Stimulation of lymphocyte anti-melanoma activity by co-cultured macrophages activated by complex homeopathic medication.

BACKGROUND: Melanoma is the most aggressive form of skin cancer, and the most rapidly expanding cancer in terms of worldwide incidence. Chemotherapeutic approaches to treat melanoma have been uniformly disappointing. A Brazilian complex homeopathic medication (CHM), used as an immune modulator, has been recommended for patients with depressed immune systems. Previous studies in mice have demonstrated that the CHM activates macrophages, induces an increase in the number of leukocytes and improves the murine response against Sarcoma-180. METHODS: Here we studied the interaction of mouse lymph node lymphocytes, co-cultured in vitro with macrophages in the presence or absence of the CHM, with B16F10 melanoma cells. RESULTS: Lymphocytes co-cultured with macrophages in the presence of the CHM had greater anti-melanoma activity, reducing melanoma cell density and increasing the number of lysed tumor cells. There was also a higher proportion of activated (CD25+) lymphocytes with increased viability. Overall, lymphocytes activated by treatment destroyed growing cancer cells more effectively than control lymphocytes. CONCLUSION: Co-culture of macrophages with lymphocytes in the presence of the CHM enhanced the anti-cancer performance of lymphocytes against a very aggressive lineage of melanoma cells. These results suggest that non-toxic therapies using CHMs are a promising alternative approach to the treatment of melanomas. In addition, they are attractive combination-therapy candidates, which may enhance the efficacy of conventional medicines by improving the immune response against tumor cells.

[Tumor inhibiting and immunoloregulation effects of Mylabris Mixture on H22 cancer-bearing mice].

OBJECTIVE: To investigate the mechanisms of tumor inhibiting and immunoloregulation of Mylabris Mixture on H22 cancer-bearing mice. METHODS: H22 cancer-bearing mice were chosen to observe the effects of tumor inhibiting and detect the proliferation function of T lymphocytes, the toxicity function of NK cells, the changes of T lymphocytes and the contents of interferon-gamma and interleukin-4. RESULTS: Mylabris Mixture could obviously inhibit the growth of H22 cancer in mice, and the tumor inhibition rat was 65.76%. The stimulation index of T lymphocyte transformation and percentage of NK cells in Mylabris Mixture-treated group were obviously higher than those in the normal control group. The subpopulation proportion of T lymphocytes in Mylabris Mixture-treated group was changed more than the normal control group. The production of interferon-gamma and interleukin-4 by T lymphocytes obviously increased in Mylabris Mixture-treated group (P<0.05, P<0.001). CONCLUSION: Mylabris Mixture has the effect of inhibiting the growth of tumor constitution, and regulating immunological function on mice with tumor. Its mechanisms include the reinforcement of T lymphocyte immune function, NK cell killing function and humoral immune function.

The effect of perioperative analgesic drugs omnopon and dexketoprofen on the functional activity of immune cells in murine model of tumor surgery.

We aimed to investigate the effect of perioperative analgesia with nonselective cyclooxygenase-2 inhibitor dexketoprofen and opioid drug omnopon on the functional activity of immune cells in tumor excision murine model. Lewis lung carcinoma cells were transplanted into hind paw of C57/black mice. On the 23th day tumor was removed. Analgesic drugs were injected 30 min before and once a day for 3 days after the surgery. Biological material was obtained a day before, 1 day and 3 days after the tumor removal. IFN-γ, IL-4, IL-10 and TGF-ß mRNA levels in splenic cells were assessed by quantitative real-time RT-PCR. Cytotoxic activity of splenocytes was estimated by flow cytometry. We found that in splenocytes of mice received opioid analgesia IL-10 mRNA level was increased 2.3 times on day one after the surgery compared to preoperative level (P < 0.05), while in dexketoprofen group this parameter did not change. IFN-γ gene expression level on day 3 after tumor removal was 40% higher in splenocytes of dexketoprofen treated mice as compared with omnopon treated animals (P < 0.05). Cytotoxic activity of splenocytes on day 3 postsurgery was (62.2 ± 2.4)% in dexketoprofen against (50.2 ± 3.3)% in omnopon group. In conclusion, perioperative analgesia with cyclooxygenase inhibitor dexketoprofen in contrast to opioid analgesia with omnopon preserves higher functional activity of murine immune cells in the experimental model of tumor surgery.

