Abstract
Cordyceps militaris (C. militaris) has various biomedical applications in traditional oriental medicine for different diseases including inflammatory and immune-dysregulated diseases. It is a reservoir of nutritional components such as cordycepin, polysaccharides, and antioxidants. To improve its bioactivity, we fermented C. militaris with a Pediococcus pentosaceus strain isolated from a salted small octopus (SC11). The current study aimed to evaluate whether P. pentosaceus (SC11) fermentation could enhance the anti-allergic potential of C. militaris cultured on germinated Rhynchosia nulubilis (GRC) against a type I hypersensitive reaction in in vitro and in vivo studies. Total antioxidant capacity and cordycepin content were significantly increased in GRC after SC11 fermentation. GRC-SC11 showed significantly enhanced anti-allergic responses by inhibiting immunoglobulin E (IgE)/antigen-induced degranulation in RBL-2H3 cells, compared to GRC. The results demonstrated the significant inhibition of phosphorylated spleen tyrosine kinase (Syk)/ p38/GRB2-associated binding protein 2 (Gab2)/c-jun in IgE/Ag-triggered RBL-2H3 cells. Furthermore, suppressed mRNA levels of interleukin-4 (IL-4) and tumor necrosis factor-α (TNF-α) in IgE/Ag-activated RBL-2H3 cells were observed. GRC-SC11 significantly ameliorated IgE-induced allergic reactions by suppressing the ear swelling, vascular permeability, and inflammatory cell infiltration in passive cutaneous anaphylaxis (PCA) BALB/c mice. In conclusion, GRC fermented with P.pentosaceus exerted enhanced anti-allergic effects, and increased the cordycepin content and antioxidants potential compared to GRC. It can be used as bio-functional food in the prevention and management of type I allergic diseases.

Abstract
Mast cell activation syndrome is thought to be a common, yet under-recognized, chronic multi-system disorder caused by inappropriate mast cell activation. Gastrointestinal symptoms are frequently reported by these patients and are often mistaken by physicians as functional gastrointestinal disorders. This syndrome can be diagnosed by the medical history and measurable biomarkers. Gastroenterologists manage diseases associated with active inflammatory cells including neutrophils, lymphocytes, macrophages, and eosinophils. The mast cell has only recently been recognized as a major player in our specialty. Gastrointestinal disorders from mast cell mediators often present with apparent irritable bowel syndrome, dyspepsia, chronic or cyclical nausea, and heartburn. Individuals with mast cell activation syndrome experience significant delays in diagnosis. The gastrointestinal symptoms are often refractory to symptom-targeted prescription medications. Beyond avoiding triggers, the best therapy is directed at modulating mast cell activation and the effects of the mediators. Many of these therapies are simple over-the-counter medications. In this article, we review mast cell function and dysfunction and the gastrointestinal symptoms, comorbid conditions, diagnosis, and management of mast cell activation syndrome. Gastroenterologists who become aware of this syndrome can dramatically improve the quality of life for their patients who previously have been labeled with a functional gastrointestinal disorder.

Abstract
INTRODUCTION Activation of mast cells causes alteration in epithelial and neuromuscular function, and is involved in visceral hypersensitivity and dysmotility in gastrointestinal functional disorders. OBJECTIVES Primary: Evaluate differences in basal serum tryptase (BST) between patients with irritable bowel syndrome (IBS) and healthy controls. Secondary: BST depending on IBS subtype (diarrhea: IBS-D; constipation: IBS-C), comorbidities and correlations with IBS severity and quality of life. MATERIAL AND METHODS Prospective control-case study in IBS patients (Rome IV criteria). BST was determined (ImmunoCAP-Phadia, Sweden®) IBS Severity Score (IBSSS), pain, bloating and flatulence analogue scales, IBS quality of life (IBSQOL) and patient health status (PHQ-9) were performed. BST is the primary variable in achieving the primary end-point. RESULTS Thirty-two patients, 21 (65.6%) IBS-D, 11 (34.4%) IBS-C and 32 controls were included. Mean IBSSSS: 326.6 (± 71.4), IBSQOL: 76 (± 20.3) and PHQ9: 10.2 (± 5.9). BST was 4.8 ± 2.6 in IBS and 4.7± 2.6 in controls (p=0.875). There was no difference in BST between IBS subtypes (4.7 ± 2.9 in IBS-D and 5± 1.8 in IBS-C; p =0.315) or IBS severity (p=0.662). However, BST was higher in patients with IBS and extraintestinal comorbidities compared to other patients and controls (p=0.029). This subgroup also has more severe bloating (p=0.021). There was no correlation between BST, quality of life (p=0.9260) and health status (p=0.3985). CONCLUSION BST does not discriminate between IBS patients and controls. However, BST was higher in patients with IBS with extraintestinal comorbidities which have more severe bloating. This finding is worthy of investigation.

