Identification of anti-fibrotic and pro-apoptotic bioactive compounds from Ganoderma formosanum and their possible mechanisms in modulating TGF-ß1-induced lung fibrosis.

ETHNOPHARMACOLOGICAL RELEVANCE: The Compendium of Materia Medica and the Classic of Materia Medica, the two most prominent records of traditional Chinese medicine, documented the therapeutic benefits of Ganoderma sinense particularly in addressing pulmonary-related ailments. Ganoderma formosanum, an indigenous subspecies of G. sinense from Taiwan, has demonstrated the same therapeutic properties. AIM OF THE STUDY: The aim of this study is to identify bioactive compounds and evaluate the potential of G. formosanum extracts as a novel treatment to alleviate pulmonary fibrosis (PF). Using an in-house drug screening platform, two-stage screening was performed to determine their anti-fibrotic efficacy. METHODS AND MATERIALS: G. formosanum was fractionated into four partitions by solvents of different polarities. To determine their antifibrotic and pro-apoptotic properties, the fractions were analyzed using two TGF-ß1-induced pulmonary fibrosis cell models (NIH-3T3) and human pulmonary fibroblast cell lines, immunoblot, qRT-PCR, and annexin V assays. Subsequently, transcriptomic analysis was conducted to validate the findings and explore possible molecular pathways. The identification of potential bioactive compounds was achieved through UHPLC-MS/MS analysis, while molecular interaction study was investigated by multiple ligands docking and molecular dynamic simulations. RESULTS: The ethyl acetate fraction (EAF) extracted from G. formosanum demonstrated substantial anti-fibrotic and pro-apoptotic effects on TGF-ß1-induced fibrotic models. Moreover, the EAF exhibited no discernible cytotoxicity. Untargeted UHPLC-MS/MS analysis identified potential bioactive compounds in EAF, including stearic acid, palmitic acid, and pentadecanoic acid. Multiple ligands docking and molecular dynamic simulations further confirmed that those bioactive compounds possess the ability to inhibit TGF-ß receptor 1. CONCLUSION: Potential bioactive compounds in G. formosanum were successfully extracted and identified in the EAF, whose anti-fibrotic and pro-apoptotic properties could potentially modulate pulmonary fibrosis. This finding not only highlights the EAF's potential as a promising therapeutic candidate to treat pulmonary fibrosis, but it also elucidates how Ganoderma confers pulmonary health benefits as described in the ancient texts.

Impact of a Novel Homeopathic Complex Medicine on the Management of Multiple Antibiotic-Resistant Bovine Mastitis: An Open-Label, Non-Randomized, Placebo-Controlled Trial.

BACKGROUND: Bovine mastitis is characterized by an inflammatory process in the mammary gland and represents one of the main diseases affecting a dairy herd. Management of mastitis is most commonly via antibiotics, but the rising incidence of multiple antibiotic resistance (MAR) means that additional options are needed. Homeopathic products can be administered in dairy farming for a range of clinical reasons and may be preferential due to the absence of residues. OBJECTIVES: The aim of this study was to assess the potential of a novel homeopathic complex medicine in managing bovine mastitis. METHODS: Twenty-four lactating Holstein cows with mastitis were divided into two groups: the homeopathic complex group received a homeopathic complex daily for 60 days at a dose of 20 g/d; the placebo group received the calcium carbonate vehicle without homeopathic medicines at the same dose and repetition. The main outcome measure was somatic cell count (SCC; cells/mL), with additional outcome measures including milk production (kg/d), milk constituents (percentage of protein, fat, lactose and total milk solids), and serum levels of cortisol, glucose, ammonia and lactic acid. All outcomes were measured at the beginning of the study and after 30 and 60 days. Milk samples were also collected from all animals at the beginning of the study, confirming a high (>0.2) MAR index for isolated bacterial cultures. RESULTS: Assessment of SCC showed a statistically significant difference favoring the homeopathic complex versus placebo group at day 60. A reduction in serum cortisol levels and an increase in fat, lactose and total milk solids in animals treated with the homeopathic complex at day 60 were also seen. Other outcome measures did not show statistically significant inter-group differences. CONCLUSION: The results of this non-randomized, open-label, placebo-controlled trial suggest the potential for a novel homeopathic complex medicine in management of multiple antibiotic-resistant bovine mastitis, thus offering dairy farmers an additional option to antibiotics and making dairy products safer for consumer health and milk production more sustainable.

