Platycodin D stimulates AMPK activity to inhibit the neurodegeneration caused by reactive oxygen species-induced inflammation and apoptosis. JOURNAL OF ETHNOPHARMACOLOGY 2023; 308:116294. [PMID: 36804201 DOI: 10.1016/j.jep.2023.116294] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 02/06/2023] [Accepted: 02/15/2023] [Indexed: 06/18/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Alzheimer's disease (AD) was considered to be a neurodegenerative disease that caused cognitive impairment. Reactive Oxidative stress (ROS) was considered to be one of a major cause of the onset and progression of AD. Platycodin D (PD), a representative saponin from Platycodon grandiflorum, has conspicuous antioxidant activity. However, whether PD could protect nerve cell against oxidative injury remains unknown. AIM OF STUDY This study investigated the regulatory effects of PD on neurodegeneration caused by ROS. To determine whether PD could play its own antioxidant role in neuronal protection. MATERIALS AND METHODS First, PD(2.5, 5 mg/kg) ameliorated the memory impairment induced by AlCl3 (100 mg/kg) combined with D-galactose (D-Gal) (200 mg/kg) in mice, using the radial arm maze (RAM) test, and neuronal apoptosis in the hippocampus was evaluated by hematoxylin and eosin staining (HE). Next, the effects of PD (0.5, 1, and 2 μM) on okadaic-acid (OA) (40 nM) -induced apoptosis and inflammation of HT22 cells were investigated. Mitochondrial ROS production was measured by fluorescence staining. The potential signaling pathways were identified through Gene Ontology enrichment analysis. The role of PD in regulating AMP-activated protein kinase (AMPK) was assessed using siRNA silencing of genes and an ROS inhibitor. RESULTS In vivo, PD improved memory in mice, and recovered the morphological changes of brain tissue and nissl bodies. In vitro experiment, PD increased cell viability (p < 0.01; p < 0.05;p < 0.001), decreased apoptosis (p < 0.01), reduced excessive ROS and MDA, rised SOD and CAT content(p < 0.01; p < 0.05). Morover, it can block the inflammatory response caused by ROS. Be important, PD strengthen antioxidant ability by elevating AMPK activation both in vivo and in vitro. Furthermore, molecular docking suggested a good likelihood of PD-AMPK binding. CONCLUSION AMPK activity is vital for the neuroprotective effect of PD, suggesting that PD may be a potential pharmaceutical agent to treat ROS-induced neurodegeneration.

Abstract
Coronavirus disease 2019 (COVID-19) is a worldwide health threat that has long-term effects on the patients and there is currently no efficient cure prescribed for the treatment and the prolonging effects. Traditional Chinese medicines (TCMs) have been reported to exert therapeutic effect against COVID-19. In this study, the therapeutic effects of Jing Si herbal tea (JSHT) against COVID-19 infection and associated long-term effects were evaluated in different in vitro and in vivo models. The anti-inflammatory effects of JSHT were studied in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells and in Omicron pseudotyped virus-induced acute lung injury model. The effect of JSHT on cellular stress was determined in HK-2 proximal tubular cells and H9c2 cardiomyoblasts. The therapeutic benefits of JSHT on anhedonia and depression symptoms associated with long COVID were evaluated in mice models for unpredictable chronic mild stress (UCMS). JSHT inhibited the NF-ƙB activities, and significantly reduced LPS-induced expression of TNFα, COX-2, NLRP3 inflammasome, and HMGB1. JSHT was also found to significantly suppress the production of NO by reducing iNOS expression in LPS-stimulated RAW 264.7 cells. Further, the protective effects of JSHT on lung tissue were confirmed based on mitigation of lung injury, repression in TMRRSS2 and HMGB-1 expression and reduction of cytokine storm in the Omicron pseudotyped virus-induced acute lung injury model. JSHT treatment in UCMS models also relieved chronic stress and combated depression symptoms. The results therefore show that JSHT attenuates the cytokine storm by repressing NF-κB cascades and provides the protective functions against symptoms associated with long COVID-19 infection.

