13. In vitro potential cytotoxicity of an adhesive system to alveolar macrophages
O objetivo deste estudo foi avaliar o potencial de citotoxicidade do sistema adesivo Adper Single Bond 2 (SB), em função dos tempos pós-polimerização e imersão no meio de cultura para preparação dos extratos, observando-se os níveis de liberação de óxido nítrico (NO) e taxa de sobrevivência celular (MTT assay). Macrófagos alveolares de ratos W

14. Participação da proteína Beta-2 integrina no curso da infecção experimental induzida pelo Paracoccidioides brasiliensis
Paracoccidioides brasiliensis é um fungo intracelular facultativo causador da Paracoccidioidomicose (PCM), doença crônica e granulomatosa, frequente na América Latina. O principal mecanismo de defesa do hospedeiro contra a PCM é a imunidade celular mediada principalmente por macrófagos ativados por IFN-γ. A interação inicial entre macrófago-fun

15. Influência do diabetes mellitus na evolução do enfisema pulmonar induzido por elastase em ratos / Influence of diabetes mellitus on the course of pulmonary emphysema induced by elastase in rats
The present study was undertaken to investigate the role of insulin in the development of acute and chronic inflammatory responses in porcine pancreatic elastase (PPE)-induced pulmonary emphysema. Diabetic male Wistar rats (alloxan, 42 mg/kg, i.v., 10 days) and control rats were instilled with physiological saline solution containing PPE (0.25 IU/0.2 mL, rig

16. ProgramaÃÃo pela desnutriÃÃo perinatal do controle serotoninÃrgico da liberaÃÃo do Ãxido nÃtrico por macrÃfagos alveolares em ratos adultos
Restriction on nutritional feeding has long-term consequences on the functioning of neuroimmune systems. Receivers and serotonin transporter present in alveolar macrophages (AM) are related to its operation. In the article "Perinatal malnutrition programs sustainable alterations in nitric oxide production and cell viability in activated macrophages of the ad

17. Response activity of alveolar macrophages in pulmonary dysfunction caused by Leptospira infection
Leptopspirosis is a syndrome with different clinical manifestations including the most severe and often fatal forms of pulmonary disease of unknown etiology. Pulmonary injury during the inflammatory process has been associated with the excessive number of alveolar macrophages (AMs) and polymorphonuclear leukocytes stimulated in the lungs and with the product

18. Patogênese da síndrome pulmonar hemorrágica na leptospirose humana / Pathogenesis of leptospirosis pulmonary hemorrhage syndrome in human
Leptospirosis is a zoonotic disease that is a cause of high morbidity and mortality in humans and is an important public health problem. Caused by bacteria of Leptospira genus, this disease presents diverse clinical manifestations and is especially important in developing countries. Leptospirosis pulmonary hemorrhage syndrome is the major cause of death in p

19. Efeitos da separação materna sobre o comportamento, a imunidade inata e o crescimento tumoral / Maternal separation effects on the behavior, innate immunity and tumor growth
Maternal separation is one model of stress/anxiety induction. We know about it that the mammals normal emotional behavior development depends on the interaction between mother and younglet. Beside this, early life stressed events can induce deletery effects in immune response and to illness resistance for all life long. In this work we searched for the mater

20. Effects of pentoxifylline on TNF-alpha and lung histopathology in HCL-induced lung injury
OBJECTIVE: To evaluate the effects of pentoxifylline on hydrochloric acid-induced lung lesions in rats subjected to mechanical ventilation. METHODS: Twenty male, adult Wistar-EPM-1 rats were anesthetized and randomly grouped (n=5 animals per group) as follows: control-MV (mechanical ventilation, MV group); bilateral instillation of HCl (HCl group); bilateral

21. Histopathological and ultrastructural aspects of mice lungs experimentally infected with dengue virus serotype 2
Histological and ultrastructural alterations in lung tissue of BALB/c mice infected with dengue virus serotype 2 (non-neuroadapted), by intraperitoneal and intravenous routes were analyzed. Lung tissues were processed following the standard techniques for photonic and electron transmission microscopies. Histopathological and ultrastructural studies showed in

22. Chronic inhalation effects of crack cocaine in the respiratory system of mice / Efeitos da inalação crônica de cocaína "crack" no aparelho respiratório de camundongos
INTRODUCTION: One of the illegal ways of using cocaine is smoking its rock through a burning cocaine basis shaped resin (crack cocaine). The use of crack cocaine may cause chronic and severe alterations in the respiratory system. In this research, the chronic inhalation effects of "crack" cocaine in mice respiratory systems were studied. METHODS: Forty male

23. Tuberculose: estudo da formaÃÃo de padrÃes na eliminaÃÃo, contenÃÃo e disseminaÃÃo do bacilo de Koch
Tuberculosis (TB) is an endemic disease caused by an aerobic bacterium named Mycobacterium tuberculosis (Mtb). It is responsible for on third of population infected worldwide and it causes 2.2 millions deaths per year. The most common infection by Mtb occurs by inhalation of microorganisms into the lungs, where they infect mainly alveolar macrophages. The in

24. Desenvolvimento osseo e dentario : aspectos biologicos, bioquimicos e moleculares da remodelação da matriz extracelular regulada pelas metaloproteinases de matriz e seus inibidores / Dental and bone development : biology, biochemistry, and molecular aspects of the matrix metalloproteinases and their inhibitors during extracellular matrix remodeling
Our objective was to analyse the spatial-temporal distribution of MMP-2, MMP-9, TIMP-1, TIMP-2 and RECK during development of mineralized tissue (bone, enamel, and dentine) in embryos, newborn, and adult mice by immunohistochemistry and in situ hybridization. During rat amelogenesis, at the secretion phase, MMPs and RECK were immunostained in the ameloblast