Kangfuxin liquid reduces the ultraviolet B-induced photodamage of HaCaT cells by regulating autophagy.

Kangfuxin liquid (KFX), an extract of the American cockroach, has been clinically proven to be effective in various skin damage disorders, but there are no reports on its use in photodamage. We explored the effect of KFX on ultraviolet B (UVB)-induced photodamage and whether its mechanism was related to autophagy. We found that KFX treatment reduced UVB-induced reactive oxygen species production and improved the vitality of cells inhibited by UVB irradiation. The expression of LC3 (A/B), which was inhibited after UVB irradiation, could be rescued by KFX treatment. Furthermore, KFX may upregulate the level of cellular autophagy by regulating the AMPK-mTOR signaling pathway. When the autophagy inhibitor wortmannin was used to inhibit autophagy, the protective effect of KFX on cells was diminished or even disappeared. Our study suggests that KFX may resist UVB-mediated oxidative stress damage of HaCaT through the induction of autophagy.

Review on Processing Methods of Toxic Chinese Materia Medica and the Related Mechanisms of Action.

Toxic Chinese materia medica (CMM) has both pharmacological activities and toxic effects. Based on thousands of years of experience in the application of CMMs, people have explored many practical processing methods of CMMs, also known as "Pao Zhi", to reduce/control toxicity and preserve/enhance efficacy. Toxic CMMs have been used throughout China's hospitals. Yet, the production and use of toxic CMM should be carried out in accordance with the Chinese pharmacopoeia (ChP) and the processing regulations formulated by the health administrative departments of provinces, autonomous regions, and municipalities directly under the Central Government. This paper summarizes the current understanding and awareness of toxicity and 45 toxic CMMs, the commonly used processing methods of toxic CMMs recorded in the 2020 edition of ChP, and the changes in the chemical component, toxicity, or efficacy profiles after processing. This review may provide useful information for the processing methods of toxic CMMs worldwide. We believe that with an in-depth study and understanding of toxic CMMs combined with a standardized application, the toxicity of CMMs will be predictable and controllable in the future.

Efficacy of Individualized Homeopathic Medicines in the Treatment of Menopausal Syndrome: Double-Blind, Randomized, Placebo-Controlled Trial.

Objectives: Menopausal symptoms are systemic symptoms that are associated with estrogen deficiency after menopause. Although widely practiced, homeopathy remains under-researched in menopausal syndrome in terms of quality evidence, especially in randomized trials. The efficacy of individualized homeopathic medicines (IHMs) was evaluated in this trial against placebos in the treatment of the menopausal syndrome. Design: Double-blind, randomized (1:1), two parallel arms, placebo-controlled trial. Setting: Mahesh Bhattacharyya Homoeopathic Medical College and Hospital, Howrah, West Bengal, India. Subjects: Sixty women with menopausal syndrome. Interventions: Group 1 (n = 30; IHMs plus concomitant care; verum) versus group 2 (n = 30; placebos plus concomitant care; control). Outcome measures: Primary-the Greene climacteric scale (GCS) total score and menopause rating scale (MRS) total score, and secondary-the Utian quality of life (UQOL) total score; all of them were measured at baseline and every month up to 3 months. Results: Intention-to-treat sample (n = 60) was analyzed. Group differences were examined by two-way (split-half) repeated-measure analysis of variance, primarily taking into account all the estimates measured at monthly intervals, and secondarily, by unpaired t tests comparing the estimates obtained individually every month. The level of significance was set at p < 0.025 two-tailed. Between-group differences were nonsignificant statistically-GCS total score (F1, 58 = 1.372, p = 0.246), MRS total score (F1, 58 = 0.720, p = 0.4), and UQOL total scores (F1, 58 = 2.903, p = 0.094). Some of the subscales preferred IHMs significantly against placebos-for example, MRS somatic subscale (F1, 56 = 0.466, p < 0.001), UQOL occupational subscale (F1, 58 = 4.865, p = 0.031), and UQOL health subscale (F1, 58 = 4.971, p = 0.030). Sulfur and Sepia succus were the most frequently prescribed medicines. No harm or serious adverse events were reported from either group. Conclusions: Although the primary analysis failed to demonstrate clearly that the treatment was effective beyond placebo, some significant benefits of IHMs over placebo could still be detected in some of the subscales in the secondary analysis. Clinical trial registration number: CTRI/2019/10/021634.