Anti-inflammatory effect and metabolic mechanism of BS012, a mixture of Asarum sieboldii, Platycodon grandiflorum, and Cinnamomum cassia extracts, on atopic dermatitis in vivo and in vitro. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 115:154818. [PMID: 37187105 DOI: 10.1016/j.phymed.2023.154818] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Revised: 02/23/2023] [Accepted: 04/10/2023] [Indexed: 05/17/2023]
Abstract
BACKGROUND Atopic dermatitis (AD) is a chronic, relapsing skin disease accompanied by itchy and dry skin. AD is caused by complex interactions between innate and adaptive immune response. AD treatment include glucocorticoids and immunosuppressants. However, long-term treatment can have serious side effects. Thus, an effective AD treatment with fewer side effects is required. Natural materials, including herbal medicines, have potential applications. PURPOSE This study evaluated the in vivo and in vitro therapeutic effects of BS012, a mixture of Asarum sieboldii, Platycodon grandiflorum, and Cinnamomum cassia extracts, on AD and investigated the underlying metabolic mechanisms. METHODS The anti-inflammatory effects of BS012 were assessed using a mouse model of AD induced by 1‑chloro-2,4-dinitrobenzene (DNCB) and in tumor necrosis factor-alpha/interferon-gamma (TNF-α/IFN-γ) stimulated normal human epidermal keratinocytes (NHEKs). In DNCB-induced mice, total dermatitis score, histopathological analysis, and immune cell factors were assessed to evaluate the anti-atopic activity. In TNF-α/IFN-γ-stimulated NHEKs, pro-inflammatory cytokines, chemokines, and related signaling pathways were investigated. Serum and intracellular metabolomics were performed to identify the metabolic mechanism underlying the therapeutic effects of BS012 treatment. RESULTS In DNCB-induced mice, BS012 showed potent anti-atopic activity, including reducing AD-like skin lesions and inhibiting the expression of Th2 cytokines and thymic stromal lymphopoietin. In TNF-α/IFN-γ-stimulated keratinocytes, BS012 dose-dependently inhibited the expression of pro-inflammatory cytokines and chemokines by blocking nuclear factor-kappa B and signal transducer and activator of transcription signaling pathways. Serum metabolic profiles of mice revealed significant changes in lipid metabolism related to inflammation in AD. Intracellular metabolome analysis revealed that BS012 treatment affected the metabolism associated with inflammation, skin barrier function, and lipid organization of the stratum corneum. CONCLUSION BS012 exerts anti-atopic activity by reducing the Th2-specific inflammatory response and improving skin barrier function in AD in vivo and in vitro. These effects are mainly related to the inhibition of inflammation and recovery of metabolic imbalance in lipid organization. BS012, a novel combination with strong activity in suppressing the Th2-immune response, could be a potential alternative for AD treatment. Furthermore, the metabolic mechanism in vivo and in vitro using a metabolomics approach will provide crucial information for the development of natural products for AD treatment.

Abstract
Platycodon grandiflorus (Jacq.) A. DC. (PG) root is one of the most commonly used medicine-food materials for respiratory discomfort in Asia, usually in the form of a decoction or leaching solution. As everyone knows, both of decoction and leaching solution is a polyphase dispersion system, containing low-molecular-weight water-soluble active ingredients and hydrophilic macromolecules. This study aimed to discuss the synergistic effect of Platycodon grandiflorus polysaccharide (PGP) and platycodin D (PD) in PG decoction against chronic bronchitis (CB) and the mechanism underlying. A series of PGP, PD, and PGD + PD suspensions were administrated to CB model rats, on the levels of whole animal and in situ intestinal segment with or without mesenteric lymphatic vessels ligation. It exhibited that PGP exhibited synergistic effects with PD, on improving the histopathological abnormity, mucus secretion excess, and immunological imbalance in lung of CB model rat, closely associated with its modulations on the mucosal immunity status in small intestine. The polysaccharide macromolecules in PG decoction or leaching solution should be responsible for the modulation of pulmonary immune state, possibly through the common mucosal immune between small intestine and lung. These results might be a new perspective that illustrates the classical theory of “the lung and intestine are related” in traditional Chinese medicine.

