively inhibits inflammatory responses. Therefore, it may be that ZM has potential as a therapeutic agent for use in inflammatory diseases.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Stemona tuberosa (ST) is a traditional herbal medicine used for the treatment of various respiratory diseases in eastern Asia. AIM OF THE STUDY We investigated the anti-inflammatory effects of a ST water extract in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages and in cigarette smoke (CS)-induced lung inflammation mouse models. MATERIALS AND METHODS RAW 264.7 macrophages were treated with the ST extract and stimulated by LPS. The expressions of pro-inflammatory mediators were evaluated by using nitric oxide (NO) assay, enzyme-linked immunosorbent assay and Western blot analysis. After the C57BL/6 mice were exposed to CS, they were administrated with the ST extract. The accumulated inflammatory cells in the bronchoalveolar lavage fluid (BALF) were counted. Also, real-time polymerase chain reaction and hematoxylin and eosin staining were performed in lung tissues. RESULTS The ST extract treatment reduced the production of NO via blocking the expressions of cyclooxygenase-2 and inducible nitric oxide synthase protein in RAW 264.7 macrophages. In addition, ST extract treatment decreased the secretions of inflammatory cytokines and regulated NF-κB activation by inhibiting the phosphorylation of IκB and the mitogen-activated protein kinase pathway. Also, ST extract administration to mice reduced the infiltrations of macrophages into BALF and the histological inflammatory changes in lung tissues. Furthermore, administration of the ST extract regulated the levels of tumor necrosis factor-α, interleukin (IL)-6, IL-1β, monocyte chemoattractant protein-1 and matrix metalloproteinases-12 in the lungs. CONCLUSION These findings suggested that ST extract attenuated pulmonary inflammatory responses by inhibiting the expression of diverse inflammatory mediators in vivo and in vitro.

Abstract
Picrasma quassioides (D.Don) Benn. (PQ) is used in traditional medicine for the treatment of inflammatory conditions, including gastritis. This study aimed to evaluate the inhibitory effects of PQ on the inflammatory responses in mice with allergic asthma induced by ovalbumin (OVA) and in lipopolysaccharide (LPS)‑stimulated RAW264.7 cells. To induce allergic asthma, the mice underwent OVA sensitization on days 0 and 14 and then were challenged with OVA from days 21‑23. The mice were administered 15 and 30 mg/kg doses of PQ 1 h prior to the OVA challenge. The PQ treatment decreased the inflammatory cell count in the bronchoalveolar lavage fluid of the mice and reduced the levels of interleukin (IL)‑4, IL‑5, IL‑13 and immunoglobulin (Ig)E when compared with those in the OVA group. The PQ treatment also reduced the airway hyperresponsiveness induced by the OVA challenge, attenuated the recruitment of inflammatory cells and the mucus production in the airways of the mice. In the LPS‑stimulated RAW264.7 cells, the PQ treatment reduced the overexpression of inducible nitric oxide synthase (iNOS). The results indicated that PQ inhibits inflammatory responses in mice with OVA‑sensitized/challenged allergic asthma and in LPS‑stimulated RAW264.7 cells. These effects were considered to be associated with the suppression of iNOS expression. Therefore, PQ may have the potential to treat airway inflammatory diseases, including allergic asthma.