Nanomaterial Characterisation of Diluted Platina and Alcohol Control Samples.

BACKGROUND: The healing effects of homeopathic ultra-high potencies (UHPs) have always been a puzzle for material science, though recent research papers have now characterised the nanomaterial nature of several such UHPs. This study aimed to analyse the material content of clinically used potencies of the homeopathic medicine Platina (platinum) compared with alcohol control samples. METHODS: Potencies of Platina were analysed under dynamic light scattering (DLS), high resolution transmission electron microscopy (HRTEM) with energy dispersive spectroscopy (EDS) and selected area electron diffraction (SAED) to identify the nanomaterial content. As control samples, both unsuccussed and potencies of alcohol were analysed by using DLS and HRTEM. RESULTS: Platina 30c to CM: Nanoparticles were identified under DLS (mean particle size varying from 1.3 nm in 30c to 6.5 nm in CM) and HRTEM (particle size varying from 3.31 to 12.7 nm in 30c to 1.94 to 8.54 nm in CM). EDS confirmed the presence of platinum in all the samples of Platina. SAED analysis of Platina 30c, 200c, 1M and 10M confirmed also the presence of platinum dioxide (PtO2). For control samples, DLS and the HRTEM analyses of pharmaceutical grade unsuccussed alcohol and potentized Alcohol (6c, 12c and 30c) did not show any particles. CONCLUSION: Homeopathic potentization generated NPs of platinum in ultra-dilutions. NPs in potencies of Platina showed platinum in EDS and PtO2 in SAED. Importantly, control samples of alcohol did not show the presence of particles under DLS or HRTEM.

Effect of Ointments of Sulphur or Pyrogenium on Larvae of Cochliomyia hominivorax (Diptera: Calliphoridae).

BACKGROUND: Myiasis by Cochliomyia hominivorax (Diptera: Calliphoridae) is a serious problem in animal health in tropical and sub-tropical regions. Ointment-type preparations are a good option of formulation in cases of myiasis in farm and pet animals. Sulphur and Pyrogenium have already shown in-vitro efficacy on C. hominivorax. This article describes an in-vitro experiment to test the inhibition of development from exposing larvae of C. hominivorax to two homeopathic ointments (prepared individually with Sulphur or Pyrogenium). METHODS: The homeopathic ointments were produced by mixing sterile lanolin, tocopherol and homeopathic medicine on a hydroalcoholic basis according to the Brazilian Homeopathic Pharmacopoeia. Larvae were obtained from naturally occurring myiases in sheep (wild larvae) or from a laboratory colony. The test consisted of exposing a group of 10 third-stage C. hominivorax wild larvae in contact with Sulphur or Pyrogenium ointment, or a group of 15 laboratory-propagated larvae in contact with the alcoholic vehicle of the ointment or homeopathic medicines prepared in sterile water (Sulphur or Pyrogenium), and observing the effect on the development, longevity and fertility of the blow-fly specimens. RESULTS: The C. hominivorax larval inhibition rate was 90.0% for the Sulphur ointment group and was 86.0% for the Pyrogenium ointment group. The non-alcoholic vehicle and the alcoholic vehicle inhibited the development of 24.0% and 22.08% of the larvae respectively. Sulphur prepared in sterile water inhibited the development of 74.67% and Pyrogenium in sterile water inhibited 73.33% of larvae. Specimens that survived contact with homeopathic ointments had their longevity decreased and did not reproduce. CONCLUSION: Ointments of Sulphur or Pyrogenium were able to inhibit the development of C. hominivorax larvae. The ointment vehicle was harmless.

The liquid Kangfuxin (KFX) has efficient antifungal activity and can be used in the treatment of vulvovaginal candidiasis in mice.

