37. Impacto da reabilitaÃÃo pulmonar nos marcadores inflamatÃrios prÃ-operatÃrios e nas complicaÃÃes pulmonares pÃs-operatÃrias de pacientes com cÃncer de pulmÃo candidatos a ressecÃÃo pulmonar / Impact of pulmonary rehabilitation in inflammatory markers in preoperative and postoperative pulmonary complications in patients with lung cancer candidates in pulmonary resection
Lung cancer (LC) is a malignant aggression which can be also surgically treated characterized by inflammation and higher mortality rates. Pulmonary complications are still concerning. The choice of studying fibrinogen and albumin is due to the fact that they are active inflammatory markers in LC often associated with chronic obstructive pulmonary disease. Pu

38. Crotoxina: uma nova abordagem na inflamação alérgica pulmonar em ratos. / Crotoxin: a new approach for the modulation of lung allergic inflammation in rats.
A crotoxina (CTX) é a principal toxina do veneno de serpentes Crotalus durissus terrificus, caracterizada como b-neurotoxina com ação principalmente pré-sináptica, inibindo a liberação de acetilcolina nas junções neuro-musculares. No entanto, vários dados de literatura têm mostrado que, adicionalmente à atividade neurotóxic

39. Exposição precoce ao poluente 1,2-naftoquinona (1,2-NQ) e a susceptibilidade diferencial à inflamação pulmonar em camundongos C57BL/6 machos e fêmeas. / Early exposure to the pollutant 1,2-naphthoquinone (1,2-NQ) and differential susceptibility to lung inflammation in male and female C57BL / 6 mice.
Avaliou-se neste estudo a influência da exposição precoce ao poluente 1,2-NQ na resposta inflamatória alérgica em camundongos C57BL/6 machos e fêmeas, na juventude. Tanto nas fêmeas quanto em machos a 1,2-NQ não afetou a hiperreatividade (HR) nas vias aéreas. A HR foi maior nas fêmeas alérgicas, na ausência ou presença da 1,2-NQ. Camundongos mac

40. Short-term exposure of mice to cigarette smoke and/or residual oil fly ash produces proximal airspace enlargements and airway epithelium remodeling
Chronic obstructive pulmonary disease (COPD) is associated with inflammatory cell reactions, tissue destruction and lung remodeling. Many signaling pathways for these phenomena are still to be identified. We developed a mouse model of COPD to evaluate some pathophysiological mechanisms acting during the initial stage of the disease. Forty-seven 6- to 8-week-

41. Inactivation of capsaicin-sensitive nerves reduces pulmonary remodeling in guinea pigs with chronic allergic pulmonary inflammation
Pulmonary remodeling is an important feature of asthma physiopathology that can contribute to irreversible changes in lung function. Although neurokinins influence lung inflammation, their exact role in the extracellular matrix (ECM) remodeling remains to be determined. Our objective was to investigate whether inactivation of capsaicin-sensitive nerves modul

42. The effect of Nigella sativa extract on tracheal responsiveness and lung inflammation in ovalbumin-sensitized guinea pigs
OBJECTIVE: To examine the preventive effect of a hydro-ethanolic extract of Nigella sativa on the tracheal responsiveness and white blood cell count in the lung lavage fluid of sensitized guinea pigs. METHODS: Three groups of guinea pigs sensitized to intraperitoneally injected and inhaled ovalbumin were given drinking water alone (group S), drinking water c

43. Equações estruturais aplicadas a modelos causais de câncer de pulmão / Structural equation models applied to lung cancer causal models
Introdução: O câncer de pulmão (CP) é o tipo de câncer que mais mata no mundo e o cigarro ainda é sua causa mais importante. Além disso, a alimentação tem sido associada ao CP, por ser fonte de vitaminas e aminoácidos que fazem parte do metabolismo do carbono (MC). O MC é considerado mecanismo chave na manutenção da integridade do DNA e na regu

44. Efeitos dos ácidos anacárdicos no sistema respiratório de camundongos submetidos à instilação intranasal de partículas resultantes da combustão de diesel / Effects of the anacardic acids in the respiratory system of mice after intranasal instillation of diesel exhaust particles
Os ácidos anacárdicos (AAs) provenientes do líquido da casca da castanha de caju têm propriedades antioxidantes e anti-inflamatórias. Seus efeitos são bem estabelecidos em vários sistemas in vitro, no entanto não há publicações a respeito de suas ações no tecido pulmonar. No presente estudo, foram analisados os efeitos da suplementação dos AAs

45. Infecção de gerbils (Meriones unguiculatus) com Toxocara canis : migração de larvas e estudo morfológico com pesquisa imunohistoquímica de antígenos de larvas nas lesões
Introduction. In last years, the gerbils have been used as experimental model of toxocariasis, especially for studies of ocular lesions and central nervous system. Objectives. To study the migration of larvae and lesions with immunohistochemical study in gerbils infected or re-infected with Toxocara canis. Methods. Gerbils were infected with 1,500 embryonate

46. Lung hyperinflation stimulates the release of inflammatory mediators in spontaneously breathing subjects
Lung hyperinflation up to vital capacity is used to re-expand collapsed lung areas and to improve gas exchange during general anesthesia. However, it may induce inflammation in normal lungs. The objective of this study was to evaluate the effects of a lung hyperinflation maneuver (LHM) on plasma cytokine release in 10 healthy subjects (age: 26.1 ± 1.2 years

47. Pulmonary and extra pulmonary ALI: local and systemic pathophysiological differences after short term mechanical ventilation / Alterações pulmonares e sistêmicas em modelo de lesão pulmonar aguda de etiologia pulmonar e extra pulmonar após ventilação mecânica de curto prazo
Lung inflammation may vary according to the primary site of injury and may be affected by the mechanical stress generated by mechanical ventilation (MV). Objectives: to address possible differences in lung and systemic responses in pulmonary and extra pulmonary ALI after mechanical ventilation. Methods: BALB/c mice were divided in twelve groups of six animal

48. Mechanical ventilation with high tidal volume induces inflammation in patients without lung disease
Introduction: Mechanical ventilation (MV) with high tidal volumes may induce or aggravate lung injury in critical ill patients. We compared the effects of a protective versus a conventional ventilatory strategy, on systemic and lung production of tumor necrosis factor-a (TNF-a) and interleukin-8 (IL-8) in patients without lung disease. Methods: Patients with
