Understanding Why Homeopathic Medicines are Used for Menopause: Searching for Insights into Neuroendocrine Features.

BACKGROUND: Menopause is a physiological event that marks the end of a woman's reproductive stage in life. Vasomotor symptoms and changes in mood are among its most important effects. Homeopathy has been used for many years in treating menopausal complaints, though clinical and pre-clinical research in this field is limited. Homeopathy often bases its prescription on neuropsychiatric symptoms, but it is unknown if homeopathic medicines (HMs) exert a neuroendocrine effect that causes an improvement in vasomotor symptoms and mood during menopause. OBJECTIVES: The study's objectives were to address the pathophysiological changes of menopause that could help in the understanding of the possible effect of HMs at a neuroendocrine level, to review the current evidence for two of the most frequently prescribed HMs for menopause (Lachesis mutus and Sepia officinalis), and to discuss the future directions of research in this field. METHODS: An extensive literature search for the pathophysiologic events of menopause and depression, as well as for the current evidence for HMs in menopause and depression, was performed. RESULTS: Neuroendocrine changes are involved in the pathophysiology of vasomotor symptoms and changes in mood during menopause. Gonadal hormones modulate neurotransmitter systems. Both play a role in mood disorders and temperature regulation. It has been demonstrated that Gelsemium sempervirens, Ignatia amara and Chamomilla matricaria exert anxiolytic effects in rodent models. Lachesis mutus and Sepia officinalis are frequently prescribed for important neuropsychiatric and vasomotor symptoms. Dopamine, a neurotransmitter involved in mood, is among the constituents of the ink of the common cuttlefish, Sepia officinalis. CONCLUSION: Based on all the pathophysiologic events of menopause and the improvement in menopausal complaints that certain HMs show in daily practice, these medicines might have a direct or indirect neuroendocrine effect in the body, possibly triggered via an as-yet unidentified biological mechanism. Many unanswered questions in this field require further pre-clinical and clinical research.

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.

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.

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.

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.

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.

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.

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.

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.

The Complexity of the Homeopathic Healing Response Part 1: The Role of the Body as a Complex Adaptive System in Simillimum-Initiated Recovery from Disease.

BACKGROUND: The concepts of complex systems science enhance the understanding of how people develop and recover from disease. Living systems (human beings, animals, and plants) are self-organizing complex adaptive systems (CAS): that is, interconnected networks. CAS maintain life by initiating and carrying out non-linear dynamical changes to optimize survival fitness and function in the context of an ever-changing environment. AIMS: In Part 1 of this two-part paper, we relate concepts from complex systems science to homeopathic healing. The systemic changes of homeopathic healing involve adaptive patterns of responses to salient signals (similia) for reversing disease patterns and generating emergent multi-symptom healing over time. METHODS AND RESULTS: This narrative review relates homeopathic clinical practice theory to complex systems and network research. Homeopathic medicines communicate individually salient environmental information to the organism, with effects that are multi-system and indirect. The body's defense mechanisms recognize the self-similar information that the correctly chosen simillimum medicine at low dose conveys as a weak external/internal environmental stressor or danger signal (hormetin) to mobilize neural and cellular defenses. The body networks then use endogenous cell to cell signaling and amplify the small magnitude signal information. The results are disproportionately large: that is, non-linear, adaptive, modifications across the inter-connected self-organized biological networks/sub-systems of the body. CAS amplification mechanisms for small or weak signals include stochastic resonance, time-dependent sensitization, and hormesis. CONCLUSIONS: The body as a complex system has the capacity for self-organization, emergence and self-similarity over global (overall health and wellbeing) and local (organ) levels of organization. These features are key for future research on the systemic healing that evolves over time during individualized homeopathic treatment.

The Complexity of the Homeopathic Healing Response Part 2: The Role of the Homeopathic Simillimum as a Complex System in Initiating Recovery from Disease.