Fundam Clin Pharmacol 2020; 34:433-443. [PMID: 31967341 DOI: 10.1111/fcp.12537] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2019] [Revised: 12/23/2019] [Accepted: 01/08/2020] [Indexed: 12/12/2022]
Abstract
Visceral hypersensitivity (VH) is common in irritable bowel syndrome (IBS), and female patients are more likely to seek healthcare services for IBS-related abdominal pain. Oestrogen has been reported to mediate pain modulation via its receptor, and mast cells are known to participate in the development of visceral hypersensitivity. Our previous studies showed that the G-protein-coupled oestrogen receptor (GPER, also known as GPR30) was expressed by mast cells in human colonic tissues and was associated with IBS type and severity of visceral pain. However, whether GPER is involved in oestrogen-dependent visceral hypersensitivity via mast cell degranulation is still unknown. Rats were subjected to wrap partial restraint stress to induce visceral hypersensitivity and were ovariectomized (OVX) to eliminate the effects of oestrogen on visceral hypersensitivity. OVX rats were treated with oestrogen, an oestrogen receptor α and β antagonist (ICI 182.780), a GPER antagonist (G15) or a GPER agonist (G1), to evaluate the effects of oestrogen via its receptor. The colorectal distention test was performed to assess visceral sensitivity. Immunofluorescence studies were performed to evaluate GPER and mast cell tryptase co-expression. Mast cell number with degranulation was detected by specific staining. Mast cell tryptase expression in rat colon was also investigated by Western blot and immunohistochemistry. Substance P and histamine expression were examined by ELISA. GPER was expressed by the majority of tryptase-positive mast cells in the colonic mucosa. Stressed rats showed increased visceral sensitivity, increased mast cell degranulation, mast cell tryptase expression, and increased colon histamine levels. Ovariectomy reduced stress-induced VH in female rats and decreased mast cell degranulation, mast cell tryptase expression, and histamine levels, whereas oestrogen replacement reversed these effects. In OVX rats, the GPER antagonist G15 counteracted the enhancing effects of oestrogen on stress-induced VH, mast cell degranulation, mast cell tryptase, and histamine expression, whereas VH was preserved after treatment with ICI 182.780. On the other hand, pretreatment with the selective GPER agonist G1 at doses between 1 and 20 μg/kg significantly increased VH, mast cell tryptase, and histamine expression in OVX-stressed rats, mimicking the effects of oestrogen. GPER plays a pivotal role in the regulation of mast cell degranulation, mast cell tryptase expression, and histamine levels and contributes to the development of colonic hypersensitivity in a female rat model of IBS.

Traditional Tibetan medicine Anzhijinhua San attenuates ovalbumin-induced diarrhea by regulating the serotonin signaling system in mice. JOURNAL OF ETHNOPHARMACOLOGY 2019; 236:484-494. [PMID: 30738115 DOI: 10.1016/j.jep.2019.01.020] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/05/2018] [Revised: 11/02/2018] [Accepted: 01/24/2019] [Indexed: 06/09/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tibetan medicine has been practiced for 3800 years. Anzhijinhua San (AZJHS), which is a traditional Tibetan medicine, has been effective in the treatment of indigestion, anorexia and cold diarrhea. However, the effects of AZJHS on allergic diarrhea have not been reported. AIM OF THE STUDY The aim of the present study was to elucidate the effect of AZJHS on experimental ovalbumin-induced diarrhea and elucidate its possible mechanism. MATERIALS AND METHODS Female BALB/c mice were sensitized by intraperitoneal injection with 50 μg ovalbumin (OVA) and 1 mg alum in saline twice during a 2-week period. From day 28, mice were orally challenged with OVA (50 mg) every other day for a total of ten times. AZJHS (46.8 and 468.0 mg/kg) was orally administered every other day from day 0-46. Food allergy symptoms were evaluated. OVA- specific IgE, 5-HT and its metabolites in serum were determined. Immunohistochemical and histopathology were performed in gastrointestinal tract tissues. 5-HT-related gene expression was assayed in the colon. RESULTS Severe symptoms of allergic diarrhea were observed in the model group (diarrhea, anaphylactic response, and rectal temperature). AZJHS (46.8 and 468.0 mg/kg) significantly reduced mouse diarrhea and significantly prevented the increases in OVA-specific IgE levels (P < 0.05), which challenge with OVA. AZJHS (46.8 and 468.0 mg/kg) significantly prevented the increases in 5-HT-positive cells. The nuclei of EC cells in the AZJHS (46.8 and 468.0 mg/kg) group increased in size and the secretory granules were fewer in number compared with those in the model group. AZJHS (46.8 and 468.0 mg/kg) significantly increased the relative fold changes of 5-HTP and 5-HT compared with the model group. The mRNA expression of the serotonin transporter (Sert) and serotonin receptor 3A (Htr3a) was significantly decreased after the 10th challenge with OVA, and AZJHS (46.8 and 468.0 mg/kg) significantly increased these levels. CONCLUSIONS We demonstrated that the administration of AZJHS attenuated OVA-induced diarrhea by regulating the serotonin pathway. These results indicated that AZJHS may be a potential candidate as an anti-allergic diarrhea agent.

