13. Composto homeopático reduz a liberação de ânion superóxido pelas células mononucleares de ema (Rhea americana)
The action of the "Stress Factor Ostrich (Arenales - Fauna and Flora)" was tested in the release of superoxide anion by cells in the peripheral blood of rhea (Rhea americana). Sixteen samples of 0.5mL of venous blood were collected through the jugular vein in the morning and placed in heparinized tubes. The leukocytes were separated into polymorphonuclear (P

14. Efeito modulador da ouabaína no sistema imunológico
Initially known as a cardiotonic steroid capable to inhibit the Na+/K+ATPase, ouabain was identified as an endogenous substance present in human plasma, produced by the adrenal, pituitary and hypothalamus and can interfere with various aspects of immune response. In this study, which aimed to study the modulating effect of ouabain on the immune system in viv

15. Cell migration induced by Leishmania (Leishmania) amazonensis, Leishmania (Leishmania) major and Leishmania (Viannia) braziliensis into the peritoneal cavity of BALB/c mice
In American cutaneous leishmaniasis, the initial infection phase is characterized by recruitment of neutrophils and monocytes. The migration of these cells in response to the presence of Leishmania in the peritoneum of affected animals remains unclear. The objective of this study was to investigate cell migration to the peritoneum of BALB/c mice after infect

16. Modulação de eventos da imunidade humoral e celular por venenos brutos e componentes dos venenos de Bothrops jararacussu e Bothrops pirajai / Modulation of events of humoral and cellular immunity by crude venom and components of Bothrops jararacussu and Bothrops pirajai
Snakes of the genus Bothrops are responsible for 90% of snakebites in Brazil. Their venoms cause local effects in humans and animals, such as hemorrhage, edema, pain and necrosis, characteristic of an inflammatory response. The mechanism is not well defined. These effects are related to the combined action of proteases, substances that induce bleeding and ph

17. Histopathology of Leishmania major infection: revisiting L. major histopathology in the ear dermis infection model
We describe the relationship between lesion outcome and histopathological hallmarks in susceptible (BALB/c) and resistant (C57BL/6 and IL-4-deficient BALB/c) mouse strains over the course of a 12-week-infection with Leishmania major in the ear. The infiltration of mononuclear cells and polymorphonuclear cells occurred within 6 h and mononuclear cells predomi

18. Componentes imunológicos do colostro bovino: células, teores de imunoglobulinas e atividade bactericida dos fagócitos para a Escherichia coli enterotoxigênica (ECET) / Immunological components of bovine collostrum: cells, immunoglobulin content and bactericidal activity of phagocytes against enterotoxigenic Escherichia coli
Bovine collostrum citology, immunoglobulin content and bactericidal activity of phagocytes against enterotoxigenic Escherichia coli were studied qualitatively and quantitatively, analyzing the influence of previous opsonization of the bacterium. In order to achieve this aim, 53 Holstein cows were used to obtain 212 collostrum samples before the first and sec

19. Hematological and hemostatic alterations induced by clofazimine and clarithromycin in rats / Alterações hematológicas e hemostáticas induzidas pela clofazimina e claritromicina em ratos
Clarithromycin and clofazimine have been used to treat leprosy and tuberculosis as well as infections of Mycobacterium avium complex, an ordinary complication in patients who are in advanced stage of Acquired Immunodeficiency Syndrome (AIDS). As the data about the toxicity of therapeutic schemes including those drugs are scarce, this research had the aim to

20. Prevalence and pathology of the nematode Heterakis gallinarum, the trematode Paratanaisia bragai, and the protozoan Histomonas meleagridis in the turkey, Meleagris gallopavo
The prevalence of infection and associated pathology induced by two helminth and one protozoan species infecting Brazilian turkeys are reported. The intestinal nematode Heterakis gallinarum appeared with a prevalence of 70% in the infected birds, without gross lesions when not associated to the protozoan Histomonas meleagridis. Histological findings in the c

21. Genetic potential for an acute inflammatory response in IgA glomerulonephritis in mice
Mice selected on the basis of an acute inflammatory response (AIR) can provide information about the immunopathological mechanisms of glomerulonephritis. We studied the differences between mice selected for a maximal AIR (AIRmax that attract more polymorphonuclear cells to the site of injury) or a minimal AIR (AIRmin that attract more mononuclear cells) in a

22. Toxicity of a cyanobacterial extract containing microcystins to mouse lungs
Toxic cyanobacteria in drinking water supplies can cause serious public health problems. In the present study we analyzed the time course of changes in lung histology in young and adult male Swiss mice injected intraperitoneally (ip) with a cyanobacterial extract containing the hepatotoxic microcystins. Microcystins are cyclical heptapeptides quantified by E

23. Investigation of predominant cell types and subtypes and expression of the inducible nitric oxide synthase enzyme (iNOS) in oral paracoccidioidomycosis / Estudo dos tipos e subtipos celulares predominantes e da expressão da enzima óxido nítrico sintase induzível (iNOS) na Paracoccidioidomicose Bucal
Paracoccidioidomycosis is a chronic granulomatous disease that induces a specific inflammatory and immune response. The participation of nitric oxide (NO), a product of the inducible nitric oxide synthase enzyme (iNOS), as an important fungicidal molecule against Paracoccidioides brasiliensis has been demonstrated. In order to further characterize the oral l

24. Hepatic changes in mice chronically infected with Helicobacter trogontum
We infected NIH germ-free female mice with Helicobacter trogontum, a recently described intestinal bacterium of rats, in order to study the lesions it induced in the liver of this host. Fifteen mice were challenged with a single dose of H. trogontum (test group) and killed 6, 12 and 18 months after inoculation (5 animals/group). Nine animals were challenged