Vulvovaginal candidiasis (VVC) is an infectious disease caused mainly by Candida albicans. Kangfuxin (KFX) is a traditional Chinese medicine preparation made from Periplaneta americana extracts, which promotes wound healing and enhances body immunity and also acts as an antifungal agent. Here, we evaluated the effect of KFX in the treatment of VVC in vitro and in vivo. The minimum inhibitory concentration (MIC50 ) of KFX against C. albicans ranged from 7·65 to 20·57%. In addition, KFX was more efficient than fluconazole (FLC) in inhibiting the drug-resistant C. albicans, and the effect was more intense after 8 h. The KFX treatment also exhibited good activity in vivo. It restored the body weight and reduced the vulvovaginal symptoms in mice induced with VVC. It downregulated the expression of the hyphae-related gene, HWP1, thus inhibiting the growth and development of C. albicans hyphae. It also increased the number of neutrophils and promoted the secretion of interleukin-17A (IL-17A); however, the levels of interleukin-8 (IL-8) and interleukin-1ß (IL-1ß) decreased in mice with VVC. We deduce that KFX effectively treats vaginal candidiasis in two ways: by inhibiting the growth and development of mycelia to reduce colonization of C. albicans and by promoting the secretion and release of IL-17A and neutrophils in high numbers to fight C. albicans infection. This study provides a theoretical basis for the use of KFX for the clinical treatment of VVC.

Efficacy of Chininum Sulphuricum 30C against Malaria: An in vitro and in vivo Study.

BACKGROUND: New effective, economical and safe antimalarial drugs are urgently needed due to the development of multi-drug-resistant strains of the parasite. Homeopathy uses ultra-diluted doses of various substances to stimulate autoregulatory and self-healing processes to cure various ailments. The aim of the study was to evaluate the in vitro and in vivo antimalarial efficacy of a homeopathic drug, Chininum sulphuricum 30C. METHODS: In vitro antiplasmodial activity was screened against the P. falciparum chloroquine-sensitive (3D7) strain, and cell viability was assessed against normal human dermal fibroblasts and HepG2 cells. Suppressive, preventive and curative studies were carried out against P. berghei-infected mice in vivo. RESULTS: Chininum sulphuricum (30C) revealed good antiplasmodial activity in vitro, with 92.79 ± 6.93% inhibition against the 3D7 strain. The cell viability was 83.6 ± 0.6% against normal human dermal fibroblasts and 95.22 ± 5.1% against HepG2 cells. It also exhibited suppressive efficacy with 95.56% chemosuppression on day 7 with no mortality throughout the follow-up period of 28 days. It also showed preventive activity against the disease. Drug treatment was also safe to the liver and kidney function of the host as evidenced by biochemical studies. CONCLUSION: Chininum sulphuricum 30C exhibited considerable antimalarial activity along with safety to the liver and kidney function of the host.

In-Vitro Evaluation of Antimicrobial Activities of Escherichia coli, Klebsiella pneumoniae, Salmonella typhi, Neisseria gonorrhoeae, and Candida albicans Nosodes.

BACKGROUND: This study presents the results of the minimum inhibitory concentration (MIC) assay of a series of nosodes: namely Escherichia coli, Klebsiella pneumoniae, Salmonella typhi, Neisseria gonorrhoeae, and Candida albicans. Each was tested against its corresponding infection as well as cross infections. METHODS: In-vitro efficacy of polyvalent nosodes was tested using the MIC assay technique. The nosodes, namely C. albicans polyvalent nosode (35c, 100c), N. gonorrhoeae (35c), K. pneumoniae (35c, 100c), E. coli polyvalent nosode (35c, 100c) and Salmonella typhi polyvalent nosode (30c, 100c), were tested along with positive and negative controls. Nosodes were studied in different potencies and at 1:1 dilution. RESULTS: C. albicans polyvalent nosode 35c, 100c, N. gonorrhoeae 35c, and positive control amphotericin B showed inhibition of the growth of C. albicans species. K. pneumoniae 35c, E. coli polyvalent nosode 100c, and meropenem (positive control) showed inhibition of the growth of K. pneumoniae; this effect was not seen with ceftriaxone, ofloxacin and amoxicillin antibiotics. E. coli polyvalent nosode 30c in 10% alcohol (direct and dilution 1:1) and the positive controls ciprofloxacin, ofloxacin, and amoxicillin showed inhibition of the growth of E. coli. The S. typhi polyvalent nosode 30c in 10% alcohol showed inhibition of growth of S. typhi. CONCLUSION: This study reveals that the tested nosodes exhibited antibacterial potential against the corresponding micro-organisms and against other selected organisms studied using this assay.