Abstract
The edible and medicinal plants (EMPs) are becoming an abundant source for cancer prevention and treatment since the natural and healthy trend for modern human beings. Currently, there are more than one hundred species of EMPs widely used and listed by the national health commission of China, and most of them indicate immune or metabolic regulation potential in cancer treatment with numerous studies over the past two decades. In the present review, we focused on the metabolic influence in immunocytes and tumor microenvironment, including immune response, immunosuppressive factors and cancer cells, discussing the immunometabolic potential of EMPs in cancer treatment. There are more than five hundred references collected and analyzed through retrieving pharmacological studies deposited in PubMed by medical subject headings and the corresponding names derived from pharmacopoeia of China as a sole criterion. Finally, the immunometabolism modulation of EMPs was sketch out implying an immunometabolic control in cancer treatment.

Abstract
Atopic dermatitis (AD) is considered a great challenge for human communities and imposes both physiological and mental burdens on patients. Natural products have widely been used to treat a wide range of diseases, including cancer, gastrointestinal diseases, asthma, neurological disorders, and infections. To seek potential natural products against AD, in the current review, we searched the terms "atopic dermatitis" and "natural product" in Pubmed, Medline, Web of Science,Science Direct, Embase, EBSCO, CINAHL, ACS. The results show that many natural products, especially puerarin, ferulic acid and ginsenosides, cound protect against AD. Meanwhile, we discussed the therapeutic mechanisms and showed that the natural products exert their anti-inflammatory effects by suppressing the quantity and activity of many inflammatory cell types and cytokines, including neutrophils, monocytes, lymphocytes, Langerhans cells, interleukins (ILs, including IL-1α, IL-1β, IL-4), TNF-α, and TSLP, IgE. via inhibition of JAK/STAT, MAPKs and NF-κB signaling pathways, thereby, halting the inflammatory cascade. Future investigations should focus on studies with more reflective of the clinical characteristics and demographics, so as to develop natural products that will be hopefully available for the treatment of human AD disease.

Abstract
Atopic dermatitis (AD) is the long-lasting chronic inflammatory skin condition associated with cutaneous hyper-reactivity and triggered by environmental factors. The attributes of AD include dry skin, pruritus, lichenification and frequent eczematous abrasions. This has a strong heritable aspect and typically occurs with asthma and allergic rhinitis. The complex pathological mechanism behind AD etiology is epidermal barrier destruction resulting in the lack of filaggrin protein that can induce inflammation and T-cell infiltration. T-helper 2 cell-mediated pathways also bear the responsibility of damage to the epidermal barrier. Certain causative factors for AD include microbial imbalance of skin microbiota, immunoglobulin-E-induced sensitization and neuro-inflammation. Numerous beneficial topical and oral treatments have been available to patients and there are even more drugs in the pipeline for the treatment of AD. Topical moisturizers, corticosteroids, anti-inflammatory agents such as calcineurin inhibitors, phototherapy, cAMP-specific 3, 5 half-cyclic phosphodiesterase 4 inhibitors and systemic immunosuppressants are widely available for AD treatments. Different positions and pathways inside the immune system including JAK-STAT, phosphodiesterase 4, aryl hydrocarbon receptor and T-helper 2 cytokines are targeted by above-mentioned drug treatments. Instead of the severe side effects of topical steroids and oral antihistamines, herbal plants and their derived phytoconstituents are commonly used for the treatment of AD. A clear understanding of AD's cellular and molecular pathogenesis through substantial advancement in genetics, skin immunology and psychological factors resulted in advancement of AD management. Therefore, the review highlights the recent advancements in the understanding of clinical features, etiology, pathogenesis, treatment and management and non-adherence to AD treatment.

Abstract
Atopic Dermatitis (AD) is a prolonged reverting skin ailment with characteristically distributed
skin lesions. In the previous decades, researchers had shown a marked interest in AD due to
its increased prevalence in developed countries. Although different strategies including biological
and immune modulators are available for the treatment of AD, each has certain limitations. The
researchers had shown considerable interest in the management of AD with herbal medicines. The
establishment of herbal drugs for AD might eliminate local as well as systemic adverse effects associated
with long term use of corticosteroids and also higher cost of therapy with biological drugs.
The present review discusses the traditional East Asian herbal medicines and scientific data related
to newer herbal extracts or compositions for the treatment of AD. In vivo animal models and in
vitro cell cultures, investigated with herbal medicines to establish a possible role in AD treatment,
have also been discussed in the paper. The paper also highlights the role of certain new approaches,
i.e. pharmacopuncture, a combination of allopathic and herbal medicines; and novel carriers
(liposomes, cubosomes) for herbal drugs on atopic skin. In conclusion, herbal medicines can be a
better and safe, complementary and alternative treatment option for AD.