BACKGROUND: Evidence indicates that homeopathic medicines are complex self-organizing nano-scale systems that generate unique low-intensity electromagnetic signals and/or quantum coherence domains. In Part 1, we reviewed relevant concepts from complex adaptive systems science on living systems for the nature of homeopathic healing. AIM: In Part 2, we discuss the complex-system nature of homeopathic medicines. The aim is to relate the evidence on the nature and properties of homeopathic medicines to the complex systems model for homeopathic healing. METHODS AND RESULTS: The work is a narrative review, with complexity model development for the nature of homeopathic medicines. Studies suggest that homeopathic manufacturing generates nano-structures of source material, silica and silicon quantum dots if succussed in glassware or including botanical source materials; or carbon quantum dots if succussed in plastic or including any organic source materials, as well as solute-induced water nano-structures carrying medicine-specific information. On contact with physiological fluids (e.g., blood plasma), there is evidence that nano-structures additionally adsorb individualized patterns of the recipient's own proteins on to their surfaces to create a unique protein corona coat (shell). Thus, the simillimum may generate a personalized biological identity upon administration. Consequently, a medicine can serve as an individually salient, self-similar information carrier, whose protein corona constituent pattern reflects the individual's current internal state of health/disease. Homeopathic medicine complexity emerges from interactions of the component parts from source, silica from glassware or carbon from plastic containers, solvents (lactose, water, ethanol), adsorbed biomolecule layers from plant or animal sources, and adsorbed biomolecules of the recipient. Low doses of these complex medicines can act as biological signaling agents to initiate hormesis via a network-wide pattern of adaptive responses by the recipient complex adaptive system, rather than as conventional pharmaceutical drugs. Biological mediators of adaptive responses include inter-connected network elements of the cell danger/damage defense system: for example, gene expression, reactive oxygen species, heat shock proteins, cytokines, macrophages, T-cells, and associated brain-immune system mediator pathways. CONCLUSIONS: Every homeopathic medicine is a complex nano-scale system involving multiple inter-connected, interacting components, and emergent properties. Simillimum individualization derives from formation of a unique personalized protein corona shell adsorbed to the reactive surface of the homeopathic nano-structures on contact with the recipient's body fluids. Low doses of such complex nano-structures initiate the adaptive processes of hormesis to mobilize endogenous healing of a disease state. The capacity for self-organization and self-similarity in complex systems is the key to future research on the nature of homeopathic medicines and systemic healing during individualized homeopathic treatment.

Oviductus Ranae protein hydrolyzate prevents menopausal osteoporosis by regulating TGFß/BMP2 signaling.

PURPOSE: It is known that menopausal osteoporosis (MOP) is the most typical form of osteoporosis, which is characterized by low bone mass and microstructure damage of the bone tissue, leading to increased bone fragility and risk of fracture. This study aimed to evaluate the protective effects of Oviductus Ranae protein hydrolyzate (ORPH) on the MOP in vivo. METHODS: Osteoporosis model was induced by ovariectomy, treated with ORPH 150 or 75 mg kg-1. Body weight and bone mineral density (BMD) of rats were measured at the beginning and the end of the experiment, and femoral maximum load was determined immediately after killing. The expression levels of alkaline phosphatase (ALP), Smad4, tartrate acid phosphatase (TRAP), BMP2, Runx2, CPB, ColI and osteocalcin were examined by RT-PCR or western-blotting. HE staining was used to observe the pathological changes in the femurs. Immunohistochemistry was used to detect the expression of ALP and BMP2. All data were analyzed by SPSS 13.0. RESULTS: The results revealed that ORPH had no effect on the weight of normal and osteoporotic rats. ORPH could significantly improve the femur BMD and increase the maximum load of the osteoporotic rats. ORPH could significantly upregulate the expression level of bone formation makers, ALP, osteocalcin, ColI, and Runx2, and downregulate the expression level of bone resorption marker, TRAP. In the ORPH group, the expression levels of BMP2, Smad4, and CPB of key proteins in the TGFß/BMP2 signaling pathway were significantly upregulated. In addition, immunohistochemistry showed that ALP and BMP2 expression in femurs of the ORPH group was stranger. H&E staining showed that ORPH (150 mg kg-1) significantly increased the thickness of trabeculae and decreased fracture risk. CONCLUSION: Collectively, ORPH plays a role in the prevention and treatment of osteoporosis, which may be a potential anti-osteoporosis drug.