Evidence for Reversal of Immunosuppression by Homeopathic Medicine to a Predominant Th1-type Immune Response in BALB/c Mice Infected with Leishmania donovani.

BACKGROUND: Visceral leishmaniasis (VL) is a neglected tropical disease that is fatal if treatment is not given. The available chemotherapeutic options are unsatisfactory, and so complementary therapies like homeopathy might be a promising approach. METHODS: A nosode from a pure axenic culture of Leishmania donovani was prepared and screened for its anti-leishmanial potential both in an in-vitro and an in-vivo experimental approach. RESULTS: Leishmania donovani amastigote promastigote nosode (LdAPN 30C) exhibited significant anti-leishmanial activity against the promastigote forms of Leishmania donovani and was found to be safe. A study conducted on VL-infected mice revealed that LdAPN 30C resolved the disease by modulating the host immune response toward the Th1 type through upregulating the pro-inflammatory cytokines (IFN-γ and IL-17) and inducing nitric oxide (NO) levels in the infected macrophages. The hepatic parasite load was also found to be significantly decreased. The nosode was found to be safe, as no histological alterations in the liver or kidney were observed in the animals treated with the LdAPN 30C. CONCLUSION: This is the first study in which an axenic culture of Leishmania donovani has been used for the preparation of a homeopathic medication. The study highlights the anti-leishmanial and immunomodulatory potential of a homeopathic nosode in experimental VL.

Assessment of the cytoprotective effect of the homeopathic compound Canova® on African green monkey kidney (VERO) cell line exposed to the drug dipyrone sodium.

Dipyrone or metamizole is one of the most frequently used analgesic worldwide. Despite its widespread use, this drug may exert genotoxic and cytotoxic effects on lymphocytes. Therefore, studies with therapeutic agents that may provide protection against these effects are important. The homeopathic compound Canova® (CA) appears to be a beneficial candidate for preventing DNA damage and cellular lethality, since this compound acts as an immunomodulator associated with cytoprotective actions. Hence, the aim of the present investigation was to determine the potential cytoprotective effects of CA using cell line VERO as a model. VERO cells were incubated with sodium dipyrone and subsequently subject to the comet, apoptosis and immunocytochemistry assays. Data demonstrated that sodium dipyrone induced an increase in DNA damage index (DI) employing the comet assay. However, when VERO cells were co-treated with CA at the three concentrations studied, a significant reduction in DI was observed, indicating an antigenotoxic effect attributed to CA. Further dipyrone induced an elevation in %apoptosis at 24 and 48 hr. However, when dipyrone was co-incubated with CA, a significant reduction in %apoptosis was noted at the three concentrations of CA employed. Results from immunocytochemical analysis showed a rise in the expression of caspase 8 and cytochrome C when cells were exposed to dipyrone. In contrast, co-treatment of dipyrone and CA significantly reduced the effect of dipyrone. Therefore, evidence indicated that CA acted as an anticytotoxic and antigenotoxic agent counteracting damage induced by dipyrone.

Kangfuxin Liquid Ameliorates Dextran Sulfate Sodium (DSS)-Induced Acute Ulcerative Colitis in Mice by Modulating Immune Response and Suppressing Inflammation.

BACKGROUND The aim of this study was to determine the effect of kangfuxin liquid (KFXL) on inflammatory response, and its underlying mechanism in treating acute ulcerative colitis (UC) in mice induced by dextran sulfate sodium (DSS). MATERIAL AND METHODS Mice were provided drinking water containing DSS (3%) for 7 days to induce acute enteritis. The mice were divided into 6 groups: a control group, a DSS-induced (vehicle) group, a sulfasalazine (SASP) group, and low-, medium-, and high-dose kangfuxin liquid groups. Disease activity index (DAI), colon mucosa damage index (CMDI), histopathological score (HS), and organ index were monitored daily. The levels of interleukin-1ß (IL-1ß), interleukin-10 (IL-10) in serum and interleukin-17 (IL-17) and epidermal growth factor (EGF) in colon tissue were assessed by enzyme-linked immunosorbent assay (ELISA). Flow cytometry was used to assess the changes of T lymphocyte subsets in spleens of mice to evaluate the therapeutic effect of drugs on acute UC in mice. RESULTS Different doses of kangfuxin liquid reduced the DAI, CMDI, and HS scores (P<0.01 or P<0.05) of acute UC mice, reduced the level of IL-1ß and IL-17 in serum, increased the expression of IL-10 in serum and EGF in colon tissue, increased the number of CD3⁺ T cells, and decreased the level of CD4⁺ T cells and the ratio of CD4⁺/CD8⁺. CONCLUSIONS Kangfuxin liquid has a therapeutic effect on DSS-induced acute UC in mice, and its mechanism of action may be associated with regulating immune function and reducing intestinal inflammatory response.