Introduction: Roots of Asparagus cochinchinensis, which have pharmacologically active ingredients, have received great attention because they show good therapeutic effects for various inflammatory diseases without specific toxicity. This study investigated the anti-asthmatic effects of a butanol extract of Asparagus cochinchinensis roots that had been fermented with Weissella cibaria (BAW) and its possible underlying cholinergic regulation. Methods: Alterations of the anti-asthmatic markers and the molecular response factors were measured in an ovalbumin (OVA)-induced asthma model after treatment with BAW. Results: Treatment with BAW decreased the intracellular reactive oxygen species (ROS) production in lipopolysaccharides (LPS) activated RAW264.7 cells. The results of the animal experiments revealed lower infiltration of inflammatory cells and bronchial thickness, and a significant reduction in the number of macrophages and eosinophils, concentration of OVA-specific IgE, and expression of Th2 cytokines in the OVA + BAW treated group. In addition, a significant recovery of goblet cell hyperplasia, MMP-9 expression, and the VEGF signaling pathway was observed upon airway remodeling in the OVA + BAW treated group. Furthermore, these responses of BAW were linked to recovery of acetylcholine esterase (AChE) activity and muscarinic acetylcholine receptor (mAChR) M3 downstream signaling pathway in epithelial cells, smooth muscle cells, and afferent sensory nerves of OVA + BAW-treated mice. Conclusion: Overall, these findings are the first to provide evidence that the therapeutic effects of BAW can prevent airway inflammation and remodeling through the recovery of cholinergic regulation in structural cells and inflammatory cells of the chronic asthma model.

Abstract
Acupuncture has shown beneficial effect in the treatment of multiple dermatologic conditions including dermatitis, pruritus, urticaria, and hyperhidrosis; however, the detailed mechanisms are still kept unclear. This study aimed to investigate if electro-acupuncture (EA) treatment prevents 2,4-dinitrofluorobenzene (DNFB)-induced allergic contact dermatitis (ACD) in rats and explore its underlying mechanisms. ACD was induced by sensitizing and challenging with DNFB topically. Rats were treated daily following bilateral subcutaneous stimulation of EA at Zusanli acupoint (ST36) for 1 week. Ear swelling and serum IgE levels were measured. The ear biopsies were obtained for histology. Inflammatory cytokines on the dermatological ear and local acupoint tissue were assayed. Spleen lymphocytes and the homogenized supernatant of local acupuncture area were used to co-culture for flow cytology and immune analysis, respectively. EA treatment at ST36 notably inhibited ear swelling and inflammatory cell infiltration on DNFB-induced ACD. EA also decreased serum IgE concentrations and alleviated the production of inflammatory cytokines in dermatological ear. Additionally, EA treatment attenuated the percentage of CD4+IFN-γ+ and CD4+IL-4+ T cells associated with ACD. Interestingly, secretion of interleukin (IL)-10 in the local acupoint tissue following EA stimulation was increased and showed suppressive function when co-cultured with the spleen lymphocytes from DNFB group. Lastly, EA treatment demonstrably suppressed p38 MAPK activation in DNFB-treated rats. Our findings suggest that EA treatment at ST36 may ameliorate inflammation associated with DNFB-induced ACD via triggering local IL-10 production and inhibiting p38 MAPK activation, which provide an alternative and promising therapy for ACD.