Nineteenth-Century Homeopathic Materia Medica Texts Predict Source Materials Whose Physiological Actions Influence Thyroid Activity.

INTRODUCTION: The homeopathic materia medica contains hundreds of thousands of observations collected over the course of two centuries. It includes both clinical observations of potentized medicines and observations of the actions of potentized medicines on healthy subjects (provings). This current study was undertaken to determine the degree to which observations within the materia medica were associated with the physiological mechanisms for thyroid activity-inhibiting substances in their undiluted state. MATERIALS AND METHODS: Four specific symptoms for iodine deficiency were selected to describe the hypothyroid state: (1) generalized aggravation by or sensitivity to cold; (2) chronic painless hoarseness; (3) goiter; (4) painless diffuse non-scarring alopecia. Symptom representation for the four selected symptoms within the homeopathic materia medica was compared for 2 halogen inhibitors, for 3 substances that influence thyroid hormone target tissues, for 6 substances known or suspected to increase thyroid-stimulating hormone or decrease thyroid hormone levels, and for 11 substances not known to inhibit thyroid activity. To avoid knowledge bias, only those compilations of materia medica whose publication dates preceded the discoveries of crucial aspects of thyroid physiology were used as source materials for investigation. RESULTS: Homeopathic medicines derived from 11 substances with mechanisms for inhibition of thyroid activity were more likely to exhibit selected symptoms than the medicines derived from the 11 substances without known physiological mechanisms for thyroid activity inhibition. The difference between groups was analyzed via the Mann-Whitney non-parametric U test and was statistically significant to p < 0.01. After observations obtained from provings alone were removed from analysis, the difference remained significant to p < 0.01. Only the two halogen inhibitors of iodine (bromine and fluoric acid) and one of the influencers of thyroid hormone target tissue (calcium carbonate) were significantly goitrogenic. CONCLUSIONS: With respect to thyroid activity inhibition, there is a statistically significant association between observations recorded within the homeopathic materia medica and the expected physiological mechanisms for the corresponding undiluted substances.

Effect of Homeopathic Medicines and a Nosode on Larvae of Cochliomyia hominivorax (Diptera: Calliphoridae).

BACKGROUND: Cochliomyia hominivorax is the major fly causing primary myiasis in livestock animals in Brazil; its larvae develop in the host's living tissues, causing mutilations, which can even lead to death. In conventional treatments of myiasis, chemo-synthetic insecticides have been employed directly on larvae present in the wounds. Homeopathy may represent a healthy and sustainable alternative both to prevent and to treat myiasis in animals and humans. The current study evaluated how the emergence of adult insects is affected by the use of the homeopathic medicines Sulfur 12cH and Pyrogenium 12cH, and the nosode produced from C. hominivorax larvae at potencies 8cH and 12cH, on third-stage larvae of a C. hominivorax colony. MATERIALS AND METHODS: The homeopathic medicines and the nosodes were produced according to the Brazilian Homeopathic Pharmacopoeia. Control groups were distilled water, alcohol, no substance, and the organophosphate insecticide trichlorfon. For each group, 10 replicates were performed. Emergence rate of adult insects was evaluated by descriptive statistics followed by analysis of variance. Homogeneity of variances was verified by F-test and group means were compared with Tukey's test. RESULTS: Mortality rates in control groups were 2.7% for 30% (v/v) alcohol, 4.3% for distilled water, 3.2% for no substance (p > 0.05). In the trichlorfon group, the mortality rate of larvae was 90.8%. For Sulfur 12cH, the mortality of larvae was 94.6%, and for Pyrogenium 12cH it was 98.6%. The latter three means were not statistically different from each other or from the mean found for the trichlorfon group. The mortality rates of larvae were 61.3% and 66.6% for nosode C. hominivorax 8cH and 12cH, respectively (p > 0.05). CONCLUSIONS: Results suggest that homeopathy could be used therapeutically to prevent and treat animals and humans with myiasis caused by C. hominivorax.