The effects and mechanism of Kangfuxin on improving healing quality and preventing recurrence of gastric ulcer.

This study investigated the gastroprotective effects and possible mechanism of Kangfuxin (KFX), an ethanol extract of Periplaneta americana L. (Dictyoptera; Blattidae), on improving healing quality and preventing recurrence of gastric ulcer. The effects of KFX were investigated in patients treated with endoscopic submucosal dissection (ESD), gastric ulcer animal model, and rat gastric mucosal cells and fibroblasts. Moreover, the relationship between KFX and p38/NF-κB pathway were explored both in vivo and in vitro. In patients, KFX exhibited protective effects against gastric ulcers and resulted in a decrease in the CD3 expression. In vivo animal experiments confirmed that KFX accelerated ulcer healing by promoting neovascularization (increased CD34 expression), suppressing inflammation (decreased interleukin-1ß (IL-1ß), myeloperoxidase (MPO), tumor necrosis factor α (TNF-α), intercellular adhesion molecule-1 (ICAM-1), and IL-8 expression), and enhancing growth factor expression, including the epidermal growth factor receptor (EGFR) and hepatocyte growth factor (HGF). In vitro experiments demonstrated that treatment with 10% KFX rat serum decreased IL-1ß, IL-1Ra, SIL-1RAP, TNF-α, and ICAM-1 expression in rat gastric mucosal cells or fibroblasts and increased IL-1R expression compared to that in the group treatment with 10% normal rat serum. Furthermore, KFX inhibited the activation of p38/NF-κB pathway both in vivo and in vitro. In conclusion, KFX treatment could effectively improve healing quality and prevent gastric ulcer recurrence, which might be attributed to neovascularization, suppressed inflammation, and enhanced growth factor expression. The p38/NF-κB pathway may be one of important mechanism to mediate the effects of KFX.

The Toxicity and Attenuation Methods of Toxic Chinese Materia Medica for its Reasonable Application: A Review.

Over a millennia, traditional Chinese medicine (TCM) has been used to treat various diseases in China. In recent years, more and more Chinese materia medica (CMM) have been studied in scientific research projects, applied in clinical practice, and their extracts have even appeared in some health products. However, the toxicity of some CMM is often overlooked, including hepatotoxicity, nephrotoxicity, neurotoxicity, cardiotoxicity, etc. In this review, the toxic components and their toxicological mechanisms of some toxic CMM were listed according to the chemical structure classification of toxic components. Afterwards, the traditional methods (processing and compatibility) and modern methods (structural modification, biotransformation, etc.) of attenuation of CMM were discussed. Since ancient times, it has been said that "fight fire with fire, fight poison with poison," and toxic CMM are of great significance in the treatment of difficult and severe diseases. The rational application of toxic CMM and their components in clinical practice was also exemplified in this review. While the pharmacological effects of TCMs have been emphasized, the scientific attenuation and rational application of toxic components should be concerned. We hope this review can provide a reference for future related research.

An investigation of the pharmacological applications used for the Ancient Egyptian systemic model 'ra-ib' compared with modern Traditional Chinese Medicine.