Abstract
The present study investigated the effect of Sargassum fulvellum ethanol extract (SFEE) on 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD)-like skin lesions in BALB/c mice. The severity of skin dermatitis, production of cytokines, and total IgE content were measured, and the histopathological features were analyzed. SFEE decreased the severity of DNCB-induced dermatitis and suppressed the serum levels of total immunoglobulin E (IgE), tumor necrosis factor (TNF)-α, and interleukin (IL)-4. In addition, SFEE reduced the production of IL-4, IL-5, and IL-13 in mice splenocytes. However, the levels of IL-10 and interferon (IFN)-γ significantly increased in mice sera and splenocytes. Histological examination revealed decreased dermal thickness and infiltration by mast cells after treatment with SFEE. Furthermore, grasshopper ketone, a compound isolated from SFEE, was found to significantly decrease cytokine production in concanavalin A-stimulated splenocytes from BALB/c mice with no cytotoxicity. Taken together, these results indicate that SFEE and the isolated grasshopper ketone have an inhibitory effect on AD by regulating immune mediators and cells and may be a potential effective alternative therapy for AD.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin disease with a complex etiology that encompasses immunologic responses. AD is frequently associated with elevated immunoglobulin (Ig) E levels, and common environmental factors contribute to its pathogenesis. Several recent studies have documented the role of specific lactic acid bacteria in the treatment and prevention of AD in humans and mice. In this study, the efficacy of Duolac ATP, a probiotic preparation, was determined in a mouse model with AD-like skin lesions. Alterations in the cytokine levels and histological staining suggested the alleviation of AD. The in vivo test showed that T helper (Th)2 cytokines, IgE, interleukin (IL)-4, and IL-5, were significantly downregulated, whereas Th1 cytokines, IL-12p40 and interferon (IFN)-γ, were upregulated in all groups of mice treated with Duolac ATP compared to that observed in the group of mice treated with 1-chloro-2,4-dinitrobenzene (DNCB) alone. Moreover, the scratch score decreased in all mice treated with Duolac ATP. Staining of the dorsal area of the mice in each group with hematoxylin and eosin and toluidine blue further confirmed the alleviation of AD in mice orally treated with Duolac ATP. These results suggest that Duolac ATP inhibits the development of AD-like skin lesions in NC/Nga mice by suppressing the Th2 cell response and increasing the Th1 cell response. Thus, Duolac ATP is beneficial and effective for the treatment of AD-like skin lesions.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin disease, with a complex etiology encompassing immunologic responses. AD is frequently associated with elevated serum immunoglobulin (Ig) E levels and is exacerbated by a variety of environmental factors, which contribute to its pathogenesis. However, the etiology of AD remains unknown. Recently, reports have documented the role of lactic acid bacteria (LAB) in the treatment and prevention of AD in humans and mice. The LAB, Lactobacillus casei (LC), is frequently used in the treatment of AD. To identify the active component of LC, we screened fractions obtained from the ion exchange chromatography of LC extracts. Using this approach, we identified the candidate protein, P14. We examined whether the P14 protein has anti-atopic properties, using both in vitro and in vivo models. Our results showed that the P14 protein selectively downregulated serum IgE and interleukin-4 cytokine levels, as well as the AD index and scratching score in AD-like NC/Nga mice. In addition, histological examination was also effective in mice. These results suggest that the P14 protein has potential therapeutic effects and that it may also serve as an effective immunomodulatory agent for treating patients with AD.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin disease, which requires safe and effective treatment. In this study, we evaluated the effects of SSC201, a herbal formulation consisting of Stemonae Radix, Spirodelae Herba, and Cnidii Fructus, on the development of AD induced by 2,4-dinitrochlorobenzene in the NC/Nga murine model. Oral administration of SSC201 significantly reduced the severity of dermatitis and the tendency of mice to scratch their lesions. SSC201 significantly reduced the thickening of the epidermis/dermis and the infiltration of T cells, eosinophils, and mast cells into the dermis. These results were supported by findings of reduced numbers of CD4(+), CCR3(+), and CD117(+)FcɛRIα(+) cells in the skin. Furthermore, SSC201 significantly decreased the number of CD4(+), CD8(+), and CD3(+)CD69(+) T cells in lymph nodes. SSC201 not only decreased the plasma levels of immunoglobulin E (IgE) and the numbers of IgE-producing B cells (B220(+)CD23(+)), but also reduced the number of eosinophils and the levels of eotaxin as well as concentrations of thymus and activation-regulated chemokine in the periphery. Splenic levels of Th2 cytokines, including interleukin (IL)-4, IL-5, and IL-13, were reduced, whereas the levels of IL-12, a Th1 cytokine, were increased. Taken together, our data suggest that SSC201 may be an effective therapeutic agent for the treatment of AD.