Efecto del Mercurius-Heel®s sobre la citotoxicidad de fibroblastos gingivales humanos en un modelo in vitro / Effect of Mercurius-Heel®s on the cytotoxicity of human gingival fibroblasts in an in vitro model

La enfermedad periodontal es una patología de origen infeccioso, caracterizada por ocasionar secuelas destructivas al tejido de soporte del diente, y cuyo tratamiento va encaminado a la destrucción de los agentes etiológicos y a la regeneración periodontal. Una alternativa es el uso de agentes homeopáticos ya que son naturales y se administran a muy bajas concentraciones, uno de ellos es el Mercurius Heel® S como coadyuvante en enfermedades infecciosas. En este trabajo se presentan los resultados de una investigación cuyo objetivo fue evaluar el efecto del Mercurius Heel® S en la viabilidad de fibroblastos gingivales humanos, que fueron sometidos a tratamiento con Mercurius Heel® S durante 15 minutos y dos horas a concentraciones desde 300mg hasta 0.00006mg. Transcurridos esos tiempos, se retiró el tratamiento y las células fueron mantenidas durante 24, 48 y 72 horas más. Posteriormente se realizó un ensayo colorimétrico de viabilidad y proliferación celular denominado MTS de promega® Los fibroblastos gingivales humanos tratados con Mercurius Heel® S mostraron un aumento en la proliferación celular comparada con las células no tratadas. Bajas concentraciones del medicamento 0,0001mg y 0,00006mg mostraron una mayor proliferación observando diferencias estadísticamente significativas. El tratamiento a 15 minutos mostró mejores resultados con respecto al tratamiento de 2 horas con diferencias estadísticamente significativas también. Finalmente el efecto del Mercurius Heel® se mantuvo hasta las primeras 48 horas. Considerando lo anterior, el Mercurius Heel® no presentó ningún efecto citotóxico en los fibroblastos gingivales; por el contrario, las células proliferaron, lo que sugiere su utilidad como tratamiento complementario en la enfermedad periodontal.

Periodontal disease is pathology of infectious origin, characterized because it causes destructive consequences to the supporting tissue of the tooth, its treatment is aimed at the destruction of the etiologic agents and to the periodontal regeneration. An alternative is the use of homeopathic agents because they are natural and are managed to very low concentrations, one of them is the Mercurius Heel ® S as an adjunctive therapy in infectious diseases. In this work, we present the results of an investigation whose objective was to evaluate the effect of Mercurius Heel® S on the viability of human gingival fibroblasts, which were undergoing treatment with Mercurius Heel® S for 15 minutes and two hours to concentrations from 300mg to 0.00006mg. After these times, the treatment was removed and the cells were maintained for 24, 48, and 72 more hours. It was followed by a colorimetric assay for cell viability and proliferation called MTS of Promega ®. Human gingival fibroblasts treated with Mercurius Heel® S showed an increase in cell proliferation compared with the untreated cells. Low medication concentrations of 0.0001 mg and 0.00006 mg showed a greater proliferation showed greater statistically differences. Finally, the effect of Mercurius Heel® was maintained for the first 48 hours. Considering the above, the Mercurius Heel® did not provide any cytotoxic effect on human gingival fibroblasts; on the contrary, the cells proliferated, suggesting its usefulness as supplementary treatment for periodontal disease.