ETHNOPHARMACOLOGICAL RELEVANCE: Ancient Egyptian texts only offer glimpses into their conceptual understandings of the inner-body and illness manifestation. Explanations of how prescribed materia medica were believed to work are rare and obscure, often resulting in modern approximations for ancient terminology such as 'ra-ib'-an ancient Egyptian classification predominantly translated as 'stomach'-leading to misunderstandings of historical texts, and therefore their use of pharmacology. AIM OF THE STUDY: To investigate the ra-ib and the explanatory models of illness from the Egyptian perspective, and to explore the link between these and the prescribed selection of materia medica. To then compare the conceptual mechanics of these treatment strategies with those of another non-Western tradition-namely Traditional Chinese Medicine (TCM)-to provide further insight into potential conceptual frameworks. MATERIALS AND METHODS: We conducted a case study of a unit of Ancient Egyptian texts focusing on the ra-ib. Totalling 34 prescriptions, the first stage lexicographically analysed the texts using cognitive linguistic and translation theories to produce our new understanding. This enabled our comparison of the mechanics of materia medica usage within these texts with those found in TCM outlined by the Pharmacopoeia of the Peoples Republic of Pharmacopeia of the People's Republic of China 2015 for the relevant ingredients. RESULTS: the study demonstrated that-rather than denoting the organ 'stomach'-ra-ib instead constitutes a system running from the mouth, downward to the anus. This is best translated as 'inner thoroughfare', and changes the way in which we attempt to understand potential motivations in the selection of ingredients. By exploring common themes in the use of eleven securely translated ingredients from the Egyptian corpus and the Pharmacopoeia of the People's Republic of China-representing a modern traditional system which understands the body via a series of interconnected systems-we were able to highlight certain themes which might be 'universal' to system-based traditions; this provided new insights into the Egyptian motivations for treatment selection. CONCLUSIONS: Having gained the ancient view of the body and illness, cultural comparisons are important for providing further potential insights and clarifications of a discontinued historical healing tradition. The new understanding of the ra-ib from our study greatly changes the way in which we understand the dynamics of Egyptian ethnopharmacological source material from this period.

Effects of Hangeshashinto on the nasal physiological function: An in vitro study.

OBJECTIVE: Hangeshashinto is a Japanese Kampo medicine applied for the treatment of oral mucositis and gastroenteritis. Hangeshashinto exhibits broad-spectrum antibacterial activity and suppresses prostaglandin (PG)E2 production in the mucosa and has the ability to improve the inflammatory condition. In addition to these effects, because cAMP, a composition of Hangeshashinto, facilitates ciliary beat, Hangeshashinto could also improve the physiological function of the nasal mucosa, consist of ciliated epithelium, but details were unknown. METHODS: This study was aimed to investigate the effects of Hangeshashinto on the nasal mucosa. Healthy nasal mucosal sections were collected from the nasal septum of ten Japanese white rabbits, placed in a collagen dish for tissue culture, and rinsed with two different concentrations of Hangeshashinto solution (1.0%, n = 10 and 2.5%, n = 10) and cAMP solution (50µM, n=10 and 100 µM, n=10) or saline (control, n = 10). Ciliary beat frequency (CBF) as a physiological function of the nasal mucosa was recorded at 1, 3 and 7 days after rinsing, and histological evaluation of epithelial damage was performed at 7 days after rinsing. RESULTS: CBF in the 1.0% but not in the 2.5% Hangeshashinto group, increased at 3 and 7 days compared with that in the control group (p < 0.05). This trend was also observed in the CBF in the 100 µM cAMP group, significant difference was not observed between the CBF of the 1.0% Hangeshashinto group and the 100 µM cAMP group at 1, 3 and 7 days after rinsing (p > 0.05). Histological score only in the 2.5% Hangeshashinto group was lower than that in the control group (p < 0.05), while a significant decline was not observed in the other groups compared to that in the control group (p > 0.05). CONCLUSION: Our results suggest that 1.0% Hangeshashinto solution facilitates the physiological function of the nasal mucosa by promoting ciliary functions without histological damage of cilia epithelium. When applied with the appropriate concentration, Hangeshashinto could have ability to improve the physiological functions of the nasal mucosal epithelium.

Silicea terra and Zincum metallicum Modulate the Activity of Macrophages Challenged with BCG In Vitro.