Abstract
Integrative medicine is a relatively new discipline which attempts to combine allopathic medicine with alternative or complementary medicine, to reap the benefits of both forms of medicine in optimizing the care of patients. Integrative medicine concentrates on treating the patient as a whole, both in body and mind. While the scientific method and "evidence-based" clinical research drives the management and treatment of diseases in conventional Western medicine, alternative or complementary medicine is based on unproven yet potentially beneficial techniques that have been developed throughout history, dating back to the ancient cultures in the Middle East, Africa, and China. In spite of the lack of evidence of most alternative medicine techniques, these methodologies have been practiced for centuries with great acceptance in many countries. It is in the Western world, where "modern" medicine is dictated by the scientific method, that the most controversy in the use of these alternative modes of therapy exists. Since the science behind alternative medicine is incomplete or non-existent, it is difficult for those trained in Western medicine to accept or adopt this approach. But perhaps it is the failure of Western medicine to adequately guarantee our well being and good health that have led to the ongoing debate between the medical profession and the general public as to the benefits of these alternative treatments. In one sense, integrative medicine may be a futile attempt to coin a new term in the hope of legitimizing alternative medicine. On the other hand, there is a wealth of historical experience in the use of the techniques. Studies to evaluate the scientific basis behind ancient medical techniques are ongoing, and it is to be expected that the results will neither be uniformly positive nor negative. Of particular interest is the effect of traditional medicine, herbal formulations, and manipulative techniques on the immune system, and its application in the treatment of autoimmune and allergic diseases. Studies are being designed or conducted to investigate immune effects of herbal formulations or their components. Herbal plants or medicines may lead to skewing of the Th1/Th2 balance in either direction, thus may offer potential application in the treatment of allergic or autoimmune diseases.

Abstract
Objective: To investigate the therapeutic effect of crude extract from Platycodon grandiflorum (PG) roots on atopic dermatitis (AD)-like skin lesions in NC/Nga mice. Materials and Methods: To develop atopic dermatitis-like lesions, 200 μl of 0.3% 1-chloro-2, 4-dinitro benzene (DNCB) in acetone/olive oil (3:1) was applied 3 times a week for 2 weeks on the shaved skin of their backs. PG extract was dissolved in saline and orally administrated at concentrations of 300 and 500 mg/kg every day for 2 weeks. The therapeutic effect of PG on AD-like skin lesions was assessed by measuring skin severity scores and epithermal thickness, serum total immunoglobulin (Ig) E, histopathological findings for inflammatory cells including mast cells, macrophage and T cells, and mRNA expression of various cytokines related to the inflammatory and allergic response. The significance of inter-group differences was analyzed using the ANOVA test. Data were considered to be significant when P < 0.05 or P < 0.01. Results: Oral treatment of PG suppressed AD-like skin lesions according to the assessment of skin severity and epithermal thickness in the DNCB-treated NC/Nga mice. This alleviation was further correlated with a reduction of elevated serum total IgE or cytokine mRNA in the PG-treated group compared with vehicle-treated positive group. In addition, infiltrated inflammatory cells decreased on the skin lesions compared with vehicle-treated group. Conclusion: These results suggest that PG may have a potential therapeutic effect for AD via the inhibition of both inflammatory and allergic reaction.

Abstract
The aim of the present study was to evaluate the protective effect of aqueous extract from Platycodon grandiflorum (BC703) on bile duct ligation (BDL)-induced hepatic fibrosis in rats. BDL rats were divided into three groups, which orally received distilled water or BC703 (10 or 50 mg/kg/day) for consecutive 28 days. Antifibrotic effects of BC703 on BDL-induced hepatic fibrosis in rats were estimated by assessing serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), blood urea nitrogen (BUN), transforming growth factor-beta 1 (TGF-β1) and hepatic levels of malondialdehyde (MDA), glutathione (GSH), total superoxide dismutase (SOD) and nitric oxide (NO). The biochemical observations were supplemented by histopathological examination of liver samples stained with hematoxylin and eosin and Masson’s trichrome stain. ALT, AST, TBIL and BUN were elevated in the group treated with BDL alone than in the sham-operated group. These elevations were significantly decreased by BC703 treatment. Hepatic GSH and SOD levels, depressed by BDL, were also increased in the BC703 group. In addition, increases in hepatic MDA and NO levels in the BDL-induced cholestasis were attenuated by BC703 treatment. Furthermore, BC703 treatment significantly reduced the serum level of fibrogenic cytokine, TGF-β1. Histopathological studies further substantiated the protective effect of BC703 on BDL-induced hepatic fibrosis in rat. BC703 may have beneficial effects not only on hepatic fibrosis by cholestasis but also on hepatic fibrosis development in patients with chronic hepatic disease.