Preparada pelo método cinqüenta milesimal (lm) / Evaluación físico-química y citotóxica de soluciones altamente diluídas de Euphorbia tirucalli L. preparadas por el método homeopático cincuenta milesimal (LM)

Motivação: Embora Hahnemann tenha descrito o método LM na 6ª. Edição do Organon da Arte de Curar, poucas pesquisas tem sido feitas sobre as propriedades físico-químicas destas preparações. Além disso, ainda não existem evidências que apontem para a correlação entre propriedades físico-químicas e os efeitos biológicos das altas diluições. Objetivos: determinar características físico-químicas das preparações LM tais como condutividade elétrica, pH e índice de refração, bem como o efeito biológico em modelos experimentais. Materiais e Métodos: foi analisada uma série de diluições desde 1 lm até 10 lm de Euphorbia tirucalli L., preparada a partir do látex e do suco da planta. Para considerar as características sazonais desta planta, usamos 2 populações diferentes, colhidas uma em Junho de 2007 e outra em Maio de 2008. Além disso, o efeito citotóxico da Euphorbia tirucalli L. 5 lm foi testado em células humanas cancerosas (MCF7) através de ensaio MTT. Conclusões: Algumas diferenças entre as duas populações foram observadas. No entanto, nenhuma correlação clara pode ser observada entre as propriedades físico-químicas e a atividade biológica.

Background: although Hahnemann described the fifty-milesimal (LM) method in the 6th edition of the Organon of the Medical Art, very little research has been carried out on the physical chemical properties of these homeopathic preparations. Furthermore, there is still no evidence allowing for the correlation between the alleged physical chemical properties and the biological effects of high dilutions. Aims: to evaluate physical chemical characteristics of LM preparations including electrical conductivity, pH and refraction index, and their effect on biological experimental models. Materials and methods: preparations tested for physical chemical analysis were dilutions 1 lm to 10 lm of Euphorbia tirucalli L. prepared from the latex and the juice of the plant. To rule the seasonal characteristics of this plant, 2 different populations were used, one collected in June 2007 and the other in May 2008. Furthermore, the cytotoxic effect of Euphorbia tirucalli 5 lm was tested on human breast cancer cells (MCF7) through MTT assay. Conclusions: Some differences among the two collections were observed. However, any clear correlation could be observed between physical chemical properties and biological activity.

Cytotoxicity of leukocytes from normal and Shigella-susceptible (opium-treated) guinea pigs against virulent Shigella sonnei.

Intraepithelial lymphocytes were collected from the ileum of adult Hartley strain guinea pigs and used as effector cells in a 60-min bactericidal assay with virulent Shigella sonnei as target cells. Natural killer cytotoxicity (NKC) and antibody-dependent cellular cytotoxicity (ADCC) were measured and correlated with the resistance of the animals to infection by S. sonnei. Normal guinea pig intraepithelial lymphocytes exhibited mean NKC and ADCC values of 22.8 +/- 5.0 and 34.1 +/- 13.6, respectively. These animals were resistant to oral challenge with virulent S. sonnei. Intraepithelial lymphocytes from guinea pigs which were fasted for 4 days demonstrated NKC and ADCC values similar to those of normal animals (31.0 +/- 8.1 and 41.7 +/- 6.7, respectively). These animals also were resistant to oral challenge. Intraepithelial lymphocytes from guinea pigs which were given 1 ml of deodorized tincture of opium 2 h before cell collection demonstrated deficient NKC (4.7 +/- 4.2) and ADCC (5.3 +/- 4.9) values but remained resistant to infection by S. sonnei. When guinea pigs were fasted for 4 days and given opium, deficient NKC (2.0 +/- 2.0) and ADCC (1.3 +/- 1.3) values were demonstrated; this group of animals was susceptible to infection by S. sonnei (P less than 0.04). These experiments demonstrated that opium treatment depresses one form of gut immunity. When combined with starvation, opium treatment may increase susceptibility to infection by shigellae by modulation of immunity in addition to the effects on gut motility and bacterial flora.
