RESUMO
INTRODUCTION: Canova is a complex homeopathic medicine that enhances a specific immunologic responses against several exogenous and endogenous conditions. Canova activates macrophages both in vivo and in vitro. AIM AND METHOD: We evaluated the effects of macrophages activated by Canova in vivo and ex vitro in the proliferation of lymphocytes. Canova was used to activate Cebus apella macrophages in vivo or ex vitro with Canova. Lymphocytes were cultured with the macrophage culture medium. The analysis of Canova effects in cultured lymphocytes was performed according to the cell cycle phase using flow cytometry. The Interferon gamma and Interleukin-5 cytokines quantification in these lymphocyte culture media was performed by Enzyme-linked immunosorbent assay (ELISA). RESULTS: We observed that Canova actives macrophages in vivo and ex vitro. The lymphocytes cultured in a supplemented medium with macrophages activated by Canova treatment presented a higher number of proliferation cells than lymphocytes not exposed to macrophages activated by Canova. The Interferon gamma and Interleukin-5 cytokines were only observed in the medium of lymphocytes exposed to macrophages activated by Canova. Thus, Canova has potential as a new adjuvant therapy.

Glycerol monolaurate (GML) is a naturally occurring antimicrobial agent used commercially in numerous products and food items. GML is also used as a homeopathic agent and is being clinically tested to treat several human diseases. In addition to its anti-microbial function, GML suppresses immune cell proliferation and inhibits primary human T cell activation. GML suppresses T cell activation by altering membrane dynamics and disrupting the formation of protein clusters necessary for intracellular signaling. The ability of GML to disrupt cellular membranes suggests it may alter other cell types. To explore this possibility, we tested how GML affects human B cells. We found that GML inhibits BCR-induced cytokine production, phosphorylation of signaling proteins, and protein clustering, while also changing cellular membrane dynamics and dysregulating cytoskeleton rearrangement. Although similar, there are also differences between how B cells and T cells respond to GML. These differences suggest that unique intrinsic features of a cell may result in differential responses to GML treatment. Overall, this study expands our understanding of how GML impacts the adaptive immune response and contributes to a broader knowledge of immune modulating monoglycerides.

The mechanism underlying bee venom (BV) therapy is still controversial, with opinions ranging from constituent-based pharmacological action to homeopathic-like activity. The purpose of this study was to examine whether BV phospholipase A2 (bvPLA2), an enzymatic component of BV, is a novel anti-inflammatory and anti-arthritic mediator capable of stimulating CD25+ Foxp3+ regulatory T cell (Treg) polarization in a mouse model of human rheumatoid arthritis (RA). An experimental model of RA was established in male DBA/1 mouse by 2-week-interval injections of 100 µg type II collagen emulsified in complete (first injection) or incomplete Freund's adjuvant (second injection) at the base of the tail. During arthritis development, bvPLA2 (0.1, 0.5, 1.0 mg/kg) and/or Treg inhibitors such as anti-CD25 antibodies and peptide 60 (P60) were injected intraperitoneally for 5 weeks. Arthritic symptoms and the expansion of Tregs were then assessed by behavioral assessments, histological and micro-CT imaging, and flow cytometry. bvPLA2 injections significantly alleviated arthritic behaviors such as squeaking and joint swelling, consistent with changes seen on both histological and micro-CT images. The anti-arthritic effects of bvPLA2 were blocked by intraperitoneal injections of 0.25 mg/kg anti-CD25 antibody and 10 µg/kg P60, as determined by behavioral assessments. Flow cytometric analysis of dendritic cells, B cells, and major T cell subsets from spleens revealed a significant depletion of Tregs following anti-CD25 antibody, but not P60, treatment. bvPLA2 treatment exerted significant anti-inflammatory and anti-arthritic activities in a mouse model of RA via the induction of Tregs.

INTRODUCTION: Canova (CA) is a homeopathic medication with immunomodulatory properties, recommended for patients with a depressed immune system. CA has been reported to increase in leukocyte numbers, cellular differentiation and reduction in tumor size. AIM AND METHOD: Since CA may stimulate lymphocyte differentiation, proliferation, and/or survival, the aim of the present study was to compare the mitotic index (MI) of phytohemagglutinin-stimulated human lymphocytes cultured in a medium supplemented with human macrophages activated by CA, with lymphocytes cultured in a medium without CA-treated macrophages. RESULTS: In this study, the MI of lymphocyte cultured received the medium containing CA-stimulated macrophages showed a higher proliferation index (p<0.01) than the lymphocytes cultured in a medium without CA-treated macrophages. Our results suggest that CA treatment, in addition to activating macrophages, indirectly induces lymphocyte proliferation and has potential as a new adjuvant therapeutic approach.