Abstract
Atopic dermatitis (AD) is characterized as a multi-factorial inflammatory skin disease that has been increasing worldwide. Previously, we demonstrated that FPG, which is Platycodon grandiflorum (PG) fermented by Lactobacillus plantarum (LP), increases the level of interferon (IFN)-gamma in mouse splenocytes in vitro. In this study, we investigated the effects of FPG in an animal model of AD, with a particular emphasis on its effects on T helper (Th)1 and Th2 immune responses. To assess the potential use of FPG for the inhibition of AD, we established a model of AD-like skin lesions in NC/Nga mice. Immunoglobulin isotypes (Igs) and Th1/Th2 cytokines in the sera and spleens of AD-like mice were examined. In addition, histological examination was also performed. AD symptoms in skin lesions improved following oral administration of FPG. IgE secretion was significantly down-regulated, and this was accompanied by decreased levels of interleukin (IL)-4 and IgG1 and increased serum levels of IL-12p40 and IgG2a in FPG-treated animals. In splenocytes, the production of the Th1 cytokines IL-12p40 and IFN-gamma was up-regulated, while the levels of the Th2 cytokines IL-4 and 5 were down-regulated by FPG treatment. These results suggest that FPG inhibits the development of AD-like skin lesions in NC/Nga mice by suppressing the Th2 cell response and increasing the Th1 cell responses. Our results indicate that FPG is safe and effective for the prevention of AD-like skin lesions.

Abstract
Atopic dermatitis (AD) is a common inflammatory skin disease for which few effective treatments are available. Resolvin E1 (RvE1; 5S,12R,18R-trihydroxy-6Z,8E,10E,14Z,16E-eicosapentaenoic acid) is an endogenous lipid mediator derived from omega-3 fatty eicosapentaenoic acid, which is a potent inhibitor of inflammation. AD-like skin lesion was induced by repetitive skin contact with DNFB in NC/Nga mice and the effects of RvE1 were evaluated on the basis of histopathological findings of skin, ear swelling and cytokine production of CD4(+) T cells. Intraperitoneal injection of RvE1 for one week after DNFB challenge significantly lowered ear swelling and improved back skin lesions. In addition, RvE1 significantly suppressed production of interferon-gamma (IFN-γ) and interleukin-4 (IL-4) by activated CD4(+) T cells and serum IgE level. Furthermore, RvE1 reduced DNFB-induced infiltration of eosinophils, mast cells, CD4(+) T cells, and CD8(+) T cells in skin lesions. Therefore, RvE1 may suppress the development of AD-like skin lesions in DNFB-treated NC/Nga mice by reducing IL-4 and IFN-γ of activated CD4(+) T cells and serum IgE levels and infiltration of immune cells to skin lesion.

Abstract
Atopic dermatitis (AD) is a chronic, relapsing, and inflammatory skin disease associated with eczematous symptoms and IgE hyperproduction. Psidium guajava is an important food crop and medicinal plant with anti-oxidant, anti-inflammatory, and anti-allergic activities, supporting its traditional uses. Our previous studies have shown that P. guajava extract inhibits Th2 chemokine expression by suppressing the activation of NF-κB and STAT1 co-stimulated with TNF-α and INF-γ. In this study, we investigated the inhibitory effect of P. guajava water extract (PGW) on 2,4-dinitrochlorobenzene (DNCB)-induced AD-like skin lesions in NC/Nga mice. Treatment of cream containing PGW onto DNCB-induced AD-like skin lesions in NC/Nga mice ameliorated lesion intensity scores, levels of IgE, thymus and activation-regulated chemokine (TARC), TNF-α, and IL-4 in serum and ears. In contrast, PGW increased level of the immunosuppressive cytokine IL-10. Histological analyses demonstrated decreased thickening of the epidermis/dermis as well as dermal infiltration by inflammatory cells. These results suggest that cream containing PGW may be a potential therapeutic modality for AD and adjunctive agent to control pruritus in AD.