Gastroprotective effects of Kangfuxin against water-immersion and restraint stress-induced gastric ulcer in rats: roles of antioxidation, anti-inflammation, and pro-survival.

Context: Kangfuxin (KFX) is widely used for the treatment of gastric and duodenal ulcer; however, more research is needed to determine the protective mechanisms of KFX in ameliorating gastric ulcer.Objective: To investigate the efficacy and potential mechanism of Kangfuxin liquid (KFX) in water-immersion and restraint stress (WIRS)-induced gastric ulcer.Materials and methods: Seventy rats were randomly divided into seven groups (n = 10) as follows: the control group (normal saline, i.g.), the model group (normal saline, i.g.), the KFX groups (2.5, 5 and 10 mL/kg, i.g.), the omeprazole group (20 mg/kg, i.p.) and Sanjiuweitai Granules group (1850 mg/kg, i.g.). The WIRS model was applied to induce stress ulcers after 7 days of drug administration. Afterwards, rats were sacrificed at 10 h induced by WIRS.Results: Pre-treatment with KFX (5,10 mL/kg) could effectively reduce the area of gastric ulcers and improve the pathological changes of ulcerated tissue. Moreover, KFX (5,10 mL/kg) increased the prostaglandin E2 (52%) and cyclooxygenase-1 (30%) levels, and improved malondialdehyde (54%), superoxide dismutase (58%), catalase (39%), and nitric oxide (11%) and TNF-α (9%), IL-6 (11%), MMP-9 (54%) and MMP-2 (53%) of ulcer tissue. Furthermore, pre-treatment with KFX dramatically increased IGF-1, PTEN, and Akt protein expression.Conclusions: Our results suggest that KFX has protective effects on WIRS-induced gastric ulcer via inflammatory reactions, oxidative stress inhibition, and pro-survival action, which were the results of activating the IGF-1/PTEN/Akt signalling pathway. Our results provide evidence of KFX for treating gastric ulcer.

[Diuretic effect and material basis of Clematidis Armandii Caulis in rats].

To search for the active diuretic fractions of Clematidis Armandii Caulis( CAC) and determine its main active chemical components by using liquid chromatography-mass spectrometry( LC-MS) and diuretic activity evaluation. CAC 75% ethanol extracts and extracts from different polar solvents were orally administered to saline-loaded rats at different doses. 6 h urinary volume,p H and contents of electrolyte Na+,K+and Cl-were measured. The chemical components of the active fractions were separated and identified by ultra performance liquid chromatography-electrospray ionization-quadrupole time of flight-mass spectrometry( UPLC-ESI-Q-TOF-MS/MS) method. As compared with the control group,the urine volume was increased by 44%( P< 0. 01) and 34%( P < 0. 05) in CAC75% ethanol extract 57. 74 and 28. 8 mg·kg-1 groups respectively; the Na+excretion was increased by 52%( P< 0. 01) and 45%( P<0. 05),respectively; while the Cl-excretion was increased by 101%( P<0. 01) and 85%( P<0. 05),respectively. The urine volume,Na+excretion and Cl-excretion were increased by 50%( P< 0. 01),58%( P< 0. 05),and 65%( P< 0. 05) respectively in petroleum ether extract 70. 98 mg·kg-1 group as compared with the control group. While for the n-butanol extract 194. 18 mg·kg-1 group,the urine volume,Na+and Cl-excretion were increased by 42%( P<0. 01),41%( P<0. 05) and 97%( P<0. 01),respectively. The diuretic activity of other fractions was not obvious. There was no statistical difference in K+excretion in all groups. The results of LC-MS analysis showed that six compounds,including two sterols,one chromogen and three fatty acids,were identified from petroleum ether extract.Fourteen compounds,including six triterpenoid saponins,six lignin glycosides,one sterol glycoside and one phenolic glycoside,were identified from the n-butanol extract. All the results suggested that the ethanol extract of CAC had remarkable diuretic activity and its main effective components included sterol,triterpenoid saponin and lignin glycosides.