BACKGROUND: The homeopathic medicines Silicea terra (Sil) and Zincum metallicum (Zinc) modulate macrophage activity and were assessed in an experimental study in-vitro for their effects on macrophage-BCG (Bacillus Calmette-Guérin) interaction. METHODS: RAW 264.7 macrophages were infected with BCG, treated with different potencies of Sil and Zinc (6cH, 30cH and 200cH) or vehicle, and assessed 24 and 48 h later for bacilli internalization, hydrogen peroxide (H2O2) and cytokine production, and lysosomal activity. RESULTS: Treatment with vehicle was associated with non-specific inhibition of H2O2 production to the levels exhibited by uninfected macrophages. Sil 200cH induced significant reduction of H2O2 production (p < 0.001) compared with the vehicle and all other treatments, as well as higher lysosomal activity (p ≤ 0.001) and increased IL-10 production (p ≤ 0.05). Such effects were considered specific for this remedy and potency. The number of internalized bacilli was inversely proportional to Zinc potencies, with statistically significant interaction between dilution and treatment (p = 0.003). Such linear-like behavior was not observed for Sil dilutions: peak internalization occurred with the 30cH dilution, accompanied by cellular degeneration, and IL-6 and IL-10 increased (p ≤ 0.05) only in the cells treated with Sil 6cH. CONCLUSION: Sil and Zinc presented different patterns of potency-dependent effect on macrophage activity. Bacterial digestion and a balanced IL-6/IL-10 production were related to Sil 6cH, though reduced oxidative stress with increased lysosomal activity was related to Sil 200cH. Degenerative effects were exclusively related to Sil 30cH, and potency-dependent phagocytosis was related only to Zinc.

[Effects of a homeopathic medication on clinical signs of canine atopic dermatitis]. / Wirkung eines homöopathischen Arzneimittels auf die klinische Symptomatik von Hunden mit atopischer Dermatitis.

OBJECTIVE: A commercially available medication containing homeopathic ingredients showed first signs of success in atopic dermatitis in dogs. The aim of this case series was to evaluate the effect of the preparation in a larger number of dogs with atopic dermatitis. MATERIAL AND METHODS: Ten atopic dogs received the oral homoeopathic combination preparation daily for 3 weeks according to the manufacturer's specifications. The diagnosis of atopic dermatitis was made previously by medical history, clinical examination and exclusion of differential diagnoses. Skin infections with bacteria and yeasts were excluded by clinical examination and cytological evaluation of impression smears. In food-allergic dogs, an elimination diet was fed at least 2 months prior and during the entire study period. Patients with suspected or confirmed flea allergy received flea control for at least 1 month prior to and during the study. The clinical signs were evaluated before and after therapy using a validated Pruritus Visual Analogue Acale (PVAS) and the Canine Atopic Dermatitis Lesion Index (CADLI). The coat quality was assessed by the owners. Possible adverse effects were recorded at the recheck. RESULTS: There were no significant changes in the lesion score (Wilcoxon test, p = 1.0), pruritus score (paired t test, p = 0.34) and coat quality (paired t test, p = 0.34) over the duration of treatment. Only one patient showed a slight improvement in itching and coat quality. No side effects were observed. CONCLUSION AND CLINICAL RELEVANCE: In this case series, the tested homoeopathic preparation did not show a positive effect on the clinical signs of canine atopic dermatitis.

Application of "spider-web" mode in discovery and identification of Q-markers from Xuefu Zhuyu capsule.

BACKGROUND: The selection of quality control indicators in a complex system is a key scientific issue for the study of Chinese materia medica (CMM), which is directly related to its safety and efficacy. In order to scientifically understand and control the quality of CMM, quality marker (Q-marker) has been recently raised as a new concept, which provided a novel research idea for the quality control and evaluation of CMM. PURPOSE: By a new and integrated "spider-web" mode, Q-markers of Xuefu Zhuyu capsule (XZC) were comprehensively uncovered, conducing to great improvement of quality control of XZC. METHODS: Mainly established by three dimensions derived from six variables including content, stability and activity, "spider-web" mode was constructed to evaluate Q-marker property of candidate compounds by taking regression area of the tested compounds into account. RESULTS: The candidate compounds with larger regression area were preferentially adopted as Q-markers, which should possess the satisfactorily integrated properties of content, stability and activity. Six compounds, naringin, isoliquiritin, paeoniflorin, protocatechuic acid, neohesperidin and ferulic acid, were identified and preferred as Q-markers of XZC. CONCLUSION: Based on "spider-web" mode, Q-markers from Xuefu Zhuyu capsule were successfully screened, which would substantially perform quality control of XZC and prove the feasibility of "spider-web" mode in solving the selection of quality control indicators from compound formulae.