Effects of Saussurea lappa root extracts prepared in ethanol according to the homeopathic principles were assessed on leukocyte phagocytic activity, lymphocyte transformation and mitogen-induced interferon-gamma (IFN-gamma) in the cultures of peripheral blood mononuclear cells of goats (PBMC) in vitro. Leukocyte phagocytic activity was measured by flow cytometry, lymphocyte proliferation by MTT and IFN-gamma level in cell culture supernatants was determined by ELISA. The results obtained demonstrated that all test dilutions (D4, D6, D8) of Saussurea lappa in ethanol have exerted a stimulating effect on leukocyte phagocytic activity in dose-dependent manner. A 10 microl dose of Saussurea lappa of each dilution markedly enhanced phagocytic activity, while other doses tested made only a feeble stimulating effect. The increases with 10 microl dose were found significantly (P<0.01) different between each dilution, maximal stimulation was observed by D8 dilution. Different doses (10 microl, 2 microl, 1 microl, 0.5 microl) of all test dilutions (D4, D6, D8) of Saussurea lappa in sterile 0.9% NaCl solution inhibited lymphocyte proliferation. Maximal inhibitory effect was observed with the 2 microl dose. Similarly, Saussurea lappa suppressed the secretion of IFN-gamma by mitogen-activated (PHA; 2.5 microg/ml) of peripheral mononuclear cells in dose-dependent manner. In conclusion these findings suggest that enhanced leukocyte phagocytic activity may be helpful to clear the soluble immune complexes produced during a sustained immune response against self antigens which causes chronic inflammatory injury of tissue. On the other hand, inhibition of lymphocyte proliferation and IFN-gamma by Saussurea lappa may contribute to suppress immune-mediated inflammatory reactions possibly through a cell-mediated cytokine pathway. Thus it is concievable that ethanolic extracts of Saussurea lappa roots in homeopathetic dilutions may be considered as a potential candidate for therapeutic support in autoimmune and chronic inflammatory disorders.

The authors propose a new treatment policy for opisthorchiasis, which is intended for the body's self-regulation and based on the use of antihomotoxic therapy. Forty patients with the verified diagnosis of chronic opisthorchiasis were examined. Antihomotoxic therapy was found to have high clinical (85%) and parasitological (75%) effects, The application of an aggregate clinical estimate showed a positive role of episodes of development of acute inflammatory reactions, fever, and reversion of prior diseases, which favors the restoration of the body's responsiveness and the particular efficiency of the therapy performed. The results of helminthoovoscopy are interpreted in the context of clinical data. There was a significant increase in the count of HLA DR monocytes and in the level of IgA and a reduction in IgE and IL-4 with a substantial rise in the cellular production of other cytokines.

Suspensions of Walker and HeLa cells, rat fibroblasts and human stimulated lymphocytes were incubated over various periods with the synthetic amino steroid, 2 beta,16 beta-dipiperidino-5 alpha-androstane-3 alpha,17 beta-diol dipivalate (DAP). The acute cell destroying effect was found to be exponentially time and dose dependent within a certain range. With lower nontoxic doses, decreases in the mitotic and labelling indices were observed, and clotted mitotic figures occurred. The effects were essentially the same for all experimental cell types; chromosome alterations were not seen.

The aim of this study was to evaluate the effects of opium addiction on the secretion of IL-4, IFN-γ, IL-6 and TGF-ß under in vivo and in vitro conditions. The blood samples were collected and PBMCs were cultured in RPMI1640 with and without opium for 48 h. The levels of the cytokines were measured using ELISA technique. The results showed that plasma levels of IL-4 and IFN-γ were significantly lower and IL-6 and TGF-ß were higher in plasma taken from opium-addicted subjects. The concentrations of all the cytokines in opium-addicted subjects in in vitro condition were significantly lower than the control group. Addicted subjects cultured lymphocytes significantly decrease secreted IL-4, IL-6 and TGF-ß but not IFN-γ in response to being cultured with opium, where as IFN-γ was increased in controls. These results may explain the frequent microbial infections and an increased tumor incidence seen in addicted patients.

BACKGROUND: Canova activates macrophages and indirectly induces lymphocyte proliferation. Here we evaluated the effects of Canova in cyclophosphamide-treated non-human primates. METHODS: Twelve Cebus apella were evaluated. Four animals were treated with Canova only. Eight animals were treated with two doses of cyclophosphamide (50 mg/kg) and four of these animals received Canova. Body weight, biochemistry and hematologic analyses were performed for 40 days. Micronucleus and comet assays were performed for the evaluation of DNA damage. RESULTS: We observed that cyclophosphamide induced abnormal WBC count in all animals. However, the group treated with cyclophosphamide plus Canova presented a higher leukocyte count than that which received only cyclophosphamide. Cyclophosphamide induced micronucleus and DNA damage in all animals. The frequency of these alterations was significantly lower in the Canova group than in the group without this medicine. CONCLUSIONS: Our results demonstrated that Canova treatment minimizes cyclophosphamide myelotoxicity in C. apella.

Traumeel S (Traumeel), a mixture of highly diluted (10(-1)-10(-9)) extracts from medicinal plants and minerals is widely used in humans to relieve trauma, inflammation and degenerative processes. However, little is known about its possible effects on the behavior of immune cells. The effects of Traumeel were examined in vitro on the ability of resting and PHA-, PMA- or TNF-alpha-activated human T cells, monocytes, and gut epithelial cells to secrete the prototypic pro-inflammatory mediators IL-1beta, TNF-alpha and IL-8 over a period of 24-72 h. Traumeel inhibited the secretion of all three agents in resting, as well as activated immune cells. IL-beta secretion was reduced by up to 70% in both resting and activated cells; TNF-alpha secretion was reduced by up to 65 and 54%, respectively, and IL-8 secretion was reduced by 50% in both resting and activated cells (P < 0.01 for all cells). Interestingly, the effect appeared to be inversely dose-related; maximal inhibition (usually 30-60% inhibition; P < 0.01) was seen with dilutions of 10(-3)-10(-6) of the Traumeel stock material. This finding suggests that Traumeel does not inhibit immune cells functions by exerting a toxic effect. Indeed, Traumeel did not affect T cell and monocyte proliferation. Although additional studies are needed to clarify the mode of action of Traumeel and to demonstrate causative relationship between the inhibition of cytokine/chemokine secretion in cell culture and the reported clinical effects of the preparation, our in vitro results offer a mechanism for the anti-inflammatory effects of Traumeel observed in clinical use.