Abstract
This study is to investigate the effects of imperatorin (IMP) on allergic responses mediated by mast cells, both in vitro and in vivo. Passive cutaneous anaphylaxis (PCA) model was established. Histological detection was performed to assess the ear histology. ELISA and Western blot analysis were used to detect the levels of corresponding cytokines and signalling pathway proteins. IMP decreased the leakage of Evans blue and the ear thickness in the PCA models, in a dose-dependent manner, and alleviated the degranulation of mast cells. Moreover, IMP reduced the expression of TNF-α, IL-4, IL-1β, IL-8, and IL-13. Furthermore, IMP inhibited the phosphorylation levels of Syk, Lyn, PLC-γ1, and Gab2, as well as the downstream MAPK, PI3K/AKT, and NF-κB signaling pathways. In addition, IMP inhibited the mast cell-mediated allergic responses through the Nrf2/HO-1 pathway. IMP attenuates the allergic responses through inhibiting the degranulation and decreasing the expression levels of proinflammatory cytokines in the mast cells, involving the PI3K/Akt, MAPK, NF-κB, and Nrf2/HO-1 pathways.

Abstract
Epiploic appendagitis is as an acute painful condition of the fat on the outside of the intestine. Thus far, there have been no publications to our knowledge that appendagitis can be caused by mast cells or can be associated with chronic pain. A patient with multisystemic disorders suffered with both chronic and acute attacks of abdominal pain for a year. The worst attack led to surgical resection of an enlarged sigmoid colon epiploic appendage. Careful review of her complex medical history and mast cell stains of gastrointestinal biopsies led to the diagnosis of mast cell activation syndrome. Re-examination of the resected appendage using an immunohistochemical stain demonstrated a high mast cell density which is a new histopathological finding. Treatment of mast cell activation syndrome and other related syndromes led to marked improvement in her health, including all types of chronic abdominal pain.

Abstract
Polydatin(PD) shows anti-allergic inflammatory effect, and this study investigated its underlying mechanisms in in vitro and in vivo models. IgE-mediated passive cutaneous anaphylaxis (PCA) and passive systemic anaphylaxis (PSA) models were used to confirm PD effect in vivo. Various signaling pathway proteins in mast cell were examined. RT-PCR, ELISA and western blotting were applied when appropriate. Activity of Lyn and Fyn kinases in vitro was measured using the Kinase Enzyme System. PD dose-dependently reduced the pigmentation of Evans blue in the PCA model and decreased the concentration of serum histamine in PSA model, and attenuated the degranulation of mast cells without generating cytotoxicity. PD decreased pro-inflammatory cytokine expression (TNF-α, IL-4, IL-1β, and IL-8). PD directly inhibited activity of Lyn and Syk kinases and down-regulated downstream signaling pathway including MAPK, PI3K/AKT and NF-kB. In addition, PD also targets Nrf2/HO-1 pathway to inhibit mast cell-derived allergic inflammatory reactions. In conclusion, the study demonstrates that PD is a possible therapeutic candidate for allergic inflammatory diseases. It directly inhibited activity of Lyn and Syk kinases and down-regulates the signaling pathway of MAPK, PI3K/AKT and NF-κB, and up-regulates the signaling pathway of Nrf2/HO-1 to inhibit the degranulation of mast cells.

Abstract
PURPOSE To evaluate wound contraction and the concentration of mast cells in skin wounds treated with wild plum (Ximenia americana) essential oil-based ointment in rats. METHODS Sixty rats were submitted to two cutaneous wounds in the thoracic region, on the right and left antimeres. Thereon, they were divided into three groups: GX (wounds treated once a day with hydro alcoholic branch extract of Ximenia americana), GP (wounds that received vehicle), and GC (wounds without product application). Wounds were measured immediately after the injury as well as 4, 7, 14 and 21 days post-topical application of the extract. At these days, five rats from each group were euthanatized. Thereafter, samples were fixed in 10% formaldehyde and processed for paraffin embedding. Sections were stained with H.E, Masson's Trichrome and toluidine blue for morphological, morphometrical and histopathological analysis, under light microscopy. The degree of epithelial contraction was measured and mast cell concentrations were also evaluated with an image analyzer (Image Pro-plus®software) . RESULTS The extract treated group showed lower mast cell concentrations in the 4th day of lesion, as compared to GP (GX<GP=GC, p=0.029), as well as with increased contraction at 7th and 14th days, respectively (7th and 14th days, GX > GP = GC; p<0.05) . CONCLUSION Ointment containing 10% X. americana induces a decrease in mast cell concentration, at the beginning of the healing process, and promotes early skin wound contraction in rats.