Abstract
Bamboo shavings (Bambusae Caulis in Taeniam, BCT) are widely used as a traditional Chinese medicine to control hypertension and cardiovascular disease, and to alleviate fever, vomiting, and diarrhea. It has been demonstrated that BCT reduces ovalbumin-induced airway inflammation by regulating pro-inflammatory cytokines, and decreases tumor growth in tumor-bearing mice. However, the effects of BCT on the metastatic potential of malignant cancer cells and the detailed mechanism of its anti-metastatic activity have not been examined previously. In this study, we investigated whether an aqueous extract of BCT (AE-BCT) reduces the metastatic potential of HT1080 cells, and elucidated the underlying anti-metastatic mechanism. In addition, we examined whether AE-BCT administration inhibits pulmonary metastasis of intravenously injected B16F10 cells in C57BL/6J mice. AE-BCT (50–250 µg/ml) dose-dependently suppressed colony-forming activity under anchorage-dependent and -independent growth conditions. Pretreatment with AE-BCT efficiently inhibited cell migration, invasion, and adhesion. AE-BCT also dramatically suppressed PMA-induced MMP-9 activity and expression by blocking NF-κB activation and ERK phosphorylation. Production of intracellular ROS, a key regulator of NF-κB-induced MMP-9 activity, was almost completely blocked by pretreatment with AE-BCT. Furthermore, daily oral administration of AE-BCT at doses of 50 and 100 mg/kg efficiently inhibited lung metastasis of B16F10 cells injected into the tail veins of C57BL/6J mice with no systemic toxicity. These results demonstrate that AE-BCT significantly reduced the metastatic activity of highly malignant cancer cells by suppressing MMP-9 activity via inhibition of ROS-mediated NF-κB activation. These results indicate that AE-BCT may be a safe natural product for treatment of metastatic cancer.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lilium lancifolium Thunb. (Liliaceae) has long been used as a traditional medicine in Korea and China to treat bronchitis, pneumonia, and other pulmonary ailments. AIM OF THE STUDY Cigarette smoke (CS) is a major risk factor for the development of pulmonary inflammatory response; it also triggers pulmonary alveoli enlargement. In the present study, we investigate the effects of Lilium lancifolium Thunb. root extract on pulmonary inflammatory responses in a CS-exposed mouse model. MATERIALS AND METHODS Water extract of Lilium lancifolium Thunb. root was fed to C57BL/6 mice prior CS exposure every day for 3 weeks. The numbers of macrophages and neutrophils in bronchoalveolar lavage fluid (BALF) were counted. The relative inflammatory factors, tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), interleukin-1 beta (IL-1β), monocyte chemotactic protein-1 (MCP-1), and matrix metalloproteinase-12 (MMP-12) were measured by real-time PCR, ELISA, or Western blot analysis. The average alveoli size was determined by lung histology. RESULTS Lilium lancifolium Thunb. root extract was found to significantly inhibit the numbers of macrophages and neutrophils in BALF due to CS exposure. Lilium lancifolium Thunb. root extract also reduced the protein secretion levels of TNF-α, IL-6, IL-1β, and MCP-1 in BALF and the RNA expression levels of TNF-α, IL-6, IL-1β, MCP-1, and MMP-12 in lung tissue compared with mice only exposed to CS. Moreover, MMP-12 in serum was down regulated in Lilium lancifolium Thunb. root extract treated mice compared with CS-exposed mice. Finally, a morphometric analysis of the lungs of Lilium lancifolium Thunb. root extract treated mice demonstrated a significant reduction in airspace size compared to mice only exposed to CS. CONCLUSION Our results show that Lilium lancifolium Thunb. root extract reduces lung inflammation and airspace enlargement in a CS-exposed mouse model. These data indicate that Lilium lancifolium Thunb. root extract is a therapeutic candidate for pulmonary inflammation and emphysema caused by CS.

Abstract
Vitex rotundifolia L. (VR) as long been used in China and Korea in traditional medicine. This study was conducted to evaluate the ability of Vitex rotundifolia L. to prevent airway inflammation and remodeling in an ovalbumin (OVA)-induced murine asthma model. The total cell number and number of inflammatory cells in the bronchoalveolar lavage (BAL) fluid were counted. The levels of cytokines in the BAL fluid and serum IgE levels were measured using an ELISA. For histological analysis, hematoxylin and eosin staining, periodic acid-Schiff staining and immunohistochemistry were evaluated. The release of total cells into the BAL fluid was significantly inhibited in OVA-induced asthmatic mice treated with VR extract. In addition, eosinophilia and lymphocytosis were reduced significantly in mice that received VR extract. Furthermore, levels of the T(h)2 cytokines IL-4 and IL-5 and pro-inflammatory cytokine TNF-α in the BAL fluid and total IgE in serum were markedly suppressed by VR extract. OVA-specific IgE in the serum and IL-13 in the BAL fluid were decreased, but not significantly. The allergic effects of VR extract were accompanied by a reduction in airway hyperresponsiveness. Additionally, morphologic findings demonstrated that VR extract substantially inhibited OVA-induced eosinophilia, goblet cell hyperplasia and smooth muscle mass production. This finding suggests that VR extract may have pharmacological effects that would be useful for the treatment of asthma via the inhibition of the T(h)2 response and airway remodeling.