Ultra-High Dilutions and Homeopathy: Can They Be Explained without Non-Local Theory?

We discuss questions related to the 'Benveniste Affair', its consequences and broader issues in an attempt to understand homeopathy. Specifically, we address the following points: 1.: The relationship between the experiments conducted by Benveniste, Montagnier, their collaborators and groups that independently tested their results, and 'traditional' homeopathy. 2.: Possible non-local components such as 'generalised entanglement' as the basis of the homeopathic phenomenon and experimental evidence for them. 3.: The capability of highly diluted homeopathic remedies to provoke tangible biological changes in whole organisms and cellular experimental systems. 4.: Aspects of the similia principle related to the above. 5.: Suggestions that can lead to experimental verifications of the non-local hypothesis in homeopathy.

Symptom Similarity versus Disease Similarity: Revisiting the Application of the Law of Similars and Challenging the Symptom-Centric Approach in Homeopathy.

The system of homeopathic medicine is based on the Law of Similars. It is often implied by students and practitioners of homeopathy that the fundamental principle suggests that if the substance is capable of producing certain 'symptoms', it can also remove, treat, or 'annihilate' similar symptoms if the same substance is administered in a small dose. Hahnemann clearly highlights the importance of pathogenesis or 'disease-producing power', and not just the symptoms-producing power, as a part of the 'totality of the disease'. The author perceives the need for a rectification in the symptom-centric approach in homeopathy. The pathogenesis of disease includes the mechanisms and the cause, which are more complete than the consideration of mere symptoms. Thus, the fundamental approach needs to be extended beyond the symptoms' similarity to the disease-pathogenesis similarity. Several clinical examples are given based on the imaginary expansion that is constructed on the 'mind' symptoms without the inclusion of the pathogenesis of the medicinal substance, suggesting the limitations and the risks to homeopathy of a purely symptom-centric approach.

Phase-Transition-Induced Pattern Formation Applied to Basic Research on Homeopathy: A Systematic Review.

BACKGROUND: Methods based on phase-transition-induced pattern formation (PTPF) are increasingly used in medical research. Frequent application fields are medical diagnosis and basic research in homeopathy. Here, we present a systematic review of experimental studies concerning PTPF-based methods applied to homeopathy research. We also aimed at categorizing the PTPF methods included in this review. MATERIALS AND METHODS: Experimental studies were collected from scientific databases (PubMed, Web of Science, Russian eLibrary) and from experts in the research field in question, following the PRISMA guidelines. The studies were rated according to pre-defined scientific criteria. RESULTS: The review included 15 experimental studies. We identified seven different PTPF methods applied in 12 experimental models. Among these methods, phase-transition was triggered through evaporation, freezing, or solution, and in most cases led to the formation of crystals. First experimental studies concerning the application of PTPF methods in homeopathic research were performed in the first half of the 20th century; however, they were not continued in the following years. Only in the last decade, different research groups re-launched the idea, introducing new experimental approaches and computerized pattern evaluation techniques. The here-identified PTPF methods are for the first time proposed to be classified as one group of methods based on the same basic physical phenomenon. CONCLUSIONS: Although the number of experimental studies in the area is still rather limited, the long tradition in the application of PTPF methods and the dynamics of the present developments point out the high potential of these methods and indicate that they might meet the demand for scientific methods to study potentized preparations.
