A new immunochemotherapy schedule for visceral leishmaniasis in a hamster model.

The purpose of the present study was to evaluate the efficacy of the treatment with a recombinant cysteine proteinase from Leishmania, rldccys1, associated with allopurinol or miltefosine on Leishmania (Leishmania) infantum chagasi-infected hamsters. Golden Syrian hamsters infected with L. (L.

Interleukin-9 in Immunopathology of Experimental Infection.

Chagas' disease is a parasitosis caused by , which affects approximately 8 million people worldwide. The balance between pro- and anti-inflammatory cytokines produced during immunological responses contributes to disease prognosis and progression. Parasite tissue persistence can induce chronic inflammatory stimuli, which can cause long-term tissue injury and fibrosis.

Biological Actions, Electrical Conductance and Silicon-Containing Microparticles of Arsenicum Album Prepared in Plastic and Glass Vials.

Introduction:  According to the "silica hypothesis" formulated to explain homeopathy, the information of starting materials would be transferred to cells by silica nanoparticles detached from the glassware walls by serial dilution and agitation through epitaxy. We compared the biological activity, electrical current and silicon microparticle content (by means of scanning electron microscopy/energy-dispersive X-ray spectroscopy) of high dilutions (HDs) of arsenic prepared in plastic and glass vials to investigate the role of silica in their biological effects in vitro.

Materials And Methods:  Co-cultures of macrophages and yeast () were treated with different HDs of arsenic prepared in plastic and glass vials.

M1 homeopathic complex trigger effective responses against Leishmania (L) amazonensis in vivo and in vitro.

Leishmaniasis is a term referring to a range of clinical conditions caused by protozoan parasites of the genus Leishmania, Trypanosomatidae family, Kinetoplastida order that is transmitted by the bite of certain species of mosquitoes Phlebotominae subfamily. These parasites infect hosts wild and domestic mammals, considered as natural reservoirs and can also infect humans. Leishmania are obligate intramacrophage protozoa that have exclusively intracellular life style.

Homeopathic medicine Cantharis modulates uropathogenic E. coli (UPEC)-induced cystitis in susceptible mice.

Objective: This is a random blinded placebo controlled murine experimental model to study the effects of Cantharis 6 CH, a homeopathic medicine, on E coli-induced cystitis.

Methods: 24 adult susceptible female BALB/c mice were inoculated with E coli - UPEC O4:K-:H5 by a transurethral catheter. Cantharis 6cH or vehicle (placebo) was offered to mice by free access into the drinking water (1:100), during 24 h after infection.

High dilutions of antimony modulate cytokines production and macrophage - Leishmania (L.) amazonensis interaction in vitro.

Background: In previous results mice treated with high dilutions of antimony presented reduction of monocyte migration to the site of infection with increase in B lymphocytes population in the local lymph node.

Aims: To know the mechanisms involved, a series of in vitro studies was done, using co-cultures of macrophages (RAW 264.7) and Leishmania (L.

Immunomodulation of Homeopathic Thymulin 5CH in a BCG-Induced Granuloma Model.

The present study analyzed the immune modulation mechanisms of thymulin 5CH in a granuloma experimental model. Male adult Balb/c mice were inoculated with BCG into the footpad to induce granuloma, which was quantitatively evaluated. The phenotypic characterization of phagocyte, T- and B-lymphocyte populations in the peritoneum, and local lymph node was done by flow cytometry.