Abstract
Recently, it has been reported that several natural extracts have anti-inflammatory effects through HO-1 induction. In this study, we used the ethyl acetate fraction of Bambusae Caulis in Taeniam (BCE) to investigate its anti-inflammatory effect on macrophages stimulated with LPS from Porphyromonas gingivalis. BCE inhibited the production of pro-inflammatory cytokines in P. gingivalis LPS-stimulated RAW264.7 cells. BCE also suppressed the nuclear translocation of NF-κB and AP-1. A selective inhibitor of HO-1 attenuated BCE's inhibitory effects on the production of pro-inflammatory cytokines. BCE also dose-dependently increased HO-1 expression at both the mRNA and the protein levels. BCE increased nuclear translocation of Nrf-2. Finally, a specific inhibitor of p38 reduced BCE-induced HO-1 expression and BCE-induced phosphorylation of p38 MAPK. BCE induced anti-inflammatory effects by activating Nrf-2-mediated HO-1 induction via p38 signaling in P. gingivalis LPS-stimulated macrophages. This result indicates that BCE is a promising therapeutic agent for combating periodontitis.

Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory joint disease associated with matrix metalloproteinase (MMP)-3, leading to destruction of the cartilage. The objective of this study was to investigate and discuss the suitability of the 35 medicinal plants as therapeutic candidates to treat RA. Fibroblast-like synoviocytes (FLSs), derived from patients with RA, were adjusted to 2 × 10(6) cells/mL in a 24-well plate and pretreated with the distilled water extracts of the 35 plants (1, 10, and 100 µg/mL) for 1 h followed by interleukin-1β (IL-1β) (1 ng/mL) for 24 h. The concentration of MMP-3 was then determined using a Duoset ELISA Kit. The six plants (Artemisiae Capillaris Herba, AC; Bambusae Caulis In Taeniam, BC; Cassiae Semen, CS; Corni Fructus, CF; Leonuri Herba, LH; Schizonepetae Spica, SS) showed no toxicity, including MMP-3. The MMP-3 level was increased by 3.38-fold (212.23 μg/mL) in IL-1β-stimulated FLSs. The IL-1β-induced MMP-3 level was significantly and dose-dependently reduced by >50% by the six plants (P < 0.01: at 100 μg/ mL of CS and LH, P < 0.001: at 10 μg/mL of all plants, and at 100 μg/mL of AC, BC, CF, and SS). This is the first study on the MMP-3 inhibitory effect of the examined plants in FLSs isolated from RA patients. From our original research, the six candidate plants were identified.

Anti-inflammatory, immunomodulatory, and heme oxygenase-1 inhibitory activities of ravan napas, a formulation of uighur traditional medicine, in a rat model of allergic asthma. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2010; 2011. [PMID: 20953388 PMCID: PMC2952321 DOI: 10.1155/2011/725926] [Citation(s) in RCA: 26] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/09/2010] [Revised: 07/01/2010] [Accepted: 08/13/2010] [Indexed: 12/13/2022]
Abstract
Ravan Napas (RN) is a traditional formula used to treat pulmonary symptoms and diseases such as coughing, breathing difficulty, and asthma in traditional Uighur medicine. The purpose of this study was to investigate the anti-inflammatory, and immuno-modulatory activity of RN in a well-characterized animal model of allergic asthma. Rats were sensitized with intraperitoneal (ip) ovalbumin (OVA) and alum, and then challenged with OVA aerosols. The asthma model rats were treated with RN; saline- and dexamethasone- (DXM-) treated rats served as normal and model controls. The bronchoalveolar lavage fluid (BALF) cellular differential and the concentrations of sICAM-1, IL-4, IL-5, TNF-α, INF-γ, and IgE in serum were measured. Lung sections underwent histological analysis. The immunohistochemistry S-P method was used to measure the expression of ICAM-1 and HO-1 in the lung. RN significantly reduced the number of inflammatory cells in BALF and lung tissues, decreased sICAM-1, IL-4, IL-5, TNF-α, and IgE in serum, and increased serum INF-γ. There was a marked suppression of ICAM-1 and HO-1 expression in the lung. Our results suggest that RN may have an anti-inflammatory and immuneregulatory effect on allergic bronchial asthma by modulating the balance between Th1/Th2 cytokines.
